STRATEGIC REPORTChairman’s statement

Executing our catalyst projects

This year marks my 
inaugural term as 
Chairman of the 
Nostrum Board, and it is 
with great pleasure that 
I present the Company’s 
Annual Report and 
Accounts for 2023.

Stephen Whyte
Chairman and  
Non-Executive Director

I am proud that Nostrum has exhibited 
operational and financial resilience this 
year and taken key steps towards growth, 
notwithstanding various challenges. While 
we were successful in firming up our core 
operations by improving product netbacks, 
gaining production through our gas lift 
expansion and tight cost control, we also 
had to make tough decisions to ensure 
compliance with license commitments. 

In parallel, several important growth 
catalysts were set in motion, such as the 
Stepnoy Leopard acquisition, another 
upstream asset in our portfolio, the 
commencement of processing of gas 
from the Ural O&G tie-back and the 
successful and safe re-start of GTU-3. 
We now look forward to capitalising 
on these growth catalysts to maximise 
future stakeholder returns.

Stabilising our core operations
The successful completion of the bond 
restructuring in early 2023 marked a critical 
milestone for the Company’s financial 
stability, and a solid foundation for the 
delivery of our mixed-asset energy strategy.

We have achieved material production 
gains which partially offset natural declines 
in the mature Chinarevskoye field by 
expanding our gas lift system at a cost  
of approx. US$8m. We were pleased to 
report 12% quarter-on-quarter production 
increase in Q3 2023 as opposed to natural 
decline in production of around 8% 
reported in Q2 2023 vs Q1 2023. 

Despite the continuing Russia-Ukraine 
conflict the Company mitigated the 
adverse impact on product pricing by 
proactively securing alternative delivery 
routes and destinations, resulting in 
improved netbacks in 2023 and thus 
helping to improve liquidity.

Tight cost discipline continued to be a key 
focus area for management and the Board 
throughout the year. Even though the 
global economy has been asserting 
extreme inflationary pressures throughout 
2022 and 2023, we managed to keep 
unchanged our cost base required for 
maintaining activities of Chinarevskoye 
field and Ural O&G processing.

Notwithstanding the overall production 
decline from our mature field, a 20% 
year-on-year reduction in average crude 
oil prices and strong inflationary pressures 
during 2023, all of our above-mentioned 
mitigation measures helped the Company 
to remain net free-cashflow neutral in 2023, 
excluding the impact of any one-off cash 
outflows. Non-recurring payments in 2023 
included circa US$25m interest and lock-up 
fees paid on completion of the bond 
restructuring, around US$20m spent on the 
acquisition of the Stepnoy Leopard fields, 
and approximately US$25m in tax audit 

02  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

payments for prior years. All of these 
factors led to a reduction in the Company’s 
unrestricted cash balance from US$234m  
at beginning of the year to US$162m at the 
end of 2023.

Meeting our license commitments 
and maintaining regulatory 
compliance 
Ensuring compliance with our license 
commitments and various regulatory 
requirements was another area of focus 
for management and the Board during 
the year. After a careful technical risk 
assessment of available opportunities, the 
Company began a limited two-well drilling 
programme at its Chinarevskoye field in 
December 2023, which it expects to 
complete during 2024. Notwithstanding 
the inherent subsurface risks, we believe 

it increases our chances of sustaining 
production levels and optimising our assets 
as well as meeting the Company’s license 
commitments.

On the downside, the company’s operating 
subsidiary had to accept the results of 
the comprehensive tax audit covering 
2016-2021 and made relevant payments of 
US$25m in taxes and administrative fines. 
In addition, the management has continued 
to actively manage various other enquiries 
and ongoing claims by local authorities.

Mixed-asset energy strategy in 
action: executed catalyst projects
2023 was also a year of executing our 
strategic catalyst projects in alignment with 
our mixed-asset strategy. This strategy 
signifies our commitment to evaluate and 

invest in both upstream and midstream 
opportunities focusing on those where we 
see the most favourable risk/reward balance. 
This could be either by processing third 
party hydrocarbons in our world-class 
infrastructure and/or by scaling up our  
own production.

The acquisition of the subsoil use rights to 
the Stepnoy Leopard fields, a second asset 
in our upstream portfolio, is in line with our 
commitment to diversify and strengthen 
our upstream asset base. Shortly after the 
acquisition, the Board reviewed and 
authorised a two-well appraisal 
programme. High quality appraisal data 
has been captured with the flow-rate and 
pressure build-up tests confirming high 
well productivity potential.

STRATEGIC REPORTChairman’s statement

Based on this information, in March 2024, 
we made a final investment decision for the 
initial field development phase with 
forecast total capital budget of US$100m. 
The project will commence in 2024 and  
will include drilling of four development 
wells across the key reservoirs targeting 
recoverable resource potential of 30-50 
mmboe. Early cash generation from end  
of 2026 is expected to strengthen the 
self-financing capacity.

On the midstream front, a testament to this 
strategic direction was the successful 
initiation of the Ural O&G tie-back and the 
delivery of the first third-party gas to our 
treatment facility in late December 2023. 
The first well commenced production with 
a rate of around 300 thousand m3 of raw 
gas per day and Ural O&G expects to put 
four additional wells into production in 
2024. This pivotal development not only 
underscores our achievement but also 
positions us to become a major third-party 
gas processor in the region.

In addition, as we have successfully 
completed the restart of our GTU-3 with  
2.5 bcma capacity, this enhances our ability 
to capture third party volumes. As we 
celebrate this milestone, we recognise the 
potential of our underutilised, modern 
infrastructure to attract more than 4 bcma 
of third-party gas. This capability allows us 
to offer accelerated processing solutions at 
substantially lower costs compared to other 
providers, presenting a unique opportunity 
to significantly boost domestic gas supply 
by nearly 20%. Through these endeavours, 

we are poised to make a substantial 
contribution to Kazakhstan’s long-term 
gasification plan. Our gas processing 
infrastructure with significant available 
capacity, located only about 100 km north  
of the Karachaganak field, represents a 
compelling value proposition to both the 
Republic of Kazakhstan and KPO, especially 
as an alternative to increasing supplies to or 
from Russia. 

As a newly appointed Board, we have been 
closely and consistently working with the 
senior management over the past year to 
foster delivering such catalyst projects, 
which set the foundation for the future 
growth of the Company.  
Our regular and ad-hoc Board meetings 
ensured that we timely and efficiently 
address all matters and provide guidance 
to the senior management team in 
achieving strategic objectives. Further 
details on the Board activities are described 
on pages 82-87.

Our progress this year reinforces our 
commitment to becoming a key player in 
Kazakhstan’s energy sector, driving forward 
the nation’s gasification efforts and 
supporting the transition to a more 
sustainable energy future.

ESG performance
We have advanced our risk rating as 
evaluated by Sustainalytics from 40.5, 
categorised as severe, at the end of 2022  
to 30.1, now positioned in the lower 
high-risk category and just one decimal 
point away from the medium risk threshold. 

This progress has put us to at the upper 
10th percentile within the Oil & Gas 
Producers industry, in the Sustainalytics 
universe, and underscores our continuous 
efforts in environmental, social and 
governance disciplines. 

Unfortunately, on the other hand, despite 
several years of operations without 
fatalities, a tragic incident occurred during 
the year involving a 35-year-old contractor 
employee performing services for 
Zhaikmunai LLP. While engaged in 
insulation works on the stationary platform 
at GTU-3 during routine maintenance,  
the worker fell into an opening where a 
functional guardrail was missing, from a 
height of 10 meters, sustaining injuries 
which unfortunately proved fatal. 

Both a comprehensive investigation of the 
incident by the competent governmental 
authorities and Nostrum’s own internal 
investigation of the incident have been 
diligently conducted. Following on from 
those investigations Nostrum has promptly 
implemented additional occupational 
safety measures with greater supervision  
to ensure effective implementation of the 
“Permit to Work” system. Assessment  
of similar hazards was also carried out 
field-wide to further mitigate the attendant 
occupational safety risks. This occurrence 
has underscored Nostrum’s imperative to 
reinforce all safety protocols not only for 
our employees but also for those of our 
contractors.

Looking to the future
Having set the foundation for the major 
growth catalysts as described earlier,  
we are now looking forward to further 
progressing these initiatives, capitalising  
on them to maximise stakeholder returns. 
Specifically, in 2024, we anticipate start of 
the Stepnoy Leopard field development 
and a Competent Person’s Report (CPR) to 
reclassify specific resources into reserves, 
and continued processing of increasing 
volumes of Ural O&G raw gas, while in 
parallel we continue to actively search for 
additional opportunities to profitably fill the 
capacity of our processing facilities.

Following the completion of the debt 
restructuring in early 2023, our first 
communication of the new mixed-asset 
energy strategy was delivered to the 
investment community at the Capital 
Markets Day in early 2023. Following this 
event the management and the Board 
continued to engage with the shareholders 
and bondholders by arranging bilateral and 
multilateral meetings. We have also been 
actively engaging with various stakeholders 
and actively participating in prominent 
industry and leadership conferences to 
showcase the advantages of Nostrum’s 
assets in Kazakhstan. 

With our 4.2 bcm gas processing facilities, 
we are strategically placed to leverage the 
new energy transition strategy unveiled by 

Kazakhstan, which is aimed at achieving 
carbon neutrality by 2060. Natural gas, as 
a lower-emission fossil fuel, is pivotal for 
Kazakhstan’s shift towards a sustainable 
energy mix, and is in line with global trends 
for cleaner energy sources. At the same 
time, demand for marketable gas in 
Kazakhstan continues to rise, while resource 
levels have remained static primarily due to 
underinvestment in both gas processing 
facilities and gas exploration. This situation 
presents a pressing challenge, with 
forecasts predicting a gas shortage 
potentially reaching up to 8 billion cubic 
meters by 2025. Our existing gas process 
infrastructure offers the fastest possible 
startup solution at the lowest possible cost 
for nearby gas producers, including from 
the Karachaganak field.

Last but not least, we must not 
underestimate the importance and 
magnitude of the various risks and 
uncertainties the Company continues to 
face. Geopolitical uncertainties, product 
price volatility, financial and tax risks, and 
other principal risks and uncertainties as 
described on pages 34-38 of the report 
may have significant impact on the future of 
the company. Capital allocation and capital 
management challenges in the view of the 
future opportunities go hand-in-hand with 
the quickly approaching maturity of the 
bonds in 2026.

Conclusion
In conclusion, I want to express my sincere 
thanks to our investors, our dedicated 
employees, and the Government of 
Kazakhstan for another year of support  
and commitment. 

In 2023, Nostrum has experienced its first 
successes in execution of its mixed- asset 
energy strategy by implementing key 
catalyst projects in a challenging operating 
and regulatory environment, while 
maintaining a steadfast focus on ESG.

Looking ahead, we remain focused on  
our strategic direction. We are facing  
a year that will surely bring both new 
opportunities and challenges, but  
with the collective efforts of our Board, 
management, and all Nostrum employees, 
we look forward to a future of continued 
success and sustainable operations.

Market trends and our response

Since its independence in 1991, Kazakhstan has established 
itself as one of the world’s most prolific hydrocarbon centres.

Key macroeconomic and microeconomic trends

Kazakhstan’s economy
Kazakhstan's economy experienced steady 
growth, registering a 5% increase in 2023, 
up from 3.2% in 2022. This growth was 
driven by both the oil and non-oil sectors, 
significantly buoyed by increased 
investment in fixed capital, despite global 
challenges and a limited impact from the 
conflict in Ukraine. The annual inflation rate 
in Kazakhstan eased to 9.8%, down from a 
peak of 21.3% in February 2022. As inflation 
decelerated, the National bank cut the base 
rate by 1 percentage point from 16.75% to 
15.75% during the year in 2023. 

The Kazakhstani Tenge (KZT) appreciated 
by 1.7% in 2023, closing the year at  
454.56 KZT per US dollar.

What it means for us
Cost optimisation continues to be a critical 
focus for our company, aimed at preserving 
and enhancing our cash reserves. Despite 
our G&A expenses maintaining fairly 
consistent levels, we are dedicated to 
minimising any necessary cost increases 
associated with the development of new 
projects, such as Stepnoy Leopard and  
Ural O&G.

Oil prices
In 2023, Brent crude oil prices averaged 
US$82.5 per barrel, showcasing notable 
volatility and a decrease of approximately 
18.2% from the previous year, amid 
geopolitical tensions and concerns 
around crude oil demand and supply.

The escalation in Brent prices following 
the Middle East conflict in October 2023 
was driven by potential geopolitical 
impacts on supply and fears of a global 
economic slowdown. However, in 
November, several OPEC+ nations 
extended and increased their voluntary 
production cuts, amounting to 2.2 million 
barrels per day. Despite this, and the 
interim support in the third and fourth 
quarters of 2023 led by Saudi Arabia  
and Russia's production and export 
reductions, oil prices experienced a 
downward trend as the year concluded.

What it means for us
The Group’s annual revenues were 
lower in comparison with 2022 due to 
the lower commodity prices and 
decreased sales volumes in line with 
expected production decline from the 
maturing Chinarevskoye field.

At the end of 2023 we had cash reserves 
in excess of US$161.7m (31 December 
2022: US$233.6m) excluding US$16.5m 
placed in DSRA account in accordance 
with the Notes terms post-restructuring 
and US$8.7m of liquidation fund deposits, 
which are reserved as required by the 
subsoil use rights for abandonment and 
site restoration liabilities.

The decline in cash balances year-on-year 
was primarily due to the US$19.3m 
payment for acquiring an 80% stake in 
Positive Invest LLP, US$25m payment for 
tax audit and US$25m payment for 
finance costs and lock-up fees as a result 
of completion of bond restructuring.

Competitive environment
Kazakhstan and Azerbaijan are the two 
main oil-producing countries in the 
Caspian region whilst Turkmenistan 
and Uzbekistan are the predominant 
gas producers. Russia plays an important 
role in the region by providing a 
transportation corridor between the 
Caspian Sea and the Black Sea.

As the world’s largest landlocked country, 
Kazakhstan depends on an extended 
network of pipelines and railways to 
deliver its products to export markets. 
Pipeline exports are primarily delivered 
via Russia (Atyrau-Samara and the 
Caspian Pipeline Consortium pipelines); 
via Azerbaijan and Turkey (the Baku- 
Tbilisi-Ceyhan pipeline); and one via 
China (Atasu-Alashankou). Rail exports 
utilise Kazakhstan’s extensive rail network, 
reaching markets throughout the FSU and 
beyond (please refer to page 7 where we 
discuss the impact of Russian sanctions 
resulting from the Russia-Ukraine conflict 
on our business).

What it means for us
Vast distances between Central Asian 
markets, long-established trading 
relationships and in-place infrastructure 
promote co-dependency between FSU 
exporters. Kazakhstan naturally benefits 
from its geo-strategic position between 
Russia and China. Nostrum is situated at 
the heart of the export corridor that exists 
between Russia and multiple markets to 
the west of the Caspian.

Nostrum’s assets are located in the 
Pre-Caspian Basin close to the Russian 
border and in close proximity to some  
of the most significant hydrocarbon 
resources in the FSU. This advantageous 
position means that the Company has 
access to multiple export markets for its 
products, as well as labour and specialist 
equipment providers. In addition, 
Nostrum has a substantial amount of 
spare gas processing capacity in a region 
where there is a significant amount of 
stranded gas with a growing need for gas 
processing.

promote co-dependency between FSU 

exporters. Kazakhstan naturally benefits 

from its geo-strategic position between 

Russia and China. Nostrum is situated at 

the heart of the export corridor that exists 

between Russia and multiple markets to 

the west of the Caspian.

Nostrum’s assets are located in the 

Pre-Caspian Basin close to the Russian 

border and in close proximity to some  

of the most significant hydrocarbon 

resources in the FSU. This advantageous 

position means that the Company has 

access to multiple export markets for its 

products, as well as labour and specialist 

equipment providers. In addition, 

Nostrum has a substantial amount of 

spare gas processing capacity in a region 

where there is a significant amount of 

stranded gas with a growing need for gas 

processing.

At the end of 2023 we had cash reserves 

in excess of US$161.7m (31 December 

2022: US$233.6m) excluding US$16.5m 

placed in DSRA account in accordance 

with the Notes terms post-restructuring 

and US$8.7m of liquidation fund deposits, 

which are reserved as required by the 

subsoil use rights for abandonment and 

site restoration liabilities.

The decline in cash balances year-on-year 

was primarily due to the US$19.3m 

payment for acquiring an 80% stake in 

Positive Invest LLP, US$25m payment for 

tax audit and US$25m payment for 

finance costs and lock-up fees as a result 

of completion of bond restructuring.

Geopolitical uncertainty
Since the beginning of the latest conflict in the Middle East, Brent 
prices have been volatile amid potential geopolitical impact on 
supply and concerns of slowing global growth. The geopolitical 
factors have prominently led to significant fluctuations in oil prices 
and market uncertainty. 

The ongoing conflict between Russia and Ukraine, which started in 
early 2022, continues to be one of the most substantial conflicts in 
Europe and has led to widespread sanctions being imposed on 
various Russian institutions and individuals. Bodies and nations 
imposing sanctions today include the US, UK and EU and these 
sanctions have been sequentially expanding. 

Due to sanctions, Urals blend has been trading at a significant 
discount compared to Brent. Prior to the conflict, the spread 
between Brent and Urals was modest, approximately US$3 per 
barrel. However, this spread widened dramatically to around 
US$35-40 per barrel during 2022, impacting the Company's oil 
export prices. In 2023, on average, the spread between Brent and 
Urals was US$20.8 per barrel, which would have had substantial 
negative impact on the Company’s revenues, if not addressed 
actively by management to mitigate these costs related to the 
secondary effects of the Russian invasion of Ukraine.

What it means for us
Given the geographical position of the Group’s operations, 
there is an impact of the evolving situation in Ukraine on its 
business. Whilst Kazakhstan is not directly involved in the 
ongoing conflict, nor have any Western sanctions been levelled 
at it, the country is connected to Russia through infrastructure, 
banking, and other business links. Furthermore, the Company 
contracts with a limited number of Russian service companies.

During 2022 Nostrum considered and analysed alternative 
export routes where export prices are not linked to Urals 
quotation for oil and gas condensate supplies. As a result of this 
exercise, in 2023 the Company managed to achieve lower than 
average discounts for crude oil and gas condensate. 

Nostrum is committed to complying with applicable UK, EU 
and US sanctions relating to the Russia-Ukraine conflict. The 
Company has obtained advice from external legal counsel on 
the requirements for sanctions compliance, maintains and 
regularly updates lists of sanctioned persons and entities as 
these are supplemented or modified by the relevant authorities 
to prevent Group companies transacting with such persons and 
entities, has terminated previous commercial relationships that 
might be impacted by relevant sanctions, makes enquiries  
with commercial counterparties to mitigate risk of sanctions 
violations, analyses sanctions restrictions on the sale, export 
or shipment of products and consults with legal counsel when 
appropriate on questions that may arise in connection with 
the foregoing matters.

Contributing to Kazakhstan’s energy 
security, transition to cleaner energy  
and gas affordability

Kazakhstan is the largest oil producer in Central Asia and  
a major gas producer. According to BP’s Statistical Review  
of World Energy 2021, Kazakhstan stands among the top  
20 nations globally in terms of proven natural gas reserves, 
totaling 2.3 trillion cubic meters.

Kazakhstan’s gas industry plays a 
vital role in energy security
The bulk of Kazakhstan’s gas reserves lies in 
the western region of the country, with 
about 85% concentrated in major fields 
such as Tengiz, Kashagan, Karachaganak, 
Zhanazhol, and Imashevskoye. Most gas is 
associated with oil production, and around 
one-third is reinjected in order to boost 
liquids output.

In July 2022, Kazakhstan adopted a 
‘Comprehensive plan for the development 
of the gas industry of the RoK for 2022 – 
2026’, which aims to enhance the country’s 
energy and economic security through 
phased reforms and development of  
the gas industry by 2030, focusing on 
increasing gas resources, modernising 
infrastructure, meeting domestic needs, 
exporting surplus gas volumes and reforms 
in the management of gas industry.

In 2023, the volume of gas production in 
Kazakhstan reached 59.1 billion cubic 
meters, of which 29.8 billion cubic meters 
was marketable gas (which refers to the 
volume of gas available for sale after the 
processing and purification process is 
complete). With such an abundance, the 
country’s gas industry plays a vital role in 
fueling economic development and  
energy security, both domestically and 
internationally.

Despite the abundance of gas reserves in 
Kazakhstan, meeting domestic demand 
remains a significant challenge. President 
Tokayev highlighted in 2022 the potential 
shortage of commercial gas in the future, 
driven by factors such as population 
growth, a construction boom, and 
industrial development.

The issue lies in effectively extracting, 
processing, and commercialising these 
reserves. 

85% of Kazakhstan's 
reserves are concentrated  
in major fields in the western 
region of the country

Kazakhstan’s transition to  
cleaner energy 
The Republic of Kazakhstan, as outlined in 
the Decree of the President of the Republic 
of Kazakhstan from February 2, 2023 № 121, 
is committed to achieving carbon neutrality 
by 2060. This ambitious goal necessitates a 
profound transformation of the country's 
energy system, focusing on three main 
elements: decarbonisation of primary 
energy supply, electricity and heat 
production, and high-efficiency energy 
end-use in various sectors.

Switching to natural gas is a critical step  
for Kazakhstan in achieving low-carbon 
development. Natural gas, as a cleaner 
fossil fuel, can act as a bridge in the 
transition towards a more sustainable 
energy mix. It offers a reduction in 
emissions compared to coal and oil, and  
it aligns with the global trend towards 
cleaner energy sources.

Additionally, the use of natural gas can 
enhance energy efficiency and reduce 
methane leakage in the oil and gas sector.

Gas affordability to meet 
domestic demand
To support the domestic shift towards 
natural gas, the strategy includes gasification 
of regions across Kazakhstan. This initiative 
aims to increase the availability and use of 
natural gas domestically, reducing reliance 
on more polluting energy sources and 
supporting the overall goal of carbon 
neutrality. The gasification of the domestic 
market in Kazakhstan is a crucial aspect of 
the country’s energy strategy, with a current 
gasification rate of 60% of the population 
and a target rate of 65% of population  
by 2030.

The consumption of marketable gas in 
Kazakhstan is experiencing a steady 
increase, highlighting the growing demand 
for natural gas within the country. In the 
near term, projections indicate a potential 
shortage of marketable gas, underscoring 
the urgency for additional projects to 
enhance production and processing 
capacity. According to various sources, by 
2025, the expected gas deficit could range 
from 3.6 billion cubic meters to as much  
as 8 billion cubic meters.

What it means for us

The utilisation of existing capacities, such as the Nostrum GTF, may play a crucial role in mitigating 
this shortfall. Nostrum in particular, is anticipated to reduce the deficit by approximately 4 bcm  
per annum, providing a significant boost to Kazakhstan’s efforts in addressing the growing gap 
between gas supply and demand. This situation underscores the need for strategic investments and 
initiatives to ensure a stable and sustainable gas supply that meets the country’s increasing energy 
requirements.

Nostrum has a technically 
verified project that is 
self-funded for receiving and 
processing raw gas from the 
Karachaganak field, located 
only 100 km away, which 
currently has its gas re-
injected and exported for 
processing at the Orenburg 
Gas Processing Plant.

In 2023, Nostrum successful 
completion of the re-start of 
its GTU-3. The facility is 
located at the Chinarevskoye 
field, north of Uralsk. 
International and domestic 
pipelines are located near the 
Company’s infrastructure hub, 
enabling safe and efficient 
transportation of all 
processed products.

10%

In 2023, around 10%  
of the production 
capacity of the GTU was 
utilised. The Company 
is actively making 
efforts to attract 
third-party gas to 
unlock its full potential.

4.2bcm

The GTU’s total 
processing capacity  
is 4.2 bcma. Nostrum 
can contribute to 
meeting Kazakhstan’s 
current gas 
requirements.

GRI 2-22, 203-2

Delivering on our promises

2023 has been a 
transformative year for 
Nostrum, marked by 
several key operational 
milestones that 
underscore the efficacy  
of our mixed-asset  
energy strategy.

Arfan Khan
Chief Executive Officer

Last year we successfully completed the 
restructuring of our bonds, leading to  
a strengthened balance sheet and 
safeguarded cash reserves. This financial 
stability enabled us to expand our 
upstream portfolio, notably through the 
acquisition of the Stepnoy Leopard fields 
and commencement of a limited-scale 
drilling program at the Chinarevskoye field. 
In our midstream activities, we achieved  
a major milestone by starting to process 
third-party feedstock in our gas treatment 
facility for the first time. Additionally, we 
realised considerable improvements in  
our ESG risk rating, thereby improving  
our standing in the industry.

These accomplishments were made 
possible by the invaluable support of  
our newly appointed Board of Directors, 
following the successful completion of the 
Group’s bond restructuring in Q1 2023. 

Moving forward we will continue to execute 
the strategic catalysts and priorities as 
agreed with our exceptional Board, with 
razor-sharp focus on controlling costs, 
maintaining operational liquidity, and 
judicious allocation of capital to progress 
value-accreting growth opportunities 
across our upstream and midstream 
portfolios. Nostrum is well-prepared to face 
future challenges and our achievements 
to-date demonstrate our commitment to 
operational excellence and sustainability. 

accomplished by our strategic acquisition 
of an 80% stake in Positive Invest LLP, which 
holds the subsoil use rights to the Stepnoy 
Leopard Fields in the West Kazakhstan. 
Located about 100 km west of our 
world-class 4.2 bcma full-process 
infrastructure, this field represents an 
attractive Nostrum-operated upstream 
tie-back project that could deliver material 
reserves, potentially off-setting the Group’s 
depleting resource base at the 
Chinarevskoye field. 

Strategic pillars in action: 
Upstream achievements
Acquisition of Stepnoy Leopard field
Following last year’s significant milestone, 
the restructuring of our bonds, Nostrum 
has diversified successfully the upstream 
portfolio from a single-asset (Chinarevskoye 
Field) to a multi-asset company. This was 

The Stepnoy Leopard Fields are estimated 
to contain substantial proven undeveloped 
recoverable resources, ranging from 50 to 
150 mmboe, with liquids constituting over 
20%. There are eight laterally stacked 
gas-condensate reservoirs with over 100 
wells drilled during the Soviet era. The 
appraisal operations commenced in Q3 
2023 with a targeted data gathering 

14  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

campaign that includes fluid sampling, 
extended well testing, and capturing 
reservoir properties. The well appraisal 
operations were nearly complete at the 
date of release of this report and significant 
data has been collected that included well 
flow rates, fluid contacts, and fluid and 
reservoir properties across a logged 
interval with c. 50-meter of net-pay. The 
flow-rate and pressure build-up tests 
confirm high well productivity potential 
with peak rate indications of c. 20 mmcfd 
and 600 bcpd in a 3 ½” tubing. We believe 
that the positive results obtained to date 
support the commercial potential of the 
field, hence in March 2024 we made a final 
investment decision (“FID”) for the initial 
field development phase of the Stepnoy 
Leopard Fields with the forecast total 
capital budget of US$100 million gross. The 
forward plan is to compile a Competent 
Person’s Report (CPR) to reclassify specific 
resources into reserves. 

A tie-back project of this scale and 
magnitude will also increase meaningfully 
the utilisation of our 4.2 bcma processing 
facilities, especially when combined with 
the additional production from Ural O&G 
that commenced in Q4 2023. 

Limited-scale drilling programme
Over the past four years, the Chinarevskoye 
field has seen an anticipated annual 
production decline of 24%, owing to the 
natural depletion of our mature primary 
reservoirs. To further evaluate the 
remaining reserves development potential 
we re-processed the 3D seismic and have 
been conducting extensive subsurface 
studies since 2022. This has led to the 
identification of additional drilling 
opportunities that indicate a wide-ranging 
risk/reward characteristics. From this 
opportunity set, we selected two highly 
ranked drilling targets across the primary 
Carboniferous and Devonian producing 
intervals that are also oil-prone and as such 
potentially more robust economically. 
Generally, new drill-wells at Chinarevskoye 
field can cost US$15-20m to drill and 
complete. By utilising existing wellbores to 
either drill deeper or to sidetrack out of, the 

total costs can be reduced by 20% to 30%. 
The two proposed wells although not 
risk-free carry reasonable upside and were 
approved by the Board, with a combined 
estimated costs of US$26m. The first well 
(CHN-301) was spudded in December of 
2023 with drilling in Q1 2024 to total depth 
of 4,980 meters on time and on budget, 
and awaiting completion operations with 
start-up expected mid-2024. It had multiple 
in-fill targets across the Carboniferous and 
Devonian age reservoirs. Hydrocarbons (oil, 
gas-condensate) have been encountered 
across three key intervals. The results are in 
line with our expectations of initial well rates 
of 400 to 700 boepd. The drilling rig will now 
move to well No.41, with expected spud in 
late April and start-up in Q3 2024. This well 
is a sidetrack and carries a higher level of 
geologic risk as it is a step-out from the 
existing well control in the targeted 
Devonian reservoir. If successful, these  
wells will enable a cost-effective means of 
converting the field’s 2P reserves to PDP 
whilst also complying with Zhaikmunai’s  
PSA obligations.

Upstream Operations: with Gas  
lift expansion
The annual average production in 2023 was 
10,091 boepd. The annualised decline of 
24% was greatly improved (by 5-6%) due to 
the successful and safe installation in July of 
the new compressor that nearly doubled 
the total field gas-lift capacity from 500k 
m3/day to 900k m3/day. As stated 
previously, all of the primary producing 
reservoirs have seen rapidly rising water-cut 
whilst also experiencing pressure 
depletion. This causes wells to decline 
faster and die earlier at lower water-cuts 
without some form of downhole assistance 
to lift the heavier fluid column. Gas-lift and 
ESPs are the two main technologies 
employed in the field for this purpose with 
bulk of the wells on gas-lift. The gas-lift 
expansion project has injected a new life 
into the ageing wells and with the help of 
best-in-class well & reservoir management 
is succeeding in slowing the field’s 
production decline by at least 5-6%. 

The upstream operations also safeguarded 
the operational liquidity by controlling 
opex and G&A against continued upward 
supply-chain pressures and inflation whilst 
delivering a solid performance on the 
production system availability of better 
than 98% with under 4% production 
deferment. Further, we completed our 
product exports without any disruptions 
despite the prolonged conflict in Ukraine 
and delivered c. 3.2 mmboe in sales 
volumes. Our netbacks also benefited from 
the new off-take contracts that significantly 
reduced the steep discount to the Urals  
oil benchmark. 

Strategic pillars in action: 
Midstream achievements
Completion of the re-start of GTU-3
The successful commissioning and safe 
restart of our US$750m state-of-the-art 
GTU-3 gas plant has been a significant 
development for Nostrum that underscores 
our commitment to innovation and 
operational excellence. 

Utilising the cutting-edge turbo-expander 
technology, the GTU-3, with its annual 
processing capacity of 2.5 billion cubic 
meters, boasts improved efficiency in the 
extraction of LPG by 15 to 20%. Moreover, 
the plant’s operating turn-down capacity 
threshold has also been further reduced  
via installation of a recirculation system, 
enabling the plant to operate safely at 
much lower production rates. 

Since the third quarter of 2023, GTU-3 has 
been operational with better than 90% 
availability, aligning with design specifications 
and efficiently processing dry gas, LPG, and 
condensate. Together with GTU-1 & 2, we 
are now fully operational with the 4.2 bcma 
processing facilities that will support 
expansion of the midstream business. 

This achievement not only advances our 
position in the energy security but also 
aligns with Kazakhstan’s broader  
energy needs.

STRATEGIC REPORTChief Executive Officer’s statement

Midstream Operations: Start of Ural 
O&G tie-back (Rozhkovskoye Field)
Last year represented a notable 
advancement in Nostrum’s midstream 
strategy, with tie-back of Ural O&G’s 
Rozhkovskoye field and processing the 
first-ever third-party feedstock in our gas 
treatment facility. This development marks 
the beginning of a new phase for our 
operations.

We completed on-time and budget the 
pipeline installation and the associated 
facilities to connect the Rozhkovskoye field 
at our southern manifold. Our project and 
operations teams worked hand-in-hand 
with the Ural O&G project team to achieve 
a safe commissioning and startup, ensuring 
at all times that the minimum safety 
standards related to asset-integrity and 
process-safety are adhered to. Production 
commenced from U-21 well in December 
2023 and continues to ramp-up. The plan is 
to connect additional four wells during 2H 
2024 with combined throughput to reach 
1.5 million m3 per day of raw gas1. Nostrum 
is processing the gas under a processing 
agreement that covers gas, LPG, and 
condensate.

This collaboration with Ural O&G represents 
a pivotal moment for us as we expand the 
utilisation of our world-class treatment 
facilities and position ourselves as a 
preferred partner for handling and 
processing third-party gas in Western 
Kazakhstan. Our state-of-the-art infrastructure 
is designed to process up to 4.2 bcm per 
annum or more of third-party gas, offering 
faster processing solutions at significantly 
reduced costs compared to other 
alternatives. The realisation of the Ural 
O&G tie-back project is a proof-of-concept 
for commercialisation of the stranded 
gas-fields in West Kazakhstan that would 
otherwise not be economic as a stand-
alone development. As such, this presents 
a compelling opportunity to unlock 
additional value for RoK and to drive a rapid 
increase in domestic supply by nearly 20%, 
contributing significantly to Kazakhstan’s 
long-term gasification plan and the 
development of cleaner energy resources.

Karachaganak Tie-Back Studies
We have continued to internally evaluate 
various scenarios of connecting nearby 
fields, including the giant Karachaganak 
gas-condensate field to our 4.2 bcma 
processing facilities. Located c.100 km 
south of our facilities, the Karachaganak 
field with an estimated 60 tcf of gas and 
currently producing c. 18 bcma, remains  
a strategic opportunity for RoK both in 
relation to energy security and transition. 
To maximise the condensate recovery, 
about half the gas produced from the field 
is re-injected and half exported to the 
Orenburg Gas Plant (OGP) in Russia.  
The field’s commerciality is linked to its 
recovery of the liquids via gas re-cycling.  
As is normally the case, the reservoirs 
undergoing gas re-cycling over time will 
begin to dry-out and as such start to 
experience rapidly rising producing gas  
to condensate ratios. We expect the  
field’s overall gas production to increase 
substantially from 18 bcma to perhaps  
30 bcma in the next few years and as such 
substantial additional gas handling 
capacities will be required and Nostrum’s 
processing facilities can be part of this 
solution space. Our state-of-the-art gas 
processing infrastructure offers the fastest 
possible startup solution at the lowest 
possible cost that would benefit both RoK 
and the field’s operator KPO, especially as 
an alternative to increasing supplies to or 
from Russia. 

Strategic pillars in action: ESG 
achievements
Nostrum’s dedication to ESG principles 
continues to be a key focus of our strategy. 
As a prominent employer in the West 
Kazakhstan region, employing over 500 
Kazakh nationals, accounting for more than 
92% of our workforce, we are committed  
to initiatives that foster human capital 
development, combat bribery and 
corruption, and maintain high standards  
in safety, environmental compliance,  
and emissions control.

In 2023, we further strengthened our  
ESG task force and enhanced our ESG Risk 
Rating, securing a favourable position 
within the industry. Our active participation  
in the National ESG Club also reflects our 
commitment to sustainable development 
across Kazakhstan.

As evaluated by Sustainalytics, our ESG  
Risk Rating improved to 30.1 from 40.1 last  
year, transitioning Nostrum to the lower 
spectrum of the “High Risk” category and 
nearing the “Medium Risk” classification  
by a mere 0.1 point. According to the 
Sustainalytics’s rankings, this progress has 
also positioned Nostrum among the top  
20 companies in the Oil & Gas Exploration 
and Production sector.

We remain committed to reducing 
greenhouse gas emissions. Our actual GHG 
emissions in CO2 equivalent were 180,157 
tonnes in 2023, and 6% higher compared  
to 2022. A 22 thousand tonnes of CO2 
equivalent increase in emissions in 2023 is 
due to the re-start of GTU-3 and, as a result, 
higher fuel consumption requirement.

As a company focused primarily on gas, we 
recognise the substantial opportunity to 
support the shift towards a cleaner energy 
mix through the utilisation of our world-
class facilities. We are aligning our strategies 
with Kazakhstan’s extensive gasification 
initiatives, ensuring our position as an 
important contributor to the nation’s 
energy stability. 

HSE
At Nostrum, ensuring the safety and 
well-being of our employees and 
contractors is of paramount importance. 
Our ongoing commitment to occupational 
safety is directed towards achieving zero 
fatalities and significantly reducing the 
Total Recordable Incident Rate (TRIR), Lost 
Time Injury Rate (LTIR), and Road Traffic 
Incidents (RTI). We have upheld an 
exemplary safety record over the past four 
years, with no fatalities reported during our 
operations. However, I regret to report a 
tragic incident in 2023 where we lost a 
contractor employee. The incident occured 
during steady-state operations and routine 
maintenance. The worker who was 
conducting thermo-insulation of equipment, 
fell into an opening where a functional 
guardrail was missing, from a height of  
10 meters, sustaining injuries which 
unfortunately proved fatal. This loss is 
deeply felt and serves as a stark reminder 
of the criticality of fostering continuously 
safety as a core value. Following this 
incident, we conducted thorough 
investigations and have taken further 
measures to strengthen our occupational 
safety rules and oversight, specifically in 
relation to the strict adherence to our 
“Permit to Work” system. 

1. According to Ural O&G guidance.

16  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

The entire senior leadership team remains 
engaged at the grass-root level, placing a 
high priority on winning hearts & minds, 
and helping to promote a mindset of 
continuous improvement in the journey  
to achieving our collective goal of zero 
incidents. 

Our efforts succeeded with tangible results 
in other ratios, as evidenced by a 52%  
y-o-y decline in the TRIR and zero RTI, 
highlighting our continuous commitment  
to safety improvements, active leadership 
engagement, and fostering a culture  
where incident reporting and proactive 
intervention are encouraged and rewarded. 
HSE is a critical element of our strategic and 
operational focus, consistently driving me 
and my team to maintain the highest safety 
standards.

Our financial performance
The financial performance of the Group in 
2023 remained relatively buoyant owing to 
improved production performance from 
the gas-lift expansion, tight cost controls, 
and improved net-backs under new off-take 
agreements. However, despite all efforts to 
improve top-line revenue and margins, the 
revenues decreased year-on-year by 40% 
due to the continued field-level production 
declines of the mature Chinarevskoye field, 
in combination with lower average Brent 
prices from US$100.9/bbl to US$82.5/bbl. 
Consequently, our EBITDA fell to US$42m, 
with an EBITDA margin of 35.2%, reflecting 
the impact of reduced revenues against a 
largely fixed cost structure.

In 2023, with the exceptional focus on 
controlling costs and improving efficiencies 
across all facets of our business Nostrum 
managed to generate US$23m in positive 
operating cash flow before payments of 
around US$25m taxes and penalties as a 
result of tax audit of previous years. Such 
cash generation was sufficient to cover 
capital expenditures and most of the 
coupon payments during the year. 
However, non-recurring items of US$25m 
paid on completion of the bond restructuring 
and US$19.3m payment for 80% stake in 
Positive Invest LLP, together with tax audit 
payments led to decrease in our cash 
balances to US$161.7m from US$233.6m.

Looking ahead, the Company will need  
to tap into its existing cash reserves for 
potential investments in new projects  
and activities, such as the appraisal and 
development at the Stepnoy Leopard  
fields or the drilling program at the 
Chinarevskoye field. Nevertheless, cost 
optimisation will remain a critical focus to 
preserve our cash reserves for the growth-
oriented programs. While we kept our opex 
and G&A expenses under control, we  
are also committed to minimising cost 
increases necessary for the development  
of new projects like Stepnoy Leopard and 
Ural O&G, by reallocating and efficiently 
utilising our existing resources. 

We are diligently working on capital 
allocation to ensure the strategic 
development of our opportunity funnel, 
aiming for maximsing return on investment. 
The progression and financial requirements 
of the Stepnoy Leopard field will significantly 
influence our investment strategy, 
determining whether we can self-fund  
or need to seek additional investments,  
all while maintaining liquidity.

Conclusion 
I extend my sincere gratitude to the entire 
Nostrum team. Despite the challenges 
faced by our company and the broader oil 
and gas sector, we have continued to 
deliver on our promises.

As we transition into 2024, I am enthusiastic 
about the future, the forthcoming 
opportunities, and have great confidence 
in our resiliency in facing the challenges 
head-on. Nostrum is poised to advance 
its strategic objectives, contributing to 
regional development, supporting 
Kazakhstan’s energy transition, and 
enhancing value for our investors and 
stakeholders.

In closing, I would like to convey my sincere 
appreciation for the continuous trust and 
support from our investors, the relentless 
commitment of our employees, and the 
productive engagement by all our partners. 
Your collective commitment forms the 
foundation of our success.

alongside meeting our financial 
obligations and compliance with 
bond covenants, stands at the 
forefront of Nostrum’s agenda. 
Engagement with our stakeholders, 
including minority shareholders, is 
crucial for their understanding of 
Nostrum’s plans to monetise its 
infrastructure. Further financing 
capital injection might be required 
if Nostrum is to be successful in 
those plans.

•  In February 2023 Nostrum completed the 
implementation of the restructuring after 
obtaining all required licenses and approvals. 
As a result, US$1.125bn of existing notes have 
been replaced with US$250m Senior Secured 
and US$345m Senior Unsecured notes due in 
2026. The remaining portion of existing notes 
were converted into the Company’s equity 
and the existing ordinary shareholders were 
diluted to 11.11%, subject to further dilution if 
the warrants held by existing noteholders  
are exercised.

•  Regular update and disclosure around results 
including conference calls and press releases 
as and when required.

•  Financial reports and extensive other 

shareholder information, including Russian 
translations of all press releases, are available 
on our website.

•  Our Annual General Meeting provides an 
opportunity for all shareholders, including 
minority shareholders, to ask questions of  
the Board.

•  In March 2023, Nostrum’s Board and senior 
management team held a Capital Markets 
Day in London to update investors and 
shareholders on the strategy and the 
Company’s performance following the 
completion of the restructuring.

Local communities

Nostrum co-exists with diverse communities in 

Kazakhstan, and we try to strengthen community 

engagement and promote long-term development in 

the areas immediately surrounding our operations.

•  To successfully co-exist with the 

communities within which Nostrum 
operates, we need to understand 
what is important to them and how 
we are able to contribute.

Suppliers and contractors

We are committed to building sustainable 

relationships with our suppliers, contractors  

and customers.

Governments and regulators

Governments and regulators set the framework 

within which we operate and changes to policies, 

regulations, legislation and personnel can have  

major impacts on the Group’s business.

•  Our suppliers must meet high 

safety, legal and ethical standards.

•  We recognise our role as a leading 

contributor to the local and 
national economy, therefore we 
continue to engage local suppliers 
to meet our operating needs.

•  A number of the Board’s decisions 

require careful consideration  
of governmental and/or  
regulatory issues.

•  We pay substantial amounts of 
taxes and social contributions.

Throughout 2023, the Company actively 
interacted with the local community. During 
2023, sponsorship and charitable assistance 
was provided to various public associations and 
local communities. The Company’s support in 
2023 is evidenced by the following:

•  Construction of a park and planting fruit trees 

in the town of Beles.

•  Providing funds for repair and improvement 
of material and technical base for general 
education schools and preschool institutions, 
purchase of school supplies for children from 
large families and low-income families.

•  Providing financial assistance to young 

athletes and winners of various intellectual 
academic competitions to participate in 
international competitions and contests. 

•  Acquisition of medical rehabilitation trainers 

for Daryinsk Social Services Center, charitable 
assistance to Disabled People Society.

•  Allocation of funds for children requiring 

treatment outside of Kazakhstan.

•  Financial support in organisation of the 

regional contest of the best health 
professionals of West Kazakhstan region.

•  Providing support on an as-needed basis to 
the region we operate in, such as preventing 
natural disasters during severe weather 
conditions (blizzards, snowfalls, floods) by 
providing special machinery and equipment.

•  Where commercially attractive, contracts 
were extended ensuring continuation of 
relationships and building further on raising 
HSE and operating standards.

•  In some cases, contract scopes were split to 

maintain relationships with the service 
providers, in particular in relation to new 
construction projects.

•  Formal and informal discussions are held  
on a regular basis with local and national 
government, regulatory and tax officials and 
ministers across a variety of levels within 
Nostrum. In this way we can be aware of  
and responsive to proposed changes in 
legislation or the interpretation of existing 
laws and regulations.

•  With the completion of restructuring in early 
2023, the Company is now well-positioned to 
move expeditiously to unlock the full 
potential and value of its existing world-class 
gas processing infrastructure, acting in the 
best interest of our investors and other 
stakeholders, whilst strengthening the  
energy security of the region.

Our key performance 
indicators provide a 
balanced set of metrics that 
emphasise both financial 
and non-financial measures. 
These assist the Board in 
evaluating our Company's 
performance.

Financial KPIs
Whilst Nostrum has successfully 
built infrastructure and produced 
over 100 mmboe from the 
Chinarevskoye field, it has 
incurred substantial debt and 
faces declining production from 
its producing field. In 2023 the 
Group has restructured its debt 
and reinforced its tight financial 
discipline to maintain liquidity 
and safeguard our core business.

Cash and cash equivalents 
decreased in 2023 mainly due  
to payments associated with 
completion of the Restructuring, 
tax audit payments and 
acquisition of Stepnoy  
Leopard fields.

Increases in Opex and G&A 
expenses in 2023 were necessary 
for enabling growth opportunities 
such as Ural O&G processing, 
Stepnoy Leopard appraisal and 
project development. On a per 
barrel basis these costs also 
increased due to the decline  
in production volumes.

Selling and transportation costs 
decreased on a per barrel basis 
following the changes in offtake 
agreements and delivery 
destinations.

Non-financial KPIs
Performing responsibly and 
safely is integral to our strategy 
and to the sustainability of our 
business. We believe that long- 
term value comes from seeing 
success as a part of a bigger 
picture, encompassing people 
and the environment. We have 
set ourselves specific non- 
financial KPIs to track our 
progress, as we believe this to 
be the best way to monitor our 
achievements in relation to 
environmental, social and 
governance matters. In 2023, 
Nostrum ESG KPI targets were:
•  Reduce GHG emissions 
with 5% of 2022 actual 
CO2 equivalent level. 

•  HSE KPIs:

•  Achievement of the 

approved 2022 HSE Plan 
(provided that there have 
been no fatalities).

2023 developments

Production in 2023 was 10,091 boepd, which represents a 
23.5% decline compared to 2022, and slightly higher than 
expectations, mainly because of the successful project 
implementation of additional gas-lift. Chinarevskoye field 
average daily production for 2024 is forecast to be in the 
range of 7,000-8,000 boepd.

Drilling and workover operations 
at the Chinarevskoye Field
In August 2023, the Company’s Board of 
Directors approved a limited-scale drilling 
programme for the Chinarevskoye field to 
be executed over 2023-2024, in line with 
the license commitments and field 
development plan of the Company’s 
subsidiary Zhaikmunai LLP. The programme 
will leverage existing wellbores to reduce 
costs and carries a level of uncertainties 
and risks as the planned subsurface targets 
contain multiple exploration, appraisal,  
and development objectives.

The total rig workover campaign in 2023 
consisted of 5 interventions on a range  
of horizons for oil and gas-condensate 
wells. As in 2022, rigless re-completions, 
additional perforations and acid stimulations 
were also carried out on a number of oil, 
gas-condensate and water-injection wells. 
Gaslift was successfully introduced in gas 
condensate wells allowing continuation of 
production and additional candidates will 
be targeted in 2024. 

As noted in the Reserves section,  
extraction of 2P volumes will require further 
interventions (side-tracks, new drilling and 
workovers) up to 2026. More workover 
activities are planned in 2024 with drilling 
operations re-commenced in 2023 as it  
was planned. However, execution of the 
programme to recover the 2P reserves  
is dependent on Nostrum successfully 
identifying low risk drilling targets, and  
to this end seismic and geological work  
is ongoing. There is no guarantee that 
Nostrum will be able to achieve such 
de-risking, which could have a material 
impact on Nostrum’s ability to develop the 
remaining Proven and Probable Reserves 
at Chinarevskoye.

In 2023 the uptime of the processing 
facilities was 99.2% for oil and 99.7% for  
gas processing. Planned downtime of the 
plant was 75% lower than expected with 
maintenance of oil treatment plant causing 

a three-day and 20K boe of deferred 
production. Unplanned plant downtime, 
primarily due to a fire in the 10KV 
substation, was less than a day and a 
deferment totaling 12K boe. The autumn 
compressor maintenance incurred only a 
7K boe deferment with no plant shut down. 

As of 31 December 2023, the Company  
had 44 production (28 oil and 16 gas 
condensate) wells in operation in the 
Chinarevskoye field.

Completion of the re-start  
of GTU 3
In September 2023, Nostrum announced 
the successful completion of the re-start  
of its c.$750 million state-of-the-art GTU-3 
gas plant, with 2.5 billion cubic metres  
per annum gas processing capacity. The 
Company completed the modifications  
and other works on GTU-3 subsequent to 
its commissioning and start-up in 2019.  
The plant employs cutting-edge turbo-
expander technology enabling improved 
efficiency in the extraction of LPG; the 
upgrades also reduced the plant operating 
turndown requirements. GTU-3 is 
operating as per design and delivering  
dry gas, LPG, and condensate to sales 
specifications.

Acquisition of Stepnoy  
Leopard fields
In July 2023, Nostrum acquired an 80% 
interest in Positive Invest LLP, which holds 
the subsoil right for the Stepnoy Leopard 
fields in the West Kazakhstan region. 
Zhaikmunai LLP was assigned as operator 
for the field.

The acquisition price was US$20 million 
(less a modest amount of debt owed to 
Nostrum Oil & Gas Coöperatief U.A.). 
Management estimates that the Stepnoy 
Leopard Fields hold between 50 mmboe 
and 150 mmboe of recoverable volumes 
which are considered contingent resources, 
with over 20% estimated to be liquids. 

There are eight fields covered by the 
licenses with over 100 wells drilled in  
the Soviet era which have confirmed 
hydrocarbons to be present. The resources 
are considered by management to be 
contingent due to the appraisal and 
development risks, noting the fields have 
not previously been developed in part  
due to the lack of needed infrastructure.

In September 2023 the Company 
commenced appraisal campaign at the 
Stepnoy Leopard fields to re-enter two 
existing wells in the Teplovskoye reservoir 
to take representative fluid samples and 
conduct extended well testing. In 2024,  
the well appraisal operations are nearly 
complete and the FID made for the initial 
field development phase.

Additional third-party volumes
Start-up of Ural O&G tie-back and  
first gas to Chinarevskoye gas 
treatment facility
The core strategy for Nostrum to  
create value for its stakeholders is to 
commercialise the investment made in  
its infrastructure, the focus being on 
filling the spare capacity with third-party 
hydrocarbons. A significant milestone in  
this strategy was reached in 2023 with the 
initiation of the Ural Oil & Gas LLP (Ural 
O&G) tie-back project.

Agreements were signed in 2018 with Ural 
O&G for processing their hydrocarbons at 
Nostrum's Chinarevskoye gas processing 
facility. The partnership focused on 
leveraging spare capacity and tapping  
into Ural O&G's Rozhkovskoye field,  
which is situated less than 20 km from  
the Chinarevskoye field.

Ural O&G’s Rozhkovskoye field production 
start was achieved safely with one well 
(U-21), with the remaining planned four 
wells to commence in 2024. The system is 
currently utilising a temporary line and a 
three-phase separator for measurement. 
During 2024, a permanent line with fiscal 
metering unit will be installed by Ural O&G 
as per contract.

Ural O&G, is a company owned by 
KazMunaiGas (KMG) (50%), Sinopec  
(27.5%) and MOL Group (MOL) (22.5%).

Nostrum is also focused on entering into 
additional agreements which can fill all  
the remaining capacity at its GTF.

Reserves

The Chinarevskoye field (Chinarevskoye)  
is the only producing field owned by the 
Group. Its governing PSA dates from 1997  
and the licence is valid until the end of 
2031. Initial hydrocarbon discoveries at 
Chinarevskoye were made during the 
Soviet era. There have been 103 wells and 
side-tracks drilled under the PSA between 
2004 and 2023. The licence is 100% owned 
by Zhaikmunai, the Group’s principal 
Kazakhstan operating company.

Chinarevskoye is a multi-layer structure with 
17 reservoirs and 53 compartments spread 
over three areas. Commercial hydrocarbons 
have been found in the Lower Permian, 
Bashkirian, Bobrikovski, Tournaisian, 
Frasnian, Mullinski, Ardatovski, and 
Biyski-Afoninski reservoirs.

Group management provided an estimate 
of the Chinarevskoye Proven, Probable and 
Possible reserves as of 31 December 2023, 
which was internally prepared under the 
guidelines set forth in the 2018 Petroleum 
Resources Management System (SPE-
PRMS) and was not subject to an external 
audit as no material change in the reserves 
development was made. The internal 
reserves estimation workflow covered 
volumes of reserves, production and 
discounted future net income estimated  
by management.

Production and future net income were 
derived from a drilling and well intervention 
program to extract the estimated Proven, 
Probable and Possible reserves at a 
long-term Brent benchmark average oil 
price of US$75 for 2024 and US$70 from 
2025 onwards. However, execution of the 
program to recover the 2P reserves is 
dependent on Nostrum successfully further 
identifying low risk drilling targets, and to 
this end seismic and geological work is 
ongoing. There is no guarantee that the 
Group will be able to achieve this, which 
could have a material impact on the 
Group’s ability to develop the remaining 
Proven and Probable Reserves at 
Chinarevskoye.

Total 2P (Proven plus Probable) reserves are 
23.2 mmboe as of 31 December 2023 after 
adjusting for reservoir production of 
3.7 mmboe in 2023. The net reduction in 
reserves of 1.4 mmboe in the year is due to 
poorer-than-expected production from the 
Biyski- Afoninski North-East and Ardatovski 
North-East gas reserves but being partially 
offset by better production associated from 
other producing horizons and the 2023 
workover and rigless intervention 
campaign. The Proven and Probable 

reserves volume requires 14 CAPEX 
interventions, with an additional 11  
OPEX well interventions for production 
maintenance (2022: 28.3 mmboe  
requiring 17 CAPEX interventions).

Management’s estimates of reserves of  
31st December 2023 and a comparison 
with the reserves of 31st December 2022 
are summarised in Table 1. Please refer to 
page 135 for more details on estimation 
uncertainties.

The Total 1P (Proven) reserves for 
Chinarevskoye at December 31st 2023 was 
16.3 mmboe or 3.9 mmboe down year-on- 
year due to 2023 production and poorer 
than expected performance in the 
Biyski-Afoninski North-East and Ardatovski 
North-East gas condensate reservoir which 
was partially offset by a positive revision in 
other reservoirs due to well performance 
and successful workovers and rigless 
interventions. 1P reserves volumes are 
comprised of 15.1 mmboe for Proven, 
Developed Producing (PDP) from 44 
current wells and 1.2 mmboe for the 
Proven, Undeveloped (PUD) category 
which assumes the deepening of one well, 
the sidetracking of another and one 
workover.

The current Probable Undeveloped case 
assumes 9 rig-assisted interventions 
including four workover recompletions, 
side-tracking of four existing wells, and  
one new vertical well in the Bashkirian 
reservoir. After a three-year break, which 
was bridged with a targeted well workover 
and rigless well intervention program to 
offset some of the field production decline, 
the Company started a two-well drilling 
program in December 2023 to be executed 
over 2023-2024.

In 2024, Nostrum plans to continue this 
workover and well intervention programme 
by targeting a limited number of reserves 
development wells along with production 
maintenance, and continue the drilling 
programme. This programme, together 
with the 44 existing producers, cover the 
estimated 2P reserves as at 31 December 
2023. It should also be noted that there  
has been some decrease in volumes in 
undeveloped reservoirs associated with 
delays in the re-start of the drilling 
campaign.

Possible reserves of 8.2 mmboe as at  
31 December 2023 (2022: 8.5 mmboe) are 
attributed to lower declines than the Proven 
and Probable cases in existing producers 
and 10 well interventions (3 WO, 5 
sidetracks, 2 new wells).

Table 2 shows the breakdown of each 
reserves category by products.

Reserves by reservoir
The breakdown by reservoir is given in 
Table 3. A summary and comparison of the 
workover and drilling programme by 
reservoir is given in Table 4.

Biyski-Afoninski North-East
2P reserves are estimated at 7.15 mmboe, 
down 2.75 mmboe compared to 2022-year 
end (9.9 mmboe) which includes 
1.4 mmboe of production in 2023 and a 
1.35 mmboe negative revision due to 
observed gas production performance 
in 2023.

Gas lift was introduced into 4 more wells  
in 2023 to maintain production with 
increasing water-gas ratio and a further  
2 wells are planned in 2024, predominantly 
through low cost rigless interventions and 
using the expanded Gas lift system 
commissioned in July 2023.

Probable and Possible Developed volumes 
are attributed to existing producing  
wells, with lower declines interpreted 
respectively. No new drilling is planned in 
this reservoir. The 2019 Schlumberger study 
concluded that the potential of further infill 
drilling is limited, which corresponds with 
management’s opinion. 

Tournaisian North-East, West  
and South
The Tournaisian North-East has a total 2P of 
8.5 mmboe at 2023-year end, representing 
a 1.3 mmboe decline year-on year, including 
1.26 mmboe production and a 0.05 mmboe 
negative revision to reflect recent well 
performance.

Proven Undeveloped volumes are 
associated with one deepening and one 
sidetrack well in 2024-2025 whilst Probable 
Undeveloped Reserves are associated  
with one idle well workover in 2024, one 
sidetrack producer in 2026, one water-flood 
sidetrack in 2026 and two workover 
recompletions for the extension of  
the water-flood in 2025. Production 
maintenance workovers are planned  
in the reservoir in the years up to and 
including 2027.

Tournaisian West 2P is 0.34 mmboe despite 
0.11 mmboe production as the well Ch-204 
was connected to GL in the second half of 
2023 showing stabilised production 
performance.

In the Tournaisian South, there are limited 
PDP volumes associated with the three 
remaining producers and Possible reserves 
associated with one new well planned  
for 2026.

Ardatovski North-East and South
Proven Producing volumes are associated 
with three current producers. One Probable 
Undeveloped side-track well is planned  
for the Ardatovski North-East reservoir in  
2026. No further reserves development is 
planned for the Ardatovski South reservoir, 
beyond the current producer.

Frasnian North
2P reserves are estimated at 1.51 mmboe  
at year end 2023, despite 0.21 mmboe of 
production in 2023; the better than 
expected well performance is reflected in 
the slight reserves increase by 0.08 mmboe 
of the existing producer Ch-40_1. Probable 
Undeveloped reserves being attributed to 
well Ch- 41_1_1, with a drilling start in Q2 
2024 and expected to be online before  
end of 2024.

The development plan still foresees three 
additional Possible Undeveloped side-
tracks planned for 2025-2026, depending 
on the success of Ch-41_1_1, which the 
geological model is expected to confirm.

Mullinski North-East, North  
and South
Proven Developed Producing reserves 
remain for three wells, two in the North- 
East and one in the North respectively. 
Proven Undeveloped volumes are 
attributed to one new well in the North-East 
block and planned for drilling in 2024.

Two Possible Undeveloped category well 
locations have been identified in the 
North-East block and are side-tracks of 
existing wells, while one new Possible well 
is planned for drilling in the Mullinski South. 
All three wells are planned for 2025-2026.

Bashkirian North-East & West
PDP reserves remain for two wells 
produced via Electric Submersible Pumps 
(ESPs). One Probable Undeveloped new 
vertical well is proposed in the Bashkirian 
North-East from 2026.

Filippovski
Five low-cost workover recompletions (one 
Probable and four Possible) have been 
identified for the Filippovski reservoir. 
These are planned, subject to further 
technical and economic evaluation, to  
be carried out in 2025-2026.

Oil Treatment unit (OTU)

With the re-start of GTU 3, 
complementing the previous  
gas processing trains, we have 
built a world-class infrastructure 
processing hub that is currently 
under-utilised but with the 
potential to support the 
production and sale of billions  
of cubic meters of gas in north-
western Kazakhstan for years  
to come.

Oil Treatment Facility
The oil treatment facility (OTF) has a 
maximum throughput capacity of 400,000 
tons per annum. The OTF associated 
infrastructure includes a gas-lift facility that 
was commissioned in 2015 and a liquid 
hydrocarbons pumping station transferring 
crude oil and stabilised condensate via the 
liquids pipeline to the rail loading terminal. 

In 2023, 1.039 mmboe of oil and 0.692 
mmboe of condensate was transferred 
through the pipeline. After the installation 
and commissioning of an additional gas lift 
compressor in 2023, a total of up to 
950,000 cubic meters of recycled lift-gas 
per day has been compressed and made 
available to enhance oil production, with 
modifications to the existing system.

Raw Gas Treatment Facility
The gas treatment facility (GTF) is designed 
to treat raw gas from gas condensate 
reservoirs (and the associated gas coming 
from the OTF) into condensate, LPG and 
dry gas with a by-product of granulated 
sulphur. The gas treatment facility includes 
three gas treatment units (GTU1,2 & 3) 
which have the capacity to treat 4.2 billion 
cubic meters of raw gas per annum.

In mid-2023, GTU 3 was started again after 
the turbo expander re-installation, 
modifications on the hot oil system and 
installation of a gas re-circulation system 
ensuring sufficient feedstock. The 3rd train 

was used to process the raw gas for the 
remainder of 2023 and demonstrated 
functionality and efficiency with higher-
than-expected LPG yields.

Low-pressure system
A low-pressure system has been installed  
to facilitate the reduction of the GTF inlet 
pressure from 42 to 8 bar, so as to prolong 
the run-life of wells, primarily gas-
condensate. Installed capacity of gas 
compression is 48,000 standard cubic 
meters per hour in total with 19 wells 
flowing through the low-pressure system  
as of the end of 2023.

Gas lift system 
In 2023 we upgraded the gas lift system by 
adding a 3rd gas lift compressor, doubling 
the capacity from 27,000 to 54,000 
standard cubic meters per hour. Currently, 
the compressors are running at 40,000 
standard cubic meters per hour, limited  
by total gas lift system constraints which 
require further de-bottlenecking.

Power generation plant
The gas-fired power generation plant is 
linked to the GTF and has an electrical 
power output capacity of 26 MW. The 
generated capacity of the plant is sufficient 
to meet the existing and the maximum 
future need. Backup generation capacity  
of up to 15 megawatts is available at the 
processing facilities.

Storage facilities
Nostrum has over 35,000 cubic meters of 
storage capacity for liquids at its field site 
and rail loading terminal.

Gas pipeline
Nostrum has its own 17 km dry gas pipeline 
which is linked to the Orenburg-Novopskov 
gas pipeline. The pipeline has sufficient 
capacity to export the entire GTF maximum 
production capacity dry gas volumes.

Liquids pipeline
Nostrum has its own 120 km liquids 
pipeline that runs from the field to the 
Company’s rail loading terminal in Beles 
(near Uralsk). The pipeline has a maximum 
daily throughput capacity of 3,500 t/d.

Rail Loading Terminal
Nostrum has its own automated rail loading 
terminal at Beles, located near the city of 
Uralsk, that receives all produced crude oil 
and condensate and has a daily capacity  
of 5,000 t/d.

KTO pipeline connection
Nostrum has constructed a secondary 
crude oil pipeline to enable export sales 
from its rail loading terminal via the 
Atyrau-Samara export pipeline operated by 
KazTransOil (KTO). The connection to the 
KTO pipeline has enhanced the Company’s 
ability to maximise crude oil netbacks 
through the commodity cycle.

Sulphur Recovery Unit and Incinerator 
In 2023, modifications commenced on the 
Sulphur Recovery Unit to handle higher 
H2S levels, necessary for processing 
third-party gas like UOG. This enables H2S 
processing using either the direct oxidation 
or Claus process. These modifications are 
expected to be completed in 1Q 2024.

During 2023 facility inspection, serious 
cracks at various heights of the 62-meter 
incinerator chimney were identified, 
necessitating urgent repair. After evaluating 
several repair options, the only HSE 
acceptable method was building 
scaffolding. Expert consultation supported 
this methodology and design was 
approved. While installing the scaffolding 
at 33 meters, two damaged scaffolding 
poles led to a suspension of work. Support 
to continue the work was obtained with 
confirmation that the structure remains 
within the safe operating range that was 
assessed by an independent expert 
inspector in the first quarter of 2024.

STRATEGIC REPORTRisk management

Risk management

The Group has a system of internal controls consisting of its governance framework, 
segregation of authorities and duties, various policies and procedures, training, supervision 
and internal communications as well as monitoring by senior management and the 
Board of the planning and decision-making processes. The risk management system is 
embedded in these components of the system of internal controls in order to identify, 
manage and report on the relevant risks that may impact achievement of the Group’s 
strategic objectives,and ensure compliance with applicable regulatory requirements.

Risk management framework
The Board, supported by the Audit 
Committee and senior management,  
has ultimate responsibility for risk 
management and internal control, including 
responsibility for the determination of the 
nature and extent of the principal risks it is 
willing to accept to achieve its strategic 
objectives, and for ensuring that an 
appropriate risk-awareness culture has 
been embedded throughout the Group.

Operational day-to-day risks are inherent  
in the various business functions and 
processes of the Group. These are 
categorised as business function risks and 
are identified and managed by the relevant 
staff and managers in the course of their 
activities to ensure safety, compliance,  
and efficiency. The members of the  
Senior Management Team have overall 
responsibility for managing such business 
function risks aggregated at the level of 
their functional responsibility, but can 
delegate such responsibilities to their direct 
reports. At the highest level the identified 
risks are aggregated and categorised into 
the following categories of principal risks 
and uncertainties: strategic, operational, 
financial, compliance and other, which are 
respectively managed and monitored at 
Board level.

Based on risk registers, related analysis and 
discussions, senior management and the 
Board periodically review previously 
identified significant risks, update their 
understanding of the likelihood of 
occurrence and potential impact, and 
identify potential new significant risks. 
These significant risks are discussed in 
more detail below in the Principal Risks 
and Uncertainties section.

In 2023, the processes related to risk 
management and internal control systems 
were consistent with the UK Corporate 
Governance Code and FRC Guidance on 
Risk Management, Internal Control and 
Related Financial and Business Reporting 
issued in September 2014. The Board  
and Audit Committee are aware of the 
additional requirements related to the  
risk management and internal control 
framework as set out in the UK  
Corporate Governance Code 2024.

During 2023 the Group did not have a 
dedicated internal audit function, as was 
the case for the past few years where the 
Group has relied on third party audits  
and ad-hoc audits/process reviews 
performed by employees and overseen  
by management with results reported into 
the relevant Board committee. The Board 
and Audit Committee obtain assurance  
on the effectiveness of the internal control 
framework through: (a) upholding a regular, 
detailed and timely system of internal 
operational and financial reporting against 
key performance targets, historical trends 
and industry norms and the investigation  
of any material deviations or failures, (b) 
obtaining independent expert opinions 
on matters of importance, including  
any changes or disputes in the legal or 
regulatory environment, (c) visits to  
the company’s place of operations in 
Kazakhstan and enquiries of local staff  
and management, (d) reinforcement of  
the internal system of Whistleblowing, (e) 
evaluating all material investment policies 
and proposals, and (f) seeking external 
professional advice on the company’s risk 
register and Board assurance framework. 

Following the end of 2023, the Board 
continues to monitor closely internal control 
over financial reporting and the related party 
identification and disclosure processes. More 
detailed information on the Whistleblowing 
Policy and Workforce representation can be 
found on pages 62-63.

Environmental, social and 
governance (ESG) matters
ESG matters form an integral part of the 
areas covered by the Group’s systems of 
risk management and internal controls, and 
the Board recognises their significance and 
importance. Identified ESG risks and 
related responses can be seen within 
Operational, Climate Change and Other 
risks in the “Principal risks and uncertainties” 
disclosure on pages 34-38.

The Board receives appropriate information 
for managing such risks. Management is 
responsible for ensuring that systems of risk 
management and internal control are in 
place to effectively manage and monitor 
energy risks and other ESG matters. More 
detailed disclosure on the established 
policies and procedures in these areas  
can be found on pages 50-81.

Changes from prior-year  
risk assessment
In 2023, the principal risks and uncertainties 
managed and monitored by the Board and 
senior management included most of the 
risks for 2022 and for which the related risk 
assessments did not change significantly.

Principal risks and uncertainties GRI 201-2, 205-1

Risk management

Nostrum’s Senior Management Team is pro-actively engaged with key 
stakeholders among state authorities to address and resolve any potential issues at 
early stages. In addition, the Group endeavours to identify legislative changes at 
early stages before their introduction and to the extent possible participate in the 
relevant working groups engaged in development of such changes.

To mitigate geopolitical, regional and customer risks, the Group continues to 
strengthen customer relationships through establishing long-term off-take 
agreements whilst also looking at possibilities to geographically diversify its 
customer portfolio.

The Group has implemented robust internal controls and procedures to ensure 
compliance with international sanctions on Russian and Belarus individuals, 
organisations and supplies of goods and services, including the evaluation of 
counterparties and their banks, contract procedures, and liaising with external 
legal advisers. The Group regularly updates lists of all persons/entities and 
products sanctioned in order to ensure Nostrum does not enter into transactions 
with any sanctioned persons or entities.

The Group quarterly revisits the product price assumptions used in its short-term, 
medium-term and long-term financial models, and performs stress testing of such 
forecasts to fluctuations in product prices and these are monitored by senior 
management and the Board.

The Group continues to take prudent actions to protect liquidity, including 
identifying reductions in operating costs, general and administrative, and selling 
and transportation costs that could be implemented without having a negative 
impact on production or operations in the going concern period.

Senior management constantly monitors the Group’s exposure to foreign currency 
exchange rate changes and makes plans for necessary measures. In addition, the 
Group maintains its relationships with multiple financial institutions should it need 
to implement commodity price hedging contracts. No such contracts were 
entered into in 2023.

Description of risk

Strategic risks
Geopolitical factors

The Group’s operations are exposed to risks associated with the 
political and business environment in Kazakhstan, being the Group’s 
sole country of commercial operations, as well as its neighbouring 
countries.

Nostrum has historically benefited from its geo-strategic position in 
the heart of an export corridor between Russia and markets to the 
west of the Caspian, however, the Group remains exposed to the risks 
of the ongoing economic and political impact on Russia of its actions 
in Ukraine, being reliant on its transport routes and ports. Ongoing 
severe sanctions and trade restrictions imposed by, among others, 
the US, UK and EU on Russia, have increased the economic and 
political uncertainty and may have a material adverse impact on the 
Group’s business, results of operations, financial condition and 
prospects.

Product price volatilities

The Group’s operations and financial performance are exposed to 
changes in the market prices for its products driven by external 
business and political factors, which are outside the Group’s control.

Oil and gas prices are subject to volatility due to a variety of factors 
beyond the Group’s control. Factors affecting crude oil prices include 
supply and demand fundamentals, economic outlooks, production 
quotas set by OPEC and political events. 

Since the domestic selling price of dry gas is directly dependent on 
the price of crude oil and the price of oil is volatile, the Company 
could also face volatility in the price of dry gas. Also, the Group  
could be compelled by governmental authorities, purportedly acting 
based on RoK legislation, to sell its oil, condensate, LPG and gas 
domestically at prices determined by the RoK Government, which 
could be significantly lower than prices which the Group could 
otherwise achieve.

Lower oil and gas prices may reduce the economic viability of the 
Group’s operations and proposed operations and materially 
adversely affect its business, results of operations, financial  
condition and prospects. In particular, the Group’s ability to produce 
economically from the Chinarevskoye Field or any prospective fields 
will be determined, in large part, by the difference between the 
revenue received for its products and the operating costs, taxation 
costs, royalties and costs incurred in transporting and selling those 
products.

Risk management

Filling the spare gas processing capacity 

The Chinarevskoye field is a mature declining asset with a proved  
and probable reserves base at a level that will produce volumes of 
hydrocarbons including raw gas sufficient to utilise less than 15 
percent of capacity available at the Group’s gas treatment facilities, 
which have a combined 4.2 billion cubic meters capacity per annum. 
At the end of 2023, Ural OG production came onstream from its 
Rozhkovskoye field, increasing the capacity utilisation to 30 percent. 
The plan is to increase even more with connecting additional wells 
from Ural OG. The agreement for the purchase of gas and processing 
of condensate from the Rozhkovskoye field is for a period of four years.

The Company is therefore reliant on acquiring and developing 
nearby assets with significant resource potential and/or processing 
third party gas through its processing facilities to continue to produce 
free cash flows and build sufficient cash reserves to repay future 
indebtedness. The ability to negotiate and secure these strategic 
acquisitions is highly uncertain and the ability to fund the development 
of such projects, the costs of which may be substantial and require 
external funding, may not materialise.

Oil and gas exploration and production activities are capital intensive 
and subject to financing limitations and inherent uncertainty in their 
outcome. Further, significant expenditure is required to establish the 
extent of oil and gas reserves through seismic re-processing and 
mapping, other surveys as well as drilling. Therefore, there can be  
no certainty that further commercial quantities of oil and gas will be 
discovered at Chinarevskoye or acquired by the Group to enable it 
to utilise the spare capacity in its treatment facilities.

Operational risks
Oil and gas reserves and production

Estimating the value and quantity of economically recoverable oil and 
natural gas reserves and resources, and consequently the rates of 
production, necessarily depend upon a number of variables and 
assumptions, such as ultimate reserves recovery, interpretation of 
geological and geophysical data, marketability of oil and gas, future 
product prices, operating costs, development and production costs 
and workover and remedial costs, all of which may vary from actual 
results, which would affect the Group’s financial performance and 
achievement of strategic objectives. The re-classifications of 
significant amounts of reserves from 2P to contingent resources  
in 2020-2021 were the result of crystallising of such risks.

Even if the Group is able to discover or acquire commercial quantities 
of oil and gas in the future, there can be no assurance that these will 
be commercially developed. Appraisal and development activities 
involving the drilling of wells across a field may be unpredictable and 
may not result in the outcome planned, targeted or predicted, as only 
by extensive testing can the properties of an entire field be more fully 
understood.

Finally, given that the Chinarevskoye reservoir is a mature and 
declining asset, the Group has been actively performing well 
workover and interventions to reduce the rate of decline of the 
reservoirs. In addition the Group has also started its drilling campaign 
in December 2023. The initial campaign is for drilling 2 wells (301 
deepening and 41 sidetrack) as part of the SA20 obligations. Such 
activities, as well as construction, operation and maintenance of 
surface facilities, are subject to various risks, including the availability 
of adequate services, technologies and expertise, which may 
adversely affect the fulfillment of the Group’s strategic objectives.

From the end of 2019, the Board came to the conclusion that diversification of its 
sources of feed stock to the processing facilities would provide the Group with an 
opportunity to gain from expanding the use of available capacities, technological 
resources and human capital, and ultimately benefit from its under-utilised 
infrastructure.

The GTU 3 plant was upgraded and made ready for receiving future gas. The 
Sulphur Recovery Unit upgrade will be completed by May 2024 allowing treatment 
of different concentrations of H2S.

The Group continues to actively engage in discussions with other third parties 
interested in supplying raw gas to completely fill its spare processing capacity.

In July 2023, Nostrum acquired an 80% interest in Positive Invest LLP, which holds 
the subsoil use right to the Stepnoy Leopard Fields in the West Kazakhstan region 
for US$20m. Management estimates its recoverable volumes between 50 mmboe 
and 150 mmboe which are considered to be contingent resources. In September 
2023 the Company commenced appraisal campaign at the Stepnoy Leopard fields 
to re-enter two existing wells in the Teplovskoye reservoir to take representative 
fluid samples and conduct extended well testing.

Also, the Group has a number of additional area-wide opportunities under review 
that may serve to strengthen the Group’s upstream and midstream portfolio in the 
coming years.

The Group has a department of geologists and reservoir engineers who perform 
periodic assessments of its oil and gas reserves in accordance with international 
standards on reserve estimations and prepare production forecasting using 
advanced exploration risk and resource assessment systems. The results of the 
assessments are audited periodically by the Group’s independent reserves 
consultant, Ryder Scott.

For drilling and well workover activities, the Group engages skilled personnel  
and leading service suppliers, as well as employing internationally accredited 
operations and cost monitoring systems, based on which management oversees 
the work progress. The Group continued its well workover and intervention 
programme in 2023 to minimise the production decline and this will be continued 
in 2024 as the field gets older and equipment requiring more regular maintenance. 
The gas lift expansion project, requiring an additional compressor to increase lift 
gas availability for both oil and gas condensate wells was successfully completed 
during 2023 and more than doubled the capacity to support the producing oil and 
gas condensate wells, accelerating production.

Maintenance of wells and surface facilities is scheduled in advance, in accordance 
with technical requirements, and all necessary preparations are performed in  
a timely manner ensuring a high quality of work. In addition, the Group has 
emergency response and disaster recovery plans in place and periodically 
conducts necessary training and testing procedures.

STRATEGIC REPORTRisk management

Principal risks and uncertainties continued

Description of risk

Cybersecurity risks

Nostrum may be vulnerable to the unauthorised or inappropriate 
access to data, or the unlawful use, disclosure, disruption, deletion, 
corruption, modification, inspection, recording, or devaluation of 
information. Such cybersecurity failures may significantly adversely 
affect the Group’s operations and financial results through 
disruptions, shutdowns and delays in production and other activities.

Risk management

The Group uses a number of dashboards such as MS Secure and MS Compliance, 
which monitor security and compliance, and also help to identify areas where 
security might be enhanced. At the start of employment each new employee is 
briefed on the Group’s Information Security Policy and signs a confidentiality 
agreement. All mailboxes and data are placed on Microsoft servers with 
appropriate levels of protection. Passwords have complexity requirement and 
double authorisation has been introduced for most users. All data traffic, servers 
and computers are subject to scanning and protection by anti-virus software. 
Physical access to data storage is restricted to authorised personnel.

Environmental, Social and Governance risks
Risks of incidents, including risk of explosion

The Group’s operations are subject to hazards and risks common in 
its industry, including encountering unusual or unexpected rock 
formations or geological pressures, fires, explosions or power 
shortages, equipment failures or accidents, premature declines in 
reservoirs, blowouts, uncontrollable flows of oil, gas or well fluids,  
or water cut levels, pollution and other environmental risks.

The Group’s QHSE policies are periodically revised to ensure compliance with 
changes and new requirements in this area. Periodic training on the requirements 
of policies and regulations is held for employees. Nostrum’s operations are based 
on the five QHSE pillars: HSE leadership; rigorous incident investigation; process 
safety-critical elements identified and maintained; contractor HSE management; 
and environment and climate change.

Failure to prevent or adequately mitigate these hazards can have  
a broad range of results, including, but not limited to, injury of 
employees or local residents, a partial or total shutdown of 
operations, significant damage to equipment, suspension or 
withdrawal of licenses and relevant sanctions. Any of the above  
could materially and adversely affect the Group’s business, results  
of operations, financial condition and prospects.

It should also be noted that the legal framework for operational  
safety is not yet fully developed in Kazakhstan and given the changing 
nature of environmental regulations, there is a risk that the Group  
will not be in full compliance with all such regulations at all times.

Governance risks

Nostrum must adhere to UK corporate governance and reporting 
requirements. Governance risk factors are usually related to board 
composition and structure, executive remuneration, internal controls 
and risk management framework, corporate policies and procedures, 
risks of corruption and bribery, and others.

Lack of adequate controls and policies, or a failure of those to operate 
effectively, could lead to loss of company resources, non-compliance 
with regulations, and respective significant fines, penalties, as well as 
reputational damage.

Monthly QHSE reports are issued to communicate HSE performance. Management 
KPIs include lost time injury frequency, road traffic injury frequency, total recordable 
injury frequency and numbers of Hazard Observation Cards submitted as well as 
managing reduction of GHG emissions from our operations.

Through the system of Hazard Observation Cards, employees and contractors 
report any unsafe conditions observed in the workplace, which helps to ensure 
their awareness of safe working conditions at all times. All incidents are 
investigated, their causes identified and corrective action plans developed.

There is a classification of equipment as critical or non-critical. Safety critical 
elements are devices, equipment or systems that are required to ensure process 
conditions are maintained within safe operating limits, or the purpose of which is  
to prevent malfunctioning. For example, devices are installed at well-sites to 
automatically close the wells in the case of shutdown, preventing blow-down  
by flaring.

Contractor HSE performance is managed by identifying and mitigating risks, 
setting HSE performance criteria, monitoring, auditing and reporting HSE 
performance, and subsequently using this information for continuous 
development and feedback into the process of contractor selection.

As described on pages 90-92, the Group has established a robust governance 
framework which covers all aspects of the Group’s activities through respective 
Board committees and functional teams under senior management. Although the 
composition of the Board and its committees was not ideal during the reporting 
period due to the transition period, compensating controls and procedures were 
put in place such as additional scrutiny over the Board decisions and more 
frequent Board meetings.

The corporate governance framework is supported by an extensive range of 
policies and procedures covering division of responsibilities, bribery, corruption 
and whistle-blowing, anti-facilitation of tax evasion, as described on page 92 and 
various other policies and practices related to social and environmental matters 
described across other section of the report. Such policies and procedures are 
designed and implemented to ensure that all required compliance obligations  
are met.

Description of risk

Environmental risks

Risk management

The Group’s operations are subject to environmental risks inherent  
in oil and gas exploration and production industries. Examples of 
environmental risks include risks stemming from more intense extreme 
weather events, rising energy intensity in the oil and gas industry,  
the changing regulatory landscape, the risk of fugitive emissions  
and climate change policies driving down demand.

Compliance with environmental regulations may make it necessary for 
the Group, at substantial cost, to undertake measures in connection 
with the storage, handling, transportation, treatment or disposal of 
hazardous materials and waste and the remediation of contamination.

In addition, the legal framework for environmental protection and 
operational safety is not yet fully developed in Kazakhstan. Stricter 
environmental requirements may be adopted in the near future,  
and the environmental authorities may move towards a stricter 
interpretation of existing legislation. The costs associated with 
compliance with such regulations could have a material adverse  
effect on the Group’s business, results of operations, financial 
condition and prospects.

Climate change risks
Climate change

Continued attention to climate change issues by governments, 
investors and customers and relevant developments in laws and 
regulations, investor and customer preferences may have significant 
adverse impact on the Group’s business.

New requirements, laws, policies and regulations may result in 
substantial additional expenditures on capital construction, 
compliance, operations and maintenance. The level of expenditure 
required to comply with these laws and regulations is uncertain.

In addition, any perceived weakness in environment related policies, 
procedures and efforts, sub-optimal assessment by an ESG rating 
agency and comparison to peers, might adversely impact the Group’s 
access to capital markets, reduce ability to raise additional financing, 
increase financing costs and have a negative impact on the Group’s 
business plans and financial performance.

Compliance risks
Subsoil use agreements

As the Group performs exploration, development and production 
activities in accordance with related licenses for the oil and gas fields, 
there are related risks that the Group might not be able to obtain 
extensions or agree amendments to the field development plan, 
when necessary, risks of non-compliance with the licence 
requirements owing to ambiguities, risks of alteration of the licence 
terms by the authorities and others. These risks may result in the 
Group’s inability to fulfil scheduled activities; fines, penalties, 
suspension or termination of licenses by authorities; and, 
respectively, significant and adverse impact on the Group’s  
business, financial performance and prospects.

Compliance with laws and regulations

The Group carries out its activities in a number of jurisdictions and, 
therefore, must comply with a range of laws and regulations, which 
exposes the Group to the respective risks of non-compliance. In 
addition, the Group must comply with the Listing Rules, the Disclosure 
Guidance and Transparency Rules, FRC guidance and requirements, 
as well as requirements in connection with its restructured debt,  
in light of its publicly traded shares and notes. Hence, there are 
non-compliance risks, including reputational, litigation and 
government sanction risks, to which the Group is exposed.

The impact of these risks may vary in magnitude and include 
regulatory actions, fines and penalties by authorities, diversion  
of management time, and may have an overall adverse effect on  
the Group’s performance and activities towards achieving its  
strategic objectives.

The Group actively plans and manages projects designed to mitigate certain 
environment-related risks. Limiting GHG emissions is a management KPI.

The Group’s operations continuously put effort and commitment into improving 
energy efficiency, reducing flaring, venting and leaks, and monitoring and 
effectively managing emissions and waste. Also, the Group has recently started 
recycling utilised water at the campsite.

The Senior Management Team actively evaluates opportunities to further adapt 
and implement cost-effective mitigation measures.

The HSE and ESG Committees currently have responsibility for Environmental 
related matters.

In 2023 Company developed Energy management policy and Energy Efficiency 
Improvement Plan, HSE policy and QHSE Management System have been revised 
as well.

The Group is actively planning and managing projects designed to mitigate 
certain climate change related risks. For instance:
•  To decrease its exposure to rising fuel prices, drilling rigs have been retooled  

to derive more power from electricity rather than diesel;

•  In operations there is a permanent effort and commitment to improve energy 

efficiency and to reduce flaring, venting and leaks; and

•  At campsite most of the water the Group utilises now is recycled.

Climate change is on the Board’s agenda. The Senior Management Team actively 
evaluates opportunities to further adapt and implement cost- effective mitigation 
measures.

The Group has procedures and processes in place for the timely application for 
extension of licence periods or for amendments to the field development plan, 
when it is considered appropriate however, uncertainty remains in relation to 
timing and results of decisions of authorities. The Group maintains an open 
dialogue with RoK governmental authorities regarding its subsoil use agreement. 
In the event of non-compliance with a provision of the agreement, the Group 
endeavours to have such terms modified and pays any penalties and fines that  
may apply.

For the purpose of effective corporate governance and compliance with laws, 
regulations and rules, the Group has adopted a number of policies and 
procedures, as mentioned above. The Group also performs periodic updates 
based on the changes in regulatory requirements and carries out related 
communications and training for employees.

Necessary communication lines are established with authorities to ensure timely 
and adequate inbound and outbound flow of information. Management and the 
Board monitor significant matters related to legal and compliance matters in order 
to act promptly in response to any actions. In addition, management maintains  
an open dialogue with its sponsors in relation to any matter related to non-compliance 
with Listing Rules and other regulatory requirements.

STRATEGIC REPORTRisk management

Principal risks and uncertainties continued

Description of risk

Financial risks
Liquidity risks

Forecasting to maintain an adequate liquidity position is subject to the 
risk that inaccurate information or assumptions are used for forecasts, 
and to risks of counter-party delay or a counter-party's failure to meet 
their contractual obligations owing to severe market conditions.

Moreover, the Group’s current and planned expenditures are subject 
to unexpected problems, costs and delays, and the economic results 
and actual costs may differ significantly from the Group’s current 
estimates. Prices for the materials and services the Group depends 
on to conduct and expand its business may increase to levels that no 
longer enable the Group to operate profitably.

All the above factors in combination with a significant negative 
movement in world energy prices could result in the Group’s liquidity 
position becoming more strained than the severe but plausible 
downside scenario in the Going Concern assessment.

Refinancing risks

The Group’s Notes will mature in June 2026 and, in the absence of 
support from any of the strategic initiatives described on pages 18-19, 
there is a risk that the Group will require partial or full refinancing of 
SSNs, and repay SUNs in specie through the issuance of new shares 
(further diluting the existing ordinary shareholders at the time) or have 
their maturity extended through another refinancing or restructuring 
exercise. 

Tax risks and uncertainties

The uncertainty of application, including retroactive application,  
of tax laws and the evolution of tax laws in Kazakhstan create risks 
related to additional tax liabilities from assessments and risks related 
to the recoverability of tax assets.

Kazakhstan’s tax legislation and regulations are subject to ongoing 
changes and varying interpretations. Instances of inconsistent 
opinions between local, regional, and national tax authorities are  
not unusual. The current regime of penalties and interest related  
to reported and discovered violations of Kazakhstan’s tax laws are 
severe and where the tax authorities disagree with the positions taken 
by the Group the financial outcomes could be material. Fiscal periods 
remain open to review by tax authorities for five calendar years 
preceding the year of review. Under certain circumstances reviews 
may cover longer periods.

Tax risks and uncertainties may adversely affect the Group’s 
profitability, liquidity and planned growth.

Other risks
Other significant risks, including emerging risks

Other risks are those that are not specifically identified within any of 
the principal risks and uncertainties but may be related to several 
such areas or be organisation wide. These include risks related to:
•  Fraudulent activities;
•  The Group’s supply chains;
•  Accounting and reporting management systems; or
•  The availability of human resources.

They may also significantly impact the Group’s financial performance, 
reputation and achievement of its strategic objectives.

Risk management

Management and the Board constantly monitor the Group’s actual and forecast 
liquidity position to ensure that sufficient funds are available to meet any 
commitments as they arise.

In addition, management and the Board assess key financial ratios, sensitivity tests 
of its liquidity position for changes in crude oil price, production volumes and 
timing of completion of various ongoing projects, to understand the resilience of 
the business and to be prepared for taking necessary remedies.

Further efforts are made on cost optimisation to reduce capital expenditures, 
operating costs and general and administration costs.

The Board notes that uncertainty remains related to the Group’s ability to repay/ 
meet its liabilities, including the repayment of its Notes due in 2026 and the risk 
that the Group may require refinancing in 2026.

Relevant considerations were made as part of the viability assessment as described 
on pages 39-40.

The Group has policies and procedures related to various tax assessments and 
positions, as well as other control activities to ensure the timely assessment and 
filing of tax returns, payment of tax obligations and recovery of tax assets.

The Group regularly challenges, either with the RoK tax authorities or through the 
RoK courts, tax assessments that it believes are inapplicable to it, pursuant to the 
terms of either its subsoil use agreements or applicable law.

The Group has an Anti-Bribery and Corruption Policy, and provisions relating to 
the same are included in the Group’s Code of Conduct. Related training and 
updates are periodically provided for employees in relation to their obligations  
in this area.

The Group has a wide range of internal controls over its supply chains and 
accounting and reporting processes, including policies, procedures, segregation 
of duties for authorisation of matters, periodic training for employees and so on. 
The Contracts Board was established to meet weekly to review and approve the 
placement of contracts or expenditures.

Senior management and the Board stay alert to emerging challenges related  
to various management systems and related governance matters and, when 
necessary, initiate change initiatives to ensure enhancement and integration  
of certain management systems.

The risks listed above do not comprise all those associated with the Group’s business and are not set out in any order of priority. 
Additional risks and uncertainties not presently known to management, or currently deemed to be less material, may also have an adverse 
effect on the Group’s business. The risks listed above are continuously monitored by the management team and assessed when making 
business decisions.

Viability statement

Viability statement

Viability assessment
The three-year financial model used as a 
base-case scenario for viability assessment 
assumed following:

•  Production forecasts reflecting 
management’s internal view of 
Chinarevskoye production under a no 
further field activity scenario. This 
production forecast is more conservative 
than that used in the impairment testing 
process (proved and probable reserves 
base used) as the viability assessment 
basis is more akin to the proven 
developed producing reserves base as 
outlined in the Ryder Scott reserves audit 
as of 31 December 2022;

•  Inclusion of throughput processing 

volumes of hydrocarbons from Ural O&G 
based on management’s internal view, 
and no additional utilisation of the spare 
capacity of Gas Treatment Facilities 
despite being a key strategic focus of 
management for the medium-term 
horizon; and

•  Product price assumptions based on a 

Brent oil price of US$70/bbl throughout 
the assessment horizon. This is within the 
range of average broker consensus 
forecasts as at 31 December 2023.

For the purpose of sensitivity testing, 
several principal risks and uncertainties 
were selected (from those described on 
pages 34-38), which were deemed to have 
the highest potential financial impact on 
the Group’s future performance, taking  
into account prior period assessments.  
The effect of those principal risks and 
uncertainties or their combination on the 
base-case scenario were analysed with the 
assumptions as described in the table below.

The Directors also considered severe but 
plausible scenarios where a combination of 
two or three of the risks shown in the table 
below occur together. 

The scenarios took into account the 
availability and likely effectiveness of any 
mitigating actions that might be required  
if the Group was exposed in the medium 
term to downwards volatility and that are in 
place or could be implemented to avoid or 
reduce the impact or occurrence of the 
underlying risks which would realistically  
be available to the Group in such 
circumstances. In considering the likely 
effectiveness of such actions, the 
conclusions of the Board’s regular 
monitoring and review of risk and internal 
control systems were taken into account.

We assessed the future medium-term 
viability of the Group over a period longer 
than 12 months in accordance with 
provision 31 of the UK Corporate 
Governance Code 2018. The viability 
assessment is performed by stress-testing a 
medium-term financial model to the 
principal risks and uncertainties (described 
on pages 34-38) and their combinations. 
The key features of the financial model 
include the following elements of corporate 
planning and modelling process:

•  Medium-term development planning 
based on three-to-four-year financial 
projections, using management’s internal 
estimate of forecast production from the 
Chinarevskoye field, processing 
hydrocarbons from Ural O&G and 
development of Stepnoy Leopard fields. 
No other third-party volumes or strategic 
initiative projects have been included in 
the viability assessment as there is 
currently no certainty that they will arrive 
within the assessment period; and

•  Annual budgeting and forecasting 

process incorporating preparation of an 
annual budget for the following year, 
which is reviewed and approved by the 
Board, and followed up with quarterly 
forecasts, which are monitored by senior 
management and the Board.

Viability time horizon 
Considering the uncertainties inherent to 
the Group’s operations as well as the 
medium-term development planning 
mentioned above, the Board concluded 
that a viability assessment over a three-year 
period to 30 June 2027 provides a robust 
and realistic evaluation of the Group’s 
future performance. With this approach the 
Board continues to believe that the 
assessment:

•  improves the optimal balance between a 
reasonable degree of confidence and an 
appropriate longer-term outlook;

•  is aligned with medium-term 

development planning mentioned above;

•  is consistent with other current and/or 

recent communications (e.g. production 
forecasts etc.); and

•  is appropriate for the current stage of 

development of the Group and gives an 
opportunity to reasonably assess 
sensitivity of the Group’s performance to 
principal risks during the period where 
the Group looks to work on implementing 
its major strategic objectives (described 
on pages 18-19).

NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023  39

STRATEGIC REPORTViability statement

Viability statement continued

Climate-related financial 
disclosure
As part of the viability assessment the 
Directors also performed resilience analysis 
as per the requirements of the Taskforce on 
Climate-related Financial Disclosure 
(“TCFD”). TCFD requires the Directors to 
describe the resilience of the organisation’s 
strategy, taking into consideration different 
climate-related scenarios, including a 2°C 
or lower scenario (TCFD Strategy (c)). 

The Directors chose the Net Zero Emission 
by 2050 Scenario (“NZE Scenario”) 
developed by the International Energy 
Agency as the reference point in 
performing the resilience test and also  
took into account Kazakhstan’s Strategy on 
Achieving Carbon Neutrality by 2060. NZE 
Scenario is aimed at an emissions trajectory 
consistent with keeping the temperature 
rise in 2100 below 1.5 °C (with at least a 
50% probability).

Two key assumptions were taken from NZE 
Scenario for the purpose of severe but 
plausible development scenario for 
stress-testing the company’s resilience:  
1) oil prices projections decreasing to 
US$42 per barrel by 2030; and 2) carbon 
price forecasted at US$25 per tonne of CO2 
by 2030. Please refer to page 79 for  
further details.

The Group maintains sufficient cash 
reserves at the end of the viability period 
when sensitising the base case for the 
above climate-related assumptions. 
Following the assessment, the Directors 
confirm the future strategy and future 
viability remain resilient against the chosen 
climate-related scenario.

Longer term viability
The Directors also considered the viability 
of the business beyond the medium term. 
The Notes issued by the Group will mature 
in June 2026 and, under the base case 
scenario in the current viability assessment 
model, the Directors have a reasonable 
expectation that the Group will be able to 
partially repay the SSNs (US$250m) in 2026, 
and will require refinancing of the remaining 
portion of these notes, and SUNs are 
expected to be either repaid in specie 
through the issuance of new shares (further 
diluting the existing ordinary shareholders 
at the time) or have their maturity extended 
through another refinancing or 
restructuring exercise.

The implementation of the major strategic 
initiatives described on pages 10-13 will 
inevitably support future long-term viability 
of the Group, and the Directors note that 
this may reduce the possible requirement 
for refinancing of a smaller portion of the 
SSN at maturity in 2026 under the base 
case scenario, as noted above.

Viability statement conclusion
Considering the above, the following 
conclusions can be drawn from the viability 
assessment:

•  the Group’s viability conclusion is not 
exposed to plausible downside risks 
arising in isolation relating to the Group’s 
strategy, operations, liquidity or 
compliance;

•  in the event that a combination of any 
three of the four considered plausible 
downside scenarios arise, the Group’s 
may require additional funding to cover 
the capital expenditures required for 
development of Stepnoy Leopard fields;

•  It is not plausible that all four risks would 
arise together, since, in the event of the 
strategic, operational and compliance 
risks manifesting, the Group would take 
mitigating actions to reduce costs and 
manage liquidity and so the likelihood  
of an increase in costs occurring 
concurrently with the other three 
scenarios is considered remote; and

•  Absent support from any of the strategic 
initiatives described on pages 18-19, the 
Group may need to partially refinance the 
SSNs, and either repay the SUNs through 
issuance of equity or extend their 
maturity through refinancing or 
restructuring.

Based on these assessments and other 
matters considered by the Board, the 
Directors confirm that they have a 
reasonable expectation that the Group  
will continue in operation and meet its 
liabilities as they fall due through the 
three-year viability assessment period 
ending 30 June 2027, subject to possible 
necessity for partial refinancing  
or restructuring of its debt.

General note
For the year ended 31 December 2023 
(the “reporting period”), the Group 
recorded a total comprehensive income  
of US$831.7 million, as opposed to 
US$116.9 million total comprehensive  
loss in 2022. The substantial amounts  
of gains followed the completion  
of the Restructuring, and included 
US$769.6 million gain on debt-to-equity 
exchange and US$174.4 million fair value 
adjustment on the recognition of SSNs  
and SUNs. Further details on the 
Restructuring are described on  
pages 48-49 of this report. 

Other than one-off items described above, 
there were also considerable movements in 
operational items of the income statement. 
Notable 40.1% decrease in revenues was  
a combination of 18.2% decrease in  
the average Brent crude oil price and  
a continuing decline in production of  
over 20% from the maturing Chinarevskoye 
field, which was slightly offset by Gaslift 
expansion in mid-2023. Reductions in cost 
of sales (by US$6.5 million), selling and 
transportation expenses (by US$7.6 million) 
and taxes other than income tax (by 
US$5.6 million). These reductions in  
costs were accompanied by a decrease  
in finance costs (by US$20.3 million),  
which was attributed to the restructuring  
of the Notes 2022 and Notes 2025.

The decrease in Group’s revenue by 40.1% 
in 2023 was largely due to 18.2% lower 
average Brent crude oil price (US$100.9/bbl 
in 2022 vs US$82.5/bbl in 2023), which had 
a substantial impact on oil and condensate 
revenues as shown in the table above. 
Another notable driver of decrease in 
revenues was decline in production 
volumes (as shown in the table above), 
largely due to the natural depletion of the 
Chinarevskoye field. However, it should be 
noted that the successful start-up of a new 
compressor has doubled the Gaslift 
capacity, playing a crucial role in slowing 
the production decline from mid-2023. 

The new line in the Group’s revenue 
breakdown showing US$156 thousand for 
2023, marks the first-ever processing of 
third-party hydrocarbons and reflects 
tolling fees earned from treatment of 
condensate from Ural O&G, while relevant 
revenues from sales of gas and LPG  
are combined with revenues from 
Chinarevskoye field production. This new 
revenue stream represents the initial phase 
of collaboration during the last 10 days of 
2023, with further wells commencements 
expected in late 2024. Such diversification 
of Group activities into processing 
third-party feedstock signifies a strategic 
milestone in expanding the utilisation of  
its gas treatment facilities.

Cost of sales for the reporting period 
ended 31 December 2023 decreased by 
7.6% to US$77.6 million (2022: US$84.1 
million). However, on a per barrel of oil 
equivalent (boe) basis, cost of sales rose to 
US$24.0 from US$18.4 in 2022, and 
excluding depreciation, the cost per barrel 
increased to US$11.5 from US$7.1.

The main components of the change in cost 
of sales are:

Depreciation, depletion, and amortisation 
costs decreased by 22.0% to US$40.3 
million for the reporting period (2022: 
US$51.7 million). This decrease is reflective 
of the depletion rate for oil and gas working 
assets which was 21.52% in 2023, slightly 
lower than the 21.73% in 2022. The 
reduction in the depletion expense is 
associated with the decreased depreciable 
asset base, while the depletion rate was 
almost on the same level.

42  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

Well repair and maintenance costs 
increased substantially by 61.0% to 
US$5.0 million (2022: US$3.1 million), 
reflecting the Group’s intensified 
maintenance efforts to sustain well 
productivity.

Repair, maintenance, and other services 
slightly decreased by 1.6% to US$6.5 million 
(2022: US$6.6 million), which includes costs 
associated with the upkeep of the facilities 
and the procurement of spare parts  
and materials. 

Payroll and related taxes increased  
by 18.1% to US$16.7 million  
(2022: US$14.2 million), influenced 
primarily by salary indexation as well  
as foreign exchange rate changes.

Materials and supplies expenses  
increased by 13.6% to US$4.9 million  
(2022: US$4.3 million). This increase is 
primarily due to the expansion of the well 
maintenance program, the commissioning 
of the Gas Treatment Unit 3 (GTU-3), and 
the expansion of the gas lift system. These 
developments have led to an uptick in 
material costs, which has occurred despite 
the overall reduction in production 
volumes.

Transportation services increased by 9.6% 
to US$2.5 million (2022: US$2.3 million), 
due to lower production levels and cost 
optimisation initiatives.

Change in stock had a positive adjustment 
of US$691 thousand, reflecting the 
inventory changes for the year, in contrast 
to a larger positive adjustment in the  
prior period. 

General and administrative expenses 
slightly increased by 14.3% to  
US$13.8 million for the reporting period 
(2022: US$12.1 million). This was primarily 
due to a 14.9% increase in payroll and 
related taxes from US$6.6 million to  
US$7.6 million and a 17.6% increase in 
professional services from US$3.6 million  
to US$4.2 million. These were partly 
counterbalanced by a 26.0% reduction  
in insurance fees, which decreased to 
US$0.4 million (2022: US$0.6 million). 
Business travel costs notably  
increased by 101.4% to US$0.6 million  
(2022: US$0.3 million), reflecting the 
increased activity of the Group. 

Selling and transportation expenses 
Selling and transportation expenses for the 
year ended 31 December 2023 decreased 
by 37.8% to US$12.4 million (2022: US$19.9 
million). The decrease was particularly 
visible in transportation costs going down 
by 42.0% to US$4.9 million, and loading 
and storage costs, which saw a 49.5% 
decrease to US$4.1 million. These 
reductions were largely a result of the 
decrease in volumes sold and the changes 
in contract terms.

Royalties were significantly lower  
by 40.4%, totalling US$4.8 million  
(2022: US$8.1 million), a result of the dual 
impact of declining market prices and 
reduced production volumes.

Government profit share followed this 
downward trend, decreasing by 30.9% to 
US$1.2 million (2022: US$1.7 million), 
aligning with the overall lower revenue  
from hydrocarbon production.

Export customs duty for the year ended 31 December 2023 decreased by 18.6% to 
US$8.2 million (2022: US$10.0 million). This reduction is directly correlated with the  
drop in oil prices over the year, combined with a decrease in production, both of  
which are primary determinants of customs duty calculations.

The combined effect of these factors led to 
a total tax expense, excluding income tax, 
of US$14.2 million, marking a 28.5% decrease 
from the 2022 figure of US$19.8 million.

Finance costs for the reporting period ended 31 December 2023 decreased to US$102.9 
million, which is was a decrease of 16.5% from US$123.1 million in the previous year. This 
was largely driven by 9.7% decrease in interest expense on borrowings to US$95.2 million, 
which is attributed to the reduction in the balance of borrowings but was partially offset by 
higher effective interest rate on SUNs and SSNs relative to the effective interest rate on the 
2022 Notes and 2025 Notes. For further information please refer to Note 14 in the 
consolidated financial statements of the Group.

Other finance costs decreased by 64.8%  
to US$5.9 million, which in the prior year 
included substantial fees incurred by  
the Group in relation to the restructuring 
process. 

The unwinding of discount on amounts  
due to the Government of Kazakhstan  
and on abandonment and site restoration 
provision increased by 39.1% and 259.0%, 
respectively, reflecting the relevant updates 
of discount rates.

Other expenses
Other expenses for the reporting period 
ending 31 December 2023 significantly 
decreased to US$14.7 million (2022: 
US$29.8 million). This substantial reduction 
of approximately 50.8% is primarily due to 
one-off US$13 million tax penalties and 
fines which were incurred in 2022, while 
there were no such significant expenses in 
reporting period of 2023.

Income tax
Income tax expense for the year ended  
31 December 2023 was US$4.7 million, a 
significant reduction from the US$34.7 
million recorded in the previous year. This 
decrease of US$30.0 million is partly due to 
the absence of the prior year’s additional 
accrual of US$12.5 million, which was 
recognised following tax audit and 
reassessments for earlier years. The decline 
in income tax expense also reflects changes 
in deferred tax as a result of change in the 
tax base of property, plant, and equipment 
relative to the IFRS base, influenced by 
different depreciation rates and 
methodologies as well as the Tenge’s 
devaluation against the US Dollar. 

Liquidity and capital resources
During the period under review, Nostrum’s 
principal source of funds was cash from 
operations. Since the start of the 
negotiations on Restructuring, the focus  
of the Group was on preservation of cash 
by optimising the spend on capital 
expenditures and working capital 
requirements. After the completion of the 
restructuring the Group continued tight 
cost control with the goal to maintain 
positive cash flows from operations, and 
started allocating available cash reserves 
into the growth opportunities, which have 
the potential to create value and increase 
stakeholder returns.

Cash Flows

Net cash flows from operating 
activities
Net cash flow from operating activities was 
US$2.2 million negative for the reporting 
period (2022: US$102.2 million) and was 
primarily attributable to: 

•  Income before income tax for the 

reporting period of US$836.3 million 
(2022: loss US$81.8 million), adjusted  
by a non-cash charge for depreciation, 
depletion and amortisation of 
US$40.5 million (2022: US$51.8 million), 
finance costs of US$102.8 million 
(2022: US$123.1 million) and gain  
on debt-to-equity exchange of 
US$769.6 million (2022: nil) together  
with fair value adjustment on recognition 
of debt instruments of US$174.4 million 
(2022: nil). 

44  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

•  US$14.0 million increase in working 
capital (2022: decrease of US$15.5 
million) is mainly attributable to increase 
in trade receivables by US$3.1 million 
(2022: US$5.7 million), increase in 
prepayments and other current assets  
of US$3.6 million (2022: decrease  
by US$5.0 million), and the decrease  
in other accruals and taxes payable by 
US$17.6 million as part of the current 
liabilities (2022: increase US$28.9 million).

•  income tax paid of US$23.0 million (2022: 

US$6.3 million).

Net cash used in investing activities
Net cash used in investing activities for the 
reporting period was US$28.1 million 
(2022: US$15.8 million) due primarily to:

•  Payment of US$19.3 million on acquisition 

of 80% interest in Positive Invest LLP 

(holding rights to Stepnoy Leopard fields) 
and further payments of US$3.6 million 
related two-well appraisal programme; 

•  US13.7 million (2022: US14.8 million) 

capital expenditures on infrastructure 
projects such as Gaslift expansion for 
US$3.8 million (2022: US$5.0 million), 
modifications and capital repairs at 
GTU1-2-3 US$6.4 million (2022:  
3.8 million), as well as payments of 
expenditures related to well workover  
& intervention programme of  
US$1.0 million for the reporting  
period (2022: US$5.0 million).

•  Transfer from restricted cash in the 

amount of US$5.8 million was primarily a 
net result from refund of the escrow 
account in the amount of US$22.8 million 
and placement of US$16.5 million on 
DSRA account in accordance with the 

terms of Restructuring, which was offset 
by transfer of US$0.5 million (2022: 
US$0.6 million) to liquidation fund as 
required by the subsoil use rights for 
abandonment and site restoration 
liabilities of the Group.

•  US$2.7 million (2022: US$0.3 million) 
interest received on current bank 
accounts and term deposits.

Net cash used in financing activities
Net cash used in financing activities during 
the reporting period made up US$41.6 
million (2022: US$17.5 million) and was 
mainly represented by the payment of 
US$31.8 million coupon on SSNs and SUNs 
for 2022 and 2023, and US$9.8 million 
(2022: US$17.5 million) payments of lock-up 
fees on completion of the Restructuring 
and related advisor fees. 

Commitments
Liquidity risk is the risk that the Group will encounter difficulty raising funds to meet commitments associated with its financial liabilities. 
Liquidity requirements are monitored on a regular basis and management seeks to ensure that sufficient funds are available to meet any 
commitments as they arise. The table below summarises the maturity profile of the Group’s financial liabilities as at 31 December 2023

Capital commitments
During the reporting period, Nostrum’s 
cash used in capital expenditures for 
purchase of property, plant and equipment 
(excluding VAT) was approximately US$13.7 
million (2022: US$14.8 million). This mainly 
reflects costs associated with gaslift well 
infrastructure development, modification 
and capital repairs of GTU 1/2/3, other field 
infrastructure development projects and 
well workover and intervention.

The Group has also initiated a two-well 
drilling programme at the Chinarevskoye 
field, with an estimated investment of  
US$26 million. This programme is set to 
enhance production capacities over the 
2024-2025 period. These operational 
improvements are expected to provide a 
more robust production outlook.

Stepnoy Leopard development
In Q1 2024 the Group made a final 
investment decision (“FID”) for the initial 
field development phase of the Stepnoy 
Leopard Fields with first production 
targeted for the end of 2026. During the 
initial development phase, the Company is 
planning to drill four development wells 
across the key reservoirs, targeting 
recoverable resource potential between 30 
mmboe and 50 mmboe. The wells are 
expected to produce raw sour gas and 
liquids with full-well-stream to the 
Company’s Chinarevskoye processing 
facilities via a 120-km multiphase trunkline. 

The forecast total capital budget for this 
initial field development phase is US$100 
million gross. The full amount (including 
20% minority partner carry) is planned to 
be financed from the Company’s own cash 
reserves and forecast project cashflows. 

The project related capital expenditures 
and contractual commitments will 
commence later in 2024 and ramp-up 
gradually over the 3-year execution period 
prior to startup at the end of 2026. Early 
cash generation will also strengthen the 
self-financing capacity and help spur 
further development of the remaining 
resource base.

Dividend policy
The Group currently pays no dividend and 
has not done so since 2015, as the Board 
determined it was not in the Company’s 
best interests to do so. This will be reviewed 
annually by the Board.

STRATEGIC REPORTFinancial review

Financial review continued

Going concern 
The Group monitors on an ongoing basis 
its liquidity position, near-term forecasts, 
and key financial ratios to ensure that 
sufficient funds are available to meet its 
commitments as they arise and liabilities as 
they fall due. The Group reforecasts its 
rolling 24-month cashflows on a quarterly 
basis and stress tests its future liquidity 
position for changes in product prices, 
production volumes, costs and other 
significant events. Whilst looking for new 
opportunities to fill the spare capacity of 
the Group’s infrastructure, the Directors are 
also focused on a range of actions aimed at 
improving the liquidity outlook in the 
near-term. These include the ongoing 
efforts on further cost optimisation to 
reduce capital expenditures, operating 
costs and general and administration cost.

The Directors’ going concern assessment is 
supported by future cash flow forecasts for 
the going concern period to 30 June 2025. 
The Group had unrestricted cash balances 
of over US$162 million as at 31 December 
2023 and over $16 million in DSRA account. 
The base case going concern assessment 
reflects production forecasts consistent 

Alternative performance 
measures
In the discussion of the Group’s reported 
operating results, alternative performance 
measures (APMs) are presented to provide 
readers with additional financial 
information that is regularly reviewed by 
management to assess the financial 
performance or financial health of the 
Group or is useful to investors and 
stakeholders to assess the Group’s 
performance and position.

However, this additional information 
presented is not uniformly defined by all 
companies including those in the Group’s 
industry. Accordingly, it may not be 
comparable with similarly titled measures 
and disclosures by other companies. 
Certain information presented is derived 
from amounts calculated in accordance 
with IFRS but is not itself an expressly 
permitted IFRS measure. Such measures 
should not be viewed in isolation or as an 
alternative to the equivalent IFRS measure.

with the Board approved plans and 
published guidance and assumes a Brent 
oil price of $75/bbl. Also, the forecast 
investing cashflows take into account 
two-well drilling programme at the 
Chinarevskoye field with total cost of  
US$26 million and initial capital 
expenditures related to development of 
Stepnoy Leopard fields. Under the base 
case going concern assessment to the 
period to 30 June 2025, the Group is 
forecast to have total cash reserves of over 
U$$130 million. The base case scenario has 
also been tested for sensitivity against the 
key assumptions including 10% reduction 
in product prices, 10% reduction in forecast 
production and sales volumes, 10% 
increase in capital expenditures and 
operating cost over the period of 
assessment and unexpected fines and 
penalties by regulators, consistent with the 
sensitivities applied for viability assessment 
as described on pages 39-40. Considering 
such sensitivity analysis conclusion was 
made that the Group is not exposed to 
downside volatility of these key 
assumptions individually or in aggregate.

After careful consideration, the Directors 
have a reasonable expectation that the 
Group and Company have sufficient 
resources to continue in operation for the 
going concern period to 30 June 2025. For 
these reasons, in accordance with provision 
30 of the UK Corporate Governance Code 
2018, the Directors consider it appropriate 
to adopt the going concern basis of 
accounting in preparing the financial 
statements. Accordingly, the consolidated 
financial statements accompanying this 
report do not include any adjustments to 
the carrying amount or classification of 
assets and liabilities that would result if the 
Group were unable to continue as a going 
concern.

Notwithstanding that the going concern 
period has been defined as the period to 
30 June 2025, the Directors have 
considered events and conditions beyond 
the period of assessment which may cast 
doubt on the Group’s ability to continue as 
a going concern. The Directors draw 
attention to the Viability Statement on 
pages 39-40 which highlights a potential 
necessity in the future for partial or full 
refinancing or restructuring of the Group’s 
debt.

EBITDA
EBITDA is defined as the results of 
operating activities before depreciation 
and amortisation, share-based 
compensation, fair value gains and losses 
on derivative instruments, foreign 
exchange losses, finance costs, finance 
income, non-core income or expenses and 
taxes, and includes any cash proceeds 
received or paid out from hedging activity. 
This metric is relevant as it allows 
management to assess the operating 
performance of the Group in absence of 
exceptional and non-cash items.

Operating costs
Operating costs are the cost of sales less 
depreciation and change in stock. This 
metric is relevant as it allows management 
to see the cost base of the Company on a 
cash basis.

To coordinate all processes related to ESG, 
the Senior Management level specialised 
committees have been established within 
the Company – the ESG Committee and the 
HSE Committee, overseen by the CEO and 
led by the Head of ESG and Group Head of 
HSE, respectively, to engage on ESG issues 
with all the stakeholders. These committees 
define Nostrum’s ambitions and vision in 
the ESG domain, monitor the Company’s 
compliance with national and international 
standards, and address the requirements  
of external stakeholders. Both have 
responsibility for the HSE and ESG-related 
matters including the execution of HSE and 
ESG-related targets and projects which fall 
under all material ESG topics of the 
Company.

In order to enact the principle of senior 
management engagement in sustainable 
development management issues, key 
performance indicators (KPIs) were 
sanctioned specifically pertaining to  
ESG performance. See page 23.

1. The increase in GHG emissions is due to re-start of GTU 3 in 2H 2023.

At Nostrum, we annually report on our 
sustainability performance using 
internationally recognised reporting 
standards and frameworks. Our reporting 
follows guidelines, indicators, and 
terminology established by prominent 
organisations such as TCFD, IPIECA, and 
the Global Reporting Initiative (GRI) 
Standards 2021. 

Furthermore, we consistently provide data 
to CDP for climate change and water 
security assessments, and engage with 
Sustainalytics for evaluations of our ESG 
performance and ratings. This report has 
been meticulously prepared with reference 
to the Global Reporting Initiative (GRI) 

Standards 2021.

Management of Material Topics 
In order to ensure that our ESG reporting 
aligns with the concerns that are of greatest 
importance to our stakeholders, we 
conduct routine assessments of materiality. 
The insights gained from these assessments 
serve as the foundation for shaping our 
ESG reporting.

We have identified seven key ESG material 
topics that we consider essential for 
implementing our strategy. The material 
topics assessment helped identify and 
prioritise the reporting topics about our 
business as it relates to ESG. Following  

the principle of double materiality, to  
reflect both the impact of sustainable 
development on the organisation  
and the impact of the organisation on 
sustainable development, these are 
subjects that could have a substantial 
influence on either our financial and 
operational performance or on the 
societies and ecosystems in the regions 
where we conduct our activities. Material 
ESG topics directly translate into ESG  
risks for our organisation.

ESG Management
Management of ESG material topics and 
the integration of the ESG agenda into  
the Company’s activities are significant 
elements of Nostrum’s corporate 
governance system.

Promoting sustainable development 
practices within the Company not only  
aids in adapting to the strategic landscape, 
addressing market changes, and enhancing 
risk management efficiency but also 
cultivates a corporate culture that is 
motivating and innovation-oriented.  
This, in turn, facilitates the establishment  
of positive relationships with stakeholders.

For the effective integration of sustainable 
development principles across all areas of 
activity at Nostrum, more than 20 internal 
documents have been adopted.

ESG ranking
In 2023, Nostrum once again received  
an ESG Risk Rating from Sustainalytics. 
Covering more than 16,000 companies, 
Morningstar Sustainalytics has the widest 
coverage of analyst-based ESG Risk Ratings 
in the market. The Sustainalytics ESG Risk 
Ratings measure a company’s exposure to 
industry-specific material ESG risks and 
how well a company is managing those 
risks. Company ratings are categorised 
across five risk levels: negligible (below  
10 points), low (10-20 points), medium 
(20-30 points), high (30-40 points), and 
severe (above 40 points).

The updated ESG Risk Rating for Nostrum 
by Sustainalytics stands at 30.1 points, 
placing us in the high-risk zone and on the 
brink of transitioning to the medium-risk 
category. The previous ESG Risk Rating in 
2022 was 40.5 points, placing us in the 
severe risk category according to 
Sustainalytics’ methodology. Our efforts 
throughout 2023 to improve ESG risk 
management have yielded significant 
results, reflected in a notable improvement 
in the Company’s rating.

We would like to highlight the following 
rating outcomes:

Our exposure to ESG risks remains high, 
considering the industry, geographical 
factors, and other conditions under which 
we operate – scoring 73.2 points. This 
surpasses the average susceptibility to risks 
of Oil & Gas Producers peers, which stands 
at 69.9 points. Furthermore, our ESG risk 
management grade is also very high at 
Nostrum, significantly outperforming our 
market cap peers in risk management. 
Specifically, Nostrum’s ESG risk management 
level is rated at 69.6 points, categorised as 
Strong Management compared to our 
market cap peers with scores of 22 points 
or below, indicating Weak Management.

We rank at the 10th percentile among  
oil & gas producers in the Sustainalytics 
universe. The majority of companies in the 
Oil & Gas Producers Industry have ESG Risk 
Ratings categorised as Severe, scoring  
40 points or higher.

The most significant improvements in 2023 
regarding the rating are observed around 
the following material topics: Emissions, 

Effluents and Waste, Community Relations, 
Carbon – Own Operations, Land Use and 
Biodiversity, and Resource Use.

Several processes have been enhanced 
within the company, including Environmental 
Policy, Environmental Management System, 
Biodiversity Programmes, Effluent 
Management, Emergency Response 
Programme, Non-GHG Air Emissions 
Programmes, Water Management 
Programmes, Political Involvement Policy, 
Diversity Programmes, Human Capital 
Development, Human Rights Programme, 
and Community Development & 
Involvement Programmes.

Our company has not recorded any 
controversy events or allegations, while the 
most frequent event categories among our 
peers in the Oil & Gas Producers Industry 
are Business Ethics, Emissions, Effluents 
and Waste, Occupational Health and 
Safety, and Community Relations.

ESG risk rating significantly improved
In 2023 we continued to enhance our ESG task  
force and have made significant strides in improving  
our ESG Risk Rating. Our current ESG Risk Rating  
is 30.1, placing Nostrum at the lower end of the  
“High Risk” category, with a minimal difference  
of 0.1 point separating us from being classified  
as “Medium Risk” on the ESG risk rating scale.

Health and safety

At Nostrum, our safety and environmental 
practices are based on four key pillars: HSE 
leadership, incident investigation, process 
safety and asset integrity, and contractor 
HSE management. Each pillar is fundamental 
to maintaining a safe, secure, and 
environmentally aware workplace. HSE 
leadership blends safety into every level  
of our company, while rigorous incident 
investigation enables us to learn from past 
experiences and continuously improve  
our processes.

Process safety keeps our operations  
safe, while effective contractor HSE 
management aligns everyone with our 
safety values. These pillars form the 
foundation of our comprehensive approach 
to HSE, reflecting our dedication to 
upholding the highest standards of safety, 
health, and environmental stewardship.

Beyond these, we enforce “Golden Rules”, 
provide extensive straining on safety 
practices and apply a comprehensive 
Governance framework as outlined in the 
TCFD Governance recommendations on 
pages 75-76.

GRI 403-2

Incidence rates  
and investigation
In 2023, our Total Recordable Incidents 
Frequency rate dropped to 0.75 per million 
man hours, a 52% decrease from 2022.  
The Lost Time Incidents Frequency rate  
was 0.37, and there were no Road Traffic 
Incidents in 2023 for both Nostrum and  
our contractors’ operations.

Regrettably, we experienced a contractor 
fatality in a height-related incident. Prior to 
this, we had maintained a record of five years 
without any fatalities. We undertook 
comprehensive investigation and 
implemented measures to avoid such 
incidents in the future.

Nostrum notes that its activities are 
potentially hazardous. The Group’s 
management, employees and contractors 
are trained to understand that no accidents 
are inevitable as we strive to inculcate an 
environment in which safety consciousness 
and mitigating actions are such that zero 
incidents are possible and achievable.  
For all incidents, we follow our incident 
investigation procedure based on the  
“five whys” and “why tree” methodology  
to determine the root causes and apply 
SMART principles to mitigate future risks.

GRI 2-8

Contractors
We require our contractors and suppliers  
to work to the same high standards as our 
employees, therefore effective contractor 
selection, communication and training in 
our safety culture and practices as well as 
strong monitoring are essential to maintain 
the high level of safety embraced by 
Nostrum.

In 2023, we continued with our contractor 
HSE management implementation and 
performed twelve external contractor HSE 
management audits to test compliance  
with our HSE management system.

Nostrum seeks to promote safe behaviour 
among its contractors and has established 
a wide range of methods to ensure that 
operations at facilities are carried out in full 
compliance with local legislation as well as 
Nostrum rules and regulations. In addition 
to the measures already discussed, 
Nostrum continues to use the hazard 
observation cards initiative introduced in 
2019 (described more fully on page 57). 

The safety of our employees and 
contractors is a top priority for 
Nostrum, and we are dedicated 
to upholding the highest 
international health and safety 
regulations. We aim to foster  
a strong culture of safety 
throughout our operations  
every day.

Safety Culture
At Nostrum, fostering a strong safety 
culture is essential for the well-being  
of our employees, the efficiency of our 
operations, and the integrity of our  
brand. Prioritising safety underscores our 
dedication to ensuring a secure and  
healthy workplace for all stakeholders. This 
commitment not only minimises workplace 
accidents and injuries but also builds trust 
and confidence within our team. Moreover, 
adopting a safety culture contributes  
to increased productivity, reduced 
operational expenses, and a boost in 
overall morale. In essence, cultivating and 
upholding a comprehensive safety culture 
signifies our unwavering commitment to 
employee welfare and business 
sustainability.

STRATEGIC REPORT  
ESG review

Health and safety continued

Our annual contractor HSE forum 
dedicated to Road Safety Rules compliance 
was held in October 2023. General 
directors and HSE Representatives from 
main contractors gathered to discuss  
their HSE performance results with the 
Company’s management. This year, we 
focused on HSE Golden rules and Road 
Safety compliance. The forum allowed  
for open discussions aiming to boost  
our shared dedication to a safe work 
environment. We are committed to 
ongoing dialogue and support to improve 
our HSE practices and achieve the highest 
standards of safety for all individuals 
involved in our operations.

In order to effectively manage the  
“Golden Rules”, Nostrum applies rigorous 
consequence management which means 
that we take a risk-based approach to guide 
people and leaders through the processes 
required when they witness or have 
reported to them inappropriate behaviour 
in the workplace. For serious violations  
of safety rules, staff and contractors risk 
immediate dismissal. For that purpose, 
consequence management is split into  
two categories. The more serious category 
which results in immediate dismissal is 
applied in case of alcohol/drug abuse.  
Less severe cases, such as safety belt 
violation, result initially in a warning 
followed by dismissal if a repeat violation 
is observed.

Golden Rules 
1.  Seatbelts must always be worn by  
the driver and all passengers.

2.  Do not exceed the speed limit and 
reduce speed for impaired road 
conditions.

3.  Do not use phones or operate devices 

while operating a motor vehicle

4.  Alcohol and drugs of any kind 

(excluding approved medicines)  
are forbidden.

5.  Where required, work with a valid permit

6.  Obtain authorisation before entering  

a confined space.

7.  Confirm that hazardous energy sources 
have been isolated, enclosed and 
tagged.

8.  Obtain authorisation before overriding 

or disabling safety controls.

9.  Never walk under a suspended load

10.  Protect yourself against a fall when 

working at heights.

In our operations there are several stages 
to ensure contractor compliance with HSE 
spanning from pre-contract award to 
contract close-out with significant roles  
for the contract owner, contract holder, 
contracts and procurement and HSE staff.

This process is more fully described below:

Pre-Award 
Stage 1 – Vendor Qualification 
To be a qualified bidder, vendors must 
meet our qualification standards, which 
include five fundamental HSE criteria.  
This process is meant to help us select 
those vendors that both adhere to and 
support our basic HSE culture.

Stage 2 – Scope of Work preparation 
by contract holders 
Our procurement group has developed a 
standard checklist which is used by contract 
holders in compiling specifications for 
scope of work/services. This checklist 
includes HSE issues identified by contract 
holders as mandatory and which must be 
complied with by the selected contractor. 
The depth of these questions depends  
on the complexity and risk profile of  
the services to be provided with more 
comprehensive questioning of potential 
contractors that would be engaged in 
safety critical operations or where the HSE 
risk is considered high. HSE risk ratings 
(ranging from high to low) are assigned to 
all services to be tendered. The contracts 
and procurement department ensures all 
these requirements are properly addressed 
in the Invitation to Tender (ITT) Package.

Stage 3 – Tender
Our standard ITT Package includes: 

•  Tender Evaluation Questionnaire, with 
appropriate HSE related questions 
depending on the HSE risk rating.

•  Standard Model Contract with HSE 

Schedule. Tenderers must confirm in 
writing their acceptance of the terms of 
this Schedule when submitting their 
Tender Proposal, otherwise they are 
automatically disqualified.

Stage 4 – Contract execution 
The selected contractor signs the contract 
which incorporates an Appendix with HSE 
Requirements as an integral part.

Post-Award
Stage 5 – Contract Performance 
The contract holder, with support of HSE 
representatives, is responsible for the 
management of HSE performance of  
the Contractor.

All new contractors start their engagement 
with Nostrum with kick-off meetings 
organised by the contract supervisor and 
supported by HSE representatives, at which 
Nostrum’s expectations are explained in 
detail. Further topics of discussions are 
clear identification of KPIs related to HSE, 
introduction of HSE responsible staff  
from both sides, and induction into the 
Company’s procedures and regulations.

Road Safety
In 2023, Nostrum continued to implement 
the following activities carried out over  
the years:

•  Planned /unplanned inspections of the 
technical conditions of the vehicles at 
Nostrum facilities by our employees  
and Contractor representatives.

•  Road safety inductions, training and 

safety stand-downs are being held on  
a permanent basis with Contractor 
personnel.

•  Ad-hoc inspections on road safety 
compliance (speeding, safety belt  
use, etc.) are held regularly.

•  Nostrum ensures compliance with Road 
safety procedure, Journey management 
plan and procedure for organising and 
carrying out transportation of oversized 
cargo in order to ensure road safety 
compliance to the Company rules.

•  The Routes for the transportation  

of oversized cargo are coordinated 
(accompanied if necessary) to ensure 
road safety along the route of movement 
of oversized cargo on the territory of 
Nostrum facilities.

•  The passage of a medical pre-trip 

inspection by drivers of the Company and 
contractors is systematically controlled.

•  Checks are being made of the safe 

condition for traffic of the carriageways of 
public roads, bridges, railway crossings 
and road structures on the territory of the 
facilities and along the route to Nostrum 
production facilities and back.

Hazard Observation  
Cards 
As part of promoting a safety culture 
among our employees and contractors, 
Nostrum continues to implement a hazard 
observation card process. This initiative was 
launched in 2019, when all employees and 
contractors were encouraged to report  
any unsafe conditions observed in the 
workplace. This helps to ensure that our 
employees and contractors are always 
mindful of safe working conditions and 
continuously help to improve the safety  
of our operations. 

GRI 403-5  

In-house HSE training 
and examination process
Nostrum provides in-house HSE training 
and examination designed to improve the 
HSE competencies of both Nostrum and 
contract personnel performing safety-
critical activities. To facilitate this, Nostrum 
acquired an industrial safety accreditation 
which allows the Group to conduct 
in-house HSE training and examination in 
areas such as industrial and labour safety. 
Group employees are continuously trained 
in labour safety, industrial safety and H2S 
rules. During 2023, 802 employees took 
advanced HSE training.

In 2023, HSE Workshops were carried out 
for field personnel to promote awareness 
on the following topics:

•  Work at Height

•  First Aid in case of heart attack

•  Permit to work

•  Emergency Response

•  Fire Safety

•  Personal Protective Equipment

Additional 2023 initiatives include:

•  A pop-up window appeared on the 

screens when logging in every day with  
a safety reminder from the QHSE 
department.

•  HSE Posters printed and displayed  

in prominent locations.

•  Monthly QHSE Reports are issued to 

communicate HSE performance.

GRI 403-3, 
403-7

Process safety 
In 2023, no Tier 1 or Tier 2 
process safety incidents were recorded at 
Nostrum’s production sites. According to 
the American Petroleum Institute’s 
definition, a Tier 1 and Tier 2 safety incident 
is an unplanned or uncontrolled release of 
any substances, including non-toxic and 
non-flammable materials, from a process 
that results in one or more of the following 
consequences:

•  An employee, contractor or 

subcontractor incurs days away from 
work, injury and/or fatality.

•  A hospital admission and/or fatality  

of a third party.

•  An officially declared community 

evacuation or community shelter put 
 in place, including precautionary 
community evacuation or community 
shelter in place.

•  Fire or explosion damage of at least 

US$100,000.

The selection of appropriate maintenance 
strategies and the classification of 
equipment as safety critical or non- critical, 
is based on the impact that such equipment 
failure has on safety. Nostrum employs  
a specific safety critical equipment 
maintenance program whereby resources 
are allocated in order of priority with  
critical systems taking precedence.

Vessel and Flow-line inspection 
programme
All vessels and main flow lines were 
inspected according to international and 
RoK standards at the frequencies described 
(2, 5 or 10 years). No defects were identified 
during the internal and external inspections. 
From 2023 onwards, all vessels and flow 
lines will require yearly inspection but this 
can be done externally without necessary 
shutdowns as was the case for internal 
inspections. The inspection will be focused 
on wall thickness and, as such, provides the 
same information as before.

Emergency response, Civil 
Protection Planning and Prevention
In 2023, no industrial accidents or oil spills 
were recorded at Nostrum’s operations. 
The Company has established and 
successfully exercises an emergency 
response system and undertakes measures 
to prevent oil and oil product spills.

GRI 2-25  
Emergency response 
and accidents preparatory activities
The Company has emergency response 
plans to improve our capacity to swiftly 
address unexpected occurrences, thus 
preserving operational continuity and 
mitigating adverse effects on individuals, 
the environment, our physical infrastructure, 
and our reputation. These plans are 
effectively communicated to our workforce, 
and those involved in emergency response 
undergo training to ensure proficiency in 
fulfilling their emergency responsibilities. 
We remain committed to upholding asset 
integrity and managing operations to 
effectively mitigate all significant risks 
throughout every phase of our activities.

Specifically, in 2023 emergency training  
of personnel has been conducted on  
a quarterly basis in order to prevent 
accidents and emergencies as well as to 
train personnel in emergency response 
 in case of their occurrence according to 
Emergency Response Plans emergency 
scenarios at all hazardous production 
facilities. In 2023, we maintained 
emergency response training and exercises 
involving credible emergency ERP 
scenarios at all hazardous production 
facilities.

Hazardous production facilities at  
Nostrum include:

•  Oil Terminal and Transfer Point in Beles

•  CF-Rostoshi Oil Trunk Pipeline

•  CF-ICA Gas Trunk Pipeline (GTP 

Orenburg-Novopskov)

•  OTU and gaslift system

•  CGTU-1,2 and LPG -1,2

•  Well Operations and gathering system

Health and safety continued

During training drills at every facility, the 
emergency operations center organised 
and coordinated possible emergency 
prevention and responses to accidents,  
as well as to ensure fire safety. During 
quarterly drills held at the facilities – EOS, 
the whole range of issues related to 
accidents and emergency prevention and 
elimination procedures was considered.

Overall control of all emergency drills was 
overseen by the Field Director, who is 
responsible for the implementation of 
industrial and fire safety measures.

We believe that these actions help maintain 
the proper level of skills and competencies 
among employees and executives and 
ensure compliance with legal process 
safety requirements and corporate 
standards.

Oil spill prevention 
GRI 2-25, 
The Group strives to have zero 
206-3
operational spills. Nostrum continues to 
undertake initiatives to prevent and reduce 
spills that include drills and training  
teams, timely maintenance, repair and 
replacement of equipment, monitoring  
of problem oilpipeline areas, etc.

Oil Spill Response Plan
We continue to enhance our spill response 
capabilities in accordance with the Oil  
Spill Response Plan (“OSRP”) within the 
Company’s production facilities.

This plan sets our response strategies and 
techniques, available equipment, and 
trained personnel and contracts and 
includes the following measures:

•  signal receiving action and notification 

scheme for rescue services;

•  notification procedure for the Company's 

contractors, state bodies and local 
authorities;

development, and also makes a forecast  
of possible consequences for production 
facilities associated with accidental oil spills.

•  responsibility allocation for rescue units 
organisation and management, and;

•  measures to be taken to ensure people’s 

safety and other actions.

Following directives from Oblast Akim in 
2023, we conducted an extensive Oil Spill 
Emergency Response drill in May at the 
Terminal and oil pipeline with the 
participation of the Company Emergency 
Response Team, and emergency response 
teams from Baiterek district, West 
Kazakstan Oblast. Ansar-S-group LLP, our 
contractor supplied the main equipment to 
the training site, conducted three drills for 
collecting of the spilled oil from the ground 
and water surface and one drill focused on 
extinguishing oil fires. The Asnar S Group 
staff received training on using the oil 
collecting equipment effectively. The 
standout results were recognised and  
the Company Managers received 
Certificates of Appreciation from the  
Head of WKO Department of Emergency 
Situations.

In addition, an annual monitoring of 
hazardous sections of pipelines, preparation 
for autumn-winter season and spring floods 
is made, especially in areas located in a 
possible flooding area. Monitoring of their 
condition is organised by contractors – 
Nysan Korgau andAnsar-S Group.

The OSRP has been annually reviewed  
and updated to consider the regulatory 
requirements, availability of resources to  
be involved. The OSRP gives substantiation 
of a possible emergency level, analyses 
scenarios of their occurrence and 

Introduction of emergency response plans 
and OSRP for Nostrum’s production and 
engineering personnel is documented  
in the briefing log at the workplace. In 
accordance with Industrial Control Charter 
the Facilities Manager and Field Director 
are responsible for the due and correct 
preparation of ERPs, and ensure compliance 
with safety requirements is controlled  
on a regular basis. If non-compliance is 
identified, corrective and preventive action 
plans are developed and implemented.

Boosting readiness of emergency 
rescue teams
To respond to emergencies, Nostrum 
established civil defence teams, whereby 
120 employees on a voluntary basis  
(60 people in each shift), are engaged  
to ensure the safety of the production 
facilities. In 2023, regular drills with civil 
defence staff were conducted as per drill 
plans. The staff included to Civil Defence 
Teams was trained in 2023 at the facility of 
Ak-beren blow out elimination service in 
Burlin District WKO.

To maintain and conduct emergency 
rescue operations, the Company has 
long-term contracts with professional ERT 
– Ak-Beren LLP (gas rescue service) and 
Ansar-S-Group LLP (firefighters-rescuers). 
Ak-Beren, a professional blowout 
elimination service, is responsible for 
accident prevention at oil and gas  
wells, which is fully compliant with the 
requirements for oil, petroleum product, 
and other hydrocarbon spill response. 

Contained and non-contained oil spills

Materials and equipment available to the 
emergency response and rescue teams  
are certified and compliant with all 
requirements.

A high degree of readiness for the ERT is 
supported by regular drills and training, as 
well as theoretical knowledge. Drills and 
training are held on a quarterly basis at all 
facilities. Special attention during the 
ongoing emergency drills was given to 
those facilities where gas and oil contain 
hydrogen sulfide. All Emergency Response 
Plans were reviewed, updated and 
approved with Ak-Beren emergency 
response service and Ansar-S Group. 
Commanders of voluntary rescue and fire 
teams were additionally trained under the 
training program for unit commanders to 
maintain levels of skills and competence, 
particularly in relation to safety-critical roles.

The non-government fire service of 
Ansar-S-Group LLP, which has had a service 
agreement with Nostrum since 2022,  
was also involved several times (under  
our contract) in providing emergency 
responses in Baiterek during the elimination 
of the consequences of spring floods and 
summer steppe fires at the request of local 
executive bodies. Thus, Nostrum provides 
assistance to the administration and 
residents of Baiterek on an ongoing basis.

Organisation of communication 
with contractors on emergency 
response and prevention of 
possible emergencies 
A significant part of preventive and 
emergency organisation is performed by 
contractors for Nostrum. In order to ensure 
a high level of preparedness for emergency 
response, all drills and training were made 
with the participation of the following 
organisations:

•  Ansar-S-Group LLP – fire prevention.

•  Ak-Beren LLP – blowout prevention,  

gas rescue.

•  Nysan-Korgau – the organisation of 
access control and protection of an 
accident zone from unauthorised 
individuals.

HSE personnel assigned to each hazardous 
facility perform permanent control over 
work plans implementation by contractors 
as well as requirements of industrial safety 
standards. To achieve this, the Company 
uses checklists containing the entire range 

of issues under consideration – starting 
from document maintenance to work 
quality and safety. The HSE Department 
organises regular control field inspections 
at production facilities.

The control teams include representatives 
responsible for occupational health, safety 
and emergency response.

•  The most pressing issues are discussed 
with all contractors and facilities. Joint 
work on quality improvement of safety 
methods is organised on a permanent 
basis.

•  Representatives of contracting 

organisations participating in all 
emergency drills regularly held by 
Nostrum, have an opportunity to master 
up-to-date methods of emergency rescue 
operations and develop common rules for 
solving emerging problems taking into 
account available information on best 
practices in the oil and gas industry.

Alert system for employees and 
communities located near the 
Chinarevskoye Field
The Company is constantly improving 
internal procedures aimed at alerting and 
preventing emergency response cases, and 
in 2023 the Company maintained alert 
systems at Nostrum production facilities. 
The duty dispatch service promptly 
transmits information about the occurrence 
of accidents and emergencies to EOS-1 and 
EOS-2 to notify the management of the 
Company and government agencies.

In the event of an emergency, at the first 
level of emergency response, regular 
employees and contractor personnel 
located at Nostrum production facilities, as 
well as emergency response teams involved 
in the accident response are notified. High 
priority rescue and evacuation activities are 
performed to protect them. Territorial 
executive authorities (akimats) are notified 
of an accident in accordance with the 
notification scheme in case of a threat  
of the spread of adverse factors.

In the event of major accidents, operational 
teams of the second level are organised at 
the Company’s office in Uralsk. If necessary, 
the evacuation of personnel and 
communities is organised.

Firefighting activities arrangement
The Company systematically arranges 
operational control over compliance with 
industrial safety requirements, internal 
audits of the management system, 
conducts analyses of and processes the 
results of incidents and inspections, 
develops and monitors the implementation 
of corrective and preventive actions.

All Nostrum facilities at Chinarevskoye  
Field and Terminal are fire and explosion 
hazardous. Therefore, fire safety rules were 
developed for all facilities and controls over 
compliance with the rules are in place.

These activities include:

•  obligatory preventive inductions, fire 

safety training, control by line supervisors 
and responsible persons over the 
performance of work,

•  inspection of Ansar-S-group by a 

governmental authorised body and fire 
inspectors,

•  project expertise as to compliance with 

fire safety requirements during the 
reconstruction and technical upgrade of 
production facilities,

•  timely maintenance and function control 
of systems and fire protection means of 
facilities (by contractor – Batys Energon 
LLP), and;

•  continuous control of serviceability of 
fire- and explosion-hazardous process 
equipment and compliance with process 
flow charts.

Civil defence and emergency 
prevention measures
In 2023, in line with RoK legislative 
requirements, Civil Defence Plan annexes 
were revised. Training in civil defence for 
personnel training was organised at the 
Company’s offices. A special tactical 
exercise was conducted with the office staff 
on emergency evacuation in case of fire 
and the provision of medical assistance. In 
2023, 100% of office staff were provided 
with civil gas masks GP-7 with “Breeze”  
filter boxes.

In 2023, the West Kazakhstan Emergency 
Situations Department held annual 
inspection of the Chinarevskoye field and 
the office on fire safety. As a follow-up to 
the state field inspection on fire safety 
compliance the Company has developed 
an action plan and regularly provide 
information to authorities on its execution.

Strength through 
diversity
At the end of 2023, Nostrum's workforce 
stood at 571 employees, with 78% being 
male and 22% female (2022: 78% male and 
22% female employees). The Company 
remains steadfast in its commitment to 
establish key performance indicators (KPIs) 
for its HR department, specifically focusing 
on advancing diversity across all levels of 
the organisation. Particularly in the domain 
of diversity metrics, we aim to distinguish 
ourselves by increasing female 
representation across various tiers.

Nostrum has consistently upheld a 
corporate Equality and Diversity Policy for 
several years, underscoring our unwavering 
dedication to these principles. At the end 
of 2023, 21% of Group employees based  
in Kazakhstan were female, a figure that 
remains consistent with 2022. Furthermore, 
in the UK, 67% of employees were female 
(2022: 50%).

We take pride in our unwavering 
commitment to cultivating a workplace  
that celebrates diversity and fosters 
inclusiveness. Our core belief is anchored 
in recognising and appreciating the unique 
contributions of every team member, 
irrespective of their background or identity.

Acknowledging the continuous need for 
progress, the Board continues to prioritise 
diversity in upcoming appointments, with  
a specific focus on ensuring robust 
representation of Kazakh nationals in senior 
roles. Presently, 29% of department heads 
are female (2022: 32%). As at 2023 
year-end, our Senior Management Team 
comprises 27% females, marking an 
increase from the 20% recorded in 2022. 
We are targeting to further increase female 
representation at the senior management 
and at the department head level as 
possible. We actively advocate for  
female promotions in cases of parity in 
competencies and capacities. However, 
swift progress is impeded by the shortage 
of qualified female candidates willing to 
work in field-based roles, where a majority 
of our positions are situated, involving 
rotational shifts. And whilst we are 
encouraged by our diversity at Board level, 
we do recognise that diversity remains an 
ongoing issue in the oil and gas industry, 
particularly with regard to gender diversity.

Our Human Resources department actively 
promoted internal growth and worked to 
develop a diverse workforce at all levels of 
our organisation. In 2023, 25% of Group 
recruitment was female, a substantial 
increase from the 7.27% recorded in 2022. 
In 2023, five employees took parental  
leave and eight employees returned 
 from parental leave, all females.

The Company prioritises diversity in terms 
of nationalities, maintaining a diverse 
management team with representation 
from six different nationalities. Among 
the eleven members of the Senior 
Management Team, five are Kazakh 
nationals as at 31 December 2023. 
Additionally, there were no reported 
incidents of discrimination raised by  
any Group employees in 2023.

We believe diversity and inclusion are 
essential components to our business 
strategy. The company acknowledges that 
a diverse and inclusive workplace fosters 
better decision-making, stimulates 
innovation, and ultimately enhances 
business performance. We are committed 
to fostering an environment where every 
employee can thrive and achieve their full 
potential. We recognise that diversity goes 
beyond nationalities and encompasses a 
wide range of backgrounds, experiences, 
perspectives, and identities.

Promoting diversity and 
inclusion stands out as a crucial 
challenge and opportunity in the 
contemporary world. Businesses 
hold a significant responsibility 
in this regard, acting as 
influential proponents of positive 
principles and serving as 
commendable role models. 
Enhancing inclusion and 
diversity within our Group goes 
beyond mere correctness; we 
firmly believe it fortifies the 
qualities that contribute to the 
overall strength and 
improvement of companies 
through the creation of 
synergies.

Fundamentally, this effort revolves around 
recognising, respecting, and appreciating 
our unique differences. It transcends mere 
tolerance, delving into a profound 
understanding of each individual and an 
exploration of the factors that set us apart. 
Inclusive societies cultivate a profound 
sense of meaningful belonging, fostering 
support and value for individuals—integral 
elements crucial for the success of our 
organisational structure at Nostrum. We 
take pride in cultivating a diverse and 
inclusive workforce, providing a home for 
individuals from various backgrounds.

Undoubtedly, our people constitute the 
cornerstone of our success. Actively 
engaging with individuals possessing 
diverse assessments and perceptions leads 
to superior decision-making, increased 
innovation, and a more profound 
commitment in the workplace.

Diversity Action plan 
This year once again, we have endeavoured 
to enhance and progress in our promotion 
of diversity and inclusion within our 
organisation. Several initiatives have  
been improved, and others have been 
implemented.

Among them, a program aimed at 
addressing the under representation  
of certain disadvantaged groups, the 
“Targeted Recruitment Program” has been 
created. This initiative focuses on attracting 
and hiring individuals from diverse 
backgrounds, such as women, minorities, 
and individuals with disabilities. 

To reach that goal, concrete measures have 
been put in place, like discussing with 
external organisations and networks for 
collaboration to broaden our talent pool 
and ensure equal opportunities for all, as 
well as training our HR team to conduct 
inclusive recruitment interview and write  
an inclusive job advert.

We have developed the Company’s 
Inclusive Buddy Program, designed to 
establish a framework that facilitates the 
integration of new hires through mentoring 
experiences. Our aim is to foster a 
welcoming, friendly, and respectful  
work environment for all members.

We have established comprehensive D&I 
training programs aimed at raising 
awareness and providing knowledge  
on various topics, including equity and 
equality, stereotypes and biases, 
discrimination and prejudice, sexism and 
disability in the workplace, culture, and 
microaggressions. By embracing this 
approach, the organisation seeks to  
create a workplace where every employee 
feels valued and respected, fostering a 
collaborative and innovative atmosphere. 
This, in turn, will enhance employee 
engagement and satisfaction, ultimately 
contributing to long-term growth  
and success.

We have proposed the institution of a 
zero-tolerance approach to discrimination, 
harassment, and bullying, indicating that 
any documented incidents of harassment, 
discrimination, bullying, or victimisation will 
be treated seriously and could potentially 
lead to disciplinary action, including 
dismissal, with or without notice. This  
policy is currently under review and 
pending final validation.

Through our endeavours, we have 
observed a significant rise in the interest 
regarding diversity within our workforce, 
evidenced by an increased number of 
employees actively participating in our 
surveys and e-learnings and engaging in 
discussions with the Human Resources 
Department.

Moving ahead, we are dedicated to 
boosting diversity and inclusion in our 
organisation. For 2024, we plan to hold 
monthly onsite training sessions led by a 
dedicated coach three times a month as 
part of our D&I program. Our focus will be 

on creating mentoring programs linked to 
our Targeted Recruitment initiative to offer 
guidance, networking opportunities and 
professional growth to underrepresented 
groups.

We will closely monitor the Buddy Program 
and its implementation to ensure seamless 
integration of new hires, while also 
gathering feedback from employees  
and their assigned buddies. Additionally, 
we plan to create a user-friendly and 
comprehensive on-boarding manual to 
assist new team members during their  
first days.

Furthermore, we plan to establish employee 
affinity groups, diversity councils, and 
networking groups to support 
underrepresented members of our 
workforce. These initiatives will offer 
networking, mentoring, and career 
development opportunities, thus 
cultivating an inclusive environment that 
promotes a sense of belonging for all 
individuals within our organisation.

Regarding anti-discrimination measures, 
the Nostrum Code of Conduct safeguards 
all employees and contractors from 
unlawful discrimination based on aspects 
such as ethnicity, sexual orientation, 
disability, socio-economic background, 
age, gender, educational and professional 
backgrounds.

Education and training 
Investing in the development of our people 
is crucial for fostering economic self-
sufficiency within the local communities 
where we operate. Under the terms of the 
PSA, we are required to spend 1% of our 
annual Chinarevskoye field development 
costs towards education and training.

In 2023, 500 employees benefited from 
education and training programmes  
(2022: 507 employees). Our total Group 
training costs in 2023 were US$0.6m  
(2022: US$0.4m) and the total number  
of training days in 2023 was 5,702 days 
(2022: 6,961 days).

In 2023, Nostrum supported numerous 
educational programs, including MBA in 
Global Banking & Finance, ESG reporting: 
GRI Standards-Oil and Gas course, 
Document control foundation course,  
Oil Field Management Production 
Performance and Forecasting Analysis 
course, Mayekawa equipment. Module-unit

investigation (TapRoot Why Tree, 5 Why) 
course training was undertaken by 
operational and head office teams, 
department heads, specialist engineers 
and other technicians at different levels 
across the organisation.

HSE training (including fire safety) is carried 
out at least annually in accordance with our 
operating practices and as required by  
the PSA.

Employee relations and  
social guarantees
Nostrum prides itself on being an integral 
community partner and one of the largest 
employers in western Kazakhstan, with 98% 
of Group employees hired locally and 92% 
of all employees being RoK nationals. As at 
31 December 2023, Nostrum had a total of 
571 employees from 12 countries.

We offer all staff members competitive 
benefits and remuneration packages in 
compliance with all regulatory, guidelines 
and requirements, which (to the extent 
applicable) are also applied to those hired 
as temporary or part-time employees.

In an effort to promote gender equality, 
we continued to monitor gender pay 
discrepancies. Emphasis has been placed 
on supporting female advancement, 
resulting in promoting seven females for 
their competences. In 2023, we continued 
to conduct our own gender pay 
discrepancy review with a grouping of 
employees based on their job function, 
seniority, location and other factors. As 
a result of this analysis, the following 
observations were drawn:

1.  Roles with higher pay are male- 

dominated (C-suite)

2.  We have seen that the gender pay gap 

has further narrowed in 2023 as 
compared to 2022, the average 
employee salary in Kazakhstan was 
2.6% higher for males (2022: 3.3 % 
higher for males) and the median 
employee salary in Kazakhstan was 
5.3% higher for females (2022: 1.4% 
higher for females). At certain levels 
female pay exceeds their male 
counterparts (Office), while in the Field 
the remuneration is higher for males 
than females.

Despite short-term variations, our 
commitment remains steadfast towards fair 
and balanced recruitment and promotion 
practices along with consistent skills 
evaluation. We aim to increase the 
presence of women in senior roles and 
areas of our businesses where they are 
currently under-represented, with the 
long-term goal of eliminating the gender 
pay gap. The Board will continue to monitor 
any gender pay discrepancy by defining 
targets and activities to address any 
inequalities discovered.

Hiring and staff 
turnover
As part of the Company’s costs optimisation 
plan, in 2023, 48 employees (of which  
36 males and 12 females) were released  
or agreed to voluntarily resign, and their 
positions were not filled (2022: 48 
employees). This was the main cause of 
staff turnover. The number and percentage 
of new employees hired in 2023 was 52 or 
9.1% (of which 13 were females and 39 
were males).

Workforce  
representation
In 2018, the Company put collective 
agreements in place to provide for 
workforce representation. In 2023,  
Chris Hopkinson was appointed as the 
Company's non-executive director 
designated with the task of obtaining the 
views of the Company's workforce and 
feeding these into the Board's decision-
making processes. In November 2023, 
Chris Hopkinson met with members of the 
workforce in Kazakhstan and obtained 
feedback regarding various matters of 
importance to the workforce.

The Board of Directors strives to adopt  
best practices in corporate governance, 
including engagement with the Group’s 
workforce. In particular, the Board wishes  
to understand the views of the Group’s 
workforce and to take such views into 
consideration in Board discussions and 
decision-making. Communication between 
the workforce and the Board is often 
referred to as the “employee voice”, and it is 
hoped that a wide selection of views from 
the workforce can be gathered through a 
range of formal and informal channels.

Such channels are intended to help the 
workforce share ideas and concerns with 
senior management and the Board. This 
communication provides useful feedback 
about business practices from those 
delivering them and can help empower 
colleagues. The Board encourages 
individuals to raise any concerns they may 
have. Doing so acts as an early warning 
system for actual or potential problems and 
helps to manage risk. The Board actively 
listens to workforce concerns and 
subsequently provides feedback on how 
the matter raised has been considered, 
including any action taken. The Board 
emphasised that the workforce should  
feel safe to raise concerns.

Human Rights Policy  
Throughout 2023, the Group had a Human 
Rights Policy which reflects the desire to 
comply with industry best practice and the 
HR department has raised its awareness on 
the numerous benefits and interests that 
our Human Rights Policy provide to our 
organisation.

First and foremost, a Human Rights  
Policy demonstrates our commitment to 
upholding fundamental principles of 
human dignity, respect, and equality. By 
establishing a framework that promotes fair 
treatment of employees, stakeholders, and 
communities, we can enhance our position 
as a responsible and ethical business that 
contributes positively to the social and 
economic development of the regions 
where we operate.

In addition to these ethical considerations, 
there are practical benefits. By promoting 
diversity, inclusion, and non-discrimination, 
we can attract and retain a more diverse 
and talented workforce. Furthermore, a 
Human Rights Policy can help to mitigate 
legal, financial, and reputational risks 
associated with human rights violations.

Moreover, a Human Rights Policy can  
also enhance our relationships with key 
stakeholders, including customers, 
investors, regulators, and civil society 
organisations. By engaging in transparent 
and constructive dialogue about human 
rights issues, we can build trust, and 
credibility.

The Human Rights Policy is in addition to 
the Nostrum Code of Conduct (Code), 
which defines the principles that guide 
business conduct and provides a non- 
exhaustive outline of what Nostrum 
considers permissible conduct by its 
employees. These principles include 
provisions relating to human rights and 
diversity in the workplace, insider dealing 
and insider information.

healthcare system, in projects aimed at 
supporting cultural, sports and educational 
programs and to involve new communities 
in the social development of the region 
(Establishment of the Public Council of 
Gorbunovo village). In 2023, the company's 
charitable expenditures in support  
of the local communities exceeded 
US$0.4m. The company's most significant 
investments in support of local 
communities in 2023 were as follows:

Contribution to regional development
•  construction of a park in Beles and the 

planting of fruit trees;

•  assisting neighbouring communities to 
prevent natural disasters during severe 
weather conditions (blizzards, snowfalls, 
floods) by providing special machinery 
and equipment.

Supporting schools
•  providing funds for repair and 

improvement of material and technical 
base for general education schools and 
preschool institutions, purchase of school 
supplies for children from large families 
and low-income families.

Promotion of sports
•  providing financial assistance to young 

athletes and winners of various 
intellectual academic competitions to 
participate in international competitions 
and contests.

•  acquisition of medical rehabilitation 
trainers for Daryinsk Social Services 
Center, charitable assistance to Disabled 
People Society;

•  allocation of funds for children requiring 

treatment outside of Kazakhstan;

the highest level of social 
responsibility. Our commitment 
extends to providing both social

Spend with local suppliers
We are committed to partnering with local 
companies and in 2023 we spent 74.89% (in 
2022: 54.25%) of our supplier budget on 
RoK national suppliers. The increase in 
percentage is primarily attributed to the 
relatively lower restructuring advisor fees 
incurred in 2023 as compared to 2022. In 
addition, activities such as GTU3 re-start 
and appraisal programme on the Stepnoy 
Leopard fields, further contributed to the 
heightened proportion of spending on RoK 
national suppliers.

Environmentally friendly: 
Liquidation fund contribution
Under the terms of the Chinarevskoye PSA, 
Nostrum is obliged to accumulate a cash 
reserve liquidation fund which by the end 
of the PSA should total US$12.0m

structuring our activities to 
minimise negative impacts  
on the environments in which  
we operate. We adhere to the 
environmental regulations  
of RoK, which are aligned with 
international standards, and we 
are actively pursuing initiatives  
to reduce emissions and waste. 
In 2023, there were no fines or 
sanctions against the Group  
for non-compliance with 
environmental regulations. 
Furthermore, we recognise the 
importance of climate change 
and are committed to mitigating 
our greenhouse gas emissions.

Climate change
Nostrum acknowledges the extent and 
significance of its operational impacts  
and aligns them with the significance of 
sustainable use of natural resources, 
environmental preservation and  
mitigation of climate-related risks.

As a producer, our operational activities 
contribute to greenhouse gas (GHG) 
emissions, and we recognise the 
responsibility to minimise our impact  
on the climate in a responsible manner. 
Reducing emissions is a corporate goal  
of top importance.

We understand that hydrocarbon 
exploration and production significantly 
contribute to GHG emissions, and 
therefore, we are committed to addressing 
climate change. In 2023, one of our primary 
corporate social responsibility goals was to 
minimise the impact of our operations on 
climate change, which continues to be a  
key focus for Nostrum.

Nostrum organises its operations to adhere 
to the emissions limits specified in the 
Environmental Emissions Permit issued by 
Kazakhstan and establishes internal targets 
that are significantly stricter than those 
approved by the authorities. 

When applying for an Environmental 
Emissions Permit, preliminary standards  
for maximum permitted emissions are 
determined, based on the previous  
2-3 years of historical data.

The Board is responsible for ensuring that 
Nostrum complies fully with Listing Rule 
14.3.27R and Listing Rule 9.8.6R(8) in this 
annual report. Moreover, the Board is also 
responsible for the governance, strategies, 
risk assessment, management systems and 
KPIs relating to climate change and GHG 
emissions.

GHG emissions  
reporting approach
Nostrum seeks to minimise all GHG 
emissions and remains committed to 
investing in new technologies to enhance 
its GHG emissions performance. Nostrum 
fully complies with GHG emission 
regulations in the UK and Kazakhstan and 
has been monitoring and reporting GHG 
emissions since 2011.

The objective is to improve surveillance, 
increase transparency, develop a data- 
driven culture that provides employees with 

the ability to identify and act on insights, 
targeting maximum energy efficiency with 
a minimum carbon footprint through 
proper monitoring, process digitalisation, 
further process optimisation.

The Company’s GHG reporting period is 
aligned with the period in respect of which 
the Directors’ Report is prepared.

The majority of our emissions stem from the 
combustion of fuel gas within gas turbine 
units, boilers, process heaters, and 
compressors. Additional emissions occur 
during flaring, when no other alternatives 
are available. Our emissions levels are 
steadily decreasing year by year, excluding 
one-off items, as shown in the chart on 
page 66.

According to the new 2022-2025 
Kazakhstan National GHG allocation Plan, 
206,650 tonnes of CO2e were allocated to 
Nostrum. Our actual CO2 emissions in 2023 
were 176,277 tonnes and our actual GHG 
emissions in CO2 equivalent were 180,157 
tonnes, which include three other gas types 
as provided in Table 5 on page 72.

It is important to note that an active energy 
policy with the implementation of many 
initiatives was conducted during 2023, 
however several crucial moments 
influenced the increase in emissions in  
the second half of the year. While flawless 
hot commissioning and re-start of third 
technological gas treatment line in terms of 
quality and safety took place, since August 
the increase in emissions was inevitable 
due to the larger amount of equipment in 
operation and significantly higher fuel 
consumption requirement. In addition, 
since the 19th of December, the Company 
received the first gas from Ural O&G for 
processing, this third party feedstock has 
also contributed to the higher fuel 
consumption.

More detailed information on GHG 
emissions in 2023 are presented on  
pages 70–72. 

As part of the RoK regulations on 
production and emission reporting as well 
as for improving the transparency of all 
related business processes and KPIs 
monitoring, in the first half of 2023, 
Nostrum has completed expansion of its 
“Automated Reporting System phase III” 
(“ARS”) by including approximately 1,000 
“tags” in the process calculations, allowing 
real time readout of data.

and prepare for phase IV.

The fourth phase is ongoing and predicts 
the build up and running of full scale live 
Chinarevskoye field modules, adding and 
integrating Ural O&G third party feed stock 
and GTU-3 plant data into the existing 
system. In parallel, work is underway to

Current and future GHG  
reduction initiatives
Nostrum continues to invest in current and 
future technological advancements in 
order to effectively detect, monitor and 
prevent GHG emissions. The Company has 
the following technology in place to 
proactively monitor, limit and reduce  
its GHG emissions:

•  397 methane detectors to monitor 

equipment maintenance and pressure 
valve replacement exercises;

•  Mobile methane detectors in  

gas flowlines;

•  Use of cross exchangers in all Gas 

Treatment Units to pre-heat cold streams 
entering a heated process system by use 
of heat from hot streams exiting the 
system and requiring cooling;

•  Waste heat recovery system at CGTU-3 
– exhaust gases from the compressor 
units are used for heating the buildings 
and preheating the utility fluids in the 
plant, resulting in reduced fuel gas 
consumption;

•  Vapour Recovery Systems (VRS) installed 
in oil and condensate tanks to inhibit 
hydrocarbon evaporation during storage 
and transfer;

•  Hydrocarbon Recovery System (HCRS) 
installed in LPG loading terminal to 
prevent hydrocarbon ‘bleeding’ into the 
atmosphere;

•  26 MW power station generates 
electricity for use in the field and 
therefore limits the use of diesel-powered 
heaters;

•  Installation of automated flowmeter-
measurement on flare-lines on Oil 
Treatment Unit successfully completed in 
Q4 2023.

In recent years, the Company has 
implemented a number of projects which 
have had a continuous GHG reduction 
effect, such as:

•  Well automation flaring prevention on 

three wells during processing – 1,983.61 
tCO2 e /year;

•  Electric driven LPS compressor instead of 

fuel gas driven – 1,697.76 tCO2 /year;

•  Waste Heat Recovery project at GTU-3 
with an annual GHG reduction of 2,072 
tonnes of CO2;

•  Flaring reduction to the minimum due  
to proper production optimisation 
management, real time production 
monitoring and by shutting down the 
wells during any intervention with annual 
GHG reduction 4,000+ tonnes of CO2.  
It should be noted that GTU-3 hot 
commissioning/re-start and acceptance 
of Ural O&G third party feedstock have 
been done seamlessly with almost 
absence of hydrocarbons flaring and 
additional carbon footprint thanks to 
good preparation and execution of 
subject processes;

•  Implementation of some smaller 

initiatives took place in 2023 as well: 
Replacement of existing light sources 
with more efficient ones, automatisation 
of hot water boilers in field buildings, 
improvement of thermal insulation of the 
field pipelines and boiler system piping.

The Company is also appraising and 
investing in the following technologies  
to assist in the proper identification, 
accounting, and mitigation/reduction  
of GHG emissions:

•  Full asset digitalisation – Integrated 
production accounting and GHG 
emission quantification tools that give a 
holistic view of the entire hydrocarbon 
value chain as well as forecasting 
capabilities. Support digital transformation 
initiative of our assets;

•  Perform digitalisation of all our assets and 
business processes, data collection and 
reporting systems by 2026;

•  Perform Digital transformation of our 

company, by 2035;

•  Several projects that aim reduction  

of the fuel gas consumption are being 
evaluated targeting substantial reduction 
of GHG Emissions and None GHG Air 
Emissions: Installation of a Waste Heat 
Recovery Boiler for amine regeneration 
heat and technology line requirements;

•  To reduce our dependence on fossil fuels 
by investing in renewable energy, the 
company is currently investigating the 
different options like application of 
thin-film PV (Powerfoil) as solar solution 
for storage tanks and roofs.

The technology for GHG detection and 
quantification is constantly evolving, 
however, the Company continues to 
explore key technologies that will assist 
with the objective of GHG emissions 
reduction.

In order to further reduce GHG emissions, 
employees working at production facilities 
are transported via buses instead of using 
personal vehicles.

Nostrum is also considering various 
additional GHG reduction initiatives for 
2024 and future years.

Climate disclosures
In 2023, we participated in the CDP 
(formerly Carbon Disclosure Project) for  
the fifth year in a row, a key medium for 
companies to disclose their environmental 
impact and risk management as well as 
continue to focus on GHG emission 
reduction strategies. An independent 
assessment of our Climate Change 
response led to Nostrum achieving a “B-” 
score for the second consecutive time since 
joining the project. The Water management 
section also received a “B-” rating, 
consistent with our 2022 score. These 
scores enabled us to meet our 2023 KPI 
target, elevating our status from the 
previous Awareness Band (“C/C-” score)  
to the Management Band (“B/B-”) in the 
Climate Change module. The result also 
demonstrates that the policies and 
procedures we have developed in recent 
years are positioning the Company to 
effectively address the issue of climate 
change in the present and future. 
Furthermore, our “B-” score places 
Nostrum ahead of the average “C” score  
of its’ peers in the oil and gas industry.

Decommissioning
According to the regulations on subsoil 
use, it is required that all production 
facilities owned by subsoil users and the 
associated land be brought to a condition 
that ensures the safety of life, public  
health, and environmental protection. 
Furthermore, the consequences of subsoil 
users' activities must be resolved as 
outlined in the legislation of the Republic  
of Kazakhstan. The closure of subsoil use 
objects follows the guidelines laid out in a 
Liquidation Project, which is prepared by a 
design organisation holding a valid license 
for environmental protection services. All 
necessary decommissioning actions are 
detailed in the Liquidation Project created 
by NIPI Neftegas.

Waste, water and  
soil management 
Nostrum's operational activities are subject 
to thorough environmental monitoring, 
which includes detailed management 
systems for waste, water, and soil. The 
company conducts testing of air, soil, and 
sub-surface water to ensure compliance 
with sanitary and epidemiological 
standards as stipulated in Kazakh 
legislation.

Nostrum consistently monitors its 
regulatory responsibilities and is equipped 
with systems to monitor and report on 
these obligations and commitments 
through regular environmental 
assessments of waste, water, and soil  
at the Chinarevskoye field.

Waste management  GRI 306-1, 306-3
Waste management 
includes the daily control of sites for 
temporary storage of production and 
consumption waste, accounting, 
transportation and transfer  
to a third-party contractor.

All generated waste is transferred under  
a contract to the following third-party 
specialised organisations:

•  West Dala LLP

•  Help Ecoil LLP

•  TuranPromResurs LLP

•  Oral Tazalyk KZ LLP 

In 2023, the volume of waste generated at 
the Company’s facilities totalled 2,747 
tonnes, consisting of 40 different types of 
industrial (used filters, cartridges, medical 
wastes, batteries, etc.) and domestic waste 
(plastic bottles, used paper), 46% of which 
was transferred for processing by the above 
mentioned companies.

Drilling waste was processed in the Field by Help Ecoil. Soil and water survey results 
demonstrated compliance with all applicable environmental legislation.

Water management 
In meeting our environmental responsibilities, we recognise the importance  
of water resources in areas with limited water supply, and we acknowledge  
the importance of having access to fresh water.

It is paramount for us to effectively manage water consumption and we strive to deploy the 
most efficient water management techniques to handle fresh water in a balanced and 
sustainable manner. We seek to fully understand and minimise our operational water 
footprint and manage our activities in a way that protects our shared water resources.

We aim to comprehensively minimise our operational water footprint while safeguarding 
our shared water resources. We are dedicated to establishing robust water management 
practices across all our assets and conduct thorough assessments, target setting, 
monitoring, and corrective actions.

Nostrum’s water injection requirements are 
up to 1,200 m3 per day (average injection 
approximately 700-800 m3 per day), of 
which 400-550 m3 per day are injected from 
formation water production. The deficit is 
compensated through production from 
water wells. None of these water wells 
competes with fresh water supply to nearby 
communities. Five out of seven injectors are 
currently in operation with one disposal 
well used as a backup. The current system 
has sufficient capacity and flexibility to 
handle forecast water injection volumes.

The Company has initiated a series of 
measures to improve formation water 
treatment and injection processes. These 
measures include focusing its resources on 
process improvement in the treatment of 
water used in upstream operations which 
will lead to combating corrosion, reducing 
oil contamination, reducing growth of 
sulfate, reducing bacteria and the 
formation of inorganic scale. A full review 
was initiated in 2021-2022 on process 
effectiveness and chemical efficiencies and 
mitigating actions taken ensure compliance 
with Kazakhstan’s environmental 
regulations and has the additional benefit 
of reducing water treatment costs.

Water Treatment & Injection System 
Upgrade Phase I project has been 
completed, achieving some modest 
improvement by modifying injection points 
of applied chemicals and adding a second 
water storage tank (less suspended solids 
in water). Field trials by different vendors 
did not provide expected results. Project 
phase II has been initiated in 2023 scoping 
low-cost modification/adjustment of the 
existing treatment system. Longer term 
options will follow after further review.

•  ESG friendly solution – less waste (oil 

sludge) generation and utilisation, less 
volatile HC evaporation.

Currently testing of results is ongoing 
accompanied with fine tuning of 
technology. Preliminary good results  
have been achieved.

Wastewater discharges 
GRI 303-4
Reasonable and careful conservation of the 
ecosystem with clean water and access to 
water resources is one of the main factors of 
sustainable development. The Company's 
main approach to solving the problem of 
rational water use is to use water recycling 
and reuse systems, increasing the degree 
of wastewater treatment and reducing 
water abstraction from natural sources.

To prevent the negative impact of 
wastewater on the environment, we process 
wastewater using special artificial reservoirs 
such as evaporation ponds, filtration fields 
and a landfill for formation water and 
industrial wastewater.

We have the following artificial ponds:

•  Evaporation ponds GTP-1,2,3 

“conditionally clean” storm wastewater;

•  Polygon for formation water and 
industrial wastewater disposal;

•  Filtration fields, domestic wastewater 
after treatment at the liquid mud plant.

used as background information:

•  confirmed better injected water quality 
by this option in 2018. It is expected 
further improvement, unlike in 2018, two

Energy and resource efficiency policy and methane emissions management policy
The Company strives to use energy in the most efficient, cost effective, and environmentally responsible manner possible. Nostrum 
committed to consider energy efficiency as a factor in production operations development, in process and facility design and in the 
procurement of goods and services, whether it is further development of existing assets, appraisal of new upstream assets or midstream 
tiebacks.

In 2023, the Company has demonstrated full compliance to active Energy Management. During 2023, the Company published the 
“Methane Statement” and developed an “Energy Efficiency report” with short, medium and long term ESG targets. Nostrum continues to 
review and expand on metrics for reporting environmental, social, and governance (ESG) performance. A set of short/long-term actions 
with accountable metrics and interim targets has been established in 2023 addressing all areas and entities of energy efficiency 
improvement. Additionally, the Company developed an “Energy Management Policy” which includes not just regulatory compliance 
requirements, but striving towards achieving lower carbon targets.

GHG emission results GRI 305-1, 305-2
Kazakhstan signed the Paris Agreement on August 2, 2016 and ratified it on November 4 of the same year. All Parties to the Paris Agreement 
have their own commitments to reduce greenhouse gas emissions. Kazakhstan has set itself an ambitious unconditional goal – by 2030 to 
reduce greenhouse gas emissions by 15% from the 1990 level. In February 2023, Kazakhstan adopted a strategy to achieve carbon neutrality 
by 2060, which outlines a series of essential measures aimed at reducing emissions and achieving de-carbonisation in the economy.

Starting from 2021, quotas are based entirely on the application of the benchmarking method. Greenhouse gas emission quotas in the 
National GHG allocation plan for 2021 were calculated by multiplying the benchmarks by the average value of production for 2017-2019.

In the National GHG allocation plan for 2022-2025 quotas to companies were also calculated entirely by applying the benchmarking 
method. Carbon credits in the National GHG allocation for 2022-2025 were calculated by multiplying the benchmarks by the average 
value of production for 2017-2019.

generated in operations” – 289 tons of CO2, “Capital goods” – 150 tons of CO2 and “Goods and Services” – 1,430 tons of CO2. (352 tons  
of CO2 for one category in 2022). In total Scope 3 emissions were in amount of 1,868 tons of CO2. This is the Company's second step in 
disclosing Scope 3 emissions. Detailed results of Scope 3 calculations will be covered in CDP submission for 2023.

A breakdown of GHG emissions by gas type is shown in Table 2. The GHG emissions predominantly consisted of carbon dioxide and 
methane. Scope 1 emissions are generated directly by equipment owned and operated by the Group. The equipment includes boilers, 
heaters, diesel stations, gas turbine units and compressors. Scope 1 emissions also include flaring and hydrofluorocarbons emitted by 
refrigeration units and climate control systems, such as air conditioners.

Indirect GHG emissions (Scope 2)
Nostrum does not use purchased steam, heating or cooling. Electrical power is the only purchased power related to indirect GHG 
emissions and it is supplied to Nostrum facilities via the Zelenovskaya distribution network (ZapKazREK JSC), through its subsidiary  
Batys Energoresursy LLC. The regional emission factor (0.27086 tCO2/MWh) was calculated using Methodological Guidelines for the 
Calculation of GHG Emissions from Electrical Power Stations and Boiler Houses (Astana, 2010) and the regional net thermal efficiency  
of Urals Natural Gas Fired Power Plants (73.3%).

Emissions intensity ratio GRI 305-4
Tonnes of CO2 per tonne of output is a recommended intensity ratio for the oil and gas sector, as per Appendix F of the UK Government’s 
Defra Environmental Reporting Guidelines (2013). Taking into account the variety of products of Nostrum – crude oil, stabilised condensate, 
LPG and dry gas – the chosen intensity ratio is expressed in metric tonnes of CO2e (mtCO2e) per tonne of oil equivalent (mmboe).

Table 6 shows intensity ratios for total (Scope 1 and Scope 2) emissions in the period 2016-2023.

In-process control in canteens
Quarterly inspections are carried out in 
Nostrum canteens, during which samples 
of prepared meals, salads, wash water, and 
water are collected for bacteriological and 
chemical analysis. Additionally, 
assessments of lighting, workplace 
microclimate, noise levels, and ventilation 
system operations are conducted. Any 
instances of non-compliance are addressed 
through corrective actions, such as 
replacing lighting equipment, repairing  
air conditioners, and installing a new 
bactericidal lamp in the water  
treatment system.

In-process control of labour 
conditions at production facilities
To identify any discrepancies in the 
workplace, assessments were conducted to 
measure air quality, lighting, microclimate, 
noise levels, vibrations, electromagnetic 
fields, and power stations. Specialised 
contractor companies with the required 
permits and accreditation certificates were 
responsible for conducting these necessary 
measurements and investigations at 
Nostrum facilities. The results of the 
in-process control are reported to the 
relevant regulatory authorities, and an 
industrial environmental control report is 
uploaded to an electronic environmental 
portal.

In-process control, monitoring  
and health protection
The primary focus of the Company is to 
adhere to all legal regulations in the 
Republic of Kazakhstan concerning 
environmental protection, labour 
conditions at production facilities, and 
health protection. In this respect, Nostrum 
conducts ongoing monitoring and control 
across various areas.

Industrial environmental 
monitoring (IEM) and control 
IEM has been performed under the 
Industrial Environmental Monitoring 
Program developed based on 
requirements of RoK Environmental Code 
and other environmental regulatory & 
procedural documents and instructions. 
The program provides for environmental 
emissions monitoring and environmental 
medium impact monitoring of Nostrum 
operations.

Climate-related Financial Disclosures 

GRI 2-14, 201-2

Climate-related  
Financial Disclosures

We continued our journey 
of improving our disclosures 
and reporting in order to 
adhere as much as possible 
to TCFD’s recommendations, 
taking into account 
Nostrum’s operations  
and strategies.

Governance

TCFD recommendation: 
Disclose the organisation’s 
governance around climate 
related risks and opportunities.

    Read more about our strategy  
on pages 18-19.

a)  Describe the board’s oversight 
of climate-related risks and 
opportunities.

Following are some examples where the 
Board and its committees considered 
climate-related issues in 2023 and 2024  
to date:

Board of Directors
The Board and its committees, where 
appropriate, have oversight of climate-
related matters, which include climate risks 
and opportunities. Material issues and 
principal risks, including climate change 
indicators, are reviewed by the Board and 
committees.

Monitoring and performing management
The Board recognises that there may be 
potential financial implications in the future 
from changes in legislation and regulations 
intended to address climate change risk. In 
relation to these matters the Board also:

•  Reviews material issues and principal 

risks, including climate change indicators;

•  Sets general policy related to climate 

risks and opportunities, identifies where 
further actions are required and 
delegates authorities accordingly;

•  Approves material issues and principal 

risks, including climate change indicators 
and progress against those KPIs monitored. 
See pages 18-19 on Company KPIs and 
pages 103 and 108, where CEO KPIs 
include GHG emissions related targets.

TCFD Statement
We are working towards making our 
climate-related financial disclosures fully 
compliant with the TCFD Recommendations 
and Recommended Disclosures and hence 
compliant with FCA Listing Rule 9.8.6R (8) 
and UK Climate-Related Financial 
Disclosures (CFD).

We have made below disclosures against 
each TCFD Recommendation and 
Recommended Disclosure – noting where 
the Company is in full or partial compliance 
or where further work is planned to be 
undertaken to report in the 2024 Annual 
Report & Accounts.

Risk Management
ESG matters are integrated in each 
applicable area covered by the Group’s 
systems of risk management and internal 
controls, and the Board recognises their 
significance and importance. Further 
details on the identified ESG risks and 
related responses are disclosed within 
“Principal risks and uncertainties” section 
on pages 34-38.

The Management is responsible for ensuring 
that systems of risk management and 
internal control are in place to effectively 
manage and monitor climate-related risks 
and other ESG matters. Periodic updates are 
provided to the Board on such risks and 
relevant mitigating actions.

Capital or operating expenditure
Capital and operating expenditures, which 
are relevant to mitigating climate-related 
risks and other ESG matters, are budgeted 
and given highest priority in execution. 

Audit Committee
Following areas of the Audit Committee 
responsibilities are relevant for the 
climate-related matters:

•  Oversight of management’s process for 

identifying ESG risks and internal controls 
processes to ensure the accuracy and 
completeness of ESG information;

•  Monitoring of the performance against 
agreed and defined KPIs in respect  
of the Group’s ESG financial reporting 
disclosures and seeking independent 
assurance on behalf of the Board,  
where appropriate;

•  Review of the Company’s disclosures in 

the annual report in relation to the TCFD 
Disclosures and climate-related  
emerging risks.

  Read more on pages 93-98

When making assessments and preparing 
disclosures we have considered whether 
particular issues and related information 
may influence the economic decisions of 
the stakeholders. Such approach is in line 
with guidance and recommendations 
provided by TCFD in relation to materiality 
of information. Furthermore, the process of 
assessment of risks and their potential 
financial impact involved use judgements 
and estimates, which we believe are 
consistent with the TCFD Recommendations 
and Recommended Disclosures.

Strategy Committee
Emerging risks are identified, assessed and 
monitored at the HSE and ESG Committees 
led by CEO, and further escalated by CEO 
to the Strategy Committee of the Board, 
where necessary. 

The Strategy Committee is responsible for 
advising the Board on short-term, medium-
term and long-term strategic decisions of 
the Company (horizons defined on page 
78), including following activities relevant 
for addressing climate-related risk and 
other ESG matters:

•  Supporting the Board and Senior 

Management in formulating the overall 
strategy for the Company, with particular 
emphasis on horizon scanning, priorities, 
activities and outcomes.

•  Considering reports on overall 

performance in respect of the achievement 
of the objectives and outcomes contained 
within the Corporate Strategy.

•  Reviewing determined KPIs to assess 

performance with respect to the Group’s 
strategy.

  Read more on pages page 87

Remuneration Committee
Annual KPIs relating to climate change and 
emissions targets are approved by 
reviewed by the Remuneration Committee 
and upon its recommendation approved by 
the Board. The progress against those KPIs 
monitored and reported to the 
Remuneration Committee and the Board.

b)  Describe management’s role in 
assessing and managing climate-
related risks and opportunities.

Since the completion of the bond 
restructuring in early 2023, the newly 
formed HSE and ESG committees deal with 
various matters including among others 
climate-change related issues and 
execution of ESG-related targets and 
projects. Both committees are sponsored 
and chaired by the Chief Executive Officer, 
with meetings held prior to each Board 
meeting.

The Chief Executive Officer reports at the 
Board meetings on HSE and ESG matters 
including performance against climate- 
change related KPIs. The Chief Operating 
Officer is responsible for day-to-day 
operations, including the identification  
and evaluation of climate-related risks  
and opportunities. The Group Head of 
QHSE is responsible for the day-to-day 

management of HSE matters including 
climate-change related risks. Both the Chief 
Operating Officer and Group Head of 
QHSE report directly to the Chief  
Executive Officer.

The Chief Executive Officer, Chief 
Operating Officer and Group Head  
of QHSE together with appropriate 
operational staff meet at least four times  
a year at HSE Committee meetings. The 
committee monitors all HSE matters 
including those relating to climate-change, 
monitoring and reducing emissions, 
progress against KPIs, water and waste 
management, compliance with RoK 
statutory emissions, the climate-related 
impact of any significant capex or operating 
expenditure and identifying and agreeing 
on the course of action on climate-related 
initiatives, including energy reduction/ 
transition, emission management and 
prevention of unnecessary flaring. 

The HSE Committee also assesses 
preparedness and ensures focus in respect 
of statutory reporting requirements and 
changing legislative environments  
and investor requirements in the UK, 
Kazakhstan and internationally. Climate- 
related matters discussed at the HSE 
Committee drive climate related KPIs 
proposed by management to the Board 
(see pages 103 and 108 for more details). 

The Company also considered the 
climate-related matters in the process of 
due diligence prior to acquisition of the 
Stepnoy Leopard field, and given the 
limited prior activities on these fields,  
there was not sufficient basis to make 
assesements material climate impact. After 
the acquisition, the entity and the fields are 
integrated into the Group systems of 
controls and procedures on all matters, 
including climate-related disclosures.

Strategy

TCFD recommendation: 
Disclose the actual and  
potential impacts of climate-
related risks and opportunities 
on the organisation’s businesses, 
strategy, and financial planning 
where such information is material.

    Read more about our strategy  
on pages 18-19.

a)   Describe the climate-related 
risks and opportunities the 
organisation has identified over 
the short, medium, and long term.

The Company’s principal risks and 
uncertainties as described through the risk 
management process as described on 
pages 32-38. In the context of those  
key risks, the following climate-related 
transition and physical risks as well as 
opportunities were identified as relevant  
to Nostrum. Given that there were no 
significant changes in the Company’s 
principal risks and uncertainties, the 
climate-related risks have also remained 
largely unchanged compared to previous 
reporting period.

Policy and legal risks which Nostrum is 
facing are similar to other players in the oil 
& gas industry: 

•  Changes in state regulations may lead to 
increased costs for the business through 
carbon taxes, punitive flaring fines or 
outright bans, as well as potential 
additional costs for litigations relating  
to climate change.

•   New and evolving RoK reporting 
obligations may lead to higher 
compliance costs.

•  Risks of early asset retirement due to 

certain policy changes, such as emissions 
targets making it impossible to continue 
operations, or carbon pricing making 
operations commercially unviable.

We believe these risks are relatively low in 
the short-term but become more material 
over longer horizon as the global 
movement towards net zero strengthens.

In addition, according to our materiality 
assessments under ESG umbrella, the GHG 
emissions and gas flaring were identified as 
significant climate-related topics. These 
areas may pose potential risks to Nostrum’s 
business and stakeholders due to penalties 
for permit violations and non-compliance 
with environmental legislation.

Technology risks are considered relevant in 
the medium and long-term. As global and 
jurisdictional legislation evolves, we may 
need to allocate capital into emissions 
reduction investments such as carbon 
capture and storage, which may be 
non-value accretive, i.e. do not provide 
direct revenue, and therefore may impact 
the medium-long term value of the 
Company.

Market risks for the Company are mostly 
reflected in reduction in global demand for 
hydrocarbon products and volatility of 
product prices, which may directly impact 
our revenues, across all time horizons. In 
addition, increase in cost of raw materials 
due to climate-related supply disruptions 
may not only increase the cost base, but 
also cause delays and disrupt operations, 
which would lead to lost production and 
revenues. On the opposite, demand and 
product prices may remain at relatively 
higher than expected levels in the short 
and medium term, which may create 
opportunities for the Company to generate 
higher returns.

Reputational risks include risks of 
stakeholder concerns and disengagement 
as a result of the other climate-related risks, 
and also increasing difficulty in accessing 
capital markets for future growth 
opportunities. We believe these risks  
are less of a concern in the short-term since 
the Company has longstanding relations 
with its key shareholders and noteholders. 
However, these may become bigger  
risk in medium and long term.

Physical risks which may affect the 
Company and its operations include acute 
risks such as floods from local rivers and 
chronic risks such as severe rain and/or 
snow conditions. 

As climate change continues on the path it 
is today, we believe these severe weather 
events may occur more regularly and 
during unexpected periods of time  
and may further impact the business 
operationally and financially. Today, we 
operate successfully in the middle of winter 
where temperatures on the ground can 
drop to -30C. Although, Kazakhstan  
has a sharply continental climate and  
large diurnal and annual temperature 
fluctuations, such temperature changes are 
usually gradual. However, if temperatures 
were to change sharply within short period 
of time due to climate change, this could 
impact operations negatively, e.g. by 
reducing equipment productivity due to 
overheating, increasing fire risk, or on the 
opposite causing thermal expansion of 
pipelines and systems due sudden extreme 
temperatures. 

Seismic activity in Western Kazakhstan is 
relatively low, according to the Institute of 
Geophysical Research of the Republic of 
Kazakhstan and global seismic bulletins. 
Hence, risks of earthquakes affecting our 
business are considered low.

Further, flood events with overflowing 
riverbanks can severely impact our ability to 
transport LPG to the market and hence 
reduce our revenues.

Opportunities exist for the Company 
through resource efficiency and energy 
source. For the past several years the 
Company has been using own gas to 
generate electric power and using it for 
own operations. The Company is planning 
to continue this practice in the medium  
and longer-term to be as resourceful as 
possible. Financially, this saves us money by 
not purchasing electricity from the grid. As 
opportunities come up, the Company may 
look into investment in new technologies to 
become more energy efficient and reduce 
its GHG emissions.

From a resource efficiency perspective the 
Company looks into reduced water usage 
and consumption which can lead to 
reduced operating costs. Also making our 
offices more energy efficient has been 
identified as another initiative for the 
medium-to-long term, including 
improvements in the heating and  
lighting systems.

STRATEGIC REPORTClimate-related Financial Disclosure

Strategy continued

The Board and Senior Management 
continuously monitor planning and 
decision-making processes over 
short-term, medium-term and long-
term horizons, which also cover relevant 
climate-related risks and opportunities 
as described below.

Short term: three-year period to the end 
of 2026 over which the management 
and the Board monitor the Company’s 
liquidity and viability. The Company has 
a detailed financial plan which is actively 
managed and adapted according to 
changes in external circumstances. The 
climate-related risks are deemed to 
affect the Company in the short-term 
but are not as prevalent as they would 
be in the medium and long term.

Medium term: eight-year period to the 
end of 2031, which covers the full term 
of the PSA and used in relevant valuation 
models. Climate-related risks are 
factored into these models, and 
scenario analysis are performed using 
various hydrocarbon prices and off-take 
demand scenarios to support the Board 
in decision-making for field investment 
proposals in line with the Group’s 
strategy.

Long term: period covering beyond 
2031. This is defined by opportunities 
identified in line with the Group’s 
strategic initiatives, which are mostly 
affected by climate-related risks. These 
include risks associated with access to 
financial and capital markets as well as 
the ability obtain insurance, which may 
leave the Company exposed to extreme 
negative events. These other risks are 
further described below.

All transition risks are provided in equal 
weighting in our future business, strategy 
and financial planning. For physical risks, 
while important from a governance 
perspective, we apply a slightly lower 
weighting in our planning. Whilst present, 
we deem the financial and operational 
impact to be lower as we currently operate 
successfully in extreme weather today and 
believe we will do so going forward. 

We take a conservative approach in our 
forward planning and therefore do not 
factor in opportunities that may arise in  
the short, medium or long-term through 
climate change.

As described in the Governance section, 
we have a robust climate-change 
governance matrix in place to consider 
these risks widely. We have now devoted 
more resources into this governance matrix 
(including reporting) and these feature in 
our future strategic and financial planning. 
The matrix looks at the strength of the risks 
and opportunities identified in section  
a) above across the short, medium and 
long-term and assesses which of those  
risks has a direct financial impact.

In our CDP Climate Change submission for 
2023, we estimated the financial impact of 
several of the transition and physical risks 
outlined above. Our ambition is to upgrade 
the climate disclosure area and CDP rating 
for our Climate Change response and Water. 
Based on the results of the disclosure of data 
on the use and conservation of water 
resources the CDP climate rating has been 
improved to “B-” in 2022 from “C” in 2021, 
which is in line with the global industry 
indicator, and it was maintained at this level 
in 2023.

b) Describe the impact of climate- 
related risks and opportunities on 
the organisation’s businesses, 
strategy, and financial planning.

We acknowledge that the transition to a 
lower carbon economy presents both risks 
and opportunities for Nostrum. As 
described above, the impact on our 
short-term strategy and financial planning 
remains minimal, but we have in place the 
necessary flexibility to adapt as and when 
we see the risks evolve. In respect of 
medium term and long-term financial 
planning, we are cognisant of the climate-
related risks and our ability to execute 
various projects. Hurdle rates have 
increased on various investment proposals 
with carbon intensity, stressed hydrocarbon 
price scenarios and energy demand 
scenarios are factored into decision papers.

With respect to physical risks, we have 
factored this into our strategic planning 
through extended and more frequent 
maintenance periods. This reflects a period 
of downtime during which operations and 
revenues cease. 

We deem all transition risks (policy and 
legal, market, technological and reputation) 
to be material for the business in our 
strategic and financial planning. The 
transition risks, as outlined in (a) above, 
impact:

i.   reduced demand and lower pricing for 
our final products – resulting in lower 
future revenues, 

ii.   higher supply and material costs in our 

supply chain as suppliers shift away from 
servicing the oil and gas industry leaving 
a small number of viable options, 

iii.  high investment spend relating to 

climate risk mitigation activities through 
increased spend on climate-related 
research and development and 
operationally through increased 
downtime due to extreme weather 
events.

c)  Describe the resilience of the 
organisation’s strategy, taking 
into consideration different 
climate-related scenarios, 
including a 2°C or lower scenario

For the current year analysis and reporting 
on climate risk we studied various scenarios 
suggested by different international 
organisations and agencies and decided  
to refer Net Zero Emission by 2050 Scenario 
(“NZE Scenario”) developed by the 
International Energy Agency, and also  
took into account Kazakhstan’s Strategy on 
Achieving Carbon Neutrality by 2060.  
Nostrum considered the commitment of 
the government of the UK (where Nostrum 
is headquartered) to a net zero economy, 
but determined that such commitment was 
not relevant, because the overwhelming 
majority of Nostrum’s emissions do not 
count towards UK emissions.

The Net Zero Emissions by 2050 Scenario is 
normative, in that it is designed to achieve 
specific outcomes – net zero emissions from 
the energy sector by 2050 without offsets 
from other sectors, an emissions trajectory 
consistent with keeping the temperature 
rise in 2100 below 1.5 °C (with at least a 
50% probability) with limited overshoot, 
universal access to modern energy services 
by 2030 and major improvements in  
air quality – and shows a pathway to  
reach them.

As such, NZE Scenario outlines a course  
for attaining net zero emissions from the 
worldwide energy system by 2050, and 
assumes a transition based on three pivotal 
shifts across the global energy landscape: 
extensive electrification, unparalleled 
enhancements in energy intensity,  
and widespread international policy 
collaboration. In this scenario, the global 
economy shifts away from a predominantly 
fossil fuel-powered model to one primarily 
fuelled by renewable energy. Concurrently, 
the reduction in demand for oil and gas 
exerts downward pressure on prices.

As for Kazakhstan Strategy on Achieving 
Carbon Neutrality by 2060, it implies 
increase of the share of renewable energy 
sources in the country’s total energy 
balance to 15% by 2030 and reduction  
of GHG emissions by 15% by December 
2030, compared with 1990.

Taking these into account the company 
used the base-case scenario as described 
below, and a severe but plausible scenario 
for the purpose of testing its resilience 
across short-term and medium-term 
horizons:

1.  Base-case scenario (high carbon 

climate scenario – more than 4°C) – 
business development that implies a 
gradual attainment of carbon neutrality, 
taking into account a moderate pace  
of economic decarbonisation. This  
case is considered consistent with the 
base-case scenario used in the viability 
assessment (see pages 39-40).

2.  Severe but plausible development 
scenario whereby extreme changes 
happen in global economy and drastic 
measures are implemented towards 
Kazakhstan’s achievement of NZE (very 
low carbon climate scenario – less  
than 1.5°C).

The base-case scenario involves 
implementing energy efficiency measures 
to achieve the goal of reducing greenhouse 
gas emissions each year by 5% of actual 
emissions compared to the previous year. 
This scenario includes a list of measures for 
energy efficiency improvement, among 
which are the implementation of projects 
such as assets digitalisation and Automated 
Reporting System implementation, 
automated emission monitoring system at 
emission sources, installation of automated 
flowmeter measurement on flare-lines on 
the Oil Treatment Unit, Water Production & 
Injection System planning, Water Treatment 
& Injection System upgrade, replacement 
of existing light sources with more efficient 
ones and trees planting.

For the purpose of severe but plausible 
development scenario aimed at stress-
testing the company’s resilience we used 
two major assumptions:

1.  The first assumption centres around  

a downtrend in oil prices, which are 
projected under NZE Scenario to drop 
to US$42 per barrel by 2030 and further 
decrease thereafter, reaching US$25 
per barrel by 2050.

2.  The second assumption revolves 

around carbon prices, which were  
taken also from the NZE Scenario for 
emerging market and developing 
economies (without net zero emissions 
pledges), whereby carbon price are 
forecast at US$25 per tonne of CO2 by 
2030, US$85 per tonne of CO2 by 2040 
and US$180 per tonne of CO2 by 2050. 

We have examined various forecasts of 
carbon prices to stress-test our strategy. 
While analysing these forecasts, our focus 
has predominantly been on the NZE 
Scenario. Taking into account Kazakhstan’s 
strategy aimed at achieving carbon 
neutrality goals, the most relevant 
reference point under NZE Scenario would 
be carbon price forecasts for emerging 
market and developing economies with  
net zero emissions pledges, under which, 
carbon prices are projected to rise 
significantly by 2030, reaching an average 
of US$90 per tonne of CO2. However, 
according to the World Bank, the current 
carbon price in Kazakhstan is notably low, 
with projections indicating a carbon price 
of US$20 per tonne of CO2 by 2030 would 
be necessary to achieve just over half of the 
abatement target.

Given the multitude of predictions 
regarding carbon prices, ranging from very 
high to relatively low, we have decided to 
apply the middle point in our modelling 
and settled on the carbon price forecasts 
under the NZE Scenario for emerging 
markets and developing economies 
without net zero emissions pledges. 

These assumptions were applied to the 
three-year financial model to evaluate the 
resilience of Nostrum’s strategy amidst the 
challenges and opportunities posed by 
climate change in the short-term pursuant 
to the NZE Scenario and the Kazakhstan 
Strategy on Achieving Carbon Neutrality by 
2060. Building upon this evaluation, we also 
refer to the Viability Statement on pages 
39-40 of this report, where we consider the 
resilience of the company to various 
principal risks and uncertainties.

Stressing our short-term financial 
projections for these high-level 
conservative policy measure assumptions 
demonstrates that the Company in the 
short-term is resilient considering a 1.5°C 
climate-related scenario. Furthermore, it  
is our view that the Company has a solid 
financial base and sufficient flexibility in  
its business plan to be able to adjust 
adequately to extreme climate-related 
impacts. 

Our strategy is validated annually by the 
Board of Directors to ensure it remains 
relevant and resilient. Please refer to the 
Governance process for further details.  
The strategy will be adjusted if there are 
significant changes in the wider global 
environment.

Risk Management

TCFD recommendation: 
Disclose how the organisation 
identifies, assesses, and 
manages climate-related risks.

    Read more about our risk management 
on pages 32-33.

a)  Describe the organisation’s 
processes for identifying and 
assessing climate-related risks;

b)  Describe the organisation’s 
processes for managing climate- 
related risks;

c)  Describe how processes  
for identifying, assessing,  
and managing climate-related 
risks are integrated into the 
organisation’s overall risk 
management.

Nostrum has a robust governance structure 
through which climate-related risks are 
identified and managed. Specifically, the 
ESG and HSE Committees are the conduit 
through which climate-related risk 
management is enacted. The ESG and  
HSE Committees operate under the 
principle of 5 pillars:

i.  HSE leadership;

ii.  rigorous incident investigation;

iii. process safety and asset integrity;

iv. contractor HSE management; and

v.   environment and climate change 

including a commitment to reduce  
GHG emissions.

The fifth pillar is an integral part of our 
climate-related risk identification, 
assessment, and management process. 
Both classifications of climate-related risks 
(transition risks and physical risks) are 
considered as part of the process.

The ESG and HSE Committees oversee the 
design and implementation of systems of 
climate-related risk management and 
internal controls and manages and reports 
on risks. 

The Group Head of QHSE supports the 
Chief Executive Officer in his oversight and 
monitoring role and performs management 
and reporting on the risks.

The QHSE department is responsible for 
identifying climate-related risks which 
include potential effects on operations at 
asset level, performance at Group level  
and developments at regional level from 
transition to lower carbon economy or 
extreme weather events.

The processes described above are 
embedded into our overall Group Risk 
Management framework and form an 
integral part of Nostrum’s risk management 
and internal controls system. We include 
“climate change risks” as a principal risk and 
uncertainty on our Company risk register 
(see page 37) thus allowing the ESG and 
HSE Committees to manage any identified 
risks. This risk covers both physical and 
transitional climate-related risks and is 
reviewed annually by the Nostrum Board 
of Directors.

The Company endeavors to constantly 
improve its systems of risk management 
and internal controls. However, considering 
relatively short period of time since the 
implementation of the above-mentioned 
committees and relevant policies and 
procedures in early 2023, the Company 
does not report any further material 
updates on these matters in this report.

Metrics and Targets

TCFD recommendation: 
Disclose the metrics and targets 
used to assess and manage 
relevant climate-related risks  
and opportunities where such 
information is material. 

    Read more about our risk management 
on pages 32-33.

a)  Disclose the metrics used by 
the organisation to assess climate- 
related risks and opportunities in 
line with its strategy and risk 
management process.

Nostrum uses several metrics across the 
transition and physical risks spectrum to 
assess climate-related risks. For climate 
change our key risk metric is focusing on 
carbon emissions, air quality and flaring 
frequency. All of these are measured, 
managed and reported to the Board with a 
specific KPI around reduction in GHG (see 
(c) below). Beyond KPIs we have identified 
certain activities and projects to help 
reduce emissions that have included but 
are not limited to reducing vehicles at head 
office and encouraging the sharing of 
vehicles, eliminating taking private vehicles 
to the field by making buses mandatory, 
promoting work from home and electricity 
replacing diesel for heaters, boilers and 
other devices.

Management of climate change-related 
risks and opportunities is incorporated  
into the overall remuneration of the  
senior management. Please refer to  
the Remuneration Committee Report  
for details on climate change KPIs.

Moving forwards, the Company intends  
to include carbon pricing into its  
economic evaluation of future investment 
opportunities both within Chinarevskoye 
and outside. Following a benchmarking 
analysis of our peers, majors in the sector 
and research on regional plans for carbon 
pricing, we will incorporate an appropriate 
carbon price (cost to the business) in our 
investment decisions – implicitly increasing 
the hurdle rate for project approvals. For 
more information, please see pages 66-72.

b)  Disclose Scope 1, Scope 2,  
and, if appropriate, Scope 3 
greenhouse gas (GHG) emissions, 
and the related risks.

c)   Describe the targets used by the 
organisation to manage climate-
related risks and opportunities and 
performance against targets.

In the Environment (GHG Emissions Results) 
section of this report, we disclose our 
Scope 1 and Scope 2 GHG emissions.

Scope 1 and Scope 2 GHG emissions have 
been reported on an annual basis in our 
Annual Report and Company website. The 
level of reporting has expanded in line with 
our commitment to being transparent to 
our stakeholders.

Furthermore, GHG emissions reporting is a 
State legislative requirement as required by 
the Republic of Kazakhstan (the country is 
in alignment with the GHG Protocol).

The Company in 2023, expanded its 
disclosure on Scope 3 and prepared an 
analysis and calculations for Scope 3 GHG 
emissions for three categories. In total 
Scope 3 emissions amounted to 1,869 tons 
of CO2 (‘Waste generated in operations’ – 
289 tons of CO2, ‘Capital goods’ – 150 tons 
of CO2 and Goods and Services’ – 1,430 
tons of CO2). In 2022 Scope 3 emissions 
amounted to 352 tons of CO2 for one 
category (‘Waste generated in operations’). 
Detailed results of Scope 3 calculations will 
be covered in CDP submission for 2023.

In 2023 the Company reported total Scope 
1 emissions in the amount of 180,136 tCO2e 
and total Scope 2 emissions of 21 tCO2e. 
For more information, please see  
pages 65-72 in the Strategic Report.  
With focus on reduction of emissions, it  
is our plan to continue to work with our 
contractors to identify energy efficient 
opportunities in their supply chain and 
assist them to implement sustainable 
initiatives. Internal focus is also placed on 
reducing emissions from business and 
commuting travel.

Nostrum is making efforts to not exceed the 
quota for greenhouse gas emissions set by 
Kazakhstan and sets this target as a KPI in 
the annual HSE plan in order to reduce the 
actual value of greenhouse gas emissions  
by 5% compared to the previous year. While 
our approved quota of GHG emissions for 
2023 was 206,650 tonnes of CO2, Nostrum 
set a goal of 5% year-on-year reduction  
of actual CO2 in 2023. The actual CO2 
emissions in 2023 were 176,277 tonnes and 
our actual GHG emissions in CO2 equivalent 
were 180,157 tonnes. The increase in 
emissions is explained is due to the re-start 
of GTU-3 during 2023 and, as a result, a 
higher fuel consumption requirement. For 
more information, please see pages 70-72.

In 2023 we significantly improved our ESG 
Risk Rating from the international agency 
Sustainalytics. Our current ESG Risk Rating is 
30.1 which places the Company on the very 
low end of the “High Risk” category, and 
only 0.1 point separate us from the “Medium 
Risk” category on the ESG Risk Rating scale. 
Nostrum has scored amongst the top 20 
companies within the Oil & Gas Exploration 
and Production industry assessed by 
Sustainalytics. In 2024 Nostrum plans to 
strengthen its ESG strategy around gas and 
cleaner energy mix to further improve the 
rating. See page 54 for more details.

We accept that the Group is on a journey 
towards net zero and will report through 
interim targets in forthcoming years.

We intend to be part of the solution for 
Kazakhstan’s strategy to transition to 
cleaner energy and achieve carbon 
neutrality by 2060.

This strategic report is approved by  
the Board.

STRATEGIC REPORT 
Introduction to corporate governance 

Introduction to corporate governance

Section 1: Board leadership 
and company purpose
A successful company is led by an effective 
and entrepreneurial Board, whose role is to 
promote the long-term sustainable success 
of the company, generating value for 
shareholders and contributing to wider 
society. See pages 84-85.

The Board establishes the company’s 
purpose, values and strategy, and satisfies 
itself that these and its culture are aligned. 
All directors must act with integrity, lead by 
example and promote the desired culture. 
See pages 60-63, 18-19.

The Board ensures that the necessary 
resources are in place for the company  
to meet its objectives and measures 
performance against them. The Board also 
establishes a framework of prudent and 
effective controls, which enable risk to be 
assessed and managed. See pages 32-33.

In order for the company to meet its 
responsibilities to shareholders and 
stakeholders, the Board ensures effective 
engagement with, and encourages 
participation from, these parties.  
See pages 20-21 and 86.

The Board ensures that workforce policies 
and practices are consistent with the 
company’s values and support its long-term 
sustainable success. The workforce is able 
to raise any matters of concern with the 
Board. See pages 60-63.

Section 2: Division of 
responsibilities
The chair leads the Board and is 
responsible for its overall effectiveness  
in directing the company. The chair 
demonstrates objective judgement and 
promotes a culture of openness and 
debate. In addition, the chair facilitates 
constructive Board relations and the 
effective contribution of all non- executive 
directors, and ensures that directors receive 
accurate, timely and clear information.  
See pages 90-92.

Section 3: Composition, 
succession and evaluation
Appointments to the Board are subject  
to a formal, rigorous and transparent 
procedure, and an effective succession 
plan should be maintained for Board and 
senior management. Both appointments 
and succession plans should be based on 
merit and objective criteria and, within this 
context, should promote diversity of 
gender, social and ethnic backgrounds, 
cognitive and personal strengths.  
See pages 91-92.

The Board and its committees have a 
combination of skills, experience and 
knowledge. Consideration should be given 
to the length of service of the Board as a 
whole and membership regularly 
refreshed. See pages 84-85 and  
committee reports.

Annual evaluation of the Board should 
consider its composition, diversity and how 
effectively members work together to 
achieve objectives. Individual evaluation 
should demonstrate whether each director 
continues to contribute effectively.  
See page 86.

The Board includes an appropriate 
combination of executive and non- 
executive (and, in particular, independent 
non-executive) directors, such that no one 
individual or small group of individuals 
dominates the Board’s decision-making. 
There is a clear division of responsibilities 
between the leadership of the Board and 
the executive leadership of the company’s 
business. See pages 90-92.

Non-executive directors should have 
sufficient time to meet their Board 
responsibilities. They provide constructive 
challenge, strategic guidance, offer 
specialist advice and hold management  
to account. See page 90-92.

The Board, supported by the company 
secretary, ensures that the company has the 
policies, processes, information, time and 
resources it needs in order to function 
effectively and efficiently. See pages 90-92.

Compliance with the Code
The UK Corporate Governance Code issued by the Financial Reporting Council in July 2018 (the “Code”) sets out the governance 
principles and provisions that applied to the Company until 31 May 2022, when the Company's listing category was transferred 
from “Premium Listing (commercial company)” to “Standard Listing (shares)”. A copy of the Code is available from the Financial 
Reporting Council’s website at www.frc.org.uk. The aim of the corporate governance report is to demonstrate how the principles  
of the Code have been considered and applied by the Company. The UK Financial Reporting Council promotes high-quality 
corporate governance and reporting through the Code with which all companies with a premium listing on the London Stock 
Exchange are required to either comply in full, or explain why, and to what extent, they do not comply. The Company intends to 
continue to comply with the Code or explain any non-compliance as it would if it were still premium listed. This statement should be 
read in conjunction with the Corporate Governance section of this report as a whole. The headings on this page and the following 
page correspond to the headings in the Code.

82  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

Section 4: Audit, risk and 
internal control
The Board should establish formal and 
transparent policies and procedures 
to ensure the independence and 
effectiveness of internal and external audit 
functions and satisfy itself on the integrity 
of financial and narrative statements.  
See pages 93-98.

The Board presents a fair, balanced and 
understandable assessment of the 
company’s position and prospects.  
See page 120.

The Board establishes procedures to 
manage risk, oversee the internal control 
framework, and determine the nature and 
extent of the principal risks the company is 
willing to take in order to achieve its 
long-term objectives. See pages 32-33.

Section 5: Remuneration
Remuneration policies and practices are 
designed to support strategy and promote 
long-term sustainable success. Executive 
remuneration is aligned to company 
purpose and values, and clearly linked to 
the successful delivery of the company’s 
long-term strategy. See pages 100-115.

A formal and transparent procedure  
for developing policy on executive 
remuneration and determining director 
and senior management remuneration 
should be established. No director  
is involved in deciding their own 
remuneration outcome. See pages 100-115.

Directors exercise independent judgement 
and discretion when authorising 
remuneration outcomes, taking account of 
company and individual performance, and 
wider circumstances. See pages 100-115.

Statement of compliance
Nostrum fully complied throughout 2023 
with the provisions of the 2018 version of 
the UK Corporate Governance Code 
except in the following respects:

Provision 12
The Board has not to date appointed one of 
the independent non-executive directors to 
act as the senior independent director, to 
provide a sounding board for the chair and 
serve as an intermediary for the other 
directors and shareholders. The Board 
believes that there are currently effective 
arrangements in place for communication 
between the chair and other directors and 
shareholders without such appointment.

Provision 21
As all members of the Board (with the 
exception of the Company’s CEO Arfan 
Khan) were appointed in February 2023, no 
formal evaluation of the Board or any of its 
committees took place in 2023. 

Provision 36
The Company’s LTIP has a total holding and 
vesting period of no more than three years 
and therefore does not comply with the 
requirements of Code Provision 36, which 
requires share awards to be released for 
sale on a phased basis and be subject to a 
total vesting and holding period of five 
years or more. As explained in the press 
release released by the Company on  
28 August 2019, a copy of which has also 
been published on the Public Register 
maintained by the Investment Association, 
the Board and the Remuneration 
Committee believe that the current 
provisions of the LTIP relating to the 
performance period and vesting period are 
appropriate and aligned with the interests 
of shareholders, so that modifying such 
provisions of the LTIP at this time would not 
be the right course of action. The full text of 
the announcement is available to read on 
the Company’s website.

CORPORATE GOVERNANCEBoard of Directors 

Board of Directors continued

Board activities and achievements during 2023
During the financial year, the Board held 7 meetings. The Board and Committee agendas were shaped to ensure that discussion was 
focused on the Group’s key strategies and monitoring activities, as well as reviews of significant issues arising during the year. The Group’s 
ongoing financial and strategic performance is reviewed at every meeting, and the Chief Executive Officer and the Chief Financial Officer 
comment on production, share price performance, the market and shareholder feedback.

The table below gives the highlights of how the Board and its committees spent their time during the 2023 financial year but should not 
be regarded as an exhaustive list. More information regarding the Group’s strategic objectives and focus during 2023 can be found in the 
Strategic Report on pages 1-81 and the more detailed activities of each Board committee are located in their relevant report.

Strategy and 
business focus

•  Discussions around the strategic options available to the Group to monetise the infrastructure through processing 

third-party volumes and acquisition of nearby, stranded assets such as Stepnoy Leopard.

•  Approved a targeted well workover and intervention programme.

Risk

•  Review of all interim financial results announcements and the 2022 Annual Report and Accounts.

•  Consideration of the Group’s going concern assessment, viability statement and risk appetite for the coming year.

•  Reviewed the Group’s liquidity forecast at each board meeting.

Governance

•  Received reports from Board committees.

•  Consideration of the UK Corporate Governance Code and other regulatory requirements for the Annual Report.

•  Review of the Notice of AGM and matters proposed for shareholder approval.

•  Reviewed and approved new and updated Group policies.

People and culture •  Board field trip and engagement with the local workforce.

Board evaluation
No formal Board evaluation took place in 2023 (the last Board evaluation took place in 2021) as all members of Board (with the exception 
of the Company’s Chief Executive Officer Arfan Khan) were appointed in February 2023. A board self-evaluation is currently being carried 
out for the 2023 calendar year.

Director induction and training
Each individual joining the Board receives a full, formal induction package with materials on the Group’s business and operational, 
financial and legal matters. They also meet with members of the Board in order to obtain a good understanding of the challenges and 
opportunities faced by the Group. The Directors are given the opportunity to discuss their training and professional development needs 
at every Board meeting and on an ad-hoc basis as required, and to make recommendations to the Chairman regarding topics on which 
they would like to receive training. In addition to training organised by the Company, the Directors regularly attend training events 
organised by third parties and the Company actively encourages Directors to attend such events.

Board policies and 
governance arrangements
Nostrum recognises the important role that 
good corporate governance plays in the 
success of the Company. As a result, the Board 
promotes high standards of corporate 
governance as a key component of its 
activities. Clearly defined roles and 
responsibilities, non-executive independence, 
boardroom and workplace diversity, an 
open and transparent culture and the work 
of our committees in implementing the 
Company’s values and policies throughout 
the Group are all vital ingredients to get this 
right for our stakeholders.

In order to ensure that it is involved in 
making important decisions for the  
Group and to ensure a clear division of 
responsibilities between the Board and 
executive management, the Board has 
identified certain “reserved matters” that 
are subject to its approval. Other matters, 
responsibilities and authorities have been 
delegated to its committees and the senior 
management team, as set out in the 
governance framework on pages 90-92.

The schedule of matters reserved for the 
Board is reviewed annually and is available 
on our website.

Division of responsibilities
On 27 November 2018, the Board resolved 
to expand the role of the Company’s 
Chairman, Atul Gupta, to give him certain 
executive responsibilities, in particular in 
relation to business development,  
strategic initiatives and investor relations. 
Notwithstanding this, in accordance with 
the Code, and with the exception of the 
period from 30 September 2020 to  
25 January 2021, the roles of Chairman and 
Chief Executive remained separate, with 
each having distinct and clearly defined 
responsibilities, as summarised in the 
Board structure diagram. Mr Gupta’s role as 
Executive Chairman was to guide, advise, 
counsel and assist the Chief Executive 
Officer in overseeing the Company’s 
implementation of its strategy. The Chief 
Executive remained responsible for line 
management of his direct reports and 
implementation of the Company’s strategy.

The Company’s Chairman as from  
14 February 2023, Stephen Whyte, is a 
non-executive director who also chairs the 
Company’s Strategy Committee.

The Chief Executive Officer is also a 
member of the Strategy Committee and

Independence
Robust oversight is crucial for strong 
corporate governance and the Board is 
committed to securing this through an 
appropriate balance of independent 
Non-Executive Directors.

other than the Chairman and Martin 
Gudgeon to be independent within the 
meaning of this term as defined in the Code.

Equality and diversity 
The Board has due regard for the 
importance of, and benefits from, diversity 
in its membership, including gender 
diversity, and strives to maintain an 
appropriate balance on the Board. The 
Board is composed of individuals with 
diverse sectoral experience, ages, 
geographic and ethnic origin, and gender.

As at 31 December 2023 the Company  
has 17% female representation on its 
Board. As at 2023 year-end, the Audit 
Committee comprises 33% females, the 
Nomination and Governance Committee 
has 20% female representation and 25% 
are females in the Remuneration 
Committee. The Nomination and 
Governance Committee remains satisfied 
that the Board has the right mix of skills and 
experience to operate effectively. However, 
the skills and experience mix will be 
revisited following the successful 
restructuring of the Existing Notes. The 
Nomination and Governance Committee 
remains committed to monitoring diversity 
closely as part of future succession 
planning.

On 7 December 2017, the Board  
approved its Equality and Diversity Policy. 
Clarificatory amendments were made to 
the Company’s Equality and Diversity  
Policy on 14 September 2022, to which  
the Company continued to adhere 
throughout 2023.

In accordance with the policy, the Group is 
committed to eliminating discrimination 
and encouraging equality and diversity in 
all of our business activities, including the 
provision of employment. The policy 
applies to all who work for the Group, 
including Directors, together with the 
managerial, supervisory and administrative 
bodies of all entities within the Group.

The policy also applies equally to the 
treatment of our supply chain, applicants 
and visitors by our staff and the treatment 
of our staff by these third parties. The 
objective of the policy is to promote 
equality of opportunity and to ensure  
that no individual suffers unlawful 
discrimination, directly or indirectly, on the 
grounds of race, colour, ethnicity, religion, 

sex, gender identity or expression, gender 
reassignment, national origin, age, marital 
status, disability or sexual orientation.

The Group aims to ensure the objective  
of the policy is met by:

•  Ensuring all recruitment advertising and 
publicity aims to encourage applications 
from any individual who has appropriate 
qualifications and/or experience;

•  Not offering discriminatory conditions  

of employment;

•  Ensuring all promotions are made strictly 
on the basis of the ability to do the job 
and no such decision is made on a 
discriminatory basis;

•  Considering requests for part-time work 
or job-sharing opportunities wherever 
appropriate and practicable, and aiming 
to ensure that part-time employees 
receive fair treatment;

•  Ensuring that the demands of religion 

(e.g. prayer time and religious holidays), 
culture (e.g. traditional dress) and special 
dietary needs are accommodated where 
possible; and

•  Taking reasonable steps to assist 

employees with domestic responsibilities 
(e.g. young children and dependent 
elderly relatives).

Throughout the year, our commitment to 
advancing diversity and inclusion within  
our organisation has remained a priority. 
We have enhanced and implemented 
several initiatives, notably the ‘Targeted 
Recruitment Program’, focusing on 
underrepresented groups such as women, 
minorities, and individuals with disabilities. 
Concrete measures as collaborating with 
external organisations, taking training for 
inclusive recruitment, and creating inclusive 
job advert have been taken. For more 
information on the Diversity Action Plan  
of the Group please see pages 61.

As at 31 December 2023, we did not 
comply with the following targets in the 
Listing Rules on board diversity:

•  40% of individuals on the board to be 

women.

•  At least one senior position (chair, chief 
executive, senior independent director  
or chief financial officer) to be held by a 
woman.

•  At least one individual be from an ethnic 

minority background.

Diversity data is collated by our HR function 
who request colleagues to self-report 
against drafts of this Annual Report.  
These targets were not met due to (a) the 
appointment processes which concluded  
on 14 February 2023 having failed to identify 
sufficient female candidates and (b) no 
member of the Board self-reporting as 
being from an ethnic minority background.

Bribery, corruption  
and whistleblowing
Bribery and corruption are 
significant risks in the oil and gas industry 
and, as such, the Company operates a 
Group-wide Anti- Corruption and Bribery 
Policy, which applies to all Group 
employees and contractor staff. The policy 
requires: annual bribery and corruption risk 
assessments; risk-based due diligence on 
all parties with whom the Company does 
business; appropriate anti-bribery and 
corruption clauses in contracts; and the 
training of personnel in anti-bribery and 
corruption measures. In addition, the 
Company’s Code of Conduct requires that 
employees or others working on behalf of 
the Company do not engage in bribery or 
corruption in any form. Corruption-related 
risks are evaluated on a Group-wide basis 
(not in respect of divisions). No confirmed 
corruption cases were identified in 2023.

Training on anti-corruption policies was 
undertaken in 2023.

The Company has also adopted a 
Whistleblowing Policy that takes account  
of the Whistleblowing Arrangements Code 
of Practice issued by the British Standards 
Institute and Public Concern at Work. 
Further information can be found on  
page 63.

No whistleblowing disclosures were 
reported in 2023.

Clarificatory changes were made to the 
Whistleblowing Policy on 17 August 2023.

Anti-facilitation of tax evasion
Further to the new rules under the Criminal 
Finances Act 2017 (CFA) in the UK, in 2018 
the Board approved a new Anti-Facilitation 
of Tax Evasion Policy applicable to the 
Group and its associated persons. In 
connection with the preparation of this 
policy, the Company commissioned an 
independent bespoke risk assessment and 
incorporated findings from the assessment 
into the policy.

No training on the anti-facilitation of tax 
evasion policy was undertaken in 2023.

Conflicts of interest  
GRI 2-15
Directors have a duty to avoid a situation  
in which they have, or may have, a direct  
or indirect interest that conflicts or may 
conflict with the interests of the Company.

Formal procedures are in place to ensure 
that the Board’s powers of authorisation  
of conflicts or potential conflicts of interest 
of Directors are operated effectively.

The Board is satisfied that during 2023 
these procedures were enforced and 
adhered to appropriately.

Appointment and tenure
All Executive Directors have service 
agreements with the Company. All 
Non-Executive Directors have letters of 
appointment with the Company. For all 
Executive Directors engaged through 
service agreements, there is no term limit 
on their services, as the Company proposes 
all Executive Directors for annual re- 
election at each subsequent Annual 
General Meeting of the Company.

Each Non-Executive Director appointment 
is for an initial term of three years, subject 
to being re-elected at each subsequent 
Annual General Meeting.

Financial Reporting Council (FRC) 
disclosure expectations
In October 2023, the Corporate Reporting 
Review (‘CRR’) team of the FRC highlighted 
a number of key matters for the 2022-2023 
financial reporting season. Top ten most 
common topics on which CRR team raised 
substantive questions with companies in 
their 2022/23 monitoring cycle were 
aligned to the following key areas of 
disclosure expectations for 2023/2024 
reporting cycle:

•  ensuring disclosures about uncertainty 

are sufficient to meet the relevant 
requirements and for users to understand 
the positions taken in the financial 
statements.

•  giving a clear description in the strategic 
report of risks facing the business, their 
impact on strategy, business model, 
going concern and viability, cross-
referenced to relevant detail in the 
reports and accounts.

•  providing transparent disclosure of the 

nature and extent of material risks arising 
from financial instruments.

•  providing a clear statement of 

The Committee considered the above-
mentioned expectations when reviewing 
the annual report and accounts, and 
addressed these while reviewing the annual 
report and accounts, as further described 
below in the next sections.

Self-assessment
No formal review of the Committee’s 
performance and effectiveness was made 
in 2023.

The Committee’s review of the quarterly 
results and half-yearly financial statements 
was done with an emphasis on ensuring the 
following:

•  Appropriateness of critical judgements 
and estimates applied by management 
(described in more detail below) and 
completeness of related disclosures;

•  Consistency of the adopted accounting 
policies with those used in prior periods;

Activities during the year
In accordance with its responsibilities 
outlined above, the Committee’s activities 
fall into the following four main areas, each 
of which is explained in more detail in the 
following sections 1 to 4:

1. Financial reporting

2. Risk management and internal controls

3. Compliance with laws and regulations

4. External audit

1. Financial reporting
The key areas of the Committee’s activities 
related to financial reporting can be 
summarised as follows:

•  Completeness of disclosures for 

compliance with financial reporting 
standards and relevant corporate 
governance requirements;

•  Assessment whether the Annual Report, 
taken as a whole, is fair, balanced and 
understandable, and provides the 
information necessary for the 
stakeholders to assess the Group’s 
performance, business model and 
strategy; and

•  Discussions on any significant matters 
with management and the external 
auditor and providing feedback to 
management on ways to improve the 
effectiveness and clarity of the Group’s 
corporate reporting.

The Committee reviewed this Annual 
Report with the same emphasis as noted 
above together with the specific areas 
noted by the FRC and outlined above.

Significant judgements, estimates and 
assumptions
Significant judgements, estimates and 
assumptions applied by management when 
preparing the financial statements are 
closely related to the principal risks and 
uncertainties faced by the Group, which  
are subject to constant monitoring by the 
Board and the Committee.

consistency with TCFD which explains, 
unambiguously, whether management 
considers they have given sufficient 
information to comply with the framework 
in the current year. 

•  Review of and discussions on the 

quarterly unaudited and annual audited 
financial statements and 
recommendation to the Board for 
approval;

•  performing sufficient critical review of the 
annual report and accounts, including: 
taking a step back to consider whether 
the report as a whole is clear, concise  
and understandable, omits immaterial 
information and whether additional 
information, beyond the requirements  
of specific standards, is required to 
understand particular transactions, 
events or circumstances; and a robust 
pre-issuance review to consider issues we 
commonly challenge including: internal 
consistency; whether accounting policies 
address all significant transactions; and 
presentational matters, such as cash flow 
and current/non-current classification.

•  Review of and discussions on the matters 
of liquidity and going concern analysis, as 
well as impairment considerations;

•  Review of annual budgets and quarterly 
performance and forecasts, and the 
status of key initiatives; and

•  Discussion of various ad-hoc matters 

related to financial accounting, reporting, 
treasury and tax, and other finance 
matters.

The other significant judgements, estimates and assumptions applied by management when preparing the financial statements, and the 
Committee’s responses, are noted in the following table:

Significant judgements

Significant estimates

Significant assumptions

Impact on financial 
statement accounts

VIABILITY AND GOING CONCERN ASSESSMENTS

One of the key judgements made by the 
management when preparing 2023 Annual 
Report and Accounts was related to the Group’s 
continued viability and going concern. Various 
risks and uncertainties may threaten the 
Company’s future performance and results. 

Committee actions

During 2023, the Committee continued to 
challenge management’s assessment that the 
Company and Group remain a going concern 
over a period of at least 12 months from the date 
of release of the financial statements and also 
viable over a period longer than 12 months. 

GEOPOLITICAL FACTORS

The Group’s operations are exposed to risks 
associated with the political and business 
environment in Kazakhstan, being the Group’s 
primary location of oil & gas operations, as well as 
its neighbouring countries. Severe sanctions and 
trade restrictions imposed by, among others, the 
US, UK and EU on Russia at various stages have 
increased the economic and political uncertainty 
and may have a material adverse impact on the 
Group’s business, results of operations, financial 
condition and prospects.

Committee actions

Changes in the significant estimates and key 
assumptions may affect the ability of the Group 
to continue as a going concern, or the level of 
impairment required against the CGU. 

Management uses internal 
estimates to forecast future 
volumes of oil and gas 
production, as well as opex, 
G&A, and capital expenditure 
for future periods, which are 
subject to various 
uncertainties.

The Committee reviewed the 
Management’s analysis of the 
Group’s cash flows for the 
12-36 months, and monitoring 
of the Group’s liquidity 
position, sensitivity tests of its 
liquidity position for changes 
in crude oil price, production 
volumes and timing of 
completion of various  
ongoing projects.

Management uses product 
price assumptions for crude oil, 
LPG, dry gas and stabilised 
condensate in order to estimate 
cash inflows from future 
product sales.

Conclusions based on the going 
concern and viability assessment 
affect the basis of preparation of 
the financial statements, and 
may lead to differing valuation 
and presentation of the items on 
the statement of financials.

The Committee reviewed the 
Management’s analysis of the 
Group’s cash flows for the 12-36 
months, and monitoring of the 
Group’s liquidity position, 
sensitivity tests of its liquidity 
position for changes in crude oil 
price, production volumes and 
timing of completion of various 
ongoing projects.

After careful consideration, the 
Committee is satisfied that the 
Group has sufficient resources  
to continue in operation for  
the going concern period to  
30 June 2025, and agrees with 
management’s conclusions in 
relation to the going concern 
(see page 46) and viability of the 
Group over a period of longer 
than 12 months (see pages 
39-40).

Estimations of the future prices 
for oil, oil products and dry  
gas as well as continued 
production from the 
Chinarevskoye field impact the 
calculation of future cash flows. 
In turn, these impact the 
assessment of the continued 
viability of the Company and 
Group as well as the level of 
impairment provision to  
be made.

In estimating recoverable 
amounts of the Group’s 
non-current assets the 
Management uses assumptions 
such future commodity prices, 
oil and gas reserves, future 
production profiles, operating 
expenses and capital 
expenditure estimates, fiscal 
regimes, and discount rates.

Changes in the significant 
estimates and key assumptions 
may affect the ability of the 
Group to continue as a going 
concern, or the level of 
impairment required against  
the CGU.

As part of the regular Board 
meetings, the Committee 
reviewed the monthly liquidity 
position prepared by 
management and agreed the 
estimations of product prices, 
costs and production profiles 
were appropriate.

As part of the regular Board 
meetings, members of the 
Committee considered and 
challenged the assumption that 
sanctions were not affecting 
marketing of the Group’s 
products or operations.

The Committee considered the 
impact of sanctions on the 
financial statements at the same 
time as it scrutinised the 
application of the going concern 
basis for the preparation of the 
quarterly, half -yearly and annual 
financial statements.

ACCOUNTING TREATMENT OF THE NOTES RESTRUCTURING

When reflecting the Notes Restructuring 
completed in February 2023, the Management 
applied judgement in determining whether the 
exchange of debt instruments was a substantial 
modification in the terms (see Note 13 to the 
consolidated financial statements) and whether 
the debt-to-equity swap met all criteria for 
application of IFRIC 19 Extinguishing Financial 
Liabilities with Equity Instruments (see Note 11 
 to the consolidated financial statements).

Due to the absence of 
observable market information 
for determining fair value of the 
SSNs and SUNs on the date of 
recognition, the Management 
estimated the discount rates 
applicable to these financial 
instruments to estimate their 
fair values through discounting 
future cashflows.

The Management applied 
certain assumptions when 
estimating the applicable 
discount rates for SSNs and 
SUNs, and used assumptions 
when constructing the future 
cashflows for the purpose of 
discounting for fair value 
estimation.

Committee actions

The Committee reviewed the Management’s 
analysis on exchange of debt instruments and 
debt-to-equity swap, and concurred with 
Management’s views and conclusions upon 
further discussions at committee meetings also 
taking into account the external auditors’ views.

The Committee reviewed the 
Management’s estimates of the 
discount rates and fair values of 
the bonds and concurred with 
the conclusions and results.

The Committee discussed  
with the Management the 
assumptions applied when 
estimating the discount rates 
applicable to the bonds, and 
future cashflows.

Significant estimates, 
assumptions and judgments 
affect the accounting treatment 
of the debt exchange and 
debt-to-equity swap, and hence 
the amounts of the Notes on the 
statement of financial position, 
their fair value adjustment 
impact on the income statement 
amounts as well as its 
amortisation over the remaining 
life of the financial instruments.

Taking into account 
management’s analysis and 
conclusions, the Committee 
concurred with the adopted 
valuations and accounting 
treatment for restructuring of the 
bonds, and discussed with the 
management appropriateness 
and clarity of the disclosures.

Significant judgements

Significant estimates

Significant assumptions

NON-CURRENT ASSETS’ CARRYING VALUES

For impairment analysis, management used 
judgement and determined a single cash 
generating unit (CGU) within the Group’s 
non-current assets, which includes all assets 
related to Chinarevskoye field, gas treatment 
facilities and processing of hydrocarbons from 
Ural O&G. In addition, the management used 
judgement in determining the FVLCD of the CGU 
while making assumptions about market-
participant’s view on the value creating 
components of the CGU.

Estimations of the recoverable 
amount of the CGU were 
prepared by management 
based on the discounted cash 
flow model using significant 
assumptions as well as 
considering the value of the 
enterprise.

Assumptions used in 
estimating recoverable 
amounts included future 
commodity prices, oil and gas 
reserves, future production 
profiles, operating expenses 
and capital expenditure 
estimates, fiscal regimes,  
and discount rates.

Enterprise valuation 
considered the market value  
of the Group’s bonds and the 
Company’s shares.

Committee actions

The Committee concurred with management’s 
position in determining a single CGU for the 
majority of the Group’s non-current assets, and 
with relevant determinations of the value creating 
components of the CGU.

The Committee reviewed the 
management’s detailed reports 
on impairment testing, and 
agreed with using a 
combination of a discounted 
cash flow model and enterprise 
value for impairment testing. 

The Committee reviewed the 
assumed product prices, 
discount rates, production 
profiles, and forecast capital 
and operating expenditures, 
and their consistency with 
other areas of future cashflow 
forecasts.

OIL AND GAS RESERVES

Management applied significant judgement 
when selecting the volume of future production 
used in the unit-of-production method of 
depletion of assets based on the oil and gas 
reserves.

Committee actions

The Committee concurred with the continued 
application of the unit-of-production method of 
assets depletion, as this method reflects the 
expected pattern of consumption of future 
economic benefits by the Group.

Management uses internal 
estimates to perform an annual 
assessment of the oil and  
gas reserves. The reserves 
estimates are made in 
accordance with the 
methodology of the Society of 
Petroleum Engineers (SPE).  
The estimates made as of  
31 December 2022 were 
audited by Ryder Scott.

Considering the most recent 
available information, the 
Committee reviewed various 
key assumptions used by 
management in estimating the 
oil and gas reserves and was 
satisfied with the 
reasonableness of such 
assumptions.

The Committee gained comfort 
on the outcomes of the oil and 
gas reserves’ estimations based 
on the key assumptions 
consistent with previous year’s 
estimations, which were audited 
by Ryder Scott.

The Committee reviewed the 
assumed product prices, 
discount rates, production 
profiles, and forecast capital 
and operating expenditures, 
and their consistency with 
other areas of future cashflow 
forecasts.

Impact on financial 
statement accounts

Changes in the key assumptions 
and market valuations may 
significantly affect the estimation 
of the recoverable amount of 
non-current assets, and 
consequently may result in 
impairment of non-current 
assets in the future periods.

After reviewing the management 
analysis and particularly 
considering the sensitivity 
analysis, the Committee 
concurred with he 
Management’s findings and 
conclusions on impairment 
testing, and also scrutinised the 
relevant disclosures in this 
report.

The Committee remained 
comfortable with the updated 
reserves estimations prepared 
by the Management, which are a 
central element in the calculation 
of depreciation, depletion and 
impairment.

After reviewing the management 
analysis and particularly 
considering the sensitivity 
analysis, the Committee 
concurred with he 
Management’s findings and 
conclusions on impairment 
testing, and also scrutinised the 
relevant disclosures in this 
report.

TAXATION

Considering ongoing changes and varying 
interpretations of Kazakhstan’s tax legislation and 
regulations, the management has to exercise 
judgement to evaluate the exposures to the 
ultimate amount of any future taxes, penalties 
and interest, which may result from tax authorities 
disagreement with the positions taken by the 
Group.

Committee actions

The Committee was periodically updated by the 
management on any uncertainties surrounding 
the Group’s tax position, which were accordingly 
discussed both at the Committee and Board 
meetings.

The Group is subject to routine 
tax audits and a resulting 
process whereby tax 
computations are discussed 
with the tax authorities. Whilst 
the ultimate outcome of such 
tax audits and discussions 
cannot be determined with 
certainty, management 
estimates the amounts of taxes 
accruals and disclosures.

Assumptions used in 
estimating the amount of 
taxation which may become 
payable are based on 
professional advice and 
consideration of the nature of 
current discussions with the tax 
authorities.

Because of the uncertainties 
associated with Kazakhstan’s tax 
systems, the ultimate amount of 
taxes, penalties and interest, if 
any, may be in excess of the 
amount expensed to date and 
accrued at 31 December 2023.

The Committee reviews the 
detail of any significant matter 
under discussion with the tax 
authorities and considers the 
likelihood of taxes being 
payable. 

Areas of focus were the nature 
of current discussions with the 
tax authorities, the outcomes 
of previous similar discussions 
and the views of taxation 
specialists.

The Committee also gave 
special consideration to the 
disclosure of any significant 
uncertainty in the estimation  
of the tax due.

Other significant judgements and 
estimates
The decommissioning of oil and gas assets 
at the end of their economic lives, the 
provisioning for contingent and other 
liabilities, current and deferred income tax, 
and fair value of financial instruments are all 
areas that require management to use 
judgement and estimates. The Committee 
examined each of these issues and sought 
clarifications, as and when necessary, 
including discussions with the Company’s 
auditor.

Significant matters communicated by the 
external auditor
In addition to the significant judgements, 
estimates and assumptions identified 
above, the external auditor also highlighted 
revenue risk, where there is always an 
assumed risk of fraud through management 
override of controls. The Committee 
believes that the Group’s policies and 
internal controls sufficiently minimise the 
risks related to management’s ability to 
manipulate accounting records or to 
misappropriate assets.

2. Risk management and  
internal controls
The Committee continuously monitored 
the Group’s risk management systems, 
further information on which can be found 
in the Risk Management section on pages 
32-33.

In accordance with requirements of the 2018 Code relating to the viability statement, the 
Committee reviewed the impact and sensitivity analysis of such risks on the Group’s 
long-term viability. The principal areas of risk management assessed by the Committee  
are described in the table below.

Key areas of the Committee’s focus in relation to principal risks:

Geopolitical 
Risk

Liquidity and 
financial 
reporting

Oil and gas 
production 
rates

The Committee continued to oversee the management’s assessments 
and responses to the impact of worldwide sanctions on the operations 
the Group. Such responses included continued collating and regular 
updates of the lists of all persons/entities sanctioned in order to 
ensure Nostrum does not enter into transactions with any of the 
persons/entities on these lists. 

Throughout the year, and as explained in more detail elsewhere in this 
report, the Committee has been focused on reviews of the viability  
of the Group and the application of the going concern basis for 
preparing the financial statements.

The Committee recognises the oil and gas production volumes are 
subject to significant risks and uncertainties, and hence continued 
constant monitoring of the forecast production rates against actual 
rates. Periodic updates were reported by the management at the 
Committee meetings and Board meetings, and any material variances 
were discussed in details with the management.

Cyber security 

The Committee continued to review the Company’s and Group’s 
exposure to cyber-attacks and discussed with management the 
effectiveness of proposed actions to address such exposures.

Financial 
reporting 

The Committee seeks to ensure the accurate maintenance of 
accounting records and related transactions, and relevant disclosures, 
with particular attention to areas of significant judgements, 
estimations and assumptions which are inherently subject to 
significant risks and uncertainties. Such areas of focus included 
viability and going concern assessments, impairment, oil and gas 
reserves and production forecasts, taxation as described in the 
previous section.

Internal control system
The Group’s internal control system is 
aimed at mitigating risks and improving 
efficiency. These include:

•  Segregation of authorities and duties at 

various levels;

•  Policies and procedures covering 

Directors’ remuneration, compliance, 
accounting and reporting and health, 
safety and environment as described in 
the relevant sections of the Annual 
Report;

•  Training and internal communications; 

and

•  Continuous monitoring of short-term, 

medium-term and long-term planning, 
forecasting and decision-making 
processes.

In Committee’s view, the Group continued 
to maintain a robust and defensible 
systems of risk management and internal 
control, and the Committee made 
recommendations to senior management 
on further improvements as and when 
considered necessary.

Details of the procedures related to 
compliance control are set out below 
(including compliance liaison equivalent to 
a hotline). No instructions for any conflict of 
interest settlement or compliance control 
forms were in use in 2023. No sanctions or 
disciplinary actions were applied in respect 
of internal control in 2023.

Internal Audit
The primary role of the internal audit 
function is to assist the Board and senior 
management to protect the assets, 
reputation and sustainability of the 
organisation. This is achieved through:

•  Building strong and effective risk 

awareness within the Group;

•  Continuously improving risk 

management and control processes  
so that they operate effectively and 
efficiently, and reflect leading practice; 
and

•  Sharing best practice regarding risk 

management and assurance across the 
Group.

The Group does not at this time have a 
dedicated internal audit function. Instead, 
the Group outsources this work to 
specialists in relevant areas or engages 
internal resources on a case-by-case basis.

Also, one of the compensating measures is 
the Contracts Board comprising the Chief 
Executive Officer, the Chief Financial 
Officer and the Chief Operating Officer. 
The Contracts Board meets weekly and  
its purpose is to review and approve 
significant expenditure commitments.

Also, in the Committee’s view, the Group 
has sufficient internal processes providing 
assurance to the management, Audit 
Committee and the Board about the 
effectiveness of systems of internal control 
and risk management: for instance quarterly 
reports to the Board on operations, financial 
performance, liquidity, and legal issues and 
assurance provided by Quality, Health, 
Safety and the Environment (“QHSE”) 
Department.

CORPORATE GOVERNANCEAudit Committee report

3. Compliance with laws and 
regulations
The Chief Legal Officer and Company 
Secretary attends the Committee’s 
meetings, which allows the Committee  
to raise any concerns related to legal, 
compliance or whistleblowing matters  
and the status of any ongoing litigation.

UK Corporate Governance Code
The Committee was in compliance with  
the Code throughout 2023, except that  
(in breach of provision 21 of the Code)  
no formal review of the Committee’s 
performance and effectiveness was  
made in 2023.

Whistleblowing arrangements 
Nostrum has a Group Whistleblowing 
Policy and, to ensure that all Group 
employees have access to someone who 
can provide them with support and 
guidance, the Group has two compliance 
liaison officers: one English, Kazakh and 
Russian-speaking officer based in Uralsk 
and another Dutch- and English-speaking 
officer based in Brussels. The Audit 
Committee maintained close contact  
with the compliance liaison officers. No 
whistleblowing disclosures were reported  
in 2023.

4. External audit
Appointment of external auditor
On 6 March 2023, the Company announced 
that it had appointed MHA as auditors to 
the Group and Ernst & Young Kazakhstan 
as auditors of Zhaikmunai LLP. The 
appointment of MHA was confirmed at the 
Company’s 2023 annual general meeting 
on 30 June 2023. 

Non-audit services
The main principle of the Group’s policy on 
the provision of non-audit services by the 
external auditor is that non-audit services 
may only be provided by the external 
auditor where the external auditor 
maintains the necessary degree of 
independence and objectivity, and that 
standard supplier selection procedures are 
carried out.

Committee pre-approval is required before 
the external auditor is engaged to provide 
any permitted non-audit services (as 
defined in the policy) in addition to any 
other approvals required by the Board  
and management pursuant to powers 
delegated by the Board or Nostrum’s 
internal approvals policies.

The Committee monitors the external 
auditor to ensure that it does not provide 
non-audit services that are prohibited by 
the FRC and limits such services to due 
diligence services and other assurance 
services. The revised policy is available on 
the Group’s website at www.nog.co.uk and 
will be reviewed and amended as and  
when required.

Audit fees for 2023 totalled US$1,116 
thousand (2022: US$1,188 thousand).

A detailed breakdown of audit and 
non-audit fees for 2023 can be found in 
Note 29 to the consolidated financial 
statements of the Group on page 149.

By operating in accordance with the above 
policy and other practices established 
within the Group, the Committee was 
satisfied that adequate safeguards were 
in place to ensure the objectivity and 
independence of the external auditor.

Diversity
More information on the Group’s actions

Appointments, succession 
planning and evaluation 
Following the successful completion of 
restructuring in 2023, there were changes 
in the composition of the Board and 
appointments at the Board level. 
Succession planning was discussed in 
relation to the CFO, as set out in the 
principal agenda items above. An external 
search consultancy, Heidrick & Struggles, 
was used in relation to the appointment of 
the CFO. It has no other connection with 
the Company. No formal Board evaluation 
took place in 2023 due to the small amount 
of time that has elapsed since the current 
Board members were appointed. Both 
informal (internal) and formal (involving 
independent external support) Board 
evaluations are planned for 2024.

The gender balance of senior management 
and their direct reports is set out on pages 
60-61.

All Directors will stand for re-election at the 
2024 Annual General Meeting with the full 
support of the Board.

Key responsibilities of the Nomination and Governance Committee

The key responsibilities of the Committee in 2023 were to:

•  Lead the process for Board appointments and make recommendations to the Board 

regarding candidates for appointment or reappointment as Directors;

•  Monitor and make recommendations to the Board on Board governance and corporate 

governance issues, to enable the Board to operate effectively and efficiently;

•  Regularly review the structure, size and composition (including skills, knowledge and 

experience) of the Board;

•  Ensure that an annual review of the effectiveness of the Board, and each committee of the 
Board, and the contribution of each director is conducted every year, with an independent 
external review at least every three years;

•  Keep under review the leadership needs of the Company, both executive and non-executive, 
with a view to ensuring the continued ability of the Company to compete effectively in the 
marketplace;

•  Review annually the time required from Non-Executive Directors.
•  Review and approve changes to the Board’s governance guidelines, monitor the compliance 

with such guidelines and with applicable legal, regulatory and listing requirements and 
recommend to the Board such changes or additional action as it deems necessary;
•  Require Directors to obtain approval from the Board before undertaking additional  

external appointments.

The terms of reference of the Committee were approved at a meeting of the Board on  
26 April 2023. The key areas of responsibility of the Committee with effect from 26 April 2023 
are unchanged from those applying from 1 January 2023 to 26 April 2023.

More details on key responsibilities can be found in the Committee’s terms of reference, which 
are available on the Group’s website at www.nog.co.uk.

CORPORATE GOVERNANCERemuneration Committee report

Statement from the Remuneration 
Committee Chairman GRI 2-19

Our strategic targets all remain commercially 
sensitive and, therefore, have not been 
disclosed.

Mr Khan is the only person who served as 
an Executive Director during 2023 who has 
been assessed for a bonus against 
achievement of these KPIs. The assessment 
was prepared by the Remuneration 
Committee as a recommendation to the 
Board, and was considered and agreed by 
the Board (other than Mr Khan himself) on 
27 February 2024. It was determined that 
80% of the 2023 KPIs had been achieved 
over the year 2023 (GBP 360,000).

Production and cost KPIs were fully satisfied 
(40% out of a possible 40%), the strategic 
KPIs were entirely met (50% out of a 
possible 50%) and HSE KPIs were not met 
(0% out of a possible 10%). However, taking 
into account the unfortunate fatality case 
during 2023, the Committee assessed the 
HSE KPIs as minus 10%, giving an overall 
achievement of 80% bonus of base 
compensation for the Chief Executive 
Officer for 2023 (GBP 360,000).

In addition, in light of the Chief Executive 
Officer’s achievements in 2023 being 
critical to the success of the Company, the 
Committee awarded the Chief Executive 
Officer a special discretionary bonus in 
respect of 2023 equal to of 59.5% of his 
base compensation (GBP 267,750).

The 2024 key performance indicators for 
the CEO and senior managers were initially 
proposed by the CEO and then developed 
in consultation with the Remuneration 
Committee and were agreed by the Board 
(other than Mr Khan himself) on 20 March 
2024. Such KPIs are set out on page 108. 
Senior management, including the Chief 
Executive Officer and (when appointed) the 
Chief Financial Officer, are assessed for 
bonuses based on these KPIs. Certain KPIs 
relating to strategic objectives have been 
carried forward from 2023 but are still 
considered to be commercially sensitive 
and so have not been disclosed. It is our 
intention to publish these, together with the 
bonus outcome, as required in the first 
Directors’ Remuneration Report following 
their achievement.

The Committee also exercised its discretion 
in deciding not to make any awards under 
the LTIP in 2023 to any LTIP participants.

As regarding the Group’s personnel as a 
whole, the collective agreement with 
employees of the Company’s subsidiary 
Zhaikmunai LLP working in the RoK 
provides for annual indexation of salaries. 

Effective 1 January 2023 an increase of 20% 
was granted to employees who are paid in 
Kazakh Tenge to cover the increase in the 
cost of living there during 2022.

Neither of the Executive Directors (Atul 
Gupta and Arfan Khan) received any salary 
increase in 2023. Any increase set out in the 
single total remuneration table in relation 
to Atul Gupta relates to untaken holiday 
that was paid in lieu. Any increase set  
out in the single total remuneration  
table in relation to Arfan Khan relates to 
deterioration of USD (in which reporting is 
made) relative to GBP (in which Mr Khan  
is paid).

Fees payable to the independent non- 
executive Directors in 2023 were revised to 
$100,000 per annum, plus $10,000 per 
annum for chairmanship introduced from 
14 February 2023.

UK Corporate Governance Code
The Company complied with the provisions  
of the Code relating to remuneration 
throughout 2023. Further information on 
compliance with the Code can be found  
on pages 82-83.

The Committee has addressed the factors 
in Provision 40 of the Code as to clarity, 
simplicity, risk and predictability by refining 
the CEO’s KPIs applying in 2024 relative to 
those which applied in 2023 to (a) reduce 
ambiguity; and (b) increase the level of 
granularity.

Compliance statement
This report has been prepared in 
accordance with the UK’s regulations on 
remuneration reporting. The Companies 
Act 2006 requires the Company’s auditor to 
report to shareholders on certain parts of 
the Directors’ Remuneration Report and to 
state whether, in the auditor’s opinion, 
those parts of the report have been 
properly prepared in accordance with the 
above regulations. This Annual Statement 
and the Policy Report are not subject to 
audit. The sections of the Directors’ 
Remuneration Report that are subject to 
audit are indicated accordingly.

On behalf of the Committee, I would like to 
thank shareholders for their continuing 
support.

Chris Hopkinson 
Chairman, Remuneration Committee
Independent Non-Executive Director

18 April 2024

Dear shareholder,
I am pleased to introduce the Directors’ 
Remuneration Report, which has been 
approved by both the Remuneration 
Committee and the Board for the year 
ended 31 December 2023.

Remuneration Policy
The aim of our Remuneration Policy, 
amongst other things, is to align the 
remuneration of executives and senior 
management with the interests of the 
Company’s shareholders and to ensure that 
rewards are justified by performance.

As noted elsewhere in this Annual Report, 
in accordance with the Companies  
Act 2006 a resolution to approve the 
Remuneration Policy was submitted to 
shareholders for a binding vote at the 2023 
Annual General Meeting and was approved 
by 80.30% of votes cast.

Remuneration for 2023
The 2023 Directors’ Remuneration Report 
will also be subject to an advisory vote at 
our 2024 Annual General Meeting.

Further details of Executive Director 
performance against the 2023 KPIs can be 
found on pages 101-108. In setting these 
targets, the Committee focused on areas 
critical for the Company, which were:

•  Minimising annual decline of average 

sales volumes;

•  Reducing operational and G&A  

cash costs;

•  Pursuing strategic objectives to monetise 
the spare capacity within our world-class 
processing facilities;

•  Ensuring all of our operations are carried 

out as safely as possible; and

•  Actively managing our greenhouse gas 

emissions.

on remuneration GRI 2-19, 2-20

Remuneration Committee
The remuneration of the Chairman, the 
Chief Executive Officer, the Chief Financial 
Officer, the Company Secretary and all 
other senior members of executive 
management is determined by the 
Committee under delegated powers  
from the Board and in accordance with  
the Committee’s terms of reference. The 
Chairman and the executive members of 
the Board determine the remuneration of 
all Non-Executive Directors, including 
members of the Committees.

In accordance with the terms of reference, 
members of the Committee shall  
be appointed by the Board on the 
recommendation of the Nomination and 
Governance Committee in consultation 
with the Chair of the Committee. The 
Committee shall comprise at least three 
members, the majority of whom shall be 
INEDs and one of whom shall be the 
Warrant Director.

From 1 January 2023 to 14 February 2023 
the Committee was comprised solely of 
INEDs, and from 24 February 2023 the 
Committee was comprised of three INEDs 
and the Warrant Director.

The primary responsibilities of the 
Committee are set out in its terms of 
reference which are reviewed and updated 
annually, and which are available to 
download from the Company’s website. 
Alternatively, copies can be obtained on 
request from the Company Secretary.

When making recommendations to the 
Board regarding Executive Directors’ 
remuneration the Committee is able to 
consider corporate performance on 
environmental, social and governance 
issues and ensures that any incentive 
structures do not raise any environmental, 
social or governance risks by inadvertently 
motivating irresponsible behaviour.

The Committee held three meetings  
in 2023 and the attendance of each 
committee member at such meeting  
is shown on page 87.

The principal agenda items at the meetings 
were as follows:

Thomas Hartnett (Company Secretary).

Mr Khan and Mr Mychalkiw were consulted 
on the remuneration of the other senior 
members of executive management and on 
matters relating to the performance of the 
Company. The Company Secretary was 
consulted on regulatory requirements.

None of Mr Khan, Mr Mychalkiw and 
Mr Hartnett participated in decisions  
on his own remuneration.

Members of the Group’s human resources 
team may attend relevant portions of 
Committee meetings to ensure appropriate 
input on matters related to the remuneration 
of senior members of the executive 
management team below Board level.

Key responsibilities of the 
Remuneration Committee

The Committee’s key responsibilities 
include ensuring that:
•  Remuneration policy and practices of 
the Company are designed to support 
strategy and promote long-term 
sustainable success, reward fairly  
and responsibly, with a clear link to 
corporate and individual performance, 
having regard to statutory and 
regulatory requirements; and

•  Executive remuneration is aligned to 

company purpose and values and linked 
to delivery of the Company’s long-term 
strategy.

respect of 2023 or 2022.

3.   Awards made under the LTIP in 2017 have vested but no awards have been exercised by the Executive Directors in respect of such awards. No awards made under

4.  The Company did not operate a pension scheme for Executive Directors in 2023 or 2022 but may make a pension contribution or a payment in lieu of pension

Company. The total amount paid to Executive Directors in 2023 in lieu of pension contributions was 40,378 USD (2022: USD 39,154). Executive Directors are not 
entitled to any additional benefit if they retire early.

Notes on the single total figure of remuneration table
Base salaries
Executive Directors’ salaries were considered by the Committee at the time of appointment to post in 2020 and 2021.

When reviewing salaries, the Committee considered the provisions of the Remuneration Policy and the situation of the Company.

Annual bonus
In 2023, Mr Khan was the only Executive Director eligible for a bonus.

In accordance with the Remuneration Policy approved in 2023, the maximum annual bonus opportunity for Mr Khan in respect of 2023 
was 240% of base compensation.

All bonuses are discretionary and can be reduced from the maximum annual bonus opportunity level for reasons such as poor 
performance by the employee or due to disappointing financial performance of the Group as a whole.

The key performance indicators for annual cash bonuses for the Chief Executive Officer were as follows:

2023 bonus performance measures

NFA Operations and Costs

Achieve annual No-Further-Activity PDP volume available for sales from 7,793 boepd (0%) closer to P90 to 8,782 boepd (100 %) 
in the P50-10 range. Sliding scale.

New Gas-Lift Compressor: Safe startup without any major HSE incident (LTI & HiPo free). Fully operational: 100% by August-1 to 
0% by September 1. Sliding scale

GTU3 Commissioning & Startup: Safe startup without and major HSE incident (LTI & HiPO free)

UOG Tie-Back Startup of Nostrum's Scope (excludes UOG's scope): Safe startup without any major HSE incident (LTI & HiPO free)

NFA Cost Focus (Opex + G&A): 0% if any increases, 30% if flat, and 100% if lower by 1 $mln. Sliding Scale (excludes indexation)

Strategic Objectives

KPIs:

•  Reduce GHG emissions with 5% of 2022 actual CO2 equivalent level

•  Safety KPIs: LTI < 0.85 ; RTI < 0.75 ; TRIF < 1.9 ; Number of HSE stop cards > 1000 ; >60% participation of ZKM employees in

1.  In certain cases information on performance measures or targets has been omitted because it is commercially sensitive and disclosure of such information may not 

be in the Company’s interest. Such information may be reported in the subsequent annual report if the performance measure or target has been met and the 
Company considers that disclosure of such information at such time would not be contrary to the Company’s interest.

These bonus performance measures apply to the Chief Executive Officer only. No other director is eligible for any bonus payment relating 
to 2023 performance based on these performance measures.

The Committee considered the performance of the Chief Executive Officer in the period 1 January to 31 December 2023.

Production and cost KPIs were fully satisfied (40% out of a possible 40%), the strategic KPIs were entirely met (50% out of a possible 50%) 
and HSE KPIs were not met (0% out of a possible 10%). However, taking into account the fatality case, the Committee exercised its 
discretion and assessed the HSE KPIs as minus 10%, giving an overall achievement of 80% bonus of base compensation for the  
Chief Executive Officer for 2023 (GBP 360,000).

In addition in light of the Chief Executive Officer’s achievements in 2023 being critical to the success of the Company, the Committee 
awarded the Chief Executive Officer a special discretionary bonus in respect of 2023 equal to of 59.5% of his base compensation  
(GBP 267,750).

The Company may provide for clawback or withholding provisions regarding annual bonuses. Clawback and withholding provisions do 
apply to LTIP awards for which performance conditions have been satisfied. Except as stated in relation to the Phantom Share Option 
Scheme and the LTIP, there are no deferral periods, vesting periods or holding periods. There are no performance targets or measures 
relating to more than one financial year. 

NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023  103

CORPORATE GOVERNANCE 
Mr Richardson resigned as Chief Financial 
Officer and as a Director of the Company 
on 31 March 2020 and, in accordance with 
the terms of the Plan, all outstanding 
options lapsed on 30 March 2021.

No awards were made under the Plan in 
2023 (2022: nil). It is intended that following 
the restructuring, a new management 
incentive plan will be introduced which will 
replace the Plan going forward. Therefore, 
it is not currently envisaged to make any 
further awards under the Plan.

The Plan rules do not contain any malus or 
clawback mechanisms. However, should 
further awards be considered under the 
Plan, then management will require any 
recommendations by the Company to the 
option trustee of an option award to be 
made subject to an express right for the 
Company to suspend further vesting and to 
claw back unvested options previously 
awarded where there have been 
exceptional circumstances of misstatement 
or misconduct, misbehaviour, significant 
risk failures or material downturns in the 
Group’s financial performance prior to 
vesting.

Long-term incentive plan
On 24 August 2017, the Board approved 
the making of certain initial grants under 
the Company’s new long-term incentive 
plan (LTIP). Awards under the LTIP were 
made in 2017 and 2018 but no further 
awards were made in 2019, 2020, 2021, 
2022 or 2023.

In accordance with the LTIP rules, all 
outstanding options that had been issued 
to two Executive Directors, Mr Kessel and 
Mr Richardson, who left the Company on  
16 December 2019 and 31 March 2020, 
respectively, lapsed as of 16 December 
2019 and 30 March 2021, respectively.

All Non-Executive Directors who had been 
granted awards under the LTIP (including 
Atul Gupta) have formally renounced such 
awards and the Company has amended the 
terms of its LTIP to make Non-Executive 
Directors ineligible to participate in the LTIP.

2023 annual report on remuneration

Long-term incentive awards
In 2017, the Company implemented its new 
performance-based long-term incentive 
plan (LTIP) and granted additional awards 
on 28 November 2018.

The LTIP awards granted are based on 
performance over one calendar year,  
which is followed by an additional two-year 
holding period such that no awards may 
vest before the third anniversary of the date 
of grant.

The Committee decided not to make any 
awards in 2023, and so there is no information 
to be provided in relation to performance 
conditions for the reporting year.

Pension entitlements
The Company did not operate a pension 
scheme for Executive Directors in 2023 but 
may make a contribution to a private 
pension fund or a payment in lieu of 
pension contributions to Executive 
Directors, under their employment 
contracts as executives of the Group as 
opposed to under their service agreements 
as Directors of the Company.

Payments to past Directors
Following the end of his term of service on 
14 February 2023, Atul Gupta was paid  
12 monthly equal instalments in lieu of  
12 months’ notice and a payment of 
$3,462.00 in lieu of all accrued but unused 
holiday entitlement. No other payments 
were made to past directors of the 
Company during the year ended  
31 December 2023.

Payments for loss of office
No payments were made to Directors in 
2023 for loss of office.

Non-executive Director fees
From 1 January 2023 to 14 February 2023, 
Non-executive Director fees were 10K USD 
per month. On 14 February 2023, Non-
executive Director fees were revised  
as follows:

The Company has not been notified of any 
change in Directors’ shareholdings since  
31 December 2023.

Please refer to the text in the Remuneration 
Policy table on page 111 in relation to 
shareholding guidelines applicable to 
Directors.

No shares have been granted to Directors 
so there was no requirement on any 
Director to hold them in accordance  
with the guidelines. The Company’s sole 
Executive Director Arfan Khan did not hold 
any shares in 2023 as encouraged by the 
guidelines.

Phantom share option plan
The Company operates one non- 
performance-related phantom share option 
plan (the Plan). The Executive Directors 
eligible to participate in the Plan were 
Kai-Uwe Kessel and Tom Richardson. Each 
held options over Ordinary Shares of the 
Company, generally vesting over a five-year 
period, exercisable at either US$4.00 or 
US$10.00 per Ordinary Share and expiring 
10 years from the date of grant, pursuant to 
the Plan.

Mr Kessel left the Company by mutual 
consent on 16 December 2019 and, in 
accordance with the terms of the Plan, all 
outstanding options lapsed as at the  
same date.

Remuneration statistics and comparisons
The following performance graph shows the growth in value of a notional £100 invested in the Company since the premium listing of the 
Company compared with the growth in the FTSE 350 Oil & Gas Index over the same period. The Committee selected the FTSE 350 Oil & 
Gas Index as the most appropriate comparator as it feels that it is a broad-based index which includes many of the Company’s competitors.

History of Chief Executive Officer remuneration
The total remuneration figures compared with a respective maximum opportunity for the Chief Executive Officer during each of the last 
ten financial years are shown in the table below. Kai-Uwe Kessel was in the position for the period 1 January 2014 to 16 December 2019, 
Kaat Van Hecke was the Chief Executive Officer from 16 December 2019 to 31 August 2020 and Atul Gupta from 1 September to 
25 January 2021.

The total Chief Executive Officer remuneration figure for 2020 therefore includes all amounts paid to Kaat van Hecke for the period 
1 January 2020 to 31 August 2020 and Atul Gupta for the period 1 September 2020 to 31 December 2020 for Chief Executive Officer 
services provided to the Group. Mr Gupta remained as Executive Chairman throughout the period 1 September 2020 to 25 January 2021. 
Therefore, the amount attributed to his role as Chief Executive Officer is the incremental value in his remuneration only, which was the 
pension contribution.

Please refer to the single total figure of remuneration table on page 102 for more information.

1. Total CEO remuneration for 2014 includes remuneration from the exercise of share options.
2. These figures include a bonus amount of EUR 236,262 paid in 2015 in respect of 2014 performance. No bonuses were paid for 2015 performance.
3. The amounts published in 2021 in respect of payments to Kaat Van Hecke in 2019 have been corrected to include the amount of EUR 32,006 paid to her spouse in 2019.
4. The amounts published in 2021 in respect of payments to Kaat Van Hecke in 2020 have been corrected to include amount of EUR 423,031 paid to her spouse in 2020.
5. Kaat Van Hecke was Chief Executive Officer from 16 December 2019 to 31 August 2020. Atul Gupta discharged the role of Chief Executive Officer from 1 September 

2020 to 25 January 2021 but received no increment in salary, benefits or annual bonus as a result of assuming this role as well as that of Executive Chairman. 
Therefore, the figures for the remuneration of the Chief Executive Officer in 2019, 2020 and 2021 reflect only the amounts paid to Kaat Van Hecke (and her spouse) 
and Arfan Khan.

1. Amounts paid to the Executive Chairman in 2023 represent remuneration paid to Atul Gupta until 14 February 2023 and payments in lieu of 12 months’ notice as 

monthly equal instalments over 12-month period following the end of his term of service on 14 February 2023.

2. Kaat Van Hecke was Chief Executive Officer from 16 December 2019 to 31 August 2020. Atul Gupta discharged the role of Chief Executive Officer from 1 September 

2020 to 25 January 2021 but received no increment in salary, benefits or annual bonus as a result of assuming this role as well as that of Executive Chairman. 
Therefore, the figures for the remuneration of the Chief Executive Officer in 2019, 2020 and 2021 reflect only the amounts paid to Kaat Van Hecke (and her spouse) 
and Arfan Khan.

3. The CFO was not a Director in 2022 and 2023.
4. The amounts published in 2021 in respect of payments to Mr Richardson in 2020 have been corrected to include amounts paid to his spouse in 2020. The amounts 

for 2021 only include Chief Financial Officer’s compensation up until 30 August 2021, at which time the position was removed as an Executive Director.

Statement of 2022 Remuneration 
Policy implementation
The Company’s Remuneration Policy was

annually to ensure they remain appropriate. 
The Company’s bonus year runs from 
1 January to 31 December each year, with 
bonus amounts being determined between 
December and March and becoming 
payable between March and April of  
each year.

Remuneration in respect of 2024 will be 
consistent with the current policy described 
on pages 109-115 of the Company’s 2023 
annual report.

Salaries and service fees
The Group appointed a new Chief 
Executive Officer on 26 January 2021.  
As part of that process, the level of 
remuneration to be paid was agreed by the 
Committee and approved by the Board.

CORPORATE GOVERNANCE2023 annual report on remuneration

Annual bonus
In accordance with the remuneration policy approved at the 2023 AGM, the maximum Executive Director annual bonus opportunity in 
respect of 2023 was up to 40% of base compensation, subject to a maximum opportunity for the Company’s Chief Executive Officer, of an 
annual bonus of up to 240% of base compensation and a maximum opportunity of 100% of base compensation for the Company’s Chief 
Financial Officer (if a Director).

Annual performance will be assessed against a performance scorecard of which a portion is based on operational and financial measures, 
a portion on strategic objectives and a portion on HSE, social and governance objectives.

The Committee has compiled a list of suitable key performance indicators against which the performance of the Executive Directors will 
be measured at the end of 2024 to determine the annual bonus amounts payable to Executive Directors in 2025. Details of any non- 
commercially sensitive KPIs are set out below. 2024 performance will be measured against these key performance indicators and the 
Committee will consider such performance together with the Company’s financial position, in deciding whether and at what level to 
award.

1.  In certain cases information on performance measures or targets has been omitted because it is commercially sensitive and disclosure of such information may not 

be in the Company’s interest. Such information may be reported in the subsequent annual report if the performance measure or target has been met and the 
Company considers that disclosure of such information at such time would not be contrary to the Company’s interest.

The percentage result (from the above 
table out of 100%) will be applied to 100% 
of the Chief Executive Officer’s base 
compensation and may also be applied  
to a percentage up to the Chief Financial 
Officer’s maximum opportunity of 100%  
(if he is appointed as a Director). Currently, 
no other director is eligible for any bonus 
payment relating to 2024 performance 
based on these performance measures.

The CEO’s maximum possible total bonus 
opportunity for 2024 is 240% of base 
compensation and his bonus opportunity 
based on the performance measures in the 
table above is 100% of base compensation. 
If appointed to the Board, the CFO’s 
maximum possible total bonus opportunity 
for 2024 will be 100% of base compensation.

Phantom share option plan
The Committee does not envisage the 
award of any additional phantom share 
options to Executive Directors in 2024.

Long-term incentive plan
The Committee does not envisage any 
awards under the Company’s existing 
long-term incentive plan in 2024. Therefore, 
no performance conditions have been set 
for 2024.

Non-Executive Directors
From 1 January 2023 to 14 February 2023, 
Non-executive Director fees were 10K USD

Remuneration Policy
This part of the Directors’ remuneration 
report sets out the Remuneration Policy for 
the Company and has been prepared in 
accordance with the Companies Act 2006, 
the Large and Medium-sized Companies 
and Groups (Accounts and Reports) 
(Amendment) Regulations 2013, the UK 
Corporate Governance Code and the 
Listing Rules of the UK Listing Authority.

•  Align the remuneration of executives with 

the interests of the Company’s 
shareholders, and ensure that rewards 
are justified by performance;

•  Ensure that the pay of the Executive 

Directors takes into account: (i) pay and 
conditions throughout the Company; and 
(ii) corporate governance best practice, 
including health and safety, environmental, 
social and governance risks;

The Company’s current remuneration 
policy was approved by shareholders at  
the Company’s 2023 AGM. 

Policy coverage
This Policy applies to all payments to 
Directors of the Company from the date  
of the Company’s 2023 AGM and until the 
approval of a revised Remuneration Policy.

Policy objectives
This policy is designed to:

•  Provide that the Company may not make 

any LTIP awards to its Non-Executive 
Directors or Chairman;

•  Provide a structure and level of pay that 

attracts and retains high-calibre directors 
capable of delivering the Company’s 
strategic objectives;

•  Provide clear and transparent 

performance incentives in a manner that 
is consistent with best practice and 
aligned with the interests of the 
Company’s shareholders;

•  Allow for future bonuses to be paid in 
whole or part in deferred shares; and

•  Allow for pension contributions to 

Executive Directors for their services 
under service contracts up to a 10% 
maximum opportunity, or higher if 
required by applicable law.

Peer group
For the purposes of benchmarking 
appropriate compensation, the Committee 
currently regards the following companies 
as the most relevant peer group for 
Nostrum:

•  FTSE 350 companies of a similar size to 

Nostrum;

•  Oil and gas E&P companies globally 

which compete for scarce skills within the 
industry; and

•  Companies operating predominantly in 
the FSU which compete for expatriate 
and local staff.

Risk management
The Committee will review incentive 
arrangements regularly to ensure that they 
comply with the Group’s risk management 
systems, and that controls are operating 
effectively. The Committee also ensures 
that inappropriate operational or financial 
risk-taking is neither encouraged nor 
rewarded through the Company’s 
remuneration policies. Instead, a sensible 
balance will be struck between fixed and 
variable pay, short- and long-term 
incentives and cash and equity.

The Committee has access to the Audit 
Committee and senior executive 
management as and when required to 
discuss any matters of risk assessment.

Nostrum operates in an industry that is 
inherently subject to operational risks. 
Particular emphasis is therefore placed  
on ensuring that health and safety best 
practice is reinforced by this Policy.  
The Committee consults regularly to  
ensure that this is the case.

Ongoing review of Policy
The Committee will periodically review 
whether this Policy is operating appropriately. 
Any actions arising from this review will be 
assigned to an appropriate person with a 
deadline to report back to the Committee. 
The level and structure of the compensation 
system will also be reviewed annually by the 
Committee.

The annual bonus is generally determined by 
reference to performance in the prior calendar 
year.

Annual bonuses are generally paid sometime 
between April and August of each year.

Malus and clawback provisions apply to the award 
of annual bonuses such that Executive Directors 
may be liable to repay some or all of their annual 
bonus if there is a material misstatement of results, 
or error in calculation of any KPI, or serious 
misconduct. The discovery period is one year 
commencing on the date on which the bonus is 
determined.

NOSTRUM OIL

LONG-TERM 
INCENTIVE 
PLAN (LTIP)

To incentivise 
Executive

over a longer 
timeframe, and 
to increase 
their interest in 
the Company’s 
long-term 
business  
goals and 
performance 
through share 
ownership.

To help retain 
executives and 
other key 
employees, 
and align their 
interests with 
shareholders 
through 
building a 
shareholding in 
the Company.

200% of base salary 
in any financial year.

Awards of nominal-cost options are made at the 
sole discretion of the Committee.

It was anticipated that awards would be granted 
annually in the period 2017 to 2019 subject to 
annual performance conditions. Generally, awards 
have a one-year performance period attached to 
them and will not vest for an additional two years 
following the date on which the Committee 
determines whether or not a performance 
condition has been wholly or partly satisfied,  
such that no award may vest before the third 
anniversary of the date of grant.

The Committee has the discretion to decide, on  
or before the grant of an award, that a participant 
shall be entitled to receive dividend equivalents 
arising over the period between the grant date 
and the vesting date, with such amounts being 
payable in cash or shares in respect of shares 
which vest.

Malus and clawback provisions apply to the LTIP 
such that participants are liable to repay/forfeit 
some or all of their shares if there is a material 
misstatement of results, or error in calculation, or if 
there is serious misconduct. The discovery period 
is three years commencing on the date on which 
the award vests, which can be extended by the 
Committee for an additional two years if an event 
occurs which the Committee determines could 
result in the operation of recovery or withholding 
provisions.

Performance criteria

Key performance 
indicators against which 
the performance of the 
Executive Directors will be 
measured in the following 
year are determined at the 
end of each year and  
all non-commercially-
sensitive key performance 
indicators are disclosed  
in the Directors’ 
Remuneration Report. 
Any commercially 
sensitive performance 
measures will be 
disclosed retrospectively 
following completion of 
the relevant financial year.

Performance against key 
performance indicators 
for the previous year is 
also disclosed in the 
Directors’ Remuneration 
Report to show how the 
Board has determined 
Executive Director 
performance against the 
relevant key performance 
indicators for that year, 
and consequently the 
levels of annual bonus 
payable to the Executive 
Directors.

Performance measures 
are generally measured 
over one year though the 
Committee has the 
discretion to apply a 
longer performance 
period to awards.

The Committee has the 
discretion to set any 
performance condition 
attaching to awards 
granted under the LTIP.

Vesting of awards would 
ordinarily be based:

•  In part on average 

accrued sales volumes 
measured in barrels of 
oil equivalent per 
day; and

•  In part on reserves 

measurement on the 
basis of 2P barrels of oil 
per share.

All Executive Directors of the Company are eligible 
to participate in the Plan at the discretion of  
the Board.

Awards vest on the basis described in the notes on 
the following page.

Long-term objectives are to be reviewed at every 
Committee meeting to ensure that they are 
appropriate, relevant and rigorous.

Share awards made in future may be reduced at 
any time prior to vesting, at the discretion of the 
Committee, following events such as (but not 
restricted to) a material misstatement of results, 
failure of risk management, breach of health and

Phantom share option plan
The Company operates the Plan in 
accordance with the Plan rules, the Listing 
Rules, the Disclosure and Transparency 
rules and other applicable rules. In order  
to retain talent, options are generally 
granted in tranches exercisable at the 
following times:

•  As to 20% of the Ordinary Shares in 

respect of which an option is granted, 
from the first anniversary of the date  
of grant;

•  As to a further 20% of the Ordinary 

Shares in respect of which an option is 
granted, from the second anniversary  
of the date of grant;

•  As to a further 20% of the Ordinary 

Shares in respect of which an option is 
granted, from the third anniversary of  
the date of grant;

•  As to a further 20% of the Ordinary 

Shares in respect of which an option is 
granted, from the fourth anniversary of 
the date of grant; and

•  As to the remaining 20% of the Ordinary 
Shares in respect of which an option is 
granted, from the fifth anniversary of the 
date of grant.

The Board retains discretion over a number 
of areas relating to the operation and 
administration of the Plan, which include, 
but are not limited to: (i) who participates; 
(ii) the timing of the grant of an award; and 
(iii) the size of the award.

Dividend waiver
The trustee has agreed to waive any 
dividends on shares held under the Plan 
and the LTIP.

Treatment of existing 
arrangements
For the avoidance of doubt, authority is 
given to the Company to honour any 
commitments entered into with current or 
former Directors notwithstanding the 
approval of the Policy. This will last until the 
existing incentives vest (or lapse) or the 
benefits of any contractual arrangements 
no longer apply.

Remuneration scenarios for 
Executive Directors
The bar charts below provide estimates of 
the potential remuneration of the executive 
directors for 2024. 

Three scenarios are presented for each 
executive director which are based on the 
following assumptions:

The “minimum” columns are intended to 
show the fixed level of remuneration to 
which executive directors are entitled in 
2024 irrespective of performance levels, 
namely base salary, benefits using the 
details set out in the single-figure table 
provided on page 102 (which includes any 
payments made in lieu of benefits made 
under the executive directors employment 
contracts for their roles as executives of the 

Group and not under their service contracts 
as executive directors) and any payments 
made in lieu of the provision of a pension 
scheme (which are paid under the executive 
directors employment contracts for their 
roles as executives of the Group and not 
under their service contracts as executive 
directors). No bonus payments are 
assumed for minimum performance.

The “on target” scenario seeks to illustrate 
the remuneration the executive directors 
would receive if performance was in line 
with expectation.

The “maximum” columns illustrate total 
remuneration levels in circumstances where 
the variable elements pay out in full, namely 
an annual bonus payment of 240% for  
Arfan Khan, the Company’s Chief  
Executive Officer.

As stated above, no Executive Director 
participated in the LTIP or the Phantom 
Share Option Scheme in 2023 and the 
Board will not award any shares under the 
Phantom Share Option Scheme in 2024. 
The Committee does not envisage any 
awards under the Company’s existing 
long-term incentive plan in 2024. Therefore, 
no performance conditions have been set 
for 2024.

The Company may lawfully terminate any 
Executive Director’s employment in the 
following ways:

•  At any time upon 6 months’ written 

notice; and

•  Without notice in circumstances where 
the Company is entitled to terminate  
for cause.

The lawful termination mechanisms 
described above are without prejudice  
to the employer’s ability in appropriate 
circumstances to terminate in breach of  
the notice period referred to above, and 
thereby to be liable for damages to the 
Executive Director.

The Executive Directors are not permitted 
to take up any office or employment with, 
or have any direct or indirect interest in,  
any firm or company which is in direct or 
indirect competition with the Company  
or any other member of the Group, or  
any company in which any member of the 
Group has an interest, without the consent 
of the Board.

In addition, the Chief Executive Officer is 
subject to non-solicitation covenants in 
relation to Group companies for 12 months 
from the date of termination of his service 
contract.

Copies of the Executive Directors’ service 
agreements and the Non-Executive 
Directors’ letters of appointment are 
available for inspection at the Company’s 
registered office during normal business 
hours and at the Annual General Meeting.

Recruitment
The Committee expects any new Executive 
Directors to be engaged on terms that are 
consistent with this Policy, but the 
Committee acknowledges that it cannot 
always predict the circumstances under 
which any new Executive Director may be 
recruited and so, accordingly, in each case, 
the Committee will consider:

•  The objective of attracting, motivating 

and retaining the highest calibre 
directors in a manner that is consistent 
with best practice and aligned with the 
interests of the Company’s shareholders;

•  Salary, benefits, annual bonus and 

long-term incentives will be determined 
within the framework of the Remuneration 
Policy table on pages 109-111;

•  Where an individual would be forfeiting 

valuable remuneration in order to join the 
Company, the need to retain flexibility 
should be considered in order for the 
Committee to be able to set base salaries 
at a level necessary to facilitate the hiring of 
the highest calibre candidates, including 
awards or payments to compensate for 
remuneration arrangements forfeited  
on leaving a previous employer. The 
Committee would require reasonable 
evidence of the nature and value of any 
forfeited compensation and would, to  
the extent practicable, ensure any 
compensation awarded was no more 
valuable than the forfeited award;

•  Judgement will be exercised to 

determine the appropriate measure of 
compensation for any forfeited award by 
taking account of relevant factors such as 
the value of any lost award, performance 
conditions and the time over which they 
would have vested or been paid;

•  Where an existing employee of the 

Company is promoted to the Board, the 
Company will honour any commitment to 
remuneration made in respect of a prior 
role, including any outstanding awards of 
options under the Plan;

•  The need, in order to recruit the best 
candidates, for the Company to offer 
sign-on remuneration, the necessity and 
level of which will depend on 
circumstances; and

•  Where an individual is relocating in order 

to take up a role, the Company may 
provide certain one-off benefits 
including, but not limited to, reasonable 
relocation expenses, accommodation, 
housing allowance and assistance with 
visa applications.

In making any decisions on remuneration 
for new joiners (including NEDs), the 
Committee will endeavour to balance the 
expectations of shareholders with current 
market and corporate governance best 
practice and the requirements of any new 
joiner, and would strive to pay no more than 
is necessary to attract the right talent to  
the role.

Provision

Policy

Notice period and 
compensation for 
loss of office in 
service contracts

6 months’ notice from the Company to Arfan Khan.

Base salary is paid in line with the notice period. Notice period payments will either be made as normal  
(if the Executive Director continues to work during the notice period or is on gardening leave) or they will  
be made as monthly payments in lieu of notice (subject to mitigation if alternative employment is found).

Treatment of annual 
bonus on termination

No entitlement.

Treatment of 
unvested share 
option awards  
under the Plan

Treatment of 
unvested awards 
under the LTIP

An Executive Director’s awards will generally lapse to the extent they have not vested on the date of voluntary 
cessation of employment and any portion that remains outstanding but unexercised after 12 months following  
such cessation will lapse. Mr Khan did not participate in the Plan in 2023.

For a Director considered to be a “good leaver” before the original vesting date (including leaving the Company  
on retirement, redundancy, ill health, as a result of death in service or in other circumstances determined by the 
Committee), outstanding awards will be pro-rated for time and vest subject to performance on the original vesting 
date. For a director who is considered a “good leaver” after the original vesting date, any awards will remain 
exercisable for a period of 12 months commencing on the date of cessation. For a Director whose employment is 
terminated for any other reason, the award will lapse in full. Mr Khan did not participate in the LTIP in 2023.

In particular circumstances, an arrangement may be agreed to facilitate the exit of a particular individual. Any such arrangement would be 
made bearing in mind the desire to minimise costs for the Group and only in circumstances where it is considered in the best interests of 
shareholders.

Change of control
In accordance with the LTIP rules and the terms of the awards granted in 2017 and 2018 under the LTIP, if there is a sale of all or 
substantially all of the Company or the Company’s business in circumstances where such sale has been approved by a majority of 
shareholders and is at a price of $10 per share or more, then all awards granted will vest in full regardless of the achievement or otherwise 
of applicable performance conditions on the date of such event if they have not already vested, and all awards will remain exercisable for 
one month from such date. To the extent that any option is not exercised in such period, it shall lapse at the end of that period.

Non-Executive Directors
The Chairman and Executive Directors set the remuneration package for Non-Executive Directors in line with the Non-Executive Directors’ 
Remuneration Policy table and subject to the Company’s Articles of Association (the Articles).

Remuneration Policy for Non-Directors
Employees who are not directors are generally eligible for annual performance-based bonuses and may also be eligible for other bonuses 
at varying percentages of their base compensation. Some employees are also participants in the LTIP and Plan.

114  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

The Non-Executive Directors are not 
permitted to take up any office or 
employment with, or have any direct or 
indirect interest in, any firm or company 
that was in direct or indirect competition 
with the Company without the consent of 
the Board.

Upon termination of the appointment and 
where such termination is for any reason 
other than due to the Non-Executive 
Director’s gross misconduct, material breach 
of the terms of the appointment, act of fraud 
or dishonesty or wilful neglect of the 
Non-Executive Director’s duties, the Non- 
Executive Director is entitled to be paid a 
pro-rated amount of their fees in respect of 
the period between the beginning of the 
quarter in which termination took place and 
the termination date.

Otherwise, none of the Non-Executive 
Directors is entitled to any damages for loss 
of office and no fee is payable in respect of 
any unexpired portion of the term of the 
appointment.

The Company intends to comply with 
Provision 18 of the UK Corporate 
Governance Code and accordingly all 
Directors will stand for re-election by 
shareholders at future Annual General 
Meetings until the Board determines 
otherwise.

Statement of consideration of 
employment conditions elsewhere 
in the Company
We have not consulted with employees on 
the executive Remuneration Policy. 
However, when determining the Policy for 
Executive Directors we have been mindful 
of the pay and employment conditions of 
employees across the Group as a whole.

Statement of consideration of 
shareholder views
Senior executive management of the 
Company regularly meet with shareholders 
and solicit their views on the Company’s 
policies in relation to Director and 
Executive remuneration, and take such 
views into account when formulating 
remuneration policies and remuneration 
levels in specific cases.

Auditor
In accordance with section 418(2) of the

aware, there is no relevant audit information 
of which the Company’s auditor is unaware 
and (b) the Director has taken all the steps 
that he/she ought to have taken as a

The appointment of MHA as auditors to the

approval at the 2024 AGM.

Directors’ liabilities and 
indemnities
The Company maintains liability insurance 
for its Directors. All Directors are also in 
receipt of an indemnity from the Company 
under the Company’s Articles of 
Association (the Articles) in respect of  
(a) liability incurred by any Director due  
to negligence, default, breach of duty or 
breach of trust in relation to the affairs  
of the Company, or any subsidiary 
undertaking or (b) any liability incurred  
by any Director in connection with the 
activities of the Company, or any subsidiary 
undertaking, in its capacity as a trustee of 
an occupational pension scheme; in both 
instances to the extent permitted under the 
Companies Act 2006. Copies of the 
Company’s Articles are available on the 
Company’s website or at the Company’s 
registered office during normal business 
hours and will be available for inspection  
at the Annual General Meeting.

In May 2015, the Board approved a policy 
for the indemnification of Directors, officers 
and other designated beneficiaries and the 
entry by the Company into an accompanying 
deed of indemnity.

The policy clarifies that the Company  
will seek to provide the maximum 
indemnification and protection to Group 
Directors and officers permissible under 
applicable law, except in cases of fraud or 
wilful default, including but not limited to:

i.  providing compensation for losses 
suffered in the course of acting as a 
Director or officer in the interests of  
the Group,

ii. providing Directors and officers with 
quality external legal representation  
and external professional advisers,

iii. assisting Directors or officers with 

repatriation following a third-party claim,

iv. continuing to make payment of a 

Director’s or officer’s remuneration and 
benefits while such Director or officer is 
under suspension, investigation or 
detention by order of a third party,

v.  taking reasonable steps to place any such 
Director or officer in a similar position 
working in another location or elsewhere 
in the Group which would allow his/her 
employment to continue and to 
compensate for any adverse financial 
consequences they incur as a result of 
their loss of office, or (vi) maintaining 
customary Directors’ and officers’ liability 
insurance policies.

The deed of indemnity is intended to cover 
any insufficiency in the protection granted 
to Directors and officers under the Articles 
which could expose such persons to 
substantial liability to third parties, 
including governmental authorities, in 
particular in jurisdictions where significant 
uncertainty exists in relation to the 
interpretation and application of the law. 
The deed of indemnity allows Directors, 
officers and other designated beneficiaries 
to enforce the protection provided for 
under the Articles without any further 
action by the Company being required.

CORPORATE GOVERNANCEDirectors’ report

Responsibility statement
The Directors are responsible for preparing 
the Annual Report and the financial 
statements in accordance with applicable 
law and regulations.

Company law requires the Directors to 
prepare such financial statements for each 
financial year that give a true and fair view 
of the state of affairs of the Group and the 
Company as at the end of the financial year, 
and of the profit or loss of the Group for the 
financial year. Under that law the Directors 
have elected to prepare the Group  
and Company financial statements in 
accordance with UK adopted International 
Accounting Standards. Under company law, 
the Directors must not approve the financial 
statements unless they are satisfied that 
they give a true and fair view of thestate  
of affairs of the Group and the Parent 
Company and of their profit or loss for  
that period.

In preparing these financial statements,  
the Directors are required to:

•  Select suitable accounting policies in 
accordance with IAS 8 Accounting 
Policies, Changes and Accounting 
Estimates and Errors and then apply  
them consistently;

•  Make judgements and accounting 
estimates that are reasonable and 
prudent;

•  Present information, including accounting 

policies, in a manner that provides 
relevant, reliable, comparable and 
understandable information;

•  State that the Group and the Company 
have complied with the UK adopted 
International Accounting Standards, 
subject to any material departures 
disclosed and explained in the financial 
statements;

•  Provide additional disclosures when 

compliance with specific requirements of 
IFRS is insufficient to enable users to 
understand the impact of particular 
transactions, other events and conditions 
on the Group’s and Company’s financial 
position and performance; and

•  Prepare the Group’s and Company’s 

financial statements on a going concern 
basis, unless it is inappropriate to do so.

Having taken all the matters considered by 
the Board and brought to the attention of 
the Board during the year into account,  
and having reviewed the Annual Report 
(including the Strategic Report), the 
Directors consider the Annual Report and 
Accounts, taken as a whole, to be fair, 
balanced and understandable, providing 
the information necessary for shareholders 
to assess the Company’s position and 
performance, business model and strategy.

The Directors have responsibility for:

•  Ensuring that the Company and the 

Group keep accounting records which 
disclose with reasonable accuracy the 
financial position of the Company and the 
Group and which enable them to ensure 
that its financial statements and Directors’ 
Remuneration Report comply with the 
Companies Act 2006;

•  Taking such steps as are reasonably open 
to them to safeguard the assets of the 
Group and to prevent and detect fraud 
and other irregularities; and

•  The maintenance and integrity of the 

corporate and financial information on 
the Company’s website.

Each of the Directors whose names and 
functions are listed on pages 84-85 
confirms, that to the best of their 
knowledge:

•  The Company and Group financial 

statements, which have been prepared  
in accordance with the UK adopted 
International Accounting Standards,  
give a true and fair view of the assets, 
liabilities, financial position and profit  
or loss of the Company and the 
undertakings included in the 
consolidation taken as a whole;

•  The Strategic Report contained in the 
Annual Report includes a fair review of 
the development and performance of  
the business and the position of the 
Company and the undertakings included 
in the consolidation taken as a whole, 
together with a description of the 
principal risks and uncertainties that  
they face; and

•  The Annual Report and financial 

statements, taken as a whole, are fair, 
balanced and understandable and 
provide the information necessary for 
shareholders to assess the Company’s 
position and performance, business 
model and strategy.

how our audit addressed the key audit 
matters, the terms “we” and “our” refer to 
MHA. The Group financial statements, as 
defined below, consolidate the accounts of 
Nostrum Oil & Gas plc and its subsidiaries 
(the “Group”). The “Parent Company” is 
defined as Nostrum Oil & Gas plc, as an 
individual entity. The relevant legislation 
governing the Company is the United 
Kingdom Companies Act 2006 
(“Companies Act 2006”).

Opinion
We have audited the financial statements of 
Nostrum Oil & Gas plc for the year ended 
31 December 2023. 

The financial statements that we have 
audited comprise:

•  the Consolidated Statement of Financial 

Position;

•  the Consolidated Statement of 

Comprehensive Income;

•  the Consolidated Statement of Cash 

Flows;

•  the Consolidated Statement of Changes 

in Equity;

•  Notes 1 to 32 of the consolidated 

financial statements, including significant 
accounting policies;

•  The Parent Company Statement of 

Financial Position;

•  the Parent Company Statement of Cash 

Flows;

•  the Parent Company Statement of 

Changes in Equity; and

•  Notes 1 to 16 of the company financial 

statements, including significant 
accounting policies.

The financial reporting framework that has 
been applied in the preparation of the 
Group and Parent Company’s financial 
statements is applicable law and 
International Financial Reporting Standards 
for use in the United Kingdom (“UK 
adopted IFRS”).

In our opinion the financial statements: 

•  Auditing the key factors and assumptions 

•  give a true and fair view of the state of the 
Group’s and of the Parent Company’s 
affairs as at 31 December 2023 and of the 
Group’s profit for the year then ended;

•  have been properly prepared in 

accordance with UK adopted IFRS; and

•  have been prepared in accordance with 
the requirements of the Companies  
Act 2006.

Our opinion is consistent with our reporting 
to the Audit Committee.

Basis for opinion
We conducted our audit in accordance with 
International Standards on Auditing (UK) 
(ISAs (UK)) and applicable law. Our 
responsibilities under those standards  
are further described in the Auditor 
Responsibilities for the Audit of the 
Financial Statements section of our report. 
We are independent of the Group in 
accordance with the ethical requirements 
that are relevant to our audit of the financial 
statements in the UK, including the FRC’s 
Ethical Standard as applied to listed public 
interest entities, and we have fulfilled our 
ethical responsibilities in accordance with 
those requirements. We believe that the 
audit evidence we have obtained is 
sufficient and appropriate to provide  
a basis for our opinion.

Conclusions relating 
to going concern
In auditing the financial statements, we 
have concluded that the Directors' use  
of the going basis of accounting in the 
preparation of the financial statements is 
appropriate.

Our evaluation of the Directors’ assessment 
of the Group’s and the Parent Company’s 
ability to continue to adopt the going 
concern basis of accounting included:

•  Determining if the directors’ process was 
sufficiently rigorous to support the going 
concern assessment;

•  Obtaining the directors’ going concern 
assessment, including the cash flow 
forecast for the period covered by the 
going concern assessment to 30 June 
2025. The directors have modelled a 
number of adverse scenarios in order  
to incorporate unexpected changes to 
the forecast liquidity of the Group.  
We evaluated the sufficiency of the 
sensitivities performed, in particular 
whether the adverse scenarios met the 
severe but plausible test;

adopted in the assessment of going 
concern and the cash flow model, 
including considering whether 
management had exercised any bias  
in selecting their assumptions, by 
comparing against past performance  
and available market data; 

•  Assessing the appropriateness of the 

method used to calculate the cash flow 
forecast. We tested the methodology  
and calculations; 

•  Checking the consistency of the factors 
and assumptions adopted in the going 
concern assessment with other areas of 
our audit, including the oil and gas asset 
impairment test; 

•  Considering the results of the reverse 

stress test in order to identify what factors 
would lead to the Group utilising all 
liquidity during the going concern 
period. We assessed the likelihood of 
these factors in the context of the outlook 
for commodity prices and against historic 
market lows as well as our own industry 
experience; 

•  Challenging the impact of the Russia/ 
Ukraine war on the going concern 
conclusion, including whether this 
threatened the Group’s ability to achieve 
forecast production and cash flows, 
whether there had been a loss of 
suppliers or customers, or whether 
sanctions inhibited the Group’s ability  
to execute the restructuring; and; 

•  Considering whether management’s 
disclosures in the Annual Report and 
Accounts were appropriate.

Based on the work we have performed,  
we have not identified any material 
uncertainties relating to events or 
conditions that, individually or collectively, 
may cast significant doubt on the Group’s 
and Parent Company’s ability to continue  
as a going concern for a period of at least 
twelve months from when the financial 
statements are authorised for issue. 

In relation to the Group’s reporting  
on how it has applied the UK Corporate 
Governance Code, we have nothing 
material to add or draw attention to in 
relation to the Directors’ statement in the 
company’s financial statements about 
whether the directors considered it 
appropriate to adopt the going concern 
basis of accounting.

Our responsibilities and the responsibilities 
of the directors with respect to going 
concern are described in the relevant 
sections of this report.

Overview of our audit approach

Scope

Our audit was scoped by obtaining an understanding of the Group, including the Parent Company, and its environment, 
including the Group’s system of internal control, and assessing the risks of material misstatement in the financial 
statements. We also addressed the risk of management override of internal controls, including assessing whether  
there was evidence of bias by the directors that may have represented a risk of material misstatement.

We, and our component auditors acting on specific group instructions issued by us, undertook full scope audits on the 
complete financial information of 2 components; Zhaikmunai LLP and Nostrum Oil & Gas plc (Parent company), specified 
audit procedures on particular aspects and balances on another 5 components in Kazakhstan, the Netherlands and Belgium.

Key Audit Matters
Key Audit Matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements 
of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we 
identified. These matters included those matters which had the greatest effect on: the overall audit strategy; the allocation of resources  
in the audit; and directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial 
statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Key audit matter description

How the scope of our audit responded to the key audit matter

Oil and gas reserves are a material factor in 
computing depreciation, depletion and 
amortisation (the “DD&A”) and the 
decommissioning provision. 

We have performed, in conjunction with the component auditor, the following 
procedures in respect of the oil and gas reserve estimation:
•  Carried out walkthrough procedures and updated understanding the Group’s 

internal process and key controls associated with oil and gas reserves estimation.

Significant judgement and estimations are made 
by the management, which are potentially 
susceptible to management bias, and hence 
causing an impact on the financial statements  
due to the technical uncertainty in assessing 
reserves quantities.

There is also a risk that management may influence 
the significant judgements and estimates in 
respect of commercial assumptions in order  
to portray favourable reserves disclosure to  
the market.

•  Assessed the competence of internal management’s specialists, to satisfy 
ourselves that they are appropriately qualified to carry out the volume’s 
estimation.

•  Checked the source, completeness and accuracy of the data used to estimate.
•  Corroborated management’s commercial assumptions by checking that they lie 
within an acceptable range compared to publicly available benchmarks where 
available. 

•  Compared management’s internal assumptions to the latest plans and budgets 
for consistency and challenged management’s capabilities to execute on such 
plans by comparison to prior performance.

•  Validated that the updated reserves estimates were appropriately included in 

the Group’s consideration of oil and gas asset impairment testing, in accounting 
for DD&A and the determination of decommissioning dates.

•  Reviewed the accuracy of the reserves and resource estimates disclosure in the 

Annual Report

•  Obtained and recalculated management’s decommissioning provision 

assessment.

•  Critically assessed key inputs and challenge management’s assumptions and 

judgements for reasonableness and indictors of bias.

Impairment of oil & gas development and production fixed assets

Key audit matter description

How the scope of our audit responded to the key audit matter

There is a risk in management’s judgement made 
on the impairment or impairment reversal of oil 
and gas assets since the recoverable amount of 
the oil and gas assets is sensitive to the changes in 
key inputs and assumptions, which may include 
the estimation of future prices of oil, natural gas 
and related products, the discount rate applied to 
future cash flow forecasts and the assumptions 
relevant to production volumes.

There is also a risk that management may influence 
the significant judgements and estimates in 
respect of its key assumptions in order to 
understate the impairment charge to achieve  
a targeted result.

We have performed, in conjunction with the component auditor, the following 
procedures in respect of the impairment and production fixed assets:
•  Obtained and evaluated management’s assessment of indicators of 

impairment or impairment reversal.

•  Walked through the controls designed by the Group relating to the 

assessment of the recoverable amount of oil & gas assets for impairment.

•  Assessed whether the value in use (VIU) or the fair value less costs of 

disposal (FVLCD) represents the higher recoverable amount.

•  Verified the integrity of supporting discounted cash flow models with the 

assistance of experts.

•  Evaluated the oil & gas prices and discount rate assumptions by comparing 

forecast price assumptions to the latest market evidence available, 
including forward curves, brokers’ estimates and other long-term price 
forecasts; and benchmarking the discount rate to the risks faced by 
the Group.

•  Assessed the appropriateness of the oil and gas reserves and resources 

estimates and evaluated the risking factors applied in estimating the value 
associated with the contingent resources.

•  Challenged the valuation methodology for estimating the recoverable 

amount; specifically the value attributed to the contingent resources and 
the opportunity for utilising the spare GTU processing capacity, including 
the related judgements around risking.

•  Tested forecast cash flows by comparing the assumptions used within the 
impairment models to the approved budgets, business plans and other 
evidence of future intentions.

•  Compared the exchange rate assumptions to external market data.
•  Evaluated management’s sensitivity analysis in order to assess the potential 

impact of a range of reasonably possible outcomes. These sensitivities 
include adjustments to the discount rate, oil & gas prices, future production 
volumes, opex and capex assumptions.

Valuation of new Notes (SSNs and SUNs) and the accounting treatment of the debt to equity swap
In February 2023 the Group restructured its debt 
pursuant to the terms of the Scheme sanctioned 
by the Court on 26 August 2022. 

We have performed the following procedures in respect of the new Notes:
•  Obtained and reviewed management’s paper on the restructuring  

(project ‘Newport’).

As a result of implementation of the restructuring, a 
portion of the Group's Notes were exchanged for 
$250 million of Senior Secured Notes (SSNs) and 
$345 million of Senior Unsecured Notes (SSNs), 
while the remainder of the Existing Notes together 
with accrued but unpaid interest were converted 
into fully paid ordinary shares which were then 
subject, together with the existing ordinary shares 
to a share consolidation and sub division exercise.. 
The new Notes mature in June 2026.

Management judgement is required to determine 
if the new Notes are substantially different from the 
old Notes in line with IFRS 9 and therefore if these 
are recognised as a new liability.

•  Considered whether the derecognition criteria of IFRS 9 have been met, on 

the basis that the new loans include substantially different terms.

•  Considered the accounting treatment regarding the share capital issued in 
exchanged for debt and challenged the associated profit recognition and 
movement in reserves in accordance with IFRIC 19.

•  Considered the fair value of the share capital exchanged and challenged 
the accounting treatment of the share premium and share consolidation 
and sub division.

•  Assessed management’s fair value calculation of the new notes under  

IFRS 9, including reliance on management experts.

•  Assessed and interrogated supporting valuation models, including 

assessment of key inputs and management judgements.

•  Engaged an auditor’s expert to assist with the reviews of the valuation 

methodology and model.

•  Evaluated the appropriateness of financial statement disclosures.

No material issues 
have been identified 
from the audit 
procedures 
performed.

Our application of materiality 
Our definition of materiality considers the 
value of error or omission on the financial 
statements that, individually or in 
aggregate, would change or influence  
the economic decision of a reasonably 
knowledgeable user of those financial 
statements. Misstatements below these 
levels will not necessarily be evaluated as 
immaterial as we also take account of the 
nature of identified misstatements,  
and the particular circumstances of their 
occurrence, when evaluating their effect  
on the financial statements as a whole. 
Materiality is used in planning the scope  
of our work, executing that work and 
evaluating the results. 

Materiality in respect of the Group was set 
at US$949,000 (2022: US$2,300,000) which 
was determined based on 2.25% (2022: 2%) 
of the Group’s adjusted EBITDA (as defined 
on page 47). Adjusted EBITDA was deemed 
to be the appropriate benchmark for the 
calculation of Group materiality as this is a 
KPI for the Group in the assessment of the 
performance of management, and market 
and analyst commentary also uses EBITDA 
to comment on the performance of the 
Group. In our opinion this is therefore the 
benchmark with which the users of the 
financial statements are principally 
concerned.

Materiality in respect of the Parent 
Company was set at US$1,920,000  
(2022: US$8,900,000) determined on the 
basis of 1% (2022: 1%) of the Parent 
Company’s Equity. Component materiality 
for group purposes was set at US$500,000 
(2022: US$310,000)

Given the non-trading status of the parent, 
having a materiality based on 1% of Parent 
Company’s Equity is considered an 
appropriate approach to benchmarking 
materiality as this is primarily what the users 
of the financial statements are concerned 
with given the loan notes and conversion 
during the year. 

NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023  123

FINANCIALSIndependent auditors report

Component materiality was used by the 
auditors to cover the audit risk for the areas 
covering significant risk for misstatement.

Performance materiality is the application 
of materiality at the individual account or 
balance level, set at an amount to reduce, 
to an appropriately low level, the 
probability that the aggregate of 
uncorrected and undetected 
misstatements exceeds materiality for the 
financial statements as a whole. 

Performance materiality for the Group was 
set at US$570,000 (2022: US$1,380,000) 
and at US$1,152,000 (2022: US$5,340,000) 
for the Parent Company which represents 
60% (2022: 60%) of the above  
materiality levels.

The determination of performance 
materiality reflects our assessment of the 
risk of undetected errors existing, the 
nature of the systems and controls and the 
level of misstatements arising in  
previous audits. 

We agreed to report any corrected or 
uncorrected adjustments exceeding 
US$47,450 in to the Audit Committee as 
well as differences below this threshold that 
in our view warranted reporting on 
qualitative grounds. 

Overview of the scope of the 
Group and Parent Company audits
Our assessment of audit risk, evaluation of 
materiality and our determination of 
performance materiality sets our audit 
scope for each company within the Group. 
Taken together, this enables us to form an 
opinion on the consolidated financial 
statements. This assessment takes into 
account the size, risk profile, organisation / 
distribution and effectiveness of group-
wide controls, changes in the business 
environment and other factors such as 
recent internal audit results when assessing 
the level of work to be performed at each 
component.

In assessing the risk of material 
misstatement to the consolidated financial 
statements, and to ensure we had adequate 
quantitative and qualitative coverage of 
significant accounts in the consolidated 
financial statements, of the 14 reporting 
components of the group, we identified  
2 components in Kazakhstan and the UK 
which represent the principal business units 
within the Group.

Full scope audits – Of the 14 components 
selected, full scope audits of the complete 
financial information of 2 components; 
Zhaikmunai LLP Chinarevkoye field and 
Nostrum Oil & Gas plc were undertaken, 
these entities were selected based upon 
their size or risk characteristics. 

Limited scope audits – Specific procedures were undertaken on 5 components; Nostrum 
Oil & Gas Coöperatief UA, Nostrum Oil & Gas Finance B.V., Nostrum Services N.V., 
Nostrum Services N.V. – KZ Branch and Postiv Invest. Our audit work was executed  
at group materiality.

The group audit team led and directed the 
audit work performed by the component 
auditors in Kazakhstan and Belgium 
through a combination of group planning 
meetings and calls, provision of group 
instructions (including detailed 
supplemental procedures), review and 
challenge of related component interoffice 
reporting and of findings from their 
working papers, review of component 
auditors working papers, and interaction 
on audit and accounting matters which 
arose, which included assessing the 
appropriateness of conclusions and 
consistency between reported findings and 
work performed.

The control environment
We evaluated the design and 
implementation of those internal controls of 
the Group, including the Parent Company, 
which are relevant to our audit, such  
as those relating to the financial  
reporting cycle. 

Component IT audit specialists were 
engaged to get an understanding of the 
general IT environment and general IT 
controls for the businesses critical 
applications principally based in 
Kazakhstan.  

Climate-related risks
In planning our audit and gaining an 
understanding of the Group and Parent 
Company, we considered the potential 
impact of climate-related risks on the 
business and its financial statement. We 
obtained management’s climate-related 
risk information, along with relevant 
documentation relating to management’s 
assessment and held discussions with 
management to understand their 
processes for identifying climate-related 
matters.

We engaged specialists to assess, amongst 
other factors, the benchmarks used by 
management, the nature of the group’s 
business activities, its processes and the 
geographic distribution of its activities.

We designed audit procedures to 
specifically consider those assets and 
liabilities where we anticipated, based  

on the work performed, that the highest 
impact arising from climate change might 
fall. We have reviewed the information 
received by management and have not 
identified any additional climate related 
risks to be disclosed within the financial 
statements.

Reporting on other information 
The other information comprises the 
information included in the annual report 
other than the financial statements and our 
auditor’s report thereon. The directors are 
responsible for the other information 
contained within the annual report. Our 
opinion on the financial statements does 
not cover the other information and, except 
to the extent otherwise explicitly stated in 
our report, we do not express any form  
of assurance conclusion thereon. Our 
responsibility is to read the other 
information and, in doing so, consider 
whether the other information is materially 
inconsistent with the financial statements or 
our knowledge obtained in the course of 
the audit, or otherwise appears to be 
materially misstated. If we identify such 
material inconsistencies or apparent 
material misstatements, we are required to 
determine whether this gives rise to a 
material misstatement in the financial 
statements themselves. If, based on the 
work we have performed, we conclude that 
there is a material misstatement of this 
other information, we are required to report 
that fact.

We have nothing to report in this regard.

Strategic report and 
directors report 
In our opinion, based on the work 
undertaken in the course of the audit: 

•  the information given in the strategic 

report and the directors’ report for the 
financial year for which the financial 
statements are prepared is consistent 
with the financial statements; and 

•  the strategic report and the directors’ 

report have been prepared in accordance 
with applicable legal requirements. 

124  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

In the light of the knowledge and 
understanding of the Group and the Parent 
Company and their environment obtained 
in the course of the audit, we have not 
identified material misstatements in the 
strategic report or the directors’ report. 

Directors’ remuneration report 
Those aspects of the director’s 
remuneration report which are required  
to be audited have been prepared in 
accordance with applicable legal 
requirements. 

Corporate governance statement 
We have reviewed the directors’ statement 
in relation to going concern, longer-term 
viability and that part of the Corporate 
Governance Statement relating to the 
entity’s voluntary compliance with the 
provisions of the UK Corporate  
Governance Code. 

Based on the work undertaken as part of 
our audit, we have concluded that each of 
the following elements of the Corporate 
Governance Statement is materially 
consistent with the financial statements and 
our knowledge obtained during the audit: 

•  Directors' statement with regards the 

appropriateness of adopting the going 
concern basis of accounting and any 
material uncertainties identified set out 
on page 46; 

•  Directors’ explanation as to its 

assessment of the group’s prospects, the 
period this assessment covers and why 
the period is appropriate set out on  
page 46; 

•  Director’s statement on whether it has a 
reasonable expectation that the group 
will be able to continue in operation and 
meets its liabilities set out on page 46;

•  Directors' statement on fair, balanced 

and understandable set out on page 120; 

•  Board’s confirmation that it has carried 

out a robust assessment of the emerging 
and principal risks set out on page 32-33; 

•  Section of the annual report that 

describes the review of effectiveness of 
risk management and internal control 
systems set out on page 97;; and 

•  Section describing the work of the audit 

committee set out on pages 93-98.

Matters on which we are required 
to report by exception
We have nothing to report in respect of the 
following matters in relation to which the 
Companies Act 2006 requires us to report 
to you if, in our opinion: 

•  adequate accounting records have not 
been kept by the parent company, or 
returns adequate for our audit have not 
been received by branches not visited by 
us; or 

•  the parent company financial statements 
are not in agreement with the accounting 
records and returns; or 

•  certain disclosures of directors’ 

remuneration specified by law are not 
made; or 

•  the part of the directors’ remuneration 

report to be audited is not in agreement 
with the accounting records and returns; 
or 

•  we have not received all the information 

and explanations we require for our audit; 
or 

•  a corporate governance statement has 

not been prepared by the Parent 
Company. 

Responsibilities of directors 
As explained more fully in the directors’ 
responsibilities statement, the directors are 
responsible for the preparation of the 
financial statements and for being satisfied 
that they give a true and fair view, and for 
such internal control as the directors 
determine is necessary to enable the 
preparation of financial statements that are 
free from material misstatement, whether 
due to fraud or error. 

In preparing the financial statements, the 
directors are responsible for assessing the 
Group’s and the Parent Company’s ability 
to continue as a going concern, disclosing, 
as applicable, matters related to going 
concern and using the going concern basis 
of accounting unless the directors either 
intend to liquidate the Group or Parent 
Company or to cease operations, or have 
no realistic alternative but to do so. 

Auditor responsibilities for the 
audit of the financial statements 
Our objectives are to obtain reasonable 
assurance about whether the financial 
statements as a whole are free from 
material misstatement, whether due to 
fraud or error, and to issue an auditor’s 
report that includes our opinion. 
Reasonable assurance is a high level of 
assurance but is not a guarantee that an 
audit conducted in accordance with ISAs 
(UK) will always detect a material 
misstatement when it exists.

Misstatements can arise from fraud or error 
and are considered material if, individually 
or in aggregate, they could reasonably be 
expected to influence the economic 
decisions of users taken on the basis of 
these financial statements. 

A further description of our responsibilities 
for the financial statements is located on 
the FRC’s website at: www.frc.org.uk/
auditorsresponsibilities . This description 
forms part of our auditor’s report. 

Extent to which the audit was 
considered capable of detecting 
irregularities, including fraud
Irregularities, including fraud, are instances 
of non-compliance with laws and 
regulations. We design procedures in line 
with our responsibilities, outlined above, to 
detect material misstatements in respect of 
irregularities, including fraud.

These audit procedures were designed to 
provide reasonable assurance that the 
financial statements were free from fraud or 
error. The risk of not detecting a material 
misstatement due to fraud is higher than 
the risk of not detecting one resulting from 
error and detecting irregularities that result 
from fraud is inherently more difficult than 
detecting those that result from error, as 
fraud may involve collusion, deliberate 
concealment, forgery or intentional 
misrepresentations. Also, the further 
removed non-compliance with laws and 
regulations is from events and transactions 
reflected in the financial statements, the 
less likely we would become aware of it.

Identifying and assessing 
potential risks arising from 
irregularities, including fraud
The extent of the procedures undertaken to 
identify and assess the risks of material 
misstatement in respect of irregularities, 
including fraud, included the following:

•  We considered the nature of the industry 

and sector the control environment, 
business performance including 
remuneration policies and the Group’s, 
including the Parent Company’s, own risk 
assessment that irregularities might occur 
as a result of fraud or error. From our 
sector experience and through 
discussion with the directors, we 
obtained an understanding of the legal 
and regulatory frameworks applicable  
to the Group focusing on laws and 
regulations that could reasonably be 
expected to have a direct material effect 
on the financial statements.

•  We enquired of the directors and 

management and the Audit Committee 
concerning the Group’s and the Parent 
Company’s policies and procedures 
relating to:

•  identifying, evaluating and complying 

with the laws and regulations and 
whether they were aware of any 
instances of non-compliance;

•  detecting and responding to the risks 
of fraud and whether they had any 
knowledge of actual or suspected 
fraud; and

•  the internal controls established to 
mitigate risks related to fraud or 
non-compliance with laws and 
regulations.

NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023  125

FINANCIALSIndependent auditors report

•  We assessed the susceptibility of the 

financial statements to material 
misstatement, including how fraud might 
occur by evaluating management’s 
incentives and opportunities for 
manipulation of the financial statements. 
This included utilising the spectrum of 
inherent risk and an evaluation of the risk 
of management override of controls. 

•  As a result of these procedures we 

determined that the principal risks were 
management bias in accounting 
estimates, particularly in determining 
impairment of oil and gas reserves, and 
the potential for a breach of sanctions 
and/or counter sanctions related to the 
Russia and Ukraine conflict. The group 
engagement team shared this risk 
assessment with the Component 
Auditors of Significant Subsidiaries so 
that they could include appropriate audit 
procedures in response to such risks in 
their work.

Audit response to risks identified
In respect of the above procedures:

•  we corroborated the results of our 
enquiries through our review of the 
minutes of the Group’s and the Parent 
Company’s board meetings; 

•  we and the component auditors visited 
the operations in Kazakhstan observing 
operations and carrying out a physical 
verification of inventory and observed 
operations;

•  audit procedures performed by the 

engagement team in connection with  
the risks identified included:

•  reviewing financial statement 

disclosures and testing to supporting 
documentation to assess compliance 
with applicable laws and regulations 
expected to have a direct impact on  
the financial statements;

•  testing journal entries, including those 
processed late for financial statements 
preparation, those posted by 
infrequent or unexpected users, those 
posted to unusual account 
combinations;

•  evaluating the business rationale of 
significant transactions outside the 
normal course of business, and 
reviewing accounting estimates for 
bias;

•  enquiry of management around actual 

and potential litigation and claims;

•  challenging the assumptions and 

judgements made by management in 
its significant accounting estimates; 
and 

•  obtaining confirmations from third 

parties to confirm existence of a sample 
of year end balances.

•  we communicated relevant laws and 

regulations and potential fraud risks to all 
engagement team members, including 
experts, and the component auditors and 
remained alert to any indications of fraud 
or non-compliance with laws and 
regulations throughout the audit.

Other requirements 
We were appointed on 6 March 2023. The 
period of total uninterrupted engagement 
including previous renewals and 
reappointments of the firm is 2 years. 

We did not provide any non-audit services 
which are prohibited by the FRC’s Ethical 
Standard to the Group or the Parent 
Company, and we remain independent of 
the Group and the Parent Company in 
conducting our audit. 

Use of our report 
This report is made solely to the Parent 
Company’s members, as a body, in 
accordance with Chapter 3 of Part 16 of the 
Companies Act 2006. Our audit work has 
been undertaken so that we might state  
to the Parent Company’s members those 
matters we are required to state to them  
in an auditor’s report and for no other 
purpose. To the fullest extent permitted  
by law, we do not accept or assume 
responsibility to anyone other than the 
Parent Company and the Parent Company’s 
members as a body, for our audit work, for 
this report, or for the opinions we have 
formed.

Authority (FCA) Disclosure Guidance and

Nostrum Oil & Gas PLC and its wholly owned 
subsidiaries are hereinafter referred to as 
“the Group”. The Group’s operations comprise of a 
single operating segment including all Group’s 
assets related to its Chinarevskoye field, as well as 
surface facilities, and are primarily conducted 
through its oil and gas producing entity 
Zhaikmunai LLP located in Kazakhstan.  

Zhaikmunai LLP carries out its activities in 
accordance with the Contract for Additional 
Exploration, Production and Production-Sharing of 
Crude Hydrocarbons in the Chinarevskoye oil and 
gas condensate field (the “Contract”) dated 
31 October 1997 between the State Committee of 
Investments of the Republic of Kazakhstan and 
Zhaikmunai LLP in accordance with the license MG 
No. 253D for the exploration and production of 
hydrocarbons in Chinarevskoye oil and gas 
condensate field. 

The term of the Chinarevskoye subsoil use rights 
included a 5-year exploration period followed by a 
25-year production period with the Contract being 
valid until the end of 2031.  

As at 31 December 2023 the Group employed 571 
employees (31 December 2022: 566). 

On 14 October 2022, a new company Nostrum Oil 
& Gas Holding Limited was incorporated with a 
registered address of 20 Eastbourne Terrace, 
London, W2 6LG, UK. The entity is a wholly owned 
subsidiary of the Parent. 

On 12 December 2023, Nostrum Oil & Gas UK 
Limited was dissolved. 

On 17 July 2023, Nostrum Oil & Gas PLC acquired 
an 80% interest in Positive Invest LLP for US$20 
million. Positiv Invest LLP holds the rights to the 
Stepnoy Leopard Fields located in the West 
Kazakhstan region. The acquisition enhances 
Nostrum's ability to connect additional resources 
to their gas treatment facilities. The Stepnoy 
Leopard Fields are in proximity to Nostrum's 
existing operations and have a contract valid until 
December 2044. 

Zhaikmunai LLP is required to make monthly 
royalty payments throughout the entire 
production period, at the rates specified in the 
Contract.  

Royalty rates depend on hydrocarbons recovery 
levels and the phase of production and can vary 
from 3% to 7% of produced crude oil and from 4% 
to 9% of produced natural gas. Royalty is 
accounted on a gross basis. 

GGoovveerrnnmmeenntt  ““pprrooffiitt  sshhaarree””  

Zhaikmunai LLP makes payments to the 
Government of its “profit share” as determined in 
the Contract. The “profit share” depends on 
hydrocarbon production levels and varies from 
10% to 40% of production after deducting royalties 
and reimbursable expenditures. Reimbursable 
expenditures include operating expenses, costs of 
additional exploration and development costs. 
Government “profit share” is expensed as incurred 
and paid in cash. Government profit share is 
accounted on a gross basis. 

GGrroouupp  ddeebbtt  rreessttrruuccttuurriinngg  

On 31 March 2020, the Group announced that it 
would seek to engage with its bondholders 
regarding a possible restructuring of the Group’s 
US$725 million 8.0% Senior Notes due July 2022 
(“2022 Notes”) and its US$400 million 7.0% Senior 
Notes due February 2025 (“2025 Notes”) 
(together, the “Existing Notes”).  On 23 December 
2021, the Group entered into a lock-up agreement 
(the “First LUA”) and agreed terms of a 
restructuring with noteholders. The below outlines 
the key terms of the restructuring as agreed 
between the Group, acceded noteholders and ICU 
in the LUAs and also voted in favour of by Nostrum 
shareholders: 

Partial reinstatement of debt: 
• In the form of US$250 million Senior Secured 
Notes (SSNs) maturing on 30 June 2026 and 
bearing interest at a rate of 5.00% per year 
payable in cash. The SSNs are not convertible; 

113333   NNoossttrruumm  OOiill  &&  GGaass  PPLLCC 
132  NOSTRUM OIL & GAS PLC ANNUAL REPORT & ACCOUNTS 2023

• In the form of US$300 million Senior Unsecured 
Notes (SUNs) maturing on 30 June 2026 and 
bearing interest at a rate of 1.00% per year 
payable in cash and 13.00% per year payable in 
kind. If not repaid in cash at maturity, the SUNs 
are repayable in specie through the issuance of 
equity in the Company based on the value of 
the SUNs outstanding on the issuance date as a 
percentage of the fair market value of the 
Company (up to a maximum of 99.99% of the 
Company’s fully diluted equity); 

Conversion to equity:  
• Conversion of the remainder of the 

Existing Notes and accrued interest into 
equity by way of a UK scheme of 
arrangement:  

• Existing noteholders own 88.89% of the 
expanded ordinary share capital of the 
Company on closing of the restructuring. 
Existing noteholders also own warrants (to 
be held by trustee) allowing them to 
subscribe for an additional 1.11% of the 
ordinary share capital of the Company 
upon exercise – increasing noteholder 
ownership of the Company to 90.00%; 
• The existing ordinary shareholders will 

hold 11.11% upon closing of the 
restructuring. The existing ordinary 
shareholders will be diluted to 10.00% if 
the warrants held by existing noteholders 
are exercised; 

New corporate governance arrangements:  
• in respect of the Group and certain 

arrangements regarding future utilization of the 
Group's cashflows. This includes a cash sweep 
mechanism requiring that cash above US$30 
million is swept into a debt service retention 
account (to fund the next two cash interest 
payments due) and a restricted cash account 
which the Company can access with approval of 
the majority of Independent Non-Executive 
Directors of the Company; and 

• Transfer the Company's listing to the Standard 
Listing segment of the London Stock Exchange. 

Restructuring completion 
On 9 February 2023, the Restructuring was 
implemented on the key terms as agreed under 
Lockup Agreement, and pursuant to the terms of 
the Scheme sanctioned by the Court on 26 August 
2022. This led to the sub-division and consolidation 
of the Company's share capital, which resulted in a 
reduction of shares from approximately 1,693.8 
million to 169.4 million following a 10:1 
consolidation. By 10 February 2023, 150,563,304 
new shares were listed on the London Stock 
Exchange (ticker symbol NOG.L), and by 13 
February, also on the Astana International 
Exchange. The new notes and warrants were listed 
on The International Stock Exchange from 9 
February 2023, while no new securities were listed 
on Euronext Dublin. On 14 March 2023, the 
Company’s ordinary shares were delisted from the 
official list of the Kazakhstan Stock Exchange 
(KASE).

2.  Basis of preparation and consolidation 

BBaassiiss  ooff  pprreeppaarraattiioonn  

These consolidated financial statements for 
the year ended 31 December 2023 have been 
prepared in accordance with the UK adopted 
International Accounting Standards and the 
Companies Act 2006. The consolidated 
financial statements have been prepared 
based on a historical cost basis other than 
areas where accounting standards require an 
alternate measurement basis (Note 4). The 
consolidated financial statements are 
presented in US dollars and all values are 
rounded to the nearest thousand, except 
when otherwise indicated. The preparation of 
consolidated financial statements in 
conformity with IFRS requires the use of 
certain critical accounting estimates. It also 
requires from management to exercise its 
judgment in the process of applying the 
Group's accounting policies. The areas 
involving a higher degree of judgment or 
complexity, or areas where assumptions and 
estimates are significant to the consolidated 
financial statements are disclosed in Note 4. 
The Group recognises that there may be 
potential financial implications in the future 
from changes in legislation and regulation 
implemented to address climate change risk. 
Over time these changes may have an impact 
across a number of areas of accounting 
including asset impairment, increased costs, 
provisions, onerous contracts and contingent 
liabilities. However, as at the reporting sheet 

date, the Group believes there is no material 
impact on the balance sheet carrying values of 
assets or liabilities. This is not considered a 
significant estimate. 

BBaassiiss  ooff  ccoonnssoolliiddaattiioonn  

The consolidated financial statements 
comprise the financial statements of the 
Parent and its subsidiaries as at 31 December 
2023. Control is achieved when the Group is 
exposed, or has rights, to variable returns 
from its involvement with the investee and 
has the ability to affect those returns through 
its power over the investee. Specifically, the 
Group controls an investee if, and only if, the 
Group has:  
•  power over the investee (i.e., existing rights 
that give it the current ability to direct the 
relevant activities of the investee);  

•  exposure, or rights, to variable returns from 

its involvement with the investee;  
•  the ability to use its power over the 

investee to affect its returns.  

Generally, there is a presumption that a 
majority of voting rights results in control. To 
support this presumption and when the 
Group has less than a majority of the voting or 
similar rights of an investee, the Group 
considers all relevant facts and circumstances 
in assessing whether it has power over an 
investee, including:  
•  the contractual arrangement with the 
other vote holders of the investee;  

•  rights arising from other contractual 

arrangements;  

•  the Group’s voting rights and potential 

voting rights. 

The Group re-assesses whether or not it 
controls an investee if facts and circumstances 
indicate that there are changes to one or 
more of the three elements of control. 
Consolidation of a subsidiary begins when the 
Group obtains control over the subsidiary and 
ceases when the Group loses control of the 
subsidiary. Assets, liabilities, income and 
expenses of a subsidiary acquired or disposed 
of during the year are included in the 
consolidated financial statements from the 
date the Group gains control until the date the 
Group ceases to control the subsidiary. 

GGooiinngg  ccoonncceerrnn  

These consolidated financial statements have 
been prepared on a going concern basis. For 
more information on the going concern 
assessment of the Group please see page 46 
of the Annual Report. 

The directors are satisfied that the Group has 
sufficient resources to continue in operation 
for the foreseeable future, a period of not less 
than 12 months from the date of this report. 

Accordingly, they continue to adopt the going 
concern basis in preparing the consolidated 
financial statements.

3.  Changes in accounting policies and disclosures 

NNeeww  ssttaannddaarrddss,,  iinntteerrpprreettaattiioonnss  aanndd  
aammeennddmmeennttss  aaddoopptteedd  bbyy  tthhee  GGrroouupp  

The accounting policies adopted in the preparation 
of the financial statements are consistent with 
those followed in the preparation of the Group’s 
annual financial statements for the year ended 31 
December 2022, except for the adoption of new 
standards effective as of 1 January 2023. The 
Group has not early adopted any standard, 
interpretation or amendment that has been issued 
but is not yet effective. 

Several amendments apply for the first time in 
2023, but do not have an impact on the 
consolidated financial statements of the Group. 

IFRS 17 Insurance Contracts  

IFRS 17 Insurance Contracts is a comprehensive 
new accounting standard for insurance contracts 
covering recognition and measurement, 
presentation and disclosure. IFRS 17 replaces IFRS 
4 Insurance Contracts. IFRS 17 applies to all types 
of insurance contracts (i.e., life, non-life, direct 
insurance and re-insurance), regardless of the type 
of entities that issue them as well as to certain 
guarantees and financial instruments with 
discretionary participation features; a few scope 
exceptions will apply. The overall objective of IFRS 

17 is to provide a comprehensive accounting 
model for insurance contracts that is more useful 
and consistent for insurers, covering all relevant 
accounting aspects. IFRS 17 is based on a general 
model, supplemented by:  

• A specific adaptation for contracts with direct 
participation features (the variable fee approach)  

• A simplified approach (the premium allocation 
approach) mainly for short-duration contracts  
The new standard had no impact on the 
Group’s consolidated financial statements.  

Definition of Accounting Estimates - 
Amendments to IAS 8  
The amendments to IAS 8 clarify the distinction 
between changes in accounting estimates, 
changes in accounting policies and the 
correction of errors. They also clarify how 
entities use measurement techniques and 
inputs to develop accounting estimates.  
The amendments had no impact on the Group’s 
consolidated financial statements.  

Disclosure of Accounting Policies - 
Amendments to IAS 1 and IFRS Practice 
Statement 2  
The amendments to IAS 1 and IFRS Practice 
Statement 2 Making Materiality Judgements 

provide guidance and examples to help entities 
apply materiality judgements to accounting 
policy disclosures. The amendments aim to help 
entities provide accounting policy disclosures 
that are more useful by replacing the 
requirement for entities to disclose their 
‘significant’ accounting policies with a 
requirement to disclose their ‘material’ 
accounting policies and adding guidance on 
how entities apply the concept of materiality in 
making decisions about accounting policy 
disclosures.  
The amendments have had no impact on the 
Group’s disclosures of accounting policies, the 
measurement, recognition or presentation of 
any items in the Group’s financial statements.  

Deferred Tax related to Assets and Liabilities 
arising from a Single Transaction – 
Amendments to IAS 12  
The amendments to IAS 12 Income Tax narrow 
the scope of the initial recognition exception, so 
that it no longer applies to transactions that 
give rise to equal taxable and deductible 
temporary differences such as leases and 
decommissioning liabilities.  
The amendments had no impact on the Group’s 
consolidated financial statements.

Standards issued but not yet effective 
The new and amended standards and 
interpretations that are issued, but not yet 
effective, up to the date of issuance of the 
Group’s consolidated financial statements are 
disclosed below. The Group intends to adopt 
these new and amended standards and 
interpretations, if applicable, when they 
become effective.  

Amendments to IFRS 16: Lease Liability in a Sale 
and Leaseback 
In September 2022, the IASB issued 
amendments to IFRS 16 to specify the 
requirements that a seller-lessee uses in 
measuring the lease liability arising in a sale and 
leaseback transaction, to ensure the seller-
lessee does not recognise any amount of the 
gain or loss that relates to the right of use it 
retains. 
The amendments are effective for annual 
reporting periods beginning on or after 1 
January 2024 and must applied retrospectively 
to sale and leaseback transactions entered into 
after the date of initial application of IFRS 16. 
Earlier application is permitted and that fact 
must be disclosed. 

The amendments are not expected to have a 
material impact on the Group’s financial 
statements. 

Amendments to IAS 1: Classification of Liabilities 
as Current or Non-current 

In January 2020 and October 2022, the IASB 
issued amendments to paragraphs 69 to 76 of 
IAS 1 to specify the requirements for classifying 
liabilities as current or non-current. The 
amendments clarify: 
• What is meant by a right to defer settlement 
• That a right to defer must exist at the end of 
the reporting period 
• That classification is unaffected by the 
likelihood that an entity will exercise its deferral 
right 
• That only if an embedded derivative in a 
convertible liability is itself an equity instrument 
would the terms of a liability not impact its 
classification.  
In addition, a requirement has been introduced 
to require disclosure when a liability arising 
from a loan agreement is classified as non-
current and the entity’s right to defer 
settlement is contingent on compliance with 
future covenants within twelve months. 

The amendments are effective for annual 
reporting periods beginning on or after 1 
January 2024 and must be applied 
retrospectively. The Group is currently 
assessing the impact the amendments will have 
on current practice and whether existing loan 
agreements may require renegotiation. 

Supplier Finance Arrangements - Amendments to 
IAS 7 and IFRS 7 
In May 2023, the IASB issued amendments to 
IAS 7 Statement of Cash Flows and IFRS 7 
Financial Instruments: Disclosures to clarify the 
characteristics of supplier finance arrangements 
and require additional disclosure of such 
arrangements. The disclosure requirements in 
the amendments are intended to assist users of 
financial statements in understanding the 
effects of supplier finance arrangements on an 
entity’s liabilities, cash flows and exposure to 
liquidity risk. 
The amendments will be effective for annual 
reporting periods beginning on or after 1 
January 2024. Early adoption is permitted, but 
will need to be disclosed. 
The amendments are not expected to have a 
material impact on the Group’s financial 
statements. 

management concluded that transactions 
represents an asset purchase rather than a 
business combination. 

The difference between the purchase price of 
$19.3 million and the net book value of the assets 
and liabilities acquired was considered as the price 
paid for the subsoil use license for development 
and production at the Stepnoy Leopard Fields. This 
distinction ensures proper allocation of the 
purchase price and reflects the underlying value 
attributed to exploration and valuation assets 
within the transaction. 

In addition, the fair value of the minority interest 
representing 20% ownership retained by the 
previous partners of Positiv Invest LLP was 
recognized at the proportion of the net assets of 
Positiv Invest at the transaction date. Management 
believes that this recognition aligns with the 
principle of reflecting the true economic value of 
the minority interest within the financial 
statements. 

For more detailed information regarding 
exploration and evaluation assets, please see 
Note 6 in the financial statements. 

4.  Summary of material accounting policies

EExxpplloorraattiioonn  eexxppeennddiittuurree  

Costs directly associated with the purchase of 
Positiv Invest LLP and the appraisal of the wells are 
capitalised within exploration and evaluation 
assets until the reserve appraisal phase is 
complete and the commercial viability of field 
development have been proved.  

These costs include employee remuneration, 
materials, fuel used, rig costs, payments made to 
contractors, and asset retirement obligation fees. 

If hydrocarbons are found and, subject to further 
appraisal activity (e.g., the drilling of additional 
wells), it is probable that they can be commercially 
developed, the costs continue to be carried as an 
asset while sufficient/continued progress is made 
in assessing the commerciality of the 
hydrocarbons. 

All such carried costs are subject to technical, 
commercial and management review at least once 
a year to confirm the continued intent to develop 
or otherwise extract value from the discovery, 
which is subject to estimation uncertainties. When 
this is no longer the case, the costs are written off. 

Subsoil use rights acquisition costs are initially 
capitalised in exploration and evaluation assets. 
Subsoil use rights acquisition costs are reviewed at 
each reporting date to confirm that there is no 
indication that the carrying amount exceeds the 
recoverable amount. This review includes 
confirming that exploration drilling is still under 
way or firmly planned, or that it has been 
determined, or work is under way to determine 
that the discovery is economically viable based on 

a range of technical and commercial 
considerations and sufficient progress is being 
made on establishing development plans and 
timing. If no future activity is planned or the 
subsoil use rights have been relinquished or have 
expired, the carrying value of the subsoil use rights 
acquisition costs is written off through profit or 
loss.  

The Group holds the rights to the Stepnoy Leopard 
Fields located in the West Kazakhstan region 
where the exploration periods will expire 
respectively in 2044. The Group remains 
committed to developing its exploration assets 
and, therefore, continues to carry the capitalised 
costs on its balance sheet. For more detailed 
information in relation to the subsoil use rights 
terms, please see Note 1.

Management used judgment when considering 
the purchase of Positiv Invest LLP as an asset 
acquisition rather than a business acquisition. 
Management applied the concentration test, 
introduced within IFRS 3, which offers a simplifying 
procedure to ascertain if an acquisition is of a 
business or merely assets. If a substantial majority 
of the fair value of the gross assets acquired is 
concentrated in a single identifiable asset or group 
of similar assets, then the set isn't deemed a 
business. Taking into account that the most 
significant assets of the Positiv Invest LLP are the 
licenses to the Stepnoy Leopard’s fields, which are 
geographically co-located, and most of the balance 
sheet items are attributable to these fields, the

Oil and gas properties 

Expenditure on the construction, installation or 
completion of infrastructure facilities such as 
treatment facilities, pipelines and the drilling of 
development wells, is capitalised within property, 
plant and equipment as oil and gas properties. The 
initial cost of an asset comprises of its purchase 
price or construction cost, any costs directly 
attributable to bringing the asset into operation 
and the initial estimate of decommissioning 
obligations, if any. 

The purchase price or construction cost is the 
aggregate amount paid and the fair value of any 
other consideration given to acquire the asset. 
When a development project moves into the 
production stage, the capitalisation of certain 
construction/development costs ceases, and costs 
are either regarded as part of the cost of inventory 
or expensed, except for costs which qualify for 
capitalisation relating to oil and gas property asset 
additions, improvements or new developments. 

All capitalised costs of oil and gas properties are 
depleted using the unit-of-production method 
based on estimated proved developed reserves of 
the field, except the Group depreciates its oil 
pipeline and oil loading terminal on a straight-line 
basis over the life of the relevant subsoil use rights. 
In the case of assets that have a useful life shorter 
than the lifetime of the field the straight-line 
method is applied. 

Other properties 

All other property, plant and equipment are stated 
at historical cost less accumulated depreciation 
and impairment. Historical cost includes 
expenditures that are directly attributable to the 
acquisition of the items. Subsequent costs are 
included in the asset's carrying amount or 
recognised as a separate asset, as appropriate, 
only when it is probable that future economic 
benefits associated with the item will flow to the 
Group and the cost of the item can be measured 
reliably. All other repairs and maintenance are 
charged to the profit or loss during the year in 
which they are incurred. 

Depreciation is calculated on a straight-line basis 
over the estimated useful lives of the assets as 
follows: 

Buildings and constructions 
Vehicles 
Machinery and equipment 
Other 

Years 
7-15 
8 
3-13 
3-10 

Land is a non-depreciable asset and therefore is 
not subject to depreciation. It is the company’s 
policy to maintain the original cost of land on the 
balance sheet. However, the land’s value may be 
reviewed periodically to determine if there is any 
impairment in value.  

For more detailed information in relation to 
property plant and equipment, please refer to 
Note 5.

Oil and gas reserves are a material factor in the 
Group’s computation of depreciation, depletion 
and amortisation (the “DD&A”). Management 
used significant accounting judgement in selecting 
proved developed hydrocarbon reserves for 
calculating the unit-of-production depletion rate, 
as it reflects the expected pattern of consumption 
of future economic benefits by the Group. 

SSiiggnniiffiiccaanntt  eessttiimmaatteess  aanndd  aassssuummppttiioonnss::  ooiill  
aanndd  ggaass  rreesseerrvveess  

The Group uses internal estimates to assess the oil 
and gas reserves of its fields. The reserves 
estimates are made in accordance with the 
methodology of the Society of Petroleum 
Engineers (the “SPE”) and are confirmed or 
audited by independent reserve engineers. All 
reserve estimates involve some degree of 
uncertainty, which depends mainly on the amount 
of reliable geological and engineering data 
available at the time of the estimate and the 
interpretation of this data, as well as long-term 
hydrocarbon pricing, which may affect 
classification of reserves. 

The relative degree of uncertainty can be 
conveyed by placing reserves into one of two 
principal classifications, either proved or unproved. 
Proved reserves are more certain to be recovered 
than unproved reserves and may be further sub 
classified as developed and undeveloped to 
denote progressively increasing uncertainty in their 
recoverability.  

Reserves estimates are reviewed and revised 
annually. Revisions occur due to the evaluation or 
re-evaluation of already available geological, 
reservoir or production data; availability of new 
data; or changes to underlying price assumptions. 
Reserve estimates may also be revised due to 
improved recovery projects, changes in production 
capacity or changes in development strategy.  

Management’s estimates of the Chinarevskoye 2P 
(Proved plus Probable) volume as at 31 December 
2023 was 23.2 mmboe requiring 16 capital 
interventions (2022: 28.3 mmboe requiring 17 
interventions). The reduction was primarily due to 
2022 production of 3.7 mmboe and downwards 
revision of probable undeveloped reserves by 1.2 
mmboe mainly due to reduced expectations for 
Biyski gas-condensate resulting from increased 
water ingress. 

Downward revision of the proved developed 
reserves estimates by 5% would lead to additional 
DD&A expense of $2,022 thousand in 2023.  

Estimates of economically recoverable oil and gas 
reserves and related future net cash flows also 
impact the impairment assessment of the Group 
(see Impairment related significant judgements, 
estimates and assumptions for further details).  

Details on carrying values of oil and gas properties 
and related depreciation, depletion and 
amortization are shown in Note 5. 

In addition, provisions for decommissioning may 
require revision — where changes to reserves 
estimates affect expectations about when such 
activities will occur and the associated cost of 
these activities (see Decommissioning related

At the end of each reporting period the Group 
assesses whether events or changes in 
circumstances indicate that the carrying amount of 
an asset or CGU may not be recoverable; for 
example, changes in the Group’s business plans, 
significant decreases in the market commodity 
prices, low plant utilisation, evidence of physical 
damage or, for oil and gas assets, significant 
downward revisions of estimated reserves or 
increases in estimated future development 
expenditure or decommissioning costs. If any such 
indication of impairment exists, the Group makes 
an estimate of the asset’s recoverable amount. 

Individual assets are grouped into a CGU for 
impairment assessment purposes at the lowest 

level at which there are identifiable cash flows that 
are largely independent of the cash flows of other 
groups of assets. A CGU’s recoverable amount is 
the higher of its fair value less costs of disposal and 
its value in use. Where the carrying amount of a 
CGU exceeds its recoverable amount, the CGU is 
considered impaired, and an impairment loss is 
recognised for the excess of carrying amount over 
recoverable amount.  

The business cash flow internal model, which is 
approved on an annual basis by senior 
management, is the primary source of information 
for the determination of the recoverable amount. 
It contains forecasts for oil and gas production, 
sales volumes for various types of products, 

revenues, costs and capital expenditure. As an 
initial step in the preparation of this model, various 
assumptions are set by senior management. These 
assumptions take account of commodity prices, 
global supply-demand equilibrium for oil and 
natural gas, other macroeconomic factors and 
historical trends and variability. In assessing the 
recoverable amount, the estimated future cash 
flows are adjusted for the risks specific to the asset 
group and are discounted to their present value 
using a discount rate.

Judgement is required to identify cash-generating units for the purpose of 
testing the assets for impairment. Management has determined a single cash-
generating unit within the Group’s non-current assets consisting of all Group’s 
assets related to its Chinarevskoye field and facilities. This is mainly based on 
the fact that hydrocarbons extracted from the Chinarevskoye field are 
processed and passed through a combination of various facilities. 

SSiiggnniiffiiccaanntt  eessttiimmaatteess  aanndd  aassssuummppttiioonnss::  iimmppaaiirrmmeenntt  ooff  pprrooppeerrttyy,,  
ppllaanntt  aanndd  eeqquuiippmmeenntt,,  eexxpplloorraattiioonn  aanndd  eevvaalluuaattiioonn  aasssseettss    

Determination as to whether, and by how much, the CGU is impaired involves 
management’s best estimates on highly uncertain matters such as future 
commodity prices, operating expenses and capital expenditures estimates, 
discount rate, fiscal regimes, proved and probable reserves, contingent 
resources and respective future production profiles.  

Based on the management assessment the recoverable amount was 
determined by the fair value less costs of disposal (FVLCD) of the CGU, which 
was higher than its value-in-use. FVLCD was based on the discounted cash flow 
model as no recent third-party transactions existed on which a reliable market-
based fair value could be established.  

The discounted cash flow model takes into consideration cash flows, which are 
expected to arise until 2032, i.e. during the licence term of the Chinarevskoye 
field, and is considered a level 3 valuation under the fair value hierarchy, 
because the valuation methods is represented by discounted cashflow model 
using mix of observable and unobservable inputs. The period exceeding five 
years is believed to be appropriate based on the proved and probable reserves 
audited by independent engineers. The model also takes into account risked-
value cash flows from contingent resources on the basis a market participant 
would place value on these resources. 

The key assumptions used in the Group’s discounted cash flow model reflecting 
past experience and taking into account external factors are subject to periodic 
review. These assumptions are: 

•  Oil prices (in real terms): US$75/bbl for 2024 and US$70/bbl throughout 

2025-2032 (2022: US$75/bbl for 2023, US$73/bbl for 2024 and US$65/bbl 
throughout 2025-2032); 

•  Proved and probable hydrocarbon reserves based on management 

estimates, updated from reserves confirmed by independent reserve 
engineers at 31 December 2022; 

•  Production profiles based on Group’s internal estimates prepared by 

management; 

•  All cash flows are projected on the basis of stable prices, i.e. inflation/growth 

rates are ignored; 

•  Cost profiles for the development of the fields and subsequent operating 
costs consistent with reserves estimates and production profiles; and 
•  Gas treatment unit (GTU) spare capacity utilization – risk-weighted option 

value from processing under the contract with Ural Oil & Gas LLP;  
•  Post-tax discount rate of 10,3%, estimated to be equivalent to pre-tax 

discount rate of 14.0% (2022: 11.6% and 16.5%, respectively). 

The impairment testing carried out by the Group as of 31 December 2023 and 
2022 has resulted in the recoverable amount approximating the carrying 
amount of the Group’s property, plant and equipment as of 31 December 2023 
and 2022, respectively. Hence no impairment charge or reversal was recognised 
during these years. 

More detailed information on carrying values of oil and gas properties and 
related depreciation, depletion, amortisation and impairment are shown in 
Note 5. 

The following table summarizes sensitivity of the recoverable amount and 
respective potential impairment charges that would result from changes in the 
key assumptions:

On the other hand, certain positive development like successful mitigation of 
reservoir risks in the future and respective changes in the drilling plans and 
results, with the relevant increase in 2P reserves, or increase in utilisation of the 
Group’s processing facilities, could have the effect of reversing the impairment. 
Any reversal would be limited so that the carrying amount of the CGU does not 
exceed the lower of its recoverable amount, or the carrying amount that would 
have been determined, net of depreciation, had no impairment charge been 
recognised for the CGU in prior years.

Leases  

The Group applies a single recognition and 
measurement approach for all leases, except for 
short-term leases and leases of low-value assets. 
The Group recognises lease liabilities to make lease 
payments and right-of-use assets representing the 
right to use the underlying assets. 

Right-of-use assets 
The Group recognises right-of-use assets at the 
commencement date of the lease (i.e., the date the 
underlying asset is available for use). Right-of-use 
assets are measured at cost, less any accumulated 
depreciation and impairment losses, and adjusted 
for any remeasurement of lease liabilities. The cost 
of right-of-use assets includes the amount of lease 
liabilities recognised, initial direct costs incurred, 
and lease payments made at or before the 
commencement date less any lease incentives 
received. Unless the Group is reasonably certain to 
obtain ownership of the leased asset at the end of 
the lease term, the recognised right-of-use assets 
are depreciated on a straight-line basis over the 
shorter of its estimated useful life and the lease 
term. Right-of-use assets are subject to impairment. 

Lease liabilities 
At the commencement date of the lease, the Group 
recognises lease liabilities measured at the present 
value of lease payments to be made over the lease 
term. The lease payments include fixed payments 
(including in substance fixed payments) less any 
lease incentives receivable, variable lease payments 
that depend on an index or a rate, and amounts 

BBuussiinneessss  ccoommbbiinnaattiioonnss  aanndd  ggooooddwwiillll  

expected to be paid under residual value 
guarantees. The lease payments also include the 
exercise price of a purchase option reasonably 
certain to be exercised by the Group and payments 
of penalties for terminating a lease, if the lease term 
reflects the Group exercising the option to 
terminate.  

Variable lease payments that do not depend on an 
index or a rate are recognised as expense in the 
period on which the event or condition that triggers 
the payment occurs. 

In calculating the present value of lease payments, 
the Group uses the incremental borrowing rate at 
the lease commencement date if the interest rate 
implicit in the lease is not readily determinable. 
After the commencement date, the amount of lease 
liabilities is increased to reflect the accretion of 
interest and reduced for the lease payments made. 
In addition, the carrying amount of lease liabilities is 
remeasured if there is a modification, a change in 
the lease term, a change in the in-substance fixed 
lease payments or a change in the assessment to 
purchase the underlying asset. 

Separation of lease and non-lease 
components 
When contracts for a lease (such as like lease of 
drilling rigs and rail-tank cars) include various 
additional services like personnel cost, 
maintenance, drilling related activities, and other 
items, the Group splits such non-lease components 
and recognises them separately. Where the 
additional services are not separately priced, the 

consideration paid is allocated based on the relative 
stand-alone prices of the lease and non-lease 
components. 

Distinguishing fixed and variable lease 
payment elements 
Certain lease contracts include fixed rates for when 
the asset is in operation, and various alternative 
rates (like “cold-stack rates” for leases of drilling 
rigs) for periods where the asset is engaged in 
specified activities or idle, but still under contract. In 
general, variability in lease payments under these 
contracts has its basis in different use and activity 
levels, and the variable elements have been 
determined to relate to non-lease components only. 
Consequently, the lease components of these 
contractual payments are considered fixed for the 
purposes of IFRS 16. 

Short-term leases and leases of low-value 
assets 
The Group applies the short-term lease recognition 
exemption to its short-term leases of machinery and 
equipment (i.e., those leases that have a lease term 
of 12 months or less from the commencement date 
and do not contain a purchase option). It also 
applies the lease of low-value assets recognition 
exemption to leases of office equipment that are 
considered of low value (i.e., below US$ 5,000). 
Lease payments on short-term leases and leases of 
low-value assets are recognised as expense on a 
straight-line basis over the lease term.

Business combinations are accounted for using the 
acquisition method. The cost of an acquisition is 
measured as the aggregate of the consideration 
transferred, measured at acquisition date fair value 
and the amount of any non-controlling interest 
(“NCI”) in the acquiree. For each business 
combination, the Group elects whether to measure 
NCI in the acquiree at fair value or at the 
proportionate share of the acquiree’s identifiable 
net assets. Acquisition related costs are expensed as 
incurred and included in administrative expenses. 

When the Group acquires a business, it assesses the 
assets and liabilities assumed for appropriate 
classification and designation in accordance with the 
contractual terms, economic circumstances and 
pertinent conditions as at the acquisition date. This 
includes the separation of embedded derivatives in 
host contracts by the acquiree. Those acquired 
petroleum reserves and resources that can be 

reliably measured are recognised separately in the 
assessment of fair values on acquisition. Other 
potential reserves, resources and rights are included 
in goodwill.  

Goodwill is initially measured at cost, being the 
excess of the aggregate of the consideration 
transferred and the amount recognised for NCI over 
the fair value of the identifiable net assets acquired 
and liabilities assumed. If the fair value of the 
identifiable net assets acquired is in excess of the 
aggregate consideration transferred (bargain 
purchase), before recognising a gain, the Group 
reassesses whether it has correctly identified all of 
the assets acquired and all of the liabilities assumed 
and reviews the procedures used to measure the 
amounts to be recognised at the acquisition date. If 
the reassessment still results in an excess of the fair 
value of net assets acquired over the aggregate 
consideration transferred, then the gain is 

recognised in the statement of profit or loss and 
other comprehensive income. 

After initial recognition, goodwill is measured at cost 
less any accumulated impairment losses. For the 
purpose of impairment testing, goodwill acquired in 
a business combination is, from the acquisition date, 
allocated to each of the Group’s CGUs that are 
expected to benefit from the combination, 
irrespective of whether other assets or liabilities of 
the acquiree are assigned to those units.  

Where goodwill forms part of a Cash Generating 
Unit (“CGU”) and part of the operation in that unit is 
disposed of, the goodwill associated with the 
disposed operation is included in the carrying 
amount of the operation when determining the gain 
or loss on disposal. Goodwill disposed of in these 
circumstances is measured based on the relative 
values of the disposed operation and the portion of 
the CGU retained.

TTaaxxaattiioonn  

Uncertainties exist with respect to the 
interpretation of complex tax regulations, changes 
in tax laws, and the amount and timing of future 
taxable income. Given the wide range of 
international business relationships and the long-
term nature and complexity of existing contractual 
agreements, differences arising between the actual 
results and the assumptions made, or future 
changes to such assumptions, could necessitate 
future adjustments to tax bases of income and 
expense already recorded. The Group establishes 
provisions, based on reasonable estimates, for 
possible consequences of audits by the tax 
authorities of the respective counties in which it 
operates. The amount of such provisions is based on 
various factors, such as experience of previous tax 
audits and differing interpretations of tax 
regulations by the Group and the responsible tax 
authority. Such differences in interpretation may 
arise for a wide variety of issues depending on the 
conditions prevailing in the respective domicile of 
the Group companies. 

Current income tax 

Current income tax assets and liabilities are 
measured at the amount expected to be recovered 
from or paid to the taxation authorities. The tax 
rates and tax laws used to compute the amount are 
those that are enacted or substantively enacted at 
the reporting date in the countries where the Group 
operates and generates taxable income. The tax 
rates and tax laws used to compute the amount are 
those that apply to the relevant taxable income. 

Current income tax relating to items recognised 
directly in equity is recognised in equity and not in 
the statement of profit or loss. Management 
periodically evaluates positions taken in the tax 

FFoorreeiiggnn  ccuurrrreennccyy  ttrraannssllaattiioonn  

returns with respect to situations in which 
applicable tax regulations are subject to 
interpretation and establishes provisions where 
appropriate. 

Deferred income tax 

Deferred tax assets and liabilities are calculated in 
respect of temporary differences using the liability 
method. Deferred income taxes are provided for all 
temporary differences arising between the tax 
bases of assets and liabilities and their carrying 
values for financial reporting purposes, except 
where the deferred income tax arises from the 
initial recognition of goodwill or of an asset or 
liability in a transaction that is not a business 
combination and, at the time of the transaction, 
affects neither the accounting profit nor taxable 
profit or loss.  

A deferred tax asset is recorded only to the extent 
that it is probable that taxable profit will be 
available against which the deductible temporary 
differences can be utilised. Deferred tax assets and 
liabilities are measured at tax rates that are 
expected to apply to the period when the asset is 
realised or the liability is settled, based on tax rates 
that have been enacted or substantively enacted at 
the reporting date. 

Deferred income tax is provided on temporary 
differences arising on investments in subsidiaries, 
except where the timing of the reversal of the 
temporary difference can be controlled and it is 
probable that the temporary difference will not 
reverse in the foreseeable future. 

Deferred tax assets and deferred tax liabilities are 
offset if a legally enforceable right exists to set off 
current tax assets against current tax liabilities and 

the deferred taxes relate to the same taxable entity 
and the same taxation authority. 

For more detailed information in current and 
deferred income tax disclosure as at 31 December 
2023 and 2022, please see Notes 27 and 30. 

Significant accounting judgment: taxation 

Kazakhstan’s tax legislation and regulations are 
subject to ongoing changes and varying 
interpretations. Instances of inconsistent opinions 
between local, regional and national tax authorities 
are not unusual. Because of the uncertainties 
associated with Kazakhstan’s tax system, the 
ultimate amount of taxes, penalties and interest, if 
any, may be in excess of the amount expensed to 
date and accrued at 31 December 2023.  

The Group is subject to routine tax audits and also a 
process whereby tax computations are discussed 
and agreed with the tax authorities. Whilst the 
ultimate outcome of such tax audits and discussions 
cannot be determined with certainty, and hence 
requires management judgement, the level of 
provisions are estimated by management as 
required for taxes for which it is considered 
probable will be payable, based on professional 
advice and consideration of the nature of current 
discussions with the tax authority.  

As at 31 December 2023 management believes that 
its interpretation of the relevant legislation is 
appropriate and that it is probable that the Group’s 
tax position will be sustained. To the extent that 
actual outcomes differ from management’s 
estimates, income tax charges or credits, and 
changes in current and deferred tax assets or 
liabilities, may arise in future periods. For more 
information, see Notes 27 and 30. 

The functional currency is the currency of the 
primary economic environment in which an entity 
operates and is normally the currency in which the 
entity primarily generates and expends cash.  

Transactions in foreign currencies are initially 
recorded by the Group’s subsidiaries at their 
respective functional currency spot rates at the date 
the transaction first qualifies for recognition. 

The functional currency of the Company is the 
United States dollar (the “US dollar” or “US$”). The 
functional currencies of the Group’s subsidiaries are 
as follows: 

Monetary assets and liabilities denominated in

exchange rates at the date when the fair value is 
determined. 

In the consolidated financial statements, the assets 
and liabilities of non-US dollar functional currency 
subsidiaries are translated into US dollars at the spot 
exchange rate on the balance sheet date. The 
results and cash flows of non-US dollar functional 
currency subsidiaries are translated into US dollars 
using average rates of exchange, and resulting 
exchange differences are accumulated foreign

The Group capitalises borrowing costs on qualifying 
assets. Assets qualifying for borrowing costs 
capitalisation include all assets under construction 
that are not being depreciated, depleted, or 
amortised, provided that work is in progress at that 
time. Qualifying assets mostly include wells and 
other operations field infrastructure under 
construction. Capitalised borrowing costs are 
calculated by applying the capitalisation rate to the 
expenditures on qualifying assets. The capitalisation 
rate is the weighted average of the borrowing costs 
applicable to the Group’s borrowings that are 
outstanding during the period. All other borrowing 
costs are recognised in the profit or loss in the 
period in which they are incurred. 

For more detailed information in relation to 
capitalisation of borrowing costs, please refer to 
Note 5. 

Advances paid for capital investments/acquisition of 
non-current assets are qualified as advances for 
non-current assets regardless of the period of 
supplies of relevant assets or the supply of work or 
services to close advances. Advances paid for the 
purchase of non-current assets are recognised by 
the Group as non-current assets and are not 
discounted. 

For more detailed information in relation to 
advances for non-current assets, please refer to 
Note 7.

Inventories are stated at the lower of cost or net

and liquefied petroleum gas (“LPG”) is determined 
on the weighted-average method based on the 
production cost including the relevant expenses on 
depreciation, depletion and impairment and 

overhead costs based on production volume. Net 
realisable value is the estimated selling price in the 
ordinary course of business, less selling expenses.

The Group makes accruals for liabilities related to 
the underperformance and/or adjustments of work 
programs under subsoil use agreements (SUA) on a 
regular basis. When evaluating the adequacy of an 
accrual, management bases its estimates on the 
latest work program included in the SUA, and 
relevant signed supplements and potential future 
changes in payment terms (including the currency in 
which these liabilities are to be settled).  

Future changes in the work programs may require 
adjustments to the accrual recorded in the 
consolidated financial statements. 

PPrroovviissiioonnss  aanndd  ccoonnttiinnggeenncciieess

Provisions are recognised when the Group has a 
present obligation (legal or constructive) as a result 
of a past event, it is probable that an outflow of 
resources embodying economic benefits will be 
required to settle the obligation and a reliable 
estimate of the amount of the obligation can be 
made. Provisions are reviewed by the Group at each 
reporting date and adjusted to reflect the current 
best estimate. If it is no longer probable that an 
outflow of resources embodying economic benefits 
will be required to settle the obligation, the 
provision is reversed. 

The Group classifies as contingent liabilities those 
possible obligations that arise from past events and 
whose existence will be confirmed only by the 
occurrence or non-occurrence of one or more 
uncertain future events not wholly within the 

control of the enterprise and the present obligations 
that arise from past events but are not recognised 
because it is not probable that an outflow of 
resources embodying economic benefits will be 
required to settle the obligation or the amount of 
the obligation cannot be measured with sufficient 
reliability.  

The Group does not recognise contingent liabilities 
but discloses contingent liabilities in Note 30, unless 
the possibility of an outflow of resources embodying 
economic benefits is remote. 

Significant accounting judgment: provisions and 
contingencies 

Provisions and liabilities are recognized in the period 
when it becomes probable that there will be a 
future outflow of funds resulting from past 

operations or events and the amount of cash 
outflow can be reliably estimated. The timing of 
recognition and quantification of the liability require 
the application of judgment to existing facts and 
circumstances, which can be subject to change. The 
carrying amounts of provisions and liabilities are 
reviewed regularly and adjusted to take account of 
changing facts and circumstances.  

Significant management judgment is required to 
evaluate any claims and actions to determine 
whether a provision relating to a specific litigation 
should be recognized or revised, or a contingent 
liability is required to be disclosed, since the 
outcome of litigation is difficult to predict.  

For more detail on provisions and contingencies, 
please refer to Note 30.

Provision for decommissioning is recognised in full, 
when the Group has an obligation to dismantle and 
remove a facility or an item of plant and to restore 
the site on which it is located, and when a 
reasonable estimate of that provision can be made.  

The Group estimates future dismantlement and site 
restoration costs for oil and gas properties with 
reference to the estimates provided from either 
internal or external engineers after taking into 
consideration the anticipated method of 
dismantlement and the extent of site restoration 
required in accordance with current legislation and 
industry practice. The amount of the provision is the 
present value of the estimated expenditures 
expected to be required to settle the obligation at 
current year prices discounted at pre-tax rate that 
reflects current market assessment of the time 
value of money and the risks specific to liability.  

The unwinding of the discount related to the 
obligation is recorded in finance costs. A 
corresponding amount equivalent to the provision is 
also recognised as part of the cost of the related oil 
and gas properties. This asset is subsequently 
depreciated as part of the capital costs of the oil and 
gas properties on a unit-of-production basis.  

The Group reviews site restoration provisions at 
each financial reporting date and adjusts them to 
reflect current best estimates in accordance with 
IFRIC 1 Changes in Existing Decommissioning, 
Restoration and Similar Liabilities.  

Changes in the measurement of an existing 
decommissioning liability that result from changes 
in the estimated timing or amount of the outflow of 
resources embodying economic benefits required to 
settle the obligation, or changes to the discount 
rate: 

•  are added to, or deducted from, the cost of the 
related asset in the current period. If deducted 
from the cost of the asset the amount deducted 
shall not exceed its carrying amount. If a 
decrease in the provision exceeds the carrying 
amount of the asset, the excess is recognised 
immediately in the profit or loss; and 

•  if the adjustment results in an addition to the 
cost of an asset, the Group considers whether 
this is an indication that the new carrying amount 
of the asset may not be fully recoverable. If it is 
such an indication, the Group tests the asset for 
impairment by estimating its recoverable 
amount, and accounts for any impairment loss in 
accordance with IAS 36. 

Movements in the abandonment and site 
restoration provision are disclosed in Note 15.

Significant estimates and assumptions: provisions 
and contingencies 

The Group holds provision for the future 
decommissioning of oil and gas properties and site 
restoration. The estimation of the future 
dismantlement and site restoration costs involves 
use of significant estimates and assumptions by 
management, specifically for determining the timing 
of the future cash outflows and discount rate.  

Management made its estimates based on the 
assumption that cash flow will take place at the 
expected end of the subsoil use rights. Therefore, 

most decommissioning events are many years in the 
future and the precise date of wells abandonment 
and site restoration may change with the relative 
impact on the cash outflows. 

Management of the Group believes that the long-
term US Treasury real yield curve rates adjusted for 
country risk premium of Kazakhstan provides the 
best estimates of applicable real discount rate.  

Any changes in the expected future costs are 
reflected in both the provision and the asset. 
Moreover, actual decommissioning costs can differ 
from estimates because of constantly changing 

decommissioning technologies as well as changes in 
environmental laws and regulations and public 
expectations.  

As a result, there could be significant adjustments to 
the provisions established which would affect future 
financial results. For example, 10% increase in the 
cost of decommissioning may lead to additional 
US$2,002 liability. 

For more details on abandonment and site 
restoration provision please refer to Note 15.

Initial recognition and measurement  

Financial assets are classified, at initial recognition, 
as subsequently measured at amortised cost and 
fair value through profit or loss. The Group 
determines the classification of its financial assets at 
initial recognition. 

The classification of financial assets at initial 
recognition depends on the financial asset’s 
contractual cash flow characteristics and the 
Group’s business model for managing them. With 
the exception of trade receivables that do not 
contain a significant financing component or for 
which the Group has applied the practical 
expedient, the Group initially measures a financial 
asset at its fair value plus, in the case of a financial 
asset not at fair value through profit or loss, 
transaction costs. Trade receivables that do not 
contain a significant financing component or for 
which the Group has applied the practical expedient 
are measured at the transaction price determined 
under IFRS 15.   

In order for a financial asset to be classified and 
measured at amortised cost or fair value through 
OCI, it needs to give rise to cash flows that are 
‘solely payments of principal and interest (SPPI)’ on 
the principal amount outstanding. This assessment 
is referred to as the SPPI test and is performed at an 
instrument level. 

The Group’s business model for managing financial 
assets refers to how it manages its financial assets in 
order to generate cash flows. The business model 
determines whether cash flows will result from 
collecting contractual cash flows, selling the financial 
assets, or both. 

Purchases or sales of financial assets that require 
delivery of assets within a time frame established by 
regulation or convention in the market place 
(regular way trades) are recognised on the trade 
date, i.e., the date that the Group commits to 
purchase or sell the asset. 

Subsequent measurement 

For purposes of subsequent measurement, financial 
assets are classified in four categories: 
•  Financial assets at amortised cost (debt 

instruments); 

•  Financial assets at fair value through OCI with 
recycling of cumulative gains and losses (debt 
instruments); 

•  Financial assets designated at fair value through 
OCI with no recycling of cumulative gains and 
losses upon derecognition; 

•  Financial assets at fair value through profit or 

loss. 

Financial assets at amortised cost (debt 
instruments) 

This category is the most relevant to the Group. The 
Group measures financial assets at amortised cost if 
both of the following conditions are met: 
•  The financial asset is held within a business 

model with the objective to hold financial assets 
in order to collect contractual cash flows, and 
•  The contractual terms of the financial asset give 
rise on specified dates to cash flows that are 
solely payments of principal and interest on the 
principal amount outstanding. 

Financial assets at amortised cost are subsequently 
measured using the effective interest (EIR) method 
and are subject to impairment. Gains and losses are 
recognised in profit or loss when the asset is 
derecognised, modified or impaired. 

The Group’s financial assets at amortised cost 
include cash, long-term and short-term deposits, 
trade and other receivables.  

Derecognition 

•  The rights to receive cash flows from the asset 

have expired; or 

•  The Group has transferred its rights to receive 
cash flows from the asset or has assumed an 
obligation to pay the received cash flows in full 
without material delay to a third party under a 
‘pass-through’ arrangement; and either (a) the 
Group has transferred substantially all the risks 
and rewards of the asset, or (b) the Group has 
neither transferred nor retained substantially all 
the risks and rewards of the asset, but has 
transferred control of the asset. 

When the Group has transferred its rights to receive 
cash flows from an asset or has entered into a pass-
through arrangement, it evaluates if, and to what 
extent, it has retained the risks and rewards of 
ownership. When it has neither transferred nor 
retained substantially all of the risks and rewards of 
the asset, nor transferred control of the asset, the 
Group continues to recognise the transferred asset 
to the extent of its continuing involvement. In that 
case, the Group also recognises an associated 
liability. The transferred asset and the associated 
liability are measured on a basis that reflects the 
rights and obligations that the Group has retained. 

Impairment of financial assets 

The Group recognises an allowance for expected 
credit losses (ECLs) for all debt instruments not held 
at fair value through profit or loss. ECLs are based on 
the difference between the contractual cash flows 
due in accordance with the contract and all the cash 
flows that the Group expects to receive, discounted 
at an approximation of the original effective interest 
rate. The expected cash flows will include cash flows 
from the sale of collateral held or other credit 
enhancements that are integral to the contractual 
terms. 

A financial asset (or, where applicable, a part of a 
financial asset or part of a group of similar financial 
assets) is primarily derecognised (i.e., removed from 
the Group’s consolidated statement of financial 
position) when: 

For trade receivables and contract assets, the Group 
applies a simplified approach in calculating ECLs. 
Therefore, the Group does not track changes in 
credit risk, but instead recognises a loss allowance 
based on lifetime ECLs at each reporting date.

Initial recognition, measurement and 
derecognition 

•  Financial liabilities at amortised cost (loans and 

borrowings) 

Derecognition 

Financial liabilities are classified, at initial 
recognition, as financial liabilities at fair value 
through profit or loss, long-term borrowings, 
payables, or as derivatives designated as hedging 
instruments in an effective hedge, as appropriate.  

All financial liabilities are recognised initially at fair 
value and, in the case of long-term borrowings and 
payables, net of directly attributable transaction 
costs. 

The Group’s financial liabilities include trade and 
other payables, long-term borrowings, and 
derivative financial instruments. 

Subsequent measurement 

For purposes of subsequent measurement, financial 
liabilities are classified in two categories: 
•  Financial liabilities at fair value through profit or 

loss 

CCaasshh  aanndd  ccaasshh  eeqquuiivvaalleennttss      

Cash and cash equivalents in the statement of 
financial position comprise cash at banks and at 
hand and short-term deposits with an original 
maturity of three months or less at inception. 

Restricted cash and cash equivalent balances are 
those which meet the definition of cash and cash 
equivalents but are not available for use by the 
Group and therefore is not considered highly liquid 
– for example, cash set aside to cover 
decommissioning obligations or as required by the 
forbearance agreement. 

For the purpose of the consolidated statement of 
cash flows, cash and cash equivalents consist of 
cash and cash equivalents, as defined above, net of 
outstanding bank overdrafts. 

For more detailed information in relation to cash 
and cash equivalents as at 31 December 2023 and 
2022, please see Note 11. 

RReevveennuuee  rreeccooggnniittiioonn    

The Group sells crude oil, gas condensate and LPG 
under agreements priced by reference to Platt’s 
and/or Argus’ index quotations and adjusted for 
freight, insurance and quality differentials where 
applicable. The Group sells gas under agreements 
at fixed prices.  

FFiinnaanncciiaall  lliiaabbiilliittiieess  aatt  aammoorrttiisseedd  ccoosstt  ((llooaannss  
aanndd  bboorrrroowwiinnggss))  

This is the category most relevant to the Group. 
After initial recognition, interest-bearing borrowings 
are subsequently measured at amortised cost using 
the EIR method. Gains and losses are recognised in 
profit or loss when the liabilities are derecognised as 
well as through the EIR amortisation process. 

Amortised cost is calculated by taking into account 
any discount or premium on acquisition and fees or 
costs that are an integral part of the EIR. The EIR 
amortisation is included as finance costs in the 
statement of profit or loss. 

This category generally applies to interest-bearing 
borrowings. For more information, refer to Note 14. 

A financial liability is derecognised when the 
obligation under the liability is discharged or 
cancelled or expires. When an existing financial 
liability is replaced by another from the same lender 
on substantially different terms, or the terms of an 
existing liability are substantially modified, such an 
exchange or modification is treated as the 
derecognition of the original liability and the 
recognition of a new liability. The difference in the 
respective carrying amounts is recognised in the 
statement of profit or loss. 

Offsetting of financial instruments 

Financial assets and financial liabilities are offset and 
the net amount reported in the statement of 
financial position if, and only if, there is a currently 
enforceable legal right to offset the recognised 
amounts and there is an intention to settle on a net 
basis, or to realise the assets and settle the liabilities 
simultaneously. 

SShhaarree--bbaasseedd  ppaayymmeennttss  

The cost of equity-settled transactions is measured 
at fair value at the grant date. This fair value is 
expensed over the period until vesting with the 
recognition of a corresponding equity element, 
which is not remeasured subsequently until the 
settlement date.

Estimating fair value for share-based payment 
transactions requires determination of the most 
appropriate valuation model, which is dependent 
on the terms and conditions of the grant. This 
estimate also requires determination of the most 
appropriate inputs to the valuation model 
including the expected life of the share option, 
volatility and distribution yield and making 
assumptions about them. 

Revenue from contracts with customers is 
recognised when control of the goods is 
transferred to the customer. For sales of crude oil, 
gas condensate and LPG, this generally occurs 
when the product is physically transferred into a 
vessel, pipe, railcar, trucks or other delivery 
mechanism; for sales of gas, it is when the product 
is physically transferred into a pipe. The Group’s 
LPG are sales are mostly on advance payment 
basis, while payment terms for gas, oil and 
condensate are normally 15-45 days after delivery. 

The Group has generally concluded that it is the 
principal in its revenue arrangements, because it 
typically controls the goods before transferring 
them to the customer.   

TTrreeaassuurryy  sshhaarreess  

Own equity instruments that are reacquired 
(treasury shares) are recognised at cost and 
deducted from equity. No gain or loss is recognised 
in profit or loss on the purchase, sale, issue or 
cancellation of the Group’s own equity 
instruments. Any difference between the carrying 
amount and the consideration, if reissued, is 
recognised in the share premium. Voting rights 
related to treasury shares are nullified for the 
Group and no distributions are accepted in relation 
to them. Share options exercised during the 
reporting period can be satisfied with treasury 
shares.

treatment facilities, oil transportation and other related assets. The movement 
of oil and gas properties for the years ended 31 December 2023 and 2022 was 
as follows:  

The change in the discount rate used to determine the abandonment and site 
restoration provision (Note 15) in the year ended 31 December 2023 resulted 
in the decrease of the oil and gas properties by US$ 630 thousand

The category “Construction in progress” is represented by employee 
remuneration, materials and fuel used, rig costs, payments made to 
contractors, and asset retirement obligation fees directly associated with 
development of wells until the drilling of the well is complete and results have 
been evaluated. 

The depletion rate for oil and gas working assets was 21.52% and 21.73% in 
2023 and 2022, respectively. In 2023, the Group applied consistent approach in 
the estimation of oil & gas reserves adopting the same methodology with 
previous periods, however, the Group decided not to engage independent 
reserve auditors taking into account immaterial changes in the reserves 
estimates, which were in line with expectations.

169,381,600 

As part of the Restructuring, on 9 February 2023 the Company issued 
1,505,633,046 new shares in connection with the repayment of the remaining 
face value of the Existing Notes following the issue of the New Notes (see Note 
14 below), together with accrued but unpaid interest (the “Debt for Equity 
Swap”). Given the number of new shares issued, at the close of business on 9 
February 2023 the Company also performed a share consolidation, so as to 
achieve an appropriate share price following closing of the Restructuring (Note 
1). As a result, the number of ordinary shares in issue was reduced from 
1,693,816,004 (following the issue of the new shares) to 169,381,600 ordinary 
shares, on the basis of a 10:1 consolidation (the “Share Consolidation”). In 
order to give effect to the Share Consolidation, the Company initially reduced 
the nominal value of the ordinary shares (the “Sub-Division”) after the issue of 
the new shares, through sub-division of each ordinary share at a ratio of 1:10

resulting 15,244,344,036 Deferred Shares (in practice), which are not included 
in the table above, have no economic or voting rights in the capital of the

implementation of the Restructuring. The nominal value of the ordinary shares 
following the Share Consolidation was £0.01 each. Fractions of new ordinary

fractional entitlements were rounded down to the nearest whole ordinary 
share.

As part of the Restructuring 18,801,358  warrants were issued to the warrant 
trustee, which upon exercise in full, would result in the issue of new Ordinary 
Shares (the “Warrant Shares”) at their nominal value to the holders of the 
Existing Notes to Ordinary Shares from 88.89% to 90%, based upon the pro 
forma capitalisation of Nostrum immediately following closing of the 
Restructuring (but excluding entitlements under any new management 
incentive plan, long-term incentive plan or similar share scheme). 

The Warrants will be exercisable in full upon: 
•  a breach of the Company’s covenants or undertakings in relation to the 

SUNs or the Warrants; 

•  a change in, or breach of, certain agreed governance principles without 

approval from the Warrant Director (“Warrant Approval”); 

•  a change to the agreed composition of the Board that has not obtained 

Warrant Approval; or 

•  an exit event (as specifically defined in the instrument pursuant to which the 

Warrants will be constituted) but including, in principle, any delisting of 
Nostrum from the London Stock Exchange, a change of control, sale of all or 
substantially all assets, the commencement of any winding-up or similar 
process in relation to Nostrum, or merger of Nostrum (an “Exit”).

Senior Secured Notes (SSNs) 

Following the Restructuring of the 2025 and 2022 Notes, Nostrum Oil & Gas 
Finance BV, issued US$250,000,000 senior secured notes due 30 June 2026. 
The SSNs bear cash-pay interest at a rate of 5.0% per year, payable semi-
annually. Pursuant to the Lock-up Agreement, the Group has agreed that the 
5.0% cash interest will accrue from 1 January 2022 and such accrued amount 
was paid in cash after the issue of the SSNs. For more information, please refer 
to Note 1. 

Senior Unsecured Notes (SUNs) 

Following the Restructuring of the 2025 and 2022 Notes, Nostrum Oil & Gas 
Finance BV issued US$300,000,000 senior notes due 30 June 2026. The SUNs 
bear interest at a rate of 1.0% cash-pay and 13.0% payment-in-kind (PIK) per 
year, payable semi-annually. Pursuant to the Lock-up Agreement, the 
Company agreed that the 1.0% cash interest and 13.0% PIK interest would 
accrue from 1 January 2022. Accordingly, Nostrum Oil & Gas Finance issued a 
principal amount of US$45,078,172 additional SUNs representing the PIK 
interest which has been agreed to be payable with effect from 1 January 2022 
until 9 February 2022 upon the issue of the SUNs. For more information, please 
refer to Note 1 for Restructuring terms. 

2022 Notes 

On 25 July 2017, a newly incorporated entity, Nostrum Oil & Gas Finance B.V. 
(the "2022 Issuer") issued US$725,000 thousand notes with maturity on 25 July 
2022. The 2022 Notes bore interest at a rate of 8.00% per year, payable on 25 
January and 25 July of each year.  The 2022 Notes were jointly and severally 
guaranteed (the "2022 Guarantees") on a senior basis by Nostrum Oil & Gas 
PLC, Nostrum Oil & Gas Coöperatief U.A., Zhaikmunai LLP and Nostrum Oil & 
Gas B.V. (the "2022 Guarantors"). The 2022 Notes were the 2022 Issuer's and 
the 2022 Guarantors’ senior obligations and ranked equally with all of the 2022 
Issuer's and the 2022 Guarantors’ other senior indebtedness. The issue of the 
2022 Notes was used primarily to fund the refinancing of part of the Group’s 
Notes issued in 2012 and 2014.  

2025 Notes 

On 16 February 2018, Nostrum Oil & Gas Finance B.V. (the "2025 Issuer") 
issued US$400,000 thousand notes with maturity on 16 February 2025. The 
2025 Notes bore interest at a rate of 7.00% per year, payable on 16 August and 
16 February of each year. The 2025 Notes were jointly and severally 
guaranteed (the "2025 Guarantees") on a senior basis by Nostrum Oil & Gas 
PLC, Nostrum Oil & Gas Coöperatief U.A., Zhaikmunai LLP and Nostrum Oil & 
Gas B.V. (the "2025 Guarantors"). The 2025 Notes were the 2025 Issuer's and 
the 2025 Guarantors’ senior obligations and ranked equally with all of the 2025 

CChhaannggeess  iinn  lliiaabbiilliittiieess  aarriissiinngg  ffrroomm  ffiinnaanncciinngg  aaccttiivviittiieess

Issuer's and the 2025 Guarantors’ other senior indebtedness. The issue of the 
2025 Notes was used primarily to fund the refinancing of the remaining 
Group’s Notes issued in 2012 and 2014. 

Exchange of debt instruments 

Taking into account significant differences in the terms of the Existing Notes 
and the terms of SSNs and SUNs issued in exchange, the Group accounted for 
the exchange transaction in accordance with the requirements of IFRS 9 
Financial Instruments for a substantial modification, i.e. extinguishment of the 
Existing Notes and recognition of the New Notes at their fair value. 

Such fair values have been determined by discounting future cashflows at the 
relevant implied yields of the instruments on issue date (13.25% for SSNs and 
31.04% for SUNs). The resulting gains on initial recognition of SSNs and SUNs in 
the amount of $40.294 thousand and $134.132 thousand, respectively, were 
recorded in the income statements under separate line item. These 
adjustments will be amortised over the life of the instruments and reflected as 
part of finance costs in the income statement.  

Reclassification to current liabilities 

The Group has not made coupon payments due under the Existing Notes since 
July 2020, which was an event of default under the terms of the indentures 
governing 2022 Notes and 2025 Notes. Considering these facts and 
circumstances, starting from Q3 2020 the Group reclassified the carrying 
amounts of the 2022 Notes and 2025 Notes into current liabilities and since 
then and until the restructuring has been presenting them as the current 
portion of long-term borrowings in the statement of financial position.  

More detailed information for restructuring is disclosed in the Note 1. 

Covenants contained in the SSNs and SUNs 

The SSNs and SUNs contained consistent covenants that, among other things, 
sets following requirements, subject to certain exceptions and qualifications, 
the Issuer, the Guarantors, and certain other members of the Group: 
• Produce reports to holders, including quarterly and annual financial 
statements and certain other reports and documents upon request 
from bondholders; 

• Limitations on Indebtedness; 
• Limitations on restricted payments;  
• Limitations on restrictions on distributions from Group entities; 
• Limitations on sales of assets and equity interests in Group 

subsidiaries; 

• Limitations on affiliate transactions; 
• Limitation on line of business; 
• Listing of the bonds on international stock exchange; 
• Change of Control; 
• Limitation on Liens; 
• Limitation on issuances of guarantees of Indebtedness; 
• Payments for Consents; 
• Additional Amounts; 
• Compliance Certificates; Default Notices; 
• Registration with the National Bank of Kazakhstan; 
• Merger and Consolidation; 
• Cashflow Arrangements. 

In addition, the indentures imposed certain requirements as to future 
subsidiary guarantors, and certain customary information covenants and 
events of default.

best estimates and assessment of probabilities of cash outflows, such as 
penalties related to tax audit payments, environmental provision and other 
similar items. 

 Provision as at 31 December  

 22,147  

 Management's estimation is predicated on the expectation that cash flow will 
occur at the termination of the subsoil use rights, projected for 2032 for the 
Chinarevskoye field and 2044 for the Stepnoy Leopard fields. There are 
uncertainties in estimation of future costs as Kazakh laws and regulations 
concerning site restoration evolve. 

The real discount rate used to determine the abandonment and site 
restoration provision at 31 December 2023 was 4.52% (31 December 2022: 
4.87%). The change in the discount rate during the year ended 31 December 
2023 resulted in the increase of the abandonment and site restoration 
provision by US$629 thousand (31 December 2022: decrease US$9.206 
thousand). 

Additional provision is resulted from recognition liability for Stepnoy Leopard 
fields of 3 wells. 

16. Due to Government of Kazakhstan 

The amount due to Government of the Republic of Kazakhstan has been 
recorded to reflect the present value of a liability in relation to the 
expenditures made by the Government in the time period prior to signing the 
Contract that were related to exploration of the Contract territory and the 
construction of surface facilities in fields discovered therein and that are 
reimbursable by the Group to the Government during the production period. 
The total amount of liability due to Government as stipulated by the Contract is 
US$ 25,000 thousand. 

Repayment of this liability commenced in 2008 with the first payment of 
US$1,030 thousand in March 2008 and with further payments by equal 
quarterly instalments of US$258 thousand until 26 May 2031. The liability was 
discounted at 13%. 

The summary of the changes in the amounts due to Government of 
Kazakhstan during the years ended 31 December 2023 and 31 December 2022

25. Employees’ remuneration 

Employees (including senior executives and executive directors) of members of 
the Group may receive an award, which is a "nominal cost option" over a 
specified number of ordinary shares in the capital of the Company. The option 
has an exercise price of 1p per share (but the Company has the discretion to 
waive this prior to exercise). In addition, under the Rules of the LTIP the 
Company has discretion to settle awards other than by transfer of shares such 
as by way of cash settlement. Generally, the awards are classified as equity-
settled transactions. The share options are treated as equity-settled since there 
are no legal limitations expected on issue of shares for these upon vesting, the 
Group has a choice of settlement and the intention is to settle them in equity. 
However, in certain jurisdictions due to regulatory requirements the Company 
may not be able to settle the awards other than by transfer of cash, in which 
case the awards are classified as cash-settled transactions, and accounted for 
similar to SARs.

The Group’s Phantom Option Plan was adopted by the board of directors of 
the Company on 20 June 2014 to allow for the continuation of the option plan 
previously maintained by Nostrum Oil & Gas LP. The rights and obligations in 
relation to this option plan were transferred to Nostrum Oil & Gas PLC from 
Nostrum Oil & Gas LP following the reorganisation. 

Employees (including senior executives and executive directors) of members of 
the Group received remuneration in the form of equity-based payment 
transactions, whereby employees render services as consideration for share 
appreciation rights, which can only be settled in cash (“cash-settled 
transactions”).

In 2017 the Group started operating a Long-term incentive plan (“the LTIP”), 
that was approved by the shareholders of the Company on 26 June 2017 and 
adopted by the board of directors of the Company on 24 August 2017. The LTIP 
is a discretionary benefit offered by the Company for the benefit of selected 
employees. Its main purpose is to increase the interest of the employees in the 
Company's long-term business goals and performance through share 
ownership. The LTIP is an incentive for the employees' future performance and 
commitment to the goals of the Company. The remuneration committee of 
the board of the Company has the right to decide, in its sole discretion, 
whether or not further awards will be granted in the future and to which 
employees those awards will be granted.

Certain revisions to previous period tax assessments were made considering 
new information, which was not available at the time of preparation of 
respective financial information, and relevant interpretations by the 
management. During 2022 the tax authorities in Kazakhstan carried out a 
comprehensive tax audit of Zhaikmunai LLP for the financial years 2016-2021, 
as a result of which additional corporate income tax in a principal amount 
equivalent to US$12,500 thousand has been assessed for the periods covered.

The Group’s effective tax rate for the year ended 31 December 2023 is 
negative 0.5% (2022: 42.4%). The Group’s effective tax rate, excluding effect of 
movements in exchange rates, non-deductible interest expense on borrowings 
and other one-off items, for the year ended 31 December 2023 is 31.0% (2022: 
2.9%). 

As at 31 December 2023 the Group has tax losses of US$127,982 thousand 
(2022: US$122,111 thousand) that are available to offset against future taxable 
profits in the companies in which the losses arose within 9 years after 
generation and will expire in the period 2023-2029. On 21 May 2021, a Royal 
Decree was issued in the Netherlands, which dictates that the tax losses can 
now be carried forward indefinitely from 1 January 2022, subject to annual 
limit on carry back loss utilization. Deferred tax assets have not been 
recognised in respect of these losses as they may not be used to offset taxable 
profits elsewhere in the Group.

30. Contingent liabilities and commitments 

EEnnvviirroonnmmeennttaall  oobblliiggaattiioonnss  

TTaaxxaattiioonn    

Kazakhstan’s tax legislation and regulations are subject to ongoing changes and 
varying interpretations. Instances of inconsistent opinions between local, 
regional and national tax authorities are not unusual. The current regime of 
penalties and interest related to reported and discovered violations of 
Kazakhstan’s tax laws are severe and where the tax authorities disagree with 
the positions taken by the Group the financial outcomes could be material. 
Administrative fines are generally 80% of the taxes additionally assessed and 
interest penalty is assessed at the refinancing rate established by the National 
Bank of Kazakhstan multiplied by 1.25. As a result, penalties and interest can 
amount to multiples of any assessed taxes. Fiscal periods remain open to 
review by tax authorities for five calendar years preceding the year of review. 
Under certain circumstances reviews may cover longer periods. Because of the 
uncertainties associated with Kazakhstan’s tax system, the ultimate amount of 
taxes, penalties and interest, if any, may be in excess of the amount expensed 
to date and accrued at 31 December 2023. As at 31 December 2023 
management believes that its interpretation of the relevant legislation is 
appropriate and that it is probable that the Group’s tax position will be 
sustained. 

The Group may also be subject to loss contingencies relating to regional 
environmental claims that may arise from the past operations of the related 
fields in which it operates. Kazakhstan’s environmental legislation and 
regulations are subject to ongoing changes and varying interpretations. As 
Kazakh laws and regulations evolve concerning environmental assessments 
and site restoration, the Group may incur future costs, the amount of which is 
currently indeterminable due to such factors as the ultimate determination of 
responsible parties associated with these costs and the Government’s 
assessment of respective parties’ ability to pay for the costs related to 
environmental reclamation.  

However, depending on any unfavourable court decisions with respect to any 
claims or penalties assessed by the Kazakh regulatory agencies, it is possible 
that the Group’s future results of operations or cash flow could be materially 
affected in a particular period. 

CCaappiittaall  ccoommmmiittmmeennttss  

As at 31 December 2023, the Group had contractual capital commitments in 
the amount of US$ 16,039 thousand (31 December 2022: US$2,845 thousand), 
mainly in respect to the Group’s oil field development activities. 

PPeennddiinngg  ttaaxx  ddiissppuutteess    

SSoocciiaall  aanndd  eedduuccaattiioonn  ccoommmmiittmmeennttss  

As required by the Contract (after its amendment on 2 September 2019), the 
Group is obliged to: 
•  spend US$ 300 thousand per annum to finance social infrastructure; 
•  make an accrual of one percent per annum of the actual investments for the 

Chinarevskoye field for the purposes of educating Kazakh citizens. 

DDoommeessttiicc  ooiill  ssaalleess  

In accordance with Supplement # 7 to the Contract, Zhaikmunai LLP is required 
to deliver at least 15% of produced oil to the domestic market on a monthly 
basis for which prices are materially lower than export prices.  

In late 2023 the Kazakhstan tax authorities conducted a withholding tax audit 
of Zhaikmunai LLP for the financial year 2018, and in January 2024 issued a 
withholding tax assessment equivalent to US$6.8 million and related fines and 
penalties equivalent to US$5.1 million. According to Company’s best estimates, 
the application of similar arguments to the periods 2019-23 could result in 
additional amounts of taxes and penalties in the amount of circa US$3.0 
million. This excludes other items included within the assessment which the 
Company believes to be a remote risk. 

Whilst Zhaikmunai LLP successfully challenged the legality and enforceability of 
the 2018 withholding tax assessment in January 2024, the Kazakhstan tax 
authorities subsequently filed an appeal in April 2024 which will be heard in 
the appellate court. Following the decision of the appellate court, either party 
has the right to a final appeal to the Supreme Court of Kazakhstan.  

Kazakhstan’s tax legislation and regulations are subject to varying 
interpretations and instances of inconsistent opinions between local, regional, 
and national tax authorities and courts are not unusual. Taking this into 
account, while management believes that it is likely that the ruling in 
Zhaikmunai’s favour will be upheld on appeal, management assesses the risk of 
an unfavourable outcome for Zhaikmunai in pending and future legal 
proceedings and resulting payment of the above-mentioned claimed amounts 
of taxes and penalties as possible. 

AAbbaannddoonnmmeenntt  aanndd  ssiittee  rreessttoorraattiioonn  ((ddeeccoommmmiissssiioonniinngg))  

As Kazakh laws and regulations concerning site restoration and clean-up 
evolve, the Group may incur future costs, the amount of which is currently 
indeterminable. Such costs, when known, will be provided for as new 
information, legislation and estimates evolve.

31. Financial risk management objectives and policies 

The Group’s principal financial liabilities comprise borrowings, payables to the 
Government of Kazakhstan, trade payables and other current liabilities. The 
main purpose of these financial liabilities is to finance the Group’s operations. 
The Group's financial assets consist of trade and other receivables and cash 
and cash equivalents that derive directly from its operations. 

The Group is exposed to commodity price risk, foreign currency risk, liquidity 
risk and credit risk. The Group’s senior management oversees the 
management of these risks. The Group’s senior management ensures that the 
Group’s financial risk activities are governed by appropriate policies and 
procedures and that financial risks are identified, measured and managed in 
accordance with the Group’s policies and risk objectives. The Board of 
Directors reviews and agrees policies for managing each of these risks, which 
are summarised below. 

CClliimmaattee  cchhaannggee  

Management has considered how the Group’s identified climate risks and 
climate related goals (as discussed in Climate Change and GHG Emissions in the 
Group’s 2023 Annual Report) may impact the estimation of the recoverable 
value of cash-generating unit tested for impairment. The anticipated extent 
and nature of the future impact of climate on the Group’s operations and 
future investment depends on the development of new technologies and 
production processes employed and the level of emissions, energy efficiency 
and use of renewable energy. The sensitivity of the Group’s impairment 
assessment to these factors is also impacted by the extent that estimated 
recoverable value exceeds the carrying value of an individual cash-generating 
unit – where this is lower there is an increased risk of a future impact. The 
Group is in the process of identifying a range of actions and initiatives to 
progress towards the Group’s goals, including reduction of greenhouse gas 
emissions, wastewater discharges and increase of waste utilisation. In certain 
cases, the costs of such actions have been quantified and are included in the 
Group’s forecasts which are used to estimate recoverable value for the Group’s 
cash-generating unit. Other actions and initiatives continue to be explored by 
the Group but are not sufficiently certain to be reflected in the Group’s 
forecasts of estimated recoverable value.  

CCoommmmooddiittyy  pprriiccee  rriisskk  

The Group is exposed to the effect of fluctuations in price of crude oil, which is 
quoted in US dollar on the international markets. The Group prepares annual 
budgets and periodic forecasts including sensitivity analyses in respect of 
various levels of crude oil prices in the future. 

IInntteerreesstt  rraattee  rriisskk  

The Group is not exposed to interest rate risk in 2023 and 2022 as the Group 
had no financial instruments with floating rates as at years ended 31 December

As a significant portion of the Group’s operation is Tenge denominated, the 
Group’s statement of financial position can be affected by movements in the 
US dollar / Tenge exchange rates. The Group mitigates the effect of its 
structural currency exposure by borrowing in US dollars and denominating 
sales in US dollars.  

The following table demonstrates the sensitivity to a reasonably possible 
change in the US dollar exchange rate, with all other variables held constant.

A devaluation of Tenge against US dollar by 21% would lead to decrease in the 
net Tenge liability position by US$8,355 thousand as of 31 December 2023 and 
respective reduction of the loss before income tax for the year ended 
31 December 2023. The impact on equity is the same as the impact on profit 
before tax.

Liquidity risk is the risk that the Group will encounter difficulty in raising funds 
to meet commitments associated with its financial liabilities. The Group 
monitors its risk to a shortage of funds using a liquidity planning tool. The tool 
allows selecting severe stress test scenarios (for more details see Viability 
statement on pages 39-40 of the Annual Report). To ensure an adequate level 
of liquidity a minimum cash balance has been defined as a cushion of liquid 
assets. The Group’s objective is to maintain a balance between continuity and 
diversity of funding and flexibility through the use of notes, export financing 
and leases.  

The successful completion of the 2025 and 2022 Notes restructuring efforts 
has enhanced the Group's liquidity position and provided a more sustainable 
debt profile. The Directors confirm their expectation that the Group will 
continue to operate and meet its obligations as they fall due through the three-
year viability assessment period ending 31 December 2025. 

For more information on analysis of the Group’s ability to meet its liabilities on 
repayment of the Notes please see “Viability statement” section on the Annual 
report on pages 39-40.

For the purpose of the Group’s capital management, capital includes issued 
capital, additional paid-in capital and all other equity reserves attributable to 
the equity holders of the parent. The primary objective of the Group’s capital 
management is to maximise the shareholder value.  

Since the engagement with the AHG in discussions on potential restructuring of 
the Notes and signing of the FBAs in 2020 (see Note 1), the Group’s focus was 
on maintaining short-term liquidity and preserving cash. Successful cost 
optimisation programme, favourable hydrocarbon pricing and successful 
restructuring enabled the Group to grow its unrestricted cash balances to the 
level of US$161,711 thousand as at 31 December 2023. After successful 
implementation of the restructuring, the Group is in the process of revising its 
capital management policy in line with new requirements of SSN and SUN trust 
deeds and shareholder expectations.

On February 21, 2024 the Parent announced the successful completion of the 
delisting process for its ordinary shares from the Official List of the Astana 
International Exchange.

In Q1 2024, the well appraisal operations on Stepnoy Leopard Fields were 
nearly complete and significant data has been collected that included well flow 
rates, fluid contacts, and fluid and reservoir properties across a logged interval 
with c. 50-meter of net-pay. The flow-rate and pressure build-up tests 
confirmed high well productivity potential. The positive results obtained to 
date supported the commercial potential of the fields, hence in March 2024 
the Company made a final investment decision (“FID”) for the initial field 
development phase of the Stepnoy Leopard Fields with the forecast total 
capital budget for this initial field development phase of US$100 million gross. 
The Company plans to compile a Competent Person’s Report (CPR) to reclassify 
specific resources into reserves.

Following the approval of two-well drilling programme at the Chinarevskoye 
field in 2023, the first well (CHN-301) was spudded in December of 2023 with 
drilling in Q1 2024 to total depth of 4,980 meters on time and on budget, and 
awaiting completion operations with start-up expected mid-2024. It had 
multiple in-fill targets across the Carboniferous and Devonian age reservoirs. 
Hydrocarbons (oil, gas-condensate) have been encountered across three key 
intervals. The results are in line with our expectations of initial well rates of 400 
to 700 boepd. Next, the drilling rig will be moved to well No.41, with expected 
spud in April and start-up in Q3 2024. This well is a sidetrack and carries a 
higher level of geologic risk as it is a step-out from the existing well control in 
the targeted Devonian reservoir. If successful, these wells will enable a cost-
effective means of converting the field’s 2P reserves to PDP whilst also 
complying with Zhaikmunai’s PSA obligations. 

Credit risk is the risk that a counterparty will not meet its obligations under a 
financial instrument or customer contract, leading to a financial loss. The 
Group is exposed to credit risk from its operating activities (primarily trade 
receivables) and from its financing activities, including deposits with banks and 
financial institutions and foreign exchange transactions. 

The Group places its cash and deposits primarily with Citibank, N.A., and Halyk 
bank JSC with most recent credit ratings from Moody's rating agency of Aa3 
(Stable), and Baa2 (Stable), respectively. 

The Group sells its products and makes advance payments only to recognised, 
creditworthy third parties. In addition, receivable balances are monitored on 
an ongoing basis with the result that the Group’s exposure to bad debts and 
recoverability of prepayments made is not significant and thus risk of credit 
default is low. Also, the Group’s policy is to mitigate the payment risk on its off-
takers by requiring all purchases to be prepaid or secured by a letter of credit 
from an international bank. 

The Group considers a financial asset in default when contractual payments 
are 90 days past due, however certain exceptions can be made depending on 
the particular circumstances and discussions with the counterparty. Also, in 
certain cases, the Group may also consider a financial asset to be in default 
when internal or external information indicates that the Group is unlikely to 
receive the outstanding contractual amounts in full before taking into account 
any credit enhancements held by the Group. A financial asset is written off 
when there is no reasonable expectation of recovering the contractual cash 
flows. 

An impairment analysis is performed at each reporting date on an individual 
basis for major clients. The maximum exposure to credit risk at the reporting 
date is the carrying value of each class of financial assets. The Group does not 
hold collateral as security. The Group evaluates the concentration of risk with 
respect to trade receivables as low, as its customers are located in several 
jurisdictions and industries and operate in largely independent markets. The 
Group’s maximum exposure to credit risks is represented by its balances of 
cash and cash equivalents and restricted cash (Note 11). 

FFaaiirr  vvaalluueess  ooff  ffiinnaanncciiaall  iinnssttrruummeennttss  

Management assessed that the fair value of cash and cash equivalents, trade 
receivables, trade payables and other current liabilities approximate their 
carrying amounts at 31 December 2023 and 31 December 2022.  

Set out below, is a comparison by class of the carrying amounts and fair value 
of the Group’s financial instruments, other than those with carrying amounts 
reasonably approximating their fair values:

The fair value of the financial assets and liabilities represents the amount at 
which the instruments could be exchanged in a current transaction between 
willing parties, other than in a forced or liquidation sale. Fair value of the 
quoted notes is based on price quotations at the reporting date and 
respectively categorised as Level 1 within the fair value hierarchy.  

During the year ended 31 December 2023 and year ended 31 December 2022 
there were no transfers between the levels of fair value hierarchy of the 
Group’s financial instruments.

The Company and its wholly-owned subsidiaries 
are hereinafter referred to as “the Group”. 

On 14 October 2022, a new company Nostrum Oil 
& Gas Holding Limited was incorporated with a 
registered address of 20 Eastbourne Terrace, 
London, W2 6LG, UK. The entity is a wholly owned 
subsidiary of the Parent. 

On 12 December 2023, Nostrum Oil & Gas UK 
Limited was dissolved. 

2.  Basis of preparation  

BBaassiiss  ooff  pprreeppaarraattiioonn  

The Company financial statements for the year 
ended 31 December 2023 have been prepared on 
a going concern basis and in accordance with UK 
Adopted International Accounting Standards and 
the Companies Act 2006 in so far as it is applicable 
when reporting under UK adopted IAS. 

The Company financial statements have been 
prepared based on a historical cost basis. The 
Company financial statements are presented in 

subscribe for an additional 1.11% of the 
ordinary share capital of the Company 
upon exercise – increasing noteholder 
ownership of the Company to 90.00%; 
•  The existing ordinary shareholders will 

hold 11.11% upon closing of the 
restructuring. The existing ordinary 
shareholders will be diluted to 10.00% if 
the warrants held by existing noteholders 
are exercised; 

New corporate governance arrangements:  
•  in respect of the Group and certain 

arrangements regarding future utilization 
of the Group's cashflows. This includes a 
cash sweep mechanism requiring that cash 
above US$30 million is swept into a debt 
service retention account (to fund the next 
two cash interest payments due) and a 
restricted cash account which the 
Company can access with approval of the 
majority of Independent Non-Executive 
Directors of the Company; and 

•  Transfer the Company's listing to the 

Standard Listing segment of the London 
Stock Exchange. 

Restructuring completion 

On 9 February 2023, the Restructuring was 
implemented on the key terms as agreed under 
Lockup Agreement, and pursuant to the terms of 
the Scheme sanctioned by the Court on 26 August 
2022. This led to the sub-division and consolidation 
of the Company's share capital, which resulted in a 
reduction of shares from approximately 1,693.8 
million to 169.4 million following a 10:1 
consolidation. By 10 February 2023, 150,563,304 
new shares were listed on the London Stock 
Exchange (ticker symbol NOG.L), and by 13 
February, also on the Astana International 
Exchange. The new notes and warrants were listed 
on The International Stock Exchange from 9 
February 2023, while no new securities were listed 
on Euronext Dublin. On 14 March 2023, the 
Company’s ordinary shares were delisted from the 
official list of the Kazakhstan Stock Exchange 
(KASE). 

contingent liabilities. However, as at the reporting 
sheet date, the Company believes there is no 
material impact on the balance sheet carrying 
values of assets or liabilities. This is not considered 
a significant estimate. 

Group debt restructuring 

On 31 March 2020, the Group announced that it 
would seek to engage with its bondholders 
regarding a possible restructuring of the Group’s 
US$725 million 8.0% Senior Notes due July 2022 
(“2022 Notes”) and its US$400 million 7.0% Senior 
Notes due February 2025 (“2025 Notes”) 
(together, the “Existing Notes”).  

On 23 December 2021, the Group entered into a 
lock-up agreement (the “First LUA”) and agreed 
terms of a restructuring with noteholders. The 
below outlines the key terms of the restructuring 
as agreed between the Group, acceded 
noteholders and ICU in the LUAs and also voted in 
favour of by Nostrum shareholders: 

Partial reinstatement of debt: 
•  In the form of US$250 million Senior 

Secured Notes (SSNs) maturing on 30 
June 2026 and bearing interest at a rate of 
5.00% per year payable in cash. The SSNs 
are not convertible; 

•  In the form of US$300 million Senior 

Unsecured Notes (SUNs) maturing on 30 
June 2026 and bearing interest at a rate of 
1.00% per year payable in cash and 
13.00% per year payable in kind. If not 
repaid in cash at maturity, the SUNs are 
repayable in specie through the issuance 
of equity in the Company based on the 
value of the SUNs outstanding on the 
issuance date as a percentage of the fair 
market value of the Company (up to a 
maximum of 99.99% of the Company’s 
fully diluted equity); 

Conversion to equity:  
•  Conversion of the remainder of the 

Existing Notes and accrued interest into 
equity by way of a UK scheme of 
arrangement:  

•  Existing noteholders own 88.89% of the 
expanded ordinary share capital of the 
Company on closing of the restructuring. 
Existing noteholders also own warrants (to 
be held by trustee) allowing them to 

US dollars and all values are rounded to the 
nearest thousands, except when otherwise 
indicated. 

The Company recognises that there may be 
potential financial implications in the future from 
changes in legislation and regulation implemented 
to address climate change risk. Over time these 
changes may have an impact across a number of 
areas of accounting including asset impairment, 
increased costs, provisions, onerous contracts and

These financial statements have been prepared on 
a going concern basis. The Company is dependent 
on liquidity generated by its subsidiaries to 
continue in operation and its ability to meet its 
liabilities as they become due for the foreseeable 
future, a period of not less than 12 months from 
the date of these financial statements.  

Respectively, the Group level going concern 
matters and analysis are considered directly 
relevant for the Company (please refer to page 46 
of the Annual Report for more details). The 
directors are satisfied that the Group will have 
sufficient resources to continue in operation for 
the foreseeable future, a period of not less than 12 
months from the date of these financial 
statements. In addition, the Group has controls in 
place over allocation of resources among parent 
and subsidiaries. 

Taking into account the abovementioned 
considerations the directors are satisfied that the 
Company has sufficient resources to continue in 
operation for the foreseeable future, a period of 
not less than 12 months from the date of this 
report. Accordingly, they continue to adopt the 
going concern basis in preparing these parent

The Company applied for the first-time certain 
standards and amendments, which are effective 
for annual periods beginning on or after 1 January 
2023. The Company has not early adopted any 
other standard, interpretation or amendment that 
has been issued but is not yet effective. 

IFRS 17 Insurance Contracts  

IFRS 17 Insurance Contracts is a comprehensive 
new accounting standard for insurance contracts 
covering recognition and measurement, 
presentation and disclosure. IFRS 17 replaces IFRS 
4 Insurance Contracts. IFRS 17 applies to all types 
of insurance contracts (i.e., life, non-life, direct 
insurance and re-insurance), regardless of the type 
of entities that issue them as well as to certain 
guarantees and financial instruments with 
discretionary participation features; a few scope 
exceptions will apply. The overall objective of IFRS 
17 is to provide a comprehensive accounting 
model for insurance contracts that is more useful 
and consistent for insurers, covering all relevant 
accounting aspects. IFRS 17 is based on a general 
model, supplemented by:  

• A specific adaptation for contracts with direct 
participation features (the variable fee approach)  

• A simplified approach (the premium allocation 
approach) mainly for short-duration contracts  
The new standard had no impact on the 
Company’s financial statements.  

Definition of Accounting Estimates - 
Amendments to IAS 8  
The amendments to IAS 8 clarify the distinction 
between changes in accounting estimates, 
changes in accounting policies and the 
correction of errors. They also clarify how 
entities use measurement techniques and 
inputs to develop accounting estimates.  
The amendments had no impact on the 
Company’s financial statements.  

Disclosure of Accounting Policies - 
Amendments to IAS 1 and IFRS Practice 
Statement 2  
The amendments to IAS 1 and IFRS Practice 
Statement 2 Making Materiality Judgements 
provide guidance and examples to help entities 
apply materiality judgements to accounting 
policy disclosures. The amendments aim to help 
entities provide accounting policy disclosures 
that are more useful by replacing the 

requirement for entities to disclose their 
‘significant’ accounting policies with a 
requirement to disclose their ‘material’ 
accounting policies and adding guidance on 
how entities apply the concept of materiality in 
making decisions about accounting policy 
disclosures.  
The amendments have had no impact on the 
Company’s disclosures of accounting policies, 
the measurement, recognition or presentation 
of any items in the Group’s financial 
statements.  

Deferred Tax related to Assets and Liabilities 
arising from a Single Transaction – 
Amendments to IAS 12  
The amendments to IAS 12 Income Tax narrow 
the scope of the initial recognition exception, so 
that it no longer applies to transactions that 
give rise to equal taxable and deductible 
temporary differences such as leases and 
decommissioning liabilities.  
The amendments had no impact on the 
Company’s financial statements. 

SSttaannddaarrddss  iissssuueedd  bbuutt  nnoott  yyeett  eeffffeeccttiivvee  

The new and amended standards and 
interpretations that are issued, but not yet 
effective, up to the date of issuance of the 
Company’s financial statements are disclosed 
below. The Company intends to adopt these 
new and amended standards and 
interpretations, if applicable, when they 
become effective.  

Amendments to IFRS 16: Lease Liability in a Sale 
and Leaseback 
In September 2022, the IASB issued 
amendments to IFRS 16 to specify the 
requirements that a seller-lessee uses in 
measuring the lease liability arising in a sale and 
leaseback transaction, to ensure the seller-
lessee does not recognise any amount of the 
gain or loss that relates to the right of use it 
retains. 
The amendments are effective for annual 
reporting periods beginning on or after 1 
January 2024 and must applied retrospectively 
to sale and leaseback transactions entered into 
after the date of initial application of IFRS 16. 
Earlier application is permitted and that fact 
must be disclosed. 
The amendments are not expected to have a 
material impact on the Company’s financial 
statements.

Amendments to IAS 1: Classification of Liabilities 
as Current or Non-current 

In January 2020 and October 2022, the IASB 
issued amendments to paragraphs 69 to 76 of 
IAS 1 to specify the requirements for classifying 
liabilities as current or non-current. The 
amendments clarify: 
• What is meant by a right to defer settlement 
• That a right to defer must exist at the end of 
the reporting period 
• That classification is unaffected by the 
likelihood that an entity will exercise its deferral 
right 
• That only if an embedded derivative in a 
convertible liability is itself an equity instrument 
would the terms of a liability not impact its 
classification.  
In addition, a requirement has been introduced 
to require disclosure when a liability arising 
from a loan agreement is classified as non-
current and the entity’s right to defer 
settlement is contingent on compliance with 
future covenants within twelve months. 
The amendments are effective for annual 
reporting periods beginning on or after 1 
January 2024 and must be applied 
retrospectively. The Company is currently 
assessing the impact the amendments will have 
on current practice and whether existing loan 
agreements may require renegotiation. 

Supplier Finance Arrangements - Amendments to 
IAS 7 and IFRS 7 
In May 2023, the IASB issued amendments to 
IAS 7 Statement of Cash Flows and IFRS 7 
Financial Instruments: Disclosures to clarify the 
characteristics of supplier finance arrangements 
and require additional disclosure of such 
arrangements. The disclosure requirements in 
the amendments are intended to assist users of 
financial statements in understanding the 
effects of supplier finance arrangements on an 
entity’s liabilities, cash flows and exposure to 
liquidity risk. 
The amendments will be effective for annual 
reporting periods beginning on or after 
1 January 2024. Early adoption is permitted, but 
will need to be disclosed. 

The amendments are not expected to have a 
material impact on the Company’s financial 
statements.

FFoorreeiiggnn  ccuurrrreennccyy  ttrraannssllaattiioonn  

The functional currency is the currency of the 
primary economic environment in which an entity 
operates and is normally the currency in which the 
entity primarily generates and expends cash.  

Transactions in foreign currencies are initially 
recorded at their respective functional currency 
spot rates at the date the transaction first qualifies 
for recognition. 

The functional currency of the Company is the 
United States dollar (the “US dollar” or “US$”).  

IInnvveessttmmeennttss

Investments in subsidiaries are recorded at cost. 
Subsequently, the Company determines whether it 
is necessary to recognise an impairment loss on its 
investment in a subsidiary. At each reporting date, 
the Company determines whether there is objective 
evidence that the investment in the subsidiary is 
impaired. If there is such evidence, the Company 
calculates the amount of impairment as the 
difference between the recoverable amount of the 
subsidiary and its carrying value, and then 
recognises the impairment loss in the statement of 
profit or loss. 

FFiinnaanncciiaall  aasssseettss

Initial recognition and measurement  

Financial assets are classified, at initial recognition, 
as subsequently measured at amortised cost, fair 
value through other comprehensive income (OCI), 
and fair value through profit or loss. The Company 
determines the classification of its financial assets at 
initial recognition. 

The classification of financial assets at initial 
recognition depends on the financial asset’s 
contractual cash flow characteristics and the 
Company’s business model for managing them. 
With the exception of trade receivables that do not 
contain a significant financing component or for 
which the Company has applied the practical 
expedient, the Company initially measures a 
financial asset at its fair value plus, in the case of a 
financial asset not at fair value through profit or loss, 
transaction costs.  

In order for a financial asset to be classified and 
measured at amortised cost or fair value through 
OCI, it needs to give rise to cash flows that are 
‘solely payments of principal and interest (SPPI)’ on 
the principal amount outstanding. This assessment 
is referred to as the SPPI test and is performed at an 
instrument level. 

The Company’s business model for managing 
financial assets refers to how it manages its financial 
assets in order to generate cash flows. The business 
model determines whether cash flows will result 
from collecting contractual cash flows, selling the 
financial assets, or both. 

Purchases or sales of financial assets that require 
delivery of assets within a time frame established by 
regulation or convention in the market place 
(regular way trades) are recognised on the trade 

Monetary assets and liabilities denominated in 
foreign currencies are translated at the functional 
currency spot rates of exchange at the reporting 
date. All differences are taken to the profit or loss.  

Significant estimates and assumptions: impairment 
of investments in subsidiaries 

Determination as to whether, and by how much, 
the investment in a subsidiary is impaired involves 
management’s best estimates on highly uncertain 
matters such as future revenues of the subsidiary, 
operating expenses, discount rate, as well as fiscal 
regimes.  

Since 2019, the Company have been recording 
impairment for the full amount of the investments 
in Nostrum Oil & Gas Coöperatief U.A. and Nostrum 
Oil & Gas B.V. (Note 5), which has been  recognised 
in view of the decrease in the net assets of these 
subsidiaries, and the reduction of the 2P reserves 

date, i.e., the date that the Company commits to 
purchase or sell the asset. 

Financial assets at amortised cost (debt 
instruments) 

This category is the most relevant to the Company. 
The Company measures financial assets at 
amortised cost if both of the following conditions 
are met: 
•  The financial asset is held within a business model 
with the objective to hold financial assets in order 
to collect contractual cash flows, and 

•  The contractual terms of the financial asset give 
rise on specified dates to cash flows that are 
solely payments of principal and interest on the 
principal amount outstanding. 

Financial assets at amortised cost are subsequently 
measured using the effective interest (EIR) method 
and are subject to impairment. Gains and losses are 
recognised in profit or loss when the asset is 
derecognised, modified or impaired. 

The Company’s financial assets at amortised cost 
include cash and receivables from related parties.  

Derecognition 

A financial asset (or, where applicable, a part of a 
financial asset or part of a group of similar financial 
assets) is primarily derecognised (i.e., removed from 
the Company’s statement of financial position) 
when: 
•  The rights to receive cash flows from the asset 

have expired; or 

•  The Company has transferred its rights to receive 
cash flows from the asset or has assumed an 
obligation to pay the received cash flows in full 
without material delay to a third party under a 
‘pass-through’ arrangement; and either (a) the 

Non-monetary items that are measured in terms of 
historical cost in a foreign currency are translated 
using the exchange rates as at the dates of the initial 
transactions. Non-monetary items measured at fair 
value in a foreign currency are translated using the 
exchange rates at the date when the fair value is 
determined. 

expected to be recovered from the main operating 
subsidiary of the Company over the period of 2020-
2032, with the relevant decrease in the expected 
future net cash proceeds of Nostrum Oil & Gas 
Coöperatief U.A. 

As at 31 December 2023, impairment for the full 
amount of investments in Nostrum Oil & Gas 
Coöperatief U.A. and Nostrum Oil & Gas B.V. 
remained appropriate taking into account no 
significant changes in the assessments of 
recoverability of these investments.  

Company has transferred substantially all the risks 
and rewards of the asset, or (b) the Company has 
neither transferred nor retained substantially all 
the risks and rewards of the asset, but has 
transferred control of the asset. 

When the Company has transferred its rights to 
receive cash flows from an asset or has entered into 
a pass-through arrangement, it evaluates if, and to 
what extent, it has retained the risks and rewards of 
ownership. When it has neither transferred nor 
retained substantially all of the risks and rewards of 
the asset, nor transferred control of the asset, the 
Company continues to recognise the transferred 
asset to the extent of its continuing involvement. In 
that case, the Company also recognises an 
associated liability. The transferred asset and the 
associated liability are measured on a basis that 
reflects the rights and obligations that the Company 
has retained. 

Impairment of financial assets 

The Company recognises an allowance for expected 
credit losses (ECLs) for all debt instruments not held 
at fair value through profit or loss. ECLs are based on 
the difference between the contractual cash flows 
due in accordance with the contract and all the cash 
flows that the Company expects to receive, 
discounted at an approximation of the original 
effective interest rate. The expected cash flows will 
include cash flows from the sale of collateral held or 
other credit enhancements that are integral to the 
contractual terms.

ECLs are recognised in two stages. For credit 
exposures for which there has not been a significant 
increase in credit risk since initial recognition, ECLs 
are provided for credit losses that result from 
default events that are possible within the next 12-
months (a 12-month ECL). For those credit 

exposures for which there has been a significant 
increase in credit risk since initial recognition, a loss 
allowance is required for credit losses expected over 
the remaining life of the exposure, irrespective of 
the timing of the default (a lifetime ECL). 

For trade receivables and contract assets, the 
Company applies a simplified approach in 
calculating ECLs. Therefore, the Company does not 
track changes in credit risk, but instead recognises a 
loss allowance based on lifetime ECLs at each 
reporting date. 

FFiinnaanncciiaall  lliiaabbiilliittiieess  

Initial recognition, measurement and 
derecognition 

Financial liabilities are classified, at initial 
recognition, as financial liabilities at fair value 
through profit or loss, long-term borrowings, 
payables, or as derivatives designated as hedging 
instruments in an effective hedge, as appropriate.  

All financial liabilities are recognised initially at fair 
value and, in the case of long-term borrowings and 
payables, net of directly attributable transaction 
costs. 

FFiinnaanncciiaall  gguuaarraanntteeeess  

The Company’s financial liabilities include trade 
payables, payables related parties and financial 
guarantee liabilities. 

Subsequent measurement 

For purposes of subsequent measurement, financial 
liabilities are classified in two categories: 
Financial liabilities at fair value through profit or loss 
Financial liabilities at amortised cost (loans and 

borrowings) 

Financial guarantee is initially recognised in the 
financial statements at fair value at the time the 
guarantee is issued. The Company estimates the fair 
value of the financial guarantee contract as the 
difference between the net present value of the 
contractual cashflows required under a debt 
instrument, and the net present value of the net 
contractual cashflows that would have been 
required without the guarantee. The present value 
is calculated using a risk-free interest rate.  

Subsequent to initial recognition, the Company’s 
liability under each guarantee is measured at the 
higher of the amount initially recognised less 
cumulative amortisation recognised in profit and 
loss, and the amount of expected credit losses (ECL). 
Financial guarantee ECL reflect the cash shortfalls 
adjusted by the risks that are specific to the 
cashflows. If the ECL exceeds the initially recognised 
guarantee amount less cumulative amortisation the 
difference is taken to profit and loss. 

SShhaarree--bbaasseedd  ppaayymmeennttss  

The cost of cash-settled equity-based employee 
compensation is measured initially at fair value at 
the grant date. This fair value is expensed over the 
period until vesting with the recognition of a 
corresponding liability. The liability is remeasured at 
each reporting date up to and including the 
settlement date with changes in fair value 
recognised in the statement of comprehensive 
income. 

The cost of equity-settled transactions is measured 
at fair value at the grant date. This fair value is 
expensed over the period until vesting with the 
recognition of a corresponding equity element, 
which is not remeasured subsequently until the 
settlement date. 

Estimating fair value for share-based payment 
transactions requires determination of the most 
appropriate valuation model, which is dependent 

Derecognition 

A financial liability is derecognised when the 
obligation under the liability is discharged or 
cancelled or expires. When an existing financial 
liability is replaced by another from the same lender 
on substantially different terms, or the terms of an 
existing liability are substantially modified, such an 
exchange or modification is treated as the 
derecognition of the original liability and the 
recognition of a new liability. The difference in the 
respective carrying amounts is recognised in the 
statement of profit or loss. 

A financial guarantee liability is derecognised when 
the liability underlying the guarantee is discharged 
or cancelled or expires, or if the guarantee is 
withdrawn or cancelled. The carrying amount of the 
financial guarantee is taken to the statement of 
profit or loss. 

on the terms and conditions of the grant. This 
estimate also requires determination of the most 
appropriate inputs to the valuation model including 
the expected life of the share option, volatility and 
distribution yield and making assumptions about 
them. The assumptions and models used for 
estimating fair value for share-based payment 
transactions are disclosed in Note 13.

In May 2023, the Company performed a corporate reorganisation, namely, in 
return for the transfer and assignment by the Company of its membership and 
associated rights in Nostrum Oil & Gas Coöperatief U.A. and Nostrum Oil & Gas 
B.V., Nostrum Oil & Gas Holding Limited issued 100 new ordinary shares, which 
were allotted and issued to the Company. As a result of this reorganising the 
Company reallocated the cost of its investments in Nostrum Oil & Gas Coöperatief 
U.A. and Nostrum Oil & Gas BV for the total amount of US$106,741 thousand 
(excluding initial guarantee value of US$9,881 thousand) to investments to 
Nostrum Oil & Gas Holding Limited. 

In addition, the investments in Nostrum Oil & Gas Holding Limited include the 
US$810,473 thousand recognised as an equivalent of the Old Notes of Nostrum 
Oil & Gas Finance B.V., which were exchanged for the shares issued by the 
Company during the Restructuring process. Also, the Company acts as a guarantor 
under the Group’s SSNs and SUNs, which are issued in favour of the Company’s 
indirect subsidiaries, hence related costs in the amount of US$193,817 thousand 
at initial recognition are capitalised into the investments in subsidiaries. As a result 
of the impairment testing performed at 31 December 2023 the Company 
recognised an impairment charge of US$1,004,290 thousand for the full amount 
of these investments in the subsidiary.  

As at 31 December 2022, Nostrum Oil & Gas Cooperatief U.A. include the 
guarantees initial cost in the amount of US$9,881 thousand as described in the 
Note 9 as well as US$518 thousand capitalized costs under the “Long-term 
Incentive Plan 2017.  

As a result of the impairment testing performed at 31 December 2019 the 
Company recognised an impairment charge of US$117,361 thousand for the full 
amount of its investments in subsidiaries. For more details, please refer to

Receivables from the Nostrum Oil & Gas Benefit Trust (“the Trust”) represent the 
loan provided to support the Company’s obligations to employees under the 
Employee Share Option Plan (“ESOP”) and the Long-Term Incentive Plan 2017 
(“LTIP”) (Note 13). The loan is interest free and unsecured. The loan is repayable 
in the case of an advance used to acquire securities to satisfy the exercise of 
options granted pursuant to the rules of ESOP, and unless otherwise agreed in 
writing between the parties, the earlier of 1) ten years from the Date of Grant, or 
2) 30 days after the exercise date, and in all other cases any other date agreed in 
writing between the parties. 

Considering the fact that the loan is repayable to the extent of the assets of the 
Trust, which are reflected in treasury shares held by the Trust, the Company has 

recognised a bad debt allowance as at 31 December 2023 in the amount of 
US$65 thousand (2022: US$23,541 thousand), representing the difference 
between the book value of the loan and the recoverable value of the treasury 
shares as of 31 December 2023. 

7.  Cash and Cash Equivalents 

As at 31 December 2023 and 31 December 2022 cash and cash equivalents 
comprised US$160 thousand at the current accounts in Pound Sterling.  

8.  Shareholders’ equity 

As at 31 December 2023 the ordinary share capital of the Company consists of 
169,381,561 issued and fully paid ordinary shares, which are listed on the London 
Stock Exchange. The ordinary shares have a nominal value of GB£ 0.01. The table 
below represents movements in the number of ordinary shares during the year 
ended 31 December 2023. The movements in the number of shares during the 
year ended 31 December 2023 and 31 December 2022 was as follows:

As part of the Restructuring, on 9 February 2023 the Company issued 
1,505,633,046 new shares in connection with the repayment of the remaining 
face value of the Existing Notes following the issue of the New Notes (see Note 14 
below), together with accrued but unpaid interest (the “Debt for Equity Swap”). 
Given the number of new shares issued, at the close of business on 9 February 
2023 the Company also performed a share consolidation, so as to achieve an 
appropriate share price following closing of the Restructuring (Note 1). As a result, 
the number of ordinary shares in issue was reduced from 1,693,816,004 
(following the issue of the new shares) to 169,381,600 ordinary shares, on the 
basis of a 10:1 consolidation (the “Share Consolidation”). In order to give effect to 
the Share Consolidation, the Company initially reduced the nominal value of the 
ordinary shares (the “Sub-Division”) after the issue of the new shares, through 
sub-division of each ordinary share at a ratio of 1:10 into one ordinary share of 
nominal value of £0.001 each together with nine deferred shares of nominal value 
£0.001 each (the “Deferred Shares”). The Deferred Shares (in practice) have no 
economic or voting rights in the capital of the Company and it is expected that 
they will be cancelled following the implementation of the Restructuring. The 
nominal value of the ordinary shares following the Share Consolidation was £0.01 
each. Fractions of new ordinary shares were not issued in connection with the 
Share Consolidation and any fractional entitlements were rounded down to the 
nearest whole ordinary share.

Treasury shares were issued to support the Group’s obligations to employees 
under the Employee Share Option Plan (“ESOP”) and the Long-Term Incentive 
Plan (“LTIP”) and are held by Intertrust Employee Benefit Trustee Limited as 
trustee for the Nostrum Oil & Gas Benefit Trust. In the case of the ESOP, upon 
request from employees to exercise options, the trustee would sell shares on the 
market and settle respective obligations under the ESOP. In the case of share-
settled LTIP awards, the trustee would transfer shares to the relevant LTIP award 
holder (although no LTIP awards are currently exercisable). The Nostrum Oil & Gas 
Benefit Trust constitutes a special purpose entity under IFRS and therefore, the 
shares held in the trust are recorded as treasury capital of the Company.  

Group reorganisation reserve in the amount of US$255,459 thousand represents 
the difference between the partnership capital, treasury capital and additional 
paid-in capital of Nostrum Oil & Gas LP and the share capital of Nostrum Oil & Gas 
PLC, that arose during the reorganisation of the Group in 2014. Share-option 
reserves include amounts related to sale of treasury shares under ESOP as well as 
share-based payments under LTIP. 

Nostrum Oil & Gas PLC became the new holding company for the business of 
Nostrum Oil & Gas LP based on the resolution passed by its limited partners on 17 
June 2014 followed by the Company reorganisation referred to in that resolution.

13. Long-term incentive plan 

22001177  LLoonngg--tteerrmm  iinncceennttiivvee  ppllaann  

In 2017 the Company started operating a Long-term incentive plan (“the LTIP”), 
that was approved by the shareholders of the Company on 26 June 2017 and 
adopted by the board of directors of the Company on 24 August 2017. The LTIP is 
a discretionary benefit offered by the Company for the benefit of selected 
employees. Its main purpose is to increase the interest of the employees in the 
Company's long-term business goals and performance through share ownership. 
The LTIP is an incentive for the employees' future performance and commitment 
to the goals of the Company. The remuneration committee of the board of the 
Company has the right to decide, in its sole discretion, whether or not further 
awards will be granted in the future and to which employees those awards will be 
granted. 

Employees (including senior executives and executive directors) of members of 
the Group or their associates may receive an award, which is a "nominal cost 
option" over a specified number of ordinary shares in the capital of the Company. 
The option has an exercise price of 1p per share (but the Company has the 
discretion to waive this prior to exercise). In addition, under the Rules of the LTIP 
the Company has discretion to settle awards other than by transfer of shares such 
as by way of cash settlement. Generally, the awards are classified as equity-
settled transactions. The share options are treated as equity-settled since there 
are no legal limitations expected on issue of shares for these upon vesting, the 
Company has a choice of settlement and the intention is to settle them in equity. 
However, in certain jurisdictions due to regulatory requirements the Company 
may not be able to settle the awards other than by transfer of cash, in which case 
the awards are classified as cash-settled transactions, and accounted for similar to 
SARs.  

The award ordinarily vests and becomes exercisable as from later of the third 
anniversary of grant or two years after the date on which the Company 
determines whether the performance condition has been satisfied, subject to 
employee’s continued service and to the extent to which the performance 
condition is satisfied, until the end of the contractual life. The contractual life of 
the share options is ten years.  

The cost of cash-settled equity-based employee compensation is measured 
initially at fair value at the grant date using a trinomial lattice valuation model. 
This fair value is expensed over the period until vesting with the recognition of a 
corresponding liability. The liability is remeasured at each reporting date up to 
and including the settlement date with changes in fair value recognised in the 
statement of comprehensive income. 

The cost of equity-settled transactions is measured at fair value at the grant date 
using a trinomial lattice valuation model. This fair value is expensed over the 
period until vesting with the recognition of a corresponding equity element of 
“shares to be issued under LTIP”, which is not remeasured subsequently until the 
settlement date. 

The following table summarises the movement in the number of outstanding 
share options capable of vesting during the years ended 31 December 2023 and 
31 December 2022:

 In 2017 the Company granted 1,208,843 share options, of which 308,850 share 
options remained outstanding as at 31 December 2023 (2022: 325,423 share 
options). The weighted average remaining contractual life of share options 
outstanding as at 31 December 2023 was 4 years (2022: 5 years). On 23 March 
2018 the remuneration committee of the board of the Company determined the 
level of performance conditions that were met for the performance conditions set 
upon issue of the share options granted in 2017. After adjusting for the non-
achievement of performance conditions, 139,840 share options are capable of 
vesting as of 31 December 2023 (2022: 147,343 share options) and all of these 
share options were vested, in accordance with the management’s best estimate, 
and exercisable as of 31 December 2023. 

On 28 November 2018 the Company granted a further 1,163,040 share options, 
however due to the performance conditions not being met none of these share 
options are capable of vesting. 

The fair value of the equity-settled share options at the valuation dates of 
28 November 2018 and 23 March 2018 amounted to US$1.25 and US$2.76 per 
share option, respectively. Based on these estimations, during the year ended 31 
December 2023 the Company recognised a reduction in the investments in 
subsidiaries in the amounts of US$25 thousand (2022: US$38 thousand). 

Share options 

The Hull-White trinomial lattice valuation model was used to value the share 
options. The following table lists the inputs to the model used for valuation of the 
share options at the grant date: 

Price at the issue date (US$) 
Distribution yield (%) 
Expected volatility (%) 
Risk-free interest rate (%) 
Expected life (years) 
Option turnover (%) 
Price trigger 

10 October 2017 
1.25

11 December 2017 
2.76 
0% 
40.4% 
1.45% 
10 
10% 
2.0 

The expected life of the options is based on historical data and is not necessarily 
indicative of exercise patterns that may occur. The expected volatility reflects the 
assumption that the historical volatility is indicative of future trends, which may 
also not necessarily be the actual outcome. Option turnover rate represents the 
rate of employees expected to leave the Company during the vesting period, 
which is based on historical data and may not necessarily be the actual outcome. 
The model considers that when share price reaches the level of exercise price 
multiplied by the price trigger the employees are expected to exercise their 
options.

15. Financial risk management objectives and policies 

The Company’s financial assets consist of receivables from shareholders and cash 
and cash equivalents. The Company’s financial liabilities consist of payables to 
related parties, trade and other payables and accrued liabilities. 

The main risks arising from the Company’s financial instruments are foreign 
exchange risk and credit risk. The Company’s management reviews and agrees 
policies for managing each of these risks, which are summarized below. 

CClliimmaattee  cchhaannggee  

Management has considered how the Company’s identified climate risks and 
climate related goals (as discussed in Climate Change and GHG Emissions in the 
Group’s 2022 Annual Report) may impact the estimation of the recoverable value 
of cash-generating unit tested for impairment and therefore of the finance 
guarantee provision. The anticipated extent and nature of the future impact of 
climate on the Group’s operations and future investment depends on the 
development of new technologies and production processes employed and the 
level of emissions, energy efficiency and use of renewable energy. The sensitivity 
of the Group’s impairment assessment to these factors is also impacted by the 
extent that estimated recoverable value exceeds the carrying value of an 
individual cash-generating unit – where this is lower there is an increased risk of a 
future impact. The Group is in the process of identifying a range of actions and 
initiatives to progress towards the Group’s goals, including reduction of 
greenhouse gas emissions, wastewater discharges and increase of waste 
utilisation. In certain cases, the costs of such actions have been quantified and are 
included in the Group’s forecasts which are used to estimate recoverable value 
for the Group’s cash-generating unit. Other actions and initiatives continue to be 
explored by the Group but are not sufficiently certain to be reflected in the 
Group’s forecasts of estimated recoverable value.  

FFoorreeiiggnn  ccuurrrreennccyy  rriisskk  

Most of the Company’s operation is denominated in USD, therefore the 
Company’s statement of financial position is not significantly affected by exchange 
rate movements.  

IInntteerreesstt  rraattee  rriisskk  

The Company is not exposed to interest rate risk in 2022 and 2021 as the 
Company had no financial instruments with floating rates as at years ended 31 
December 2023 and 2022. 

LLiiqquuiiddiittyy  rriisskk  

Liquidity risk is the risk that the Company will encounter difficulty in raising funds 
to meet commitments associated with its financial liabilities. The Company is part 
of the Group’s monitoring process of its risk to a shortage of funds using a liquidity 
planning tool. The tool allows selecting severe stress test scenarios. To ensure an 
adequate level of liquidity a minimum cash balance has been defined as a cushion 
of liquid assets. The Group’s objective is to maintain a balance between continuity 
of funding and flexibility through the use of notes, export financing and leases, 
and adequately allocating funding among various entities in the Group.  

Following successful restructuring of the 2025 Notes and 2022 Notes, the 
Directors confirm that they have a reasonable expectation that the Company and 
the Group will continue in operation as they fall due through the three-year 
viability assessment period ending 30 June 2027. For more information on 
analysis of the Group’s ability to meet its liabilities on repayment of the Notes 
please see “Viability statement” section on the Annual report on pages 39-40.

CCrreeddiitt  rriisskk  

Financial instruments, which potentially subject the Company to credit risk, 
consist primarily of receivables and cash in banks. The maximum exposure to 
credit risk is represented by the carrying amount of each financial asset. The 
Company considers that its maximum exposure is reflected by the amount of 
receivables from shareholders and cash and cash equivalents. 

The Company places its US Dollar, British Pound and Euro denominated cash with 
Citibank which has a credit rating of Aa3 (stable) from Moody’s rating agency at 
31 December 2023. 

Receivables are amounts receivable from Group companies, thus risk of credit 
default is low, except for the loan receivable from the Trust for which loss 
allowance has been recognised. 

In addition to the direct credit exposures outlined above, the Company has also 
acted as a guarantor under the Group’s SSNs and SUNs. Since the guarantees are 
issued in favor of the Company’s indirect subsidiaries, related costs at initial 
recognition are capitalised into the investments in subsidiaries. The guarantees 
could potentially expose the Company to significant financial strain in the event of 
the default of the SSNs and SUNs. 

FFaaiirr  vvaalluueess  ooff  ffiinnaanncciiaall  iinnssttrruummeennttss  

The fair value of the financial assets represents the amount at which the 
instrument could be exchanged in a current transaction between willing parties, 
other than in a forced or liquidation sale. 

The management assessed that its assets and liabilities approximate their carrying 
amounts largely due to their nature or the short-term maturities of these 
instruments.  

CCaappiittaall  mmaannaaggeemmeenntt  

For the purpose of the Company’s capital management, capital includes issued 
capital and all other equity reserves attributable to the equity holders of the 
Company. The primary objective of the Company’s capital management is to 
maximise the shareholder value.  

16. Events after the reporting 

AAIIXX  ddeelliissttiinngg  

On February 21, 2024 the Company announced the successful completion of the 
delisting process for its ordinary shares from the Official List of the Astana 
International Exchange. 

UUppddaattee  oonn  SStteeppnnooyy  LLeeooppaarrdd  FFiieellddss  

In Q1 2024, the well appraisal operations on Stepnoy Leopard Fields were nearly 
complete and significant data has been collected that included well flow rates, 
fluid contacts, and fluid and reservoir properties across a logged interval with c. 
50-meter of net-pay. The flow-rate and pressure build-up tests confirmed high 
well productivity potential. The positive results obtained to date supported the 
commercial potential of the fields, hence in March 2024 the Company made a 
final investment decision (“FID”) for the initial field development phase of the 
Stepnoy Leopard Fields with the forecast total capital budget for this initial field 
development phase of US$100 million gross. The Company plans to compile a 
Competent Person’s Report (CPR) to reclassify specific resources into reserves. 

DDrriilllliinngg  pprrooggrraammmmee  

Following the approval of two-well drilling programme at the Chinarevskoye field 
in 2023, the first well (CHN-301) was spudded in December of 2023 with drilling in 
Q1 2024 to total depth of 4,980 meters on time and on budget, and awaiting 
completion operations with start-up expected mid-2024. It had multiple in-fill 
targets across the Carboniferous and Devonian age reservoirs. Hydrocarbons (oil, 
gas-condensate) have been encountered across three key intervals. The results 
are in line with our expectations of initial well rates of 400 to 700 boepd. Next, the 
drilling rig will be moved to well No.41, with expected spud in April and start-up in 
Q3 2024. This well is a sidetrack and carries a higher level of geologic risk as it is a 
step-out from the existing well control in the targeted Devonian reservoir. If 
successful, these wells will enable a cost-effective means of converting the field’s 
2P reserves to PDP whilst also complying with Zhaikmunai’s PSA obligations.

American Petroleum Institute.

The industry standard method of expressing specific density of crude oil or other liquid hydrocarbons 
as recommended by the American Petroleum Institute. Higher API gravities mean lower specific 
gravity and lighter oils. When the API gravity is greater than 10, the product is lighter and floats on 
water; when it is less than 10, it is heavier than water and sinks. Generally speaking, oil with an API 
gravity between 40 and 45 commands the highest prices.

but that are not currently considered commercially recoverable.

Cost oil denotes an amount of crude oil produced in respect of which the market value is equal to 
Nostrum’s monthly expenses that may be deducted pursuant to the PSA (q.v.) (including all operating 
costs, exploration costs and development costs up to an annual maximum of 90% of the annual gross 
realised value of hydrocarbon production).

A mixture of liquid hydrocarbons of different molecular weights.

During development, engineering teams design the most efficient development options to build wells 
and associated infrastructure to produce hydrocarbons from a gas field within a proven productive 
reservoir (as defined by exploration and appraisal activities). The three phases of development are 
exploration and appraisal, development and production.

Polymerase chain reaction testing, a test for COVID-19.

Hydrocarbons, whether solid, liquid or gaseous. The proportion of different compounds in a petroleum 
find varies from discovery to discovery. If a reservoir primarily contains light hydrocarbons, it is 
described as a gas field. If heavier hydrocarbons predominate, it is called an oil field. An oil field may 
feature free gas above the oil and contain a quantity of light hydrocarbons, also called associated gas.

Possible Reserves are those reserves that, to a low degree of certainty (10% confidence), are 
recoverable. There is relatively high risk associated with these reserves. Proven, Probable and Possible 
Reserves are referred to as 3P.

Probable Reserves are those reserves that analysis of geological and engineering data suggests are 
more likely than not to be recoverable. There is at least a 50% probability that reserves recovered will 
exceed Probable Reserves. Proven plus Probable Reserves are referred to as 2P.

Processing of saleable product from hydrocarbons sourced from oil wells and gas wells.

The mining allotment (Annex to the Licence), issued by the Competent Authority to Zhaikmunai LLP.

producing structure and characteristics are determined.

Profit oil is the difference between cost oil and the total amount of crude oil produced each month, 
which is shared between the State and Zhaikmunai LLP.

Quantities of petroleum which are estimated, on a given date, to be potentially recoverable from 
undiscovered accumulations.

Proven or Proved Reserves (1P) are those reserves that, to a high degree of certainty (90% confidence), 
are recoverable. There is relatively little risk associated with these reserves. Proven Developed 
Reserves are reserves that can be recovered from existing wells with existing infrastructure and 
operating methods. Proven Undeveloped Reserves require development.
