On 26 February 2018, a 7.5 magnitude 
earthquake, the largest in nearly 100 years, 
struck the PNG Highlands, causing much loss 
of life and damage within our local communities 
and resulting in the shut-in of all our production. 
In the immediate aftermath of the earthquake, 
Oil Search focused on three separate 
workstreams – providing relief to impacted 
communities, restoring our operated production 
and ensuring that ‘business as usual’ activities, 
including new LNG developments, continued. 
As one of the few organisations able to deliver 
rapid, on-the-ground assistance, Oil Search 
provided nearly 80% of all First Responder aid 
to local communities. Despite many challenges, 
we brought our first operated production back 
onstream within four weeks of the earthquake. 
The PNG LNG Project operator, ExxonMobil, 
used the opportunity while operations were 
shut-down to undertake debottlenecking and 
maintenance activities. Consequently, in the 
second half of 2018, the Project achieved 
the highest half-yearly production rate since 
it came onstream in 2014.

Oil Search coordinated the delivery of emergency supplies and 
provided medical treatment for villages devastated by the PNG 
Highlands earthquake.

During 2018, broad alignment was reached 
by Oil Search and its key joint venture partners 
on the preferred downstream concept for 
new LNG capacity in PNG. This comprises 
the construction of three 2.7 MTPA LNG trains 
at the PNG LNG plant site, two underpinned 
by the Elk-Antelope fields (Papua LNG Project) 
and one by the PNG LNG Project fields and 
P’nyang field. In November, the Papua LNG 
Project participants signed a Memorandum 
of Understanding with the PNG Government, 
which will form the basis for a Gas Agreement 
that equitably and appropriately allocates 
benefits and returns from the Papua LNG 
development among stakeholders. Broad 
agreement was also reached on commercial 
terms for the Papua LNG Project to access 
the PNG LNG plant site. Once finalised, 
these agreements, together with the P’nyang 
Gas Agreement, will allow an aligned 
entry into the FEED phase of the three-train 
development, which is well positioned to 
deliver high quality, cost-competitive LNG into 
the rapidly-growing Asian LNG market.

The proposed development of new LNG capacity in PNG 
includes the construction of three 2.7 MTPA LNG trains on  
the existing PNG LNG plant site.

Oil Search was the largest investor in oil and gas 
exploration in PNG in 2018, utilising our proven 
skills in exploring in extremely challenging, 
jungle-covered terrain requiring heli-support 
and complex logistics. We drilled two operated 
gas appraisal wells, Kimu 2 and Barikewa 3, 
in the Forelands region, both of which were 
successful. In the PNG Highlands, we drilled the 
successful P’nyang South 2 well and commenced 
drilling Muruk 2, both on behalf of ExxonMobil. 
In addition, we undertook two major 2D seismic 
programmes, in the Onshore Gulf, on behalf 
of ExxonMobil and Total, and in the Gobe 
area. The data acquired will help mature leads 
and prospects located near infrastructure for 
potential future drilling. With an estimated 30 
tcf of potential gas resource yet to be found, 
we continue to be at the forefront of testing new 
and proven plays in PNG. 

The Company’s exploration activities take place in some of  
the most remote and rugged terrain in PNG, requiring helicopter 
support to transport equipment and supplies.

In early 2018, we completed the acquisition 
and became operator of a range of leases on 
the Alaska North Slope in the US, including 
a major, undeveloped conventional onshore 
oil discovery. During the year, we built a 
multi-disciplinary, highly experienced, 
Anchorage-based team with material North 
Slope and international expertise. We also 
engaged with key stakeholder groups, to 
develop a greater understanding of the major 
issues and opportunities in Alaska. At the 
beginning of 2019, we expanded significantly 
our lease position on the North Slope, 
positioning the Company for long-term growth. 
Utilising the skills developed over many years 
in PNG, of operating in remote and challenging 
areas where logistics is critical, in late December 
we commenced drilling the first of two appraisal 
wells in the Pikka Unit, with the second 
spudding in early January. Subject to the results 
and regulatory approvals, we anticipate 
entering the FEED phase of this exciting new 
oil development in 2019. 

The acquisition of oil assets on the Alaska North Slope 
complements Oil Search’s existing high-quality PNG gas assets.

Oil Search has a range of initiatives and 
programmes reflecting its commitment to 
operating in a responsible way. As well as 
our response to the February earthquake, 
during the year we were a founding partner 
in the Bel isi PNG initiative, an innovative 
project where businesses work together 
collaboratively to address gender-based 
violence in PNG. We also continued to 
support the PNG Government to progress the 
distribution of PNG LNG Project benefits to 
communities. In line with our commitment to 
transparency, we were one of the first ASX-listed 
energy companies to release a TCFD-aligned 
Climate Change Resilience Report, which 
demonstrated the resilience of our portfolio in 
a range of decarbonisation scenarios. In Alaska, 
following consultation by Oil Search with 
local communities, the Final Environmental 
Impact Statement for the proposed Pikka 
Unit development was issued, highlighting 
our willingness to engage and respond 
to community expectations.

Oil Search’s long-standing commitment to developing  
and maintaining genuine relationships has been key  
to the Company’s ongoing success.

In 2018, Oil Search delivered a net profit after tax of US$341.2m, 13% higher 
than in 2017. This was a commendable result in light of the temporary shut-in 
of production following the PNG Highlands earthquake in February 2018.

Dear Shareholders,

2018 was an unprecedented year for 
Oil Search. 

In February, the PNG Highlands was 
devastated by a severe earthquake, 
which resulted in the temporary shut-in 
of all production and tragically, the loss 
of many lives within our surrounding 
communities. In the unfolding crisis, 
we prioritised ensuring the safety 
of our people, the protection of the 
environment and the integrity of our 
facilities. Due to the efforts of many, we 
were able to resume safe and reliable 
operations within a month of the 
earthquake, with zero incidents and no 
loss of hydrocarbon containment. In 
addition, as one of the few organisations 
in PNG able to provide rapid 
on-the-ground assistance, Oil Search 
provided much needed food, water 
and medical supplies to impacted 
communities as part of our US$5 
million contribution to support relief 
efforts. One year after the earthquake, 
the Company, in partnership with the 
Oil Search Foundation, continues to 
support the long-term recovery of 
local communities.

Despite the major interruption to our 
operations, Oil Search delivered a net 
profit of US$341 million, 13% higher 
than in the previous year, and generated 
a healthy operating cash flow of 
US$855 million, buoyed by stronger 
oil and LNG prices. The Company 
declared a total dividend for 2018 of 
10.5 US cents per share, 11% higher than 
in 2017, representing a dividend payout 
at the upper end of the Board’s stated 
dividend payment range of between 
35% and 50% of core net profit after tax.

Oil Search’s activities continued to 
be guided by our vision to generate 
top quartile returns for shareholders 
through excellence in socially 
responsible oil and gas exploration 
and production. During the year, 
significant progress was made on 
the world class Papua LNG and PNG 
LNG/P’nyang development projects in 
PNG and we completed the acquisition 
of an exciting portfolio of oil assets 

on the North Slope of Alaska. These 
high quality growth projects have the 
potential to double the Company’s 
annual production by the middle of 
the next decade, delivering significant 
value to shareholders as well as 
governments and local communities 
in PNG and Alaska. As highlighted in 
the 2018 Climate Change Resilience 
Report, Oil Search’s current and growth 
assets are highly robust and would 
continue to generate positive returns 
to shareholders under a range of 
decarbonisation scenarios, including a 
2°C pathway. 

There were several changes to the 
Oil Search Board in 2018. Gerea Aopi 
resigned as Executive Director, after 
12 years of dedicated service. The 
Company continues to benefit from 
Gerea’s extensive experience and 
relationships in PNG in his current role 
as PNG Country Chairman. Following 
an extensive international search, we 
welcomed Ms Susan Cunningham and 
Dr Bakheet Al Katheeri as non-Executive 
Directors to the Board. Susan and 
Bakheet’s considerable oil and gas 
experience complement the Board’s 
skills and will be particularly valuable 
as we work to deliver LNG expansion 
in PNG and unlock the value from our 
assets on the Alaska North Slope. 

During the year, we increased the 
number of Independent Members on 
our Board committees from three PNG 
citizens to six. The new appointees 
will gain considerable governance 
experience and deepen the pool of 
PNG talent while contributing to the 
effective functioning of the relevant 
Board committees with their local 
knowledge and well-established in-
country networks. 

A management reorganisation 
has commenced, to equip the 
Company with the talent, experience, 
accountabilities and reporting lines 
capable of delivering our operational 
and growth ambitions. As part of 
this, the Board is well advanced on 
succession planning and the search 
for, and assessment of, leadership 
talent. This includes a structured plan 

15

to manage the succession of your 
Managing Director, Peter Botten, 
who has led Oil Search for more than 
25 years. Peter has committed to 
guiding the Company through to the 
final investment decisions for each of 
our LNG developments, ensuring a 
smooth transition to new leadership. 
His deep commitment to PNG and 
focus on improving social development 
in-country will continue to support the 
Company through his role as Chairman 
of the Oil Search Foundation. The Board 
will keep shareholders fully informed as 
the succession process progresses.

In closing, I would like to recognise and 
thank all Oil Search employees for their 
outstanding resilience and dedication 
during what was a very challenging 
year. Through strong leadership, the 
Company maintained its focus on 
operational excellence, safety and 
sustainability, while also progressing its 
growth ambitions in PNG and Alaska. I 
would like to congratulate Peter for his 
award of the Companion of the Order 
of Australia, reflecting his commitment 
to PNG spanning almost 30 years. 
Thanks also go to my Board colleagues 
for their support and guidance through 
a period that tested every fibre of the 
Company’s capacity. Finally, I must 
acknowledge the long-standing 
support of our shareholders, who 
have played an important role in Oil 
Search’s remarkable growth story. 
As the Company enters its 90th year 
since incorporation in PNG, it has 
never been in a better position to 
continue to provide attractive returns 
to shareholders into the next decade.

Thank you.

Richard Lee, AM 
CHAIRMAN

During 2018, Oil Search experienced 
one of the most challenging years in 
the Company’s long history. The first 
half was dominated by the 7.5 
magnitude earthquake which struck 
the PNG Highlands on 26 February. 
This resulted in the temporary shutdown 
of all operated production and the PNG 
LNG Project and brought devastation 
to surrounding communities and 
infrastructure. It really is a miracle that 
none of our staff or contractors were 
seriously hurt during this event and the 
many aftershocks.

In the days following the earthquake, we 
were forced to evacuate approximately 
750 staff and contractors from our 24 
operating sites across earthquake-
devastated areas of the Highlands. 
However, many of our people stayed 
at, or returned to site, to shut down our 
facilities safely, address the challenges 
of re-establishing water, power 
and sanitation facilities to our camp 
infrastructure and to ensure the earliest 
possible return to safe, sustainable and 
reliable operations. We also played a 
critical first responder role within our 
local communities, which sustained 
widespread damage including the 
destruction of houses, gardens, roads, 
bridges, schools and health facilities. 
The United Nations estimates that we 
delivered approximately 80% of total 
food supplies to affected areas in the first 
four weeks following the earthquake. 
Our employees and contractors showed 
excellent courage and professionalism 
and went well beyond the call of duty, 
performing tasks outside their normal 
roles to protect our people, environment 
and facilities. I would like to thank them 
all sincerely for their efforts. 

Following an intense period of 
hard work, operated production 
recommenced in April, initially from 
the Kutubu field, while the PNG 
LNG Project resumed production 
in May. Due to maintenance and 
other works undertaken on the PNG 
LNG Project during the period of 
downtime, the PNG LNG Project 
delivered a record half year annualised 
production rate of 8.8 MTPA, almost 

Oil Search delivered approximately 80% of total food supplies to impacted communities  
in the first four weeks following the earthquake.

30% above nameplate capacity. The 
strong performance at the PNG LNG 
Project is expected to be sustainable, 
underpinned by the Project’s strong 
reserves position, which was upgraded 
following recertification of the Project 
fields in 2016. Our operated production 
continues to ramp up as the remaining 
facilities that were impacted by the 
earthquake are returned to service. 

Despite a 17% decline in production 
for the year, Oil Search delivered a 
net profit of $341 million, 13% higher 
than the prior year. Stronger global oil 
and gas prices more than offset lower 
production and higher production costs 
relating to earthquake remediation (net 
of insurance recoveries). The Company 
also maintained a very tight discipline on 
capital management, ending the year 
with a strong balance sheet and liquidity 
of approximately US$1.5 billion, after 
repaying PNG LNG project finance debt, 
paying dividends, completing the Alaska 
North Slope acquisition and investing 
in an active exploration and appraisal 
programme in both PNG and Alaska.

OPERATIONAL AND 
PROCESS SAFETY

The safety of our people and 
contractors is paramount in everything 
we do as a Company. In 2018, the Total 
Recordable Incident Rate per million 
work hours fell from 1.93 in 2017, to 1.58 
in 2018. While we continue to strive for 

17

zero injuries, the downward trend in 
TRIR was a pleasing result, particularly 
considering the devastating Highlands 
earthquake. While the production 
facilities withstood the tremors well 
and there was no loss of hydrocarbon 
containment at any of our operated 
facilities or at the PNG LNG Project, 
lessons learnt from the impact of the 
earthquake on our camps and other 
infrastructure are now being built into 
our reconstruction efforts. 

Our Lost Time Injury Frequency Rate per 
million work hours and process safety 
events performance improved, despite 
the earthquake and recovery efforts 
and many challenging work activities 
conducted during the year. This 
included two extensive heli-supported 
seismic acquisition programmes, drilling 
at Muruk 2 at an altitude of 2,331 metres 
and the commencement of Alaskan ice 
road construction. 

Disappointingly, the Company’s High 
Potential (HiPo) incident frequency rate 
(events with the potential to result in 
serious injury or fatal consequences) 
rose from 0.68 in 2017 to 1.11 in 2018. 
Detailed investigation and analysis 
took place into all these incidents 
and associated corrective action 
and prevention programmes were 
developed, with workshops on safety 
leadership, planning, risk management 
and HSE management of contractors 
planned for 2019.

STRONG GROWTH IN RESERVES 
AND RESOURCES POSITION

A highlight for the year was the strong 
growth in the Company’s proved and 
probable reserves (2P) and contingent 
resources (2C), with 2P and 2C oil and 
condensate more than doubling, to 253.5 
mmbbl, and 2P and 2C gas increasing 
by 6.3%, to 6.7 tcf. The additions to 2C 
oil and gas reflected the booking of 
127.5 mmbbl of Alaska Pikka Unit oil for 
the first time and the successful P’nyang 
South 2 ST1 and Kimu 2 appraisal wells 
drilled during the year. Importantly, it is 
likely that a significant portion of the 2C 
resource increase will be converted to 
reserves over the next two years, as we 
proceed to final investment decisions on 
the development of three new LNG trains 
in PNG and the Pikka Unit. Oil Search’s 
strong resources position provides an 
excellent platform for these projects and 
supports our ability to provide top-tier 
long-term returns to our shareholders.

PAPUA LNG AND PNG LNG 
EXPANSION APPROACHING 
FEED ENTRY

As is the case with many large-scale, 
complex projects, bringing together 
all the strands of the proposed 
development of three new LNG trains 
in PNG has taken a little longer than we 
hoped and expected. However, steady 
progress was made during 2018 with 
the integrated development, which 
will result in a close to doubling of LNG 
capacity in PNG, expected to advance 
to the FEED phase in 2019.

Early in 2018, broad alignment was 
reached by Oil Search and its key joint 
venture partners on the preferred 
downstream development concept. 
This comprises the construction of 
three LNG trains with total capacity 
of approximately 8 MTPA located at, 
and integrated with, the existing PNG 
LNG plant. Two trains will be supplied 
by gas from the Elk-Antelope fields 
(Papua LNG) and one train will be 
underpinned initially by the PNG LNG 
Project fields and subsequently by the 
P’nyang field. All three trains will be 
operated by ExxonMobil, on behalf 

ExxonMobil’s Andrew Barry and Oil Search Managing Director Peter Botten signing the MOU, November 2018.

of the Papua LNG, PNG LNG and 
P’nyang joint ventures. Downstream 
pre-FEED technical work and upstream 
pre-FEED studies on the Elk-Antelope 
fields are both close to completion, 
while upstream work supporting the 
PNG LNG/P’nyang train, including the 
Associated Gas Expansion project, is 
also progressing well.

In November, a Memorandum of 
Understanding (MoU) was signed 
between the Papua LNG joint venture 
and the PNG Government at the 
Asia Pacific Economic Cooperation 
meetings held in Port Moresby. The 
MoU details fiscal arrangements and 
other key terms, including a Domestic 
Market Obligation, that will apply to 
the Papua LNG Project. This is now 
being translated into a fully-termed 
Gas Agreement, which is on track to 
be finalised by the end of March 2019. 
We believe that the terms agreed result 
in an equitable and appropriate split of 
Project value between the developers 
and the State. The P’nyang Gas 
Agreement is expected to be signed 
shortly thereafter. 

The conclusion of the Gas Agreements, 
together with commercial agreements 
supporting integration, including PNG 
LNG site and facilities access, will clear 
the way for an aligned FEED entry 
in 2019. 

In preparation for marketing our equity 
share of LNG from the Papua LNG 
Project, in early 2018 we established 
a highly experienced LNG marketing 
team based in Tokyo. Engagement with 

18

potential buyers has been encouraging, 
with positive feedback received from 
high quality LNG customers who are 
seeking source and seller diversification. 
The Papua LNG and PNG LNG/P’nyang 
joint ventures are targeting first LNG 
deliveries commencing in 2024, when 
significant additional supply will be 
required in Asia to meet both new 
demand and expiring contracts. Buyers 
are attracted by PNG LNG’s strong track 
record and reputation for the reliable 
supply of high heating value gas and 
our highly credentialed global LNG 
operators, as well as Oil Search’s ability 
to offer point-to-point LNG deliveries 
from PNG. 

EXPLORATION AND APPRAISAL 
IN PNG 

Despite some delays to the programme 
due to the Highlands earthquake, 
2018 was a year of high exploration 
and appraisal activity. During the 
year, we drilled two Forelands gas 
appraisal wells, both of which were 
successful, completed the P’nyang 
South 2 ST1 well in the Highlands, 
which resulted in a major upgrade in 
2C resources, and commenced drilling 
the Muruk 2 well, with positive early 
results. The gas resources discovered 
by these wells are expected to help 
underwrite the Company’s near and 
medium-term growth and provide field 
phasing optionality.

The Company also acquired 
approximately 380 kilometres of 
seismic data, one of the largest seismic 
programmes ever undertaken in PNG, 

and expanded its exploration portfolio 
through a farm-in to four prospective 
licences adjacent to Elk-Antelope. With 
an unrivalled acreage position in PNG, 
which the Company estimates to hold 
approximately 30 tcf of unrisked gas 
yet-to-be-found, we are well positioned 
to supply future LNG trains and provide 
high-value backfill gas.

PNG OIL FIELD OPPORTUNITIES 

In the PNG oil fields, we identified 
several attractive well and workover 
opportunities, primarily in Kutubu, 
Moran, Usano and the Agogo 
and Hedinia Forelimbs, which can 
potentially extend the oil production 
plateau until first gas is produced from 
LNG expansion. These opportunities, 
which will be progressively matured 
and implemented over the 2019-2024 
period, could add, in aggregate, 
approximately 30 mmbbl of highly 
value-accretive oil to Oil Search. The 
oil field optimisation programme has 
recently commenced with a workover in 
the Kutubu field, which will be followed 
by two workovers in Moran, with drilling 
at Moran and Usano planned for the 
second half of 2019.

MOMENTUM BUILDING IN ALASKA 

Since completing the acquisition of 
world class assets on the Alaska North 
Slope in February 2018, we have made 
substantial progress in unlocking 
value from the initial acquisition and 
positioning the Company for a long and 
successful future in Alaska. 

Over the year, we have built a highly 
experienced team in Anchorage, with 
currently more than 100 employees 
and several contractors, with diverse 
backgrounds in the global and local 
Alaskan oil industry, supporting the 
operations. Comprehensive planning 
for the 2018/19 drilling programme 
began in March, when we assumed 
operatorship of the assets. We 
secured two highly reliable rigs, built 
40 kilometres of ice-roads and three 
bridges, which were completed ahead 
of schedule, and commenced drilling 
the Pikka B well in late December, 

  O I L   S E A R C H   A N N U A L   R E P O R T  2 0 1 8

followed by the Pikka C well in January 
2019. We have been encouraged by 
the early results out of the appraisal 
campaign, with Pikka B intersecting the 
thickest Nanushuk reservoir section 
seen in the field to date. Both wells have 
been side-tracked and will be tested 
to establish flow rates, the volume, 
thickness and quality of the Nanushuk 
reservoir and to assist with the selection 
of the well design that will be used in 
the proposed Pikka Unit development. 
Positive results from these two wells 
could add up to 250 mmbbl to our 
current 500 mmbbl 2C gross resource.

Since arriving on the North Slope, we 
have leveraged our strong stakeholder 
engagement experience gained in PNG 
to build our Alaskan relationships and 
have had constructive discussions with 
the State, our joint venture partners, 
ConocoPhillips (the adjacent major 
operator in our region) and local 
indigenous populations. 

In November 2018, we received 
the Final Environmental Impact 
Statement for the proposed Pikka Unit 
Development and expect the Record of 
Decision in the first half of 2019. We are 
targeting FEED entry in 2019 and first 
production in 2023.

Everything we have seen on the 
Alaska North Slope to date has been 
encouraging. In early 2019, we built on 
our existing acreage position through 
the acquisition of interests in leases 
covering more than 215,000 gross 

acres, which have been identified as 
highly prospective for oil, underwriting 
our long-term growth in Alaska.

The optimisation of our interests, 
through the opportunity to exercise the 
Armstrong US$450 million option to 
double our interests in the key Alaskan 
assets and potentially divest part of the 
interest to a third party, is progressing 
well. We have had very constructive 
engagement with several interested 
parties regarding the opportunity and 
have been encouraged by the level 
and quality of interest in these world 
class assets.

COMMITMENT TO OPERATING  
IN A RESPONSIBLE WAY 

Maintaining a stable operating 
environment is critical to our long-term 
success in PNG and now also in Alaska.

One year after the 7.5 magnitude 
earthquake that devastated the PNG 
Highlands, Oil Search in partnership 
with the Oil Search Foundation, 
continues to provide long-term recovery 
assistance to impacted communities 
in the areas of infrastructure and public 
health. As already mentioned, Oil 
Search played a critical first responder 
role, offering its Moro logistical base as 
an important hub for aid distribution. 
The Company also contributed 
approximately US$5 million in cash and 
kind to support disaster relief efforts, 
in addition to generous contributions 
from our staff in both Australia and 

Substantial progress has been made in unlocking value from the Alaska acquisition and positioning  
Oil Search for a long and successful future.

process as an opportunity to consult 
with local communities, to better 
understand and ensure their comments 
related to culture, access, subsistence 
and environment were heard, respected 
and addressed. We continue to build 
relationships with all stakeholders on 
the North Slope, with the focus on 
securing stakeholder alignment on 
the forward exploration, appraisal and 
development programme.

CLIMATE CHANGE

In March 2018, Oil Search released its 
inaugural Climate Change Resilience 
Report in accordance with the Financial 
Stability Board’s Task Force on 
Climate-related Financial Disclosures. 
Comprehensive climate scenario 
analysis indicated that the Company’s 
current and growth assets in PNG and 
Alaska are resilient under a range of 
scenarios, including a 2°C pathway. The 
Report also demonstrated that there 
is a low risk of the Company’s assets 
being stranded in a carbon-constrained 
world. Pleasingly, our findings were 
confirmed in July 2018 by Carbon 
Tracker, which ranked Oil Search in the 
top quartile of 72 of the largest oil and 
gas companies globally for resilience 
to climate change risk. During the 
year, we also began a Physical Climate 
Change Scenario and Risk Assessment 
to understand and quantify direct and 
indirect physical risks of climate change 
on our assets, supply chains and project 
area communities. 

HUMAN RIGHTS

During the year, the Company 
commenced a comprehensive update 
of its Human Rights Impact Assessment 
in readiness for the introduction of the 
Modern Slavery Act in Australia and to 
include the Alaska business. In March 
2019, we will release a Preliminary 
Modern Slavery Statement providing an 
overview of our planned approach to 
contribute to global efforts to eliminate 
modern slavery.

PNG. The Company’s relief efforts were 
recognised through the receipt of the 
2018 Platts Global Energy Award for 
Corporate Social Responsibility and the 
PNG Chamber of Mines and Petroleum 
Outstanding Humanitarian Initiative 
Award at the end of 2018. 

During the year, we supported the Oil 
Search Foundation in its launch of Bel 
isi PNG, an innovative public-private 
partnership to address family and sexual 
violence in PNG. Bel isi PNG provides 
employees with case management 
and safe house services and provides 
business leaders with tools to 
support change in the workplace and 
community. We also developed new 
partnerships focused on engaging 
the PNG youth, particularly in the 
Highlands area, where more than 
50% of the total population is under 
20 years of age. Given our significant 
operational presence in the Highlands, 
engagement with young people in 
this area is a critical part of our future 
long-term success.

A 58 MW gas-fired power station, 
constructed by NiuPower Ltd, 
owned 50:50 by Oil Search and 
Kumul Petroleum, located next to the 
PNG LNG plant site, is expected to 
commence operations in March 2019. 
This power station, which will provide 
the lowest cost source of power and 
a much cleaner alternative to heavy 
oil and diesel, is expected to supply 
approximately 75% of the Port Moresby 

electricity grid. Our participation in 
power projects such as this is in line 
with the PNG Government’s strategic 
priority to deliver competitively 
priced power to more than 70% of the 
population by 2030.

We continue to support the PNG 
Government on the distribution of 
benefits owed to the PNG LNG Project 
landowner beneficiaries. During 2018, 
significant progress was made on 
resolving outstanding issues related 
to the identification and verification 
of beneficiaries.

In 2018, PNG hosted, for the first time, 
the Asia Pacific Economic Cooperation 
(APEC) meetings, which put the country 
on the world stage. The completion of 
APEC Haus, under the Government’s 
National Infrastructure Tax Credit 
Scheme, provided a world class 
conference venue for the APEC Economic 
Leaders’ Meeting, showcasing PNG’s 
unique culture to the world. Oil Search 
took an active role at the APEC Summit, 
addressing the region’s most influential 
leaders on how responsible investors can 
thrive by bringing communities along the 
development pathway. We believe the 
various APEC events and announcements 
during 2018 have provided a platform for 
a number of country changing initiatives.

OUTLOOK FOR 2019

In the 25 years that I have led Oil Search, 
I believe that our prospects to deliver 
superior returns to shareholders, in a 
socially responsible way, have never 
been better. The projects that are 
currently progressing will double our 
current production by the middle of the 
next decade. This is not production for 
production’s sake. These developments 
have the potential to provide attractive 
returns to shareholders in a responsible 
and moral way, meeting our social 
objectives in harmony with our climate 
management undertakings.

In January 2019, I was honoured to 
receive the Companion of the Order 

of Australia for service to Australia-
PNG relations, PNG business and 
community. I believe this award 
is for everyone at Oil Search. My 
longstanding belief has been that 
companies cannot operate in isolation 
from society if they are to generate 
goodwill, maintain a moral compass 
and create shared value between 
community and business. This belief is 
embedded within Oil Search’s vision 
and culture to generate top quartile 
returns for shareholders through 
excellence in socially responsible oil 
and gas exploration and production. I 
personally, and Oil Search corporately, 
remain as committed as ever to 
continuing to set the standard for 

private sector contributions to 
sustainable development and 
improving the lives of local communities 
where we operate. There is a 
compelling moral and business case 
to play an active role partnering with 
communities, Governments and 
other stakeholders for the social and 
economic development of the countries 
in which we work. We will continue to 
do this as part of our core  strategies.

Our key focus areas for 2019 include the following:

1.  Safety and environment. We will work on continuing to 
improve the Company’s focus on personal and process 
safety, reducing environmental incidents and targeting 
improvement across all metrics.

2.  Return to pre-earthquake production levels. Oil field 
activity will focus on returning the remaining facilities 
impacted by the earthquake to service, ensuring 
safe and reliable operations, maximising facility 
uptime and operational efficiency and optimising 
production through integrated reservoir, well and 
facility management. Strong performance by the 
PNG LNG Project, at rates averaging 8.5 MTPA, is 
expected to continue, excluding rate reductions for 
planned maintenance.

3.  Development of new LNG capacity in PNG. Following 
the signing of the MoU between the PRL 15 joint venture 
and PNG Government in November 2018, we aim 
to finalise the fully-termed PRL 15 Gas Agreement by 
the end of March 2019. The PRL 3 Gas Agreement for 
PNG LNG expansion is expected to be signed shortly 
thereafter, allowing an aligned FEED entry for the three-
train LNG development in 2019. 

4.  PNG oil field opportunities. In 2019, Oil Search plans 
to drill two wells and undertake three workovers as part 

21

of a multi-year in-field workover and drilling campaign 
to mitigate the decline from the mature oil fields.

5.  PNG exploration and appraisal activities. In the PNG 
Highlands, we plan to complete drilling and testing the 
Muruk 2 well, which will help delineate the potential 
gas resource volumes in the Muruk field. 

6.  Alaska North Slope. We will complete drilling and 

testing of the Pikka B and C appraisal wells, which could 
potentially result in up to 250 mmbbl of gross resource 
additions to the Pikka Unit, and move into FEED on the 
Pikka development. In addition, we will optimise the 
value of the Armstrong option.

7.  Stakeholder engagement. We will enhance 

stakeholder management in PNG and Alaska through 
ongoing communication and collaboration with key 
stakeholders, including our joint venture partners, the 
Government and local communities.

8.  Maintaining a stable operating environment. We will 
continue to implement social programmes, in PNG 
and in Alaska, that have a positive impact on the 
communities in which we operate.

In 2018, Oil Search delivered a 13% increase in net profit and a healthy US$855 million in 

operating cash flow, a solid result given the major PNG Highlands earthquake in February. 

At year end, the Company held liquidity of US$1.5 billion, after investing US$715 million in 

exploration and evaluation activities, including the US$415 million acquisition of petroleum 

interests on the Alaska North Slope. Together with ongoing strong operating cash flows, 

this liquidity position supports the Company’s financial capacity to fund its major growth 

projects in PNG and Alaska, as well as debt servicing and dividend payments over the 

period from 2019 to first production from those projects.

FINANCIAL PERFORMANCE 

Oil Search reported a 2018 net profit 
after tax of US341.2 million, 13% 
higher than the 2017 net profit of 
US$302.1 million.

The Company benefitted from stronger 
global energy prices, with the average 
realised oil and condensate price rising 
27% to US$70.65/bbl and the average 
realised LNG and gas price 31% higher, 
at US$10.06/mmBtu. This more than 
offset the 17% reduction in product 
sales volumes due to the earthquake, 
resulting in a 6% increase in total 
revenue, to US$1,535.8 million.

Production costs on a per barrel of oil 
equivalent (boe) basis increased from 
US$8.67 per boe in 2017, to US$11.52 
per boe in 2018. This reflected the 
Company’s largely fixed cost base 
spread over lower production, 
combined with earthquake recovery 
costs, net of insurance recoveries, and 
higher maintenance activities to take 
advantage of production facilities being 
shut-in post the earthquake. Other 
operating costs, including selling and 
distribution costs, royalties and levies, 
corporate and other expenses totalled 
US$145.4 million, broadly in line with 
the previous year.

Unit depreciation and amortisation 
charges increased 4% to US$12.40 
per boe, reflecting a larger proportion 
of higher unit rate amortisation from 
PNG LNG Project production in the 
Company’s product mix for the year.

The Company expensed US$66.7 
million of exploration costs in 2018, 
primarily related to seismic acquisition 
in PNG and Alaska as well as 
geological, geophysical and general 
and administration activities. Net 
finance charges totalled US$209.9 
million, 8% higher than 2017 levels, 
largely reflecting higher US interest 
rates that applied to the PNG LNG 
project financing.

The effective tax rate for 2018 was 
32.8%, compared with 31.5% in 
the prior year. 

CASH FLOWS

Despite lower production volumes 
resulting from the earthquake, the 
Company generated a healthy 
operating cash flow of US$854.6 
million, 1% higher than in 2017, buoyed 
by stronger realised oil and LNG prices.

Capital expenditure increased by 201% 
to US$835.4 million, predominantly 
driven by the expansion of the

of US$715 million. This included:

 š The acquisition of a high quality oil

 š The farm-in to exploration licences 
in the onshore Gulf of Papua.

 š Drilling/preparations to drill four

 š Pre-FEED activities for proposed 
LNG developments in PNG.

In addition, the Company commenced 
the implementation of a new group-
wide enterprise resource planning 
(ERP) system.

LIQUIDITY AND 
CAPITAL MANAGEMENT

While 2018 was one of the most 
challenging years in the Company’s 
history, Oil Search finished the year in a 
robust financial position, with liquidity 
of US$1.5 billion and only a modest 
increase in net debt.

The Company successfully refinanced 
and increased its committed bilateral 
corporate facilities from US$250 
million to US$300 million, with the 
expiry extended to December 2023. 
Together with the existing US$600 
million syndicated facility expiring in 
June 2022, the Company had US$900 
million in undrawn credit facilities and 
US$601 million in cash at year end.

Operating cash flow of US$855 million 
was used to repay US$322 million in 

PNG LNG project finance debt, fund 
US$114 million in dividends, complete 
the Alaska North Slope acquisition 
and invest in an active exploration 
and appraisal programme in PNG and 
Alaska. At the end of 2018, net debt 
totalled US$2.7 billion, only slightly 
above a year prior.

FUNDING FOR 
GROWTH PRIORITIES

Based on the Company’s oil price 
outlook, liquidity of US$1.5 billion 
and ongoing operating cash flows, 
Oil Search expects that it will have 
sufficient financial capacity to fund:

to reduce uncommitted exploration 
capital expenditure and/or reactivate 
the Company’s dividend reinvestment 
plan, which was introduced during 
the construction phase of the PNG 
LNG Project. 

While Oil Search remains comfortable 
with its liquidity and balance sheet 
position, it continues to closely 
monitor its funding capacity, including 
across a range of oil price and capital 
expenditure profiles, to ensure the 
Company will be able to fund its growth 
priorities and committed expenditures 
from operating cash flows, existing cash 
and debt facilities.

 š Scheduled debt repayments.

 š Future dividends in accordance with 
the Company’s dividend policy.

The Company also has a number 
of levers at its discretion, providing 
additional balance sheet flexibility 
should the oil price fall materially below 
current levels. These include the ability 

A 2018 final unfranked dividend of 8.5

the total unfranked dividend for 2018, 
including the 2.0 US cent per share

share. This represents a dividend payout 
ratio of 47%, at the upper end of the 
Company’s policy to pay out between 
35-50% of net profit after tax.

F O C U S   A R E A S

During 2019, Oil Search’s key financial objectives are as follows:

 š Finalise project financing approaches for Papua LNG 
and PNG LNG expansion with the Company’s joint 
venture partners and commence engagement with 
prospective lenders on the agreed financing plans. 

 š Develop a suitable financing plan for the development 

of the Pikka Unit in Alaska.

 š Continue to actively manage costs to maximise 

profitability and operating cash flows.

 š Drive value from the Company’s investment in a new 

ERP system.

P R O D U C T I O N

In 2018, Oil Search produced 25.2 million barrels of oil equivalent (mmboe). This compared 

to production of 30.3 mmboe in 2017, reflecting the shut-in of operated production 

and the PNG LNG Project following the 7.5 magnitude earthquake that struck the PNG 

Highlands in February 2018. The Company’s operating facilities and PNG LNG infrastructure 

withstood the earthquake well, with no loss of hydrocarbon containment. After coming 

back online in April, production from the PNG LNG Project recovered strongly, reaching 

an annualised production rate of 8.8 million tonnes per annum (MTPA) in the second half, 

the highest half year rate achieved since the Project came onstream in 2014. Production 

from the Company’s operated oil and gas assets has been progressively restored, with 

further improvements expected as remedial work continues through the first half of 

2019. Several development opportunities have also been identified in the Company’s 

operated oil fields in PNG with the potential to add 30 mmbbl to Oil Search, as well as slow 

the production decline from its mature oil fields.

PNG LNG PROJECT

PNG LNG Project production

The PNG LNG Project contributed 22.1 
mmboe net to Oil Search production in 
2018, comprising 19.1 mmboe of LNG 
and 3.0 mmboe of liquids (condensate 
and naphtha). 

Gross LNG production for the year was 
7.4 MT, only 11% below 2017, a strong 
result given the production shut-in 
following the earthquake in February. 
Production returned to pre-earthquake 
levels within a month of coming 
back online, reflecting the world-
class design and construction of the 
Project infrastructure, which enabled 
it to withstand the earthquake and the 
numerous aftershocks without any loss 
of oil or gas containment. 

During the period when operations 
were shut down, planned modifications 
to the Hides Gas Conditioning Plant and 
maintenance work on the LNG trains 
were brought forward. These activities, 
together with high operating reliability 
across all Project infrastructure, resulted 

in record production levels, with an 
average annualised rate of 8.8 MTPA 
achieved in the second half of 2018, 
almost 30% above nameplate capacity. 
Elevated production rates have 
been achieved with little additional

and local landowners. Sustainable 
production rates of 8.5 – 9.0 MTPA,

underpinned by the Project’s strong 
reserves position, which was upgraded

Solid demand for PNG LNG 
Project gas 

Since commencing LNG exports 
in 2014, the PNG LNG Project has 
established a reputation as a reliable 
exporter of high heating value LNG, 
a specification well suited to Asian 
gas reticulation networks. The Project 
also offers geographical diversity and 
shorter shipping turnaround times 
compared to other sources of LNG 
supply for Asian customers. This has 
resulted in strong demand for the 
Project’s uncommitted production, 
which has increased significantly since 
the Project commenced operations in 
2014, with 1.5 MT sold on a spot basis 
in 2018.

In 2018, the Project entered into two 
mid-term LNG sale and purchase 
agreements (SPAs) with PetroChina 
and BP, totalling 0.9 MTPA over five 
years from 2018 to 2023. These SPAs

add to the 6.6 MTPA committed under 
long-term contracts to JERA and Osaka 
Gas (Japan), Sinopec (China) and CPC 
(Taiwan), taking total contracted volumes 
to approximately 7.5 MTPA. ExxonMobil, 
on behalf of the PNG LNG Project 
participants, is continuing to negotiate 
the sale of a further mid-term tranche of 
0.45 MTPA. Oil Search believes the PNG 
LNG Project now has an appropriate 
mix of long-term contracts, mid-term 
contracts and sales on the spot market. 

Oil Search-operated PNG LNG 
Project activities

In 2018, the Oil Search-operated 
Associated Gas (Kutubu and Gobe Main) 
and SE Gobe fields delivered gas to the 
PNG LNG Project at an average rate of 
119.5 million standard cubic feet per day 
(mmscf/day), representing approximately 
12% of the total gas delivered to the 
LNG plant. 

The Oil Search-operated condensate 
handling facilities at the Central 
Processing Facility (CPF), liquids export 
pipeline and Kumul Marine Terminal 
handled 9.2 mmbbl (25,293 bbl/d) of 
condensate from the PNG LNG Project. 
Following the February earthquake, Oil 
Search prioritised the recommencement 
of gas supply from the oil fields and 
ensured that the integral parts of the 
Project infrastructure were ready to 
receive, store and export PNG LNG 
liquids ahead of the recommencement 
of gas production from the Hides Gas 
Conditioning Plant.

PNG LNG development activities

Construction of the pipeline and surface 
facilities to tie the Angore field into the 
PNG LNG processing facilities was 
temporarily halted in early 2018 due to 
political and inter-tribal issues. While 
tie-in work at the HGCP was completed, 
activities in the Angore field area remain 
suspended until community tensions 

27

in the area subside. The joint venture 
partners continue to encourage all 
parties to work together, to ensure issues 
are worked through in a peaceful and 
constructive manner.

PNG LNG Project benefits distribution 

In 2018, despite the interruption from 
the earthquake, the PNG Department 
of Petroleum focused on resuming the 
landowner identification process and 
made significant progress in completing 
phase one, involving the mapping, 
identification and vetting of various clans. 
Phase two will involve a process of ‘no-
objection’ to ensure landowners agree 
with the clan vetting process carried 
out in phase one. Once complete, the 
Government will work towards opening 
bank accounts so payments to vetted 
beneficiaries can be facilitated. Oil 
Search continues to provide support 
to the PNG LNG operator and the 
Government to complete this process. 

P R O D U C T I O N

PNG Power 

In 2018, NiuPower Ltd, which is 
owned 50:50 by Oil Search and 
Kumul Petroleum, commenced the 
construction of a 58 MW gas fired 
power station, capable of supplying 
approximately 75% of the average load 
of the Port Moresby electricity grid. 
The power station is located adjacent 
to the PNG LNG plant site, which will 
contribute 100% of the gas supply.

Construction of the power station was 
completed in February 2019, with 
commissioning activities currently 
underway ahead of first supply expected 
in March 2019. The power station aims 
to provide the lowest cost power in Port 
Moresby, with gas representing a cleaner 
fuel for power generation than other 
hydrocarbon sources such as heavy 
oil and diesel, significantly reducing 
environmentally harmful sulphur and 
greenhouse gas emissions.

PNG OPERATED OIL AND 
GAS PRODUCTION 

In 2018, Oil Search-operated 
production totalled 3.13 mmboe, 
produced at a gross average rate of 
8,589 boepd. This was 47% lower 
than in 2017, with the decline driven 
by the shut-in of operations due to 
the February earthquake. Production 
progressively ramped up over the 

balance of the year as remedial work 
took place and flow lines in remote 
locations were restored, enabling 
wells to be brought back online and 
production to be reinstated. This work 
is expected to be completed in the 
third quarter of 2019. Net crude oil 
production was 1.99 mmbbl, with the 
Kutubu and Moran fields together 
contributing 97% of total oil produced. 
The Hides Gas-to-Electricity Project 
contributed 0.87 mmboe while SE 
Gobe sales to the PNG LNG Project 
were 0.27 mmboe. 

Progressive recovery in production 
following February 2018 earthquake 

Production from the Kutubu complex 
oil fields declined by 38% during 
the year, reflecting the impact of the 
Highlands earthquake in February. 
Production recommenced in late March 
and rates continued to ramp up over 
the remainder of the year, as flow lines 
damaged during the earthquake were 
repaired and more wells brought online. 

Production from the Agogo and Moran 
fields resumed in the third quarter, 
though the amount of oil and gas 
that could be processed was limited 
by damage to the high-pressure 
compression systems at the Agogo 
Processing Facility, which were offline 
at the end of the year. The compression 

58 MW gas fired power station expected to supply approximately 75%  
of Port Moresby’s electricity needs.

28

systems were repaired and brought 
online in early February 2019.

Oil production from the Gobe Main 
and SE Gobe fields declined 26% 
and 38%, respectively. The Gobe oil 
fields returned to production in late 
April after earthquake repairs were 
completed and a planned shutdown 
for maintenance executed. At SE Gobe, 
oil and gas production rates remained 
impacted by damage to flow lines 
and key wells which remained offline 
due to the earthquake. The SE Gobe 
field contributed at a rate of 17 mmscf/
day (gross) to the PNG LNG Project 
during the year.

The Hides Gas-to-Electricity Project 
produced 4.0 bcf of gas and 83,000 
barrels of liquids, 32% and 29% lower, 
respectively, than 2017 levels.

Remedial work on the Company’s 
operated fields remains ongoing to 
reinstate production to pre-earthquake 
levels. This is expected to continue 
through the first half of 2019.

Associated Gas Expansion 
(AGX) opportunity

During 2018, work progressed on 
the Associated Gas Expansion (AGX) 
Project. The objective of the project 
is to increase the capacity of the Oil 
Search-operated CPF and APF to allow 
an acceleration in the volume of gas 
delivered from the Kutubu, Agogo 
and Moran fields to the PNG LNG 
Project. This represents a source of 
cost-effective gas that can front-end 
supply to the proposed new PNG LNG/
P’nyang LNG train for a number of years 
prior to developing the P’nyang field, 
optimising the capital spend profile. 
The project successfully passed through 
the concept screening phase, with work 
now taking place on the selection of the 
development concept. 

Numerous concepts were reviewed 
to assist in understanding the value 
of AGX to Oil Search and other 
stakeholders, with studies also taking 
place collaboratively with the PNG LNG 
operator on assessing the opportunity 
and how to manage risks. Several

studies were completed to increase 
the Company’s understanding of its 
operated fields and assets. In addition, 
engagement commenced with 
the Conservation and Environment 
Protection Authority and the 
Department of Petroleum regarding 
approval requirements.

The Company is aiming to reach 
agreement on the preferred 
development concept in the second 
quarter of 2019 to enable a decision 
on Front-End Engineering and Design 
entry in mid-2019. 

PNG oil field opportunities

During 2018, the Company carried out 
a major analysis on how to optimise 
production from its mature and declining 
oil fields in PNG. A range of new drilling 
and workover opportunities were 
identified for implementation over 
the 2019 to 2024 period, prior to first 
production from the next three LNG 
trains. Subject to final investment review 
and capital prioritisation, if successful, 
these opportunities have the potential to 
mitigate the production decline from the 
mature oil fields over the next five years 
and add approximately 30 million barrels 
to Oil Search’s oil reserves on a risked 
basis. The programme commenced with 
workover activity at Kutubu in the first

workover and drilling activity at Moran 
and further drilling at Kutubu later in 
the year. Additional opportunities are 
currently being assessed for technical 
and commercial feasibility and could 
contribute to drilling and workover 
schedules as early as 2020.

Process safety 

Process safety at Oil Search is focused 
on managing the hydrocarbon loss-of-
containment hazards that are associated 
with drilling and production activities. 
In 2018, the Company achieved a safe 
and sustainable return to service after 
the earthquake. This required the initial 
shut-in of all facilities, followed by 
detailed inspection, assessment and 
fit-for-service testing for wells, pipelines 
and production facilities before the 
assets were brought back online.

Despite the significant potential 
impact of the earthquake, no Tier 1 
process safety events (PSEs) occurred. 
There were three Tier 2 PSEs, none of 
which were related to the earthquake. 
During the year, the Company 
introduced measures such as third-party 
well control audits, process alarm 
management and training and 
competency assurance, to continually 
improve process safety-related 
systems and reduce risks related to 
major hazards.

Oil Search’s Total Recordable Incident 
Rate (TRIR) (recordable incidents per 
million hours worked) decreased by 18%, 
from 1.93 in 2017 to 1.58 in 2018.

While the Company strives for zero 
injuries, the downward trend was 
pleasing given the devastating February 
2018 PNG Highlands earthquake. Thanks 
to the consistent use of safety processes 
and procedures, the Company’s 
earthquake recovery and response was 
completed with zero recordable injuries.

G A S   D E V E L O P M E N T

During 2018, significant progress was made towards the development of additional LNG 

capacity in PNG, underpinned by gas resources from the Elk-Antelope fields (PRL 15) in 

the Onshore Gulf and the PNG LNG Project and P’nyang fields (PRL 3) in the North-West 

Highlands. Broad alignment was reached on the preferred downstream development 

concept, which comprises three trains with a total capacity of 8 MTPA, to be located at, and 

integrated with, the existing PNG LNG plant. Discussions on commercial arrangements to 

enable the integration of the Papua LNG Project (Elk-Antelope) with PNG LNG, pre-Front 

End and Engineering Design (FEED) downstream studies, upstream pre-FEED work on 

Elk-Antelope, project financing and LNG marketing also progressed. In November, 

a Memorandum of Understanding between the PNG Government and the PRL 15 joint 

venture was signed, outlining the key terms and conditions of the PRL 15 Gas Agreement. 

The Gas Agreement is targeted to be finalised by the end of March 2019, with a PRL 3 Gas 

Agreement expected to be completed shortly thereafter, allowing aligned FEED entry 

decisions to be made on the three LNG trains and the Papua upstream development in 2019.

MATERIAL PROGRESS MADE 
ON DEVELOPMENT OF NEW

LNG CAPACITY 

In early 2018, Oil Search and its joint 
venture partners, ExxonMobil and 
Total, reached broad alignment on 
the preferred downstream concept 
for the development of new LNG 
capacity. This followed the completion 
in late 2017 of engineering studies 
on potential development options to 
process the gas resources from the 
Elk-Antelope fields and P’nyang field. 

The proposed development concept 
comprises the construction of three 
LNG trains, with total capacity of 
approximately 8 MTPA, located on the 
existing PNG LNG plant site. Two of the 
trains will be dedicated to the Papua 
LNG Project, supplied with gas from 
the Elk-Antelope fields in PRL 15, and 
one train will be underpinned initially 
by gas from the existing PNG LNG 
Project fields and subsequently from the 
P’nyang field in PRL 3. This represents 
the most efficient means of expanding 

LNG capacity in PNG, providing for 
redundancy across trains, commercial 
flexibility and the incorporation of the 
latest technology. Significant capital 
and operating cost savings can be 
achieved from sharing infrastructure 
and construction synergies across both 
projects, benefiting all stakeholders.

CORAL SEA

During the year, the commercial 
arrangements supporting the 
downstream integration of the Papua 
LNG Project with the PNG LNG 
Project, including those related to 
site and facility access, were broadly 
agreed. Pre-FEED downstream studies, 
including engineering work on the 
design, process and layout optimisation 
of the three-train development, from 
the gas inlet to the LNG loading arm, 
continued in parallel. 

In addition, the Total-led PRL 15 joint 
venture undertook pre-FEED work 
on the upstream development of the 
Elk-Antelope fields. The upstream 
infrastructure for Papua LNG is 
expected to include:

PORT MORESBY

 š One Antelope well-pad, with up to 

seven wells. 

 š One Elk well-pad with one well. 

 š One produced water 
reinjection well.

 š Multiphase gathering system.

 š Central Processing Facility and 

related infrastructure, including acid 
gas removal unit.

 š Export pipelines (gas and 

condensate), comprising 60 
kilometres onshore and 260 
kilometres offshore.

The PNG LNG, PRL 15 and PRL 3 joint 
venture parties met regularly through 
the year to discuss contracting 
strategies, project financing and the 
remaining agreements required to 
enable integration of the projects. 

In the second quarter of 2018, the 
PNG Government established a State 
Negotiation Team (SNT) to negotiate 
gas agreements, including fiscal 
arrangements and other key terms and 

G A S   D E V E L O P M E N T

conditions, that will apply to the PRL 15 
and PRL 3 developments. In November, 
a Memorandum of Understanding 
(MoU) was signed between the PRL 15 
joint venture and the PNG Government, 
providing the framework for the PRL 15 
Gas Agreement and a timeline for the 
finalisation of negotiations. This was 
a major milestone for the Papua LNG 
Project, with all parties committed to 
concluding the PRL 15 Gas Agreement, 
which will include fiscal terms, a 
Domestic Market Obligation, National 
Content and other key terms, before the 
end of March 2019. 

Discussions also continued between 
the PRL 3 joint venture and the SNT. 
The PRL 3 (P’nyang) Gas Agreement is 
expected to be finalised shortly after 
the PRL 15 Gas Agreement, enabling 
aligned FEED entry decisions to be 
made on the proposed three train 
development to be taken shortly 
afterwards. The current timeline places 
the development on track to reach a 
Final Investment Decision in 2020 and 
first gas deliveries in 2024. 

In preparation for moving into the 
FEED phase, ExxonMobil is making 
preparations for FEED contracting for 
the downstream infrastructure, while 
the operator of Papua LNG, Total, is 
finalising the contracting strategy for 
the upstream facilities and pipeline to 
the PNG LNG plant site.

EQUITY MARKETING OF 
EXPANSION LNG 

In early 2018, Oil Search established 
a representative office in Tokyo, 
staffed with a highly experienced LNG 
team, to support its marketing team 
in selling its equity share of LNG from 
the Papua LNG Project. Engagement 
with potential LNG buyers in key Asian 
markets has been positive, supported 
by PNG’s established reputation as 
a reliable producer of high heating 
value LNG, and the experience of its 
global LNG operators, ExxonMobil 
and Total. Potential buyers have also 
been attracted by Oil Search’s unique 
offering, as a seller of point-to-point 
LNG from PNG, providing greater 
certainty of LNG specification.

RECERTIFICATION OF 
P’NYANG FIELD

In early 2018, an independent 
recertification of the P’nyang field’s 
resources was undertaken, incorporating 
the results of the successful P’nyang 
South 2 ST1 appraisal well, which 
proved up an extension to the south-
east, as well as additional seismic and 
core data. This resulted in the tripling of 
the certified gross 1C gas resource to 3.5 
tcf and an increase in 2C gas resource to 
4.4 tcf. This is very similar to Oil Search’s 
2C gas resource estimate of 4.5 tcf for 
the P’nyang field at the end of 2018.

Combined with gas resources in the 
Elk-Antelope fields in PRL 15, there

is approximately 11 tcf of certified

than sufficient to underpin the 8 
MTPA of proposed additional LNG 
capacity. Importantly, there is more 
than 8 tcf of 1C resource, which will 
greatly assist marketing activities within 
each venture. 

LNG MARKET OUTLOOK

In 2018, global LNG demand increased 
by 6% year-on-year, reaching a total 
of 320 MT. China accounted for more 
than half of global growth, reflecting 
the Chinese Government’s mandated 
switch from coal to gas-fired boilers, 
together with new import facilities. 
This resulted in a 41% increase in 
Chinese LNG demand, to 54.8 MT, 
making China the world’s second 
largest LNG importer after Japan, 
which imported 82 MT in 2018. South 
Korean imports increased 15% to 
44.5 MT due to nuclear outages and 
a similar Government directive to use 
gas instead of coal and nuclear energy. 
Indian imports also reached record 
levels as new contracts continued to 
ramp up, while neighbouring Pakistan’s 

GLOBAL LNG SUPPLY AND DEMAND

imports grew with the commissioning 
of a second Floating Storage and 
Regasification Unit (FSRU). 

Seven new liquefaction trains in 
Australia, Cameroon (FLNG), Russia 
and the United States commenced 
production in 2018. These, and other 
trains under construction, will ensure 
additional LNG supply is available 
through to the early 2020s, exceeding 
expected global demand. However, 
most industry experts forecast that 
there will be a material supply shortfall 
from 2022/23 onwards, with global 
LNG demand expected to grow at 
4.5% per annum over the period 
to 2030. This is driven by China’s 
continued move to displace coal with 
gas in the residential, commercial and 
industrial sectors to alleviate air quality 
issues and South Korea and Taiwan’s 
prioritisation of gas and renewable 
generation over coal and nuclear. 
Future demand will also be influenced 
by stricter emission standards leading 
to additional utilisation of gas in heavy 
trucking and marine transport, while the 
construction of gas pipelines, storage 
and regasification infrastructure across

China, India and other developing 
Asian nations will facilitate greater 
market penetration. 

Based on this strong demand growth 
outlook, as well as approximately 
65 MTPA of expiring contracts from 
Japan, South Korea and Taiwan out 
to the mid-2020s, it is estimated that 
approximately 120 MTPA of new LNG 
capacity will be required by 2030. In 
2018, 21 MTPA of new LNG capacity 
was sanctioned, more than double 2016 

Japan

and 2017 levels, and it is expected that 
significant additional capacity will be 
committed in the next few years to meet 
further demand growth. 

Commitment to LNG expansion 
in PNG is expected to be made in 
2020, with the sanctioning of three 
additional trains. With its high heating 
value gas, globally competitive cost 
base and geographic proximity to key 
Asian markets, Oil Search believes 
that new LNG supply from PNG is well 

South Korea

positioned. While not all of the many 
competing LNG projects proposed will 
progress, Oil Search, its joint venture 
partners and the PNG Government 
remain focused on developing

Oil Search was the most active explorer in PNG in 2018. During the year,  

the Company undertook drilling operations on four appraisal wells in PNG, two in the 

Forelands region in Oil Search-operated licences and two on behalf of ExxonMobil in the 

North-West Highlands. The Company also farmed into four highly prospective licences in 

the Onshore Gulf and completed one of the largest onshore helicopter-supported seismic 

programmes in PNG in its history. With an unrivalled acreage position in PNG, which Oil Search 

estimates to hold 30 trillion cubic feet (tcf) of unrisked gas yet-to-be found, the Company’s 

exploration strategy remains focused on gamechanger prospects in PNG’s key gas hubs and 

maximising joint venture alignment to optimise further LNG development in PNG.

PNG EXPLORATION 
PORTFOLIO UPDATE

Since 2016, Oil Search has significantly 
expanded its acreage position in PNG, 
focusing on four key areas – the North-
West Highlands, Onshore Gulf/
Forelands, Shallow Water Offshore 
Gulf and Deepwater Offshore Gulf - 
which the Company believes are the 
most prospective for hydrocarbons, 
particularly gas. Oil Search 
estimates that its current acreage 
holds approximately 30 tcf of gross 
unrisked gas yet to be found. 

Most of the prospects and leads are 
contained in reservoirs and traps that 
are already proven hydrocarbon plays 
and are located close to existing or 
planned infrastructure, increasing 
the likelihood that a discovery will be 
commercially viable. The majority are 
also in acreage held by Oil Search 
and its LNG joint venture partners, 

ensuring greater alignment on future 
development decisions. Several multi-tcf 
prospects that potentially could support 
an additional LNG train have been 
identified in the Company’s acreage. 
Given the requirement for gas to backfill 
existing and planned LNG capacity, even 
modest discoveries, of less than 500 
bcf, could be commercially attractive 
developments and could be used to 
optimise the sequence of gas field 
development in PNG.

While PNG is largely a gas province, 
there is also oil potential, primarily 
in areas adjacent to the existing oil 
fields operated by Oil Search, where 
even small volumes are likely to be 
commercial. Some of the large gas 
features also may contain material 
volumes of condensate.

During 2018, Oil Search, together 
with its joint venture partners, worked 
on maturing and de-risking its

on developing a long-term evaluation 
and drilling programme. Based on 
the current exploration portfolio, Oil 
Search plans to drill approximately 
two exploration and/or appraisal 
wells per year over the next five years, 
commencing in the second half of 2019, 
to support the Company’s long-term 
growth objectives.

Muruk 2, located 2,331 metres (7,648 feet) above sea level in the NW Highlands of PNG, commenced drilling in November 2018.

EXPLORATION ACTIVITIES 

North-West (NW) Highlands

During the year, preparations to 
drill the Muruk 2 appraisal well in 
PDL 9 (Oil Search – 24.4%), which 
were temporarily interrupted by the 
Highlands earthquake, were completed 
and drilling commenced in November 
2018 by Oil Search, on behalf of 
the operator, ExxonMobil.

The well penetrated the target Toro 
reservoir in January 2019. A number 
of cores were cut in the reservoir and 
the well was subsequently deepened. 
An extensive logging programme 
was conducted which confirmed the 
presence of hydrocarbons. The forward 
plan is to conduct an extended well test 
over the Toro reservoir interval.

Located approximately 11 kilometres 
north-west of the Muruk 1 gas discovery 
well, the Muruk 2 results will help 
constrain the potential resource volumes 

in the field by defining the extent of the 
gas bearing structure and determining 
the gas:water contact. Given its 
proximity to existing infrastructure at 
Hides, with the nearest producing well 
only 20 kilometres away, Muruk could 
provide a valuable source of gas either 
for an additional LNG train or as backfill 
gas for the PNG LNG Project. 

A 2D seismic programme covering 
approximately 100 kilometres over 
Muruk and an adjacent prospect, 
which was interrupted by the 2018 
earthquake, is being planned for 
acquisition in late 2019/early 2020. This 
will supplement seismic data acquired 
in this region in 2017 and help mature 
prospects identified along the Hides-
P’nyang trend for potential future 
drilling. Due to the proximity of these 
prospects to existing and planned 
infrastructure, they offer optionality for 
sourcing gas to support the PNG LNG 
Project or further LNG development. 

40

As discussed on page 36, the P’nyang 
South 2 ST1 appraisal well in PRL 3 (Oil 
Search – 38.5%) was also drilled by 
Oil Search, on behalf of the operator, 
ExxonMobil, and reached total depth 
in early January 2018. The well, which 
encountered gas in good-quality Toro 
and Digimu sands, confirmed the 
extension of the P’nyang field to the 
south-east. A recertification of the field’s 
gas resources by Netherland, Sewell 
& Associates, Inc. (NSAI) took place 
in early 2018, utilising results from this 
well and other new data, resulting in 
a material increase in NSAI estimates 
for both 1C and 2C gross resources, 
to 3.5 tcf and 4.4 tcf, respectively. The 
newly certified 2C resource estimate is 
similar to Oil Search’s gross 2C resource 
estimate of 4.5 tcf (see Reserves and 
Resources section on pages 62-69 for 
further detail).

GULF AND FORELANDS 

In 2018, significant exploration and 
appraisal activity took place in the 
Gulf and Forelands regions of PNG. 
These areas were not impacted by 
the earthquake and activity continued 
without interruption.

In the Forelands, the Company drilled 
two appraisal wells, Kimu 2 in PRL 8 
(Oil Search – 60.7%, operator) and 
Barikewa 3 in PRL 9 (Oil Search – 45.1%, 
operator). Both wells successfully 
intersected gas in their target reservoirs, 
with excellent reservoir quality 
observed. Following the successful 
Kimu 2 appraisal well, an additional 
186.7 bcf (net) of 2C gas has been 
assigned to the Kimu field. Evaluation 
of the data from both wells, including 
cores, logs and well test data and an 
update on the subsurface interpretation 
continues and is expected to be 
completed in early 2019. This will assist 

in delineating the resource base of 
these fields and the optimal route for 
potential commercialisation.

the field could be tied into existing 
infrastructure and assist with extending 
field life.

In the Onshore Gulf, the Company 
completed the acquisition of a 25% 
interest in four highly prospective 
licences, PPLs 474, 475 and 476 and PRL 
39, located adjacent to the Elk-Antelope 
fields in PRL 15 (Oil Search – 22.835%) 
from ExxonMobil. The acquisition has 
enhanced the Company’s exploration 
acreage in PNG and increased joint 
venture alignment in the highly 
prospective Onshore Gulf hub.

The Company is also evaluating 
drilling a well into the Gobe Footwall, 
commencing in the second half of 2019. 
The prospect, over which seismic was 
successfully acquired in late 2018, is 
immediately west of the Gobe Main 
field and can be drilled from an existing 
Gobe pad. In the event of success, 

OFFSHORE PAPUAN GULF

Following encouraging results in 2017 
from the reprocessing of existing 3D 
seismic data over the Shallow Water 
Gulf licences, in 2018, Oil Search 
completed further seismic reprocessing 
to establish the acreage’s prospectivity. 
The Company also completed the 
acquisition of a gravity gradiometry 
and magnetics survey over these 
licences. Together, this information 
will help identify targets for potential 
future drilling. 

Studies also took place on the Uramu 
discovery in PRL 10 (Oil Search – 100%, 
operator) in the Shallow Water Offshore 
Gulf, to ascertain its viability for 
appraisal drilling.

In the Deepwater Gulf, evaluation 
of 2D seismic data continued and 
identified prospects were risked, 
ranked and prioritised. Acquisition of 
3D seismic is planned in early 2020 to 
mature prospects further, subject to 
joint venture approval. As a result of 
this assessment, the Company farmed 
into an additional deepwater block, 
PPL 569, operated by ExxonMobil 
during the year.

Oil Search believes there are material and 
potentially multi-tcf gas structures in the 
Offshore Papuan Gulf. Given its proximity 
to infrastructure, any discoveries could be 
tied into the existing PNG LNG plant site 
for development.

SEISMIC DATA ACQUISITION 

In 2018, Oil Search successfully 
acquired approximately 380 
kilometres of 2D seismic over the 
Onshore Gulf and Forelands regions 
of PNG, one of the largest onshore 
helicopter-supported seismic 
programmes in PNG in the Company’s 
history. 

In the Onshore Gulf, the Company 
completed the first phase of a 2D 
seismic programme, comprising 330 
kilometres over PPLs 474 and 475 
and PRL 39 on behalf of the operator, 
ExxonMobil, and over Total-operated 
PRL 15. Based on positive results from 
preliminary processing of this data, in 

late 2018, the Company commenced 
a second phase, comprising 
approximately a 250-kilometre seismic 
programme which is expected to 
complete by mid-2019. Data from these 
surveys will help to mature identified 
leads and prospects located near 
planned Papua LNG infrastructure for 
potential future drilling.

A 50-kilometre seismic programme over 
PDL 4 and PRL 14 was also completed 
in the Forelands. Seismic data will help 
the Company assess the potential of the 
Gobe Footwall exploration prospect 
for potential drilling in the second half 
of 2019 and further constrain the Iehi 
gas discovery.

In February 2018, Oil Search completed the acquisition of world class oil assets in Alaska. 

The Company is using the knowledge, skills and experience gained in PNG, including how it 

operates in remote and challenging regions and its cooperative and collaborative approach 

to stakeholder engagement, to add value to its operations in Alaska. Over the course of 

the year, significant progress was made to advance this strategic addition to the Oil Search 

portfolio. The Company commenced a two-well appraisal drilling programme in the Pikka 

Unit within the Nanushuk oil play, the results of which will help finalise the scope of the Pikka 

Unit development. In addition, a world class team based in Anchorage was recruited, 

with the experience and capacity to lead the development of the Pikka Unit and maximise 

value from the Alaska business. Over the year, the Company built strong relationships with 

its partners, local communities and governments and materially expanded its acreage 

position. Preparations also advanced for the potential exercise of Oil Search’s option to 

increase its ownership interests in the Alaskan assets and undertake a partial divestment, 

to optimise the Company’s interests.

ENTRY INTO AN ESTABLISHED OIL 
PROVINCE, WITH SIGNIFICANT 
RESOURCE UPSIDE 

In February 2018, Oil Search’s US$400 
million acquisition of interests on the 
Alaska North Slope was approved by 
the Committee on Foreign Investment 
in the US and the purchase was 
completed. The Company assumed 
operatorship of the assets in March 
2018. This marked the Company’s 
entry into a well-established, prolific 
oil province, positioning Oil Search at 
the forefront of the development of the 
Nanushuk play in the Pikka Unit, one of 
the largest conventional oil discoveries 
in the US in more than 30 years.

Assets acquired include a 25.5% 
interest in the Pikka Unit and adjacent 
exploration acreage and a 37.5% 
interest in the Horseshoe Block, as well 
as a 25.5% interest in other exploration 

acreage. The acquisition also included 
an option, exercisable at Oil Search’s 
discretion until 30 June 2019, to 
double its interest in these assets for 
US$450 million. 

The Alaska acquisition was made based 
on an estimated gross resource of 
approximately 500 million barrels in the 
Nanushuk oil play and neighbouring 
reservoirs associated with the Pikka 
Unit. Additional upside potential has 
been identified in the continuation of 
the Nanushuk play into the Horseshoe 
block to the south of the Pikka Unit. 
Oil Search’s joint venture partners, 
Armstrong Energy and Repsol, estimate 
that ultimate recoverable volumes 
could be more than one billion barrels. 
Some of this upside will be tested in the 
2018/19 appraisal drilling programme, 
which, if successful, could add up to 
250 mmbbl (gross) to 2C resources.

Oil Search’s Alaska North Slope 
acquisition reflects the Company’s 
strategy to pursue, in a disciplined 
and measured way, material high-
returning liquids opportunities. 
The assets complement the Company’s 
existing high-quality PNG gas assets, 
creating a more balanced portfolio 
that is less exposed to one commodity 
and one country. 

With significant growth opportunities, 
the Alaskan assets have the potential to 
become, over time, a material business 
for Oil Search, of a similar scale to 
the Company’s PNG operations.

STAKEHOLDER ENGAGEMENT 

During 2018, significant engagement 
took place with local community groups 
and companies, other operators, the 
Federal and State governments and 
regulatory agencies. This was focused 
on building long-term relationships, 
developing a greater understanding 
of the major issues and opportunities 
in Alaska and maximising cooperation 
and alignment on the forward 
exploration, appraisal and development 
programme. As in PNG, Oil Search 
believes that ongoing, transparent, 
two-way communication is essential to 
delivering its long-term plans in Alaska. 
The Company is committed to ensuring 
local communities retain access to lands 
that promote subsistence lifestyles 

while operating safely and in an 
environmentally responsible manner.

The Pikka Unit boundary is located 11 
kilometres from Nuiqsut, a community 
of primarily Alaskan Native residents 
with a strong culture and a subsistence 
lifestyle. During the year, Oil Search 
worked closely with Nuiqsut and 
nearby Utqiagvik, as well as other 
Alaska North Slope communities and 
organisations, to identify opportunities 
for the Company to deliver its proposed 
Pikka Unit development in a mutually 
beneficial way that creates lasting value. 
Oil Search’s operations have already 
created direct and indirect jobs in the 
area and are having a positive effect on 
the local economy.

Oil Search has brought its cooperative and collaborative approach to  
stakeholder engagement to the Alaska North Slope.

Since acquiring the Alaskan assets, the 
Company has benefitted from a material 
uplift in value, driven by:

 š An increase in global oil prices (from 
mid-US$40/bbl in mid-2017 when 
the acquisition price was agreed).

 š The reduction in the US Federal

BUILDING CAPABILITY

Since assuming operatorship in March 
2018, the Company has built a highly 
experienced, multi-disciplinary team 
based in Anchorage. The group now 
comprises nearly 100 employees and 
several contract workers with extensive 
North Slope experience and outstanding 
subsurface, drilling, operations, 
development and commercial expertise 
in the global oil industry.

2018/19 APPRAISAL 
DRILLING PROGRAMME 

Extensive planning and preparations 
took place during the year for the 
2018/19 two-well appraisal programme 
on the Pikka Unit. The objective of the 
wells, Pikka B and Pikka C, which both 
comprise a vertical hole and a side-track 
allowing four reservoir penetrations, is to 
confirm the presence, volume, thickness 
and quality of the Nanushuk reservoir at 
the Pikka B and C locations. In addition, 
testing will confirm the oil quality and 
well deliverability, which will feed into 
the selection of the well design that will 
be used in the Pikka Unit development. 

In November 2018, construction of ice 
roads began, allowing the mobilisation 
of rigs to site. Drilling commenced on 
the Pikka B appraisal well, ahead of 
schedule, in late December. In early 
January 2019, the well penetrated 
the target Nanushuk formation and 
encountered hydrocarbons, in line 
with pre-drill expectations, and 146 
metres (480 feet) of cores were cut. 
Preliminary interpretation of cores has 
indicated a hydrocarbon-saturated, high 
porosity sand, with the thickest gross 
reservoir section ever intercepted in the 
Nanushuk. The well was subsequently 
side-tracked and drilled to a depth 
of 2,621 metres (8,600 feet) and an 
additional 91 metres (300 feet) of 
cores were acquired, which were also 
hydrocarbon-saturated. At the beginning 
of March 2019, the side-track was being 
tested to establish flow rates and gather 
other reservoir data at this location.

The Pikka C appraisal well commenced 
drilling in late January 2019 and reached 
a depth of 1,601 metres (5,253 feet), in 
the target Nanushuk Formation in late 
February. Reservoir data was acquired in 
the main hole and a horizontal side-track 
was subsequently kicked off. The 
side-track drilled a lateral section in the 
reservoir to a total depth of 2,772 metres 
(9,093 feet). The forward plan is to 
stimulate and flow-test the well. Results of 
Pikka C, which has been designed to be 
a development-type well, will assist in the 
selection of the well design to be used in 
the proposed Pikka Unit development.

feedback related to culture, access, 
subsistence and environment were 
heard, respected and addressed. In 
addition, significant analysis of potential 
environmental impacts and proposed 
avoidance and minimisation measures 
were incorporated into the design. 

ENVIRONMENTAL PERMITTING 
WELL ADVANCED 

In November 2018, the Final 
Environmental Impact Statement 
(FEIS) for the proposed Pikka Unit 
development was issued by the US 
Army Corps of Engineers (USACE). In 
the FEIS, the USACE recommended 
that the Pikka Unit be developed under 
the plan proposed by Oil Search. The 
FEIS, which took nearly four years to 
achieve, was a significant milestone for 
the project and followed consultation 

The proposed development concept 
also took into account the results from 
studies to optimise the development 
concept. This included cooperation 
with adjacent operators, reducing 
well numbers and therefore drilling 
costs by applying proven drilling 
and completions technologies, 
reviewing contracting strategies, 
reducing the project footprint and 
assessing the scope for early works. 
The Record of Decision is expected 
to be granted by the USACE late in 
the first quarter of 2019. 

Ice roads enable essential equipment and supplies, including drill rigs, to be mobilised to site during winter.  
The roads melt in spring, leaving minimal impact on the sensitive tundra.

PIKKA UNIT DEVELOPMENT

Initial concept select evaluations on 
the proposed Pikka Unit facilities 
took place during 2018. Subject to 
updated resource estimates based on 
the results of the Pikka B and C wells, 
the most likely development concept 
is a standalone 120,000 bopd central 
processing facility, with production 
from three drill sites. Wells will be 
drilled in producer/injector pairs. 
Further facility processing studies 
are currently underway to confirm 
the optimal configuration.

FEED entry is targeted for mid-2019 
and a final investment decision is 
expected to take place in 2020. 
Construction of the initial Pikka Unit 
development is planned to commence 
in early 2020 and take place over three 
winter construction seasons, with first 
production expected in late 2023.

EXPANSION OF 
ACREAGE POSITION 

Through the 2018 Alaska lease round, 
Oil Search acquired interests in, and 
became operator of, leases covering 
more than 17,000 acres east of the Pikka 
Unit through pre-existing commercial 
agreements with Repsol. The Company 
was also successful in directly 
acquiring leases covering 3,575 acres 
immediately adjacent to the northern 
boundary of the Pikka Unit.

In addition, in early 2019, through an 
arrangement with Armstrong Energy, 
the Company acquired a 50% interest in, 
and operatorship of, 120 leases covering 
approximately 195,200 gross acres in the 
eastern area of the Alaska North Slope. 
This area was identified in a regional 
study, conducted jointly by Oil Search 
and Armstrong Energy Corporation 
in 2018, as being highly prospective 
for oil within two separate plays. The 
leases cover the entire prospective trend 
identified by the study. 

These new leases add to the Company’s 
exploration prospect inventory and 
are part of the Company’s measured 
growth strategy, targeting high quality, 
highly prospective, material value

the Company for a long-term future 
in Alaska.

POTENTIAL OPTION EXERCISE 
AND DIVESTMENT

During the year, Oil Search continued 
to prepare for the potential exercise of 
the US$450 million option to double 

its interests in the Pikka Unit and 
Horseshoe Block and then to undertake 
a partial sell-down to a potential partner 
or partners through a competitive sale 
process. The Company has received 
multiple unsolicited inquiries from 
well-respected oil industry participants, 
demonstrating strong interest 
in these assets. 

The potential option exercise and 
divestment process provides an

Dr Graham Low from the Oil Search Foundation attending to a mother who has just given birth at the Hela Provincial Hospital in Tari.

In Hela Province, the OSF continued 
to support Hela Provincial Hospital 
by providing medical equipment 
and funding for doctors as well 
as management functions. The 
Hospital is now one of the three 
highest-performing health facilities 
in PNG. In a remote part of Southern 
Highlands Province, a new waiting 
house was also built, providing 
accommodation and facilities for a 
greater number of women to have 
supervised deliveries. In Gulf Province, 
OSF worked with the Southern 
Highlands and Gulf Province health 
teams to improve diagnostics for TB, 
with the aim of increasing treatment 
completion rates targeted at reducing 
the risk of drug-resistant TB and the 
number of resulting deaths.

In May, OSF partnered with the 
Australian Department of Foreign Affairs 
and Trade, the PNG Government and 
other donors on Wok Bung Wantaim 
(“Working in Partnership”). This initiative 
aims to improve health funding, 
planning and service delivery in Hela 
and Southern Highlands Provinces.

By working closely with local and 
District partners and Provincial 

Health Authorities, OSF continued to 
facilitate extended outreach patrols 
and mobile health clinics for some 
of PNG’s remotest areas, providing 
access to services for approximately 
65,000 people. More than 366,700 
vaccinations were delivered by 1,930 
OSF-supported outreach patrols 
and clinics and a total of 250 people 
completed TB treatment courses, a 27% 
increase on 2017. 

Education and leadership

Improving literacy and access to quality 
education is a sustainable development 
priority for the PNG Government and 
Oil Search. Working with OSF, the 
Company delivers programmes in areas 
around its operations that improve 
education and literacy outcomes. 

During the year, work began to rebuild 
two OSF literacy libraries in Tari that 
were significantly damaged by the 
earthquake and subsequent tribal 
fighting. These two libraries, plus a new 
library in Kikori, are due for completion 
in 2019. The Foundation also funded 
an induction course for librarians to 
increase the capacity for teaching basic 
early childhood literacy skills. 

52

OSF’s new scholarship programme, 
which will contribute to the 
development of effective and ethical 
PNG leaders, was launched in 2018. 
The programme helped 14 students 
successfully complete their academic 
year in medicine, nursing and business 
studies. In addition, 105 students were 
sponsored to attend tertiary institutions 
and 13 teachers upgraded their primary 
education qualifications from certificate 
to diploma level. 

Enterprise development

Focusing on local content creates jobs, 
promotes enterprise development and 
accelerates the transfer of skills and 
technologies. During 2018, Oil Search 
progressed the development of a local 
business strategy that aims to maximise 
the value and opportunities for local 
suppliers in Alaska. These include 
investing in supplier development, 
procuring supplies and services locally 
and hiring and training local workers.

Infrastructure

In 2018, Oil Search contributed to 
socio-economic development in 
PNG through the PNG Government’s 
Infrastructure Tax Credit Scheme 

(ITCS) and National Infrastructure Tax 
Credit Scheme (NITCS), supporting 
hospital and school upgrades and 
national projects. Unfortunately, project 
delivery timelines were impacted 
by the devastating earthquake, 
community unrest and local clan 
disputes. Some projects were also put 
on hold pending the formal findings 
of the PNG Government’s review of 
ITCS legislation, to which Oil Search 
made submissions.

As part of the NITCS, Oil Search project 
managed and delivered APEC Haus, a 
world class venue for the APEC Summit, 
which was hosted by PNG in 2018. 
Following the completion of APEC, 
the building has been designated to 
become a museum and conference 
centre that highlights PNG culture.

With access to power still a significant 
developmental issue, the PNG Biomass 
project advanced during the year, 
including obtaining an environmental 
permit. NiuPower, a joint venture 
owned by Oil Search and Kumul, also 
progressed construction of the 58 MW 
gas-fired Port Moresby power station. 
Located adjacent to the PNG LNG 
plant site, the power station will have 
the capacity to deliver approximately 
75% of the average daily load of the 
Port Moresby grid and is expected 
to produce the cheapest power in 
Port Moresby. 

Women’s empowerment

Oil Search works collaboratively 
with OSF to implement women’s 
protection and empowerment 
initiatives. In September 2018, OSF 
and its partners launched Bel isi PNG 
(“Peaceful PNG” in Pidgin), which uses 
an innovative multi-sector model to 
provide case management services and 
emergency accommodation for people 
experiencing family and/or sexual 
violence (FSV). The initiative brings 
together businesses, the Australian and 
PNG governments, service providers, 
local and international non-government 
organisations and technical advisors. 
Participating companies are able to 
help staff who need support such as 

  O I L   S E A R C H   A N N U A L   R E P O R T  2 0 1 8

medical care, counselling, police, legal 
resources and shelter. 

Women’s empowerment and 
protection was also the focus of the 
Champions of Change initiative, which 
was launched in 2018. Developed 
and driven by OSF, the programme 
encourages Oil Search employees to 
use the skills and knowledge gained 
at work to improve their communities. 
In 2018, 18 small grants were awarded 
through the Champions of Change 
initiative to support community 
activities, including training employees 
to address local FSV. 

CLIMATE CHANGE 

Community resilience

Oil Search’s PNG host communities 
can be vulnerable to natural disasters or 
incremental changes caused by climate 
change. By improving their resilience 

and contributing to natural disaster 
management, the Company has the 
ability to make a significant difference. 

In November 2018, Oil Search 
and PNG’s Climate Change and 
Development Authority (CCDA) 
established CCDA’s first public-private 
partnership (PPP) on climate resilience. 
Cooperation through this PPP will 
explore areas of mutual interest that 
contribute to the resilience of PNG 
communities, share and leverage 
knowledge and contribute to PNG’s 
National Determined Contributions 
adaptation targets. 

Physical climate change 
risk assessment

In 2018, Oil Search began a three-phase 
Physical Climate Change Scenario and 
Risk Assessment (PSRA) to understand 
and quantify direct and indirect 
physical risks of climate change on its 

Oil Search Foundation Director, Stephanie Copus-Campbell, with children enrolled  
in the Habare Literacy Library in Hela Province.

assets, supply chains and project area 
communities. The Company focused 
on implementing Phase 1 and will input 
the assessment findings into Oil Search’s 
engineering, investment and asset 
development plans.

HUMAN RIGHTS

Respect for human rights and the 
desire to do no harm underpin Oil 
Search’s commitment to sustainable 
development and the Company’s 
approach to operating responsibly. 
They help to build mutual trust and 
respect within the Company’s local 
communities, are vital to maintaining its 
social licence to operate and provide 
a stable operating environment. 

To demonstrate the Company’s 
focus on its most salient human 
rights issues, Oil Search updated its 
organisation-wide Human Rights Impact 
Assessment. This due diligence work 
examines the human rights risks and 
impacts associated with each type of 
Company and supply chain activity, 
including those associated with the 
Company’s power business and public 
infrastructure work in PNG as well as 
current and planned Alaskan activities. 
This work is expected to be finalised in 
early 2019. 

The assessment highlighted risk 
factors and other considerations 
around the potential modern slavery 
risks in the Company’s operations and 
supply chain. The results will inform 
several concurrent initiatives including 
reviews of the Company’s grievance 
management system, development 
of human rights training, responsible 
supply chain management and 
readiness preparations for disclosures 
under the new Australian Modern 
Slavery Act.

In 2018, Oil Search engaged human 
rights specialists to help the Company 
review its community engagement and 
grievance management practices and 
update business requirements for the 
assessment, escalation, investigation 
and remedy of community grievances, 
as well as needs for resources, training

human rights plan. 

large part, from the non-payment of 
funds committed by the Government to 
the landowners.

BENEFITS DISTRIBUTION

As in previous years, Oil Search 
voluntarily disclosed its 2018 payments 
to governments in the Annual Report, 
the Transparency Report and the PNG 
Extractive Industries Transparency 
Initiative Report.

In PNG, ExxonMobil, on behalf of the 
Project participants, pays royalties from 
the PNG LNG Project into a trust fund 
administered by the PNG Government, 
which is responsible for distributing 
benefits payments to landowners. The 
landowner identification process is 
integral to determining the appropriate 
allocation and distribution of these 
benefits. This process has experienced 
delays due to landowner disputes and 
the February Highlands earthquake. In 
early 2018, Oil Search’s oil operations 
in one licence area were interrupted 
due to community unrest resulting, in 

During the year, the Department of 
Petroleum resumed the identification 
process and made significant progress 
in completing Phase 1 of the PNG 
LNG identification process. Phase 2 is 
anticipated to be completed in the first 
half of 2019.

LAYING FOUNDATIONS IN ALASKA

Following the assumption of 
operatorship of the Alaska assets in 
2018, Oil Search started to build the 
relationships and partnerships that will 
be so important to progress this project 
and maintain local community support. 

Community groups are a major 
engagement channel and the 
Company invested in many stakeholder 
engagement activities that were in 
addition to Oil Search’s regulatory 
obligations. This included hosting 
meetings and workshops close to the 

O I L   S E A R C H ’ S   C L I M AT E   E F FO R TS   R E CO G N I S E D

In March 2018, Oil Search published its inaugural Climate Change Resilience 
Report aligned with the recommendations of the Financial Stability Board’s 
Task Force on Climate-related Financial Disclosures (TCFD). The Report 
assessed the financial risks of climate change by examining the Company’s 
existing and future projects and their resilience in a range of decarbonisation 
scenarios, including a 2°C world. 

In July 2018, Carbon Tracker published its 2 Degrees of Separation 
report, which estimated the relative climate change transition risk of 
major oil and gas producers, from the point of view of potential capital 
expenditure committed to high-cost projects outside a 2°C pathway. 
The Report placed Oil Search in the top quartile for resilience to 
financial transition risk and found all of its projects would be required in 
both a 2°C pathway and a 1.75°C pathway.

Carbon Tracker’s assessment is consistent with Oil Search’s own analysis 
and demonstrates to shareholders, communities, employees and other 
stakeholders that the Company’s climate change risk processes are robust 
and its assets have long-term resilience and value-generation in a 2°C world.

share information and gather feedback, 
as well as appointing a community 
liaison person to engage with the local 
community. Oil Search also took part in

Through proactive, defined 
engagement, the Company aims to 
create the opportunity for dialogue, 
demonstrate its willingness to identify 
and understand suggestions and 
concerns and establish a positive 
reputation within the community.

progress was made in this area during 2018. Several initiatives are underway to continue 

to strengthen the Company’s pipeline of future leaders, foster employee engagement 

and build a capable and diverse workforce. The representation of females and PNG 

citizens in leadership roles increased and Oil Search was recognised in the Top 200 

of Equileap’s 2018 Gender Equality Ranking.

SUPPORTING DIVERSITY 
AND INCLUSION

Oil Search’s capability and resilience 
are strengthened by having a diverse 
and inclusive workforce. In 2018, 
the Company remained focused 
on improving diversity through 
its 2020 Diversity and Inclusion 
Strategy, which addresses gender 
diversity, citizen development and an 
inclusive workplace. 

The Board’s gender diversity was 
improved with the appointment of 
a new female director, increasing 
the percentage of female directors 
from 25% in 2017, to 33% in 2018. 
The percentage of females in senior 
management and the 2018 Graduate 
Development Programme intake 
also increased, to 23% and 46%, 
respectively in 2018. 

During the year, the Company 
delivered its inaugural Leading Our 
Way for Women leadership programme 
involving 17 participants across 
the organisation. This programme 
is designed to build a population 

of high potential female leaders 
and improve gender diversity in 
leadership roles within the business. 
Participants benefited from an intensive 
development experience, with their 
managers also involved to promote 
greater understanding and empathy 
for the various development barriers 
faced and how best to address these. 
Since commencing the programme, five 
participants have been promoted and 
another three have had the opportunity 
to change roles within the business.

As part of the Company’s 2020 
Diversity and Inclusion Strategy, Oil 
Search measures progress against an 
inclusion index derived from the results 
of its 2017 employee engagement 
survey. An organisation-wide employee 
engagement plan was implemented 
in 2018 to promote an inclusive and 
positive work environment. Initiatives 
focused on: 

 š Enabling managers to create a safe 
and trusting environment where 
people feel valued and can work to 
their potential.

 š Equipping managers to have 

engaging conversations and bring 
out the best in their staff through the 
Coaching Our Way programme. 

 š Recognition Guidelines that support 

more frequent and consistent 
manager recognition. 

Citizen Development 
Programme (CDP)

Established in 2016, the CDP provides 
clear development and employment 
opportunities for high performing 
PNG citizens.

In 2018, 70 participants, all of 
whom are supported by a coach 
and have individual development 
plans underway, attended the 
annual CDP residential workshop. 
Of these participants, 17 progressed 
into leadership roles and eight 
were provided with a secondment

Oil Search also partnered with the 
Oil Search Foundation to develop a 
scholarship programme focused on 
the early identification and attraction of 
technical and leadership talent amongst 
PNG citizens. The programme will 
provide educational opportunities at 
secondary and tertiary levels and will be 
implemented in 2019.

Oil Search continually reviews and 
refreshes its CDP in support of its 
commitment to local leadership and its 
2020 Diversity and Inclusion goals. 

BUILDING CAPABILITY

In 2018, employee development 
was a key focus, with several 
initiatives underway to develop 
workforce capability, foster employee 
engagement and manage the pipeline 
of people with the potential to move 
into leadership roles. These initiatives 
fit within an expanded leadership 
development framework that balances 
development for all employees 
with targeted investments to build 
leadership capacity and capability 
for the future.

Workforce capability 
and engagement

In 2018, Oil Search continued to 
expand its leadership development 
curriculum, with the introduction of 
Coaching Our Way. This programme 
equips leaders to create an engaging 
work environment and enhance the 
employee experience of recognition, 
development, learning and growth. 15 
Coaching Our Way workshops were 
held during the year for 161 senior 
managers, managers and supervisors in 
Sydney and Port Moresby.

The Company upgraded its 
performance and development process 
to enhance employee engagement 
through more constructive and frequent 
conversations and planning. The 
refreshed process will be introduced in 
2019 enabled by a new HR Information 
System and a comprehensive launch 
strategy that includes employee and 
leader workshops. 

Managing our leadership pipeline

The depth and diversity of leadership 
talent continues to improve across 
the organisation. This is managed and 
tracked through the Company’s annual 
talent and succession review which, 
in 2018, assessed 192 critical roles for 
succession with the following results: 

 š 86 employees were evaluated 

as being high potential (capable 
of progressing to leadership or 
executive levels).

 š 15 individuals were assessed as 

successor candidates to Executive 
General Manager roles.

 š 44% of individuals on succession 
plans were PNG citizens and 31% 
were female. 

Several programmes are in place to 
manage and continue to develop a 
diverse leadership pipeline across 
the organisation, including the 
following programmes:

 š Graduate Development Programme.

 š Accelerated Development 
Programme (for high 
potential employees).

In 2018, the Senior Leader Development 
Process was introduced to build a 
highly capable, committed and diverse 
leadership group that is well-equipped 
to execute Oil Search’s Business 
Strategy. Six participants were selected 
across Port Moresby, Sydney and 
Anchorage, with the programme to be 
extended across a broader population 
in 2019. The process includes a rigorous 
upfront assessment and individual 
development strategies deployed 
over 12 months ranging from executive 
education, to coaching, mentoring and 
involvement in business projects.

CODE OF CONDUCT

In 2018, Oil Search strengthened 
its Code of Conduct to include new 
guidance around personal relationships 
within the organisation. This reinforced 
the Company’s approach to managing 
conflicts of interest to ensure all 
decisions regarding a person’s work, 
entitlements or position/standing 
in Oil Search are made without bias 
or discrimination. 

During the year, Oil Search investigated 
all reported and suspected breaches of 
the Code of Conduct. After appropriate 
investigations, 11 records of discussion 
or written warnings were issued, 
one termination occurred and one 
employee resigned. The breaches 
related to harassment and bullying, 
policy or procedures and health, safety, 
environment and security. No instances 
of discrimination were reported.

One call was made to the Company’s 
Whistle-blower Hotline relating 
to a conflict of interest. The issue 
was investigated, found to be 
unsubstantiated and closed out via 
the whistle-blower process.

Oil Search is committed to protecting and improving the health and 
wellbeing of its employees and contractors. In 2018, the Company’s 
wellbeing programme was rebranded and reintroduced as “Lifestyle 
Connect”, a programme that builds on the existing platform to deliver a 
renewed focus on managing the impact of lifestyle diseases. The Lifestyle 
Connect programme includes education, health checks, occupational 
health and professional support for employees and their families. 

With awareness about mental health conditions increasing globally, 
Oil Search is acting to create a psychologically healthy workplace 
by helping to protect its workers’ mental health. During 2018, 
industry experts delivered Better Mental Health training to 691 
employees to help them recognise and manage mental health issues 
for themselves and their colleagues.

DEMONSTRATING A CULTURE OF 
SOCIAL RESPONSIBILITY

During 2018, Oil Search employees 
demonstrated a strong culture and 
commitment to social responsibility 
through a number of initiatives:

 š Employees were at the forefront of 
the earthquake relief and response 
campaign, donating more than 
US$19,500 in cash and coordinating 
the collection and delivery of 170 
boxes of goods and supplies from 
staff and partners. 

 š The Sydney Social Club raised 

almost US$4,500 for Bel isi PNG 
through a Christmas drive selling 
cards and wrapping paper based on 
drawings from children in the Kikori 
Literacy Library. 

 š Employees represented Oil Search 
at a 2,000-strong walk in Port 
Moresby in support of the 2018 
International Day for the Elimination 
of Violence Against Women.

 š Sydney and Port Moresby 

employees participated in Oil 
Search’s Caring for Kids Corporate 

Fitness Challenge, raising over 
US$17,400 for the Children’s Ward 
at Port Moresby General Hospital. 

 š Through the Daffodil Corporate 
Golf Challenge, the Company 
helped to raise US$30,000 to bring 
cancer education and awareness 
programmes to communities and 
schools throughout PNG. 

 š A total of 27 employees and 
contractors in Port Moresby 
participated in the corporate blood 
drive in support of the Port Moresby 
General Hospital Blood Bank.

Oil Search employees were involved in several social responsibility initiatives in 2018.

R E S E R V E S   A N D   R E S O U R C E S

In 2018, Oil Search’s total oil and gas proved and probable (2P) Reserves  

and contingent (2C) Resources increased by 15%. 2P and 2C Reserves  

and Resources are now at the highest level the Company has ever recorded.

  O I L   S E A R C H   A N N U A L   R E P O R T  2 0 1 8

Total 2P and 2C oil Reserves and 
Resources increased 102% to 253.5 
million barrels (mmbbl). This primarily 
reflected the booking of 127.5 mmbbl 
2C oil Resources at the Pikka Unit for 
the first time, following the completion 
of the Company’s acquisition of 
assets on the Alaska North Slope in 
February 2018. 

Total 2P and 2C gas Reserves and 
Resources rose by 6% to 6,742.2 billion 
cubic feet (bcf) due to additions at 
the P’nyang and Kimu fields in PNG 
following successful appraisal drilling 
during the year.

This strong resources position provides 
the platform for Oil Search’s growth 
projects in both PNG and Alaska and 
supports the Company’s ability to 
provide excellent long-term returns 
to shareholders.

Based on 2018 production of 25.2 
mmboe, Oil Search has a 1P Reserves 
life of 17 years and a 2P Reserves and 2C 
Resources life of 63 years.

OIL AND GAS RESERVES 

At 31 December 2018, the Company’s 
Proved (1P) Reserves were 54.1 mmbbl 
of oil and condensate and 1,937.1 bcf of 
gas. Proved and Probable (2P) Reserves 
were 68.0 mmbbl of oil and condensate 
and 2,209.3 bcf of gas.

The key changes in 1P and 2P Reserves 
since 31 December 2017, which 
are summarised in Tables 1 and 2, 
are as follows:

 š Reserves at 31 December 2018 have 
been adjusted for net production of 
4.9 mmbbl of oil and condensate 
and 98.9 bcf of gas1.

 š There have been no changes to the 

estimated ultimate recovery (EUR) for 
oil and gas associated with the PNG 
LNG Project, or oil in the Kutubu 
Agogo, and Moran fields. Reserves 
in both the 1P and 2P categories 
reflect the year-end 2017 position 

less 2018 production volumes.

 š There were minor additions 
to the Hides GTE 1P Reserve 
booking, reflecting the 2017 gas 
nominations under the Hides Gas 
Sales Agreement. 

 š There have been minor reductions 
to the Gobe Main oil booking 
and SE Gobe bookings for oil 
and gas. These are the result of 
revised Operator forecasts, which 
incorporate changes to production 
assumptions since the last external 
audit in 2015.

Developed and undeveloped Reserves 
are shown in Table 3. Undeveloped gas 
and condensate Reserves are related 
to the PNG LNG Project, where the 
construction of additional infrastructure 
is required prior to the commencement 
of gas export, consistent with the 
approved development plan. 
This infrastructure is not currently 
required, as the developments on-
line can provide sufficient gas to the 
LNG facilities.

Undeveloped oil Reserves are 
associated with future development 
drilling in producing oil fields.

CONTINGENT RESOURCES

At the end of 2018, the Company’s 
2C Contingent Resources comprised 
4,533.0 bcf of gas, up from 4,027.4 
bcf at the end of 2017, and 185.5 
mmbbl of oil and condensate, up from 
52.7 mmbbl.

The key changes in 2C Contingent 
Resources since 31 December 2017, 
which are summarised in Tables 1 and 2, 
are as follows:

 š The addition of 127.5 mmbbl 
of oil Resources in Oil Search’s 
Alaskan North Slope assets, after 
the acquisition of interests in the 
Pikka Unit.

 š The addition of 319.8 bcf gas and 

5.2 mmbbl condensate at P’nyang, 

1.  Note that these production figures are based on Oil Search’s net 16.67% share of PDL 1 Hides 

GTE production

63

after the successful drilling of the 
P’nyang South 2ST1 well (see below 
for further details).

 š The addition of 186.7 bcf 2C gas at 
Kimu, which reflects the Company’s 
successful Kimu 2 appraisal well 
drilled in 2018. 

 š Minor movements in Contingent 
Resources at Gobe Main and 
SE Gobe, associated with the 
production beyond economic 
life from the updated forecasts for 
these fields.

RESERVES AND RESOURCES

As highlighted in Table 4, at the 
end of 2018, Oil Search’s total 2P oil 
and condensate Reserves and 2C 
Contingent Resources were 253.5 
mmbbl, up from 125.8 mmbbl at 
year-end 2017. The Company’s total 
2P gas Reserves and 2C Contingent 
Resources were 6,742.2 bcf, up from 
6,341.1 bcf at the end of 2017.

PIKKA UNIT, ALASKA NORTH 
SLOPE – BOOKING OF 2C 
CONTINGENT RESOURCE

Following the completion of the 
acquisition of a 25.5% interest in the 
Pikka Unit in February 2018, 127.5 
mmbbl of oil net to Oil Search have 
been assigned to the 2C Contingent 
Resource category. This reflects Oil 
Search’s 25.5% share of the estimated 
gross resources for the Unit of 
500 mmbbl.

The current mapping of the Nanushuk 
and satellite reservoirs in the Pikka Unit 
is based on an extensive grid of 3D 
seismic data and 19 well penetrations.

The presence of significant quantities 
of moveable hydrocarbons in the 
Pikka Unit has been confirmed from 
the following:

 š Data acquired from well logging 

during and after drilling, which has 
been used to determine the fluid 

R E S E R V E S   A N D   R E S O U R C E S

The Kimu 2 appraisal well resulted in the addition of 186.7 bcf (net) of 2C gas resouce  
to Oil Search’s Kimu booking.

content and most likely fluid contacts 
in the sandstone reservoir. This 
approach includes the analysis of 
reservoir pressure data and samples 
of hydrocarbons brought to surface 
during wireline logging.

 š The interpretation of data acquired 
from six production tests (notably 
the Qugruk 301 horizontal well and 
the Qugruk 8 vertical well), including 
the analysis of reservoir hydrocarbon 
samples recovered to surface.

 š The interpretation of 3D seismic data 

and data from offset wells.

Oil Search has assessed all available 
data to reach a position on the 
Contingent Resource potential of the 
field. Contingent Resource volumes 
have been estimated by combining 
in-place volume estimates from 
geological modelling with recovery 
factor estimates from both reservoir 
simulation studies and analogue fields. 
A deterministic approach was used to 
estimate the reported volume.

These Resources are considered 
contingent on future appraisal results, 
development studies and project 
commerciality. The collection of 
additional well log, core and production 
test data is currently underway, with the 
drilling of two further appraisal wells 
with two penetrations each – Pikka B 
and C. The data from these wells will 

be evaluated during 2019 to assess 
the potential for commercial recovery 
and to further define the Company’s 
resource estimates for the field.

P’NYANG – INCREASE IN BOOKED 
2C CONTINGENT RESOURCE

The addition of 319.8 bcf of 2C gas and 
5.2 mmbbl of 2C condensate reflects 
the interpretation of data gathered from 
the drilling of the successful P’nyang 
South 2 ST1 appraisal well in 2018, as 
well as updates to the proposed field 
development plan.

The P’nyang Resource is considered to 
remain contingent on several factors, 
including: additional technical studies, 
the confirmation of a commercially 
viable development project, acceptable 
project financing and the negotiation 
of, and commitment to, future gas 
sales contracts.

KIMU – INCREASE IN BOOKED 2C 
CONTINGENT RESOURCE

An additional 186.7 bcf of 2C gas 
has been booked in the Kimu field, 
following the successful Kimu 2 
appraisal well. The increase in booked 
volume has been determined by 
analysis of the results of the May 2018 
drill-stem test, which produced gas 
from the Alene sandstone interval. 

64

The Kimu Resource is considered to 
remain contingent on multiple factors, 
including the requirement for additional 
technical studies, a commercially viable 
development project and future gas 
sales contracts.

BARIKEWA – NO CHANGE TO 
BOOKED 2C CONTINGENT 
RESOURCE

The Barikewa 3 well drilled in 2018 
successfully intersected hydrocarbons, 
in line with expectations. Initial 
analysis of the data collected with the 
well supports the existing Barikewa 
Resource booking. Further technical 
studies on Barikewa will be carried out 
through 2019 to review Resource size 
and assist in determining the optimal 
commercialisation options for this 
gas field. 

GOVERNANCE AND 2019 
AUDIT PLAN

The governance arrangements for the 
reporting of hydrocarbon Reserves and 
Resources are based on Oil Search’s 
Resources Management and Audit 
Process (RMAP), which consists of 
the following:

 š A Technical Reserves Committee 

(TRC), which assesses all proposed 
changes and additions to the 
Company’s Reserves and Resources 

database, utilising advice and 
contributions from peer review 
and subject matter experts, 
where appropriate.

 š The TRC reports to the Reserves 
Operating Committee (ROC), 
consisting of senior management 
from technical and commercial 
disciplines, for the sanction of 
changes proposed by the TRC.

 š Final statements are subject to 

review by the Audit and Financial 
Risk Committee prior to approval by 
the Board.

Oil Fields

Under the Company’s Reserves 
Management and Audit Process, 
operated oil fields are subject to 
independent audit every three years, 
or alternative intervals under some 
circumstances (for example, where 
anticipated changes may or may not 
be material). The Kutubu and Moran 
fields were audited at year-end 2017 
by independent auditor, Netherland, 
Sewell & Associates, Inc. (NSAI). No 
changes to the Kutubu and Moran 
fields’ EUR are anticipated after the 
2018 earthquake, due to the recovery 
programme implemented through 2018 
and 2019. As such, no further audit is 
planned for 2019.

The Gobe oil fields were audited in 
2015, also by NSAI. In 2018, an external 
audit was deferred, due to the low oil 
Reserves associated with these fields. 
The requirement for external audit of 
the Gobe oil fields will continue to 
be assessed under the Company’s 
Reserves Management and Audit 
Process in 2019.

PNG LNG Project

A PNG LNG Project Resources re-
certification is proposed for 2019, to 
provide an updated view of PNG LNG 
Resources to support the funding 
of the third LNG train and gas sales 
marketing. This work is intended to 
capture data gathered, including the 
significant improvements in production 
performance, since the last re-
certification was conducted in 2016. 

  O I L   S E A R C H   A N N U A L   R E P O R T  2 0 1 8

As with the 2016 re-certification, while 
the PNG LNG Operator will coordinate 
and manage the overall certification 
process, Oil Search will take a leading 
role in the re-certification of the 
Associated Gas (AG) field Reserves. 

PRL 15

Two separate audits of the Resources 
at Elk-Antelope were undertaken by 
NSAI and Gaffney, Cline & Associates 
(GCA) in 2016 as part of the First PAC 
Certification under the sale and 
purchase agreement with the sellers 
of the PAC LNG group of companies. 
These audits were updated by the same 
auditors in 2017 to include the results 
of Antelope 7 for Oil Search internal 
purposes. There is no requirement for 
further audit in 2019.

The Second PAC Certification will 
occur one year after delivery of the first 
commercial LNG cargo.

Muruk

An independent certification of the 
Muruk field may occur in 2019, subject 
to the results of the Muruk 2 well.

PRL 3

Gas Resources at P’nyang (PRL 3) were 
recertified by the Joint Venture in 2018 
following the drilling of the successful 
P’nyang South 2 ST1 appraisal well. No 
further audit is planned for 2019.

Other gas fields 

Following the successful Kimu 2 
and Barikewa 3 appraisal wells and 
pending further internal technical 
work, independent certification of 
one or both fields may be undertaken 
if required to support progression 
of a viable development concept to 
commercialisation.

Alaska – Pikka Unit

External audit of the Pikka Unit 
Resources is proposed for 2019, which 
will provide certified numbers ahead of 
a Final Investment Decision on the Pikka 
Unit development, expected in 2020.

The Company booked 127.5 mmbbl of 2C oil resource at the Pikka Unit, following completion  
of its acquisition of Alaska North Slope assets in February 2018.

NOTES

1.  Numbers may not add due to rounding.

2.  Kutubu and Moran oil fields proved Reserves 

(1P) and proved and probable (2P) Reserves are 
as certified by independent auditor Netherland, 
Sewell & Associates, Inc. (NSAI) in 2017. 1P 
and 2P PNG LNG Project Reserves are based 
on Contingent Resources as certified in 2016 
by independent auditor, NSAI, adjusted for 
economic limit using Oil Search’s corporate 
assumptions. Gobe Main and SE Gobe 1P and 
2P Reserves are based on Oil Search 2018 
technical estimates.

3.  Crude oil, and separator and plant condensates.

4.  For the PNG LNG Project, shrinkage has been 
applied to raw gas for the field condensate, 
plant liquids recovery, and fuel and flare.

5.  PNG LNG Project Reserves comprise the 
Kutubu, Moran, Gobe Main, SE Hedinia, 
Hides, Angore and Juha fields. Minor volumes 
associated with proposed domestic gas sales 
have been included as part of PNG LNG 
reserves. In addition, third party wet gas sales 
to the project at the Gobe plant outlet (inclusive 
of plant condensate) have been included for SE 
Gobe in 1P and 2P Reserves at the post-sales 
agreement field interest of 22.34%. SE Gobe 
estimates for gas are based on Oil Search 2018 
technical estimates.

6.  Hides Reserves associated with the GTE Project 
under existing contract. Production volumes 
shown in this Reserves report are based on Oil 
Search’s entitlement in PDL 1 (16.67%).

7.  Other gas, oil and condensate Resources 
comprise the Company’s other PNG fields 

including Elk-Antelope, SE Mananda, Juha 
North, P’nyang, Kimu, Uramu, Barikewa, Iehi, 
Cobra, Mananda, Flinders and Muruk and may 
also include Resources beyond the current 
economic limit of producing oil and gas fields. 
These gas Resources may include fuel, flare, 
and shrinkage depending on the choice of 
reference point.

8.  Alaskan gas, oil, and condensate Resources 
comprise the Company’s share in Alaskan 
assets, incorporating the Nanushuk and satellite 
reservoirs in the Pikka Unit.

This Reserves and Resources statement is based on, 
and fairly represents, information and supporting 
documentation that has been prepared by, or under 
the supervision of, one of the qualified petroleum 
reserves and resources evaluators listed in the 
table below. Drs. Schakel, a full-time employee of 
Oil Search and qualified petroleum reserves and 
resources evaluator, has consented to publish this 
information in the form and context in which it is 
presented in this statement.

ADDITIONAL NOTES

•  The evaluation date for these estimates is 

31 December 2018.

•  Oil Search’s Reserves and Contingent Resource 
estimates are prepared in accordance with 
the 2007 Petroleum Resources Management 
System (PRMS), sponsored by the Society of 
Petroleum Engineers (SPE).

•  The following reference points are assumed:

 x Oil volumes: include both oil and condensate 
recovered by lease processing. The reference 
point is at the outlet of the relevant process 
facility. Volumes are adjusted to stock-tank 
using field standard conditions.

 x Hides GTE: the custody transfer point at 

the wellhead

 x PNG LNG Project: the outlet to the LNG plant

 x SE Gobe gas: the outlet to the Gobe facility

 x Fuel, flare and shrinkage upstream of 

the reference points have been excluded.

•  Reserves and Contingent Resources are 
aggregated by arithmetic summation by 
category and therefore Proved Reserves may 
be a conservative estimate due to the portfolio 
effects of arithmetic summation. 

•  Reserves and Contingent Resources have 

been estimated using both deterministic and 
probabilistic methods.

Production and Revenue
Oil Search’s total net production in 2018 of 25.21 million barrels 
of oil equivalent (mmboe) was lower than net production of 
30.31 mmboe in 2017, as it was impacted by the devastating PNG 
Highlands earthquake in late February 2018 which caused a 
complete production shut-in across both PNG LNG and operated 
facilities. Further details on performance by operating segment 
and field are included in Section 2 ‘Overview of operations’.

Despite lower production, total revenue of US$1,535.8 million 
was 6% higher than the prior year, bolstered by stronger 
average realised oil and gas prices during 2018. The average 
price realised for LNG and gas sales increased by 31%, 
compared to the prior year, to US$10.06/mmBtu. The average 
realised oil and condensate price for 2018 was US$70.65 per 
barrel, 27% higher than the prior year outcome. The Group did 
not have any oil hedges in place during the year and remained 
unhedged to oil price movements.

LNG delivered sales volumes totalled 111,008 billion Btu in 
2018, 10% lower than in the prior year, with the delivery of 99 
LNG cargoes (2017: 110 cargoes). Liquid volumes delivered in 
2018 totalled 4.94 million barrels (mmbbl), 34% lower than the 
7.50 mmbbl delivered in 2017, due to both the impact of the 
PNG earthquake and natural field declines. 

Other revenue, consisting mainly of rig revenue, electricity, 
refinery and naphtha sales, and infrastructure tariffs, decreased 
to US$49.7 million in 2018 from US$58.0 million in 2017. 

Production and other operating costs
Production costs increased by 10% from US$262.8 million 
in 2017 to US$290.0 million in 2018, mainly impacted by 
earthquake related work to reinstate production and repair 
damaged production facilities and other infrastructure. 
Recovery work performed during 2018, excluding an LNG 
cargo purchase required to restart the LNG plant, totalled 
US$63.3 million with just under half that  amount offset by 
insurance proceeds. Consequently, and together with lower 
overall production, production costs on a per barrel of oil 
equivalent (boe) basis increased from US$8.67 per boe in 
2017 to US$11.51 per boe in 2018.

Other operating costs increased from US$141.1 million in 2017 
to US$145.4 million in 2018.

Depreciation and amortisation
Depreciation and amortisation decreased from 
US$380.6 million in 2017 to US$326.1 million in 2018.

Amortisation costs decreased by US$52.2 million to 
US$310.0 million in 2018, primarily due to the curtailment 
of production following the PNG earthquake. On a cost 
per boe produced basis, the average amortisation rate for 
the producing assets was US$12.40 in 2018, compared to 
US$11.95 in 2017. 

Exploration costs expensed
In line with the Group’s successful efforts accounting policy, 
all costs associated with unsuccessful drilling, seismic work 
and other support costs related to exploration activity were 
expensed during the year and resulted in a pre-tax charge of 
US$66.7 million. This included US$33.7 million attributable to 
extensive seismic activity covering PRL 15, PPL 475, PPL 476, 
and PRL 39 in the Papuan Gulf Basin and PDL 4 and PRL 14 in the 
Forelands region of PNG. A further US$18.2 million was spent 
on exploration seismic, G&G and G&A activities in Alaska.

Further details on exploration activities during the year are 
included in Section 2 ‘Overview of operations’.

Net finance costs
Net finance costs of US$209.9 million in 2018 were 
US$15.2 million higher than the prior year and were impacted 
by higher US interest rates on PNG LNG and Corporate debt 
facilities, as well as the unwind of site restoration provisions. 

Taxation
Tax expense on statutory profit in 2018 was US$166.2 million, 
compared to US$138.8 million in 2017. This resulted in an 
effective tax rate of 32.8% for 2018, against an effective tax rate 
of 31.5% in 2017. This increase was largely driven by a one-off 
adjustment to deferred tax assets in 2017.

1.2 

Summary of Financial Position

Net debt
At 31 December 2018, Oil Search had net debt (total borrowings 
less cash) of US$2,693.0 million, a US$82.8 million increase 
on the prior year net debt position of US$2,610.2 million, due 
in part to the all-cash acquisition of licence interests in Alaska. 
A reconciliation of the movement in net debt between year-end 
balance dates is as follows:

At 31 December 2018, the Group had US$3,293.6 million of 
debt outstanding under the PNG LNG Project finance facility, 
with corporate credit facilities undrawn. 

Oil Search remained in a strong liquidity position at 
31 December 2018, with cash of US$600.6 million, including 
US$308.6 million in PNG LNG escrow accounts, and 
US$900 million available under the Group’s corporate facilities. 
In December 2018, the Company increased its corporate 
credit facilities, to a total of US$900 million, after entering into 
three new US$100 million bilateral revolving credit facilities 
that replaced two US$125 million bilateral facilities. The three 
new facilities expire in December 2023 and the Company’s 
US$600 million syndicated facility, refinanced in 2017, expires 
in June 2022.

Investment expenditure
Total investment expenditure for 2018 was US$835.4 million, 
compared to US$277.6 million in 2017 with the increase 
predominantly due to a significant expansion of the company’s 
growth portfolio. During 2018 Oil Search completed several 
asset acquisitions, including licence interests in the North Slope 
of Alaska and multiple licence interests in the onshore Papuan 
Gulf basin. Oil Search also completed one of the largest seismic 
acquisition programmes in the Company’s history in PNG. 
Pre-FEED activities for the PNG gas expansion projects under 
the PRL 15 and PRL 3 licences were ongoing during the year.

US$231.0 million (2017: US$158.8 million) and US$483.5 
million (US$7.9 million) in PNG and the USA respectively. Major 
expenditures in PNG in 2018 included US$73.1 million on 
PPL402/PDL9, Muruk 2, PRL 8 Kimu, PRL 9 Barikewa appraisal 
drilling, US$54.9 million on pre-FEED activity for the PRL 15 
and PRL 3 expansion projects, US$33.3 million on seismic 
acquisition activity and US$45.1 on licence acquisition costs. 
US$483.5 million was spent in Alaska, including the acquisition 
of licence interests, seismic acquisition and preparatory works 
for appraisal drilling that commenced on 31 December 2018.

Development expenditure for 2018 was US$47.5 million 
(2017: US$39.9 million). This included Oil Search’s share of PNG 
LNG Angore development costs of US$36.8 million, where 
activity has been suspended pending the easing of inter-tribal 
tensions. In addition, US$10.7 million was spent predominantly 
on developing forestry assets for the Biomass project. 

Expenditure on producing assets totalled US$21.7 million in 
2018 (2017: US$40.7 million) and largely comprised sustaining 
capital expenditure for PNG LNG and PNG oil and gas assets. 

The increase in other plant and equipment expenditure from 
US$27.6 million in 2017 to US$51.4 million in 2018, was mainly 
associated with implementation costs for the Company’s new 
Enterprise Resource Planning (ERP) system.

Operating cash flow was largely unchanged year-on-year, with 
higher revenues from higher average realised prices offset by 
lower sales volumes, earthquake remediation costs, higher 
exploration seismic, G&A and G&G activities, higher taxes paid 
and higher borrowing costs.

During 2018, Oil Search’s net investing cash flow included 
expenditures of:

 ¸ US$647.6 million on exploration and evaluation 

(US$157.3 million in 2017);

 ¸ US$56.4 million on other plant and equipment 

(US$38.1 million in 2017); 

 ¸ US$41.7 million on payments made in respect of power

 ¸ US$36.9 million on projects under development 

(US$21.1 million in 2017); and

 ¸ US$26.2 million of capital investment on production 

activities (US$38.2 million in 2017).

The Group distributed US$114.3 million to shareholders 
by way of the 2017 final dividend and the 2018 interim 
dividend during the year. During 2018, borrowings of 
US$331.9 million (2017: US$313.9 million) were repaid under 
the PNG LNG Project finance facility, in accordance with the 
repayment schedule.

Reserves and Resources 

1.4 
As at 31 December 2018, the Company’s Proved Reserves (1P) 
were 54.1 million barrels (MMbbl) oil and condensate, down 
from 59.1 MMbbl in 2017 and 1,937.1 billion cubic feet (bcf) gas, 
down from 2,040.5 bcf in 2017.

The Company’s total Proved and Probable Reserves (2P) 
plus Contingent Resources (2C) for oil and condensate were 
253.5 MMbbl, up 101.5% compared to 2017. The movements 
reflect the addition of 127.5 MMbbl of Alaskan Pikka Unit oil to 
2C Contingent Resources, as well as 5.2 MMbbl of P’Nyang 
condensate to 2C, after the successful drilling of the P’Nyang 
South 2ST1 appraisal well. These additions were partially offset 
by net production of 4.9 MMbbl and minor changes to the 
Gobe Main and SE Gobe field 2P oil Reserves.

Total Proved and Probable Reserves (2P) plus Contingent 
Resources (2C) for gas were 6,742.2 bcf, up 6.3% from 2017. 
The movements reflected an additional 186.7 bcf of 2C gas at 
Kimu, after the successful Kimu 2 appraisal well, as well as the 
addition of 319.8 bcf of 2C gas after the successful drilling of 
the P’Nyang South 2ST1 appraisal well. Those increases were

OVERVIEW OF OPERATIONS

2. 
Established in 1929, Oil Search is a Papua New Guinean (PNG) 
oil and gas exploration, development and production company. 

The Company operates all of PNG’s currently producing oil 
fields and the Hides Gas-to-Electricity Project and invests in a 
number of exploration licences in PNG and in the North Slope 
of Alaska. It also has a 29% interest in the PNG LNG Project, a 
world scale liquefied natural gas (LNG) development, operated 
by ExxonMobil PNG Limited. 

During 2018, Oil Search produced 25.2 million barrels of 
oil equivalent (mmboe). This compared to production of 
30.3 mmboe in 2017, reflecting the shut-in of operated 
production and the PNG LNG Project following a 7.5 
magnitude earthquake that struck the PNG Highlands in late 
February 2018. Having withstood the earthquake well, the 
PNG LNG Project came back online in April and ramped up to 
an annualised production rate of 8.8 million tonnes per annum 
(MTPA) in the second half of 2018, the highest half-year rate 
achieved since the Project came onstream in 2014. Oil Search’s 
operated production recovered progressively over the year, as 
remedial work was completed to restore damaged flow lines 
and bring wells back online. 

In 2018, Oil Search and its joint venture partners reached 
broad alignment on the preferred downstream development 
concept for the proposed construction of three new LNG 
trains, to be located on the existing PNG LNG plant site. 
The new trains will be underpinned by approximately 11 tcf of 
certified 2C gas resource from the Elk-Antelope fields in PRL 
15 (Papua LNG Project) and the P’nyang field in PRL 3. During 
the year, commercial arrangements to enable the integration 
of the Papua LNG Project and PNG LNG were broadly agreed 
and pre-FEED downstream studies, project financing and 
marketing discussions were advanced. In November 2018, a 
Memorandum of Understanding was signed between the PNG 
Government and the PRL 15 joint venture, outlining the key 
terms and conditions to be included within the Gas Agreement 
that will apply to the PRL 15 development. Oil Search expects 
the Gas Agreement to be finalised by the end of March 2019. 
The Gas Agreement between the State and the PRL 3 joint 
venture also is expected to be negotiated in a similar timeframe, 
allowing an integrated FEED entry on the proposed three-train 
development to take place. 

During the year, Oil Search continued to explore actively 
in PNG. The Company drilled four appraisal wells, farmed 
into four highly prospective licences in the onshore Gulf and 
completed one of the largest onshore seismic programmes 
in the Company’s history. 

In February 2018, Oil Search completed the acquisition of 
interests in the Alaska North Slope for US$400m, plus deal 
costs, and assumed operatorship in March 2018. The assets 
acquired include a 25.5% interest in the Pikka Unit, which 
contains a major undeveloped oil field. During the year, the 
Company built a world-class team in Anchorage, progressed 

the environmental permitting process for the Pikka Unit 
development towards its final stages and commenced a two-
well appraisal drilling programme in the Pikka Unit area.

2.1 

Production Activities 

2.1.1  PNG LNG Project (29%, non-operator) 
The PNG LNG Project produced 22.1 mmboe net to Oil Search 
in 2018, comprising 97.5 bcf of LNG and 3.0 mmbbl of liquids. 
Gross LNG production from the Project was 7.4 MT, 11% below 
2017 and representing a strong result given the eight-week 
production shut-in following the earthquake in February. 
The Project, which came back online in April, produced at 
an annualised rate of 8.8 MTPA in the second half of 2018 
(almost 30% above nameplate capacity), benefitting from 
planned modifications to the Hides Gas Conditioning Plant and 
maintenance work on the LNG trains, which were carried out 
during the production shut-in period. 

In 2018, 99 LNG cargoes were exported, with 73 sold under 
long-term contract, eight sold under mid-term sale and 
purchase agreements and 18 cargoes sold on the spot market. 
15 cargoes of Kutubu Blend and 10 cargoes of naphtha were 
also sold.

The Project entered into two mid-term LNG sale and purchase 
agreements (SPAs) with PetroChina and BP, totalling 0.9 MPTA 
over five years from 2018 to 2023. These new SPAs take total 
contracted volumes to approximately 7.5 MTPA. ExxonMobil, 
on behalf of the PNG LNG project participants, continued to 
negotiate the sale of the final mid-term tranche of 0.45 MTPA.

Work to tie the Angore field into the PNG LNG processing 
facilities was halted in early 2018 due to local unrest and 
remains suspended until tensions in the area subside. 

2.1.2  Operated oil and gas production 

Kutubu (PDL 2 – 60.0%, operator)
Gross production from the Kutubu complex in 2018 averaged 
7,451 bopd, down 38% from 2017 levels. 

Production from the Kutubu complex was shut-in in late February 
due to the Highlands earthquake. The Central Processing Facility 
(CPF) resumed operations in late March, allowing production 
from the Kutubu fields to recommence at an initial rate of 
approximately 4,000 barrels of oil per day (bopd). 

Moran (49.5%, based on PDL 2 – 60.0%, PDL 5 – 40.7% 
and PDL 6 – 71.1%, operator)
Gross production from Moran in 2018 averaged 1,715 bopd, 
down 76% from 2017 levels.

Given their proximity to the earthquake’s epicentre, the Agogo 
Processing Facility (APF) and the Moran and Agogo fields 
sustained the most damage from the earthquake. Production 
from Agogo fields resumed in late July, with total output 
building up to 2000 bopd by the end of the year as flowlines 
damaged during the earthquake were progressively repaired 
and production wells were brought back online. Earthquake 
damage to the high-pressure compression systems at the APF 
limited production rates from the Agogo field through the 
year, with remedial work to these systems completed in early 
2019. Production from Moran was shut-in from late February to 

85

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
O p erati ng a n d Fin a n cial R ev iew

August while repairs to the APF, flowlines and well sites took place, allowing operations to resume. As mentioned above, damage 
to the compression systems at the APF also impacted the volume of hydrocarbons that could be processed from the Moran fields 
following the earthquake. Natural field decline also contributed to lower production levels in 2018.

Gobe Main (PDL 4 - 10%, operator) and SE Gobe (PDL 3 - 36.4% and PDL 4 - 10%, operator)
In 2018, gross production from the Gobe Main field declined 26% to 400 bopd, while production from the SE Gobe field was 38% 
lower, at 432 bopd. 

Production from both fields was impacted by the earthquake, with production recommencing in late April, following the 
completion of initial repairs and planned maintenance. Earthquake-related damage to key wells, including the G 7X well, continued 
to impact production rates through the second half of the year. 

In 2018, 17.9 bcf of gas (gross) was supplied to the PNG LNG Project from the Gobe Main and SE Gobe fields, compared to 26.7 
bcf in 2017.

Hides Gas to Electricity (GTE) Project – 100%, operator (PDL 1 – 16.7%) 
The Hides GTE Project produced 4.0 bcf of gas in 2018, 32% lower than in 2017, and 83,000 barrels of liquids, down 29% on 2017 
levels. The Hides Gas-to-Electricity (GTE) facilities resumed operations in May, after the completion of earthquake-related repairs to 
the Porgera Joint Venture electricity generation facility.

(1)  Numbers may not add due to rounding.

(2)  Gas and LNG volumes have been converted to barrels of oil equivalent using an Oil Search specific conversion factor of 5,100 scf = 1 boe, which represents a 

weighted average, based on Oil Search’s reserves portfolio, using the actual calorific value of each gas volume at its point of sale. This reflects the energy content 
of the Company’s gas reserve portfolio. Minor variations to the conversion factors may occur over time. 

In 2018, the Company carried out a major analysis on how to optimise production from its mature and declining oil fields in PNG. 
A range of new drilling and workover opportunities were identified for implementation over the 2019 to 2023 period, with the 
potential to add approximately 30 million barrels to Oil Search’s oil reserves on a risked basis. 

During the year, work also progressed on the Associated Gas Expansion (AGX) Project, which seeks to accelerate the delivery of gas 
from the Oil Search-operated Kutubu, Agogo and Moran fields to the PNG LNG Project. Studies have confirmed that AGX feedstock 
gas could provide a source of cost effective gas to front-end the proposed PNG LNG/P’nyang expansion train. The project passed 
the concept screening phase in 2018 and the Company is targeting selection of the preferred development concept to enable a 
decision on FEED entry in 2019.

2.2  Gas Development 
In 2018, Oil Search and its joint venture partners, ExxonMobil 
and Total, reached broad alignment on the preferred 
downstream development concept for a proposed expansion 
of LNG capacity in PNG. This comprises the construction of 
three LNG trains, with a total capacity of 8 MTPA, located on the 
existing PNG LNG plant site. Two of the trains will be dedicated 
to the Papua LNG Project and will be supplied with gas from 
the Elk-Antelope fields in PRL 15, while the third train will be 
underpinned by gas from the existing PNG LNG Project fields 
and the P’nyang field in PRL 3. By integrating the new trains 
with the existing PNG LNG Project, material construction and 
operating cost savings are expected to be realised through 
the sharing of infrastructure and personnel.

During the year, commercial agreements supporting the 
integration of both projects with the existing PNG LNG 
Project infrastructure were broadly agreed. Project financing 
discussions advanced and pre-FEED downstream studies 
were matured, including engineering work on the design, 
process and layout optimisation of the three-train development 
concept, from the gas inlet to the LNG loading arm. In addition, 
Oil Search established a regional office in Tokyo, staffed with a 
highly experienced LNG team, to market its equity share of LNG 
from the Papua LNG Project. Engagement with potential LNG 
buyers in key Asian markets has been positive, with significant 
interest expressed for additional LNG volumes from PNG.

In November, a Memorandum of Understanding (MOU) was 
signed between the PNG Government and PRL 15 (Papua LNG) 
Joint Venture. This MOU provides the framework for key terms 
and conditions to be included within the Gas Agreement, 
including tax arrangements and a Domestic Market Obligation, 
as well as a timeline for the finalisation of negotiations by the 
end of March 2019. Discussions also advanced between the 
PNG Government and the PRL 3 joint venture, with a Gas 
Agreement also expected to be finalised in the same timeframe, 
allowing an integrated FEED entry decision on the proposed 
three-train development.

In early 2018, independent recertification of the P’nyang field, 
incorporating results from the P’nyang South 2 ST1 appraisal 
well and additional seismic and core data, resulted in a tripling 
of the certified gross 1C gas resource to 3.51 tcf and an increase 
in 2C gross resources to 4.36 tcf. Combined with gas resources 
in the Elk-Antelope fields, there is approximately 11 tcf of 
certified 2C gas resource available to underpin the proposed 
additional LNG capacity.

Exploration and appraisal activities 

NW Highlands
Preparations to drill the Muruk 2 appraisal well in PDL 9 
(Oil Search – 24.4%), which were halted by the Highlands 
earthquake in early 2018, resumed in the third quarter. Well site 
construction and mobilisation of the rig to site were completed 
and the well commenced drilling in November 2018. Muruk 2 is 
located approximately 11 kilometres north-west of the Muruk 1 
gas discovery well and aims to delineate the potential resource 
volume in the Muruk field. Oil Search was contracted to drill 
the Muruk 2 appraisal well on behalf of the operator of PDL 9, 
ExxonMobil. Given its location near Hides, Muruk could be a 
valuable source of gas for either a new LNG train or as back-fill 
for the PNG LNG Project. 

87

A 2D seismic programme covering approximately 
100 kilometres over Muruk and adjacent acreage, which was 
interrupted by the earthquake, is planned to recommence in 
late 2019/early 2020. This will help mature potentially drillable 
prospects along the Hides-P’nyang trend, which the Company 
estimates could hold more than 10 tcf of unrisked gas. Due to 
its proximity to existing and planned infrastructure, Muruk and 
other prospects in the Hides-P’nyang fairway offer optionality 
for sourcing gas to underpin an additional LNG train, or as 
backfill for the PNG LNG Project. 

Forelands / Onshore Gulf
During the year, the Company successfully drilled the Kimu 2 
and Barikewa 3 appraisal wells in the PNG Forelands. 

The Kimu 2 appraisal well in PRL 8 (Oil Search – 60.7%, 
operator) spudded in late April and reached total depth in 
late May, after intersecting gas in the target Alene Sandstone 
formation. A Drill Stem Test was conducted over the interval, 
confirming excellent reservoir quality, before the well was 
plugged and abandoned as planned.

The Barikewa 3 appraisal well in PRL 9 (Oil Search – 45.1% 
operator) spudded in June and reached total depth in 
July, successfully encountering gas in the target Toro and 
Hedinia Sandstone reservoirs. Both reservoirs were well 
developed, with testing indicating a clean, dry gas comprising 
approximately 20% nitrogen, in line with expectations. The well 
was plugged and abandoned as planned.

Evaluation of the data from both wells, together with an update 
on the subsurface interpretation, is expected to be completed 
in early 2019. These findings will help to constrain the resource 
base of the Kimu and Barikewa fields and assist in selecting the 
optimal route for potential commercialisation.

In the onshore Gulf, Oil Search completed the acquisition of 
a 25% interest in four highly prospective leases, PPL 474, 475 
and 476 and PRL 39, located adjacent to the Elk-Antelope 
fields in PRL 15. During the year, the first phase of a 2D seismic 
programme, covering 330 kilometres over these ExxonMobil-
operated licences and over the Total-operated PRL 15 licence 
was completed. A second phase, covering approximately 
250 kilometres, commenced in late 2018 and is expected to 
conclude by mid-2019. Data from these surveys will help to 
mature identified leads and prospects located near planned 
Papua LNG infrastructure for potential future drilling.

In the Forelands, a 50-kilometre seismic programme was 
completed to assess the potential of the Gobe Footwall 
exploration prospect in PDL 4 and help further constrain 
the lehi gas discovery in PRL 14.

Offshore Papuan Gulf
During the year, Oil Search continued to optimise offshore Gulf 
3D seismic data sets to constrain the acreage’s prospectivity. 
In the shallow water offshore Gulf, a gravity gradiometry and 
magnetics survey was acquired and studies on the Uramu 
discovery in PRL 10 (Oil Search – 100%, operator) also took 
place to ascertain its viability for appraisal drilling. In the 
Deepwater Gulf, evaluation of 2D seismic data continued 
and identified prospects were risked, ranked and prioritised. 
The Company is considering acquiring 3D seismic in late 
2019 or 2020 to mature prospects further.

Power

2.4 
In 2018, NiuPower Ltd, a 50:50 joint venture between Oil 
Search and Kumul Petroleum, commenced construction of a 
58 MW gas fired power station located next to the PNG LNG 
plant site. PNG LNG will contribute 100% of the gas supply. 
The power station seeks to provide the cheapest source of 
electricity to Port Moresby, benefitting local individuals and 
businesses. Construction of the power station was completed 
in February 2019, with commissioning activities underway 
ahead of first supply expected in March 2019. 

Alaska

2.5 
In February 2018, Oil Search completed the acquisition 
of interests in the Alaska North Slope for US$400 million, 
excluding transaction costs, and assumed operatorship of 
the assets in March 2018. Assets acquired included a 25.5% 
interest in the Pikka Unit and adjacent exploration acreage, a 
37.5% interest in the Horseshoe Block, as well as an additional 
25.5% interest in adjacent exploration acreage. 

Approximately 500 million barrels (gross) of 2C oil resource 
was assigned to the Pikka and satellite oil fields for acquisition 
purposes. However, there is material resource upside, which 
is being tested in the 2018/19 appraisal drilling programme, 
comprising two wells, Pikka B and Pikka C. If successful, these 
wells have the potential to add up to 250 mmbbl to the current 
2C resource estimate of 500 mmbbl (gross) of oil and will help 
define the optimal well design for the Pikka Unit development.

Both appraisal wells comprise a vertical hole and a sidetrack, 
allowing four reservoir penetrations to confirm the presence, 
volume, thickness and quality of the Nanushuk reservoir at 
the Pikka B and Pikka C locations. Testing will confirm well 
deliverability, which will feed into the selection of the well 
design that will be used in the Pikka Unit development. 

The Pikka B well spudded in late December and penetrated the 
target Nanushuk formation in early January 2019, successfully 
encountering hydrocarbons, in line with pre-drill expectations. 
Cores were acquired and open-hole logging runs completed 
before the wellbore was plugged and abandoned and a side 
track, Pikka B ST1, kicked off. The forward plan is to drill ahead 
and acquire additional cores in the Nanushuk 3 sands before 
conducting a well test.

The Pikka C well spudded in late January and is drilling ahead. 
The forward plan is to drill through to the Nanushuk Formation, 
evaluate, then drill a side track to build a lateral section in the 
reservoir. The well will then be completed and flow tested.

Initial concept select evaluations took place during the year, 
which indicated the most likely development concept as a 
120,000 bopd processing facility, with production from three 
drill sites (of which two will be developed initially, with one 
in reserve). Further facility processing studies are currently 
underway to confirm the optimal configuration. 

Over 2018, the Company made good progress advancing 
the environmental permitting process for the Pikka Unit 
development. Following consultation with local communities, 
the Company proposed enhancements to the project concept 
that have addressed community concerns and the Final 
Environmental Impact Statement was issued in November. 
Oil Search expects the Record of Decision to be granted late 

88

in the first quarter of 2019, enabling the joint venture to proceed 
to front end engineering and design (FEED) in mid-2019. 

During the year, work took place to optimise the value of Oil 
Search’s option to double the Company’s interests in the 
assets acquired for the payment of a further US$450 million. 
Oil Search anticipates this will involve exercising the option, 
prior to its expiry on 30 June 2019, and on-selling a portion 
of the interest to introduce one or two additional participants 
into the assets. There has been significant market interest in 
the opportunity and towards the end of the year, Oil Search 
commenced discussions with potential new partners. 

In late 2018, the Company acquired lease interests covering 
over 20,000 acres in areas surrounding the Pikka Unit. 
These leases significantly enhance the Company’s exploration 
prospects, and if future drilling proves successful, could 
be developed utilising infrastructure planned for the Pikka 
development. In addition, the Company acquired interests 
in leases covering approximately 195,200 gross acres in 
the eastern area of the Alaska North Slope, which has been 
identified in a regional study as being highly prospective for oil.

Since assuming operatorship, Oil Search has built a highly 
experienced, multi-disciplinary team based in Anchorage. 
At the end of 2018, approximately 100 employees and 
contract staff, with diverse backgrounds in the global and local 
Alaskan oil industry had been recruited, including all senior 
department heads.

expenditure. If Oil Search is unable to obtain additional funding 
on acceptable terms in these circumstances, its financial 
condition and ability to continue operating may be affected.

The Group’s financial risk management strategy to address 
liquidity risk is outlined in note 27 in the financial statements. 
The Group also institutes regular short, medium and long-
term forecasts to assess any implications for future liquidity 
and profitability.

 ¸ Select the preferred development concept for the AGX 

opportunity and enter FEED.

Operational risks

 ¸ Implement the Company’s revised stakeholder 

management plan in PNG. 

 ¸ Enter FEED on the Pikka Unit development in Alaska.

 ¸ Optimise the value of the Alaskan licence equity option, 

including a potential on-sale of part of the equity acquired. 

 ¸ Continue to focus on the development and enhanced 

engagement of staff.

3.3  MATERIAL BUSINESS RISKS
The scope of the Group’s operations, the nature of the oil and 
gas industry and external economic considerations mean that 
a range of factors may impact results. Material business risks 
that could impact Oil Search’s results and performance are 
described below. 

These risks are not the only risks that may affect the Group. 
Additional risks and uncertainties not presently known to 
management or that management currently believe not to 
be material may also affect Oil Search’s business.

Financial and Liquidity risks

Pricing risk
Oil Search’s business is heavily dependent on prevailing market 
prices for its products, primarily oil and gas. Changes in the 
prices of these commodities will impact the Group’s revenue 
and cash flows. There are a number of macroeconomic factors 
that influence oil pricing, over which Oil Search has no control. 

Oil Search has executed long term sales and purchase 
agreements for the supply and sale of the majority of its 
LNG production with pricing mechanisms established under 
these agreements.

The Group’s financial risk management strategy to address 
commodity price risk is outlined in note 27 in the financial 
statements. The Group’s Audit and Financial Risk Committee 
is responsible for reviewing the policies, processes, practices 
and reporting systems covering the Group’s exposure to 
financial risks.

Future operating and capital cost requirements
Future operating and capital cost requirements may be 
impacted by multiple external and internal factors, many of 
which have been identified elsewhere through this section. 
Unexpected changes to future cost profiles could result in Oil 
Search’s cash requirements being over and above its available 
liquidity. To the extent that the Group’s operating cash flows 
and debt facilities are insufficient to meet its requirements for 
ongoing operations and capital expenditure, Oil Search may 
need to seek additional funding, sell assets or defer capital 

89

Production
Oil and gas producing assets may be exposed to production 
decreases or stoppages, which may be the result of facility shut-
downs, mechanical or technical failure, well, reservoir or other 
subsurface impediments, safety breaches, natural disasters and 
other unforeseeable events. A significant failure to maintain 
production could result in the Group lowering production 
forecasts, loss of revenues and incurring additional costs to 
reinstate production to expected levels. 

Safety and environmental
Oil and gas producing and exploration operations are also 
exposed to industry operational safety risks including fire, 
explosions, blow-outs, pipe failures, as well as transport and 
occupational safety incidents. Major environmental risks 
include accidental spills or leakage of petroleum liquids, gas 
leaks, ruptures, or discharge of toxic gases. The occurrence 
of any of these risks could result in substantial losses to the 
Group due to injury or loss of life; damage to or destruction of 
property, natural resources, or equipment; pollution or other 
environmental damage; cleanup responsibilities; regulatory 
investigation and penalties or suspension of operations. 
Damages occurring to third parties as a result of such risks may 
also give rise to claims against the Group. 

The Group’s Health, Safety, Environment and Security (HSES) 
Policy details the Company’s commitment to achieving 
incident free operations through the provision of effective 
HSES management across all of its operations and worksites. 
The Policy is implemented via a number of underpinning 
procedures, steering groups and incentive measures to ensure 
high standards of HSES management are maintained. In 
addition, the Group’s drilling, production, processing, refining 
and export activities in PNG operate under an environmental 
management system that is certified as ISO 14001 compliant. 

In addition, the PNG highlands were subject to a major 
earthquake in February 2018 and Oil Search’s infrastructure 
and facilities sustained some damage, with remediation work to 
reinstate the damaged assets ongoing. The unresolved damage 
escalates both the production and safety/environmental risks as 
a consequence.

Cyber security
The integrity, availability and reliability of data within Oil 
Search’s information technology systems may be subject 
to intentional or unintentional disruption. Given the level of 
increasing sophistication and scope of potential cyber attacks, 
these attacks may lead to significant breaches of security 
which could jeopardise the sensitive information and financial 
transactions of the Group. 

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
O p erati ng a n d Fin a n cial R ev iew

The Group manages operational risk through a variety of 
means including: strict adherence to its operating standards, 
procedures and policies; staff competency development and 
training programmes and through the effective use of a Group-
wide risk management system to ensure that the Group’s 
operational controls are continuously improved. In addition, the 
Group has insurance programmes in place that are consistent 
with good industry practice.

Reserves, resource and development risks

Reserves decline and replacement
Oil Search, like any oil and gas company, is subject to reserves 
depletion and its impact on organisational value. Oil Search 
aims to replace and grow its reserve and resource base via 
exploration and commercial activities. The longer term health 
of the business will depend on the quality and size of its current 
asset and opportunity portfolio and the investment decisions it 
makes over many years. 

Oil and gas exploration is a speculative endeavor and each 
prospect/investment carries a degree of risk associated with 
the discovery of hydrocarbons in commercial quantities, 
which is more challenging for smaller fields in a lower 
commodity price environment. The value of exploration and 
development assets can be affected by a number of different 
factors including, amongst other things, macro-economic 
and socio-political conditions, changes to reserves estimates, 
the composition of oil and gas reserves, unforeseen project 
difficulties and other operational issues. Similarly, the economic 
value of the Group’s individual producing assets declines 
as oil and gas is produced. Oil Search’s future production 
profitability is subject to both subsurface and commodity price 
uncertainties but is also highly dependent on how Oil Search 
manages and maximizes the value of the production business 
over this period. 

The Group’s Board and management’s investment review 
committee oversee all significant investment decisions, each of 
which are subject to economic and risk analysis and assurance 
activities at specific gates, in line with the Group’s management 
system. Further, the Group also employs significant exploration, 
drilling and development teams who regularly monitor the 
Group’s prospects inventory and exploration plan, and lead 
activities to identify and develop the Group’s reserves. For 
producing assets, the Group has a life-of-asset planning 
process which guides the long term management of operated 
producing assets.

Reserves and resource estimates
Underground oil and gas reserve and resource estimates are 
expressions of judgment based on knowledge, experience and 
industry practice. Estimates which are valid at a certain point 
in time may alter significantly or become uncertain when new 
oil and gas reservoir information becomes available through 
additional drilling or reservoir engineering over the life of the 
field. As reserve and resource estimates change, development 
and production plans may be altered in a way that may affect 
the Group’s operations and/or financial results.

Additionally, oil and gas reserves and resources assume that the 
Group continues to be entitled to production licences over the 
fields and that the fields will be produced until the economic 

limit of production is reached. If any production licences for 
fields are not renewed or are cancelled, estimated oil and 
gas reserves and resources may be materially impacted. 

The Group employs the appropriate internal expertise to 
estimate reserves and resources and to prepare the Annual 
Reserves Statement in compliance with the ASX listing rules. 
In addition, material proven (1P) and proven and probable 
(2P) oil and gas field reserves are periodically certified by 
independent auditors.

Project development and execution
To achieve continual growth, Oil Search and its partners commit 
significant capital to the initiation, development and delivery 
of major projects, such as the successful PNG LNG Project. 
A number of factors influence the successful delivery of projects 
of this scale and/or complexity in our operating contexts, 
ranging from commercial and political risks in development 
to operational risks on delivery. Oil Search is undertaking or 
planning to undertake a number of significant projects in the 
coming years across its PNG, corporate and Alaskan assets, 
with a number of these projects planned to enter the Front End 
Engineering and Design (FEED) phase in 2019. These projects 
include both hydrocarbon development and corporate/PNG 
capability building, and can be led either by Oil Search or one 
of its JV partners. Each project has its own set of substantial risks 
that may affect organisational value. 

In line with the Group’s Opportunity Delivery Framework, the 
Group has a defined process by which it develops and executes 
capital projects under the guidance of its project assurance 
team and dedicated project managers. Further, a dedicated 
team is in place to closely monitor Oil Search’s major joint 
venture-led projects. The Group’s Board and management’s 
investment review committee oversee all significant investment 
decisions for these projects, each of which are subject to 
economic and risk analysis and assurance activities at specific 
gates within the Opportunity Delivery Framework. 

External and stakeholder risks

Legislative and regulatory risk
Oil Search has interests in international jurisdictions and 
therefore the business is subject to various national and local 
laws and regulations in those jurisdictions. Non-compliance can 
lead to regulatory or legal actions, and can impact the status of 
licenses or operatorship. Changes in government policy, the 
fiscal regime, regulatory regime or the legislative framework 
could impact the Group’s business, results from operations or 
financial condition and performance. 

The possible extent of such changes that may affect the Group’s 
business activities cannot be predicted with any certainty. 
The effects of any such actions may result in, amongst other 
things, increased costs, whether in the nature of capital or 
operating expenses, taxes (direct and indirect) or through 
delays or the prevention of the Group to be able to execute 
certain activities. 

Companies in the oil and gas industry may be subject to 
paying direct and indirect taxes, royalties and other imposts 
in addition to normal company taxes. The Group’s profitability 
may be affected by changes in government taxation and royalty 
policies or in the interpretation or application of such policies.

90

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
O p erating a n d Fin a n cial R ev iew

Climate Change
The Group is exposed to a number of climate change-related 
risks. Material climate-related risks include: changes in demand 
for our products due to regulatory and technological changes 
(transitional risk); increases in operating costs of assets due to 
carbon-pricing policies or other market mechanisms; physical 
damage to assets or interruption to operations from climatic 
changes and extreme weather events; and reputational 
damage driven by stakeholder activism and changing societal 
expectations. The occurrence of any of these risks could result 
in asset impairment, lost revenue and damage to brand value, 
amongst other things. 

The Company undertakes climate scenario analysis to test 
resilience to various transition related risks and uses an 
internal carbon price to assess potential cost impacts from 
the introduction of emissions-based market mechanisms. 
Technical design for major capital works projects are also 
required to consider the potential physical impacts on a range 
of climate outcomes. The Group’s Climate Policy details the 
Company’s expectations and commitments to assessing, 
responding and reporting climate change risks, implications 
and management approach.

Joint venture risk
Oil Search derives significant revenues and growth through 
joint venture arrangements. The use of joint ventures is common 
in the oil and gas industry and usually exists through all stages 
of the oil and gas lifecycle. Joint venture arrangements, amongst 
other things, can serve to mitigate the risk associated with 
exploration success and capital intensive development phases. 
However, failure to establish alignment between joint venture 
participants and with Government, negligence or competency 
levels of joint venture operators, or the failure of joint venture 
partners to meet their commitments and share of costs and 
liabilities, could have a material impact on the Group’s business 
or reputation. 

The Group manages joint venture risk through its careful joint 
venture partner selection (when applicable), stakeholder 
engagement and relationship management. Commercial 
and legal agreements are also in place across all joint 
associations which bind the joint venture participants to certain 
responsibilities and obligations.

In addition to changes in existing tax laws, risk is also 
embedded in the interpretation or application of existing tax 
laws, especially where specific guidance is unavailable or has 
not been tested in the relevant tax jurisdiction. 

Political, community and other stakeholders
The countries in which Oil Search has interests expose the 
organisation to different degrees of political and commercial 
risk. The overall socio-political environment in which Oil Search 
operates, the profitability of particular operating assets and the 
safety of people may be adversely impacted by political instability, 
land ownership disputes, ongoing benefits delivery delays, and 
community issues as well as war, civil unrest and terrorism. 

Community incidents occurred in PNG in 2018, and a 
heightened threat continues into 2019. This exposure changes 
as the external conditions evolve and as Oil Search enters new 
licenses or exits existing areas, regions and countries, as well 
as through different stages of the asset lifecycle. Oil Search’s 
ability to acquire, retain and gain full value from assets may 
also be affected by a number of political and social issues 
such as differing political agendas and decision making, 
environmental and social policy and the impact of bribery and 
corruption. Further, the media, non-government organisations 
and other activists may play an increasing role at local, national 
and international levels influencing political policy, societal 
perception and community actions or otherwise impacting 
the organisation’s reputation. Delays in government-led 
infrastructure development can also impact the commercial 
outcome of projects.

Oil Search operates under its Stakeholder Engagement 
standards and policies which require transparent, open, pro-
active communication and cooperation between the Company 
and government at all levels. Oil Search operates dedicated 
teams to manage government relations, which amongst other 
things, are targeted towards minimising risk that could arise 
out of potential fiscal, tax, resource investment, infrastructure 
access or regulatory and legal changes. Oil Search also has in 
place a comprehensive corruption prevention framework.

Oil Search also strives to minimise any negative impact of the 
Group’s operations on local society, culture and environment 
while contributing to local community and economic 
development so as to leave a positive legacy. The Group 
spends considerable time, effort and expense in working with 
government and communities, led by a dedicated Stakeholder 
Engagement team working in conjunction with Oil Search’s 
Security team. The Health, Safety and Sustainability Committee 
provides oversight of the strategies and processes adopted 
by management and monitors the Group’s performance and 
exposures in these areas. 

Human rights 
The Group may face risks related to the potential impacts of 
actions of both public and private security forces, interactions 
with and the use of land associated with subsistence-based 
and/or indigenous communities and the work practices 
of contractors. The Group’s human rights risk profile is 
updated regularly. Human rights due diligence is conducted 
in accordance with the UN Guiding Principles for Business 
and Human Rights.

Chair of the People & Nominations Committee

Dear Fellow Shareholders,
On behalf of the Board, I am pleased to present Oil Search Limited’s Remuneration Report for 2018.

The purpose of this introductory letter is to summarise key remuneration outcomes for 2018, explain how those outcomes are 
aligned with company performance, and to flag enhancements made during the year. 

Your Board is confident that Oil Search’s remuneration strategy and practices are appropriate and that they continue to:

 ¸  ensure alignment between shareholders and executives;

 ¸  provide a clear link between performance and remuneration outcomes; and

 ¸ ensure remuneration outcomes are consistent with Oil Search’s long term strategic objectives and incentivise the delivery of 

long term shareholder wealth creation.

Changes to fixed remuneration during 2018
Senior Management received modest increases in fixed remuneration during 2018 (generally 2.5%), and this was broadly in line 
with the salary review budget approved for other Australian based employees.

Short Term Incentive outcome for 2018
The Company has delivered strong performance in 2018 against the backdrop of a significant earthquake in the PNG Highlands 
which impacted both operated and non-operated production for a significant period. Operationally, Oil Search achieved better 
than target personal and process safety performance, which was particularly impressive in the circumstances, and the return to 
production was delivered more quickly than initially anticipated without a single recordable injury. As described earlier in the 
Annual Report, Oil Search’s achievements as ‘first responder’ to the local communities impacted by the earthquake has received 
considerable recognition both nationally and internationally. 

2018 saw the recognition of a major new oil resource addition associated with the Alaska North Slope farm-in. This was not 
recognised in the 2017 scorecard as the transaction was still subject to approval by the Committee on Foreign Investment in the 
US at 2017 year end. This approval was received in February 2018 and Oil Search assumed operatorship of the Alaskan assets in 
March 2018. Since then the company has built a world class team in Anchorage totalling more than 100 employees. 

In recent years, the Board has established a track record of applying discretion to the scorecard result to ensure that it considers 
factors not anticipated at the start of the year and that the interests of shareholders and employees are appropriately aligned and 
balanced. Reflecting the extraordinary events of 2018, and to ensure STI outcomes considered both the shareholder experience 
resulting from deferred production due to the February 2018 earthquake and the significant efforts of the company in response 
to the earthquake, the Board has resolved to exercise its discretion and has adjusted the size of the final STI pool available 
for distribution.

Firstly, an adjustment was made to acknowledge that shareholders had experienced a deferred production opportunity loss arising 
from the earthquake of approximately two months of production. The Board acknowledges that while this is deferred production 
which will be produced in later years, the deferred opportunity occurred during a period of high hydrocarbon prices relative to 
recent years and the STI outcome should be reduced to reflect that. Balancing that adjustment, the Board also acknowledges that 
Oil Search and Managing Director & CEO Peter Botten played a lead role in coordinating the regional response to the earthquake 
and that employees were considerably stretched to recover operations from the impacts of the earthquake. Field-based staff who 
remained on site in the period immediately after the earthquake experienced many heavy aftershocks and endured basic living 
conditions whilst reconstructing accommodation facilities, restoring power and adequate supplies of potable water. The entire 
organisation worked with a singular focus to return to business as usual as quickly as possible. Significantly, not one recordable 
injury was recorded during the restoration of services and production. The business outcomes achieved in 2018 reflect the 
dedication and commitment of all staff.

These adjustments when combined have resulted in an overall STI outcome for 2018 of 92% of Opportunity. Consistent with prior 
years, 50% of STI outcomes for Executives are awarded in the form of Restricted Shares which are subject to a further two-year 
deferral period.

The LNG expansion projects continue to make progress indicated by the signed Memorandum of Understanding with the State of 
PNG at the APEC conference held in Port Moresby during November 2018. As noted below, and subject to timely achievement of 
the agreed initiatives, progress on LNG expansion will be recognised and rewarded under the LNG Expansion Incentive approved 
by shareholders at the 2018 Annual Meeting rather than the STI scorecard. That incentive will be delivered predominantly in 
equity vesting two years after the achievement of the Final Investment Decision provided that it occurs within a timeframe which is 
acceptable to the Board. 

Vesting of Long Term Incentive awards from 2016
Performance Rights granted under the 2016 Long Term Incentive awards were tested based on Total Shareholder Return (“TSR”) 
performance over the period 1 January 2016 to 31 December 2018. 

Oil Search’s TSR was between the lower quartile and median against both the ASX50 peer group and the international Oil & Gas 
peer group. 

This meant that none of the 2016 Performance Rights vested. There are no re-testing provisions in the Long Term Incentive scheme 
and the 2016 Performance Rights awards have therefore lapsed.

Thank you for taking time to review our Remuneration Report and we look forward to welcoming you to our 2018 Annual Meeting.

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
R emu n eratio n R ep o r t

This report has been prepared in accordance with section 
300A of the Australian Corporations Act 2001 and summarises 
the arrangements in place for the remuneration of Directors and 
Executive Key Management Personnel and other employees of 
Oil Search for the period from 1 January 2018 to 31 December 
2018. Although it is not a requirement for PNG companies, 
Oil Search has voluntarily complied with section 300A of the 
Australian Corporations Act 2001 to ensure it meets current 
best practice remuneration reporting for ASX listed companies.

REMUNERATION POLICY 

1. 
The objectives of the Oil Search remuneration policy are to:

 ¸  Attract, retain and motivate the talent necessary to create 

value for shareholders;

 ¸  Reward Executives and other employees fairly and 

responsibly, having regard to the performance of Oil 
Search, the competitive environment and the individual 
performance of each employee; and

 ¸  Comply with all relevant legal and regulatory provisions. 

Oil Search’s approach to remuneration is based upon 
“Reward for Performance”, and remuneration is differentiated 
based on various measures of corporate, business unit/function 
and individual performance.

Remuneration for non-executive directors was established 
using data from external independent consultants which is 
updated from time to time and takes into account: 

 ¸ The level of fees paid to non-executive directors of other 
ASX listed corporations of a similar size and complexity 
to Oil Search;

 ¸ The international scale of Oil Search activities;

 ¸ Responsibilities of non-executive directors; and

 ¸ Work requirements of Board members. 

SHARE TRADING POLICY

2. 
Oil Search has a share trading policy in place for all employees, 
including Executives and Directors, which is available on the 
Oil Search website in the Corporate Governance Section. 
Under this policy there are three groups of employees:

 ¸ Restricted Employees – Directors, Executive General 
Managers and their direct reports, General Managers 
and their direct reports and other employees notified 
by the Group Secretary from time to time that they are a 
restricted employee;

 ¸ Prescribed Employees – particular employees, contractors 
or a member of a class of employees or contractors that are 
notified from time to time by the Group Secretary that they 
are prescribed employees due to the nature of work they 
are undertaking; and

 ¸ All Other Employees – any employee or contractor who 
is not classified as a Restricted or Prescribed Employee.

There are two specific periods defined in the share trading policy:

 ¸ Closed Period – the period from 1 January to 12 noon on the 
day after the release of the full year results and the period 
from 1 July to 12 noon the day after the release of the half 
year results:

 ¸ Trading Window – the period of four weeks commencing 

at 12 noon the day after:

 · The release of the half year results;

 · The release of the full year results; and

 · The Oil Search Annual Meeting.

The Board may also approve trading windows at other times 
of the year.

Table 1 summarises the times at which employees can trade in 
Oil Search shares.

Regardless of the trading times specified in the above table, 
employees and contractors are not permitted to trade at 
any time if they are in possession of inside information. 
Employees are also prohibited from hedging or acquiring 
options over unvested securities, granted under employee 
share plans, at any time. Regular audits of share trading are 
conducted by the Group Secretary to ensure compliance. 

Effective from 1 January 2018 the Company introduced a 
Minimum Shareholding Policy to increase alignment with the 
interests of Oil Search shareholders by imposing a requirement 
that Non-Executive Directors and Executive Key Management 
Personnel build over time, and then maintain, a Minimum 
Shareholding of Oil Search shares.

The Minimum Shareholding is set as a fixed number of 
Oil Search shares. This fixed number will be reviewed from 
time to time by the Board. 

The Minimum Shareholding is calculated by reference to 
the Oil Search share price and (i) the annual base fee received 
by Non-Executive Directors, (ii) the annual Total Fixed 
Remuneration for the Managing Director and (iii) half of the 
average annual Total Fixed Remuneration for the Executive 
General Managers.

Table 2 summarises the current applicable Minimum 
Shareholding required under this Policy.

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT

The Committee must comprise at least three non-executive 
directors.

The members of the Committee during 2018 were:

 ¸ Dr A Kantsler – independent non-executive (Chair from 

1 January 2018)

 ¸ Sir KG Constantinou OBE – independent non-executive

 ¸ Ms FE Harris – independent non-executive 

 ¸ Sir MP Togolo – independent non-executive

 ¸ Ms SM Cunningham – independent non-executive 

(from 26 March 2018)

In addition to the above, Ms M Johns served as an Independent 
Member of the Committee until 30 September 2018. Effective 
from 1 October 2018, Mr Richard Kuna and Mr Desmond 
Yaninen were appointed as Independent Members of the 
Committee. While not a member of the Board, an Independent 
Member is expected to contribute fully to the effective 
functioning and execution of duties and responsibilities of 
the relevant Board committees. The motivation for these 
appointments is twofold; to draw on the experiences and 
capabilities of highly talented PNG citizens as the Company 
continues to invest for the future in PNG, and as equally 
important, to provide the appointees with the unique 
opportunity to experience and participate in governance 
processes of PNG’s largest and most successful listed company. 
This is aligned with Oil Search’s aim of enhancing the pool of 
capable, well-rounded business leaders in PNG.

At the Committee’s invitation, the Managing Director, Executive 
General Manager Human Resources, and Head of Rewards 
attend meetings in an advisory capacity and co-ordinate the 
work of external, independent advisors as requested. All 
executives are excluded from any discussions impacting their 
own remuneration. 

Under its Charter, the Committee must meet at least four times 
a year. The Committee formally met four times during 2018 and 
the Committee Members’ attendance records are disclosed in 
the Directors’ Report. A copy of the charter of the Committee is 
available on Oil Search’s website in the Corporate Governance 
section. The committee also met informally on a number of 
occasions to progress issues on foot and consider other matters 
as they arose.

To ensure it remains up to date with market practice, the 
Committee engages independent external advisors from 
time to time. Table 3 summarises remuneration-related work 
undertaken by external consultants at the Committee’s request 
in 2018 and also notes additional work undertaken by the 
same consultants on behalf of management. While none of the 
Committee’s engagements were for work which constituted 
Remuneration Recommendations for the purposes of the 
Australian Corporations Act 2001, findings were reported 
directly to the Committee or the Board.

Non-Executive Directors do not participate in the Company’s 
Long Term Incentive schemes and must establish their holding 
by acquiring shares on market. 

For the Managing Director and Executive General Managers, 
the Policy operates by restricting the disposal of relevant Oil 
Search Shares acquired under the Company’s Long Term 
Incentive schemes. It does not require the Managing Director 
or Executive General Managers to whom it applies to “top-up” 
the minimum holding threshold by buying Oil Search shares 
on market.

Exceptions to the Policy are permitted (i) if approved by the 
Board (or its delegate) at its sole discretion or (ii) to the extent 
that a disposal is reasonably necessary to enable statutory 
obligations (for example relating to tax) to be met arising from 
the operation of an Oil Search equity-based incentive scheme. 
All Oil Search shares held by the individual will count towards 
the satisfaction of the Minimum Shareholding threshold 
including shares owned through a trust or superannuation 
fund or otherwise held for the benefit of the individual. 

3. 

 ROLE OF THE PEOPLE AND 
NOMINATIONS COMMITTEE 

The People and Nominations Committee (the Committee) 
provides advice and recommendations to the Board regarding 
people matters.

REMUNERATION STRUCTURE 

4. 
Oil Search’s remuneration structure comprises four elements: 

 ¸ Total Fixed Remuneration (TFR);

 ¸ Short-Term Incentive (STI);

 ¸ Long-Term Incentive (LTI); and

 ¸ Occasional Retention Awards of Restricted Shares for 

key/critical staff. 

The mix of remuneration elements for individual employees 
is dependent on their level and role within Oil Search, with 
the proportion of “at risk” performance-related remuneration 
(STI and LTI elements) increasing with greater seniority. 

Chart 1 – Aggregate Managing Director Realised 
Remuneration (non-Statutory) over the cycle
Chart 1 shows the aggregate indexed value of realised 
remuneration outcomes over the ten year period 2009 to 2018 
for the Managing Director. Short and Long Term Incentive 
outcomes have been calculated using the current framework for 
all years to provide consistency of analysis and show the value 
ultimately received in respect of a year, being the aggregate of:

 ¸ TFR (indexed to 100)

 ¸ Cash STI: Cash STI paid in relation to the year (based on 
Target STI multiplied by the STI scorecard outcome for 
the year, with 50% of the resulting STI amount being paid 
in cash);

 ¸ Deferred STI: The value of the Deferred STI ultimately 

received (the 50% deferred STI amount as adjusted for 
movements in the Oil Search share price between award 
and vesting); and

 ¸ Performance Rights: Value of the Performance Rights 
ultimately received in respect of the year, taking 
into account the amount of awards which ultimately 
vested based on the TSR performance condition and 
the movement in the Oil Search share price between 
award and vesting.

Chart 1 shows how the aggregate remuneration outcomes for 
the Managing Director have varied over time as result of the 
combined operation of the Short Term Incentive scorecard 
(which is tightly linked to the long term strategic plan, coupled 
with the significant 50% equity deferral arrangement) and the 
Total Shareholder Return performance conditions attaching to 
the Long Term Incentive awards.

Total Fixed Remuneration (TFR) 
The target ranges for TFR payable for roles in the organisation, 
including those for Executive Key Management Personnel are 
80% – 120% of competitive benchmarks. An independent 
external remuneration consultant is engaged by the Committee 
from time to time to provide competitive benchmark data for 
Executive Key Management Personnel roles. 

For other roles in the organisation, remuneration information 
is derived from relevant remuneration surveys conducted by 
independent third parties. 

An annual TFR review budget, agreed by the Board each year, 
is used to adjust TFRs paid to individuals to ensure that their 
fixed remuneration remains competitive for their specific skills, 
competence, and value to the Company. 

Short-Term Incentive (STI) 
Each permanent employee has the opportunity to earn an 
annual STI which is based on a percentage of his or her TFR. 
The STI percentage increases with seniority to ensure a higher 
proportion of remuneration is “at risk” for senior employees. 

The size of the STI pool is directly related to corporate 
performance through a scorecard which includes a range of key 
measures that directly affect Shareholder Value and which are 
directly linked to the Oil Search Strategic Plan. 

At the start of each year, the Board determines the hurdles and 
target levels of performance which form the STI scorecard. 

At the end of the year, the Board approves an overall STI pool 
based on the level of achievement against the hurdles that were 
determined at the start of the year. 

The STI pool is then distributed to employees taking 
into account: 

 ¸ The contribution of the employee’s division to the 
achievement of the organisational objectives; and

 ¸ The individual performance of the employee. 

96

 OIL SEARCH ANNUAL REPORT 2018 
 
 
 
 
 
DIRECTORS’ REPORT
R emu n eratio n R ep o r t

The target levels of performance set by the Board are 
challenging and are driven by the annual budget and longer 
term strategic plan including resource replacement objectives. 
Achievement of target levels of performance delivers the 
payment of 50% of STI Opportunity. 

The Board has discretion, having regard to recommendations 
from the People and Nominations Committee, to adjust the final 
size of the STI pool after due consideration of the Oil Search 
business performance and scorecard outcomes, including 
clawing back previous awards where appropriate.

The overall STI pool available to all employees is capped at 
100% of the STI Opportunity amount (i.e. 2 x the aggregate 
of STI Target amounts).

Achievement for the Production measure was between 
threshold and target. Target levels of Production for STI 
scorecard purposes were based on the 2018 budget approved 
by the Board prior to the earthquake. These targets were not 
adjusted to reflect periods of deferred production arising from 
the earthquake. Oil Search operated production was below the 
threshold performance against the original scorecard target 
and PNG LNG performance was slightly ahead of threshold 
performance. Actual production for 2018 was above the revised 
operational production targets which were set in April and then 
July as the outcomes from the recovery became clearer, but as 
noted above the targets for STI purposes were not adjusted.

Achievement of the Costs measure was overall close to target. 
This comprised a much better than target outcome for costs 
associated with Oil Search operated assets being under budget 
due to reprioritisation of work programs following the earthquake 
and abnormal costs being offset by insurance recoveries. Costs 
associated with non-operated assets were above budget.

Achievement of the EBITDAX measure was between target and 
stretch. Higher realised hydrocarbon prices more than offset the 
earthquake impacted production outcomes.

Achievement on the Gas Resource discovery measure was 
beyond stretch. This was a result of major resource revisions 
(described in the year-end reserve and resource statement) 
relating to P’nyang and Kimu following successful appraisal 
drilling. Under the phased approach to recognising resource 
additions for Short Term Incentive purposes, the outcome also 
included carried forward recognition of a proportion of the 
PNG LNG gas recertification outcome from 2016.

Achievement on the Oil Resource discovery measure was 
beyond stretch. This was largely a result of the major new oil 
resource addition associated with the Alaska North Slope farm-
in. No part of this was recognised in the 2017 scorecard as the 
transaction was still subject to approval by the Committee on 
Foreign Investment in the US at 2017 year end. This approval was 
received in February 2018 and Oil Search assumed operatorship 
in March 2018. 

Achievement on the strategic and growth initiatives was at 
stretch reflecting achievement of key milestones in earthquake 
return to service objectives, resumption of reliable gas export to 
PNGLNG, Alaska North Slope deal closure, Alaska pre-requisites 
to execute winter drilling program, diversity & inclusion, climate 
change and enterprise wide systems implementation.

The STI scorecard outcome was beyond the stretch outcome 
and under the terms of the scheme the overall outcome was 
therefore capped at 100% of opportunity. The Board has an 
established track record of applying discretion to the overall 
scorecard result to ensure it considers factors not anticipated 
at the start of the year and that the interests of shareholders 
and employees are appropriately aligned and balanced. 
Reflecting the extraordinary events of 2018, and to ensure STI 
outcomes considered both shareholder experience as well 
as the significant efforts of the company in response to the 
earthquake, the Board resolved to exercise its discretion and 
make two further adjustments to the size of the final STI pool 
available for distribution. 

Firstly, an adjustment was made to acknowledge that 
shareholders had experienced circa two months of lost 
2018 production. The Board acknowledges that while this is 
deferred production which will occur in later years, the deferred 
opportunity occurred during a period of high hydrocarbon 
prices relative to recent years and the STI outcome should 
be reduced to reflect that. Balancing that adjustment, the 
Board also acknowledges that Oil Search employees were 
considerably stretched to recover operations from the impacts 
of the earthquake, and field-based staff who remained 
on site immediately thereafter had to endure numerous 
aftershocks and basic living conditions whilst reconstructing 
accommodation facilities, restoring power and adequate 
supplies of potable water. The entire organisation worked 
with a singular focus to return to business as usual as quickly as 
possible. Significantly, not one recordable injury was recorded 
during the restoration of services and production. The 
business outcomes achieved in 2018 reflect the dedication and 
commitment of all staff.

Balancing the above, the Board resolved to apply its 
discretion to reduce the overall STI outcome for 2018 to 92% 
of Opportunity.

Opportunity over the five year period 2014 to 2018.

Incentives – Executives 

Performance Rights
For Executive Key Management Personnel, and other senior 
managers, the Long Term Incentive Plan (LTIP) is provided in 
the form of a grant of Performance Rights (PRs). 

Awards of PRs under the LTIP are rights to acquire ordinary 
shares in the Company for nil consideration, conditional on 
the achievement of pre-determined corporate performance 
hurdles within defined time restrictions. 

The performance criteria for the vesting of PRs are based on 
the Company’s Total Shareholder Return (TSR) over a three-year 
performance period against two peer groups:

 ¸ The ASX50 (excluding property trusts and non-standard 

listings); and

 ¸ The constituents of the Standard & Poor’s Global 1200 

Energy Index (S&P Global 1200 Energy Index). 

For awards made between 2012 and 2016, half of each award 
of PRs was tested against each peer group.

Following a review of the measures in late 2016, the Board 
increased the proportion of the LTI tested against the S&P 
Global 1200 Energy Index from one half to two thirds. 
This change applied prospectively to new awards made from 
2017 onwards. In part, this change recognised the Company’s 
changing shareholder base, which has become increasingly 
international. The remaining one third of awards continues to 
be measured against the constituents of the ASX50, retaining 
alignment of a component executive rewards to Oil Search’s 
performance relative to large Australian listed companies.

To reduce the impact of foreign currency movements on 
the vesting calculations, half of the award tested against the 
international peer group is measured based on Oil Search’s 
and other companies’ TSR in a common currency (USD) and 
the other half in the local currency of the country of primary 
listing (which for Oil Search is Australia). Reducing the impact of 
foreign currency movements increases executives’ perceived 
value of the long term incentives by de-emphasising the 
importance of foreign currency movements on the outcome, 
as such movements are beyond the control of executives. 
No changes were made to the method of calculation of TSR 
outcomes for any prior year awards.

To determine the number of awards vesting, the Company’s 
TSR over the performance period is ranked as follows:

 ¸ as regards one third of the award, against the TSR of each 
of the constituents of the S&P/ASX50 Index (excluding 
property trusts and non-standard listings) as at the 
commencement of the three-year performance period; and

 ¸ as regards one third of the award, against the TSR of each of 
the constituents of the S&P Global 1200 Energy Index at the 
commencement of the three-year performance period. TSR 
outcomes for this part of the award are measured in a US 
dollar base for Oil Search and each constituent company; 
and

98

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
R emu n eratio n R ep o r t

 ¸ as regards the final third of the award, against the TSR of 
each of the constituents of the S&P Global 1200 Energy 
Index at the commencement of the three-year performance 
period. TSR outcomes for this part of the award are 
measured in the local currency of the country of main listing 
for Oil Search and each constituent company.

If, in regard to each part of the award described above, the 
Company’s TSR performance is:

 ¸ below the median, that is, the 50th percentile, the number 

of PRs comprising that part of the award that vest will be zero;

 ¸ at median, the number of PRs that vest will be 50% of the 

total number of PRs comprised in that part of the award;

 ¸ greater than median and less than the 75th percentile, the 
number of PRs that vest will increase on a straight line basis 
from 50% to 100% of the total number of PRs comprised in 
that part of the award; or

 ¸ equal to or greater than the 75th percentile, the number 
of PRs that vest will be 100% of the total number of PRs 
comprised in that part of the award.

This is illustrated in Chart 3.

Oil Search’s TSR performance is required to be at or above

(1)  TSR outcomes against the S&P Global 1200 Energy Index peer group were measured in US dollars for awards up the 2016 Performance Rights awards. For the 

2017 Performance Rights onwards, TSR outcomes are measured half in US dollar and half in local currencies.

(2)  While the 2016 Performance Rights would not have vested until May 2019, Oil Search’s relative TSR for the period 1 January 2016 to 31 December 2018 against 
the comparator groups has been calculated by the independent external consultant. Performance against each group was below the median and as a result no 
awards vested.

Deferred STI
The 50% deferred portion of an executive’s STI (see section 6 below) is awarded as Restricted Shares under the LTIP. Any dividends 
payable on Restricted Shares issued as the deferred component of an executive’s STI award are paid to the executive.

Long Term Incentives – General Employee Share Plan

Each permanent employee can participate in the Oil Search Long Term Incentive Plan if they have demonstrated an acceptable level 
of personal performance.

Share Rights
Share Rights (SRs) are rights to receive Oil Search shares at the end of the three year vesting period subject to continued 
employment at the vesting date. The number of SRs, and therefore the number of shares which will be delivered on the vesting date, 
is determined at the grant date. 

Table 6 contains details of the Share Rights awards made under the general employee share plan between 2014 and 2018.

Retention Awards of Restricted Shares 
In order to assist the Company in retaining key executives and other employees, the Company may issue Restricted Shares. 
Restricted Shares issued only vest after the employee has completed a specified period of future service with the Company. 

Restricted Shares are held on behalf of participants in trust, subject to disposal restrictions and forfeiture conditions, until released 
under the terms of the Plan. 

Retention awards are only made where the Board determines that a significant retention risk exists. In certain cases for senior new 
hires, awards of Restricted Shares are made in lieu of equity forgone with previous employers.

The vesting of Restricted Shares is subject to continued employment only and as such no additional performance conditions apply. 
Unless the Board otherwise determines, unvested Restricted Shares will be forfeited when a participant ceases employment before 
the vesting date.

Short Term Incentive 
The Short Term Incentive (STI) provides an incentive opportunity 
of 100% of TFR for senior executives and 180% of TFR for the 
Managing Director. 

The target payout under the STI provides for a payment of 50% 
of the incentive opportunity. Half of the STI outcome is deferred 
in to Restricted Shares vesting two years after the end of the 
performance period to which the STI relates. 

Table 7 summarises STI awards as a % of TFR for Senior 
Executives and the Managing Director for a range STI outcomes.

‘Opportunity’

Individual awards above ‘Opportunity’ are possible in 
exceptional circumstances with the maximum STI outcome 
possible being capped at 200% of TFR. The overall STI pool is 
capped at 200% of the target amount.

The STI is awarded in March each year for performance in the 
previous calendar year. 

Following the end of the financial year, the Board approves 
an overall STI pool for executives based on the level of 
achievement against the hurdles that were determined at the 
start of the year. This pool is distributed to individual senior 
executives based on their individual performance. 

For all senior executives, 50% of their STI award is paid in cash 
and the other 50% is converted to Restricted Shares under the 
LTIP. The Restricted Shares are held in Trust on behalf of the 
employee and vest on 1 January two years after the end of the 
performance period to which the award relates, providing the 
executive remains employed with Oil Search. Any dividends 
payable on Restricted Shares issued as the deferred component 
of an executive’s STI award are paid to the executive.

Table 8 shows the STI outcomes for the Managing Director and 
Senior Executives since 2014 expressed as a percentage of 
Total Fixed Remuneration. 

Restricted Shares held in trust (whether vested or not) will be 
forfeited by participants who are considered by the Board to 
have acted fraudulently or dishonestly. Once a participant’s 
Restricted Shares have vested, disposal restrictions and 
forfeiture conditions will cease and the Restricted Shares 
will be released from the trust. 

Restricted Shares provided as retention awards do not attract 
voting rights or dividends. 

Long Term Incentive Plan Rules
Under the LTIP, all grants are automatically exercised on vesting. 
All unvested awards lapse on termination of employment unless 
the Board determines otherwise.

The Company may use newly issued or existing shares 
(for example, through purchase on market) to satisfy awards. 

5. 

 REMUNERATION OF KEY  
MANAGEMENT PERSONNEL 

Remuneration for Executive Key Management Personnel 
is benchmarked against that of similar roles in a primary 
reference group of ASX companies of similar size to Oil Search 
in terms of Enterprise Value, Total Assets, Gross Revenue, 
and Net Profit after Tax. For certain roles remuneration may 
also be benchmarked at different management tiers of much 
larger entities to normalise for relative business size while 
reflecting the likely recruitment market for roles. A smaller and 
secondary reference group of international energy and mining 
companies is used to assess whether any particular positions 
for which incumbents may be sourced internationally warrant 
extra consideration. 

Total Fixed Remuneration (TFR)
TFR, which includes Company superannuation contributions 
and other remunerative benefits, is targeted within the range 
of the median and the 62.5 percentile of the reference group, 
depending on the international marketability and mobility of the 
executive concerned. Executives may choose to salary package 
items such as motor vehicles or superannuation contributions. 
However, any costs arising from Fringe Benefits Tax (FBT) on 
salary package items are borne by the executive. 

At Risk Remuneration & Relationship to Company 
Performance 
As noted above in section 4, Oil Search executives are eligible 
to receive a STI and participate in a LTI program which is “at risk” 
remuneration, with any payment dependent on performance. 
The Board’s objective is that the size of these incentives should 
reflect Oil Search’s success in creating Shareholder Value, whilst 
also being competitively positioned against benchmarks based 
on the reference groups of companies mentioned above. 

Accordingly, the size of the STI is directly related to corporate 
performance against a range of key measures that impact 
shareholder value, namely operational metrics (safety, 
production, costs, and development initiatives) and growth 
metrics (the discovery or acquisition of new hydrocarbon 
resources and achievement of tangible value adding milestones 
towards commercialisation of significant oil or gas volumes). 

Similarly, the proportion of Performance Rights grants which 
vest is directly related to Oil Search’s Total Shareholder Return 
relative to peer groups of companies.

Long Term Incentive (LTI) – Performance Rights 
For 2018 the number of Performance Rights granted for the Managing Director and other senior executives was based on the 
following formula:

X% of TFR

Oil Search Share Price

where X is 100% for the Managing Director and 60% for other senior executives, and “Oil Search Share Price” was the Volume 
Weighted Average Price of Oil Search shares for the 5 trading days following the release of 2017 annual results.

(1)  The vesting date of the 2016 Performance Rights is 18 May 2019. As described above, Oil Search’s TSR for the period 1 January 2016 to 31 December 2018 will 

result in 0% vesting.

(2)  Mr Drew was appointed to an Executive General Manager position effective 19 October 2016. The Performance Rights detailed above for 2016 were allocated 

based on the framework applying to his previous, non-Executive General Manager level, position.

(3)  Ms White was appointed to an Executive General Manager position effective 1 May 2017. The Performance Rights detailed above for 2017 were allocated based 

on a pro-rata basis using the frameworks applying to her positions during the year. 

LNG Expansion Incentive
The LNG Expansion Incentive is a separate incentive for the achievement of investment sanction for the Papua LNG development project 
and the PNG LNG expansion project (“the Projects”). Oil Search’s participation in the next phase of LNG development in PNG through the 
Projects provides transformative opportunities that will have a material impact on company value and sustainability. 

Ensuring successful co-operation between stakeholders in the Projects is contingent on a highly complex alignment of commitments and 
assessments requiring the combined financial, engineering, geoscientific, and stakeholder engagement expertise of the current Oil Search 
executive team for a successful outcome. In addition to these transformative and material opportunities, the company’s executives are 
expected to deliver on key operational objectives critical to the everyday operations of Oil Search. 

This has presented the Board with a number of significant issues from the perspective of strategic and operational risk, performance 
management and remuneration:

 ¸ Oil Search’s management team have the skills and operational experience with local PNG issues for the coordinated 

management and achievement of investment sanction for these highly complex and transformative Projects; 

 ¸ The materiality of reward for the Projects within the current STI scorecard and incentive framework does not reflect the 

materiality of the LNG expansion opportunities;

102

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
R emu n eratio n R ep o r t

 ¸  Increasing the weighting of the Projects within the existing scorecard reward system would dilute the importance of operational 

objectives beyond their ongoing importance; and

 ¸  The timing of investment sanction and implementation of the Projects does not fit well within the current annual STI and LTI 

periods, and is itself a key driver of value.

The Board has considered these strategic and operational risks and determined to implement a separate LNG Expansion Incentive 
Plan that will:

 ¸ Match the materiality of reward with the materiality of achieving both operational objectives and achieving investment sanction 

for the Projects;

 ¸ Focus executives on achieving both operational and transformative objectives; and

 ¸ Increase the probability that key executives remain with the project for the near to mid-term.

The participants in the LNG Expansion Incentive Plan are the Managing Director and his Executive direct reports, being the 
members of the management team who are critical to a successful achievement of investment sanction for the Projects.

The LNG Expansion Incentive Plan has been structured in a way that will minimise the risks and optimise outcomes for shareholders. 

 ¸ 25% of the LNG Expansion Incentive is paid as cash and is contingent on the achievement of scorecard objectives that are 
essential pre-requisites for achieving investment sanction for the Projects. The level of achievement of this tranche will be 
determined at the time KPIs are achieved; and

 ¸ 75% of the LNG Expansion Incentive will be granted as Share Rights. Vesting will be contingent on achieving investment 

sanction for the Projects within a defined period, and continuing service (subject to good leaver provisions) with a vesting 
period that ends two years after investment sanction is achieved (provided that date is before a certain date determined by the 
Board).

The deferred Share Rights and the cash component of the LNG Expansion Incentive are at risk and subject to the achievement of:

 ¸ A scorecard of pre-requisites that are necessary to achieve investment sanction for the Projects;

 ¸ Investment sanction for the Projects to be achieved before a certain date; and

 ¸ Continuing employment with the Group (or otherwise a good leaver).

A total of 500,935 Share Rights were granted on 21 June 2018

There is a scorecard of pre-requisite objectives that are critical to achieving investment sanction to proceed with the Projects. 
These objectives are separate and distinct from the scorecard objectives for the existing STI. Since the LNG Expansion Incentive 
Plan scorecard objectives are commercially sensitive the Board intends to provide details of the extent to which targets were set 
and objectives achieved in the company’s remuneration report for the year in which the objectives are to be tested and the cash 
incentive, if any, awarded. However, the Board has taken care to ensure the LNG Expansion Incentive Plan scorecard objectives are 
specifically measurable and focussed on the following areas:

 ¸ Certification of project reserves
 ¸ Obtaining required project licences

In addition to the above, the Board will also consider the contribution Oil Search makes in relation to supporting in-country 
engagement with other stakeholders including Government and Landowners.

103

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
R emu n eratio n R ep o r t

The timing of investment sanction for the Projects is critical to the timing of the first LNG cargoes and cash flows, and consequently, 
Net Present Value (NPV). The Board has made an allowance for a complex set of other factors that could optimise NPV, but slightly 
delay investment sanction of either Project. Nevertheless, the Board want to impress upon management that investment sanction 
beyond a certain date will not result in any additional reward. As this time to achieve investment sanction is commercially sensitive, it 
will be disclosed after investment sanction is achieved.

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT

Realised Remuneration of Executive Key Management Personnel Remuneration (Australian Dollars)
Table 11 below sets out the ‘Realised Remuneration’ of Executive Key Management Personnel for 2017 and 2018 in Australian 
Dollars. It is included to complement the Statutory Remuneration disclosure and to better illustrate the remuneration received by 
Executives.

As Oil Search benchmarks (and for all but one Executive) pays remuneration in Australian Dollars, it is difficult for the reader to 
distinguish annual movements in fixed remuneration from exchange rate movements in the Statutory Remuneration table. 

In Table 11, Fixed Remuneration represents the level of Base Pay, Superannuation and expatriate allowances paid to the Executive. 
The Cash Short Term Incentive is the cash Short Term Incentive earned to the Executive in respect of the year (even though it is paid 
to the Executive in the March following the year). Deferred STI from Prior Years shows the value on the vesting date of Restricted 
Shares granted in lieu of Deferred Short Term Incentives from two years prior. The Long Term Incentive vesting in the year is the 
value of Performance Rights vesting in the year reflecting (a) the portion of awards which satisfies the Total Shareholder Return 
performance condition and (b) the Oil Search share price on the date of vesting.

While this disclosure is non-statutory it has been audited.

NON-EXECUTIVE DIRECTOR REMUNERATION

Remuneration Policy 
Remuneration for Non-Executive Directors is determined by reference to relevant external market data and takes into consideration 
the level of fees paid to directors of other Australian corporations of similar size and complexity to Oil Search, the scale of its 
international activities and the responsibilities and work requirements of Board members. Remuneration for Non-Executive Directors 
is subject to the aggregate limit of A$2.5 million in any calendar year which was set by shareholders at the 2013 Annual Meeting. 

Remuneration Payable 
Fees payable to Non-Executive Directors are reviewed periodically and are fixed by the Board as discussed above. 

Table 23 sets out the fee structure which has applied since 1 January 2017. 

Table 23 – Annual Board and Committee Fees Payable to Non-Executive Directors in Australian Dollars

Each Non-Executive Director also receives a travel allowance of A$25,500 per annum to compensate for the time spent 
travelling to Papua New Guinea and Australia to attend Board and Committee Meetings and for time spent on field trips to 
the Company’s operations. 

Board fees are paid to Non-Executive Directors only. Mr Gerea Aopi, who was an Executive Director, retired from the Oil Search 
Board effective from 16 March 2018. As an Executive Director, Mr Aopi did not receive Directors’ Fees. A Non-Executive Director 
who does receive fees was appointed to fill the vacancy following Mr Aopi’s retirement. This consumed a substantial portion of the 
remaining fee pool ‘headroom’. A proposal will be brought to the 2019 Annual Meeting to raise the aggregate fee pool available to 
Directors from the current $2.5 million to $3.0 million. This will be the first increase sought since 2013.

 OIL SEARCH ANNUAL REPORT 2018DIRECTORS’ REPORT
R emu n eratio n R ep o r t

In addition to Board and Committee fees, non-executive directors are entitled to be reimbursed for all reasonable travel, 
accommodation and other expenses incurred in attending meetings of the Board, Committees or shareholders or while engaged 
on Oil Search business.

Following an external benchmarking review of Directors Fees, effective from 1 January 2019, the Chair and Main Board fees were 
increased to A$550,000 and A$190,000 respectively to better align with the market median. In additional the Chair fees for the 
Health, Safety and Sustainability Committee and the People & Nominations Committee were increased to the level of the Audit & 
Financial Risk Committee in recognition of the comparable workload and responsibilities of those Chair positions.

There are no provisions in any of the Non-Executive Directors’ appointment arrangements for compensation payable on early 
termination of their directorship.

There is no separate retirement benefits plan or provision for superannuation for Oil Search’s non-executive directors.

Details of Directors’ Remuneration 
Table 24 outlines the remuneration received by Oil Search Limited directors in 2017 and 2018.

The Managing Director, Mr Botten is the only executive director on the Board.

 OIL SEARCH ANNUAL REPORT 2018NOTES TO THE FINANCIAL STATEMENTS

SIGNIFICANT ACCOUNTING POLICIES

1 
Oil Search Limited (the ‘parent entity’ or ‘Company’) is 
incorporated in Papua New Guinea (PNG). The consolidated 
financial report for the year ended 31 December 2018 
comprises the parent entity and its controlled entities 
(together, ‘the Group’).

The financial statements were authorised for issue by the Board 
of Directors on 18 February 2019.

 Basis of preparation

(a) 
The financial statements have been prepared in accordance 
with International Financial Reporting Standards (IFRS), 
International Financial Reporting Interpretations Committee 
(“IFRIC”) interpretations and the PNG Companies Act 1997. 
The financial statements have been prepared under the 
historical cost convention.

(i) 

Issued standards adopted during year

The Group has adopted all of the new and revised standards 
and interpretations issued by the International Accounting 
Standards Board (IASB) that are mandatorily effective for 
accounting periods that begin on or after 1 January 2018. 
The introduction of new or amended standards required the 
Group to amend its accounting policies for the following: 

 ¸  IFRS 9 Financial Instruments; and 

 ¸  IFRS 15 Revenue from Contracts with Customers. 

There were no retrospective adjustments required as a 
result of adopting the above standards. The other new or 
amended standards did not have any impact on the Group’s 
accounting policies. 

There have been no other new standards or amendments 
that were mandatory for adoption for the year ended 
31 December 2018. 

(ii) 

New accounting standards not yet effective

The following new accounting standards are not yet effective 
but may have an impact on the Group in the financial years 
commencing 1 January 2019 or later:

 ¸ IFRS 16 Leases – effective 1 January 2019

IFRS 16 Leases supersedes existing accounting guidance 
contained under IAS 17 Leases and IFRIC 4 Determining 
whether an Arrangement contains a Lease and related 
interpretations. IFRS 16 provides a single lessee accounting 
model requiring lessees to recognise assets and liabilities 
for all leases unless the lease term is 12 months or less or the 
underlying asset has a low value. Lessors continue to classify 
leases as operating or finance, with IFRS 16’s approach 
to lessor accounting substantially unchanged from its 
predecessor, IAS 17. New disclosure requirements have 
also been introduced under the new standard.

IFRS 16 is effective for annual reporting periods commencing 
on or after 1 January 2019, making it effective for the Group’s 
half year financial statements ending 30 June 2019. 

The Group has conducted a comprehensive review, of all 
relevant company contracts and contracts in joint operations 
operated by others. 

The Group will apply the standard from its mandatory adoption 
date of 1 January 2019. The Group intends to apply the 
simplified transition approach and will not restate comparative 
amounts. Right-of-use assets will be measured on transition as if 
the new Standard had been applied since the commencement 
date of the lease. The lease liability will be measured at the date 
of adoption. 

As at reporting date, the Group has non-cancellable 
operating lease commitments of $305 million. The Group 
expects to recognise right of use assets of approximately 
$230.7 million, lease liabilities of approximately $281.3 million 
and an adjustment reducing opening retained earnings by 
approximately $24.9 million. 

As a result of the transition the Group expects the following pre-
tax changes to be reflected in its statement of comprehensive 
income based on leases identified at 31 December 2018:

 ¸  an increase of approximately $20-22 million in net finance 

costs and $23-25 million in depreciation charges;

 ¸ a reduction of rental expense of approximately 

$10-12 million; and 

 ¸ an increase in other income of approximately 

$25-27 million. 

The transition to IFRS 16 requires the Group to make certain 
policy choices and elections for various available practical 
expedients and transitional reliefs. The Group will adopt the 
following policy and practical expedients:

 ¸ The Group has opted not to apply IFRS 16 to leases of 

intangible assets. 

 ¸ The Group has opted not to apply IFRS 16 to low value items 
of under $5,000 and leases with a term of 12 months or less. 

 ¸ The Group will separate lease and non-lease components 
from arrangements and account for these separately.

 ¸ The Group will not apply IFRS 16 to a portfolio of similar 

leases and will account for each lease separately. 

Principles of consolidation

(b) 
The consolidated financial statements comprise the financial 
statements of Oil Search Limited and its controlled subsidiaries, 
after elimination of all inter-company transactions.

Business combinations

(i) 
The Group accounts for business combinations using the 
acquisition method when control is transferred to the Group. 
The consideration transferred in the acquisition is generally 
measured at fair value, as are the identifiable net assets acquired. 
Any goodwill that arises is tested annually for impairment. 
Any gain on a bargain purchase is recognised in profit or loss 
immediately. Transaction costs are expensed as incurred, except 
if related to the issue of debt or equity securities.

The consideration transferred does not include amounts related 
to the settlement of pre-existing relationships. Such amounts 
are generally recognised in profit or loss.

124

 OIL SEARCH ANNUAL REPORT 2018 
NOTES TO THE FINANCIAL STATEMENTS

1 

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Any contingent consideration payable is measured at fair 
value at the acquisition date. If the contingent consideration is 
classified as equity, then it is not remeasured and settlement is 
accounted for within equity. Otherwise, subsequent changes in 
the fair value of the contingent consideration are recognised in 
profit or loss.

Subsidiaries

(ii) 
Subsidiaries are entities controlled by the Group. The Group 
controls an entity when it is exposed to, or has rights to, 
variable returns from its involvement with the entity and has the 
ability to affect those returns through its power over the entity. 
The financial statements of subsidiaries are included in the 
consolidated financial statements from the date on which control 
commences until the date on which control ceases. The financial 
statements of subsidiaries are prepared for the same reporting 
period as the parent entity, using consistent accounting policies.

Joint arrangements

(iii) 
Exploration, development and production activities of the 
Group are primarily carried on through joint arrangements 
with other parties. Joint arrangements are classified as either 
joint operations or joint ventures depending on the contractual 
rights and obligations each investor has, rather than the legal 
structure of the joint arrangement. The Group has assessed 
the nature of its joint arrangements and determined that they 
comprise investments in joint operations.

Joint operations
The Group has accounted for its direct rights and obligations  
by recognising its share of jointly held assets, liabilities, revenues 
and expenses of each joint operation. These have been 
incorporated in the financial statements under the appropriate 
headings. Details of the joint operations are set out in note 26.

Joint venture
The Group has accounted for its investments in joint ventures 
under the equity method of accounting with these investments 
initially recognised at cost. The Group’s investment in 
the joint venture, profit and loss and movements in other 
comprehensive income are adjusted to recognise the 
Group’s corresponding share of the post-acquisition profits 
or losses and movements in other comprehensive income 
of the investee. Dividends received or receivable from joint 
ventures are recognised as a reduction in the carrying amount 
of the investment. 

When the Group’s share of losses in an equity-accounted 
investment equals or exceeds its interest in the entity, the 
Group does not recognise further losses, unless it has incurred 
obligations or made payments on behalf of that entity. 

(c) 

Currency translation

Functional and presentation currency

(i) 
Items included in the financial statements of each of the 
Group’s entities are measured using the currency of the primary 
economic environment in which the entity operates (‘the 
functional currency’). The consolidated and parent financial 
statements are presented in United States dollars, which is 
Oil Search Limited’s functional and presentation currency.

125

Transactions and balances

(ii) 
Foreign currency transactions are translated into the functional 
currency using the exchange rates prevailing at the dates of the 
transactions. Foreign exchange gains and losses resulting from 
the settlement of such transactions and from the translation 
at year end exchange rates of monetary assets and liabilities 
denominated in foreign currencies are recognised in profit 
or loss.

Foreign exchange gains and losses that relate to borrowings are 
presented in the statement of comprehensive income, within 
finance costs. All other foreign exchange gains and losses are 
presented in the statement of comprehensive income on a net 
basis within other expenses.

Group companies

(iii) 
The results and financial position of foreign operations (none 
of which has the currency of a hyperinflationary economy) 
thathave a functional currency different from the presentation 
currency are translated into the presentation currency 
as follows:

 ¸  assets and liabilities for each statement of financial position 
presented are translated at the closing rate at the date of 
that statement of financial position;

 ¸  income and expenses for each statement of comprehensive 
income are translated at average exchange rates (unless this 
is not a reasonable approximation of the cumulative effect 
of the rates prevailing on the transaction dates, in which 
case income and expenses are translated at the dates of the 
transactions); and

 ¸  all resulting exchange differences are recognised in other 

comprehensive income.

Revenue recognition

(d) 
Revenue is recognised when the performance obligation 
is satisfied by transferring a promised good or service to a 
customer. An asset or service is transferred when the customer 
obtains control of that asset or service. When a performance 
obligation is satisfied, the amount of revenue recognised is 
the amount of the transaction price that is allocated to that 
performance obligation. Where part or all of the transaction 
price is variable, revenue is recognised only to the extent that it 
is highly probable that a significant reversal of revenue will not 
occur. Revenue for the Group’s main products is recognised 
as follows:

Liquefied natural gas 
Performance obligations are satisfied when the control of LNG 
is transferred to the customer when the product is loaded 
on board the offtake vessel or offloaded from the vessel, 
depending on the contractual terms of the cargo. Sales 
made under long term contracts are subject to take or pay 
arrangements and represent the delivery of a series of distinct 
but substantially the same goods consecutively over a period 
of time. A contract liability may arise under these contracts if 
delivered quantities are less than contracted quantities.

 OIL SEARCH ANNUAL REPORT 2018NOTES TO THE FINANCIAL STATEMENTS

1 

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The initial transaction price for LNG sales is calculated using a 
provisional price at the date the customer takes control of the 
product. The difference between the provisional and the final 
transaction price is recognised at the point when the final price 
is determined. 

estimates of the number of awards that are expected to vest. 
It recognises the impact of the revision of original estimates, 
if any, in the statement of comprehensive income, and a 
corresponding adjustment to equity over the remaining 
vesting period. 

Credit terms for LNG sales are between 8-10 days. 

Oil and condensate

Performance obligations are satisfied when the control of oil 
and condensate is transferred to the customer at the despatch 
point to the offtake vessel. The transaction price for oil and 
condensate sales may not be finalised at the date the customer 
takes control of the product. In such cases, a provisional 
transaction price is used until a final transaction price can be 
determined. The difference between the provisional and the 
final transaction price is recognised at the point when the final 
price is determined. 

Credit terms for crude and condensate cargoes are 30 days.

Gas
Performance obligations are satisfied when control of the gas 
is transferred to the customer at the gas delivery point. 

Credit terms are between 20-30 days.

Dividend income
Dividend income from controlled entities is recognised as other 
income in the statement of comprehensive income when the 
dividends are declared, and from other parties as the dividends 
are received or receivable.

Borrowing costs

(e) 
Borrowing costs directly attributable to the acquisition, 
construction or production of qualifying assets, which are 
assets that necessarily take a substantial period of time to get 
ready for their intended use or sale, are added to the cost of 
those assets, until such time as the assets are substantially ready 
for their intended use or sale. The capitalisation rate used to 
determine the amount of borrowing costs to be capitalised is 
the weighted average interest rate applicable to the borrower’s 
outstanding borrowings during the year used to develop the 
qualifying asset.

All other borrowing costs are recognised in the statement of 
comprehensive income in the period in which they are incurred.

Share-based remuneration 

(f) 
The fair value at grant date of equity-settled, share-based 
compensation plans is charged to the statement of 
comprehensive income over the period for which the benefits 
of employee services are to be derived. The corresponding 
accrued employee entitlement is recorded in the employee 
equity compensation reserve. The fair value of the awards is 
calculated using an option pricing model which considers 
a number of factors. Where awards are forfeited because 
non-market vesting conditions are not satisfied, the expense 
previously recognised is proportionately reversed. At each 
statement of financial position date, the entity revises its 

Where shares in Oil Search Limited are acquired by on-market 
purchases prior to settling vested entitlements, the cost of the 
acquired shares is carried as treasury shares and deducted 
from equity. No gain or loss is recognised in the statement 
of comprehensive income on the purchase, sale, issue or 
cancellation of the Group’s own equity instruments.

Income tax

(g) 
The current tax payable or receivable is based on taxable 
profit for the year. Taxable profit differs from net profit as 
reported in the statement of comprehensive income because 
it excludes items of income or expense that are taxable or 
deductible in other years and it further excludes items that are 
never taxable or deductible. The Group’s liability or asset for 
current tax is calculated using tax rates that have been enacted 
or substantively enacted at the reporting date. Deferred tax 
is accounted for using the balance sheet liability method. 
Temporary differences are differences between the tax base 
of an asset or liability and its carrying amount in the statement 
of financial position. The tax base of an asset or liability is the 
amount attributed to that asset or liability for tax purposes.

In principle, deferred tax liabilities are recognised for all taxable 
temporary differences. Deferred tax assets are recognised to 
the extent that it is probable that sufficient taxable amounts will 
be available against which deductible temporary differences 
or unused tax losses and tax offsets can be utilised. However, 
deferred tax assets and liabilities are not recognised if the 
temporary differences giving rise to them arise from initial 
recognition of assets and liabilities (other than as a result of a 
business combination) which affects neither taxable income 
nor accounting profit. Furthermore, a deferred tax liability is not 
recognised in relation to taxable temporary differences arising 
from the initial recognition of goodwill.

The carrying amount of deferred tax assets is reviewed at each 
statement of financial position date and reduced to the extent 
that it is no longer probable that sufficient taxable profit will 
be available to allow all or part of the deferred tax asset to 
be utilised.

Deferred tax assets and liabilities are measured at the tax rates 
that are expected to apply to the period when the asset is 
realised or the liability is settled, based on tax rates (and tax 
laws) that have been enacted or substantively enacted at the 
statement of financial position date. Deferred tax is charged 
or credited in the statement of comprehensive income, except 
when it relates to items charged or credited directly to equity, 
in which case the deferred tax is also dealt with in equity.

Tax benefits transferred between Group companies are 
transferred under normal commercial arrangements, with 
consideration paid equal to the tax benefit of the transfer.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Inventories

(h) 
Inventories are valued at the lower of cost or net realisable 
value. Cost is determined as follows: 

 ¸  materials, which include drilling and maintenance stocks, 

are valued at the cost of acquisition; and

 ¸  petroleum products, comprising extracted crude oil and 
condensate, LNG and refined products stored in tanks, 
pipeline systems and aboard vessels are valued using the 
full absorption cost method. 

Exploration and evaluation assets

(i) 
Exploration and evaluation expenditures are accounted for 
under the successful efforts method. 

Exploration licence acquisition costs are initially capitalised. 
For exploration and appraisal wells, costs directly associated 
with drilling and evaluating the wells are initially capitalised 
pending an assessment of whether economically recoverable 
hydrocarbons have been discovered or whether expenditures 
are expected to be recouped by sale. All other exploration and 
evaluation costs are expensed as incurred.

Capitalised exploration costs are reviewed at each reporting 
date to determine whether there is an indication of impairment, 
generally on a licence-by-licence basis. Impairment 
indicators include:

 ¸ the exploration licence has expired and is not expected 

to be renewed;

 ¸ exploration and appraisal activities have not led to the 

discovery of economically recoverable reserves and no 
further activity on the licence is planned;

 ¸ sufficient information exists to indicate that the carrying 

amount of the exploration and evaluation asset is unlikely to 
be recovered in full from successful development or by sale.

Where such indicators exist, an impairment test is performed – 
see accounting policy (m). 

When an oil or gas field has been approved for development, 
the accumulated exploration and evaluation costs are 
transferred to Oil and Gas Assets – Assets in Development. 

Where an ownership interest in an exploration and evaluation 
asset is exchanged for another, the transaction is recognised by 
reference to the carrying value of the original interest. Any cash 
consideration paid, including transaction costs, is accounted for 
as an acquisition of exploration and evaluation assets. Any cash 
consideration received, net of transaction costs, is treated as 
a recoupment of costs expensed in the relevant year, with any 
excess consideration received accounted for as a reduction 
to the previously capitalised amounts. If the consideration 
received is in excess of current year expense and capitalised 
amounts, the excess is recorded as a gain on disposal of 
non-current assets. 

(j) 

Oil and gas assets

Assets in development
When the technical and commercial feasibility of an 
undeveloped oil or gas field has been demonstrated and 
approval of commercial development occurs, the field 
enters its development phase. The costs of oil and gas 
assets in development are separately accounted for and 
include past exploration and evaluation costs, development 
drilling and other subsurface expenditure, surface plant and 
equipment and any associated land and buildings. When 
the committed development expenditure programs are 
completed and production commences, these costs are 
subject to amortisation.

Producing assets
The costs of oil and gas assets in production include past 
exploration and evaluation costs, past development costs 
and the ongoing costs of continuing to develop reserves 
for production and to expand, replace, acquire or improve 
plant and equipment and any associated land and buildings. 
These costs are subject to amortisation.

Amortisation of oil and gas assets
Amortisation is calculated using the units of production method 
for an asset or group of assets from the date of commencement 
of production. Depletion charges are calculated using the 
units of production method over the life of the estimated 
Developed, Proven plus Probable (“2P”) reserves for an asset 
or group of assets.

Restoration costs
Site restoration costs are capitalised within the cost of the 
associated assets and the provision is stated in the statement of 
financial position at total estimated present value. These costs 
are based on judgements and assumptions regarding removal 
dates, technologies, and industry practice. Over time, the 
liability is increased for the change in the present value based 
on a risk adjusted pre-tax discount rate appropriate to the risks 
inherent in the liability. The costs of restoration are brought to 
account in the statement of comprehensive income through 
depreciation of the associated assets over the economic 
life of the projects with which these costs are associated. 
The unwinding of the discount is recorded as an accretion 
charge within finance costs. 

Other plant and equipment

(k) 
Plant and equipment are carried at cost less accumulated 
depreciation and impairment. Any gain or loss on the disposal 
of assets is determined as the difference between the carrying 
value of the asset at the time of disposal and the proceeds from 
disposal, and is included in the results of the Group in the year 
of disposal.

Depreciation
Depreciation on plant and equipment, excluding rigs, is calculated 
on a straight-line basis so as to generally write-off the cost of each 
fixed asset over its estimated useful life on the following basis:

Marine 
Corporate plant and equipment 

4%
20% – 33%

The depreciation on rigs is computed using drilling days based 
on a ten year drilling ltife. 

(l) 

Leases

Leased assets

(i) 
Assets held by the Group under leases that transfer to the 
Group substantially all the risks and rewards of ownership 
are classified as finance leases. The leased asset is measured 
initially at an amount equal to the lower of its fair value and the 
present value of the minimum lease payments. Subsequent to 
initial recognition, the assets are accounted for in accordance 
with the accounting policy applicable to that asset. Assets held 
under other leases are classified as operating leases and are not 
recognised in the Group’s statement of financial position. 

Lease payments

(ii) 
Payments made under operating leases are recognised in profit 
or loss on a straight-line basis over the term of the lease. Lease 
incentives received are recognised as an integral part of the 
total lease expense, over the term of the lease. 

Minimum lease payments made under finance leases are 
apportioned between the finance expense and the reduction 
of the outstanding liability. The finance expense is allocated to 
each period during the lease term so as to produce a constant 
periodic rate of interest on the remaining balance of the liability.

Impairment of assets

(m) 
The carrying amounts of all assets, other than inventory, certain 
financial assets and deferred tax assets, are reviewed at each 
reporting date to determine whether there is an indication of 
impairment. Where such an indication exists, an estimate of the 
recoverable amount is made. 

For any asset that does not generate largely independent 
cash flows, the recoverable amount is determined for the 
cash generating unit (CGU) to which the asset belongs. 

Expected future cash flows are the basis for determining 
the recoverable amount, however, market values are also 
referenced where appropriate.

An impairment loss is recognised in the statement of 
comprehensive income when the carrying amount of an asset or 
its CGU exceeds its recoverable amount. Where an impairment 
loss subsequently reverses, the carrying amount of the asset 
(or CGU) is increased to the revised estimate of its recoverable 
amount, but only to the extent that the asset’s carrying amount 
does not exceed the carrying amount that would have been 
determined, net of depreciation or amortisation, if no 
impairment loss had been recognised.

128

Employee benefits

(n) 
Provision is made for long service leave and annual leave 
estimated to be payable to employees on the basis of statutory 
and contractual requirements. The liability for long service leave 
and annual leave which is not expected to be settled within 
12 months after the end of the period in which the employees 
render the related service is recognised in the provision for 
employee entitlements and measured as the present value of 
expected future payments to be made in respect of services 
provided by employees up to the end of the reporting period. 
Expected future payments are discounted using market yields 
at the end of the reporting period on government bonds with 
terms and currencies that match, as closely as possible, the 
estimated future cash outflows. 

The obligations are presented as current liabilities in the 
statement of financial position if the entity does not have an 
unconditional right to defer settlement for at least twelve 
months after the reporting date, regardless of when the 
actual settlement is expected to occur.

(o) 

Investments and other financial assets 

Investments

(i) 
Investments in subsidiaries are accounted for at cost in the 
parent entity financial statements.

Other financial assets

(ii) 
All other financial assets are initially recognised at the fair value 
of consideration paid. Subsequently, all financial assets are 
measured at amortised cost or fair value on the basis of the 
entity’s business model for managing the financial assets and 
the contractual cash flow characteristics of the financial assets. 

Financial assets are assessed for indicators of impairment through 
the use of an expected credit loss model. The expected credit 
loss (ECL) model requires the Group to account for expected 
credit losses and changes in those expected credit losses 
at each reporting date to reflect changes in credit risk upon 
initial recognition of the financial assets. In other words, it is not 
necessary for a credit event to have occurred before credit losses 
are recognised.

The Group assesses on a forward-looking basis, the 
expected credit losses associated with its financial assets. 
The loss allowance for a financial instrument is measured at an 
amount equal to the lifetime ECL if the credit risk on that financial 
instrument has increased significantly since initial recognition. 
If the credit risk on a financial instrument has not increased 
significantly since initial recognition, the loss allowance is 
measured for that financial instrument at an amount equal to 
a 12 month ECL horizon. 

A simplified approach is used for measuring the loss allowance 
at an amount equal to lifetime ECL for trade receivables, contract 
assets and lease receivables in certain circumstances. For trade 
receivables, the simplified approach requires expected lifetime 
losses to be recognised from initial recognition of receivables. 
Given the credit quality of the Group’s customers, which are 
investment grade or backed by letters of credit and there has 
been no historical credit loss experience for trade receivables, 
no additional loss allowance was recognised.

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Borrowings 

(p) 
Borrowings are initially recognised at fair value, net of 
transaction costs incurred. Borrowings are subsequently 
measured at amortised cost. Any difference between the 
proceeds (net of transaction costs) and the redemption 
amount is recognised in profit or loss or capitalised against a 
qualifying project over the period of the borrowings using the 
effective interest method. Fees paid on the establishment of 
loan facilities are recognised as transaction costs of the loan 
to the extent that it is probable that some or all of the facility 
will be drawn down. In this case, the fee is deferred until the 
draw down occurs. To the extent there is no evidence that it 
is probable that some or all of the facility will be drawn down, 
the fee is capitalised as a prepayment for liquidity services and 
amortised over the period of the facility to which it relates.

Borrowings are removed from the statement of financial 
position when the obligation specified in the contract is 
discharged, cancelled or expired.

Borrowings are classified as current liabilities unless the Group 
has an unconditional right to defer settlement of the liability for 
at least 12 months after the reporting period.

(q) 
Critical accounting estimates and assumptions 
In applying the Group’s accounting policies, management 
regularly evaluates judgements, estimates and assumptions 
based on experience and other factors, including expectations 
of future events that may have an impact on the Group. 
All judgements, estimates and assumptions made are 
believed to be reasonable based on the most current set of 
circumstances available to management. Actual results may 
differ from those judgements, estimates and assumptions. 
Significant judgements, estimates and assumptions made by 
management in the preparation of these financial statements 
are outlined below.

Impairment of assets
The Group assesses whether oil and gas assets are impaired 
on a semi-annual basis. This requires review of the indicators of 
impairment and/or an estimation of the recoverable amount of 
the cash-generating unit to which the assets belong. For oil and 
gas properties, expected future cash flow estimation is based 
on reserves, future production profiles, commodity prices and 
costs. Market values are also referenced where appropriate. 
The carrying value of oil and gas properties, exploration and 
evaluation and other plant and equipment is disclosed in 
notes 14 to 15.

Restoration obligations
The Group estimates the future removal and restoration costs 
of oil and gas production facilities, wells, pipelines and related 
assets at the time of installation of the assets. In most instances 
the removal of these assets will occur many years in the future. 
The estimates of future removal costs are made considering 
relevant legislation and industry practice and require 
management to make judgments regarding the removal date, 
the extent of restoration activities required and future removal 
technologies. For more detail regarding the policy in respect of 
provision for restoration refer to note 1(j).

The carrying amount of the provision for restoration is disclosed 
in note 17.

Reserve estimates
The estimated reserves are management assessments and 
take into consideration reviews by an independent third party, 
Netherland Sewell and Associates, under the Company’s 
reserves audit program which requires an external audit of 
each material producing field every three years, as well as 
other assumptions, interpretations and assessments. 

These include assumptions regarding commodity prices, 
exchange rates, discount rates, future production and 
transportation costs, and interpretations of geological and 
geophysical models to make assessments of the quality of 
reservoirs and their anticipated recoveries. Changes in reported 
reserves can impact asset carrying values, the provision for 
restoration and the recognition of deferred tax assets, due to 
changes in expected future cash flows. Reserves are integral 
to the amount of depreciation, depletion and amortisation 
charged to the statement of comprehensive income and the 
calculation of inventory. Reserves estimation conforms with 
guidelines prepared by the Society of Petroleum Engineers and 
the Australian Securities Exchange Listing Rules.

Exploration and evaluation
The Group’s policy for exploration and evaluation expenditure 
is discussed in note 1(i). The application of this policy requires 
management to make certain estimates and assumptions as 
to future events and circumstances, particularly in relation to 
the assessment of whether economic quantities of reserves 
have been found. Any such estimates and assumptions 
may change as new information becomes available. If, after 
having capitalised exploration and evaluation expenditure, 
management concludes that the capitalised expenditure is 
unlikely to be recovered by future exploitation or sale, then the 
relevant capitalised amount will be written off to the statement 
of comprehensive income.

The carrying amount of exploration and evaluation assets is 
disclosed in note 14.

Classification of joint arrangements
Exploration, development and production activities of the 
Group are conducted primarily through arrangements with 
other parties. Each arrangement has a contractual agreement 
which provides the participating parties rights to the assets and 
obligations for the liabilities of the arrangement. Under certain 
agreements, more than one combination of participants can 
make decisions about the relevant activities and therefore joint 
control does not exist. Where the arrangement has the same 
legal form as a joint operation but is not subject to joint control, 
the Group accounts for its interest in accordance with the 
contractual agreements by recognising its share of jointly held

SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Deferred taxes
The calculation of the Group’s tax charge involves a degree of 
estimation and judgement in respect of certain items for which 
the ultimate tax determination is uncertain. 

The Group recognises deferred tax assets only to the extent 
that it is probable that future taxable profits will be available 
against which the asset can be utilised.

In making this assessment, a forecast of future taxable profits 
is made, based on revenues, future production profiles, 
commodity prices and costs. Assumptions are also made in 
respect of future tax elections that may be utilised between 
tax ring fences and in respect of the ongoing success of the 
Group’s exploration and appraisal program.

Weighted average number of ordinary shares used for the purposes of calculating diluted earnings per share reconciles to the 
number used to calculate basic earnings per share as follows:

Basic earnings per share

Employee share rights

Employee performance rights

Diluted earnings per share

Basic earnings and diluted earnings per share have been calculated on a net profit after tax of $341.2 million (2017: $302.1 million). 
There are 1,764,126 share rights (2017: 1,504,143) and 3,549,532 performance rights (2017: 3,163,920) which are dilutive potential 
ordinary shares and are therefore included in the weighted average number of shares for the calculation of diluted earnings per 
share. In 2018, the Restricted Share Plan Trust held 4,953 (2017: 347) Oil Search Limited shares that may be used to settle dilutive 
potential ordinary shares which were taken into account in the calculation of diluted earnings per share.

The loan receivable and non-current prepayments made to a third party relates to cash advanced by Oil Search to an Exploration 
and Production (E&P) company under a farm-in arrangement in respect of an exploration licence containing discovered oil resources 
and reflect the nature of the funding arrangement. The farm-in remains subject to government approvals and confidentiality. Interest 
on the loan is calculated at the lesser of 10% per annum or LIBOR plus 7.5%. The loan receivable is payable out of future production 
cash flows from the licence. The future classification of non-current prepayments to the third party is subject to either government 
approval for Oil Search to farm-in to the exploration licence or the exercise of an option permitting Oil Search to acquire an equity 
interest in the issued share capital of the E&P company.

The asset is not past due or impaired at the end of the reporting period.

Performance Rights Plan
An employee Performance Rights Plan was established in 2004, under which selected employees of the Group are granted 
rights over ordinary shares of Oil Search Limited. Vesting of the awards depends on Oil Search’s Total Shareholder Return (TSR) 
performance over a three-year period relative to peer groups of companies. The two peer groups are:

 ¸ the ASX50 (excluding property trusts and non-standard listings); and

 ¸ the constituents of the Standard and Poor’s Global Energy Index. TSR outcomes for this international group are normalised 

against a US dollar base currency to provide consistency of measurement.

For performance rights granted from 2017 onwards, the portion of awards tested against Global Energy Index increased from 50% 
to 66% while the portion of the awards tested against the ASX 50 decreased from 50% to 33%. To determine the level of vesting of 
the awards, Oil Search’s TSR over the three-year performance period is ranked against the TSR of each company in the peer groups 
over the same period.

For each peer group, if Oil Search’s TSR performance is:

 ¸ below median, that is the 50th percentile, no performance rights will vest;

 ¸ at the median, 50% of the performance rights granted will vest;

 ¸ greater than median and less than the 75th percentile, the number of performance rights that vest will increase on a straight line 

basis from 50% to 100% of the total number of performance rights comprised in that part of the award; or

 ¸ equal to or greater than the 75th percentile, the number of performance rights that vest will be 100% of the total number of 

performance rights comprised in that part of the award. 

The rights are granted for nil consideration and are granted in accordance with guidelines approved by shareholders at the Annual 
Meeting in 2004. The rights cannot be transferred and are not quoted on the Australian Securities Exchange. There are currently 56 
(2017: 49) employees participating in the Performance Rights Plans.

Restricted Share Plan
An employee Restricted Share Plan was established in 2007 where selected employees of the Group are granted restricted shares 
of Oil Search Limited. 

Restricted shares are granted under the plan in two situations. Firstly, they were granted as a way of retaining key management and 
other employees, and, secondly, by way of a mandatory deferral of a portion of a selected participant’s short-term incentive award. 
Awards under the Restricted Share Plan are structured as grants of restricted shares for nil consideration. Restricted shares are held 
on behalf of participants in trust, subject to the disposal restrictions and forfeiture conditions, until release under the terms of the 
Plan and in accordance with guidelines approved by shareholders at the Annual Meeting in 2007. There are currently 12 (2017: 10) 
employees participating in the Restricted Share Plan.

Restricted shares were priced at the closing share price at the grant date.

 OIL SEARCH ANNUAL REPORT 2018NOTES TO THE FINANCIAL STATEMENTS

FINANCIAL AND CAPITAL RISK MANAGEMENT

27 
Financial risk exposures arise in the course of the day-to-day operating activities of the Group, primarily due to the impact of oil 
price movements on revenue items and exchange rate and interest rate impacts on expenditure and statement of financial position 
items. The management of borrowings, cash and counter-parties for liquefied natural gas, oil, condensate and gas sales also create 
liquidity and credit risk exposures. Monetary assets and liabilities denominated in currencies that are different to the Group’s 
functional currency may also give rise to translation exposures.

The Group’s overall approach to financial risk management is to enter into hedges using derivative financial instruments only 
in circumstances where it is necessary to ensure adequate cash flow to meet future financial commitments. Financial risk 
management is undertaken by Group Treasury and risks are managed within the parameters of the Board approved Financial Risk 
Management Procedure. 

Foreign exchange risk

(a) 
The Group’s revenue and major capital obligations are predominantly denominated in US dollars (US$).

The Group’s residual currency risk exposure mainly originates from two different sources:

 ¸ Administrative and business development expenditures incurred at the corporate level in Australian dollars (A$); and

 ¸ Operating and capital expenditures incurred by the Group in relation to its PNG operations in Papua New Guinea kina (PGK) 

and A$.

The Group is not exposed to material translation exposures as the majority of its assets and liabilities are denominated in US$. 

Foreign exchange risk management
The Group manages its exposure to foreign exchange rate volatility by matching the currency of its cost structure to its US$ 
revenue stream. Transaction exposures are netted off across the Group to reduce volatility and avoid incurring the dealing spread 
on transactions, providing a natural hedge. The residual operating cost exposures, primarily in A$, are recurring in nature and 
therefore no long-term hedging is undertaken to minimise the profit and loss impact of these exposures. 

Cash flows related to joint ventures where Oil Search is the operator are managed independently to the Group’s corporate 
exposures, reflecting the interests of joint arrangement partners in the operator cash flows. The operator’s A$ and PGK 
requirements are bought on the spot market. Where these currencies are purchased in advance of requirements, A$ and PGK 
cash balances do not exceed three months’ requirements.

As at 31 December 2018, there were no foreign exchange hedge contracts outstanding (2017: nil).

No currency sensitivity analysis is provided as there were no derivative financial instruments in place to hedge residual foreign 
exchange exposure. 

Interest rate risk

(b) 
The Group is exposed to interest rate movements directly through borrowings and investments in each of the currencies of its 
operations. Surplus cash is invested in accordance with Board approved credit counterparty limits, based on minimum credit 
ratings, and managed to ensure adequate liquidity is maintained. Whilst some cash is held in PGK and A$, the Group’s primary 
exposure is to US interest rates.

Interest rate risk management
Interest rate risk is managed on a Group basis at the corporate level. Limits on the proportion of fixed interest rate exposure are 
applied and interest rates may be fixed for a maximum term of four years or the remaining life of term debt facilities, whichever is 
the longer.

As at 31 December 2018, there was no interest rate hedging in place (2017: nil). Cash was invested in short-term instruments with 
an average maturity of 1 to 3 months.

Interest rate sensitivity
The sensitivity analysis below has been determined based on exposure to interest rates at the reporting date and the stipulated 
change taking place at the beginning of the financial year and held constant throughout the year. 

At the reporting date, if interest rates had been 25 basis points (2017: 25 basis points) higher or lower and all other variables were 
held constant, the Group’s net profit after tax would decrease/increase by $5.0 million (2017: $4.8 million).

At the reporting date, if interest rates had been 25 basis points (2017: 25 basis points) higher or lower and all other variables were 
held constant, the Parent entity’s net profit after tax would increase/decrease by nil (2017: nil).

Commodity price risk

(c) 
The Group has exposure to commodity price risk associated with the production and sale of oil, condensate, natural gas and 
liquefied natural gas. 

Commodity risk management
The Group does not seek to limit its exposure to fluctuations in oil prices; rather the central aim of oil price risk management is to 
ensure the Group’s financial position remains sound and that the Group is able to meet its financial obligations in the event of low oil 
prices. Hedge cover targets are determined through detailed modelling of the Group’s position under various oil price scenarios. 
Any hedging programmes entered into will ensure that maturities are spread over time and there are maximum hedge cover levels 
that apply to future years. This avoids the Group being forced to price a significant proportion of its exposure in an unfavourable oil 
price environment.

Under the PNG LNG Project financing arrangements there are restrictions relating to hedging activities that may be undertaken. 
Permitted hedging instruments as defined in the financing agreements, which must be non-recourse to the participant’s Project 
interest and the Project property.

As at 31 December 2018, there was no oil price hedging in place (2017: nil). No commodity price sensitivity analysis is required as 
there was no hedging in place. 

Credit risk

(d) 
The Group has exposure to credit risk if counterparties are not able to meet their financial obligations to the Group. The exposure 
arises as a result of the following activities:

 ¸ Financial transactions involving money market, surplus cash investments and derivative instruments;

 ¸ Direct sales of liquefied natural gas, oil, condensate and gas;

 ¸ Other receivables; and

 ¸ Loan receivable.

FINANCIAL AND CAPITAL RISK MANAGEMENT (CONTINUED)

Credit risk management
Global credit limits have been established across all categories of financial transactions. These limits are based on the 
counterparties’ credit rating as issued by Standard and Poor’s and Moody’s. 

The Group markets Kutubu crude oil, blended with PNG LNG condensate, on behalf of the Joint Lifting Consortium, primarily selling 
this product to investment grade counterparties. Sales to non-investment grade counterparties are secured by letters of credit from 
investment grade banks.

An option agreement and a share pledge agreement are held as security for the third party loan receivable balance, permitting 
Oil Search Limited to acquire an equity interest in the issued share capital of the borrower (note 13). 

At 31 December 2018 there was no significant concentration of credit risk exposure to any single counterparty (2017: nil). 

The extent of the Group’s credit risk exposure is identified in the following table:

Liquidity risk

(e) 
The Group has exposure to liquidity risk if it is unable to settle financial transactions in the normal course of business and if new 
funding and refinancing cannot be obtained as required and on reasonable terms. 

Liquidity risk management
The Group manages liquidity risk by ensuring it has sufficient funds available to meet its financial obligations on a day-to-day basis 
and to meet any unexpected liquidity needs in the normal course of business. The Group’s policy is to maintain surplus immediate 
cash liquidity together with committed undrawn lines of credit for business opportunities and unanticipated cash outflows.

The Group also seeks to ensure maturities of committed debt facilities are spread over time to minimise the Group’s exposure 
to risk on the cost or availability of funds should the refinancing requirement coincide with unexpected short-term disruption or 
adverse fund-raising conditions in the capital markets. In order to avoid an exposure to any particular source of external funding the 
Group acknowledges the benefits of diversification of funding sources and where possible, aims to source its funds from a range of 
lenders, markets and funding instruments.

As at 31 December 2018, the Group has cash of $600.6 million (2017: $1,015.2 million), of which $162.0 million was invested in 
short-term instruments (2017: $620.4 million), and undrawn loan facilities of $900.0 million (2017: $850 million).

The table below shows the Group’s non-derivative financial liabilities into relevant maturity groupings based on their contractual 
maturities. The amounts disclosed in the table are the contractual undiscounted cash flows.

Financing facilities

Syndicated revolving credit facility
The Group entered into a five year non-amortising syndicated 
financing facility effective 22 June 2017 for US$600 million, 
which remains undrawn at 31 December 2018. As part of the 
terms and conditions of this new facility, Oil Search (PNG) 
Limited has provided a charge over the Debt Service Reserve 
Account and Offshore Receivable Account held in Singapore 
with Australia & New Zealand Banking Group Limited. 

Bilateral facilities
In December 2018, Oil Search entered into three new 
US$100 million bilateral revolving credit facilities, totalling 
US$300 million, with three major banks- Commonwealth 
Bank of Australia, Mizuho Bank Limited and Sumitomo Mitsui 
Banking Corporation. The new facilities each have a five-year 
term and will expire in December 2023. They replace the two 
US$125 million bilateral facilities that expired in December 
2018. As part of the terms and conditions of this new facility, 
Oil Search (PNG) Limited has provided a charge over the 
Debt Service Reserve Account and Offshore Receivable 
Account held in Singapore with Australia & New Zealand 
Banking Group Limited.

Secured loan from joint operation
Papua New Guinea Liquefied Natural Gas Global Company 
LDC, a limited duration company incorporated under the laws 
of the Commonwealth of the Bahamas (the “Borrower”) was 
organised to conduct certain activities of the PNG LNG Project 
outside of PNG, including the borrowing and on-lending to 
the Project participants of the Project Finance Debt Facility, 
and the purchase and re-sale of PNG LNG Project liquids and 
LNG. The Borrower is owned by each Project participant in a 
percentage equal to its interest in the PNG LNG Project (the Oil 
Search Limited Group interest at 31 December 2018 is 29.0% 
(December 2017: 29.0%)). Oil Search (LNG) Limited and Oil 
Search (Tumbudu) Limited are the Group’s participants in the 
PNG LNG Project (the “OSL Participants”).

Interest and principal on the Project Finance Debt Facility is 
payable on specified semi-annual dates, which commenced 
in June 2015, with the principal being repayable over 11.5 years 
based on a customised repayment profile and with 7.5 years 
remaining on the facility as at 31 December 2018. 

The liquids and LNG sales proceeds from the PNG LNG Project 
are received into a sales escrow account from which agreed 
expenditure obligations and debt servicing are firstly made 
and, subject to meeting certain debt service cover ratio tests, 
surpluses are distributed to the Project participants.

The Borrower granted to the security trustee for the Project 
Finance Debt Facility: 

 ¸ a first-ranking security interest in all of its assets, with a few 

limited exceptions;

 ¸ a fixed and floating charge over existing and future funds in 
the offshore accounts; a deed of charge (and assignment) 
over the sales contracts, LNG charter party agreements, 
rights under insurance policies, LNG supply and sales 
commitment agreements, on-loan agreements and the 
sales, shipping and finance administration agreements, 
collectively known as “Borrower Material Agreements”; and

 ¸ a mortgage of contractual rights over Borrower Material 

Agreements.

The OSL Participants have granted the security trustee for the 
Project Finance Debt Facility a security interest in all their rights, 
titles, interests in and to all of their assets, excluding any non-
PNG LNG Project assets. The Company, as the shareholder in 
the OSL Participants, has provided the security trustee for the 
Project Finance Debt Facility a share mortgage over its shares in 
the OSL Participants.

The Project Finance Debt Facility is subject to various covenants 
and a negative pledge restricting further secured borrowings, 
subject to a number of permitted lien exceptions. Neither the 
covenants nor the negative pledge have been breached at any 
time during the reporting period.

 EVENTS OCCURRING AFTER 
THE REPORTING PERIOD

Subsequent to balance date, the Directors declared an 
unfranked final dividend of US 8.5 cents per share, to be paid 
on 28 March 2019. The proposed final dividend for 2018 is 
payable to all holders of ordinary shares on the Register of 
Members on 6 March 2019. 

There were no other significant events after balance date.

Financial Completion for the PNG LNG Project was achieved 
on 5 February 2015. From that date, the completion guarantee 
that was provided by the Company for its share of the Project 
Finance Debt Facility was released. The Company has not 
provided any other security.

Capital management

(g) 
The Group manages its capital to ensure that entities in the 
consolidated Group will be able to continue as a going concern 
while maximising the return to stakeholders through the 
optimisation of the debt and equity balances. 

This involves the use of corporate forecasting models which 
facilitate analysis of the Group’s financial position, including 
cash flow forecasts to determine the future capital management 
requirements. Capital management is undertaken to ensure a 
secure, cost-effective and flexible supply of funds is available 
to meet the Group’s operating and capital expenditure 
requirements. 

Fair values

(h) 
All financial assets and financial liabilities are initially recognised 
at the fair value of consideration paid or received, net of 
transaction costs as appropriate, and subsequently carried at 
amortised cost. The fair values of financial assets and liabilities 
approximate their carrying amounts.

Independent Auditor’s Report 
to the members of Oil Search Limited 

Report on the Audit of the Financial Statements 

Opinions 

We have audited the consolidated financial statements of Oil Search Limited and its subsidiaries 
(the Group) and the financial statements of Oil Search Limited (the Company) which comprise the 
statements  of  financial  position  as  at  31  December  2018,  the  statements  of  comprehensive 
income, the statements of cash flows and the statements of changes in equity for the year then 
ended,  and  notes  to  the  financial  statements,  including  a  summary  of  significant  accounting 
policies, and the directors’ declaration.  

In our opinion 

(i) the  accompanying  financial  statements  give  a  true  and  fair  view  of  the  Group  and  the
Company’s  financial  position  as  at  31  December  2018  and  of  their  performance  for  the
year ended on that date in accordance with International Financial Reporting Standards
(including  the  interpretations  of  the  International  Financial  Reporting  Interpretations
Committee) and the Papua New Guinea Companies Act 1997; and

(ii) proper accounting records have been kept by the Group and the Company.

Basis for Opinions 

We  conducted  our  audit  in  accordance  with  International  Standards  on  Auditing.  Our 
responsibilities under those standards are further described in the Auditor’s Responsibilities for 
the Audit of the Financial Statements section of our report. We are independent of the Group and 
the  Company  in  accordance  with  the  auditor  independence  requirements  of  the  International 
Ethics Standards Board for Accountants (IESBA) Code of Ethics for Professional Accountants (the 
Code)  that are relevant to our audit of the financial statements. We have also fulfilled our other 
ethical responsibilities in accordance with the Code.  

We have no interest in the Group or the Company or any relationship other than that of the auditor 
of the Group and the Company. 

We  believe  that the  audit evidence we  have obtained  is sufficient and appropriate  to provide  a 
basis for our opinions. 

Liability limited by a scheme approved under Professional Standards Legislation.

Key audit matters are those matters that, in our professional judgement, were of most significance 
in our audit of the financial statements for the current period. 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.

Other Information 

The  directors  are  responsible  for  the  other  information.  The  other  information  comprises  the 
Directors’ Report, which we obtained prior to the date of this auditor’s report, and  the following 
additional documents which will be included in the annual report: 2018 Highlights, 2018 Review 
by  Richard  Lee,  Chairman,  Update  from  Peter  Botten  Managing  Director,  Financial  Overview, 
Production,  Gas  Development,  PNG  Exploration  and  Appraisal,  Alaska,  Promoting  a  Stable 
Operating  Environment,  Organisational  Capability,  2018  Reserves  and  Resources,  Licence 
Interests, Licence Interest Map, Board and Corporate Governance, Shareholder Information, Ten-
year Summary Table, Glossary, Corporate Directory and About Oil Search which are  expected to 
be made available to us after that date. 

Our opinion on the financial statements does not cover the other information and we do not and 
will not express any form of assurance conclusion thereon. 

In  connection  with  our  audit  of  the  financial  statements,  our  responsibility  is  to  read  the  other 
information identified above and, in doing so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise 
appears to be materially misstated.  

If, based on the work we have performed on the other information that we obtained prior to the 
date  of  this  auditor’s  report,  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.  

When  we  read  the  2018  Highlights,  2018  Review  by  Richard  Lee  Chairman,  Update  from  Peter 
Botten  Managing  Director,  Financial  Overview,  Production,  Gas  Development,  PNG  Exploration 
and Appraisal, Alaska, Promoting a Stable Operating Environment, Organisational Capability, 2018 
Reserves  and  Resources,  Licence  Interests,  Licence  Interest  Map,  Board  and  Corporate 
Governance,  Shareholder  Information,  Ten-year  Summary  Table,  Glossary,  Corporate  Directory 
and  About  Oil  Search,  if  we  conclude  that  there  is  a  material  misstatement  therein,  we  are 
required  to  communicate  the  matter  to  the  directors  and  use  our  professional  judgement  to 
determine the appropriate action.  

Responsibilities of the Directors for the Financial Statements 

The directors of the Company are responsible for the preparation of the financial statements that 
give a true and fair view in accordance with International Financial Reporting Standards (including 
the  interpretations  of  the  International  Financial  Reporting  Interpretations  Committee)  and  the 
Papua New Guinea Companies Act 1997 and for such internal control as the directors determine 

160

 OIL SEARCH ANNUAL REPORT 2018INDEPENDENT AUDITOR’S REPORT
f o r  the  yea r  en ded 31 D ecemb er 2018

is  necessary  to  enable  the  preparation  of  the  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 ability of the 
Group and the Company to continue as going concerns, 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  the  Company  or  to  cease  operations,  or  have  no  realistic 
alternative but to do so.  

Auditor’s 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  the  International  Standards  on 
Auditing will always detect a material misstatement when it exists. Misstatements can arise from 
fraud  or  error  and  are  considered  material  if,  individually  or  in  the  aggregate,  they  could 
reasonably be expected to influence the economic decisions of users taken on the basis of these 
financial statements. 

As  part  of  an  audit  in  accordance  with  the  International  Standards  on  Auditing,  we  exercise 
professional judgement and maintain professional scepticism throughout the audit. We also:   

 

Identify and assess the risks of material misstatement of the financial statements, whether 
due to fraud or error, design and perform audit procedures responsive to those risks, and 
obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. 
The risk of not detecting a material misstatement resulting from fraud is higher than for 
one resulting from error,  as fraud  may  involve  collusion, forgery,  intentional  omissions, 
misrepresentations, or the override of internal control.  

  Obtain an understanding of internal control relevant to the audit in order to design audit 
procedures  that  are  appropriate  in  the  circumstances,  but  not  for  the  purpose  of 
expressing  an  opinion  on  the  effectiveness  of  the  Group’s  or  the  Company’s  internal 
control.  

  Evaluate  the  appropriateness  of  accounting  policies  used  and  the  reasonableness  of 

accounting estimates and related disclosures made by the directors.  

  Conclude  on  the  appropriateness  of  the  directors’  use  of  the  going  concern  basis  of 
accounting  and,  based  on  the  audit  evidence  obtained,  whether  a  material  uncertainty 
exists related to events or conditions that may cast significant doubt on the Group’s and 
the  Company’s  ability  to  continue  as  going  concerns.  If  we  conclude  that  a  material 
uncertainty exists, we are required to draw attention in our auditor’s report to the related 
disclosures  in  the financial statements or, if such  disclosures are inadequate, to modify 
our opinion. Our conclusions are based on the audit evidence obtained up to the date of 
our  auditor’s  report.  However,  future  events  or  conditions  may  cause  the  Group  or  the 
Company to cease to continue as a going concern.  

  Evaluate  the  overall  presentation,  structure  and  content  of  the  financial  statements, 
including the disclosures, and whether the financial statements represent the underlying 
transactions and events in a manner that achieves fair presentation.

INDEPENDENT AUDITOR’S REPORT
f o r  the  yea r en ded 31 D ecemb er 2018

We  communicate  with  the  directors  regarding,  among  other  matters,  the  planned  scope  and 
timing of the audit and significant audit findings, including any significant deficiencies in internal 
control that we identify during our audit.  

We  also  provide  the  directors  with  a  statement  that  we  have  complied  with  relevant  ethical 
requirements regarding independence, and to communicate with them all relationships and other 
matters  that  may  reasonably  be  thought  to  bear  on  our  independence,  and  where  applicable, 
related safeguards.  

From  the  matters  communicated  with  the  directors,  we  determine  those  matters  that  were  of 
most significance in the audit of the financial statements of the current period and are therefore 
the key audit matters. We describe these matters in our auditor’s report unless law or regulation 
precludes  public  disclosure  about  the  matter  or  when,  in  extremely  rare  circumstances,  we 
determine  that  a  matter  should  not  be  communicated  in  our  report  because  the  adverse 
consequences of doing so would reasonably be expected to outweigh the public interest benefits 
of such communication. 

Report on the Remuneration Report 

Opinion on the Remuneration Report 

We have audited the Remuneration Report included in pages 92 to 117 of the directors’ report

2018, has been prepared in accordance with section 300A of the Corporations Act 2001.  

Responsibilities  

The  directors  of  the  Company  have  voluntarily  presented  the  Remuneration  Report  which  has 
been prepared in accordance with the requirements of section 300A of the Corporations Act 2001.

conducted in accordance with International Standards on Auditing.

Definition of reserves and contingent resources 
Estimates of reserves and contingent resources are conducted 
to Society of Petroleum Engineers (SPE) standards on a Proved 
(1P and 1C) and Proved and Probable (2P and 2C) basis.

Proved reserves
Proved reserves are the estimated quantities of crude oil, natural 
gas and natural gas liquids which geological and engineering 
data demonstrate with reasonable certainty to be recoverable 
in future years from known reservoirs under existing economic 
and operating conditions. Proved reserves are limited to those 
quantities of oil and gas which can be expected, with little 
doubt, to be recoverable commercially at current prices and 
costs, under existing regulatory practices and with existing 
conventional equipment and operating methods. Proved (1P) 
reserves are probabilistically calculated reserves having a 90 
per cent confidence level (P90); such reserves have a 90 per 
cent likelihood of being equalled or exceeded.

Probable reserves
Probable reserves are those reserves which geological and 
engineering data demonstrate to be potentially recoverable, 
but where some element of risk or insufficient data prevent 
classification as proven. Probable reserves are calculated 
by subtracting proven reserves from those probabilistically 
calculated reserves having a 50 per cent confidence level (P50). 
Therefore, “Proved plus Probable” (2P) reserves are defined 
as those reserves which have a 50 per cent likelihood of being 
equalled or exceeded.

Contingent resources
The Company’s technically recoverable resources for its 
discovered but uncommercialised gas fields are classified 
as contingent resources. 2C denotes the best estimate of 
contingent resources

ABOUT OIL SEARCH

Oil Search was established in Papua New Guinea (PNG) in 1929, where it operates 

all of the country’s producing oil fields, has a 29% interest in the PNG LNG 

Project, operated by ExxonMobil PNG Limited, and holds an extensive appraisal 

and exploration portfolio. The Company also has interests in a number of major 

undeveloped gas fields, including Elk-Antelope in PRL 15, operated by Total SA,  

and P’nyang in PRL 3, operated by ExxonMobil.  These fields are expected to underpin 

a proposed three-train, 8 MTPA LNG development, to be constructed on the existing 

PNG LNG plant site, doubling the LNG capacity in PNG.

The Company is undertaking a range of exploration and appraisal activities in  

the North-West Highlands, the Forelands, the onshore and shallow water offshore 

Gulf and Deepwater regions of PNG, to support further LNG expansion in the country 

and ensure the availability of gas to backfill existing and future LNG capacity. 

In February 2018, Oil Search farmed into a world class portfolio of oil assets on  

the Alaska North Slope, USA.  These assets offer significant upside and complement 

the Company’s high-returning PNG gas portfolio.  Oil Search assumed operatorship of 

the assets in March 2018, positioning the Company at the forefront of the development 

of the prolific Nanushuk play in the Pikka Unit, one of the largest conventional oil 

discoveries in the US in more than 30 years.  

Oil Search is listed on the Australian and Port Moresby security exchanges  

(Share code: OSH) and its ADRs trade on the US Over the Counter market  

(Share code: OISHY).
