Letter to Shareholders

In 2017, Schlumberger celebrated the 90th anniversary 

of the first well logging survey, which took place in the 

Pechelbronn  oil  field  in  France  in  September  1927.  

This log established the science of subsurface metrology 

and provided the impetus for the business venture that 

eventually became Schlumberger.

Paal Kibsgaard 
Chairman and Chief Executive Officer

Schlumberger full-year 2017 revenue of $30.4 billion increased 9% year on year. This reflects a full year of activity from the acquired 
Cameron businesses compared with only three quarters of activity in 2016. In addition to the impact of Cameron, revenue growth 
was driven by unconventional land resource developments in North America due to the recovery in activity combined with market 
share gains and improved pricing as the oil and gas industry began to emerge from the longest and deepest downturn in 30 years.

Following two successive years of E&P investment cuts, operators increased their upstream spend in North America by more than 
30% in 2017. The increase in oil price afforded by the OPEC agreement gave US producers a means to increase their investment in 
tight oil. However, apprehension related to growing US supply, and uncertainty surrounding the duration of OPEC- and Russia-led 
production cuts held international spending to a level 3% below 2016.

During 2017, the outlook improved for international markets, evidenced by a significant increase in the sanctioning of new 
projects. The number of final investment decisions tripled in 2017 compared with 2016, with 75% of the new projects planned for 
shallow and deepwater offshore environments.

After starting the year at $55 per barrel, Brent prices fell to $44 in June and then recovered to $67 by the end of the year.  
The price increase resulted from 2017 demand growth of 1.5 million barrels per day and strong adherence to a production 
agreement between OPEC and Russia, which served to reduce oil production by an average of 1.6 million barrels per day compared 
with the fourth quarter of 2016. Strong demand and restricted supply accelerated the depletion of stocks as the year progressed.  
By September, OECD crude and product stocks had returned to 2015 levels.

As the oil market began to rebalance in 2017, replacement of conventional oil reserves remained a challenge. In 2017, discoveries 
were at an all-time low due to lower exploration activity, and more than 60% of discovered resources were gas. Oil discoveries 
accounted for only 3.4 billion barrels—while about 30 billion barrels of conventional oil is produced each year—representing  
a reserves replacement ratio of only 11%.

In the natural gas markets, low Henry Hub prices and flat domestic consumption allowed the US to transition from importer to 
exporter of natural gas for the first time since 1957, and Liquefied Natural Gas was the enabler. Global LNG trading increased 
11% year on year driven by demand in Asia. LNG supply growth was also strong, with the addition of six new liquefaction trains 
in 2017. In today’s well-supplied market, both producers and consumers are reluctant to invest in new projects. While the short-
term market outlook remains challenged, strong longer-term demand growth signals a future need for new LNG supply capacity.

Schlumberger financial performance in 2017 was driven by land 
activity in North America, where revenue increased over 80% in 
line with the average rig count increase. Continued expansion 
of  the  Schlumberger  hydraulic  fracturing  presence  in  North 
America  resulted  in  additional  fleet  redeployments,  which 
benefited the Production Group. Drilling Group revenue in North 
America land increased due to the continuing high demand for 
longer horizontal lateral sections in shale oil wells. Increased 
Cameron Surface and Drilling Systems product sales and services 
also contributed to the strong financial performance in North 
America.  North  America  revenue,  including  offshore,  grew  
42% year on year.

International  revenue  decreased  2%  compared  with  2016. 
This  decline  was  driven  by  soft  demand  for  exploration-  and 
development-related  products  and  services  as  E&P  budgets 
remained tight. Activity in Latin America decreased due to  the 
Schlumberger decision to align operations with cash collections 
in  Venezuela.  Robust  activity  in  the  Middle  East  and  Russia, 
driven  by  integrated  drilling  and  production  projects,  as  well 
as an additional quarter of activity from the acquired Cameron 
businesses partially offset these decreases.

During the past three years of unprecedented market downturn, 
Schlumberger has proactively sought to strengthen its technology 
offering and presence in key markets around the world. The most 
recent example is the expansion of its hydraulic fracturing presence 
in North America land through the purchase of the US fracturing 
and pumpdown perforating businesses from Weatherford. In line 
with the challenging business environment, over the same period 
Schlumberger has restructured all relevant parts of the company 
in terms of both size and organizational structure to maximize its 
market competitiveness and operational agility.

With  the  significant  changes  seen  in  customer  priorities  and 
buying habits in recent years, Schlumberger has continued to 
evaluate the present and future return prospects for all of its 
product  lines  as  it  seeks  to  maximize  its  long-term  financial 
performance.  Based  on  this  in-depth  analysis,  Schlumberger 
identified the seismic acquisition business as the only product 
line that does not meet Schlumberger return expectations going 
forward,  even  after  factoring  in  an  eventual  market  recovery. 
Schlumberger has, therefore, taken the difficult decision to exit 
the  marine  and  land  seismic  acquisition  market  and  instead 
operate the WesternGeco product line as an asset-light business, 
built on its leading position within multiclient, data processing, 
and geophysical interpretation.

Looking at the oil market, the strong growth in demand is projected 
to continue in 2018 on the back of a robust global economy. On the 
supply side, the extension of the OPEC- and Russia-led production

cuts is already translating into higher-than-expected inventory draws. 
In North America, 2018 shale oil production is set for another year 
of  strong  growth  as  the  positive  oil  market  sentiments  will  likely 
increase both investment appetite and availability of financing. At the 
same time, the production base in the rest of the world is showing 
fatigue  after  three  years  of  unprecedented  underinvestment.  The 
underlying signs of weakness will likely become more evident in the 
coming year as the production additions from investments made in 
the previous upcycle start to noticeably fall off. Taken together, this 
means the oil market is now in balance and the previous over-supply 
discount is gradually being replaced by a market tightness premium, 
which makes Schlumberger increasingly positive on the global outlook  
for its business.

Schlumberger financial 
“
performance in 2017 was driven 
by land activity in North America, 
where revenue increased over 
80% in line with the average 
rig count increase.”

This year, new technology sales from all Groups contributed to 24% of total sales, which is a 4% increase over the previous year.  
The Schlumberger commitment to developing innovative technology included commercialization of key technologies such as the DELFI 
cognitive E&P environment, which enables collaboration across E&P teams and leverages the full potential of all available data and 
science to optimize assets; DrillPlan digital well construction planning solution, the first application in the DELFI environment; and 
Lift IQ* production life cycle management service that provides monitoring, diagnostics, and optimization of artificial lift systems in 
real time. 

One measure of our health and safety performance held steady as our combined lost time injury frequency was the same as 2016. 
Although Schlumberger maintains a constant focus on safety, our auto accident injury rate deteriorated slightly compared with 2016. 
Regretfully, we suffered one driving-related fatality in North America involving a contractor. We will continue to guard against the risks 
that road journeys present by seeking continuous improvement of the measures we have in place to keep our people safe through our 
global network of Journey Management Centers.

Over the last few years, our transformation efforts have resulted in the design of a new way of working through which our operational 
processes have been reengineered and our product lines and GeoMarket* organizations restructured. In 2017, we completed the first 
deployment phase of our SAP-based IT system in North America and continued to see service delivery efficiency gains due to improved 
resource planning and delivery and reliability-centered asset engineering, manufacturing, and maintenance. This new way of working 
at Schlumberger is a comprehensive program of change that is being systematically deployed around the globe.

This year also marked the third release of the Schlumberger Global Stewardship Report, the results of which are filed with seven major 
environmental, social, and governance (ESG) rating agencies. The report details our ESG program, the seeds of which began with 
initiatives launched nearly 20 years ago.

We believe that the oil market is now in balance as the previous oversupply discount is gradually being replaced by a market tightness 
premium. We expect to see increases in E&P investment in the main producing regions around the world to replace production that 
has been lost because of natural decline.

On behalf of Schlumberger people around the world, I want to thank our stakeholders for their confidence and support. I also want  
to personally thank our employees for their dedication and commitment.

Performed by Schlumberger

Schlumberger  people  have  a  steadfast  commitment  
to  customers,  innovative  technology,  safety,  and  quality.  
We  are  people  who  thrive  on  the  challenge  to  excel  in 
our  quest  to  exceed  expectations.  In  2001,  the  company 
established  the  Performed  by  Schlumberger  program  to 
recognize  projects  and  their  team  members  who  have  
demonstrated  exceptional  levels  of  teamwork,  innovation, 
and business impact for Schlumberger and its customers. 

In 2017, 444 projects competed for the Chairman’s Award. 
As the program’s highest honor, the award recognizes one 
project as an outstanding example of the company’s core 
values: our people, our commitment to technology, and our 
determination to produce superior profits. 

The team for the Achieving Excellence: The Longest Well Ever 
project won this year’s Chairman’s Award for its work with 
the Sakhalin-1 Consortium to drill a 49,212-ft extended-reach 
well on the Orlan Platform offshore Sakhalin, Russia. 

The Achieving Excellence: The Longest Well Ever team received the 
Performed by Schlumberger Award from Chairman and CEO Paal Kibsgaard 
(far left) and Senior VP of Marketing & Technology Justin Rounce (third 
from left). Also pictured, from the left, Jon Acquaviva, Dmitriy Kofman, 
Sheldon Rawlins, Jimmy Varughese, Danil Zazulya, Catherine MacGregor, 
and Richard Brown.

This set a new benchmark for extended-reach drilling that exceeds 
the previous record by 4,921 ft. Historically, new drilling records 
have been characterized by incremental gains in measured depth, 
and this new benchmark was achieved in a technically challenging 
subarctic, frontier environment.

The Sakhalin Extended-Reach Drilling Center of Excellence integrated 
the  domain  expertise  and  technology  from  10  Schlumberger  
product  lines  and  worked  closely  with  the  Sakhalin-1  Consortium  
during the two years it took to plan and drill this well in the Chayvo 
field—with drilling completed in 103 days. This successful collaboration 
achieved a 37% increase in the rate of penetration compared with  
the previous extended-reach drilling record from 2015.

Digital Technology 
Integration

Digital enablement is revolutionizing many industries, 
yet its adoption by the E&P industry has been 
limited to date. Today, digital enablement permeates 
everything Schlumberger does—from research 
and engineering, manufacturing, operations, and 
maintenance to resource planning. 

Building on our domain expertise and our leadership 
in hardware and software, Schlumberger is also 
developing new software and a digital foundation 
that removes barriers between disciplines to create 
seamless digital workflows for all E&P domains.  
This new software moves beyond incremental 
change—it represents a new way of working that 
provides new opportunities, unmatched performance, 
and a step change in efficiency.

Schlumberger is already capitalizing internally  
on the value unlocked by digital enablement. In 
addition, value from new digital workflows will be 
increasingly shared between Schlumberger and its 
customers as we commercialize new technologies  
and further enable existing products and services.

Advanced computational capabilities in the DELFI cognitive E&P environment  
are used to predict well production profiles in the Petrel* E&P software platform.

Establish a New Way of Working 

In  a  medium-for-longer  oil  price  environment,  increased  
demand for oil requires investment in technology and business 
models that will improve efficiency and enable unprecedented 
levels  of  integration  and  collaboration.  The  development   
of digital technology is disrupting the traditional way of working 
in  the  oil  and  gas  industry  and  creating  a  step  change  in  
operational and business performance for both Schlumberger 
and its customers. 

Although  digital  technology  has  been  integrated  into  nearly 
every  facet  of  our  personal  lives,  its  adoption  in  the  E&P 
industry  has  been  limited.  The  industry’s  traditional  way  of 
working presents barriers to the sharing of data and technical 
knowledge  among  the  domain  experts  who  make  important 
decisions directing the discovery and development of oil and gas 
resources. Integrating digital technology into E&P workflows 
requires extensive domain expertise about the entire system—
from  hardware  and  software  technologies  to  the  complexity 
of  the  data  and  numerous  systems  involved.  To  tackle  this  
challenge, Schlumberger has the domain expertise and global 
experience in every step of the E&P process, a knowledge that 
stems from our focus on the science of subsurface measurement 
since the company’s foundation.

In addition, the current medium-for-longer oil price environment 
demands a new approach for the E&P industry. This new approach 
requires  a  system-level  view  to  fully  optimize  the  finding,  
development, and production of new oil and gas resources as well 
as the operation of existing oil and gas fields. Innovation around  
a single element of the E&P development chain cannot maximize 
efficiency  if  done  in  isolation.  The  new  approach  requires   
a complete understanding of what each element contributes to 
the entire chain. Schlumberger believes that achieving this will 
require a profound change in the way the industry operates and 
interacts—changing the way we work and yet also changing the 
very nature of that work.

Achieving  change  entails  a  new  collaborative  mindset,  end-
to-end  systems  knowledge,  and  redesigned  business  models 
that firmly establish and support new ways of working based  
on innovative technology and domain expertise. 

“

Over the last three years, Schlumberger has 
created technology centers that innovate 
within the rapidly evolving world of digital 
technology and automation.”

Over  the  last  three  years,  Schlumberger  has  created 
technology  centers  that  innovate  within  the   rapidly 
evolving  world  of  digital  technology  and  automation.   
In  line  with  our  long  history  of  working  with  research  and  
engineering  partners,  these  centers  have  formed  strong 
relationships  with  an  extensive  network  of  leading  digital  
technology  companies,  creating  building  blocks  of  expertise 
in  areas  such  as  cloud  technology,  data  analytics,  machine 
learning,  artificial  intelligence,  robotics,  and  automation.  

Through this ecosystem of extended knowledge, Schlumberger 
now has deeper access to the best and most advanced digital 
technologies  and  capabilities  available  today.  Together  with  
our partners, we are developing the solutions we believe will 
meet the industry’s needs.

System-Level Optimization 

Although  data  is  at  the  center  of  E&P  development,  some 
exploration  wells  fall  short  of  their  objectives  as  a  result  
of unexpected geology or unanticipated hazards. Increasing the 
volume and quality of accessible data equips the E&P industry 
to make better-informed decisions that reduce subsurface risk, 
optimize production, and maximize recovery—but only if that 
data is efficiently managed.

Petrotechnical  experts  working  on  exploration  projects  
spend  more  than  half  of  their  time  finding  and  preparing  
the  data  they  need  to  make  their  decisions.  The  subsequent 
data  interpretation  is  also  very  time  consuming,  and  these 
interpretations  drive  important  decisions  for  the  reservoir’s 
development plan.

Changing  the  way  the  industry  works  begins  with  a  critical 
assessment  of  how  the  data  is   used  across  reservoir  
characterization,  well  construction,  and  field  production. 
During  the  development  process  as  it  is  practiced  today,  
different types of data exist in silos, making holistic analysis 
impossible. Without a system approach, precious information 
and time are lost because the lack of interface among different 
systems makes it difficult to share localized knowledge.

The  DELFI  cognitive  E&P  environment  was  developed  to 
enable  a  new  way  of  working.  As  the  first  of  its  kind  in  the  
oil  and  gas  industry,  this  secure,  cloud-based  environment 
harnesses  data,  scientific  knowledge,  and  domain  expertise 
to  fundamentally  change  the  industry’s  way  of  working.  The 
new  DELFI  environment  makes  applications  and  workflows 
accessible  to  every  user.  Gone  are  the  impenetrable  silos,  
because in the DELFI environment, every stakeholder can build 
common workspaces for data, models, and interpretations while 
respecting proprietary information boundaries.

A geophysicist working in the DELFI environment selects data from different sources in the E&P Data Lake by searching its global multiclient library. By visualizing 
integrated data models, the geophysicist can enhance his understanding of the subsurface in a specific area of interest.

The  DELFI  environment  provides  the  best  possible 
representation of the surface and subsurface, including existing 
wells and facilities, plus those that are planned. The outcome 
is shared insight among all users and among all stakeholders 
to  eliminate  the  silos  of  today.  Performance  is  boosted  as  
time  cycles  are  compressed  across  the  business,  uncertainty 
in  planning  is  reduced  through  greater  understanding,  and 
new  opportunities  are  created  to  extend  domain  science  
into  drilling  and  production  operations.  Everything  working 
together enhances business value for both Schlumberger and 
its customers.

When  Schlumberger  launched  the  DELFI  environment,  the 
company  deployed  an  E&P  Data  Lake  on  the  Google  Cloud 
Platform, which includes more than 1,000 3D seismic surveys,  
5 million wells, 1 million well logs, and 400 million production 
records from around the world. This Data Lake makes data from 
different sources available through a common interface, making 
it easier for users to discover what the data is, have access to it, 
and use it to maximum advantage. As they work with this vast 
amount of information in the cloud, the result is a step change 
in scalability and performance.

The  DELFI  environment  leverages  data  analytics,  machine 
learning, high performance computing (HPC), and the Internet 
of  things  (IoT),  all  of  which  work  together  to  maximize  
operational  efficiency  and  deliver  optimized  production   

at the lowest cost per barrel. This environment facilitates a new 
level  of  integration  among  the  geophysics,  geology,  reservoir 
engineering, drilling, and production domains. There are many 
workflows throughout exploration and production, and a digital 
approach accelerates access to all the available data. For that 
reason, the DELFI environment is also an open and extensible 
system in which Schlumberger customers and software partners 
can add their own intellectual property and workflows.

Schlumberger is an early adopter of HPC, and the teams at its 
technology centers—Menlo Park, California; Houston, Texas; 
Gatwick,  UK;  and  Mumbai,  India—have  been  leading  the  
application of HPC for seismic processing. Today, Schlumberger 
has  a  state-of-the-art  HPC  infrastructure  on  the  cloud  that 
runs thousands of central processing unit (CPU) and graphics 
processing  unit  (GPU)  nodes,  and  it  is  the  largest  cloud  
computer cluster of its kind in the oil and gas industry. Cloud-
based HPC creates new opportunities for advanced visualization 
and  machine  learning  to  enhance  the  value  of  oil  and  gas   
data assets. 

But how exactly does the DELFI environment change not just 
the way of working but also the nature of work? The answer is by 
enabling working in a common environment as well as creating 
accessibility  and  augmented  intelligence  for  information  
sharing. Data is delivered to the right people at the right time so 
all recipients can maximize use of the latest information based

on their role and expertise. Barriers to effective communication 
are  eliminated,  improving  efficiency  during  the  process  so 
domain experts can spend more time on high-level solutions to 
the unique challenges every reservoir presents. Decisions that 
used to take days can now be completed in minutes.

The advancement of digital technology enablement within the 
oil and gas industry sets new demands in terms of cybersecurity. 
Schlumberger has been providing secure commercial software, 
information  management,  and  IT  infrastructure  across  the 
entire  E&P  life  cycle  for  35  years.  In  2015,  Schlumberger  
obtained Service Organization Controls 2 (SOC 2®) Type 1 and 2 
accreditations for cybersecurity through an external audit. The 
SOC 2 accreditation provides detailed information about the 
controls Schlumberger has implemented in regard to security, 
availability, and integrity of the systems the company uses to 
process customer data as well as the confidentiality and privacy 
of the information that these systems process.

By working in the DELFI environment, oil and gas experts will 
be able to connect in a different way to complete shared work

goals and expand their sphere of contact to other intellectually 
challenging  domains.  They  will  have  access  to  tools  and  
technologies  that  relieve  them  of  routine,  repetitive  tasks, 
effectively freeing up their valuable time to focus on innovative 
solutions.

This  new  way  of  working  is  possible  only  by  combining   
the  latest  offerings  in  digital  technology  with  the  domain  
know-how  and  hardware  and  software  technology  leadership 
that  can  optimize  workflows,  increase  the  efficiency   
of operations, and ultimately decrease the cost per barrel.

Schlumberger Software  
Technology Innovation Center

Schlumberger  Software  Technology  Innovation  Center  (STIC) 
was  established  in  2014  with  a  goal  of  leading  the  oilfield 
digital transformation by taking advantage of technology trends 
driven by Silicon Valley companies. The center team consists  
of a highly technical workforce, including Schlumberger experts  
and recent university graduates. The technical staff includes 
cloud and big data engineers, user experience (UX) designers, 
front-end  web  developers,  data  scientists,  and  machine   
learning experts.

The  primary  focus  of  STIC  is  to  deliver  technology  proof 
points—working code that leverages new technology applied 
to oilfield challenges. The center regularly aligns its priorities 
with stakeholders from the Schlumberger product lines. STIC  
is  closely  connected  with  the  Schlumberger  software  
community,  hosting  hackathons  and  design  sprints  to  bring 
engineers, stakeholders, and end users together to accelerate 
the software-development process.

The center maintains affiliations with earth science, computer 
science,  and  computational  mathematics  departments  of  
Bay Area universities, most notably Stanford. It also partners 
with  companies  in  Silicon  Valley  to  gain  knowledge  about 
how digital technology and infrastructure are applied in other 
industries. STIC has become a focal point for Schlumberger to 
communicate its digital vision with customers, with the center 
frequently  hosting  meetings  and  workshops  that  provide  in-
depth technical engagement.

Innovation Center in Menlo Park, California.

Over the past three years, STIC has worked with and evaluated 
more  than  400  companies  and  pursued  projects  with  over  
70 of them. By working together with partners, we continuously 
learn about new capabilities and opportunities while integrating 
with the Silicon Valley ecosystem. Through close collaboration 
with these digital technology partners, Schlumberger is able to 
develop digital technology solutions in less time, thus reducing 
the development lead time. This is our new way of working for 
technology development.

Reduce Uncertainty,  
Accelerate Decision Making

The first step in the E&P development process is to create a 
digital representation of what is hidden below the Earth’s surface.  
To  accomplish  that,  measurements  and  data  from  multiple 
sources  are  combined  to  create  a  model  of  the  subsurface. 
Experts from multiple technical domains—geology, geophysics, 
and petrophysics as well as reservoir, drilling, and production 
engineering—use their knowledge to further refine the model. 
This initial combination of measurements and data, along with 
expert  interpretation,  are  fundamental  to  some  of  the  most 
critical decisions about the reservoir—decisions that will affect 
its entire life cycle.

The Petrel E&P software platform, which has become an industry 
standard and was introduced in 2003, is also now available in the 
DELFI environment. The Petrel platform uses a shared-earth 
approach that enables standardized workflows from exploration 
to production. Every decision is an informed one that is made 
with a clear understanding of both opportunities and risks. 

Repeatable and automated workflows enable users to capture 
best  practices  and  share  them  throughout  the  organization. 
Petrotechnical experts and asset teams can analyze, interpret, 
and model the subsurface in real time in a highly collaborative 
manner. All of this works together to decrease uncertainty and 
accelerate the decision-making process, thereby accelerating 
the time to first oil.

Numerous  applications  are  also  available  in  the  DELFI  
environment  for  access  as  required.  The  Techlog*  wellbore 
software platform for the analysis and validation of wellbore 
data,  the  ECLIPSE*  industry-reference  reservoir  simulator, 
and  INTERSECT*  high-resolution  reservoir  simulator  for  
accurate, efficient simulation of reservoir behavior over time 
are just a few examples. Having global access to applications, 
instead  of  the  conventional  siloed  approach,  further  helps  
to optimize field development plans and facilities design. 

Working  in  the  cloud  within  the  DELFI  environment  also  
enables users to take advantage of high performance computing 
to process large volumes of data during the construction and 
maintenance  of  evergreen  reservoir  models.  This  includes 
higher-resolution  seismic  data,  wireline  logging  of  wells,  
and  the  testing  and  characterization  of  reservoir  fluids.  Key 
benefits to working in the cloud environment are fast access to 
data visualization, interpretation, and application to refine the 
model during different phases of the E&P life cycle.

Geoscientists review petrophysical measurements and 3D seismic data in the 
Petrel E&P platform to improve modeling of a complex formation.

Increase Efficiency, Minimize Risks 

The software and systems used to drill and complete a well are 
some  of  the  most  complex  technologies  in  the  world,  crucial 
to making both the few major development decisions and the 
millions of small but critical ones that are made daily. Every well 
drilled comes with a unique set of conditions that also vary during 
the construction process. The DrillPlan digital well construction 
planning  solution  is  the  first  cloud-native  application  to  be 
launched in the DELFI cognitive E&P environment, providing 
a radically new way of working to deliver higher-quality drilling 
programs  faster.  This  is  achieved  through  the  automation  of 
repetitive tasks and validation of end-to-end workflows to ensure 
that the entire plan is coherent.

The DrillPlan solution employs an iterative workflow. As new data 
is added, the plans improve and future programs can learn from 
prior experience. This iterative process also improves planning 
efficiency because any changes to the plan, such as recalculating 

11

14781schD2R3.nar.indd   11

2/13/18   11:19 PM

the path that the well should follow, can be completed in minutes 
rather than days. The DrillPlan solution in the DELFI environment 
enables  seamless  collaboration  between  experts,  from  the 
geologist to the drilling engineer and production engineer.

The resulting digital drilling plan integrates activities, processes, 
and people, placing the right information in the right hands at 
the right time. The DrillPlan solution also monitors deviations 
from the original plan for continuous improvement via machine 
learning.  When  domain  experts  make  dynamic  changes  to 
the  plan,  the  software  immediately  updates  the  shared-earth 
model, which also augments learning for the next well plan. By 
automating repetitive tasks, domain experts have more time to 
use their advanced skills to create new insights. The result is a 
drilling program that maximizes accuracy, efficiency, and value 
at the same time as minimizing risks. 

The DrillPlan solution leverages the digital technologies of the 
Microsoft  Azure  and  the  Azure  Stack  hybrid  cloud  solution. 
Interoperability  with  Microsoft  Office  365  and  Microsoft  

Teams empowers new levels of collaboration among teams and 
stakeholders, significantly improving productivity.

After more than a year of testing by oil and gas companies in the 
United States and Canada, the DrillPlan solution has proved to be 
comprehensive and powerful, delivering well planning programs in 
days rather than weeks. The DrillPlan solution has been available 
in  North  America  land  operations  since  the  fourth  quarter  
of 2017, and Schlumberger continues to develop its functionalities 
to meet the needs of the global exploration and development market  
in 2018 and beyond.

In a future that requires increasing production to meet global 
demand for oil and gas resources, the Schlumberger goal is to 
reduce the planning process from weeks to days. The digital way of 
working, such as the DrillPlan solution in the DELFI environment, 
facilitates  that  goal  by  enabling  iterative  collaboration  among 
team members working on the latest model. This is one example 
of  how  Schlumberger  is  using  digital  technology  to  improve 
collaboration within the industry.

Schlumberger Limited  
Industrial Internet Center 

Located  in  Sugar  Land,  Texas,  the  Schlumberger  Limited 
Industrial  Internet  Center  focuses  on  architecture  and  
infrastructure  development  for  the  cloud,  data,  industrial 
Internet  of  things  (IoT),  automation,  and  cybersecurity  
across  multiple  platforms.  Established  in  2016,  the  center 
comprises experienced IoT professionals with knowledge of 
other industries, recent graduates, and personnel from other 
Schlumberger hardware and software technology centers.

Today, consumer technologies that tap into the IoT include 
products such as wearable health monitors and smart home 
appliances.  This  gives  us  the  ability  to  connect  different  
types of devices, gather relevant data, and apply analytical 
techniques to gain valuable insights.

Adopting  the  IoT  in  the  E&P  industry,  however,  presents 
several  unique  challenges.  First,  there  is  the  nature  of  oil 
and gas equipment as well as the broad global footprint of 
where these operations occur. Then there is the need for data 
integrity and the highest level of cybersecurity. 

Internet  of  Things  Production  Systems  Engineer  Miguel  Lopez  and 
Automation Engineer Mona El Hares inspect a scanner device used in 
an application at the Schlumberger Limited Industrial Internet Center

Based  on  a  thorough  understanding  of  equipment  design, 
performance  factors,  and  domain  use,  the  center’s  team 
of  experts  collaborates  with  other  Schlumberger  software 

teams around the globe to establish the infrastructure for a 
scalable, accessible, and flexible data store—where all the  
data is shared in a common ecosystem—to enable improved 
business intelligence.

Decrease Cost per Barrel 

Schlumberger is committed to technology and processes that 
enhance efficiency and decrease the cost per barrel. An ongoing 
consideration is that about 85% of the total cost of ownership 
(TCO) of tools and equipment accumulates from the moment 
they  are  deployed  until  the  day  they  are  retired.  Therefore, 
improving the management of assets throughout their life cycle 
is a primary concern for Schlumberger and its customers.

The  extent  of  the  Schlumberger  global  footprint  provides 
the scale to take on any size project and the reach to quickly 
respond  to  customer  needs  in  any  corner  of  the  world.   
To properly maintain the global fleet of assets that is the basis 
of  these  capabilities,  Schlumberger  relies  on  its  Technology 
Lifecycle Management (TLM) organization. The organization 
acts as a bridge between Engineering and Manufacturing and 
field operations. The TLM organization uses industry-leading 
maintenance processes and ensures that sustaining activities 
are  aligned  with  the  specific  demands  that  vary  among  
GeoMarket regions.

A maintenance supervisor at the Denton Center of Reliability and Efficiency 
in Texas oversees remote hydraulic fracturing operations.

The goal of the TLM organization is to reduce the TCO of every 
asset while providing the most reliable tools and equipment to 
field operations in a timely manner. Monitoring and surveillance 
use software engines and data science to improve operations 
reliability and efficiency, which together improve our customers’ 
performance.

One  example  of  how  Schlumberger  is  using  TLM  to  improve 
asset  utilization  and  reduce  TCO  is  in  the  deployment  of  
OneStimSM products  and  services  on  land  in  North  America 
for  unconventional  reservoir  completions.  Fracturing  fleets 
are  akin  to  a  high-volume  factory  where  each  fleet  consists 
of  more  than  40  pieces  of  equipment  and  4,000  replaceable 
components  to  be  maintained  on  location  by  a  team  of  11  
crew  members.  Each  well  requires  four  to  seven  million  
pounds  of  sand,  which  is  transported  as  140  truckloads  
or  in  35  railroad  cars.  The  equipment  and  personnel   
at  a  fracturing  operation  are  part  of  a  changing  worksite   
environment that needs to move and scale in size for a new location  
every few weeks.

This type of predictive health monitoring applied to automatic

surveillance 
Rather  than  waiting  to  resolve  an  offline  pump,  Schlumberger 
can  now  shorten  the  time  it  is  offline  by  performing  what  
is needed to keep it running efficiently.

Since 2014, these processes have generated approximately 10%  
of  year-on-year  savings  in  both  capital  expenditures  and  
maintenance  costs.  This  represents  only  one  example  of  how 
digitizing planning and logistics across all functions and product 
lines can improve efficiency and lower the cost per barrel.

During hydraulic fracturing operations, different types of sensors 
placed  on  the  high-pressure  pumps  enable  Schlumberger  to  
use  data  analytics  to  predict  the  onset  of  major  component  
failures  before  they  occur.  The  data  is  collected  by  a  remote 
monitoring  center  where  experts  alert  field  personnel   
to remove a pump from operations and perform the necessary  
maintenance  before  it  fails,  which  significantly  reduces  
maintenance  costs  as  well  as  the  need  for  backup  equipment  
on location. 

Another  aspect  of  TLM  is  a  suite  of  maintenance  applications 
that  are  part  of  the  Schlumberger  Maintenance  Tool  
Ecosystem.  For  example,  at  a  fracturing  wellsite  in  North 
America  land,  two  shifts  of  crew  members  perform   
thousands of checks per day. Historically, all the data was recorded 
by hand. Today, using a highly visual mobile app, maintenance  
crew  members  can  perform  these  checks  with  significant 
improvement in their productivity.

Data  from  the  mobile  app  is  shared  in  the  cloud  along   
with  information  from  equipment  sensors,  remote  monitoring 
sites, and maintenance centers. Inventory tracking and reliability 
data  also  feed  into  the  cloud  to  facilitate  predictive  health 
maintenance. This ecosystem was deployed globally in 2017 for 
Well Services but is also being used in other product lines.

Schlumberger-Doll  
Research Center 

Schlumberger has always held the conviction that research is an 
investment in its future and an essential part of the company’s 
culture.  The  first  Schlumberger  research  laboratory,  founded 
in  1948  in  Ridgefield,  Connecticut,  focused  on  a  scientific 
research program assembled by scientist Henri-Georges Doll. 
The  objective  of  the  program  was  to  invent  new  subsurface 
measurements that would expand the growing Schlumberger 
wireline business.

In  1967,  the  laboratory  was  renamed  the  Schlumberger-Doll 
Research  Center  in  honor  of  Henri-Georges,  who  was  then 
the  retiring  chairman  and  had  been  the  foremost  technical 
contributor  at  Schlumberger.  In  2007,  the  center  moved  to 
a new facility in Cambridge, Massachusetts, to be closer to a 
major  research  hub,  including  world-renowned  universities 
such as the Massachusetts Institute of Technology (MIT) and  
Harvard University.

In  January  2017,  the  Schlumberger-Doll  Research  Center 
leverages  digital 
added  a  robotics  department  that 
technologies to address the challenges of oilfield operations—
from  subsea  and  surface  to  flexible  manufacturing.  
The  rise  of  robotics  and  artificial  intelligence  has  sparked  
a remarkable industrial transformation, and adopting the use  
of robotics in the oil and gas industry provides another opportunity 
to  reduce  operational  costs  while  further  improving  service  
quality and safety.

the  globe  to  adapt  emerging  robotics  technology,  such  as 
perception,  reasoning,  communication,  and  manipulation,  to 
enable system automation for oilfield applications.

OneSubsea Pore  
to Process Optimization

One  of  the  greatest  challenges  in  deepwater  oil  and  gas  
developments is controlling cost. Digital technology holds the 
promise of enabling domain experts to detect different ways 
to  reduce  cost  when  designing  a  subsea  system  from  pore  
to  process.  One  example  could  be  a  reduction  in  capital  
expenditure  by  redesigning  the  subsea  architecture  or  the 
topside production system.

OneSubsea Capital-Efficient Solutions extend market-leading 
subsea  boosting  technology  and  are  now  an  integral  part 
of  all  customer  projects.  Capital-Efficient  Solutions  have  
reduced the average lead times of subsea products by more 
than 50%, saving up to 60% in project costs. As a portfolio of 
standardized designs that leverages streamlined engineering 
and manufacturing processes, OneSubsea delivers integrated 
subsea production systems that reduce project cycle time and 
overall cost. 

At OneSubsea, early engagement with customers is essential 
to determine the best way to develop a field. Historically, this 
early engagement process can last from four to six months. 
During this time, OneSubsea and customer expert teams study 
the reservoir, looking closely at its expected flow dynamics, 
to  answer  specific  questions.  The  new  planning  software 
that Schlumberger is currently developing and testing with 
customers  will  shorten  the  time  it  takes  to  obtain  viable  
answers to all the questions that must be answered in the 
design of subsea development projects.

Our integrated teams of experts employ digital technology to 
explore multiple scenarios. To reduce the risks associated with 
complicated subsea developments, the teams need to explore 
as  many  scenarios  as  possible.  However,  the  traditional 
approach  to  development  entails  collecting  data  from  the 
customer that is used to iterate different concepts on paper 
for the field’s design. When this work takes place in a digital 
environment, multiple scenarios can be assessed in less time, 
which ultimately helps to accelerate the time to first oil.

Having  all  the  pertinent  data  from  different  domains  in   
one  integrated  model  also  facilitates  better  collaboration 
between experts. As the integrated team of experts from the 
customer and OneSubsea moves forward with planning, it will 
also  benefit  from  the  cognitive  abilities  of  this  new  subsea 
planning software.

Components  of  a  multiphase  compressor  for  subsea  processing 
applications are loaded onto a vessel in Horsøy, Norway, for delivery 
to an oil and gas field in the North Sea. OneSubsea Capital-Efficient 
Solutions deliver integrated subsea production systems that reduce 
project cycle time and overall cost.

Over  time,  monitoring  services  for  subsea  equipment  have 
expanded  to  include  production  monitoring,  such  as  real-
time flow assurance consulting to optimize field production.  
Using  software  such  as  the  PIPESIM*  steady-state  
multiphase  flow  simulator  and  OLGA*  dynamic  multiphase 
flow  simulator—both  of  which  are  available  in  the  cloud-
based  DELFI  cognitive  E&P  environment—in  combination 
with production chemistry testing and customized advisory 
services, Schlumberger can provide a complete flow assurance 
solution  for  any  type  of  oil  and  gas  operational  challenge. 
Furthermore, subsea monitoring uses all the data intelligence 
available from an operation to enable future intelligent design 
and manufacturing for new developments.

Digitally Enable End-to-End Solutions 

It is time for the E&P industry to do something it has never 
done before to achieve a genuine step change in performance. 
It needs to rise above historical attempts to make incremental 
improvements and instead completely redesign the workflows 
and  redefine  the  work  itself  with  a  clear  focus  on  efficiency 
and  consistency.  This  requires  deep  domain  knowledge  and 
operational  experience  that  Schlumberger  possesses  in  
understanding how workflows can be improved to create a more 
efficient pathway to lowering the cost per barrel.

Technology  is  the  fulcrum  on  which  the  oilfield  services  
industry  turns.  The  Schlumberger  focus  on  technology  

integration  drives  a  leading  portfolio  of  pore  to   pipeline 
products and services. We speak our customers’ language, and 
we are committed to developing the technology and aligning 
the  business  models  they  need  to  overcome  the  challenges  
they face. 

Schlumberger  leadership  in  hardware,  software,  and  domain 
expertise  has  enabled  our  customers  to  gain  access  to  new 
reserves,  increase  reservoir  recovery  and  production,  and  
maximize  their  returns.  Digital  technology  enablement  
represents  a  new  dimension  that  unlocks  further  value  for 
Schlumberger and its stakeholders.

The adoption of digital technology improves the speed at which field personnel have access to critical information during operations. For example, OneSurface 
engineers using handheld devices will be informed of live flow events from inside hydrocarbon processing plants, enabling them to take immediate action to 
maintain system health status.

invest

SPM creates alignment between Schlumberger and the asset holder and/or the operator whereby
Schlumberger receives remuneration in line with its value creation. These projects are generally focused
on developing and co-managing production of customer assets under
long-term agreements.
Schlumberger will
its own services and products, and in some cases cash, into the field
development activities and operations. Although in certain arrangements Schlumberger is paid for a
portion of the services or products it provides, generally Schlumberger will not be paid at the time of
providing its services or upon delivery of its products. Instead, Schlumberger is generally compensated
based upon cash flow generated or on a fee-per-barrel basis. This includes certain arrangements
whereby Schlumberger is only compensated based upon incremental production that it helps deliver
above a mutually agreed baseline. SPM represented less than 5% of Schlumberger’s consolidated
revenue for the year ended December 31, 2017.

Seasonality

Seasonal changes in weather and significant weather events can temporarily affect the delivery of oilfield
services. For example, the spring thaw in Canada and consequent road restrictions can affect activity levels,
while the winter months in the North Sea, Russia and China can produce severe weather conditions that can
temporarily reduce levels of activity. In addition, hurricanes and typhoons can disrupt coastal and offshore
operations. Furthermore, customer spending patterns for multiclient data, software and other oilfield services and
products generally result in higher activity in the fourth quarter of each year as clients seek to utilize their annual
budgets.

Customers and Backlog of Orders

For the year ended December 31, 2017, no single customer exceeded 10% of consolidated revenue. Other than
WesternGeco, OneSubsea and Drilling Systems businesses, Schlumberger has no significant backlog due to the
nature of its businesses. The WesternGeco backlog was $0.4 billion at December 31, 2017 (all of which is
expected to be recognized as revenue in 2018) and $0.8 billion at December 31, 2016. The combined backlog of
the OneSubsea and Drilling Systems businesses was $2.5 billion at December 31, 2017 (of which approximately
50% is expected to be recognized as revenue during 2018) and $3.1 billion at December 31, 2016.

Financial Information

Financial information by business segment and geographic area for the years ended December 31, 2017, 2016
and 2015 is provided in Note 17 of the Consolidated Financial Statements.

Item 1A. Risk Factors.

The following discussion of risk factors known to us contains important information for the understanding of our
“forward-looking statements,” which are discussed immediately following Item 7A. of this Form 10-K and
elsewhere. These risk factors should also be read in conjunction with Item 7. Management’s Discussion and
Analysis of Financial Condition and Results of Operations, and the Consolidated Financial Statements and
related notes included in this Form 10-K.

We urge you to consider carefully the risks described below, as well as in other reports and materials that we file
with the SEC and the other information included or incorporated by reference in this Form 10-K. If any of the
risks described below or elsewhere in this Form 10-K were to materialize, our business, financial condition,
results of operations, cash flows or prospects could be materially adversely affected. In such case, the trading
price of our common stock could decline and you could lose part or all of your investment. Additional risks and
uncertainties not currently known to us or that we currently deem immaterial may also materially adversely
affect our financial condition, results of operations and cash flows.

Demand for the majority of our products and services is substantially dependent on the levels of
expenditures by our customers. The oil and gas industry downturn has resulted in reduced demand for
oilfield services, which has had, and may continue to have, a material adverse impact on our financial
condition, results of operations and cash flows.

Demand for the majority of our products and services depends substantially on expenditures by our customers for
the exploration, development and production of oil and natural gas reserves. These expenditures are generally
dependent on our customers’ views of future oil and natural gas prices and are sensitive to our customers’ views
of future economic growth and the resulting impact on demand for oil and natural gas. Oil and gas prices have
declined significantly from their highs in 2014, resulting in lower expenditures by our customers. During the
downturn, many of our customers reduced or delayed their oil and gas exploration and production spending,
reducing the demand for our products and services and exerting downward pressure on the prices that we have
been able to charge. These conditions have had, and may continue to have, an adverse impact on our financial
condition, results of operations and cash flows.

Lower oil and gas prices have resulted in a reduction in cash flows for our customers. This has resulted in, and
may continue to result in, project modifications, delays and cancellations, general business disruptions, and
delays in payment of, or nonpayment of, amounts that are owed to us. These effects could have a material
adverse effect on our financial condition, results of operations and cash flows.

The prices for oil and natural gas have historically been volatile and can be affected by a variety of factors,
including:

There can be no assurance that the demand or pricing for oil and natural gas will follow historic patterns or
recover meaningfully in the near term. Continued or worsening conditions in the oil and gas industry could have
a further material adverse effect on our financial condition, results of operations and cash flows.

A significant portion of our revenue is derived from our non-United States operations, which exposes us to
risks inherent in doing business in each of the over 85 countries in which we operate.

Our non-United States operations accounted for approximately 74% of our consolidated revenue in 2017, 80% in
2016 and 76% in 2015. Operations in countries other than the United States are subject to various risks,
including:

volatility in political, social and economic conditions;

exposure to expropriation of our assets or other governmental actions;

confiscatory taxation or other adverse tax policies;

deprivation of contract rights;

trade and economic sanctions or other restrictions imposed by the United States, the European Union or
other countries;

restrictions under the United States Foreign Corrupt Practices Act (“FCPA”) or similar legislation;

restrictions on the repatriation of income or capital;

currency exchange controls;

inflation; and

currency exchange rate fluctuations and devaluations.

Our failure to comply with complex US and foreign laws and regulations could have a material adverse
effect on our operations.

We are subject to complex US and foreign laws and regulations, such as the FCPA, the U.K. Bribery Act and
various other anti-bribery and anti-corruption laws. We are also subject to trade control regulations and trade
sanctions laws that restrict the movement of certain goods to, and certain operations in, various countries or with
certain persons. Our ability to transfer people and products among certain countries is subject to maintaining
required licenses and complying with these laws and regulations. The internal controls, policies and procedures,
and employee training and compliance programs we have implemented to deter prohibited practices may not be
effective in preventing employees, contractors or agents from violating or circumventing such internal policies or
violating applicable laws and regulations. Any determination that we have violated or are responsible for
violations of anti-bribery, trade control, trade sanctions or anti-corruption laws could have a material adverse
effect on our financial condition. Violations of international and US laws and regulations or the loss of any
required licenses may result in fines and penalties, criminal sanctions, administrative remedies or restrictions on
business conduct, and could have a material adverse effect on our reputation and our business, operating results
and financial condition.

Demand for our products and services could be reduced by existing and future legislation or regulations.

Environmental advocacy groups and regulatory agencies in the United States and other countries have been
focusing considerable attention on the emissions of carbon dioxide, methane and other greenhouse gasses and

10

their potential role in climate change. Existing or future legislation and regulations related to greenhouse gas
emissions and climate change, as well as government initiatives to conserve energy or promote the use of
alternative energy sources, may significantly curtail demand for and production of fossil fuels such as oil and gas
in areas of the world where our customers operate, and thus adversely affect future demand for our products and
services. This may, in turn, adversely affect our financial condition, results of operations and cash flows.

Some international, national, state and local governments and agencies have also adopted laws and regulations or
are evaluating proposed legislation and regulations that are focused on the extraction of shale gas or oil using
hydraulic fracturing. Hydraulic fracturing is a stimulation treatment routinely performed on oil and gas wells in
low-permeability reservoirs. Specially engineered fluids are pumped at high pressure and rate into the reservoir
interval to be treated, causing cracks in the target formation. Proppant, such as sand of a particular size, is mixed
with the treatment fluid to keep the cracks open when the treatment is complete. Future hydraulic fracturing-
related legislation or regulations could limit or ban hydraulic fracturing, or lead to operational delays and
increased costs, and therefore reduce demand for our pressure pumping services. If such additional international,
national, state or local legislation or regulations are enacted, it could adversely affect our financial condition,
results of operations and cash flows.

Environmental compliance costs and liabilities could reduce our earnings and cash available for
operations.

We are subject to increasingly stringent laws and regulations relating to importation and use of hazardous
materials, radioactive materials, chemicals and explosives and to environmental protection, including laws and
regulations governing air emissions, hydraulic fracturing, water discharges and waste management. We incur,
and expect to continue to incur, capital and operating costs to comply with environmental laws and regulations.
The technical requirements of these laws and regulations are becoming increasingly complex, stringent and
expensive to implement. These laws may provide for “strict liability” for remediation costs, damages to natural
resources or threats to public health and safety. Strict liability can render a party liable for damages without
regard to negligence or fault on the part of the party. Some environmental laws provide for joint and several strict
liability for remediation of spills and releases of hazardous substances.

We use and generate hazardous substances and wastes in our operations. In addition, many of our current and
former properties are, or have been, used for industrial purposes. Accordingly, we could become subject to
material liabilities relating to the investigation and cleanup of potentially contaminated properties, and to claims
alleging personal injury or property damage as the result of exposures to, or releases of, hazardous substances. In
addition, stricter enforcement of existing laws and regulations, new laws and regulations, the discovery of
previously unknown contamination or the imposition of new or increased requirements could require us to incur
costs or become the basis for new or increased liabilities that could reduce our earnings and our cash available
for operations.

We could be subject to substantial liability claims, which could adversely affect our financial condition,
results of operations and cash flows.

The technical complexities of our operations expose us to a wide range of significant health, safety and
environmental risks. Our offerings involve production-related activities, radioactive materials, chemicals,
explosives and other equipment and services that are deployed in challenging exploration, development and
production environments. An accident involving these services or equipment, or a failure of a product, could
cause personal injury, loss of life, damage to or destruction of property, equipment or the environment, or
suspension of operations. Our insurance may not protect us against liability for certain kinds of events, including
events involving pollution, or against losses resulting from business interruption. Moreover, we may not be able
to maintain insurance at levels of risk coverage or policy limits that we deem adequate. Any damages caused by
our services or products that are not covered by insurance, or are in excess of policy limits or subject to
substantial deductibles, could adversely affect our financial condition, results of operations and cash flows.

11

If we are unable to maintain technology leadership, this could adversely affect any competitive advantage
we hold.

The oilfield service industry is highly competitive. Our ability to continually provide competitive technology and
services can impact our ability to defend, maintain or increase prices for our products and services, maintain
market share, and negotiate acceptable contract terms with our customers. If we are unable to continue to develop
and produce competitive technology or deliver it to our clients in a timely and cost-competitive manner in the
various markets we serve, it could adversely affect our financial condition, results of operations and cash flows.

Limitations on our ability to protect our intellectual property rights, including our trade secrets, could
cause a loss in revenue and any competitive advantage we hold.

Some of our products or services, and the processes we use to produce or provide them, have been granted patent
protection, have patent applications pending, or are trade secrets. Our business may be adversely affected if our
patents are unenforceable, the claims allowed under our patents are not sufficient to protect our technology, our
patent applications are denied or our trade secrets are not adequately protected. Our competitors may be able to
develop technology independently that is similar to ours without infringing on our patents or gaining access to
our trade secrets, which could adversely affect our financial condition, results of operations and cash flows.

We may be subject to litigation if another party claims that we have infringed upon its intellectual
property rights.

The tools, techniques, methodologies, programs and components we use to provide our services may infringe
upon the intellectual property rights of others. Infringement claims generally result in significant legal and other
costs, and may distract management from running our business. Royalty payments under licenses from third
parties, if available, would increase our costs. Additionally, developing non-infringing technologies would
increase our costs. If a license were not available, we might not be able to continue providing a particular service
or product, which could adversely affect our financial condition, results of operations and cash flows.

Failure to obtain and retain skilled technical personnel could impede our operations.

We require highly skilled personnel to operate and provide technical services and support for our business.
Competition for the personnel required for our businesses intensifies as activity increases. In periods of high
utilization it may become more difficult to find and retain qualified individuals. This could increase our costs or
have other adverse effects on our operations.

Severe weather conditions may adversely affect our operations.

Our business may be materially affected by severe weather conditions in areas where we operate. This may entail
the evacuation of personnel and stoppage of services. In addition, if particularly severe weather affects platforms
or structures, this may result in a suspension of activities. Any of these events could adversely affect our financial
condition, results of operations and cash flows.

Cyberattacks could have a material adverse impact on our business and results of operation.

We rely heavily on information systems to conduct our business. Although we devote significant resources to
protect our systems and data, we have experienced and will continue to experience varying degrees of cyber
incidents in the normal conduct of our business. There can be no assurance that the systems we have designed to
prevent or limit the effects of cyber incidents or attacks will be sufficient to prevent or detect such incidents or
attacks, or to avoid a material adverse impact on our systems when such incidents or attacks do occur. If our
systems for protecting against cybersecurity risks are circumvented or breached, this could result in disruptions to
our business operations, access to our financial reporting systems, the loss of access to critical data or systems
through ransomware or other attacks, or other loss, misuse or corruption of critical data and proprietary
information, including our intellectual property and customer data.

2017 Executive Overview

Schlumberger full-year 2017 revenue of $30.4 billion increased 9% year-on-year. This reflects a full year of
activity from the acquired Cameron businesses as compared to only three quarters of activity in 2016. In addition
to the impact of Cameron, revenue growth was driven by unconventional land resource developments in North
America due to the recovery in activity combined with market share gains and improved pricing, as the oil and
gas industry began to emerge from the longest and deepest downturn in 30 years.

Following two successive years of E&P investment cuts, operators increased their upstream spend in North
America by more than 30% in 2017. The increase in oil price afforded by the OPEC agreement gave US
producers a means to increase their investment in tight oil. However, apprehension related to growing US supply,
and uncertainty surrounding the duration of OPEC and Russia led production cuts held international spending to
a level 3% below 2016.

During 2017, the outlook improved for international markets, evidenced by a significant
increase in the
sanctioning of new projects. The number of final investment decisions tripled in 2017 as compared to 2016, with
75% of the new projects planned for shallow and deepwater offshore environments.

After starting the year at $55 per barrel, Brent prices fell to $44 in June and then recovered to $67 by the end of
the year. The price increase resulted from 2017 demand growth of 1.5 million barrels per day, and strong
adherence to a production agreement between OPEC and Russia, which served to reduce oil production by an
average of 1.6 million barrels per day compared to the fourth quarter of 2016. Strong demand and restricted
supply accelerated the depletion of stocks as the year progressed. By September, OECD crude and product stocks
had returned to 2015 levels.

As the oil market began to rebalance in 2017, replacement of conventional oil reserves remains a challenge. In
2017, discoveries were at an all-time low due to lower exploration activity, and more than 60% of discovered
resources were gas. Oil discoveries accounted for only 3.4 billion barrels, while about 30 billion barrels of
conventional oil is produced each year, representing a reserves replacement ratio of only 11%.

In the natural gas markets, low Henry Hub prices and flat domestic consumption allowed the US to transition
from importer to exporter of natural gas for the first time since 1957, and Liquified Natural Gas was the enabler.
Global LNG trading increased 11% year-on-year driven by demand in Asia. LNG supply growth was also strong,
with the addition of six new liquefaction trains in 2017. In today’s well-supplied market, both producers and
consumers are reluctant to invest in new projects. While the short-term market outlook remains challenged,
strong longer-term demand growth signals a future need for new LNG supply capacity.

Schlumberger’s financial performance in 2017 was driven by land activity in North America, where revenue
increased over 80% in line with the average rig count increase. Continued expansion of Schlumberger’s
hydraulic fracturing presence in North America resulted in additional fleet redeployments, which benefited the
Production Group. Drilling Group revenue in North America land increased due to the continuing high demand
for longer horizontal lateral sections in shale oil wells. Increased Cameron Surface and Drilling Systems product
sales and services also contributed to the strong financial performance in North America. North America
revenue, including offshore, grew 42% year-on-year.

International revenue decreased 2% as compared to 2016. This decline was driven by soft demand for exploration
and development-related products and services as E&P budgets remained tight. Activity in Latin American

18

decreased due to Schlumberger’s decision to align operations with cash collections in Venezuela. Robust activity
in the Middle East and Russia, driven by integrated drilling and production projects, as well as an additional
quarter of activity from the acquired Cameron businesses partially offset these decreases.

three years of unprecedented market downturn, Schlumberger has proactively sought

During the past
to
strengthen its technology offering and presence in key markets around the world. The most recent example is the
expansion of its hydraulic fracturing presence in North America land through the purchase of the US fracturing
and pump-down perforating businesses from Weatherford. In line with the challenging business environment,
over the same period Schlumberger has restructured all relevant parts of the company, in terms of both size and
organizational structure, to maximize its market competitiveness and operational agility.

With the significant changes seen in customer priorities and buying habits in recent years, Schlumberger has
continued to evaluate the present and future return prospects for all of its product lines, as it seeks to maximize
its long-term financial performance. Based on this in-depth analysis, Schlumberger identified the seismic
acquisition business as the only product line that does not meet Schlumberger’s return expectations going
forward, even after factoring in an eventual market recovery. Schlumberger has, therefore, taken the difficult
decision to exit the marine and land seismic acquisition market and instead operate the WesternGeco product line
as an asset-light business, built on its leading position within multiclient, data processing and geophysical
interpretation.

Looking at the oil market, the strong growth in demand is projected to continue in 2018, on the back of a robust
global economy. On the supply side, the extension of the OPEC- and Russia-led production cuts is already
translating into higher-than-expected inventory draws. In North America, 2018 shale oil production is set for
another year of strong growth, as the positive oil market sentiments will likely increase both investment appetite
and availability of financing. At the same time, the production base in the rest of the world is showing fatigue
after three years of unprecedented under-investment. The underlying signs of weakness will likely become more
evident in the coming year, as the production additions from investments made in the previous upcycle start to
noticeably fall off. Taken together, this means the oil market is now in balance and the previous over-supply
discount is gradually being replaced by a market tightness premium, which makes Schlumberger increasingly
positive on the global outlook for its business.

These positive oil market sentiments are reflected in third-party E&P spend surveys that predict 15-20% growth
in North American investments in 2018, while the international market is expected to grow for the first time in
four years, with a projected 5% increase in spend. As a result, as Schlumberger enters the first year of expected
growth in all parts of its global operations since 2014, there is a renewed excitement and enthusiasm throughout
the organization, and Schlumberger remains committed to delivering market-leading products and services to its
customers and superior returns to its shareholders.

managed initiatives and other nonoperating items. Full-year 2017 and 2016 include $252 million and
$189 million, respectively, of amortization expense associated with intangible assets recorded as a result of
the acquisition of Cameron, which was completed on April 1, 2016.

Full-year 2017 revenue of $30.4 billion increased 9% year-on-year. This included a full year of activity from the
acquired Cameron businesses versus nine months of activity for the same period in 2016. Excluding the impact
of the Cameron Group, revenue increased 7% year-on-year. The growth was primarily driven by North America,
where the land rig count increased more than 80% versus the same period last year.

Full-year revenue for the Drilling Group declined 2% primarily driven by the 8% decline in offshore rig count
combined with Schlumberger’s decision in April 2016 to reduce its activities in Venezuela to align operations
with cash collections. Production Group revenue increased 21% due to the accelerated land pressure pumping
activity growth in North America, while the Reservoir Characterization Group revenue improved 2%.

Full-year 2017 pretax operating margin was expanded 111 basis points (“bps”) to 13%, as improved profitability
in North America due to the land activity growth that benefited the Production and Drilling Groups was offset by
margin declines in the Reservoir Characterization and Cameron Groups.

Reservoir Characterization Group

Full-year 2017 revenue of $6.8 billion increased 2% year-on-year primarily due to higher WesternGeco and
Wireline revenue on projects in the Middle East & Asia Area, North America land, Russia and Mexico.

Year-on-year, pretax operating margin was essentially flat at 18%.

20

Drilling Group

Full-year 2017 revenue of $8.4 billion decreased 2% year-on-year primarily due to the rig count declines
internationally and in offshore North America combined with pricing pressure. Revenue also declined as a result
of Schlumberger’s decision in April 2016 to reduce its activities in Venezuela to align operations with cash
collections.

Year-on-year, pretax operating margin increased 210 bps to 14% primarily due to improved profitability in North
America due to accelerated land activity and improved pricing. This improvement was partially offset by the
negative impact of reduced activity in Venezuela.

Production Group

Full-year 2017 revenue of $10.6 billion increased 21% year-on-year with most of the revenue increase
attributable to the accelerated land activity growth in North America that benefited the pressure pumping
business which grew 44%. Lower Schlumberger Production Management (SPM) production levels in Ecuador
partially offset the revenue increase.

Year-on-year, pretax operating margin increased 297 bps to 9% as a result of improved profitability in North
America due to the accelerated land activity and improved pricing. This was partially offset by reduced margins
in SPM due to lower production in Ecuador.

Cameron Group

The Cameron Group contributed full-year revenue of $5.2 billion. Cameron Group revenue for 2016 included
only nine months of revenue following the closing of the acquisition in April 2016. Revenue in 2017 was
impacted by a declining project backlog, particularly for the long-cycle businesses of Drilling Systems and
OneSubsea.

Year-on-year, pretax operating margin of 14% decreased 142 bps as a result of lower Drilling Systems project
volumes.

Full-year 2016 revenue of $27.8 billion decreased 22% year-on-year. This included nine months of activity from
the Cameron Group, which contributed $4.2 billion of revenue.

Full-year 2016 revenue from both the Reservoir Characterization and Production Groups declined by 30%, as a
result of lower demand for exploration- and development-related products and services as E&P budgets were
further reduced. Drilling Group revenue fell 37% due to the rig count decline in both North America and
internationally.

Full-year 2016 pretax operating income margin decreased 658 bps to 12% as a result of the overall decline in
activity and pervasive pricing concessions. The margin decrease was highest in the Reservoir Characterization
Group, which contracted by 699 bps to 19%. Drilling Group pretax operating margin fell 710 bps to 12%, while
the Production Group decreased 687 bps to 6%. The Cameron Group posted a pretax margin of 16%.

Reservoir Characterization Group

Full-year 2016 revenue of $6.7 billion decreased 30% year-on-year primarily due to sustained cuts in exploration
and discretionary spending.

Year-on-year, pretax operating margin decreased 699 bps to 19% due to reduced high-margin Wireline and
Testing Services activities.

Drilling Group

Full-year 2016 revenue of $8.6 billion decreased 37% year-on-year primarily due to the severe drop in rig count
in both North America and internationally combined with pricing pressure that mainly affected Drilling &
Measurements and M-I SWACO activity.

Year-on-year, pretax operating margin decreased 710 bps to 12% primarily due to the significant decline in
higher-margin activities of Drilling & Measurements combined with pricing weakness.

Production Group

Full-year 2016 revenue of $8.7 billion decreased 30% year-on-year with most of the decrease attributable to a
decline in North America, particularly on Well Services pressure pumping technologies driven by activity
declines and pricing pressure as the land rig count declined dramatically.

Year-on-year, pretax operating margin decreased 687 bps to 6% as a result of lower activity and increasing
pricing pressure, which continued to impact North America land.

Cameron Group

Cameron Group contributed nine-month revenue of $4.2 billion and pretax operating margin of 16%. Revenue
was impacted by a declining project backlog as well as a further slowdown in North America land activity, which
also affected the short-cycle businesses of the Valves & Measurement and Surface product lines.

22

Pretax operating margin of 16% was driven by strong project execution and manufacturing efficiency in
OneSubsea and overall cost control across the Group.

The increase in interest income in 2016 as compared to 2015 is primarily attributable to the higher cash and
short-term investment balances as a result of the issuance of $6.0 billion of Senior Notes during the fourth
quarter of 2015.

The decrease in earnings of equity method investments in 2016 as compared to 2015 primarily reflects the effects
of the downturn in the oil and gas industry, which has negatively impacted the majority of Schlumberger’s
that
investments in affiliates, particularly those in North America. This decrease also reflects the fact
Schlumberger ceased recording equity income from the OneSubsea joint venture in April 2016 as a result of
Schlumberger’s acquisition of Cameron.

Interest Expense

Interest expense of $566 million in 2017 was essentially flat as compared to 2016.

Interest expense of $570 million in 2016 increased by $224 million compared to 2015 primarily due to the
issuance of $6.0 billion of Senior Notes during the fourth quarter of 2015 and the impact of the $3.0 billion of
debt assumed in the acquisition of Cameron.

Research & engineering costs have decreased in terms of both absolute dollars and as a percentage of Revenue in
2017 as compared to 2016 as a result of cost control measures.

Although Research & engineering costs increased as a percentage of Revenue in 2016 as compared to 2015, they
decreased in absolute dollar terms as a result of cost control measures that were implemented, offset in part by
the impact of the Cameron acquisition.

Income Taxes

The Schlumberger effective tax rate was (27.9)% in 2017, 14.6% in 2016, and 25.9% in 2015.

23

The Schlumberger effective tax rate has historically been sensitive to the geographic mix of earnings. When the
percentage of pretax earnings generated outside of North America increased, the Schlumberger effective tax rate
generally decreased. Conversely, when the percentage of pretax earnings generated outside of North America
decreased, the Schlumberger effective tax rate generally increased.

The effective tax rate for each of 2017, 2016 and 2015 was significantly impacted by the charges and credits
described in Note 3 to the Consolidated Financial Statements because they were only partially tax-effective.
Excluding the impact of these charges and credits, the effective tax rate was 18.2% in 2017, 15.9% in 2016 and
20.2% in 2015. The increase in the effective tax rate in 2017 as compared to 2016, excluding the impact of
charges and credits, was primarily attributable to a change in the geographic mix of earnings as the percentage of
pretax earnings generated in North America increased. The decrease in the effective tax rate, excluding the
impact of charges and credits, in 2016 as compared to 2015 was primarily attributed to the geographic mix of
earnings and the favorable resolution of the tax examinations in certain jurisdictions.

As discussed in further detail in Note 3 to the Consolidated Financial Statements, on December 22, 2017 the US
enacted the Tax Cuts and Jobs Act (the “Act”). The Act, which is also commonly referred to as “US tax reform”,
significantly changes US corporate income tax laws by, among other things, reducing the US corporate income
tax rate to 21% starting in 2018 and creating a territorial tax system with a one-time mandatory tax on previously
deferred foreign earnings of US subsidiaries.

Excluding the impact of any discrete items, the provisions of the Act are expected to reduce Schlumberger’s
effective tax rate in 2018 by approximately 2 to 3 percentage points compared to what the rate would have
otherwise been in the absence of US tax reform. The ultimate impact on Schlumberger’s effective tax rate will
largely depend on the percentage of pretax earnings that Schlumberger generates in the US as compared to the
rest of the world.

Charges and Credits

Schlumberger recorded significant charges and credits during 2017, 2016 and 2015. These charges and credits,

“Net Debt” represents gross debt less cash, short-term investments and fixed income investments, held to maturity.
Management believes that Net Debt provides useful information regarding the level of Schlumberger’s indebtedness by
reflecting cash and investments that could be used to repay debt. Net Debt is a non-GAAP financial measure that should
be considered in addition to, not as a substitute for, or superior to, total debt.
Includes depreciation of property, plant and equipment and amortization of intangible assets, multiclient seismic data
costs and SPM investments.
Includes severance payments of approximately $455 during 2017, $850 million during 2016 and $810 million during
2015.
“Free cash flow” represents cash flow from operations less capital expenditures, SPM investments and multiclient
seismic data costs capitalized. Management believes that free cash flow is an important liquidity measure for the
company and that it is useful to investors and management as a measure of the ability of our business to generate cash.
Once business needs and obligations are met, this cash can be used to reinvest in the company for future growth or to
return to shareholders through dividend payments or share repurchases. Free cash flow does not represent the residual
cash flow available for discretionary expenditures. Free cash flow is a non-GAAP financial measure that should be
considered in addition to, not as substitute for, or superior to, cash flow from operations.

Cash flow from operations was $5.7 billion in 2017, $6.3 billion in 2016 and $8.8 billion in 2015. The
decrease in operating cash flows for each of the last two years is largely attributable to lower earnings
before non-cash charges and credits and depreciation and amortization expense.

Schlumberger paid $2.8 billion of cash in connection with its acquisition of Cameron. Additionally, as a
result of the acquisition of Cameron, Schlumberger assumed $3.0 billion of debt (including a
$244 million adjustment to increase Cameron’s long-term fixed rate debt to its estimated fair value) and
acquired $2.2 billion of cash and short-term investments.

During the second quarter of 2016, Schlumberger repurchased approximately $1.4 billion of Cameron’s
long-term fixed-rate debt.

In connection with Schlumberger’s acquisition of Cameron, Cameron merged with Schlumberger
Holdings Corporation (“SHC”), an indirect wholly-owned United States subsidiary of Schlumberger.
Under the terms of the agreement, Cameron shareholders received 0.716 shares of Schlumberger
Limited common stock and a cash payment of $14.44 in exchange for each Cameron share of common
stock outstanding. In connection with this transaction, SHC acquired approximately 138 million shares
of common stock from Schlumberger Limited and transferred those shares to Cameron’s shareholders.

In order to partially fund the purchase of the 138 million shares of common stock from Schlumberger
Limited that were transferred to Cameron stockholders, SHC issued $6 billion of notes during the fourth
quarter of 2015 consisting of the following:

–

$500 million of 1.90% Senior Notes due 2017;
$1.3 billion of 2.35% Senior Notes due 2018;

$850 million of 3.63% Senior Notes due 2022; and
$1.75 billion of 4.00% Senior Notes due 2025.

On July 18, 2013, the Board approved a new $10 billion share repurchase program to be completed at
the latest by June 30, 2018. This program was completed during May 2017. On January 21, 2016, the
Board approved a new $10 billion share repurchase program for Schlumberger common stock.
Schlumberger had repurchased $324 million under the new program as of December 31, 2017.

Dividends paid during 2017, 2016 and 2015 were $2.8 billion, $2.6 billion and $2.4 billion, respectively.

Capital expenditures were $2.1 billion in 2017, $2.1 billion in 2016 and $2.4 billion in 2015. Capital
expenditures are expected to be approximately $2.1 billion in 2018.

During the fourth quarter of 2017, Schlumberger issued $0.5 billion of 2.20% Guaranteed Notes due
2020 and $0.6 billion of 2.65% Guaranteed Notes due 2022.

During 2017, 2016 and 2015 Schlumberger made contributions of $133 million, $174 million and
$346 million, respectively, to its postretirement benefit plans. The US pension plans were 88% funded
at December 31, 2017 and 85% funded at December 31, 2016 based on the projected benefit obligation.

29

Schlumberger’s international defined benefit pension plans were a combined 97% funded at
December 31, 2017 based on the projected benefit obligation. This compares to 92% funded at
December 31, 2016.

Schlumberger expects to contribute approximately $125 million to its postretirement benefit plans in
2018, subject to market and business conditions.

(cid:129)

The increase in SPM investments in 2017 as compared to 2016 is primarily attributable to the purchase
of a majority non-operating interest in the Palliser Block, located in Alberta, Canada, from Cenovous
Energy, an integrated Canadian oil company.

Schlumberger maintains a €5.0 billion Guaranteed Euro Medium Term Note program. This program provides for
the issuance of various types of debt instruments such as fixed or floating rate notes in Euro, US dollar or other
currencies. Schlumberger has issued €0.5 billion 1.50% Guaranteed Notes due 2019 under this program.

As of December 31, 2017, Schlumberger had $5.1 billion of cash and short-term investments on hand.
Schlumberger also has separate committed credit facility agreements aggregating $6.6 billion with commercial
banks, of which $3.6 billion was available and unused as of December 31, 2017. The $6.6 billion of committed
credit facility agreements included $6.3 billion of committed facilities which support commercial paper
programs. Schlumberger believes that these amounts are sufficient to meet future business requirements for at
least the next 12 months.

The total outstanding commercial paper borrowings were $3.0 billion as of December 31, 2017 and $2.6 billion
as of December 31, 2016.

Refer to Note 18, Pension and Other Benefit Plans, of the Consolidated Financial Statements for details
regarding Schlumberger’s pension and other postretirement benefit obligations.

As discussed in Note 14, Income Taxes, of the Consolidated Financial Statements, included in the Schlumberger
Consolidated Balance Sheet at December 31, 2017 is approximately $1.4 billion of liabilities associated with
uncertain tax positions in the over 100 jurisdictions in which Schlumberger conducts business. Due to the

30

uncertain and complex application of tax regulations, combined with the difficulty in predicting when tax audits
throughout the world may be concluded, Schlumberger cannot make reliable estimates of the timing of cash
outflows relating to these liabilities.

Schlumberger has outstanding letters of credit/guarantees that relate to business performance bonds, custom/
excise tax commitments, facility lease/rental obligations, etc. These were entered into in the ordinary course of
business and are customary practices in the various countries where Schlumberger operates.

Critical Accounting Policies and Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles
generally accepted in the United States requires Schlumberger to make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported
amounts of revenue and expenses. The following accounting policies involve “critical accounting estimates”
because they are particularly dependent on estimates and assumptions made by Schlumberger about matters that
are inherently uncertain.

Schlumberger bases its estimates on historical experience and on various assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for making judgments about the carrying
values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from
these estimates under different assumptions or conditions.

Multiclient Seismic Data

Schlumberger capitalizes the costs associated with obtaining multiclient seismic data. The carrying value of the
multiclient seismic data library at December 31, 2017 and 2016 was $727 million and $1.07 billion, respectively.
Such costs are charged to Cost of services based on the percentage of the total costs to the estimated total revenue
that Schlumberger expects to receive from the sales of such data. However, under no circumstances will an
individual survey carry a net book value greater than a 4-year, straight-line amortized value.

The carrying value of surveys is reviewed for impairment annually as well as when an event or change in
circumstance indicates an impairment may have occurred. Adjustments to the carrying value are recorded when it
is determined that estimated future revenues, which involve significant judgment on the part of Schlumberger,
would not be sufficient
to recover the carrying value of the surveys. Significant adverse changes in
Schlumberger’s estimated future cash flows could result in impairment charges in a future period. For purposes
of performing the annual
library, surveys are primarily analyzed for
impairment
impairment on a survey-by-survey basis.

test of the multiclient

Allowance for Doubtful Accounts

Schlumberger maintains an allowance for doubtful accounts in order to record accounts receivable at their net
realizable value. Judgment is involved in recording and making adjustments to this reserve. Allowances have
been recorded for receivables believed to be uncollectible, including amounts for the resolution of potential credit
and other collection issues such as disputed invoices. Adjustments to the allowance may be required in future
periods depending on how such potential issues are resolved, or if the financial condition of Schlumberger’s
customers were to deteriorate resulting in an impairment of their ability to make payments.

As a large multinational company with a long history of operating in a cyclical industry, Schlumberger has
extensive experience in working with its customers during difficult times to manage its accounts receivable.
During weak economic environments or when there is an extended period of weakness in oil and gas prices,
Schlumberger typically experiences delays in the payment of its receivables. However, except as described
below, Schlumberger has not had material write-offs due to uncollectible accounts receivable over the recent

31

industry downturn. Schlumberger operates in more than 85 countries. As of December 31, 2017, only five of
those countries individually accounted for greater than 5% of Schlumberger’s net receivables balance, of which
only one (the United States) accounted for greater than 10% of such receivables.

During the second quarter of 2017, Schlumberger entered into a financing agreement with its primary customer
in Venezuela. This agreement resulted in the exchange of $700 million of outstanding accounts receivable for
promissory notes with a three-year term that bear interest at the rate of 6.50% per annum. Schlumberger recorded
these notes at their estimated fair value on the date of the exchange, which resulted in a pretax and after-tax
charge of $460 million. As a result, the cost basis of the promissory note was $240 million as of June 30, 2017.

In April 2016, Schlumberger announced that it was reducing its activity in Venezuela to align operations with
cash collections as a result of insufficient payments on outstanding receivables. Schlumberger also previously
disclosed that its judgment regarding the collectibility of its receivables and promissory notes in Venezuela is
sensitive to the political and economic conditions in the country and that, if conditions in Venezuela worsen,
Schlumberger may be required to record adjustments to the carrying value of these assets. During the fourth
quarter of 2017, conditions in Venezuela further deteriorated such that Schlumberger determined it was
appropriate to write-off the remaining outstanding receivable balance of approximately $469 million and record
an impairment charge of $105 million related to the aforementioned promissory notes, in order to write-down the
cost basis of such notes to their estimated fair value as of December 31, 2017.

Goodwill, Intangible Assets and Long-Lived Assets

Schlumberger records the excess of purchase price over the fair value of the tangible and identifiable intangible
assets acquired and liabilities assumed as goodwill. The goodwill relating to each of Schlumberger’s reporting
units is tested for impairment annually as well as when an event, or change in circumstances, indicates an
impairment may have occurred.

Under generally accepted accounting principles, Schlumberger has the option to first assess qualitative factors to
determine whether the existence of events or circumstances leads to a determination that it is more likely than not
that the fair value of one of its reporting units is greater than its carrying amount. If, after assessing the totality of
events or circumstances, Schlumberger determines it is more likely than not that the fair value of a reporting unit
is greater than its carrying amount, there is no need to perform any further testing. However, if Schlumberger
concludes otherwise, then it is required to perform a quantitative impairment test by calculating the fair value of
the reporting unit and comparing the fair value with the carrying amount of the reporting unit. If the fair value of
the reporting unit is less than its carrying value, an impairment loss is recorded based on that difference.

Schlumberger has the option to bypass the qualitative assessment for any reporting unit in any period and
proceed directly to performing the quantitative goodwill impairment test.

For purposes of performing the impairment test for goodwill, Schlumberger’s reporting units are its four Groups:
Reservoir Characterization, Drilling, Production and Cameron. Schlumberger elected to perform the qualitative
assessment described above for purposes of its annual goodwill impairment
test in 2017. Based on this
assessment, Schlumberger concluded that it was more likely than not that the fair value of each of its reporting
units was greater than its carrying amount. Accordingly, no further testing was required.

Long-lived assets, including fixed assets, intangible assets and investments in SPM projects, are reviewed for
impairment whenever events or changes in circumstances indicate that
the carrying value may not be
recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated
undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash
flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the
carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as
the estimated fair value of long-lived assets involves significant estimates on the part of management. If there is a

32

material change in economic conditions or other circumstances influencing the estimate of future cash flows or
fair value, Schlumberger could be required to recognize impairment charges in the future.

Income Taxes

Schlumberger conducts business in more than 100 tax jurisdictions, a number of which have tax laws that are not
fully defined and are evolving. Schlumberger’s tax filings are subject to regular audits by the tax authorities.
These audits may result in assessments for additional taxes that are resolved with the authorities or, potentially,
through the courts. Schlumberger recognizes the impact of a tax position in its financial statements if that
position is more likely than not of being sustained on audit, based on the technical merits of the position. Tax
liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these
audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes
in facts and circumstances. However, due to the uncertain and complex application of tax regulations, the
ultimate resolution of audits may result in liabilities that could be materially different from these estimates. In
such an event, Schlumberger will record additional tax expense or tax benefit in the period in which such
resolution occurs.

Percentage-of-Completion Revenue Recognition

Schlumberger uses the percentage-of-completion method to account for certain long-term construction-type
contracts. These contracts involve significant design and engineering efforts in order to satisfy custom designs
for customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work
progresses on each contract. Progress is measured by the ratio of actual costs incurred to date on the project in
relation to total estimated project costs.

The estimate of total project costs has a significant impact on both the amount of revenue recognized as well as
the related profit on a project. Revenue and profits on contracts can also be significantly affected by change
orders and claims. Profits are recognized based on the estimated project profit multiplied by the percentage
complete. Due to the nature of these projects, adjustments to estimates of contract revenue and total contract
costs are often required as work progresses. Any expected losses on a project are recorded in full in the period in
which they become probable.

Approximately 7% of Schlumberger’s revenue in 2017 was recognized under the percentage-of-completion
method.

Pension and Postretirement Benefits

Schlumberger’s pension and postretirement benefit obligations are described in detail
in Note 18 to the
Consolidated Financial Statements. The obligations and related costs are calculated using actuarial concepts,
which include critical assumptions related to the discount rate, expected rate of return on plan assets and medical
cost trend rates. These assumptions are important elements of expense and/or liability measurement and are
updated on an annual basis, or upon the occurrence of significant events.

The discount rate that Schlumberger uses reflects the prevailing market rate of a portfolio of high-quality debt
instruments with maturities matching the expected timing of payment of the related benefit obligations. The
following summarizes the discount rates utilized by Schlumberger for its various pension and postretirement
benefit plans:

(cid:129)

(cid:129)

The discount rate utilized to determine the liability for Schlumberger’s United States pension plans
and postretirement medical plan was 3.70% at December 31, 2017 and 4.20% at December 31, 2016.

The weighted-average discount

The weighted-average discount rate utilized to determine expense for Schlumberger’s United States
pension plans and postretirement medical plan decreased from 4.50% in 2016 to 4.20% in 2017.

The weighted-average discount rate utilized to determine expense for Schlumberger’s international
pension plans decreased from 4.36% in 2016 to 4.13% in 2017.

The expected rate of return for Schlumberger’s retirement benefit plans represents the average rate of return
expected to be earned on plan assets over the period that benefits included in the benefit obligation are expected
to be paid. The expected rate of return for Schlumberger’s United States pension plans has been determined
based upon expected rates of return for the investment portfolio, with consideration given to the distribution of
investments by asset class and historical rates of return for each individual asset class. The weighted average
expected rate of return on plan assets for the United States pension plans was 7.25% in both 2017 and 2016. The
weighted average expected rate of return on plan assets for the international pension plans was 7.40% in both
2017 and 2016. A lower expected rate of return would increase pension expense.

Schlumberger’s medical cost trend rate assumptions are developed based on historical cost data, the near-term
outlook and an assessment of likely long-term trends. The overall medical cost trend rate assumption utilized to
determine the 2017 postretirement medical expense was 7.25% graded to 5.0% over the next nine years. The
overall medical trend rate assumption utilized to determine the postretirement medical liability at December 31,
2017 was 7.25% graded to 5.0% over the next nine years.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Schlumberger is subject to market risks primarily associated with changes in foreign currency exchange rates and
interest rates.

As a multinational company, Schlumberger operates in more than 85 countries. Schlumberger’s functional
currency is primarily the US dollar. Approximately 78% of Schlumberger’s revenue in 2017 was denominated in
US dollars. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in
foreign currencies. Therefore, when the US dollar weakens in relation to the foreign currencies of the countries in
which Schlumberger conducts business, the US dollar-reported expenses will increase.

Schlumberger maintains a foreign-currency risk management strategy that uses derivative instruments to manage
the impact of changes in foreign exchange rates on its earnings. Schlumberger enters into foreign currency
forward contracts to provide a hedge against currency fluctuations on certain monetary assets and liabilities, and
certain expenses denominated in currencies other than the functional currency.

A 10% appreciation in the US dollar from the December 31, 2017 market rates would increase the unrealized
value of Schlumberger’s forward contracts by $123 million. Conversely, a 10% depreciation in the US dollar
from the December 31, 2017 market rates would decrease the unrealized value of Schlumberger’s forward
contracts by $74 million. In either scenario, the gain or loss on the forward contract would be offset by the gain
or loss on the underlying transaction, and therefore, would have no impact on future earnings.

At December 31, 2017, contracts were outstanding for the US dollar equivalent of $5.0 billion in various foreign
currencies of which $1.8 billion related to hedges of debt balances denominated in currencies other than the
functional currency.

Schlumberger is subject to interest rate risk on its debt and its investment portfolio. Schlumberger maintains an
interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its
investment portfolio and occasionally interest rate swaps to mitigate the exposure to changes in interest rates. At
December 31, 2017, Schlumberger had fixed rate debt aggregating approximately $14.2 billion and variable rate
debt aggregating approximately $4.0 billion, before considering the effects of cross currency swaps.

Schlumberger’s exposure to interest rate risk associated with its debt is also partially mitigated by its investment
portfolio. Short-term investments, which totaled approximately $3.3 billion at December 31, 2017, is comprised
primarily of money market funds, time deposits, certificates of deposit, commercial paper, bonds and notes,
substantially all of which are denominated in US dollars. The average return on investments was 1.3% in 2017.

2. Summary of Accounting Policies

The Consolidated Financial Statements of Schlumberger have been prepared in accordance with accounting
principles generally accepted in the United States of America.

Use of Estimates

The preparation of financial statements requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis,
Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable; revenue
recognized under the percentage-of-completion method; recoverability of fixed assets, goodwill, intangible
assets, Schlumberger Production Management
income taxes;
multiclient seismic data; contingencies and actuarial assumptions for employee benefit plans. Schlumberger
bases its estimates on historical experience and other assumptions that are believed to be reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under
different assumptions or conditions.

investments and investments in affiliates;

Revenue Recognition

Schlumberger recognizes revenue based upon purchase orders, contracts or other persuasive evidence of an
arrangement with the customer that include fixed or determinable prices provided that collectibility is reasonably
assured. Revenue is recognized for services when they are rendered. Revenue is recognized for products upon
delivery and when the customer assumes the risks and rewards of ownership.

Revenue is recognized for certain long-term construction-type contracts based on the percentage-of-completion
method. These contracts involve significant design and engineering efforts in order to satisfy custom designs for
customer-specific applications. Under the percentage-of-completion method, revenue is recognized as work
progresses on each such contract. Progress is measured by the ratio of actual costs incurred to date on the project
in relation to total estimated project costs. Any expected losses on a project are recorded in full in the period in
which they become probable. Progress billings are generally issued upon completion of certain phases of work as
stipulated in the contract. Revenue in excess of billings is included within Receivables less allowance for
doubtful accounts in the Consolidated Balance Sheet. Billings and cash collections in excess of revenue
recognized on contracts are included within Accounts payable and accrued liabilities in the Consolidated
Balance Sheet.

Revenue from seismic contract services performed on a dayrate basis is recognized as the service is performed.
Revenue from other services, including pre-funded multiclient surveys, is recognized as the seismic data is
acquired and/or processed on a proportionate basis as work is performed. This method requires revenue to be
recognized based upon quantifiable measures of progress, such as square kilometers acquired. Multiclient data
surveys are licensed or sold to customers on a non-transferable basis. Revenue from sales of completed
multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers with
access to such data.

44

Revenue is occasionally generated from contractual arrangements that include multiple deliverables. Revenue
from these arrangements is recognized as each item is delivered based on its relative fair value, provided that the
delivered items have stand-alone value to the customer.

Revenue derived from the sale of licenses of Schlumberger software may include installation, maintenance,
consulting and training services. If services are not essential to the functionality of the software, the revenue for
each element of the contract is recognized separately based on its respective vendor specific objective evidence
of fair value when all of the following conditions are met: a signed contract is obtained, delivery has occurred,
the fee is fixed or determinable and collectibility is probable.

Short-term Investments

The Consolidated Balance Sheet reflects the Schlumberger investment portfolio separated between current and
long term, based on maturity. Short-term investments are comprised primarily of money market funds, time
deposits, certificates of deposit, commercial paper, bonds and notes, substantially all of which are denominated
in US dollars and are stated at cost plus accrued interest, which approximates market.

For purposes of the Consolidated Statement of Cash Flows, Schlumberger does not consider Short-term
investments to be cash equivalents.

Investments in Affiliated Companies

Investments in companies in which Schlumberger does not have a controlling financial interest, but over which it
has significant influence, are accounted for using the equity method. Schlumberger’s share of the after-tax
earnings of equity method investees is included in Interest and other income. Investments in privately held
companies in which Schlumberger does not have the ability to exercise significant influence are accounted for
using the cost method. Investments in publicly traded companies in which Schlumberger does not have
significant influence are accounted for as available-for-sale marketable securities, reported at fair value with
unrealized gains and losses reported as a component of Accumulated other comprehensive loss.

Equity and cost method investments as well as investments in available-for-sale marketable securities are
classified as Investments in Affiliated Companies in the Consolidated Balance Sheet.

Multiclient Seismic Data

Schlumberger’s multiclient library consists of completed and in-process seismic surveys that are licensed on a
nonexclusive basis. Schlumberger capitalizes costs directly incurred in acquiring and processing the multiclient
seismic data. Such costs are charged to Cost of services based on the percentage of the total costs to the estimated
total revenue that Schlumberger expects to receive from the sales of such data. However, under no circumstance
will an individual survey carry a net book value greater than a 4-year, straight-line amortized value.

The carrying value of the multiclient library is reviewed for impairment annually as well as when an event or
change in circumstance indicating impairment may have occurred. Adjustments to the carrying value are
recorded when it is determined that estimated future cash flows, which involve significant judgment on the part
of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse
changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period.

Schlumberger Production Management

Schlumberger Production Management (“SPM”) projects are focused on developing and managing production on
behalf of Schlumberger’s clients under long-term agreements. Schlumberger will invest its own services and
products, and in some cases cash, into the field development activities and operations. Although in certain

45

arrangements Schlumberger is paid for a portion of the services or products it provides, generally Schlumberger
will not be paid at the time of providing its services or upon delivery of its products. Instead, Schlumberger is
compensated based upon cash flow generated or on a fee-per-barrel basis. This includes certain arrangements
whereby Schlumberger is only compensated based upon incremental production it helps deliver above a mutually
agreed baseline.

Revenue from SPM arrangements, which is recognized as the related production is achieved, represented less
than 5% of Schlumberger’s consolidated revenue during each of 2017, 2016 and 2015.

Schlumberger capitalizes its cash investments in a project as well as the direct costs associated with providing
services or products for which Schlumberger will be compensated when the related production is achieved. These
capitalized investments are amortized to the Consolidated Statement of Income (Loss) as the related production is
achieved based on the units of production method, whereby each unit produced is assigned a pro-rata portion of
the unamortized costs based on estimated total production, resulting in a matching of revenue with the applicable
costs. Amortization expense relating to these capitalized investments was $465 million, $449 million and
$317 million in 2017, 2016 and 2015, respectively.

During 2017, Schlumberger purchased a majority non-operating interest in the Palliser Block, located in Alberta,
Canada. In connection with the initial accounting for this transaction, Schlumberger recorded a $268 million
asset retirement obligation, which was included in both Other Assets and Other Liabilities in the Consolidated
Balance Sheet.

The unamortized portion of Schlumberger’s investments in SPM projects was $4.065 billion and $2.458 billion at
December 31, 2017 and 2016, respectively. These amounts are included within Other Assets in Schlumberger’s
Consolidated Balance Sheet.

Concentration of Credit Risk

Schlumberger’s assets that are exposed to concentrations of credit risk consist primarily of cash, short-term
investments, fixed income investments held to maturity, receivables from clients and derivative financial
instruments. Schlumberger places its cash, short-term investments and fixed income investments held to maturity
with financial institutions and corporations and limits the amount of credit exposure with any one of them.
Schlumberger regularly evaluates the creditworthiness of the issuers in which it invests. By using derivative
financial instruments to hedge certain exposures, Schlumberger exposes itself to some credit risk. Schlumberger
minimizes this credit risk by entering into transactions with high-quality counterparties, limiting the exposure to
each counterparty and monitoring the financial condition of its counterparties.

Schlumberger operates in more than 85 countries and as such, its accounts receivable are spread over many
countries and customers. Accounts receivable in the United States represented approximately 23% of
Schlumberger’s accounts receivable balance at December 31, 2017. No other country accounted for greater than
10% of Schlumberger’s accounts receivable balance.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU)
2014-09, Revenue from Contracts with Customers. This ASU amends the existing accounting standards for
revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of
goods or services to a customer at an amount that reflects the consideration a company expects to receive in
exchange for those goods or services. Schlumberger adopted this ASU on January 1, 2018. Schlumberger has
concluded that the adoption of this ASU will not have a material impact on its consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU requires lessees to recognize a right of
use asset and lease liability on the balance sheet for all leases, with the exception of short-term leases.

47

Schlumberger will adopt this ASU on January 1, 2019. Based on its current lease portfolio, Schlumberger
estimates that the adoption of this ASU will result in approximately $1.2 billion of additional assets and liabilities
being reflected on its Consolidated Balance Sheet.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation.

3. Charges and Credits

Schlumberger recorded the following charges and credits during 2017, 2016 and 2015:

During the fourth quarter of 2017, Schlumberger decided to cease all future marine seismic acquisition
activities, after satisfying its remaining contractual commitments. As a result, Schlumberger will seek to
monetize its existing fleet of marine seismic vessels. This decision resulted in a charge of $1.025 billion
consisting of the following: $786 million write-down of the vessels to their estimated fair value;
$78 million impairment of intangible assets; $59 million write-down of inventory, and $102 million of
other related restructuring costs. The fair value of the vessels was determined based on unobservable
inputs that required significant judgments. Schlumberger also recorded a $90 million impairment charge
relating to its land seismic business.

As a result of the unfavorable near-term outlook for exploration spending, Schlumberger determined in
the fourth quarter of 2017 that the carrying value of certain multiclient seismic data, primarily related to
the US Gulf of Mexico, was impaired, resulting in a $246 million charge that was estimated based on
the projected present value of future cash flows that these surveys are expected to generate.

During the fourth quarter of 2017, Schlumberger determined that it was appropriate to write-down its
investment in Venezuela, given the recent economic and political developments in the country which
have created significant uncertainties regarding recoverability. As a result, Schlumberger recorded a
charge of $938 million, reflecting $469 million of accounts receivable, a $105 million other-than-
temporary impairment charge relating to the promissory notes described below, $285 million of fixed
assets and $79 million of other assets in the country.

During the fourth quarter of 2017, Schlumberger recorded a $245 million charge related to an estimated

loss on a long-term surface facility construction project
percentage-of-completion method.

that

Schlumberger recorded $156 million of other restructuring charges during the fourth quarter of 2017,
primarily relating to facility and other exit costs.

During the fourth quarter of 2017, Schlumberger recorded a $247 million charge associated with
headcount reductions primarily to further streamline its support cost structure.

On December 22, 2017, the US enacted the Tax Cuts and Jobs Act (the “Act”). The Act, which is also
commonly referred to as “US tax reform”, significantly changes US corporate income tax laws by,
among other things, reducing the US corporate income tax rate to 21% starting in 2018 and creating a
territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of US
subsidiaries. As a result, Schlumberger recorded a net charge of $76 million during the fourth quarter of
2017. This amount, which is included in Tax expense (benefit) in the Consolidated Statement of Income
(Loss), consists of two components: (i) a $410 million charge relating to the one-time mandatory tax on
previously deferred earnings of certain non-US subsidiaries that are owned either wholly or partially by
a US subsidiary of Schlumberger, and (ii) a $334 million credit resulting from the remeasurement of
Schlumberger’s net deferred tax liabilities in the US based on the new lower corporate income tax rate.

48

Although the $76 million net charge represents what Schlumberger believes is a reasonable estimate of
the impact of the income tax effects of the Act on Schlumberger’s Consolidated Financial Statements as
of December 31, 2017, it should be considered provisional. Once Schlumberger finalizes certain tax
positions when it files its 2017 US tax return, it will be able to conclude whether any further adjustments
are required to its net deferred tax liability balance in the US of $1.7 billion as of December 31, 2017, as
well as to the liability associated with the one-time mandatory tax. Any adjustments to these provisional
amounts will be reported as a component of Tax expense (benefit) in the reporting period in which any
such adjustments are determined, which will be no later than the fourth quarter of 2018.

During the second quarter of 2017, Schlumberger entered into a financing agreement with its primary
customer in Venezuela. This agreement resulted in the exchange of $700 million of outstanding
accounts receivable for promissory notes with a three-year term that bear interest at the rate of 6.50%
per annum. Schlumberger recorded these notes at their estimated fair value on the date of the exchange,
which resulted in a charge of $460 million. Schlumberger is accounting for the promissory notes as
available-for-sale securities reported at fair value in Other Assets, with unrealized gains and losses
included as a component of Accumulated other comprehensive loss. Following the $105 million other-
than-temporary impairment charge described above, the new cost basis of these promissory notes is
$135 million, which approximates their fair value at December 31, 2017.

During the second quarter of 2017, Schlumberger entered into discussions with a customer relating to
certain of its outstanding accounts receivable. As a result of these discussions, Schlumberger recorded a
charge of $50 million to adjust these receivables to their estimated net realizable value.

Schlumberger recorded $308 million of charges during 2017 relating to employee benefits, facility
closures and other merger and integration-related costs, primarily in connection with Schlumberger’s
2016 acquisition of Cameron International Corporation (“Cameron”) (See Note 4 – Acquisitions).

Schlumberger reduced its headcount during the second quarter of 2016 as a result of persistent
unfavorable oil and gas industry market conditions and the expected impact on customer activity levels.
Schlumberger recorded a $646 million charge during the second quarter of 2016 associated with this
headcount reduction. During the fourth quarter of 2016, Schlumberger further reduced its headcount in
order to streamline its support cost structure. Schlumberger recorded an additional $234 million charge
during the fourth quarter associated with these actions.

During the fourth quarter of 2016, Schlumberger recorded $302 million of restructuring charges
consisting of the following: $165 million of facility closure costs due to the expected sale of certain
owned properties and the termination of certain facility leases; $98 million of asset write-offs associated
with exiting certain activities; and $39 million of contract termination costs.

During the fourth quarter of 2016, the Central Bank of Egypt took the decision to float its currency and
the Egyptian pound devalued relative to the US dollar. As a result, Schlumberger recorded a $63 million
devaluation charge during the fourth quarter of 2016.

As a result of the unfavorable oil and gas industry market conditions that continued to deteriorate in the
first half of 2016, and the related impact on 2016 first half operating results and expected customer
activity levels, Schlumberger determined that the carrying values of certain assets were no longer
recoverable and also took certain decisions that resulted in the following impairment and other charges
during the second quarter of 2016:

-
-
-
-
-

-

$209 million impairment of pressure pumping equipment in North America.
$165 million impairment of facilities in North America.
$684 million of other fixed asset impairments primarily relating to underutilized equipment.
$616 million write-down of the carrying value of certain inventory to its net realizable value.
$198 million impairment of certain multiclient seismic data, largely related to the US Gulf of
Mexico.
$55 million of other restructuring costs.

The fair value of the impaired fixed assets and multiclient seismic data was estimated based on the
projected present value of future cash flows that these assets are expected to generate. Such estimates
included unobservable inputs that required significant judgments.

In connection with Schlumberger’s acquisition of Cameron, Schlumberger recorded $349 million of
charges, classified as Merger & integration in the Consolidated Statement of Income (Loss), consisting
of the following: $83 million relating to employee benefits for change-in-control arrangements and
retention bonuses; $45 million of transaction costs, including advisory and legal fees; $61 million of
facility closure costs, and $160 million of other merger and integration-related costs. Additionally,
Schlumberger recorded $299 million of charges relating to the amortization of purchase accounting
adjustments associated with the write-up of acquired inventory to its estimated fair value, which is
classified in Cost of sales in the Consolidated Statement of Income (Loss). This amortization was
presented as a component of Merger & integration in the prior year; however, Schlumberger reclassified
this prior period item to Cost of sales in the current year.

Schlumberger reduced its headcount during the first quarter of 2015 as a result of the severe fall in
activity in North America, combined with the impact of lower international activity due to customer
budget cuts driven by lower oil prices. Schlumberger recorded a $390 million charge during the first
quarter associated with this headcount reduction as well as an incentivized leave of absence program.
Based on the activity outlook for 2016, as well as to further streamline its support structure,
Schlumberger decided to further reduce its headcount and expand its incentivized leave of absence
program during the fourth quarter of 2015. Schlumberger recorded an additional $530 million charge
during the fourth quarter associated with these actions.

As a result of unfavorable oil and gas industry market conditions that continued to deteriorate and their
impact on the activity outlook, Schlumberger determined that the carrying values of certain assets were
no longer recoverable and also took certain decisions that resulted in the following impairment and
restructuring charges during the fourth quarter of 2015:

-

-
-

$776 million of fixed asset impairments primarily related to underutilized pressure pumping and
other equipment in North America, as well as certain lower-tier drilling rigs.
$269 million to write-down the carrying value of certain inventory, primarily in North America.
$182 million to reduce the carrying value of an investment in an SPM project to its estimated fair
value, as a result of the decline in commodity prices and considering this project was approaching
the end of its contractual term.

-

$177 million associated with certain of Schlumberger’s owned and leased facilities, including the
expected sale of certain properties and the termination of certain leases.
$77 million relating to assets that were no longer recoverable as a result of geopolitical issues in
certain countries in the Middle East.
$41 million relating to contract termination costs.
$84 million of other charges associated with then current market conditions, including $40 million
relating to an other-than-temporary impairment of marketable securities and $15 million relating to
the impairment of an equity-method investment.

Certain of these impairment charges were estimated based on the projected present value of future cash
flows, which included unobservable inputs that required significant judgments.

In February 2015, the Venezuelan government replaced the SICAD II exchange rate (described in
further detail below) with a new foreign exchange market system known as SIMADI. The SIMADI
exchange rate was approximately 192 Venezuelan Bolivares fuertes to the US dollar as of March 31,
2015. As a result, Schlumberger recorded a $49 million devaluation charge during the first quarter of
2015, reflecting the adoption of the SIMADI exchange rate.

the Consolidated Statement of Income (Loss):

4. Acquisitions

Cameron

On April 1, 2016, Schlumberger acquired all of the outstanding shares of Cameron, a leading provider of flow
equipment products, systems and services to the oil and gas industry worldwide. The acquisition is expected to
create technology-driven growth by integrating Schlumberger reservoir and well technologies with Cameron
wellhead and surface equipment, flow control and processing technology. The combination of the two
complementary technology portfolios provides the industry’s most comprehensive range of products and
services, from exploration to production and integrated pore-to-pipeline solutions that optimize hydrocarbon
recovery to deliver reservoir performance.

Under the terms of the merger agreement, Cameron became a wholly-owned subsidiary of Schlumberger. Each
share of Cameron common stock issued and outstanding immediately prior to the effective time of the merger
was converted into the right to receive 0.716 shares of Schlumberger stock and $14.44 in cash.

Schlumberger recorded an adjustment of $299 million to write-up the acquired inventory to its estimated
fair value. Schlumberger’s 2016 Cost of sales reflected this increased valuation.
In connection with the merger, Schlumberger assumed all of the debt obligations of Cameron, including its
$2.75 billion of fixed rate notes. Schlumberger recorded a $244 million adjustment to increase the carrying
amount of these notes to their estimated fair value. This adjustment is being amortized as a reduction of
interest expense over the remaining term of the respective obligations.
In connection with the acquisition accounting, Schlumberger provided deferred taxes related to, among
other items, the estimated fair value adjustments for acquired inventory, intangible assets and assumed debt
obligations.
Prior to the completion of the merger, Cameron and Schlumberger operated OneSubsea, a joint venture that
manufactured and developed products, systems and services for the subsea oil and gas market, which was
40% owned by Schlumberger and 60% owned by Cameron. OneSubsea is now owned 100% by
Schlumberger. As a result of obtaining control of this joint venture, Schlumberger was required to
remeasure its previously held equity interest
in the joint venture to its acquisition-date fair value.
Schlumberger determined that the estimated fair value of its previously held equity interest approximated its
carrying value. Accordingly, Schlumberger did not recognize any gain or loss on this transaction.
The goodwill recognized is primarily attributable to expected synergies that will result from combining the
operations of Schlumberger and Cameron, as well as intangible assets which do not qualify for separate
recognition. The amount of goodwill that is deductible for income tax purposes is not significant.

Supplemental Pro Forma Financial Information

Cameron’s results of operations have been included in Schlumberger’s financial statements for periods
subsequent to the closing of the acquisition on April 1, 2016. Businesses acquired from Cameron contributed
revenues of approximately $4 billion and pretax operating income of approximately $0.7 billion for the period
from April 1, 2016 through December 31, 2016.

The following supplemental pro forma results of operations assume that Cameron had been acquired on
January 1, 2015. The supplemental pro forma financial information was prepared based on the historical financial
information of Schlumberger and Cameron and has been adjusted to give effect to pro forma adjustments that are
both directly attributable to the transaction and factually supportable. The pro forma amounts reflect certain
adjustments to amortization expense, interest expense and income taxes resulting from purchase accounting. The
pro forma results for the year ended December 31, 2016 reflect adjustments to exclude after-tax merger and
integration costs of $285 million and after-tax charges relating to the amortization of the inventory fair value
adjustment of $209 million. As required by generally accepted accounting principles, the pro forma results for
the year ended December 31, 2015 have been adjusted to include after-tax adjustments for merger and integration
costs of $285 million and the after-tax charges relating to the amortization of the inventory fair value adjustment
of $209 million.

The supplemental pro forma financial information presented below is unaudited and does not include any
anticipated cost savings or the expected realization of other synergies associated with this transaction.
Accordingly, this supplemental pro forma financial information is presented for informational purposes only and
is not necessarily indicative of what the actual results of operations of the combined company would have been
had the acquisition occurred on January 1, 2015, nor is it indicative of future results of operations.

(1) Schlumberger maintains a €5.0 billion Guaranteed Euro Medium Term Note program that provides for the issuance of various
types of debt instruments such as fixed or floating rate notes in euro, US dollar or other currencies. Schlumberger issued
€0.5 billion 1.50% Guaranteed Notes due 2019 under this program in 2013.

(2) Represents long-term fixed rate debt obligations assumed in connection with the acquisition of Cameron, net of amounts

repurchased subsequent to the closing of the transaction.

Schlumberger Limited fully and unconditionally guarantees the securities issued by certain of its subsidiaries,
including securities issued by Schlumberger Investment SA, a wholly-owned finance subsidiary of Schlumberger.

At December 31, 2017, Schlumberger had separate committed credit facility agreements aggregating $6.6 billion with
commercial banks, of which $3.6 billion was available and unused. This included $6.3 billion of committed facilities
which support commercial paper programs in the United States and Europe, of which $1.0 billion matures in February
2018, $1.8 billion matures in July 2018, $1.5 billion matures in November 2020, and $2.0 billion matures in February
2021. Interest rates and other terms of borrowing under these lines of credit vary from country to country.

Commercial paper borrowings are classified as long-term debt to the extent they are backed up by available and unused
committed credit facilities maturing in more than one year and to the extent it is Schlumberger’s intent to maintain

58

these obligations for longer than one year. Borrowings under the commercial paper program at December 31,
2017 were $3.0 billion, of which $1.7 billion was classified within Long-term debt and $1.3 billion was classified
in Short-term borrowings and current portion of
in the Consolidated Balance Sheet. At
December 31, 2016, borrowings under the commercial paper program were $2.6 billion, of which $2.4 billion
was classified within Long-term debt and $0.2 billion was classified in Short-term borrowings and current
portion of long-term debt in the Consolidated Balance Sheet.

long-term debt

The weighted average interest rate on variable rate debt as of December 31, 2017 was 2.3%.

Long-term Debt as of December 31, 2017 is due as follows: $1.5 billion in 2019, $2.8 billion in 2020,
$4.3 billion in 2021, $2.6 billion in 2022, $1.6 billion in 2023, $1.7 billion in 2025 and $0.4 billion thereafter.

The fair value of Schlumberger’s Long-term Debt at December 31, 2017 and December 31, 2016 was
$15.2 billion and $16.8 billion, respectively, and was estimated based on quoted market prices.

11. Derivative Instruments and Hedging Activities

Schlumberger is exposed to market risks related to fluctuations in interest rates and foreign currency exchange
rates. To mitigate these risks, Schlumberger utilizes derivative instruments. Schlumberger does not enter into
derivative transactions for speculative purposes.

Interest Rate Risk

Schlumberger is subject to interest rate risk on its debt and its investment portfolio. Schlumberger maintains an
interest rate risk management strategy that uses a mix of variable and fixed rate debt combined with its
investment portfolio, and occasionally interest rate swaps, to mitigate the exposure to changes in interest rates.

During 2013, Schlumberger entered into a cross-currency swap for a notional amount of €0.5 billion in order to
hedge changes in the fair value of Schlumberger’s €0.5 billion 1.50% Guaranteed Notes due 2019. Under the
terms of this swap, Schlumberger will receive interest at a fixed rate of 1.50% on the euro notional amount and
pay interest at a floating rate of three-month LIBOR plus approximately 64 basis points on the US dollar notional
amount.

During 2017, a Canadian dollar functional currency subsidiary of Schlumberger issued $1.1 billion of US dollar
denominated debt. Schlumberger entered into cross-currency swaps for an aggregate notional amount of
$1.1 billion in order to hedge changes in the fair value of its $0.5 billion 2.20% Senior Notes due 2020 and its
$0.6 billion 2.65% Senior Notes due 2022. These cross-currency swaps effectively convert the US dollar notes to
Canadian dollar denominated debt with fixed annual interest rates of 1.97% and 2.52%, respectively.

These cross-currency swaps are designated as a fair value hedges of the underlying debt. These derivative
instruments are marked to market with gains and losses recognized currently in income to largely offset the
respective gains and losses recognized on changes in the fair value of the hedged debt.

At December 31, 2017, Schlumberger had fixed rate debt aggregating $13.6 billion and variable rate debt
aggregating $4.6 billion, after taking into account the effect of interest rate swaps.

Short-term investments were $3.3 billion at December 31, 2017. The carrying value of these investments
approximated fair value.

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts its business in over 85 countries. Schlumberger’s functional
currency is primarily the US dollar. Approximately 78% of Schlumberger’s revenues in 2017 was denominated

59

in US dollars. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign
currencies. Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in
which Schlumberger conducts business, the US dollar–reported expenses will increase (decrease).

Schlumberger is exposed to risks on future cash flows to the extent that the local currency is not the functional currency and
expenses denominated in local currency are not equal to revenues denominated in local currency. Schlumberger is also
exposed to risks on future cash flows relating to certain of its fixed rate debt denominated in currencies other than the
functional currency. Schlumberger uses foreign currency forward contracts to provide a hedge against a portion of these cash
flow risks. These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of
the hedge recorded on the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss. Amounts recorded in
Accumulated Other Comprehensive Loss are reclassified into earnings in the same period or periods that the hedged item is
recognized in earnings. The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded
directly to earnings.

At December 31, 2017, Schlumberger recognized a cumulative net $3 million gain in Accumulated other comprehensive loss
relating to revaluation of foreign currency forward contracts designated as cash flow hedges, the majority of which is
expected to be reclassified into earnings within the next 12 months.

Schlumberger is exposed to changes in the fair value of assets and liabilities denominated in currencies other than the
functional currency. While Schlumberger uses foreign currency forward contracts to economically hedge this exposure as it
relates to certain currencies, these contracts are not designated as hedges for accounting purposes. Instead, the fair value of
the contracts is recorded on the Consolidated Balance Sheet and changes in the fair value are recognized in the Consolidated
Statement of Income, as are changes in the fair value of the hedged item. Transaction losses of $57 million, $93 million and
$76 million, net of related hedging activities, were recognized in the Consolidated Statement of Income (Loss) in 2017, 2016
and 2015, respectively. Included in these amounts are $63 million of losses relating to Egypt in 2016 and $49 million of
losses relating to Venezuela in 2015. See Note 3–Charges and Credits for further details.

At December 31, 2017, contracts were outstanding for the US dollar equivalent of $5.0 billion in various foreign currencies,
of which $1.8 billion relates to hedges of debt denominated in currencies other than the functional currency.

The fair value of outstanding derivatives was not material at December 31, 2017 and 2016.

The effect of derivative instruments designated as fair value hedges and those not designated as hedges on the Consolidated
Statement of Income (Loss) was as follows:

13. Stock-based Compensation Plans

Schlumberger has three types of stock-based compensation programs: (i) stock options, (ii) a restricted stock, restricted
stock unit and performance share unit program (collectively referred to as “restricted stock”) and (iii) a discounted
stock purchase plan (DSPP).

Stock Options

Key employees are granted stock options under Schlumberger stock option plans. For all stock options granted,
the exercise price equals the average of the high and low sales prices of Schlumberger stock on the date of grant;
the maximum term is ten years, and the options generally vest in increments over five years.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-
pricing model with the following weighted-average assumptions and resulting weighted-average fair value per
share:

Restricted Stock

Schlumberger grants performance share units to certain executives. The number of shares earned is determined at
the end of each performance period, which is generally three years, based on Schlumberger’s achievement of
certain predefined targets as defined in the underlying performance share unit agreement. In the event
Schlumberger exceeds the predefined target, shares for up to the maximum of 250% of the target award may be
awarded. In the event Schlumberger falls below the predefined target, a reduced number of shares may be
granted. If Schlumberger falls below the threshold award performance level, no shares will be awarded. As of
December 31, 2017, 1.1 million performance share units were outstanding based assuming the achievement of
100% of target.

All other restricted stock awards generally vest at the end of three years.

Restricted stock awards generally do not pay dividends or have voting rights prior to vesting. Accordingly, the
fair value of a restricted stock award is the quoted market price of Schlumberger’s stock on the date of grant less
the present value of the expected dividends not received prior to vesting.

Discounted Stock Purchase Plan

Under the terms of the DSPP, employees can choose to have a portion of their earnings withheld, subject to
certain restrictions, to purchase Schlumberger common stock. The purchase price of the stock is 92.5% of the
lower of the stock price at the beginning or end of the plan period at six-month intervals.

The fair value of the employees’ purchase rights under the DSPP was estimated using the Black-Scholes model
with the following assumptions and resulting weighted-average fair value per share:

The above deferred tax balances at December 31, 2017 and 2016 were net of valuation allowances relating to net
operating losses in certain countries of $119 million and $97 million, respectively.

As a direct result of Schlumberger’s 2016 acquisition of Cameron, certain non-US subsidiaries of Cameron are
either wholly or partially owned by a US subsidiary of Schlumberger. As described in Note 3, Schlumberger
recorded a $410 million charge relating to the one-time mandatory tax on previously deferred foreign earnings of
Schlumberger’s US subsidiary. After considering the impact of foreign tax credits and tax losses, the resulting
cash tax payable as a result of the one-time mandatory tax on previously deferred foreign earnings of
Schlumberger’s US subsidiary will not be significant.

Other than as described above, Schlumberger generally does not provide for taxes related to its undistributed
earnings because such earnings either would not be taxable when remitted or they are considered to be
indefinitely reinvested. Taxes that would be incurred if the undistributed earnings of other Schlumberger
subsidiaries were distributed to their ultimate parent company would not be material.

A number of the jurisdictions in which Schlumberger operates have tax laws that are not fully defined and are
evolving. Schlumberger’s tax filings are subject to regular audit by the tax authorities. These audits may result in
assessments for additional taxes that are resolved with the tax authorities, or potentially through the courts. Tax
liabilities are recorded based on estimates of additional taxes that will be due upon the conclusion of these audits.
Due to the uncertain and complex application of tax regulations, the ultimate resolution of audits may result in
liabilities which could be materially different from these estimates.

The amounts above exclude accrued interest and penalties of $195 million, $178 million and $176 million at December 31,
2017, 2016 and 2015, respectively. Schlumberger classifies interest and penalties relating to uncertain tax positions within
Tax expense (benefit) in the Consolidated Statement of Income (Loss).

The following table summarizes the tax years that are either currently under audit or remain open and subject to examination
by the tax authorities in the most significant jurisdictions in which Schlumberger operates:

In certain of the jurisdictions noted above, Schlumberger operates through more than one legal entity, each of which may
have different open years subject to examination. The table above presents the open years subject to examination for the most
material of the legal entities in each jurisdiction. Additionally, it is important to note that tax years are technically not closed
until the statute of limitations in each jurisdiction expires. In the jurisdictions noted above, the statute of limitations can
extend beyond the open years subject to examination.

16. Contingencies

Schlumberger and its subsidiaries are party to various legal proceedings from time to time. A liability is accrued
when a loss is both probable and can be reasonably estimated. Management believes that the probability of a
material loss with respect to any currently pending legal proceeding is remote. However, litigation is inherently
uncertain and it is not possible to predict the ultimate disposition of any of these proceedings.

17. Segment Information

Schlumberger’s segments are as follows:

(cid:129)

(cid:129)

18. Pension and Other Benefit Plans

Pension Plans

Schlumberger sponsors several defined benefit pension plans that cover substantially all US employees hired
prior to October 1, 2004. The benefits are based on years of service and compensation, on a career-average pay
basis.

In addition to the US defined benefit pension plans, Schlumberger sponsors several other international defined
benefit pension plans. The most significant of these international plans are the International Staff Pension Plan
and the UK pension plan (collectively, the “International plans”). The International Staff Pension Plan covers
certain international employees hired prior to July 1, 2014 and is based on years of service and compensation on
a career-average pay basis. The UK plan covers employees hired prior to April 1, 1999, and is based on years of
service and compensation, on a final salary basis.

The weighted-average assumed discount rate, compensation increases and expected long-term rate of return on
plan assets used to determine the net pension cost for the US and International plans were as follows:

The unfunded liability represents the difference between the plan assets and the projected benefit obligation (PBO).
The PBO represents the actuarial present value of benefits based on employee service and compensation and includes
an assumption about future compensation levels. The accumulated benefit obligation represents the actuarial present
value of benefits based on employee service and compensation, but does not include an assumption about future
compensation levels.

Asset performance is monitored frequently with an overall expectation that plan assets will meet or exceed the
weighted index of its target asset allocation and component benchmark over rolling five-year periods.

The expected rate of return on assets assumptions reflect the long-term average rate of earnings expected on
funds invested or to be invested. The assumptions have been determined based on expectations regarding future
rates of return for the portfolio considering the asset allocation and related historical rates of return. The
appropriateness of the assumptions is reviewed annually.

The fair value of Schlumberger’s pension plan assets at December 31, 2017 and 2016, by asset category, is
presented below and was determined based on valuation techniques categorized as follows:

(cid:129)

Level One: The use of quoted prices in active markets for identical instruments.

Level Two: The use of quoted prices for similar instruments in active markets or quoted prices for
identical or similar instruments in markets that are not active or other inputs that are observable in
the market or can be corroborated by observable market data.

Level Three: The use of significant unobservable inputs that
management’s estimates of assumptions that market participants would use in pricing.

US equities include companies that are well-diversified by industry sector and equity style (i.e., growth and value
strategies). Active and passive management strategies are employed. Investments are primarily in large capitalization
stocks and, to a lesser extent, mid- and small-cap stocks.

International equities are invested in companies that are traded on exchanges outside the US and are well-diversified by
industry sector, country and equity style. Active and passive strategies are employed. The vast majority of the
investments are made in companies in developed markets, with a small percentage in emerging markets.

Corporate bonds consist primarily of investment grade bonds from diversified industries.

Government and government-related debt securities are comprised primarily of inflation-protected US treasuries and,
to a lesser extent, other government-related securities.

Collateralized mortgage obligations and mortgage backed-securities are debt obligations that represent claims to the
cash flows from pools of mortgage loans, which are purchased from banks, mortgage companies, and other originators
and then assembled into pools by governmental, quasi-governmental and private entities.

Private equity includes investments in several funds of funds.

Real estate primarily includes investments in real estate limited partnerships, concentrated in commercial real estate.

Schlumberger’s funding policy is to annually contribute amounts that are based upon a number of factors
including the actuarial accrued liability, amounts that are deductible for income tax purposes, legal funding
requirements and available cash flow. Schlumberger expects to contribute approximately $125 million to its
postretirement benefit plans in 2018, subject to market and business conditions.

Postretirement Benefits Other Than Pensions

Schlumberger provides certain healthcare benefits to certain former US employees who have retired. Effective
April 1, 2015, Schlumberger changed the way it provides healthcare coverage to certain retirees who are age 65
and over. Under the amended plan, these retirees transferred to individual coverage under the Medicare
Exchange. Schlumberger subsidizes the cost of the program by providing these retirees with a Health
Reimbursement Account. The annual subsidy may be increased based on medical cost inflation, but it will not be
increased by more than 5% in any given year.

The actuarial assumptions used to determine the accumulated postretirement benefit obligation and net periodic
benefit cost for the US postretirement medical plan were as follows:

Discount rate . . . . . . . . . . . . . . . . . . . . . . . . .
Return on plan assets . . . . . . . . . . . . . . . . . . .
Current medical cost trend rate . . . . . . . . . . .

The unfunded liability is included in Postretirement Benefits in the Consolidated Balance Sheet.

The assets of the US postretirement medical plan are invested 59% in equity securities and 41% in debt securities
at December 31, 2017. The fair value of these assets was primarily determined based on Level Two valuation
techniques.

Management’s Report on Internal Control Over Financial Reporting

Schlumberger management
is responsible for establishing and maintaining adequate internal control over
financial reporting as defined in Rule 13a–15(f) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”). Schlumberger’s internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted accounting principles.

Because of its inherent
internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

limitations,

Schlumberger management assessed the effectiveness of its internal control over financial reporting as of
December 31, 2017. In making this assessment, it used the criteria set forth in 2013 by the Committee of
Sponsoring Organizations of the Treadway Commission in Internal Control–Integrated Framework. Based on
this assessment Schlumberger’s management has concluded that, as of December 31, 2017, its internal control
over financial reporting is effective based on those criteria.

The effectiveness of Schlumberger’s internal control over financial reporting as of December 31, 2017 has been
audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their
report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders
of Schlumberger Limited

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Schlumberger Limited and its subsidiaries
(the “Company”) as of December 31, 2017 and 2016, and the related consolidated statements of income (loss),
comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the period ended
including the related notes (collectively referred to as the “consolidated financial
December 31, 2017,
statements”). We also have audited the Company’s internal control over financial reporting as of December 31,
2017, based on criteria established in Internal Control–Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (“COSO”).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the
financial position of the Company as of December 31, 2017 and 2016 and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 2017 in conformity with accounting
principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in
all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria
established in Internal Control–Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective
internal control over financial reporting, and for its assessment of the effectiveness of internal control over
financial reporting, included in the accompanying Management’s Report on Internal Control over Financial
Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on
the Company’s internal control over financial reporting based on our audits. We are a public accounting firm
registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to
be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are
free of material misstatement, whether due to error or fraud, and whether effective internal control over financial
reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material
misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures
that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of
the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our
audits also included performing such other procedures as we considered necessary in the circumstances. We
believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in

81

accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company’s assets that could have a material effect on the financial statements.

internal control over financial reporting may not prevent or detect
Because of its inherent
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Schlumberger has carried out an evaluation under the supervision and with the participation of Schlumberger’s
management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the
effectiveness of Schlumberger’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e)
and 15d-15(e) under the Exchange Act as of the end of the period covered by this report. Based on this
evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this report,
Schlumberger’s disclosure controls and procedures were effective to provide reasonable assurance that

83

information required to be disclosed in the reports that Schlumberger files or submits under the Exchange Act is
recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange
Commission’s rules and forms. Schlumberger’s disclosure controls and procedures include controls and
procedures designed so that information required to be disclosed in reports filed or submitted under the Exchange
Act is accumulated and communicated to its management, including the CEO and the CFO, as appropriate, to
allow timely decisions regarding required disclosure. There has been no change in Schlumberger’s internal
control over financial reporting that occurred during the fourth quarter of 2017 that has materially affected, or is
reasonably likely to materially affect, Schlumberger’s internal control over financial reporting.

Item 9B. Other Information.

In 2013, Schlumberger completed the wind down of its service operations in Iran. Prior to this, certain non-US
subsidiaries provided oilfield services to the National Iranian Oil Company and certain of its affiliates (“NIOC”).

Schlumberger’s residual transactions or dealings with the government of Iran during 2017 consisted of payments
of taxes and other typical governmental charges. Certain non-US subsidiaries of Schlumberger maintain
depository accounts at the Dubai branch of Bank Saderat Iran (“Saderat”), and at Bank Tejarat (“Tejarat”) in
Tehran and in Kish for the deposit by NIOC of amounts owed to non-US subsidiaries of Schlumberger for prior
services rendered in Iran and for the maintenance of such amounts previously received. One non-US subsidiary
also maintained an account at Tejarat for payment of local expenses such as taxes. Schlumberger anticipates that
it will discontinue dealings with Saderat and Tejarat following the receipt of all amounts owed to Schlumberger
for prior services rendered in Iran.

During the fourth quarter of 2016, a non-US subsidiary entered into a memorandum of understanding (“MOU”)
with NIOC relating to the non-disclosure of data required for the technical evaluation of an oilfield project. In the
first quarter of 2017, the Schlumberger subsidiary provided NIOC with written notice that it was terminating the
MOU, effective March 11, 2017. The MOU did not involve the provision of services. During the second quarter
of 2017, and in furtherance of the termination of the MOU, the Schlumberger subsidiary had residual dealings
with the NIOC consisting solely of the return of client data.
