Letter to Shareholders

The gradual recovery of the oil price during the first 
three quarters of 2018 drove strong global activity, 
particularly  in  the  development  of  unconventional 
land  resources  in  the  US.  Once  oil  prices  began 
to  fall  sharply  in  the  fourth  quarter,  however,  US 
land  activity  slowed  while  international  activity 
remained  firm  as  E&P  investment  continued  to 
be  robust.  Against  this  backdrop,  Schlumberger 
revenue  increased  8%  year-on-year  to  reach  
$32.8  billion  with  international  revenue  growth 
outpacing that of North America in the third quarter. 
Earnings grew for the second consecutive year.

Paal Kibsgaard 
Chairman and Chief Executive Officer

In the oil markets, sentiment was stable and positive for the first three quarters of 2018, supporting the rising oil price 
environment.  OECD  crude  and  product  stocks  continued  a  downward  trend  that  began  in  the  third  quarter  of  2016. 
Production cuts from OPEC and Russia in 2017 strengthened the oil price. Activity picked up globally and, as oil reached 
its peak price for the year in October, production from major producers, including unconventional US production, began 
to surprise to the upside. Output in Libya rebounded sharply; Saudi Arabia and the United Arab Emirates each recorded 
record production output; and dispensations from the Iran export sanctions all contributed to increased production that 
more than offset declines elsewhere.

As a result, the market became oversupplied at the beginning of the fourth quarter despite the anticipated slowdown in 
production growth in the Permian Basin due to capacity takeaway constraints. This, coupled with concerns about global oil 
demand, caused oil prices to plummet by more than 40% during the fourth quarter of 2018 and led to a sudden and sharp 
decrease in US land well completions activity during the final months of the year.

In North America, our financial results were driven by the strength of activity in the development of shale oil resources that 
increased US production to record levels. In line with this, our OneStim® business grew by 41% year-over-year, boosted by 
the performance of our technology and the benefit of our transformation program, which has streamlined our operations. 
In drilling services, the market leadership of our rotary steerable systems and the increasing deployment of our innovative 
range of drill bits drove growth throughout the year. Offshore activity across North America, however, remained subdued 
although customer activity showed early signs of growth toward the end of the year.

International revenue grew faster than in North America 
during  the  third  quarter  of  2018  for  the  first  time  since 
2014,  marking  the  beginning  of  a  positive  activity  trend 
after  three  consecutive  years  of  declining  revenue.  This 
was  driven  by  the  increased  activity  of  the  national  oil 
companies  as  they  began  to  accelerate  investment  in 
longer-term resource development. One major result of this 
for Schlumberger during the year was the strong demand 
for our integrated drilling services, where we deployed an 
additional 80 rigs on major projects in Saudi Arabia, India, 
Norway, Russia, and Iraq. These integrated drilling projects 
represent significant growth and performance upside for 
our operations in the coming years.

Our  performance  during  the  year  benefitted  from  new 
technology sales that remained steady at 23% of total sales. 
During  the  year,  we  commercialized  new  technologies 
such  as  the  HyperBlade*  hyperbolic  diamond  element 
bit,  GyroSphere*  MEMS  gyro-while-drilling  service, 
Fulcrum* cement-conveyed frac performance technology, 
and  Concert*  well  testing  live  performance.  This  strong 
commitment to technology innovation is based on our firm 
belief that technology drives E&P performance by improving 
operational efficiency and lowering the cost per barrel.

Although our health and safety performance in the fourth 
quarter was our safest on record regarding recordable injuries,  
our full-year performance deteriorated compared with the 
previous year. Regretfully, we suffered three driving-related 
fatalities in North America involving two contractors and 
one  employee,  and  a  contractor  was  fatally  injured  in  a 
rigsite  incident.  In  our  continual  pursuit  of  workplace 
safety, our focus for 2019 will leverage the Schlumberger 
SAFE program, in which everyone in the company makes 
a personal commitment to themselves, their families, and 
their colleagues to ensure their own safety and the safety of 
others. This program has multiple initiatives, including the 
use of new mobile technologies to increase driving safety.

“ Taken together, our people, 
technology, and processes make 
us the partner of choice in the 
sustainable, responsible development 
of hydrocarbon resources.”

Other Revenue

During  the  past  four  years,  we  have  modernized  our 
operating platform, creating stronger and more specialized 
operations support functions. Now that our transformation 
is largely complete, the improvements we have made enhance the development and delivery of our technology along with the 
reliability of our products and services. Strengthened by our increased focus on teamwork and functional accountability, these 
combined improvements have resulted in more robust execution capabilities and increased performance.

One of our greatest strengths is the diversity of our people, with men and women of many nationalities, cultures, and technical 
backgrounds working together and sharing common objectives. We attract and retain top performers worldwide by addressing 
the evolving needs of our workforce in terms of competency development and quality of life. Our domain experts provide a 
competitive advantage, enabling us to design and execute efficient operations that maximize hydrocarbon recovery while our 
technology and processes are helping to reduce the environmental footprint of E&P operations. We work closely with our 
customers to achieve environmental, social, and governance (ESG) objectives; mitigate social and environmental risks; and 

3

lower greenhouse gas emissions in field operations. 
This  is  integral  to  achieving  our  goal  to  improve 
social and economic conditions in the communities 
where we live and work. Taken together, our people, 
technology,  and  processes  make  us  the  partner  of 
choice in the sustainable, responsible development 
of hydrocarbon resources.

Looking  forward,  we  see  a  series  of  factors  that  
will likely define the oil market in the coming year.
These  include  the  impact  of  the  latest  OPEC  and 
Russia  production  cuts,  slowing  production  growth 
from North America land driven by lower investments 
and activity toward the end of 2018, the expiration of 
the dispensations given to the Iran export sanctions, 
and the efforts being made to resolve the global trade 
discussions. Based on these factors, we expect the oil 
market sentiments to improve over the course of 2019, 
leading to a corresponding recovery in oil prices.

In  a  market  environment  with  continued  robust 
economic growth, a multiyear increase in international 
E&P investment will be required. Through the success 
we  have  achieved  in  modernizing  our  operating 
platform,  expanding  our  technology  offering,  and 
evolving  our  business  models,  we  are  very  well 
positioned  to  outgrow  the  market  in  the  coming 
upcycle,  generate  superior  operating  margins,  and 
deliver cash returns that benefit our shareholders.

On  behalf  of  the  entire  Schlumberger  organization 
around the world, I would like to thank our customers 
and our shareholders for their continued confidence 
and support. I would also like to personally thank each 
Schlumberger employee for their strong commitment 
and steadfast dedication to the company. The future 
remains bright for Schlumberger.

Performed by Schlumberger

This  was  the  19th  year  of  the  Performed  by  Schlumberger 
program, which recognizes projects and their team members who 
have demonstrated exceptional levels of teamwork, innovation, 
and business impact for Schlumberger. Only one project receives 
the Chairman’s Award, representing an outstanding example of 
our core values: our people, our commitment to technology, and 
our determination to produce superior profits. 

In  2018,  405  projects  competed  in  the  Performed  by 
Schlumberger  program.  Schlumberger  people  around  the 
globe cast their votes for the top three submissions, thereby 
shortening  the  list  of  contenders  to  seven  projects.  Several 
among these seven were recognized as winners of a Silver or 
Gold Performed by Schlumberger award, but only one received 
the highest accolade—the Chairman’s Award. 

This  year’s  winner  was  the  Wireline  product  line  with  The  
Rise of Remote project. Wireline is at the forefront of digital  
enablement  in  the  E&P  industry  by  combining  downhole 
technologies  with  a  highly  effective  and  robust  surface 
organizational  integration  between  wellsites  and  remote 
operations centers where domain experts provide borderless 
competency for customers on a 24/7 basis. 

Wireline  remote  operations  have  reduced  the  wellsite  
footprint;  health,  safety,  and  environment  (HSE)  exposure; 
and  operational  costs.  These  advances  translate  to  setting 
new  benchmarks  for  operational  efficiency  and  decreased 
nonproductive  time.  Remote  operations  mean  that  informed 
decisions  can  be  made  in  real  time  with  a  higher  level  of 
collaboration between customers and Schlumberger domain 
experts, such as drilling and reservoir engineers.

The Rise of Remote project team received the Performed by 
Schlumberger Award from Chairman and CEO Paal Kibsgaard  
(second from left) and EVP Corporate Engagement Jean-François 
Poupeau (far left). Also pictured, from the left, Maria Lorente, Djamel 
Idri, Sebastien Roche, Nicholas Pantin, Swaty Gupta, and Jessica Latka.

Wireline  remote  operations  embrace  a  collaborative  mindset, 
end-to-end systems knowledge, and redesigned workflows that 
firmly establish and support a new way of working based on 
innovative technology and domain expertise. This begins with 
a critical assessment of how the data are used across reservoir 
characterization, well construction, and field production. During 
the  development  process  as  it  is  conventionally  practiced 
today, many types of data exist in silos, making holistic analysis 
challenging.  Without  a  complete  systems  approach,  precious 
information and time are lost because the lack of interface among 
different systems makes it difficult to share localized knowledge.

The  Wireline  product  line  has  13  remote  operations  centers 
around the globe that benefit from our domain experts, most 
of whom have more than 25 years of field experience. Since 
January 2017, these centers have completed more than 30,000 
hours of logging on more than 3,650 projects worldwide. More 
importantly,  the  remote  operations  model  has  decreased 
nonproductive time by 50% compared with conventional wireline 
models.  This  includes  the  ability  of  the  remote  operations 
engineers to provide their problem-solving expertise on five times 
as many operations without physically traveling to each location.

The Rise of Remote project is being adopted across Schlumberger  
and by our customers to capitalize on the value unlocked by 
digital enablement in the E&P industry.

Technology Drives E&P Performance

New technology has enabled the E&P industry to 
address technical challenges within a variety of 
operating and business environments that are in  
a constant state of change. This has driven 
performance and pushed the technical envelope 
while delivering a superior return on investment to 
the E&P industry. Schlumberger has established an 
extensive portfolio of pore to pipeline technologies 
and services that addresses evolving customer 
needs by increasing efficiency, improving well 
productivity, and lowering the cost per barrel while 
helping to reduce environmental impacts. In the 
past few years, we have enhanced our portfolio  
by adding new levels of technology integration  
and digital-technology enablement in our oilfield 
services operations.

Whether we develop discrete technologies or fully 
integrated systems, Schlumberger expects its 
technologies and services to do more, in the same 
way that consumer digital technologies, such as 
mobile phones, have dramatically altered the way 
we live our daily lives. Although our portfolio 
addresses evolving customer needs by increasing 
efficiency and improving well productivity while 
helping to reduce environmental impacts, 
harnessing more from our technologies is 
increasingly important as market dynamics  
change more rapidly. 

A more agile approach—building further on 
integration and digital enablement in our oilfield 
services operations—is required to continue to 
deliver full-cycle returns. Schlumberger seeks to 
exceed its customers’ needs by deploying 
innovative, digitally enabled technology combined 
with a new way of working and flexible business 
models that together drive company performance.

The Path to Digital Technology Integration

The current oil price environment has driven many oil and gas 
operators to focus on maximizing cash flow by producing their 
fields harder and prioritizing short-term actions versus longer-
term reservoir management. Given this scenario, how can the 
industry  achieve  a  step  change  in  E&P  performance  over 
the full cycle for the benefit of all stakeholders?

One  answer  is  by  adopting  new  technologies  that,  from 
the  start,  have  been  engineered  to  leverage  the  latest 
advances  in  collaborative  and  digital  enablement.  When 
these digitally enabled technologies are combined with our 
domain  expertise,  streamlined  processes,  and  integrated 
systems,  it  makes  us  a  strong  partner  in  the  sustainable 
development of hydrocarbon resources.  

To  capitalize  on  the  latest  advances  in  digital  enablement, 
Schlumberger  has  established  three  technology  centers  that 
innovate within the rapidly evolving world of digital technology, 
automation, and artificial intelligence. Established in 2014, our 
California-based  center  in  Menlo  Park  focuses  on  developing 
software  that  makes  it  possible  to  apply  new  technology  to 
oilfield challenges. Since 2016, our industrial internet center in 

Sugar Land, Texas, has focused on architecture and infrastructure 
development for the cloud, big data, industrial internet of things 
(lIoT), automation, and cybersecurity across multiple platforms. 
In 2017, the Schlumberger-Doll Research Center in Cambridge, 
Massachusetts—which  was  established  in  1948—added  a 
robotics department to support system automation, including 
flexible manufacturing of field equipment, such as drilling rigs.

Together, these centers are helping to create seamless digital 
workflows  for  E&P  domains  by  tapping  into  our  reservoir 
expertise and leadership in hardware and software development. 
This unique combination is enabling Schlumberger to construct 
a  digital  ecosystem  for  today’s  industry  needs  that  can  also 
incorporate  the  next  generations  of  hardware  and  software 
solutions for the technical challenges that lie ahead.

Recent advances in hardware and software solutions include 
HyperBlade  hyperbolic  diamond  element  bit,  GyroSphere 
MEMS gyro-while-drilling service, Fulcrum cement-conveyed 
frac  performance  technology,  and  Concert  well  testing 
live  performance.  Each  of  these  technologies  helps  E&P 
company  performance  by  either  increasing  operational 
efficiency or improving well productivity and, in each case, also 
decreasing the environmental impacts of oilfield operations.

Technology Innovation Center in Menlo Park, California, uses a virtual reality 
headset to view the digital twin of an actual wellsite (left and right sides

Technology Spotlight: GyroSphere Service

Oilfield drilling technology is subject to environmental conditions such as severe mechanical shocks and vibrations. A technician uses a field 
emission scanning electron microscope to analyze a microelectromechanical system (MEMS) sensor for gyro surveying while drilling in the oil field. 
Solid-state technology enables the GyroSphere MEMS sensor to withstand downhole shock and vibration during drilling beyond the limits of 
current gyro technologies.

Gyro surveying is an essential part of drilling because it delivers 
accurate  direction  and  inclination  data  when  regular 
measurements-while-drilling (MWD) tools cannot achieve that 
goal. However, most conventional gyro-while-drilling systems 
continue to depend on mechanical gyroscopes that adversely 
affect the efficiency of drilling operations by requiring a wait 
for running surveys after connections. They are also susceptible 
to the ordinary shock and vibration of drilling activities, which 
means they must be recalibrated after every single run—taking 
up further valuable rig time. 

In  2018,  Schlumberger  introduced  the  GyroSphere  MEMS  
gyro-while-drilling  service  to  improve  drilling  operational 
efficiency. The GyroSphere service uses microelectromechanical 
systems  (MEMS),  which  is  the  same  solid-state  technology 
used within a cell phone GPS unit to pinpoint location.

Gyro-surveying-while-drilling  measurements  using  the 
GyroSphere  service  are  taken  during  drillpipe  connections  
and  the  data  is  available  right  after  drilling  mud  begins 
circulating  in  the  well,  instead  of  30  minutes  later,  as  is  
the  case  with  mechanical  gyros.  Two  surveys  can  now  be 
completed in the same time it takes conventional gyros to start 
one  survey.  This  represents  a  significant  time  savings  for 
operators  routinely  using  gyro-while-drilling  surveys  to  drill 
upper sections of wells in congested areas.

The MEMS gyro-while-drilling surveys sustain the accuracy 
needed  for  today’s  complex  drilling  environment.  
When  combined  with  MWD  surveys,  gyro  surveys  can 
reduce  measurement  uncertainty  by  up  to  45%,  which  
is  beneficial  in  long  horizontal  well  sections  or  when  
drilling smaller targets.

Unlike  other  gyro-surveying-while-drilling  services  in  the  oil 
field today, the GyroSphere service more transparently delivers 
gyro-surveying data that increases drilling operation efficiency 
and  tool  reliability  while  improving  access  to  small-target 
reservoirs. Improving drilling efficiency also helps to reduce the 
environmental impacts of drilling operations by reducing the 
amount of time needed for operations.

Validated through extensive testing and field trials in the North 
Sea,  Ecuador,  Africa,  and  Far  East  Asia,  the  service  has 
produced  more  than  20,000  successful  surveys  with  zero 
failures. In Russia, GyroSphere service enabled a customer to 
avoid  wellbore  collisions  while  accessing  reservoirs  from 
existing  structures,  thereby  eliminating  the  drilling  risks 
associated with deploying conventional gyro surveys.

Integrated Drilling

Given  that  approximately  two-thirds  of  the  oil  discovered  is 
currently  left  in  the  ground,  the  application  of  customized 
technology is key to increasing cost-efficient field development. 
During  the  last  few  years,  the  industry  has  depended  on 
enhancements  of  discrete  drilling  technologies  to  improve 
drilling  performance.  Optimizing  drilling  efficiency,  however, 
demands expert knowledge of the workflow and every component 
of the system—from drill bit to top drive. The best way to achieve 
a new level of efficiency requires a holistic and collaborative 
approach to managing the entire drilling system.

Consider  that  in  the  Permian  Basin,  a  Schlumberger  study 
identified more than 4,000 separate steps in drilling a well that 
require over 200 workflows. Yet, when an operator integrates 
individual services from multiple providers, operational time 
and resources may not be optimized. And when resources such 
as the delivery of equipment and consumables are not optimized 
based on the unique needs of the operation, potential outcomes 
include  higher  operating  costs  and  an  unnecessarily  large 
environmental footprint.

Conventional  drilling  operations  often  introduce  planning 
inefficiencies  and  manually  intensive  workflows  that  can  be 
remedied by an integrated drilling system with digitally enabled 
hardware and software that leverages the value from all the data 
generated  during  operations.  In  the  planning  phase,  for 

example, the DrillPlan* coherent well construction planning 
solution learns from previous experiences to design the well and 
deliver a superior digital well plan. 

By combining the DrillPlan solution with the advanced operational 
control  in  the  OneDrill*  integrated  drilling  system,  drilling 
workflows  can  be  optimized  even  further.  This  is  particularly 
important  when  establishing  the  necessary  rig  schedule  to 
account for material use, delivery, and shipping, and determining 
inventory levels. Additional software within the OneDrill system 
handles  operations  management  tasks,  such  as  dispatching 
construction  activities,  detailed  scheduling,  and  assuring 
operational integrity to optimize resources. By streamlining the 
management of resources at the wellsite—such as equipment, 
consumables,  and  the  number  of  people—we  can  reduce 
transportation  requirements  and  decrease  fuel  consumption 
and CO2 emissions.

The OneDrill system will deliver increased levels of operational 
reliability and efficiency when deployed with the Schlumberger 
land  rig  of  the  future  and  its  unique  hardware  and  software 
platform. This land rig incorporates automated pipe handling and 
more than 1,000 sensors for equipment control, system health 
monitoring, and process monitoring. The sensors monitor and 
record  more  than  350  rig  activities  to  improve  operations 
reliability based on predictive health maintenance. Predictive 
maintenance extends equipment and tool life, reducing downtime 
and operating costs by taking proactive remedial action.

This schematic illustrates part of a digital workflow using the DrillPlan coherent well construction planning solution. The DrillPlan solution enables 
collaboration between the E&P company’s multidisciplinary well planning team and service company domain experts during various stages of the well 
planning process.

Technology Spotlight: HyperBlade Bit

The HyperBlade hyperbolic diamond element bit reduces drilling costs by increasing the rate of penetration with improved steering response in 
soft and plastic rock formations. The new technology incorporates the Hyper hyperbolic diamond cutting elements that cut 20% deeper into rock 
compared with conventional polycrystalline diamond compact cutters.

As operating environments become increasingly complex and 
remote, field equipment longevity, durability, and reliability are 
essential. Drillers need to be able to stay in control of downhole 
conditions,  and  the  drill  bit—the  part  of  the  bottomhole  
assembly (BHA) that cuts the rock to create the borehole—is a 
critical component in overall drilling efficiency. Diamond element 
technology  is  at  the  heart  of  the  Schlumberger  strategy  for 
optimal drilling performance.

Our strategic acquisition of Smith International in 2010 added 
synthetic  diamond  material  technology  and  manufacturing 
to  the  company  through  MegaDiamond,  a  Schlumberger 
company.  MegaDiamond  invented  the  first  polycrystalline 
diamond material, which was used to create polycrystalline 
diamond  compact  (PDC)  cutters  that  have  greatly  improved 
drilling  performance.  As  the  only  oilfield  service  company 
that  designs  and  manufactures  PDC  cutters,  Schlumberger 
is uniquely equipped to ensure that the development of our 
cutting elements is fully aligned with what our customers need 
to meet their drilling challenges.

In 2018, Schlumberger extended its Blade family of diamond 
element  bits  with  the  introduction  of  the  HyperBlade 
hyperbolic diamond element bit. The HyperBlade bit uses a  
3D  Hyper*  hyperbolic  diamond  cutting  element  with  
a  profile  that  cuts  more  than  20%  deeper  into  soft  and  
plastic formations. 

In these formation types, flat PDC cutters can be compromised 
when long ribbons of cuttings material impede the bit cutting 
structure. The Hyper element minimizes this effect by creating 
small cuttings chips through the combination of its hyperbolic 
geometry and the chip-breaking profile at the center of the 
element,  which  also  improves  cuttings  removal.  This  also 
helps the HyperBlade bit increase the rate of penetration (ROP)  
in  a  variety  of  drilling  environments  without  compromising 
steerability or directional tracking.

Technology  such  as  the  HyperBlade  bit  also  helps  limit  the 
environmental impacts of drilling operations because less time 
is spent drilling due to efficiency gains, which in turn decreases 
the emissions associated with drilling operations as well as  
a reduction in noise exposure.

HyperBlade bit technology helped to reduce drilling time for a 
customer in the Denver-Julesburg Basin in Colorado. In this soft 
formation, vertical, curve, and lateral sections of the wells are 
drilled in one run, with each run using one bit and one BHA. A BHA 
fitted with a HyperBlade bit proved to be an excellent solution. 

In  this  case,  the  HyperBlade  bit  achieved  an  average  ROP 
increase of 20% in three wells on two separate pads within the 
same field. In one well, there was a 50% improvement in ROP 
in the vertical section, which saved the operator 7.5 hours of 
drilling time compared with offset wells using conventional bits.

Integrated Completions

In North America, the expansion of unconventional resource 
development  has  benefitted  from  adopting  technologies  and 
processes, such as multistage completions, to improve operational 
efficiency  and  reduce  operating  costs.  Furthermore,  the 
integration  of  best-in-class  hydraulic  fracturing,  multistage 
completions,  and  pumpdown  perforating  technologies  is 
leading to increased operational efficiency and improved long-
term reservoir management. 

The  OneStim  integrated  completions  system  brings  domain 
experts  together  in  state-of-the-art  facilities  to  align  every 
aspect  of  the  well  completions  process,  from  operational 
planning  to  resource  management.  These  fully  integrated 
services start with mining, delivering, and managing proppant 
at the wellsite. The unique vertical integration of sand mines, 
trucking,  and  an  extensive  rail  network  ensure  on-time 

delivery  of  proppant  to  Schlumberger  North  American 
operations, optimizing logistics and fleet utilization. 

In the Eagle Ford Shale, OneStim helped a customer decrease 
pad-to-pad  mobilization  by  50%  and  more  than  double  the 
amount of stages placed per day. Integrating technologies such 
as the CAMShale* fracturing fluid delivery and flowback service 
reduced rig-up time—from three hours to less than 18 minutes. 
The  number  of  connections  needed  was  similarly  greatly 
reduced  by  using  Monoline*  flanged-connection  fracturing 
fluid delivery technology to conduct single-line rig-up.

Our  hydraulic  fracturing  technologies  are  helping  operators 
complete  more  stages  per  day  and  optimize  reservoir 
stimulation.  In  unconventional  reservoirs,  parent  wells  are 
initially drilled and subsequently followed by child, or infill, 
wells.  As  subsurface  dynamics  change  between  parent  and 
child  wells,  BroadBand  Shield*  fracture-geometry  control 

The automated stimulation delivery platform shown above incorporates a self-contained proppant delivery and storage system that streamlines OneStim 
materials management; improves health, safety, and environmental performance; and increases operational efficiency.

service and WellWatcher Stim* stimulation monitoring service 
make it possible to maintain the productivity of existing wells 
while  avoiding  detrimental  parent-child  well  interactions.  
For  a  customer  in  North  Dakota,  BroadBand  Shield  service 
helped overcome such an interaction during the stimulation of 
a  child  well,  saving  approximately  $400,000  in  intervention 
costs  and  more  than  two  weeks  of  deferred  production  in 
neighboring parent wells.

Through  vertical  integration  of  sand  supply  via  mining, 
logistics,  and  pumping  services  as  well  as  its  streamlined 
management  of  resources  and  operations,  the  OneStim 
system  enables  efficiencies  that  result  in  greater  cost 
savings. Our novel fluid and proppant technologies can also 
decrease the water and sand requirements for each well. On 
average, the HiWAY* flow-channel fracturing technique uses 
40%  less  proppant  in  hydraulic  fracturing  treatments. 

Compared with slickwater treatments, the HiWAY technique 
uses 25% less water, decreasing the environmental impacts 
at the wellsite.

The  environmental  impacts  of  well  completions  operations 
can  be  reduced  even  further  by  using  the  Schlumberger 
Stewardship Tool. This innovative software can evaluate every 
phase  of  a  well  completions  project  by  managing  risk, 
mitigating  pollution,  minimizing  waste,  and  lowering 
greenhouse gas emissions, among other considerations. The 
tool  provides  quantitative  results  based  on  specific  job 
information,  from  the  type  of  wellsite  equipment  needed  
and  how  it  is  powered,  to  water  and  chemical  usage.  The 
Stewardship Tool can assess 19 key performance indicators, 
which  are  aligned  with  the  Global  Reporting  Initiative,  an 
independent  international  standards  organization,  in  its  G4 
Sustainability Reporting Guidelines.

Technology Spotlight: Fulcrum Technology

Horizontal drilling has the potential to increase well productivity 
by exposing more of the reservoir to the wellbore, while also 
reducing  operational  costs  and  environmental  impacts.  In 
North America unconventional reservoirs, multistage hydraulic 
fracturing  is  the  preferred  completion  technique  for  long 
horizontal wells. 

Several factors affect the success of a fracturing treatment, 
one of which is cement quality. If there are any channels for 
fracturing fluid and pressure to escape behind the casing, the 
efficiency of the fracturing operations will be reduced.

Fulcrum  cement-conveyed  frac  performance  technology 
optimizes  hydraulic  isolation  in  the  horizontal  well  and 
enables more efficient fracturing without adding operational 
complication or cost. During cementing, Fulcrum technology 
interacts with the fluid that remains after drilling to reduce 
the potential for fluid communication through any channels. 
More efficient fracturing means less wasted fluid, proppant, 
and  energy—which  in  turn  reduces  environmental  impacts  
because less resources are needed. 

For example, after five horizontal wells with 10,000-ft laterals 
were  cemented  using  Fulcrum  technology  for  a  customer 
in  the  Permian  Basin,  measurements  of  the  quality  of  the 
cement  between  casing  and  formation  confirmed  superior 
zonal  isolation  compared  with  offset  wells  cemented  with 
conventional methods. OneStim hydraulically fractured these 
five wells and early production was compared with public data 

Researchers conduct lab tests on Fulcrum cement-conveyed frac 
performance technology. The Fulcrum system lowers the risk of fluid 
migration from zone to zone behind the casing, which is important in 
the isolation of hydraulic fracturing stages in horizontal wells.

from representative offset wells within a 10-mile radius that 
had been completed in the last two years using conventional 
stimulation methods. Normalized by lateral length, the mean 
three-month  cumulative  liquids  production  in  the  five  wells
treated with Fulcrum technology was 22% higher compared 
with the offset wells.

Digitally Enabled Well Testing

When we look to new sources of oil to meet demand and replace 
reserves, we must first confirm a reservoir’s capacity to produce 
oil and gas by conducting well tests. The results of these tests 
affect the accuracy of oil reserve estimates and help determine 
the efficiency of hydrocarbon recovery. However, conventional 
well testing presents several challenges—from environmental 
and safety considerations to the quality and quantity of the data 
collected.  Concert  performance  technology  addresses  these 
challenges by enabling well testing operations with real-time 
surface  and  downhole  measurements,  data  analysis,  and 
collaboration capabilities.

Concert performance technology uses sensors and cameras to 
acquire  data,  monitor,  and  analyze  surface  test  operations 
through mobile devices, web-based dashboards, and wearable 
technology. The data is made available to the customer using 
the web-based dashboard. When everyone is viewing the same 
data,  diagnostics,  and  analysis  in  real  time,  a  new  level  of 

collaboration  is  achieved.  Digitally  enabling  the  entire  
well  testing  process  decreases  workforce  exposure  by  
reducing the time needed to read sensors and monitor data 
locally.  Cameras  also  provide  continuous  video  surveillance  
of  burner  combustion  to  manage  fallout  and  emissions.  
The  result  is  safer  well  testing  operations  and  a  reduced 
environmental footprint.

For  example,  a  customer  developing  a  deepwater  gas 
condensate field offshore Australia that has multiple ultrahigh- 
rate wells required a dual testing system with two burners and 
more  than  twice  the  number  of  monitoring  stations.  The 
system also included pressure control valves more than 150 m 
from the well test area. The conventional approach would have 
required  one  crew  member  to  observe  each  burner  and 
perform numerous manual tasks to read gauges and collect 
and analyze samples. Instead, Concert performance technology 
enhanced  both  crew  safety  and  environmental  compliance  
by avoiding manual measurement and providing continuous 
real-time data and analysis of the well testing operation.

Field engineers review real-time data during well testing operations. The Concert well testing live performance includes mobile devices and wearable 
technology to enhance data analysis and collaboration at the wellsite.

changes in fluid flow inside the hydrocarbon processing plant.

Integrated Production Systems

A production system often requires several years to design and 
build,  which  delays  the  time  to  first  oil.  And  because  it  is 
inevitable that reservoir production changes over time, facilities 
must be designed to accommodate every challenging condition 
that  might  occur  during  the  field’s  productive  lifecycle.  This 
means  that  new  facilities  are  often  overdesigned,  leading  to 
additional  delays  and  capital  outlay  and  resulting  in  an 
environmental footprint that is larger than necessary. 

When  using  our  OneSurface®  reservoir-integrated  production 
system,  customers  can  improve  their  project  economics  by 
maximizing  recovery,  accelerating  production,  and  managing 
risk from the very beginning. With the OneSurface system, the 
process  begins  with  real-time  downhole  measurement  as  the 
vital  narrative  for  optimally  designing  surface  processing 
facilities that deliver first oil in months rather than years and 
then  proactively  match  and  manage  changes  in  production. 
OneSurface  is  built  on  the  synergy  of  Testing  Services  and 
Cameron Process Systems, and brings together leading downhole, 
surface, and digital technologies that enable teams to anticipate 
and react to any changes that might occur during production.

Once processing begins, information from the reservoir, surface, 
and  facility  stream  directly  into  a  cloud-based  environment.  
In  the  cloud,  reservoir  and  production  data  are  seamlessly 
integrated  and  analyzed  for  secure  access.  The  facility 

automatically  keeps  the  operational  team  informed  and  can 
respond to challenging live flow events faster than possible with 
human intervention. When dynamic reservoir changes occur, 
the facility easily incorporates leading process technologies to 
keep pace with production. This means that the customer can 
produce export-quality hydrocarbons at optimal levels without 
compromising cash flow for the life of the field. Flow assurance 
and production are continuously optimized by the OneSurface 
system’s ongoing integration of data analytics, process modeling, 
and the automation of best practices. 

One example of a OneSurface system is an onshore sour gas and 
liquids  early  production  facility  in  the  Middle  East  with  a 
processing  capacity  of  400  MMcf/d  of  gas  and  2,700  bbl/d  of 
liquids. This fast-track facility uses bacteria from the THIOPAQ 
O&G  process  to  eliminate  hydrogen  sulfide,  which  uses 
significantly less power and chemicals to treat gas compared 
with traditional methods. The bacteria consume the hydrogen 
sulfide in the gas stream and produce solid elemental sulfur  
that  can  be  used  for  agricultural  purposes.  The  OneSurface 
system also enables fast production shutdown and startup with 
minimal waste due to the simplicity of its design and operation, 
which further reduces the environmental impacts. Schlumberger 
achieved first gas for this facility in record time—14 months 
from the project award—by leveraging its processing technology 
and  engineering  and  domain  expertise.  This  is  one  among  
80 fast-track facilities that Schlumberger has designed, built, 
and commissioned globally.

Schlumberger Production Management

Although  most  of  our  work  is  performed  under  a  standard 
single-product-line contract in which we price our technologies 
separately, we can also provide technical support during the 
different phases of a customer’s project. This begins with our 
Integrated  Services  Management  (ISM)  for  which  specially 
trained  project  managers  provide  scheduling,  planning,  and 
activity  coordination  for  the  various  Schlumberger  product 
lines involved in the project. Another level is Integrated Drilling 
Services  (IDS),  which  includes  project  management, 
engineering  design,  and  technical  optimization  capabilities  
on contracts where commercial terms provide performance-
based compensation to Schlumberger. 

The  highest  level  of  integrated  services  that  we  provide  is 
through  the  Schlumberger  Production  Management  (SPM) 
model, created in 2011 to help develop and comanage customer 
assets  under  long-term  commercial  agreements.  In  the  SPM 
model,  we  assume  responsibility  for  full-field  management, 
combining our pore to pipeline portfolio of products and services 
with our technical expertise and operational experience. This 
model  fills  a  gap  in  the  market  that  exists  between  what  a 
traditional service company can offer and the business models 
that E&P companies currently use. SPM helps our customers 

develop or redevelop their fields to increase production, improve 
cash flow, and optimize reservoir recovery.

To  date,  approximately  10,000  wells  have  been  successfully 
brought to production through our global team of 2,000 oilfield 
specialists, which includes 850 engineers and 675 geoscientists. 
Today  we  comanage  approximately  250,000  bbl/d  of  oil 
equivalent production on 15 projects in four continents. Our 
primary focus is mature oil fields on land.

For example, in Alberta, Canada, SPM is increasing operations 
efficiency  and  well  productivity  in  the  Palliser  Block  by 
partnering  with  Torxen  Energy,  a  private  Canadian  E&P 
company. In 2018, we drilled 123 wells and decreased operating 
expenditures  by  30%  through  increased  efficiency  and  the 
integration  of  existing  asset  operations  with  SPM  into  a 
streamlined  and  more  collaborative  team.  The  total  field 
production rate has increased from 10,000 bbl/d to 21,000 bbl/d 
of oil through the adoption of new technologies and improved 
operational processes. To reduce the environmental impacts, 
high-bleed pneumatic actuators were replaced with low-bleed 
devices to minimize the total methane released, thus reducing 
the total carbon dioxide emissions (CO2E). A total of 881 devices 
were replaced in 2018, resulting in an estimated CO2E reduction 
of approximately 55,000 tons per year.

Stewardship Tool

Stakeholders discuss how the HiWAY flow-channel fracturing system can decrease not only water usage but also proppant quantities and wellsite 
equipment requirements—all of which reduces truck traffic and CO2 emissions. The image on the monitor shows the overall reduction in environmental 
footprint by adopting the optimized case (in blue) versus the conventional method, or base case (in red). 

The Stewardship Tool has attracted a high level of interest 
among our customers and other stakeholders as a potential tool 
for planning development scenarios and holding meaningful 
discussions about environmental impacts and how to minimize 
them. The software uses quantitative results to evaluate each 
phase of a project to manage risk, prevent pollution, minimize 
waste, and lower greenhouse gas emissions. 

Schlumberger also uses the Stewardship Tool to help embed 
sustainability into our engineering and operational practices. 
By modeling efficiency gains at the wellsite, we can enable 
our customers to drill faster and with better accuracy while 
lowering  environmental  impacts.  In  well  stimulation,  for 
example, emissions, air quality, water usage, noise, and chemical 
usage are among the 19 key performance indicators that can 
be measured and evaluated to reduce environmental impacts.

Once  a  base  case  is  established,  asset  owners  and  service 
providers can further optimize the individual components that 
affect  specific  environmental  concerns.  For  example,  truck 
traffic is related to the transport of equipment to the wellsite, 
delivery  of  water  and  proppant,  and  movement  of  flowback 
water from the location.

One option to decrease truck traffic would be piping water to 
the location rather than using trucks. Another option would 
be using the flowback water at the next wellsite instead of 

transporting  it  for  offsite  disposal.  As  stakeholders  adjust 
the options available, they can see how the optimized case 
compares with the base case already established. In addition, 
by  introducing  novel  technologies  engineered  to  reduce 
environmental impacts, we can further reduce truck traffic.

For  instance,  rather  than  using  conventional  hydraulic 
fracturing  methods,  the  HiWAY  flow-channel  fracturing 
technique combined with state-of-the-art crosslinked gel fluid 
technology can decrease not only water usage but also proppant 
quantities and wellsite equipment requirements—all of which 
would reduce truck traffic. A reduction in truck traffic translates 
into a reduction of CO2 emissions.

We are currently using the Stewardship Tool in completions-  
related  new  product  development  where  environmental 
aspects  are  a  critical  area  of  focus.  Additionally,  a  drilling 
module has been developed and is in the process of being 
rolled  out  to  drilling-related  product  development  centers. 
Externally,  we  are  introducing  the  Stewardship  Tool  to 
customers for use in development planning and stakeholder 
engagement activities.

For  more  information  on  the  Stewardship  Tool  and  other 
environmental,  social,  and  governance  (ESG)  initiatives,

The Key to Long-Term Success

Schlumberger  firmly  believes  that  technology  drives  E&P 
performance.  For  more  than  90  years,  we  have  used  our 
innovative technology and reservoir domain expertise to deliver 
solutions that help improve our customers’ performance. Now, 
with the large amount of data generated from oilfield operations, 
we are pairing our domain knowledge and expertise with data-
driven analytics to bring our customers a deeper and broader 
understanding of their entire reservoir development process to 
reduce risk and deliver full-cycle returns. 

The amount of data generated from operations is expected to 
increase exponentially, necessitating a secure way to manage 
and analyze it. The DELFI* cognitive E&P environment provides 
our  customers  with  an  ecosystem  that  supports  all  the  tools 
needed  to  manage  large  volumes  of  data.  Customers  can 
combine  their  data  and  petrotechnical  expertise  with  a 
Schlumberger E&P Data Lake on the Google™ Cloud Platform 
that includes data from more than 1,000 3D seismic surveys,  
5 million wells, 1 million well logs, and 400 million production 

records. Working with this information in the cloud enables our 
customers to take advantage of data analytics, machine learning, 
high  performance  computing,  and  the  IoT  to  maximize 
operational efficiency and optimize production. Furthermore, 
customers  and  software  partners  can  securely  add  their 
intellectual property and unique workflows to help create the 
best solution for their assets. 

Customers who engage Schlumberger integrated services are 
benefitting  from  project  derisking,  drilling  efficiency,  
effective  project  management,  and  integration  synergies. 
These benefits result in improved project cash flow, reduced 
operating costs, and accelerated development. The introduction 
of new digital technologies that leverage all available oilfield 
data is only the beginning of the journey toward the digitally 
enabled, fully integrated systems that will create a step change 
in E&P performance and reduce the environmental impacts of 
oilfield operations.

We are excited to continue to partner with our stakeholders on 
the journey to meet global E&P industry challenges.

A drilling engineer integrates wellbore engineering and geomechanical workflows in the DELFI cognitive E&P environment. These workflows include the 
generation of a mechanical earth model so that when a well trajectory design is changed, the wellbore stability analysis in the DrillPlan coherent well 
construction planning solution is automatically updated. This automated solution significantly reduces well planning time.

Item 1. Business.

All references in this report to “Registrant,” “Company,” “Schlumberger,” “we” or “our” are to Schlumberger
Limited (Schlumberger N.V., incorporated in Curaçao) and its consolidated subsidiaries.

Founded in 1926, Schlumberger is the world’s leading provider of technology for reservoir characterization,
drilling, production and processing to the oil and gas industry. Having invented wireline logging as a technique
today Schlumberger supplies the industry’s most
for obtaining downhole data in oil and gas wells,
from exploration through production, and integrated
comprehensive range of products and services,
pore-to-pipeline solutions that optimize hydrocarbon recovery to deliver
reservoir performance. As of
December 31, 2018, the Company employed approximately 100,000 people of over 140 nationalities operating in
more than 85 countries. Schlumberger has executive offices in Paris, Houston, London and The Hague.

Schlumberger operates in each of the major oilfield service markets,
through four segments: Reservoir
Characterization, Drilling, Production and Cameron. Each segment consists of a number of technology-based
service and product lines, or Technologies. These Technologies cover the entire life cycle of the reservoir and
correspond to a number of markets in which Schlumberger holds leading positions. The role of the Technologies

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
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 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 during each of 2018, 2017 and 2016.

opportunities for growth are essentially uniform across all services and products. Manufacturing and engineering

5

facilities as well as research centers are shared, and the labor force is interchangeable. Technological innovation,
quality of service and price differentiation are the principal methods of competition, which vary geographically
with respect to the different services and products offered. While Schlumberger has numerous competitors, both
large and small, Schlumberger believes it is an industry leader in providing geophysical equipment and services,
rig equipment, surface
wireline logging, well production testing, exploration and production software,
equipment, subsea equipment, artificial lift, hydraulic fracturing, cementing, coiled-tubing services, drilling and
completion fluids, solids control and waste management, drilling pressure control, drill bits, measurement-while-
drilling, logging-while-drilling, directional-drilling services, and surface data (mud) logging.

GENERAL

Intellectual Property

limited to patents,
Schlumberger owns and controls a variety of intellectual property,
proprietary information and software tools and applications that, in the aggregate, are material to Schlumberger’s
business. While Schlumberger seeks and holds numerous patents covering various products and processes, no
particular patent or group of patents is material to Schlumberger’s business.

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 fully utilize their
annual budgets.

Customers and Backlog of Orders

For the year ended December 31, 2018, no single customer exceeded 10% of consolidated revenue. Other than
the OneSubsea, Drilling Systems and WesternGeco businesses, Schlumberger has no significant backlog due to
the nature of its businesses. The combined backlog of these businesses was $2.7 billion at December 31, 2018 (of
which approximately 50% is expected to be recognized as revenue during 2019) and $2.5 billion at December 31,
2017.

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 our products and services is substantially dependent on the levels of expenditures by our
customers. A substantial or an extended decline in oil and gas prices could result in lower expenditures by
our customers, which could have a material adverse impact on our financial condition, results of
operations and cash flows.

Demand for 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. Declines, as well as
anticipated declines, in oil and gas prices could result in project modifications, delays or 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.

Historically, oil and natural gas prices have experienced significant volatility and can be affected by a variety of
factors, including:

demand for hydrocarbons, which is affected by general economic and business conditions;

the ability or willingness of the Organization of Petroleum Exporting Countries (“OPEC”) to set and
maintain production levels for oil;

oil and gas production levels by non-OPEC countries;

the level of excess production capacity;

political and economic uncertainty and geopolitical unrest;

the level of worldwide oil and gas exploration and production activity;

access to potential resources;

governmental policies and subsidies;

the costs of exploring for, producing and delivering oil and gas;

technological advances affecting energy consumption; and

weather conditions.

The oil and gas industry has historically experienced periodic downturns, which have been characterized by
diminished demand for our products and services as well as and downward pressure on the prices we charge.
Sustained market uncertainty can also result in lower demand and pricing for our products and services. A
significant downturn or sustained market uncertainty could result in a reduction in demand for oilfield services
and could adversely affect 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 69% of our consolidated revenue in 2018, 74% in
2017 and 80% in 2016. Operations in countries other than the United States are subject to various risks,
including:

(cid:129)

(cid:129)

(cid:129)

volatility in political, social and economic conditions;

exposure to expropriation of our assets or other governmental actions;

social unrest, acts of terrorism, war or other armed conflict;

confiscatory taxation or other adverse tax policies;

deprivation of contract rights;

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

exposure 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
to
certain persons. Our ability to transfer people, products and data among certain countries is subject
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
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

10

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, including catastrophic well incidents, 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. Catastrophic well incidents, including blow outs at a well site, may expose us to
additional liabilities. Generally, we rely on contractual indemnities, releases, limitations on liability with our
customers and insurance to protect us from potential liability related to such events. However, 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.

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

11

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 may adversely affect our operations.

Our business may be materially affected by severe weather 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, including systems operated by or under the
control of third parties. Although we devote significant resources to protect our systems and proprietary 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, or the systems of third parties for
protecting against cybersecurity risks are circumvented or breached, or we are subject to ransomware or other
attacks, this could result in disruptions to our business operations; unauthorized access to (or the loss of
Company access to) competitively sensitive, confidential or other critical data or systems; loss of customers;
financial losses; regulatory fines; misuse or corruption of critical data and proprietary information.

2018 Executive Overview

Schlumberger full-year 2018 revenue of $32.8 billion increased 8% over 2017. This revenue growth was driven
almost entirely by increased activity in North America against a backdrop of increasing oil prices throughout
most of the year.

In the oil markets, sentiment was stable and positive for the first three quarters of 2018, providing a rising oil
price environment. OECD crude and product stocks continued a downward trend that began in the third quarter
of 2016. Production cuts from OPEC and Russia in 2017 served to strengthen the oil price. Activity picked up
globally and, as oil reached its peak price for the year in October, production from major producers, including
unconventional US production, began to surprise to the upside. Output in Libya rebounded sharply; Saudi Arabia
and the United Arab Emirates each recorded record production output; and dispensations from the Iran export
sanctions generated aggregate production that more than offset declines elsewhere.

As a result, the market became oversupplied at the beginning of the fourth quarter despite the anticipated
slowdown in the Permian Basin production growth due to capacity takeaway constraints. This, coupled with
concerns about global oil demand, caused oil prices to plummet by more than 40% during the fourth quarter of
2018 and led to a sudden and sharp decrease in US land well completion activity during the final months of the
year.

In the natural gas markets, consumption of liquified natural gas (“LNG”) continued to rise enabled by vast
sources of new supply. The US became a LNG exporter in 2016, when the first shipment left Sabine Pass in
Louisiana. US export capacity grew to 37 million tonnes in 2018 and is set to nearly double in 2019.
Underground gas storage in the US was below average through most of 2018, however, rising gas production
from unconventional oil and gas wells in the US Northeast, Midcontinent and the Permian Basin helped to keep
Henry Hub prices well below international prices. This will allow the US to join Australia and the Middle East as
significant exporters.

Schlumberger financial performance in 2018 was driven largely by North America, where revenue of
$12.0 billion grew 26% year-over-year, despite the steep fall-off in activity during the fourth quarter of the year.
This growth was driven by increased land activity that primarily benefited Schlumberger’s OneStim business,
where revenue grew 41%.

Full-year 2018 international revenue of $20.4 billion was essentially flat compared with 2017. During the third
quarter of 2018, international revenue grew faster than North America revenue for the first time since 2014,
marking the beginning of a positive activity trend after three consecutive years of declining revenue. This was
driven by the increased activity of national oil companies (“NOCs”), as they began to invest in longer-term
resource development following a sustained period of deep underinvestment and declining production.

The dramatic fall in oil prices in the fourth quarter was largely driven by higher-than-expected US shale
production as a result of the surge in activity earlier in the year, and as geopolitics negatively impacted the global
demand- and supply-balance sentiments. The combination of these two factors, together with a large sell-off in
the equity markets due to concerns around global growth and increasing US interest rates, created a near-perfect
storm to close out 2018.

Looking ahead to 2019, Schlumberger expects a more positive supply- and demand-balance sentiment to lead to
a gradual recovery in the price of oil over the course of the year, as the OPEC and Russia production cuts take

full effect; the effect of lower activity in North America land in the second half of 2018 impacts production
growth; the dispensations from the Iran export sanctions expire and are not renewed; and as the US and China
continue to work toward a solution to their ongoing trade dispute.

In the meantime, the recent oil price volatility has introduced more uncertainty around the global exploration and
production (“E&P”) spending outlook for 2019, with customers generally taking a more conservative approach at
the start of the year. However, based on recent discussions with customers, Schlumberger is seeing clear signs
that E&P investments are starting to normalize and reflect a more sustainable financial stewardship of the global
resource base. For the North America land E&P operators, this means that future investments will likely be much
closer to the level that can be covered by free cash flow. Conversely, in the international markets apart from the
Middle East and Russia, after four years of underinvestment and a focus on maximizing cash flow, the NOCs and
independents are starting to see the need to invest in their resource base simply to maintain production at current
levels.

This means that even with the current oil price levels, Schlumberger expects solid, single-digit growth in the
international markets, while in North America land the increased cost of capital and focus on aligning
investments closer to free cash flow has introduced more uncertainty to the outlook for both drilling and
production activity.

Fourth-quarter revenue of $8.2 billion declined 4% sequentially driven by lower activity and pricing for most
Production- and Cameron-related businesses in North America land. Lower revenue from OneSubsea also
contributed to the decline. International activity remained resilient despite the oil price drop, with revenue
increasing 1% sequentially. The seasonal slowdown in Russia was offset by increased revenue in the Middle
East, Asia and Africa. Revenue from Europe and Latin America was flat compared with the previous quarter.
Sequential performance was heavily impacted by Production- and Cameron-related activity declines in North
America land, as seen by the 12% sequential decrease of revenue in North America. OneStim revenue dropped
25% sequentially as a number of fleets were warm-stacked during the latter part of the quarter, and as
Schlumberger focused on securing dedicated contracts for the first half of 2019 early in the fourth-quarter
tendering cycle.

Reservoir Characterization

Fourth-quarter revenue of $1.7 billion decreased 1% sequentially driven by the seasonal decline in Wireline
activity in Russia, lower Wireline exploration activity offshore North America, and reduced OneSurface activity
in the Middle East. These effects were partially offset by year-end sales of SIS software.

Reservoir Characterization pretax operating margin of 22% was essentially flat compared with the previous
quarter as the effect of high-margin SIS software sales was offset by the seasonal decline in higher-margin
Wireline revenue.

Drilling

Fourth-quarter revenue of $2.5 billion increased 1% sequentially driven primarily by international growth in
Drilling & Measurements and M-I SWACO, while Drilling revenue remained resilient in North America land.

Drilling pretax operating margin of 13% decreased 105 basis points (“bps”) sequentially due to a seasonal
activity decline in Russia and the increased cost of mobilizing additional resources as IDS project activity scaled
up across international operations.

Production

Fourth-quarter revenue of $2.9 billion declined 10% sequentially. OneStim revenue in North America land
dropped 25%, accounting for the vast majority of the Production revenue decrease, as a number of fleets were
warm-stacked during the latter part of the quarter due to market oversupply conditions.

Production pretax operating margin of 7% decreased 310 bps sequentially due to reduced pricing and activity in
the OneStim business in North America land.

Cameron

Cameron revenue of $1.3 billion declined 3% sequentially as increased international sales in Surface Systems
were more than offset by lower revenue from the OneSubsea and Valves & Measurement product lines.
OneSubsea booked more than $600 million in new project orders during the fourth quarter of 2018, indicating
that it is now close to the cycle trough of backlog-driven activity.

Cameron pretax operating margin of 10% declined 140 bps sequentially due to lower OneSubsea margins.

Full-year 2018 revenue of $32.8 billion increased 8% year-on-year and grew for the second successive year.
Performance was driven by North America where revenue of $12.0 billion increased 26% due to the OneStim
business, which grew by 41%. Full-year international revenue of $20.4 billion was essentially flat compared with
2017.

Full-year 2018 pretax operating income of $4.2 billion grew 7% year-on-year. Pretax operating margin of 13%
was essentially flat with the previous year, as the impact of higher revenue was offset by reactivation and
mobilization costs associated with the ramp-up and strategic positioning for increased activity in both North
America and internationally.

Reservoir Characterization

Full-year 2018 revenue of $6.5 billion decreased 4% year-on-year primarily due to reduced OneSurface revenue
following the end of the first phase of an integrated production system project in the Middle East and reduced
WesternGeco activity as marine seismic acquisition contracts wound down during 2018 following the fourth
quarter 2017 decision to cease all future marine seismic acquisition activities after satisfying Schlumberger’s
remaining commitments.

20

Year-on-year, pretax operating margin increased 303 bps to 21% primarily as a result of reduced depreciation
and amortization following the WesternGeco impairment charges recorded in the fourth quarter of 2017.

Drilling

Full-year 2018 revenue of $9.3 billion increased 10% year-on-year primarily due to higher demand for
directional drilling technologies on land in North America and the start of new integrated drilling projects
internationally. This benefited Drilling & Measurements, Bits & Drilling tools, M-I SWACO and Integrated
Drilling Services.

Year-on-year, pretax operating margin declined 32 bps to 13%.

Production

Full-year 2018 revenue of $12.4 billion increased 17% year-on-year with most of the revenue increase
attributable to the accelerated land activity growth in North America that benefited the OneStim pressure
pumping businesses in North America land for the first three quarters of 2018. Growth was driven by the
deployment of additional hydraulic fracturing capacity, market share gains, operational efficiency improvements
and improved pricing.

Year-on-year, pretax operating margin declined 32 bps to 8%.

Cameron

Full-year 2018 revenue of $5.2 billion decreased 1% year-on-year. A 15% revenue increase in the short-cycle
business of Surface Systems, driven by higher North America land activity, was offset by a 12% decline in the
long-cycle OneSubsea business.

Year-on-year, pretax operating margin of 12% declined 232 bps due primarily to the decline in high-margin
OneSubsea project volumes.

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 Cameron, 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 2017 pretax operating margin was expanded 111 bps to 13%, as improved profitability in North
America due to the land activity growth that benefited Production and Drilling was offset by margin declines in
Reservoir Characterization and Cameron.

Reservoir Characterization

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%.

Drilling

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

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 SPM production levels in Ecuador partially offset the revenue increase.

Year-on-year, pretax operating margin increased 298 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

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

22

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

The decrease in interest income in 2018 compared to 2017 is primarily attributable to lower cash and short-term
investment balances.

Interest Expense

Interest expense of $575 million in 2018, $566 million in 2017 and $570 million in 2016 has been essentially
flat.

Other

Research & engineering and General & administrative expenses, as a percentage of Revenue, were as follows:

Income Taxes

The Schlumberger effective tax rate was 17% in 2018, (28)% in 2017, and 15% in 2016.

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 increases, the Schlumberger effective tax rate
generally decreases. Conversely, when the percentage of pretax earnings generated outside of North America
decreases, the Schlumberger effective tax rate generally increases.

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 changed US corporate income tax laws by, among other things, reducing the US corporate income
tax rate from 35% 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.

The effective tax rate for each of 2017 and 2016 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

23

impact of these charges and credits, the effective tax rate was 17% in 2018, 18% in 2017 and 16% in 2016. The
decrease in the effective tax rate in 2018 as compared to 2017, excluding the impact of charges and credits, was
primarily due to the impact of US tax reform. 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 compared to 2016.

Charges and Credits

Schlumberger recorded significant charges and credits during 2018, 2017 and 2016. 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 $340 million during 2018, $455 million during 2017 and $850 million
during 2016.
“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.

Key liquidity events during 2018, 2017 and 2016 included:

Cash flow from operations was $5.7 billion in 2018, $5.7 billion in 2017 and $6.3 billion in 2016.
Operating cash flows for 2018 were essentially flat compared to 2017 as the lower consumption of
working capital was offset by decreased depreciation and amortization following the asset impairment
charges recorded during the fourth quarter of 2017. The improvement in working capital in 2018 was
largely driven by strong accounts receivable collections. The decrease in operating cash flows in 2017
as compared to 2016 was largely attributable to lower earnings before consideration of non-cash charges
and credits and depreciation and amortization expense.

On July 18, 2013, the Board approved a $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 $723 million of Schlumberger common stock under this program as of December 31,
2018.

Dividends paid during 2018, 2017 and 2016 were $2.8 billion, $2.8 billion and $2.6 billion, respectively.

Capital expenditures were $2.2 billion in 2018, $2.1 billion in 2017 and $2.1 billion in 2016. Capital
expenditures during 2019 are expected to range between $1.5 billion and $1.7 billion.
During the fourth quarter of 2018, Schlumberger issued €600 million of 1.00% Guaranteed Notes due
2026.

During the fourth quarter of 2018, Schlumberger completed the divestiture of its marine seismic
acquisition business for net proceeds of $579 million (after considering $21 million of cash divested).

During the fourth quarter of 2017, Schlumberger issued $500 million of 2.20% Guaranteed Notes due
2020 and $600 million of 2.65% Guaranteed Notes due 2022.

During 2018, 2017 and 2016, Schlumberger made contributions of $83 million, $133 million and
$174 million, respectively, to its postretirement benefit plans. The US pension plans were 88% funded
at both December 31, 2018 and December 31, 2017 based on their projected benefit obligations.

Schlumberger’s international defined benefit pension plans were a combined 97% funded at both
December 31, 2018 and December 31, 2017 based on their projected benefit obligations.

Schlumberger expects to contribute approximately $25 million to its postretirement benefit plans in
2019, subject to market and business conditions.

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.

Schlumberger paid $2.8 billion of cash in connection with its 2016 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 2016 acquisition of Cameron, Cameron was 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;
$1.6 billion of 3.00% Senior Notes due 2020;
$850 million of 3.63% Senior Notes due 2022; and
$1.75 billion of 4.00% Senior Notes due 2025.

As of December 31, 2018, Schlumberger had $2.8 billion of cash and short-term investments on hand.
Schlumberger also has separate committed credit facility agreements aggregating $6.5 billion with commercial
banks, of which $4.1 billion was available and unused as of December 31, 2018. The $6.5 billion of committed
credit facility agreements support commercial paper programs. Schlumberger believes these amounts are
sufficient to meet future business requirements for at least the next 12 months.

The total outstanding commercial paper borrowings were $2.4 billion as of December 31, 2018 and $3.0 billion
as of December 31, 2017.

Excludes interest on $2.8 billion of variable rate debt, which had a weighted average interest rate of 3.5% as of
December 31, 2018.

(3) Represents an estimate of contractual obligations in the ordinary course of business. Although these contractual
obligations are considered enforceable and legally binding, the terms generally allow Schlumberger the option to
reschedule and adjust its requirements based on business needs prior to the delivery of goods.

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, 2018 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
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 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.

29

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
industry downturn. Schlumberger operates in more than 85 countries. As of December 31, 2018, only three 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.

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.

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 or more 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.

Schlumberger elected to perform the qualitative assessment described above for purposes of its annual goodwill
impairment test in 2018. Based on this assessment, Schlumberger concluded 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
the carrying value may not be
impairment whenever events or changes in circumstances indicate that

30

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
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 that 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.

Revenue Recognition for Certain Long-lived Construction-type Contracts

Schlumberger recognizes revenue for certain long-term construction-type contracts over time. These contracts
involve significant design and engineering efforts in order to satisfy custom designs for customer-specific
applications. Under this 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.
Approximately 5% and 7% of Schlumberger’s revenue in 2018 and 2017, respectively, was recognized under this
method.

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.

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, 2018 and 2017 was $601 million and $727 million, 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
library, surveys are primarily analyzed for

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)

(cid:129)

(cid:129)

The discount rate utilized to determine the liability for Schlumberger’s United States pension plans
and postretirement medical plan was 4.30% at December 31, 2018 and 3.70% at December 31, 2017.

The weighted-average discount
international pension plans was 4.00% at December 31, 2018 and 3.55% at December 31, 2017.

rate utilized to determine the liability for Schlumberger’s

The weighted-average discount rate utilized to determine expense for Schlumberger’s United States
pension plans and postretirement medical plan decreased from 4.20% in 2017 to 3.70% in 2018.

The weighted-average discount rate utilized to determine expense for Schlumberger’s international
pension plans decreased from 4.13% in 2017 to 3.55% in 2018.

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 2018 and 2017. The
weighted average expected rate of return on plan assets for the international pension plans was 7.40% in both
2018 and 2017. 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 2018 postretirement medical expense was 7.00%, 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,
2018 was 7.00%, 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 80% of Schlumberger’s revenue in 2018 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, 2018 market rates would increase the unrealized
value of Schlumberger’s forward contracts by $132 million. Conversely, a 10% depreciation in the US dollar
from the December 31, 2018 market rates would decrease the unrealized value of Schlumberger’s forward
contracts by $143 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, 2018, contracts were outstanding for the US dollar equivalent of $5.0 billion in various foreign
currencies, of which $1.9 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, 2018, Schlumberger had fixed rate debt aggregating approximately $13.2 billion and variable rate
debt aggregating approximately $2.8 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 $1.3 billion at December 31, 2018, 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. The average return on investments was 2.3% in 2018.

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, the 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 for certain long-term construction-type contracts over time; recoverability of fixed assets, goodwill,
intangible assets, Schlumberger Production Management investments and investments in affiliates; 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.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update
(“ASU”) 2014-09, Revenue from Contracts with Customers. This ASU amended the existing accounting
standards for revenue recognition and requires companies to recognize revenue when control of the promised
goods or services is transferred 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 using the
modified retrospective transition method applied to those contracts which were not completed as of January 1,
2018. Prior period amounts have not been adjusted and continue to be reflected in accordance with
Schlumberger’s historical accounting. The adoption of
impact on
Schlumberger’s Consolidated Financial Statements.

this ASU did not have a material

Schlumberger recognizes revenue upon the transfer of control of promised products or services to customers at
an amount that reflects the consideration it expects to receive in exchange for these products or services. The vast
majority of Schlumberger’s services and product offerings are short-term in nature. The time between invoicing
and when payment is due under these arrangements is generally between 30 to 60 days.

Revenue is occasionally generated from contractual arrangements that include multiple performance obligations.
Revenue from these arrangements is allocated to each performance obligation based on its relative standalone
selling price. Standalone selling prices are generally determined based on the prices charged to customers or
using expected costs plus margin.

Revenue is recognized for certain long-term construction-type contracts over time. These contracts involve
significant design and engineering efforts in order to satisfy custom designs for customer-specific applications.
Revenue is recognized as work progresses on each contract. Progress is measured by the ratio of actual costs

43

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. Due to the nature of these
projects, adjustments to estimates of contract revenue and total contract costs may be required as work
progresses. Progress billings are generally issued upon completion of certain phases of work as stipulated in the
contract. Any expected losses on a project are recorded in full in the period in which they become probable.

Due to the nature of its businesses, Schlumberger does not have significant backlog. Total backlog was
$2.7 billion at December 31, 2018, of which approximately 50% is expected to be recognized as revenue during
2019.

Short-term Investments

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 fair value.

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.

Equity and cost method investments 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
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

44

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 2018, 2017 and 2016.

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 $568 million, $465 million and
$449 million in 2018, 2017 and 2016, respectively.

The unamortized portion of Schlumberger’s investments in SPM projects was $4.201 billion and $4.065 billion at
December 31, 2018 and 2017, 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, receivables from clients and derivative financial instruments. Schlumberger places its cash and
short-term investments 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 22% of Schlumberger’s accounts
receivable balance at December 31, 2018. No other country accounted for greater than 10% of Schlumberger’s
accounts receivable balance.

3. Charges and Credits

Schlumberger recorded the following charges and credits during 2018, 2017 and 2016:

2018

(cid:129)

During the fourth quarter of 2018, Schlumberger completed the divestiture of its marine seismic
acquisition business to Shearwater GeoServices (“Shearwater”) for $600 million of cash and a 15%
equity interest in Shearwater. As a result of this transaction, Schlumberger recognized a $215 million
gain. This gain is classified in Gain on sale of business in the Consolidated Statement of Income (Loss).

46

(cid:129)

(cid:129)

During the fourth quarter of 2018, Schlumberger recorded $172 million of charges to fully impair
certain long-lived assets. This amount
is classified in Impairments & other in the Consolidated
Statement of Income (Loss).

During the second quarter of 2018, Schlumberger recorded a $184 million charge associated with
workforce reductions, primarily to further streamline its support cost structure. This charge is classified
in Impairment & other in the Consolidated Statement of Income (Loss).

The following is a summary of these charges and credits.

During the fourth quarter of 2017, Schlumberger decided to cease all future marine seismic acquisition
activities, after satisfying its remaining contractual commitments. 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 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 certain promissory notes, $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.

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
workforce 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

47

(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.
Although the $76 million net charge represented what Schlumberger believed was 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 was considered provisional. During 2018, Schlumberger finalized its
accounting for this matter and concluded that no material adjustments were required. 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.

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. Following the $105 million other-than-temporary
impairment charge described above, the new cost basis of these promissory notes was $135 million,
which approximated their fair value at December 31, 2017. Schlumberger sold these promissory notes
during the fourth quarter of 2018, which resulted in an immaterial loss.

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 workforce 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.
As a result, Schlumberger recorded a $646 million charge during the second quarter of 2016. During the
fourth quarter of 2016, Schlumberger further reduced its workforce in order to streamline its support
cost structure and recorded an additional $234 million charge 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 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.

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. 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.

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.

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

issued by Schlumberger

At December 31, 2018, Schlumberger had separate committed credit facility agreements aggregating $6.5 billion
with commercial banks, of which $4.1 billion was available and unused. These committed facilities support
commercial paper programs in the United States and Europe, and $1.0 billion matures in February 2019,
$1.5 billion matures in November 2020, $2.0 billion matures in February 2022 and $2.0 billion matures in
February 2023. Interest rates and other terms of borrowing under these lines of credit vary from country to
country.

During the fourth quarter of 2018, Schlumberger issued €600 million of 1.00% Guaranteed Notes due 2026.

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 these obligations for longer than one year. Borrowings under the commercial paper programs at
December 31, 2018 were $2.4 billion, all of which was classified within Long-term debt in the Consolidated
Balance Sheet. At December 31, 2017, borrowings under the commercial paper programs were $3.0 billion, of

56

which $1.7 billion was classified within Long-term debt and $1.3 billion was classified in Short-term borrowings
and current portion of long-term debt in the Consolidated Balance Sheet.

The weighted average interest rate on variable rate debt as of December 31, 2018 was 3.5%.

Long-term Debt as of December 31, 2018 is due as follows: $2.1 billion in 2020, $3.1 billion in 2021,
$4.4 billion in 2022, $2.1 billion in 2023, $1.8 billion in 2025, $0.7 billion in 2026 and $0.4 billion thereafter.

The fair value of Schlumberger’s Long-term Debt at December 31, 2018 and December 31, 2017 was
$14.6 billion and $15.2 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.

This cross-currency swap is designated as a fair value hedge of the underlying debt and is marked to market with
gains and losses recognized immediately in income to largely offset the effects of changes in the fair value of the
hedged debt.

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 cash flow hedges. The changes in the fair values of the hedges are
recorded on the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss. Amounts recorded
in Accumulated Other Comprehensive Loss are reclassified to earnings in the same periods that the underlying
hedged item is recognized in earnings.

At December 31, 2018, Schlumberger had fixed rate debt aggregating $12.7 billion and variable rate debt
aggregating $3.4 billion, after taking into account the effect of interest rate swaps.

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 79% of Schlumberger’s revenues in 2018 was denominated
in US dollars. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in

57

foreign currencies. Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of
the countries in which Schlumberger conducts business,
increase
(decrease).

the US dollar–reported expenses will

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.

At December 31, 2018, Schlumberger recognized a cumulative net $12 million loss 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 (Loss), as are changes in the fair value of
the hedged item. Transaction gains of $1 million in 2018 and transaction losses of $17 million and $93 million in
2017 and 2016, respectively, were recognized in the Consolidated Statement of Income (Loss) net of related
hedging activities. Included in the 2016 amount was $63 million of losses relating to Egypt. See Note 3—
Charges and Credits for further details.

At December 31, 2018, contracts were outstanding for the US dollar equivalent of $5.0 billion in various foreign
currencies, of which $1.9 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, 2018 and 2017.

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 10 years, and the options generally vest in increments over five years.

60

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-

$15 million, $26 million and $45 million, respectively.

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 awarded. If Schlumberger
falls below the threshold award performance level, no shares will be awarded. As of December 31, 2018, 1.9 million
performance share units were outstanding 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.

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, 2018 and 2017 were net of valuation allowances relating to net
operating losses in certain countries of $87 million and $119 million, respectively.

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.

A reconciliation of the beginning and ending amount of liabilities associated with uncertain tax positions for the
years ended December 31, 2018, 2017 and 2016 is as follows:

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.

15. Leases and Lease Commitments

During the fourth quarter of 2018, Schlumberger adopted ASU No. 2016-02, Leases, effective January 1, 2018.
This ASU requires lessees to recognize an operating lease asset and a lease liability on the balance sheet, with the
exception of short-term leases.

Under the transition method selected by Schlumberger, leases existing at, or entered into after, January 1, 2018
were required to be recognized and measured. Prior period amounts have not been adjusted and continue to be
reflected in accordance with Schlumberger’s historical accounting. The adoption of this standard resulted in the
recording of operating lease assets and operating lease liabilities of approximately of $1.3 billion as of January 1,
2018, with no related impact on Schlumberger’s Consolidated Statement of Equity or Consolidated Statement of
Income (Loss). Short-term leases have not been recorded on the balance sheet.

65

Schlumberger elected the package of practical expedients permitted under the transition guidance within the new
standard which, among other things, allows companies to carry forward their historical lease classification.

Schlumberger’s leasing activities primarily consist of operating leases for administrative offices, manufacturing
facilities, research centers, service centers, sales offices and certain equipment. Total operating lease expense,
which approximates cash paid and includes short-term leases, was $1.7 billion in 2018, $1.4 billion in 2017, and
$1.2 billion in 2016.

Future minimum rental commitments under noncancelable operating leases as of December 31, 2017 were as

Operating lease assets of $1.8 billion as of December 31, 2018 were included in Other Assets in the Consolidated
Balance Sheet.

The weighted-average remaining lease term as of December 31, 2018 was 7 years. The weighted-average
discount rate used to determine the operating lease liability as of December 31, 2018 was 3.2%.

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.

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
(“ABO”) represents the actuarial present value of benefits based on employee service and compensation, but
does not include an assumption about future compensation levels.

Actuarial gains arising during 2018 are primarily attributable to the increase in the discount rate used to
determine the PBO. As of December 31, 2018, the PBO and fair value of plan assets for plans with PBOs in
excess of plan assets were $11.0 billion and $9.9 billion, respectively. The related ABO for these plans was
$10.6 billion at December 31, 2018.

The weighted-average allocation of plan assets and the target allocations by asset category are as follows:

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, 2018 and 2017, by asset category, is
presented below and was determined based on valuation techniques categorized as follows:

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 $25 million to its
postretirement benefit plans in 2019, 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 . . . . . . . . . . . . .

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, 2018. 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, 2018, 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, 2018 has been
audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their
report which appears herein.

77

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, 2018 and 2017, 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
December 31, 2018,
including the related notes (collectively referred to as the “consolidated financial
statements”). We also have audited the Company’s internal control over financial reporting as of December 31,
2018, 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, 2018 and 2017 and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 2018 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, 2018, 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

78

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.

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.

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
information required to be disclosed in the reports that Schlumberger files or submits under the Exchange Act is

80

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 2018 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 2018 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.
