PART I

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 supplier of technology, integrated project management and information solutions to the international oil and gas exploration and production industry. Having invented wireline logging as a technique for obtaining downhole data in oil and gas wells, Schlumberger today provides the industry’s widest range of products and services from exploration through production. As of December 31, 2015, the Company employed approximately 95,000 people of over 140 nationalities operating in approximately 85 countries. Schlumberger has principal executive offices in Paris, Houston, London and The Hague.  

On August 26, 2015, Schlumberger and Cameron International Corporations (Cameron) jointly announced that they had entered into a definitive merger agreement in which Cameron will merge with an indirect wholly-owned subsidiary of Schlumberger in a stock and cash transaction. Under the terms of the agreement, Cameron shareholders will receive 0.716 shares of Schlumberger common stock and a cash payment of $14.44 in exchange for each Cameron share of common stock outstanding. Schlumberger estimates that it will issue approximately 137 million shares of its common stock and pay cash of approximately $2.8 billion in connection with this transaction. In November 2015, the US Department of Justice cleared the proposed merger without any conditions.  On December 17, 2015, Cameron stockholders voted to adopt the proposed merger.  However, the transaction remains subject to certain regulatory approvals and other customary closing conditions. It is anticipated that the closing of the transaction will occur in the first quarter of 2016.

Cameron designs, manufactures, markets and services equipment used by the oil and gas industry and industrial manufacturing companies. Cameron is a leading international manufacturer of oil and gas pressure control and separation equipment, including valves, wellheads, controls, chokes, blowout preventers and assembled systems for oil and gas drilling, production and transmission used in onshore, offshore and subsea applications and provides oil and gas separation, metering and flow measurement equipment. Cameron reported revenue of $10.4 billion for the year ended December 31, 2014.

Schlumberger operates in each of the major oilfield service markets, managing its business through three Groups: Reservoir Characterization, Drilling and Production.  Each Group 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 business is also reported through four geographic Areas: North America, Latin America, Europe/CIS/Africa and Middle East & Asia. Within these Areas, a network of GeoMarket* regions provides logistical, technical and commercial coordination.

The role of the Groups and Technologies is to support Schlumberger in providing the best possible service to customers and that it remains at the forefront of technology development.  The Groups and Technologies are collectively responsible for driving excellence in execution throughout their businesses, overseeing operational processes, resource allocation, personnel and delivering superior financial results. The GeoMarket structure offers customers a single point of contact at the local level for field operations and brings together geographically focused teams to meet local needs and deliver customized solutions. The Areas and GeoMarkets are responsible for providing the most efficient and cost effective support possible to the operations.

The Groups are as follows:

Reservoir Characterization Group – Consists of the principal Technologies involved in finding and defining hydrocarbon resources.  These include WesternGeco, Wireline, Testing Services, Software Integrated Solutions (SIS) and Integrated Services Management (ISM).

3

Drilling Group – Consists of the principal Technologies involved in the drilling and positioning of oil and gas wells and comprises Bits & Drilling Tools, M-I SWACO, Drilling & Measurements, Land Rigs and Integrated Drilling Services.

Production Group – Consists of the principal Technologies involved in the lifetime production of oil and gas reservoirs and includes Well Services, Completions, Artificial Lift, Well Intervention, Water Services, Integrated Production Services and Schlumberger Production Management.

SPM commercial arrangements create 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 Schlumberger’s customers’ assets 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 generally compensated based upon cash flow generated or on a fee-per-barrel basis.  This may include certain arrangements whereby Schlumberger is only compensated based upon incremental production that it helps deliver above a mutually agreed baseline.

Schlumberger also has a 40% equity ownership interest in OneSubsea^TM, a joint venture with Cameron.  The joint venture manufactures and develops products, systems and services for the subsea oil and gas market.  Schlumberger’s 40% share of the net income of the joint venture is reflected in the results of the Production Group.

4

Supporting the Technologies is a global network of research and engineering centers. Through this organization, Schlumberger is committed to advanced technology programs that enhance oilfield efficiency, lower finding and producing costs, improve productivity, maximize reserve recovery and increase asset value while accomplishing these goals in a safe and environmentally sound manner.

Schlumberger primarily uses its own personnel to market its offerings. The customer base, business risks and opportunities for growth are essentially uniform across all services. There is a sharing of manufacturing and engineering facilities as well as research centers, 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 offered. While there are numerous competitors, both large and small, Schlumberger believes that it is an industry leader in providing geophysical services, wireline logging, well testing, exploration and production software, drilling and completion fluids, solids and waste management, coiled-tubing, drill bits, measurement-while-drilling, logging-while-drilling, directional drilling services and mud logging. A large proportion of Schlumberger offerings is non-rig related; consequently, revenue does not necessarily correlate to the rig count.

GENERAL

Intellectual Property

Schlumberger owns and controls a variety of intellectual property, including but not limited to patents, 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 considered 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 typically result in temporarily reduced levels of activity. In addition, hurricanes and typhoons can disrupt coastal and offshore operations. Furthermore, customer spending patterns for multiclient data, software and other oilfield services and products generally result in higher activity in the fourth quarter of each year as clients seek to utilize their annual budgets.

Customers and Backlog of Orders

For the year ended December 31, 2015, no single customer exceeded 10% of consolidated revenue. Other than WesternGeco, Schlumberger has no significant backlog due to the nature of its businesses. The WesternGeco backlog, which is based on signed contracts with customers, was $1.1 billion at December 31, 2015 ($0.7 billion at December 31, 2014).

Financial Information

Financial information by business segment and geographic area for the years ended December 31, 2015, 2014 and 2013 is provided in Note 17 of the Consolidated Financial Statements.

Executive Officers of Schlumberger

The following table sets forth, as of January 27, 2016, the names and ages of the executive officers of Schlumberger, including all offices and positions held by each for at least the past five years.

Item 1A. Risk Factors.

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

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

Demand for the majority of our services is substantially dependent on the levels of expenditures by the oil and gas industry.  The current significant oil and gas industry downturn has resulted in reduced demand for oilfield services, which has had, and may continue to have, a significant adverse impact on our financial condition, results of operations and cash flows. If these conditions worsen or oil and gas prices do not improve, further reductions in spending by the oil and gas industry could have a material adverse effect on our financial condition, results of operations and cash flows.

Demand for the majority of our services depends substantially on the level of expenditures by the oil and gas industry for the exploration, development and production of oil and natural gas reserves. These expenditures are generally dependent on the industry’s view of future oil and natural gas prices and are sensitive to the industry’s view of future economic growth and the resulting impact on demand for oil and natural gas. Since 2014, oil and gas prices have declined significantly, resulting in lower expenditures by the oil and gas industry.  As a result, many of our customers have reduced or delayed their oil and gas exploration and production spending, reducing the demand for our services and exerting downward pressure on the prices that we charge.  These conditions have had, and may continue to have, an adverse impact on our financial condition.  

Continued low oil and gas prices or a further decline in oil and gas prices could cause a reduction in cash flows for our customers, which could have significant adverse effects on the financial condition of some of our customers. This 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.

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

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

7

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 approximately 85 countries in which we operate.

Our non-United States operations accounted for approximately 76% of our consolidated revenue in 2015, 71% in 2014 and 73% in 2013. Operations in countries other than the United States are subject to various risks, including:

We completed the wind down of our service operations in Iran during the second quarter of 2013. Prior to this, certain of our non-US subsidiaries provided oilfield services to the National Iranian Oil Company and certain of its affiliates (“NIOC”). We have reclassified the results of this business as a discontinued operation. All prior periods have been restated accordingly.

Our residual transactions or dealings with the government of Iran during 2015 consisted of payments of taxes and other typical governmental charges. Certain of our non-US subsidiaries maintained 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 maintains an account at Tejarat for payment of local expenses such as taxes and utilities. We anticipate that we will discontinue our dealings with Saderat and Tejarat following the receipt of all amounts owed to us for prior services rendered in Iran.

Our failure to comply with Foreign Corrupt Practices Act (“FCPA”) and other laws could have a negative impact on our ongoing 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 sanction laws that restrict certain operations in various countries or with certain persons.  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 and violating applicable laws and regulations.  Any determination that we have violated or are responsible for violations of anti-bribery or anti-corruption laws could have a material adverse effect on our financial condition.  Violations of international and US laws and regulations may result in fines and penalties, criminal sanctions, administrative remedies, restrictions on business conduct and could have a material adverse effect on our reputation and our business, operating results and financial condition.

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

8

discovery of previously unknown contamination or the imposition of new or increased requirements could require us to incur costs or become the basis of new or increased liabilities that could reduce our earnings and our cash available for operations.

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

The technical complexities of our operations expose us to a wide range of significant health, safety and environmental risks. Our offerings involve production-related activities, radioactive materials, chemicals, explosives and other equipment and services that are deployed in challenging exploration, development and production environments. An accident involving these services or equipment, or a failure of a product, could cause personal injury, loss of life, damage to or destruction of property, equipment or the environment, or suspension of operations. Our insurance may not protect us against liability for some 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 are subject to substantial deductibles, could adversely affect our financial condition, results of operations and cash flows.

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 services. This may, in turn, adversely affect our financial condition, results of operations and cash flows.

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

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 services, maintain market share, and negotiate acceptable contract terms with our customers.  If we are unable to continue to develop and produce competitive technology or deliver it to our clients in a timely and cost-competitive manner in the various markets we serve, it could adversely affect our financial condition, results of operations and cash flows.

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

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

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

The tools, techniques, methodologies, programs and components we use to provide our services may infringe upon the intellectual property rights of others. Infringement claims generally result in significant legal and other costs and may distract management from running our core 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.

9

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

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

Severe weather conditions may affect our operations.

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

Cybersecurity risks and threats could affect our business.

We rely heavily on information systems to conduct 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 impact on our systems when such incidents or attacks do occur.  If our systems for protecting against cybersecurity risks are circumvented or breached, this could result in the loss of our intellectual property or other proprietary information, including customer data, and disruption of our business operations.

Our ability to complete the proposed merger with Cameron is subject to various closing conditions and the receipt of consents and approvals from government entities which may impose conditions that could materially adversely affect Cameron or Schlumberger or cause the merger to be abandoned.

The merger agreement contains certain closing conditions, including approval of the proposed merger by Cameron stockholders, the absence of injunctions or other legal restrictions and that no material adverse effect shall have occurred with respect to either company. On December 17, 2015, Cameron stockholders voted to adopt our proposed merger.  Also, in November 2015 the U.S. Department of Justice cleared our proposed merger without any conditions.  However, we will be unable to complete the merger until consents and approvals are received from the European Commission and various other governmental entities.  Regulatory entities have broad discretion in administering the governing regulations and may impose certain requirements or obligations as conditions for their approval. The merger agreement may require us to accept conditions from these regulators that could adversely affect the combined company. If the regulatory clearances are not received, or they are not received on terms that satisfy the conditions set forth in the merger agreement, then we will not be obligated to complete the merger. We can provide no assurance that the various closing conditions will be satisfied and that the necessary approvals will be obtained, or that any required conditions will not materially adversely affect the combined company following the merger. In addition, we can provide no assurance that these conditions will not result in the abandonment or delay of the merger.

Failure to complete the proposed merger with Cameron could negatively impact our stock price and our future business and financial results.

If the proposed merger is not completed, our ongoing business may be adversely affected and we would be subject to several risks, including a decline in the market price of our common stock, negative customer perception and diversion of management’s focus on pursuing other opportunities that could be beneficial to us, in each case, without realizing any of the benefits that might have resulted had the merger been completed.

Multiple lawsuits have been filed against us and Cameron challenging the proposed merger, and an adverse ruling in any such lawsuit may prevent the merger from being completed.

After the announcement of the proposed merger, four putative class action lawsuits were commenced on behalf of stockholders of Cameron against Cameron and its directors, as well as against us and Schlumberger Holding Corporation and Rain Merger Sub (both of which are indirect wholly-owned subsidiaries).   These lawsuits were consolidated for all purposes and a consolidated amended class action complaint (the “Consolidated Complaint”) was filed. The Consolidated Complaint seeks various remedies, including enjoining the merger from being consummated, rescission of the merger to the extent already implemented and the plaintiffs’ costs and fees.  Additional lawsuits with similar allegations may be filed. While we believe these lawsuits are without merit and we intend to vigorously defend against such claims, the outcome of any such litigation is inherently uncertain.  One of the conditions to the closing of the merger is that no law, order, injunction, judgment, decree, ruling or other similar requirement shall be in effect that prohibits the completion of the merger. Accordingly, if any of the plaintiffs are successful in obtaining an injunction prohibiting the completion of the merger, then that injunction may prevent the merger from becoming effective, or delay its becoming effective.

We may fail to realize the anticipated benefits of the proposed merger.

The success of the proposed merger will depend on, among other things, our ability to combine our business with that of Cameron in a manner that facilitates growth opportunities and realizes anticipated synergies. However, we must successfully combine both businesses in a manner that permits these benefits to be realized. In addition, we must achieve the anticipated synergies without

10

adversely affecting current revenues and investments in future growth. If we are not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully, may take longer to realize than expected, or may never be realized.

Potential issues and difficulties we may encounter in the integration process include the following:

Business issues currently faced by Cameron may impact our operations.

To the extent that Cameron currently has or is perceived by customers to have operational challenges, such as on-time performance, safety issues or workforce issues, those challenges may raise concerns by our existing customers following the merger, which may limit or impede our future ability to obtain additional work from those customers.

Share Repurchases

On July 18, 2013, the Schlumberger Board of Directors (the “Board”) approved a $10 billion share repurchase program for Schlumberger common stock, to be completed at the latest by June 30, 2018.

Schlumberger’s common stock repurchase program activity for the three months ended December 31, 2015 was as follows:

In connection with the exercise of stock options under Schlumberger’s stock incentive plans, Schlumberger routinely receives shares of its common stock from optionholders in consideration of the exercise price of the stock options. Schlumberger does not view these transactions as requiring disclosure under this Item 5 as the number of shares of Schlumberger common stock received from optionholders is not material.

On January 21, 2016, the Board approved a new $10 billion share repurchase program for Schlumberger common stock.  This new program will take effect once the remaining $1.4 billion authorized to be repurchased under the July 18, 2013 program is exhausted.

Such forward-looking statements should be read in conjunction with our disclosures under “Item 1A. Risk Factors” of this Form 10-K.

Executive Overview

Schlumberger revenue of $35.5 billion in 2015 represented a drop of 27% from 2014 due to customer spending falling as commodity prices weakened during the year. Revenue in North America decreased 39%, driven by a land rig count that ended the year 68% lower than the peak seen in 2014 as well as by pricing pressure that intensified during the year. North American offshore revenue fell more modestly as rigs in the US Gulf of Mexico shifted from exploration to development work, although the overall market in North America was the weakest for oilfield services since 1986. Internationally, revenue declined 21% as customers cut budgets and pressured service pricing, with these effects often exacerbated by activity disruptions, project delays and cancellations.

In the oil markets, the negative sentiments that had dominated the year accelerated during the fourth quarter after some early optimism earlier in the summer. The impact of OPEC lifting production targets to produce at maximum rates, combined with production in North America from unconventional resources declining slower than expected following the April peak, has led to supply continuing to exceed increasing demand. As a result, commodity prices fell dramatically, with oil dropping to a 12-year low by the end of the year. These weaker fundamentals drove industry exploration and production (E&P) capital investment significantly lower, resulting in the first two-year sequential decline in spend in 30 years.

In the natural gas markets, US production grew to a record of 75 Bcf/d, as new fields in the US Gulf of Mexico were brought into production and supplies from unconventional shale gas and tight oil reservoirs continued to grow. This trend is expected to continue with newly completed pipeline capacity in the northeast United States bringing new supplies. A relatively mild start to the winter together with North American gas storage levels well above the five-year average will keep natural gas prices low. Internationally, European gas demand growth returned to positive territory.  Despite this increased demand, storage levels are at record highs due to ample supply from the North Sea and Russia, as well as from liquefied natural gas (LNG). Demand rebounded in Asia but remained in a downward trend overall. As LNG exports from Australia grow, the region is likely to remain oversupplied with low natural gas prices persisting.

Schlumberger’s financial performance in 2015 was significantly impacted by the large decrease in land activity, particularly in the US, where the year-end land rig count was less than 700 rigs. This created massive overcapacity in the land market that impacted pricing levels across a broad range of oilfield services. Internationally, revenue in the Europe, CIS & Africa Area fell by 26% as a result of the weakening Russian ruble, and due to a drop in exploration activities in the United Kingdom and Norway GeoMarkets. In Latin America, revenue declined 22% due to decreased activity in Mexico, Brazil, and Colombia as a result of sustained budget cuts that led to rig count reductions. Middle East & Asia Area revenue decreased 17% on lower activity in the Asia Pacific region, particularly in Australia, although this was partially offset by robust activity in the Gulf Cooperation Council countries, particularly Saudi Arabia, Kuwait, and Oman.

Among the Groups, Reservoir Characterization performance was negatively impacted by sustained cuts in exploration spending, currency weaknesses, and operational disruptions from exhausted customer budgets that affected Wireline activities, particularly in the Europe, CIS & Africa and Middle East & Asia Areas. In the Drilling Group, the drop in drilling activity coupled with persistent pricing pressure, currency weaknesses and operational disruptions lowered Drilling & Measurements and M-I SWACO revenues across all geographies but most significantly in the Europe, CIS & Africa Area. Production Group performance was mainly affected by the fall in North American land activity as exhausted customer budgets led to a continued decline in rig count and increased pricing pressure.

In this uncertain environment, Schlumberger continues to focus on what it can control.  Throughout the year, Schlumberger took a number of actions to streamline and resize its organization as it continues to navigate the current market downturn. In spite of current conditions, Schlumberger remains constructive in its view of the market outlook in the medium term, and continues to believe that the underlying balance of supply and demand will tighten, driven by growth in demand, weakening supply as the massive E&P investment cuts take effect, and by the size of the annual supply replacement challenge.

Fourth Quarter 2015 Results

Product Groups

Geographic Areas

Fourth-quarter revenue of $7.7 billion decreased $728 million, or 9%, sequentially with International revenue of $5.7 billion decreasing $354 million, or 6%, and North America revenue decreasing $318 million, or 14%.  Pricing pressure accounted for more than one-third of the overall sequential revenue decline, with the remainder attributable to a combination of lower activity levels and currency impacts.

Internationally, fourth-quarter revenue decreased 6% sequentially due to the combination of customer budget cuts, the start of the seasonal winter slow-down, persistent pricing pressure, currency weakness and the near absence of the usual year-end product, software, and multiclient seismic license sales.  Europe/CIS/Africa Area revenue decreased 9% sequentially mainly in Russia and

16

Central Asia due to weakness in the Russian ruble, the start of the seasonal winter slow-down in Russia as summer projects wound down, and activity reductions in the Caspian region.  Solid activity in the Nigeria & Gulf of Guinea and North Africa GeoMarkets was offset largely by lower activity in the UK, Central & West Africa and Angola GeoMarkets as rig count declined and projects ended.  Middle East & Asia Area revenue declined 5% sequentially mainly due to lower activity in Australia and the Asia-Pacific region as a result of customer budget cuts and project completions.  Revenue from the Middle East GeoMarkets was also lower as solid activity in Kuwait and Iraq was more than offset by reductions in the rest of the region due to the effects of service pricing concessions, project cancellations, delayed start-ups of new projects, and abrupt activity disruptions as budgets were exhausted. Latin America Area revenue decreased 1% sequentially, mainly on significantly lower activity in the Colombia & Peru, Brazil, and Argentina, Bolivia & Chile GeoMarkets due to customer budget cuts and currency weakness.  These effects were largely offset by multiclient seismic license sales in Mexico.

North America fourth-quarter revenue declined 14% sequentially, largely mirroring the US land rig count decline of 15% as customer cash flows diminished and E&P budgets were exhausted. Land revenue fell 18% from lower activity and persistent pricing pressure, while offshore revenue decreased 4%. The usual year-end surge in multiclient seismic license sales was largely muted.

Fourth-quarter pretax operating income of $1.3 billion decreased $233 million, or 15%, sequentially with International pretax operating income of $1.26 billion decreasing 13%, and North America pretax operating income decreasing 31%.

Fourth-quarter 2015 pretax operating margin of 16.6% decreased 132 basis points (bps) sequentially.  Internationally, pretax operating margin of 22.0% decreased 170 bps sequentially as pricing pressure across the Areas was partially offset by streamlining the cost and resource base.  In addition, project cancellations, delayed start-ups of new projects, and abrupt activity disruptions all contributed to the sequential reduction in pretax operating margin, particularly in the Middle East & Asia Area.  Middle East & Asia pretax operating margin decreased 448 bps to 22.5%, Europe/CIS/Africa fell 138 bps to 20.8%, while Latin America increased 229 bps to 23.0% mainly due to strong margins from multiclient seismic license sales in Mexico and Central America.  North America pretax operating margin declined 175 bps 7.1% as a result of pricing pressure that impacted all services and products.

Reservoir Characterization Group

Fourth-quarter revenue of $2.2 billion declined 7% sequentially, primarily due to sustained cuts in exploration spending, the start of the seasonal winter slow-down, currency weakness, and operational disruptions from exhausted customer budgets that impacted Wireline activities, particularly in the Europe/CIS/Africa and Middle East & Asia Areas.  This decline was partially offset by marine seismic surveys and multiclient seismic license sales in Mexico.  Year-end product and software sales were largely muted.

Pretax operating margin of 24.2% declined 230 bps sequentially as the contribution of high-margin multiclient seismic sales was more than offset by a decline in high-margin Wireline services. 

Drilling Group

Fourth-quarter revenue of $3.0 billion decreased 8% sequentially, primarily from a drop in drilling activity, persistent pricing pressure, the start of the seasonal winter slow-down, currency weakness, and operational disruptions from exhausted customer budgets that impacted Drilling & Measurements and M-I SWACO revenues, mainly in the Europe/CIS/Africa and Middle East & Asia Areas.

Pretax operating margin of 16.7% contracted 173 bps sequentially as revenue declined on pricing weakness and abrupt operational disruptions.

Production Group

Fourth-quarter revenue of $2.7 billion decreased 10% sequentially with 80% of the decrease attributable to a further decline in North American land activity as exhausted customer budgets led to a further decline in rig count and increased pricing pressure. Market pricing for pressure pumping services dropped to even more unsustainable levels. 

Pretax operating margin of 11.3% increased 24 bps sequentially despite lower activity and increasing pricing weakness in pressure pumping services.  The decline in pressure pumping margin was largely offset by the combination of accretive margin contributions from Schlumberger Production Management projects in Latin America and higher net earnings from the OneSubsea joint venture.

Full-Year 2015 Results

Product Groups

Geographic Areas

Full-year 2015 revenue of $35.5 billion decreased $13.1 billion, or 27%, versus the same period last year with International revenue of $25.2 billion decreasing $6.9 billion, or 21%, and North America revenue of $9.8 billion decreasing $6.3 billion, or 39%.

Internationally, revenue decreased 21% year-on-year due to customer budget cuts and service pricing concessions as customers responded to lower commodity prices.  Revenue was also impacted by the fall of certain currencies against the US dollar, which accounted for more than one-third of the revenue decline.  Europe/CIS/Africa Area revenue decreased 26%, mainly due to the

18

weakness in the Russian ruble.  Exploration activities in the UK and Norway fell as customer spending decelerated.  In Sub-Saharan Africa, offshore rigs demobilized as exploration decreased.  In North Africa, work progressed slowly while Libya activity remained muted, as onshore operations were limited due to security concerns.  Revenue in the Latin America Area declined 22% due to significantly lower activity levels in Mexico, Brazil and Colombia because of sustained budget cuts that led to rig count reductions.  The impact of the devaluation of the Venezuela bolivar also affected the revenue decline in the Venezuela, Trinidad and Tobago GeoMarket.   Middle East & Asia Area revenue decreased 17% due to a double-digit drop in revenue in the Asia-Pacific region, particularly in Australia.  This decrease arose from reduced activity and pricing concessions, but was partially offset by robust activity in the Gulf Cooperation Council countries in the Middle East, particularly in Saudi Arabia, Kuwait and Oman.  Activity in Iraq continued to decline.

North America full-year 2015 revenue decreased 39% year-on-year mainly from land which was down 45%, while offshore decreased 17% compared to the same period of 2014. The decrease in land was driven by severe activity and pricing declines as customer spending was cut.  With the year-end US land rig count 68% lower than the 2014 peak, the massive over-capacity in the land services market offers no signs of pricing recovery in the short- to medium-term.  Offshore activity in the US Gulf of Mexico remained resilient, although revenue did decline as work shifted from exploration to development activities driven by customer budget cuts.

Full-year 2015 pretax operating income of $6.5 billion decreased $4.1 billion, or 38%, versus the same period last year with International pretax operating income of $6.0 billion decreasing 22% and North America pretax operating income of $1.0 billion decreasing 67%.

Full-year 2015 pretax operating margin of 18.4% decreased 342 bps compared to 2014.  Internationally, pretax operating margin of 23.6% decreased 29 bps year-on-year.  Middle East & Asia pretax operating margin decreased 67 bps to 26.9%, Latin America expanded 58 bps to 21.9%, and Europe/CIS/Africa declined 79 bps to 21.3%.  Despite the revenue decline from pricing concessions and an increasingly unfavorable shift in revenue mix from offshore exploration to development, pretax operating margins were essentially flat internationally as a result of proactive cost and resource management.  North America pretax operating margin declined 874 bps year-on-year to 10.2% on decreased pressure pumping activity and pricing weakness on land. 

Reservoir Characterization Group

Full-year 2015 revenue of $9.5 billion was 26% lower than the same period last year primarily due to sustained customer cuts in exploration and discretionary spending that impacted Wireline and Testing Technologies and software sales.  Revenue also decreased due to lower WesternGeco marine vessel utilization and reduced multiclient sales.

Year-on-year, pretax operating margin decreased 294 bps to 25.8% as a result of an unfavorable overall revenue mix reflecting the decline in high-margin exploration activity as well as lower high-margin multiclient and software sales.

Drilling Group

Full-year 2015 revenue of $13.6 billion was 25% lower than the previous year primarily due to the severe drop in rig count in North America, reduced activity levels and service pricing concessions internationally that mainly affected Drilling & Measurements and M-I SWACO technologies. Unfavorable currency effects in Russia and Venezuela also contributed to the decline.

Year-on-year, pretax operating margin decreased 228 bps to 18.7%, primarily due to a decrease in higher-margin activities of Drilling & Measurements as well as pricing concessions.  Despite the revenue decline, prompt action on cost management and the benefit of a local cost structure that minimized the impact of unfavorable currency effects on pretax operating income helped limit the operating margin decline.

Production Group

Full-year 2015 revenue of $12.5 billion decreased 29% year-on-year, with approximately two-thirds of the decline attributable to Well Services pressure pumping technologies as a result of activity reductions and pricing pressure as the land rig count declined dramatically in North America.

Year-on-year, pretax operating margin declined 535 bps to 12.6% as lower activity and increasing pricing pressure continued in North America land.

Full-Year 2014 Results

Product Groups

Geographic Areas

Full-year 2014 revenue of $48.6 billion grew $3.3 billion, or 7%, versus the same period last year with International revenue of $32.1 billion increasing $1.2 billion, or 4%, and North America revenue of $16.2 billion growing $2.3 billion, or 16%.

Internationally, higher activities in a number of GeoMarkets, both offshore and in key land markets, contributed to the increase.  The increase was led by the Middle East & Asia, which increased 10%, mainly from robust drilling and exploration results in Saudi Arabia, Australia, the United Arab Emirates and Oman.  Europe/CIS/Africa increased 1%, led by the Sub-Saharan Africa region on strong

20

development and exploration activities, particularly in Central West Africa, Angola and Continental Europe GeoMarkets.  Norway also experienced strong growth driven by market share gains and higher rig-related services for a number of customers.  Latin America, however, decreased 1% primarily because of lower activity and pricing in Brazil and Mexico which was partially offset by strong activity in Argentina and Ecuador.

North America revenue increased 16% mainly due to land, which was up 22%, while offshore was down 3%.  The increase in land was driven by market share gains in pressure pumping, artificial lift and drilling services.   The pressure pumping growth was augmented by improvements in operational efficiency and the introduction of new technologies.  The decrease in offshore revenue was attributable to lower drilling and exploration activities, and due to a series of operational delays that impacted several product lines earlier in the year combined with lower multiclient sales.  

Full-year 2014 pretax operating income of $10.6 billion grew $1.2 billion, or 13%, versus the same period last year with International pretax operating income of $7.7 billion increasing 12% and North America pretax operating income of $3.1 billion increasing 12%.

Full-year 2014 pretax operating margin of 21.8% increased 113 bps compared to 2013, as pretax operating margins internationally were up 168 bps, to 23.9%, while North America pretax operating margin was down 75 bps, to 18.9%.  The increase in International Area margins reflected increased high-margin exploration activities, market share gains, growth in accretive integration-related activities and premium pricing on new technology introductions.  The North America margin contraction reflected pressure pumping commodity inflation.

Reservoir Characterization Group

Full-year 2014 revenue of $12.9 billion was down 1% compared to 2013.  Revenue increased in Testing Services, from higher offshore exploration, and Software Integrated Solutions, driven by software sales across all international areas.  However, these increases were offset by lower WesternGeco marine vessel utilization and reduced multiclient seismic sales.

Year-on-year, pretax operating margin increased 30 bps, to 28.7%, largely due to the higher-margin exploration activities that benefited Wireline Technologies and Testing Services.  Higher margin software sales also contributed to the improvement.   These increases were partially offset by lower profitability in WesternGeco due to lower vessel utilization and multiclient seismic sales.

Drilling Group

Full-year 2014 revenue of $18.1 billion was 8% higher than 2013, primarily due to the robust demand for Drilling & Measurements services and M-I SWACO Technologies as activity strengthened in the North America and Middle East & Asia Areas.  Land Rig revenue from the May 2014 acquisition of Saxon also contributed to the growth.

Year-on-year, pretax operating margin increased 171 bps, to 21.0%, primarily due to the increase in higher-margin exploration activities of Drilling & Measurements in North America offshore and in the international markets.  Improved profitability on Integrated Drilling Services activities also contributed to the margin increase.

Production Group

Full-year 2014 revenue of $17.8 billion increased 14% compared to 2013, primarily from Well Services pressure pumping technologies driven by market share gains, improvements in operational efficiency and the introduction of new technologies.  Schlumberger Production Management (SPM) revenue grew as projects in Latin America continued to progress ahead of work plans.  Revenue from the expanding artificial lift business also contributed to the year-on-year growth.  

Year-on-year, pretax operating margin increased 121 bps, to 18.0%, mainly on improved profitability for Well Services and Well Intervention, particularly internationally.  SPM activities also contributed to the margin expansion.  However, these improvements were partially offset by the decrease in margins in North America due to pressure pumping commodity cost inflation.

Interest and Other Income

Interest and other income consisted of the following:

The decrease in earnings of equity method investments in 2015 as compared to 2014 primarily reflects the effects of the downturn in the oil and gas industry, which has negatively impacted the majority of Schlumberger’s investments in affiliates, particularly those in North America.

The increase in earnings of equity method investments in 2014 as compared to 2013 primarily reflects the strong performance of a drilling service company in which Schlumberger has an investment, as well as the impact of the first full year of results from the OneSubsea joint venture.

Interest Expense

Interest expense of $346 million in 2015 decreased by $23 million compared to 2014 primarily as the effect of an increase in the weighted average debt balance of approximately $0.5 billion was more than offset by a 30 bps decrease in the weighted average borrowing rates from 2.8% in 2014 to 2.5% in 2015.

Interest expense of $369 million in 2014 decreased by $22 million compared to 2013 primarily as the effect of an increase in the weighted average debt balance of approximately $1.1 billion was more than offset by a 40 bps decrease in the weighted average borrowing rates from 3.2% in 2013 to 2.8% in 2014.

Other

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

Income Taxes

The Schlumberger effective tax rate was 25.9% in 2015, 25.2% in 2014, and 21.3% in 2013.

The Schlumberger effective tax rate is sensitive to the geographic mix of earnings. When the percentage of pretax earnings generated outside of North America increases, the Schlumberger effective tax rate will generally decrease. Conversely, when the percentage of pretax earnings generated outside of North America decreases, the Schlumberger effective tax rate will generally increase.

The effective tax rate for each of 2015, 2014 and 2013 was significantly impacted by the charges and credits described in Note 3 to the Consolidated Financial Statements because they were only partially tax effective.  Excluding the impact of these charges and credits, the effective tax rate was 20.2% in 2015, 21.9% in 2014 and 22.9% in 2013.  The decrease in the effective tax rate, excluding the impact of charges and credits, was primarily attributable to the change in the geographic mix of earnings and the favorable resolution of tax examinations in certain jurisdictions.  

Charges and Credits

Schlumberger recorded significant charges and credits in continuing operations during 2015, 2014 and 2013. These charges and credits, which are summarized below, are more fully described in Note 3 to the Consolidated Financial Statements.
