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, the Company today provides the industry’s widest range of products and services from exploration through production. As of December 31, 2010, the Company employed approximately 108,000 people of over 140 nationalities operating in approximately 80 countries. Schlumberger has principal executive offices in Paris, Houston and The Hague.
On August 27, 2010, Schlumberger acquired all of the outstanding shares of Smith International, Inc. (“Smith”), a leading supplier of premium products and services to the oil and gas exploration and production industry. In connection with this transaction, Schlumberger issued 176 million shares of its common stock, valued at approximately $9.8 billion as of the acquisition date. As a result of this transaction, Schlumberger consists of five business segments as of December 31, 2010 – Schlumberger Oilfield Services, WesternGeco, M-I SWACO, Smith Oilfield and Distribution.
 
Schlumberger Oilfield Services operates in each of the major oilfield service markets, managing its business through its GeoMarket* regions, which are grouped into four geographic areas: North America, Latin America, Europe/CIS/Africa and Middle East & Asia. 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. Within this business structure, Schlumberger Oilfield Services products and services are developed by a number of technology-based product lines, or Technologies, to capitalize on technical synergies. These products and services cover the entire life cycle of the reservoir and correspond to a number of markets in which Schlumberger Oilfield Services holds leading positions. The Technologies are also responsible for overseeing operational processes, resource allocation, personnel and quality in the GeoMarkets.
 
The Technologies are:
 
  •  Wireline – provides the information necessary to evaluate the subsurface formation rocks and fluids to plan and monitor well construction, and to monitor and evaluate well production. Wireline offers both open-hole and cased-hole services as well as a range of well remediation services.
 
  •  Drilling & Measurements – supplies engineering support, directional-drilling, measurement-while-drilling and logging-while-drilling services for all well profiles.
 
  •  Testing Services – provides exploration and production pressure and flow-rate measurement services both at the surface and downhole. The Technology also provides tubing-conveyed perforating services.
 
  •  Well Services – provides services used during oil and gas well drilling and completion as well as those used to maintain optimal production throughout the life of a well. The services include pressure pumping, well cementing and stimulation operations as well as intervention activities. The Technology also develops coiled-tubing equipment and services.
 
  •  Completions – supplies well completion services and equipment that includes upper and lower completion systems, sand management systems and permanently installed instrumentation for all types of well completion.
 
  •  Artificial Lift – provides electrical submersible pumps and gas lift equipment together with associated instrumentation, engineering and production optimization services.
 
  •  Data & Consulting Services – supplies interpretation and integration of all exploration and production data types, as well as expert consulting services for reservoir characterization, production enhancement, field development planning and multi-disciplinary reservoir and production solutions.

Part I, Item 1
 
 
  •  Schlumberger Information Solutions (SIS) – provides consulting, software, information management and IT infrastructure services that support core oil and gas industry operational processes.
 
  •  Geoservices – supplies mud logging services for geological and drilling surveillance. Geological surveillance includes formation evaluation to provide information on lithology and hydrocarbons encountered while drilling. Drilling surveillance enhances safety and optimizes drilling efficiency using a range of drilling parameter measurements. Geoservices also supplies slickline services for downhole mechanical well intervention and reservoir monitoring and downhole data acquisition.
 
Supporting the Technologies are various 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 Oilfield Services also offers customers its services through a business model known as Integrated Project Management (IPM). IPM combines the required services and products of the Technologies with drilling rig management expertise and project management skills to provide a complete solution to well construction and production improvement. IPM projects are typically of multi-year duration and include start-up costs and significant third-party components which cover services that Schlumberger does not provide directly. Projects may be fixed price in nature, contain penalties for non-performance and may also offer opportunities for bonus payments where performance exceeds agreed targets. IPM also provides specialized engineering and project management expertise when Schlumberger is requested to include these capabilities with services and products across the Technologies in a single contract. In no circumstances do IPM projects fail to respect the Schlumberger business profile that precludes any stake in the ownership of oil or gas reserves.
Schlumberger Oilfield Services 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 varies 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 wireline logging, well testing, measurement-while-drilling, logging-while-drilling and directional-drilling services, as well as fully computerized logging and geoscience software and computing services. A large proportion of Schlumberger offerings is non-rig related; consequently, revenue does not necessarily correlate to rig count fluctuations.
 
WesternGeco, the world’s most technologically advanced surface seismic company, provides comprehensive reservoir imaging, monitoring and development services with the most extensive seismic crews and data processing centers in the industry as well as a leading multiclient seismic library. Services range from 3D and time-lapse (4D) seismic surveys to multi-component surveys for delineating prospects and reservoir management. WesternGeco benefits from full access to the Schlumberger research, development and technology organization and shares similar business risks, opportunities for growth, principal methods of competition and means of marketing as Schlumberger Oilfield Services. Seismic solutions include proprietary single-sensor technologies for enhanced reservoir description, characterization and monitoring throughout the life of the field – from exploration through enhanced recovery. Other WesternGeco solutions include development of controlled-source electromagnetic and magneto-telluric surveys and their integration with seismic data.

Part I, Item 1A
 
Item 1A.    Risk Factors.
 
The following discussion of risk factors contains “forward-looking statements,” which are discussed immediately following Item 7A. of this Form 10-K. These risk factors may be important to understanding any statement in this Form 10-K or elsewhere. The following information should 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 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. A substantial or an extended decline in oil and gas prices could result in lower expenditures by the oil and gas industry, which 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. Declines, as well as anticipated declines, in oil and gas prices could also result in project modifications, delays or cancellations, general business disruptions, and delays in, or nonpayment of, amounts that are owed to us. These effects could have a material adverse effect on our results of operations and cash flows.
The prices for oil and natural gas have historically been volatile and may be affected by a variety of factors, including:
 
  •  demand for hydrocarbons, which is affected by worldwide population growth, economic growth rates and general economic and business conditions;
 
  •  the ability of the Organization of Petroleum Exporting Countries (“OPEC”) to set and maintain production levels for oil;
 
  •  oil and gas production by non-OPEC countries;
 
  •  the level of excess production capacity;
 
  •  political and economic uncertainty and sociopolitical unrest;
 
  •  the level of worldwide oil and gas exploration and production activity;
 
  •  the cost 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 oilfield services and downward pressure on the prices we charge. A significant downturn in the oil and gas industry could result in a reduction in demand for oilfield services and could adversely affect our financial condition, results of operations and cash flows.

Part I, Item 1A
 
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 80 countries in which we operate.
 
Our non-United States operations accounted for approximately 76% of our consolidated revenue in 2010, 84% in 2009 and 78% in 2008. Operations in countries other than the United States are subject to various risks, including:
 
  •  unsettled political and economic conditions in certain areas;
 
  •  exposure to possible 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 restrictions or embargoes imposed by the United States or other countries;
 
  •  restrictions under the United States Foreign Corrupt Practices Act or similar legislation in other countries;
 
  •  restrictions on the repatriation of income or capital;
 
  •  currency exchange controls;
 
  •  inflation; and
 
  •  currency exchange rate fluctuations and devaluations.
 
In addition, we are subject to risks associated with our operations in countries, including Iran, Syria, Sudan and Cuba, that are subject to trade and economic sanctions or other restrictions imposed by the United States or other governments or organizations. United States law enforcement authorities are currently conducting a grand jury investigation and an associated regulatory inquiry related to our operations in certain of these countries. Additionally, in 2009 prior to its merger with Schlumberger, Smith received an administrative subpoena with respect to its historical business practices in certain countries that are subject to United States trade and economic sanctions. If any of the risks described above materialize, or if any governmental investigation results in criminal or civil penalties or other remedial measures, it could reduce our earnings and our cash available for operations.
We are also subject to risks related to investment in our common stock in connection with certain US state divestment or investment limitation legislation applicable to companies with operations in these countries, and similar actions by some private investors, which could adversely affect the market price of our common stock.
 
Our merger with Smith will continue to be dilutive to our earnings per share in the near term, which may negatively affect the market price of our common stock.
 
Our merger with Smith will continue to be dilutive to earnings per share in the near term. Future events and conditions could decrease or delay any accretion, result in dilution or cause greater dilution than is currently expected, including adverse changes in:
 
  •  energy market conditions;
 
  •  commodity prices for oil, natural gas and natural gas liquids;
 
  •  production levels;
 
  •  reserve levels;
 
  •  operating results;
 
  •  competitive conditions;
 
  •  laws and regulations affecting the energy business;
 
  •  capital expenditure obligations; and
 
  •  general economic conditions.

Part I, Item 1A
 
 
Any dilution of, or decrease or delay of any accretion to, our earnings per share could cause the price of our common stock to decline.
 
Our offshore oil and gas operations could be adversely impacted by the Deepwater Horizon drilling rig accident and resulting oil spill; changes in and compliance with restrictions or regulations on offshore drilling in the US Gulf of Mexico and in other areas around the world may adversely affect our business and operating results.
 
On April 20, 2010, a fire and explosion occurred onboard the semisubmersible drilling rig Deepwater Horizon, owned by Transocean Ltd. and under contract to a subsidiary of BP plc. As a result of the incident and related oil spill, the Secretary of the US Department of the Interior directed the Bureau of Ocean Energy Management, Regulation and Enforcement (“BOEMRE”) to issue a suspension, until November 30, 2010, of drilling activities for specified drilling configurations and technologies. Although this moratorium was lifted on October 12, 2010, effective immediately, we cannot predict with certainty when drilling operations will fully resume in the US Gulf of Mexico. The BOEMRE has also issued new guidelines and regulations regarding safety, environmental matters, drilling equipment and decommissioning applicable to drilling in the US Gulf of Mexico, and may take other additional steps that could increase the costs of exploration and production, reduce the area of operations and result in permitting delays.
At this time, we cannot predict with any certainty what further impact, if any, the Deepwater Horizon incident may have on the regulation of offshore oil and gas exploration and development activity, or on the cost or availability of insurance coverage to cover the risks of such operations. Ongoing effects of and delays from the lifted suspension of drilling activity in the US Gulf of Mexico, or the enactment of new or stricter regulations in the United States and other countries where we operate, could materially adversely affect our financial condition, results of operations or 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 and explosives, environmental protection, including laws and regulations governing air emissions, 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 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 potentially material liabilities relating to the investigation and cleanup of 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 of new or increased liabilities that could reduce our earnings and our cash available for operations. We believe we are currently in substantial compliance with environmental laws and regulations.
 
We could be subject to substantial liability claims, which would adversely affect our financial condition, results of operations and cash flows.
 
Certain equipment used in the delivery of oilfield services, such as directional drilling equipment, perforating systems, subsea completion equipment, radioactive materials and explosives and well completion systems, are used in hostile environments, such as exploration, development and production applications. An accident or a failure of a product could cause personal injury, loss of life, damage to property, equipment or the environment, and 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, in the future we may not be able to maintain insurance at levels of risk coverage or policy limits that we deem adequate. Substantial claims made under our policies could cause our premiums to increase. Any future damages caused by our 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.
 
If we are unable to maintain technology leadership, this could adversely affect any competitive advantage we hold.
 
If we are unable to develop and produce competitive technology or deliver it to our clients in the form of service offerings 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.
 
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. 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. Additionally, developing non-infringing technologies would increase our costs.
 
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 until the platforms or structures have been repaired. Any of these events could adversely affect our financial condition, results of operations and cash flows.
 
Demand for our products and services could be reduced or eliminated by governmental regulation or a change in the law.
 
International, national, and state governments and agencies are currently evaluating and promulgating climate-related legislation and regulations that are focused on restricting greenhouse gas (“GHG”) emissions. In the United States, the Environmental Protection Agency (“EPA”) is taking steps to require monitoring and reporting of GHG emissions and to regulate GHGs as pollutants under the Clean Air Act (“CAA”). The EPA’s “Mandatory Reporting of Greenhouse Gases” rule established a comprehensive scheme of regulations that require monitoring and reporting of GHG emissions that began in 2010. Furthermore, the EPA recently proposed additional GHG reporting rules specifically for the oil and gas industry. The EPA has also published a final rule, the “Endangerment Finding,” finding that GHGs in the atmosphere endanger public health and welfare, and that emissions of GHGs from mobile sources cause or

contribute to the GHG pollution. Following issuance of the Endangerment Finding, the EPA promulgated final motor vehicle GHG emission standards on April 1, 2010. The EPA has asserted that the final motor vehicle GHG emission standards will trigger construction and operating permit requirements for stationary sources. In addition, climate change legislation is pending in the United States Congress. These developments may curtail production and demand for 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, which may in turn adversely affect future results of operations. Additionally, legislation to reduce greenhouse gases may have an adverse effect on our operations, including payment of additional costs due to carbon emissions. Higher carbon emission activities include transportation, including marine vessels, cement production (by third party suppliers), and electricity generation (by third party suppliers) as well as other activities. Finally, our business could be negatively affected by climate change related physical changes or changes in weather patterns, which could result in damages to or loss of our physical assets, impacts to our ability to conduct operations and/or disruption of our customers’ operations.
Legislation may be introduced in the United States Congress that would authorize the EPA to regulate hydraulic fracturing. In addition, a number of states are evaluating the adoption of legislation or regulations governing hydraulic fracturing. Such legislation or regulations could reduce demand for pressure pumping services. If federal and/or state legislation or regulations were enacted, it could adversely affect our financial condition, results of operations and cash flows. We are unable to predict whether the proposed legislation, regulations, or any other proposals will ultimately be enacted.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations.
 
The following discussion and analysis contains forward-looking statements, including, without limitation, statements relating to our plans, strategies, objectives, expectations, intentions and resources. Such forward-looking statements should be read in conjunction with our disclosures under “Item 1A. Risk Factors” of this Report.
 
Executive Overview
 
After two consecutive years of falling oil demand in 2008 and 2009 induced by the global economic recession, a strong recovery occurred in 2010. Consumption averaged 87.7 million barrels per day, including an all-time peak of over 89 million barrels per day in December, and made the year-on-year increase the second largest in three decades. Oil prices remained in the range of $65-$85 per barrel for much of 2010, but recorded a spike above $90 at the end of the year. The major demand forecasts released during 2010 have continued to increase as a result of the improving economic outlook – particularly in the developing economies. On the supply side, the adherence to production quota by the OPEC countries helped keep the market balanced, although such adherence diminished slightly as the year progressed. Strength in non-OPEC production, improvement in new project developments following the investment cuts in 2009, and lower production costs helped provide additional assurance to the markets.
Natural gas markets behaved differently. Decreasing gas demand during the recession, increasing unconventional gas production in North America, and the commissioning of a number of new large liquefied natural gas export facilities around the world led to an over-supplied market with consequent pressure on spot prices. Within the United States – the world’s largest natural gas market – natural gas storage levels have remained significantly above the five-year range since March 2010 despite lower volumes of Canadian gas imports and some power generation fuel switching from coal to gas. With natural gas price forecasts from the Energy Information Agency for 2011 slipping by nearly a third compared to initial projections made at the beginning of the year, an increasing portion of the drilling and completion activity in shale reservoirs has shifted to liquid and condensate-rich plays in North America.
Within this market, Schlumberger Oilfield Services full-year revenue in 2010 of $22.08 billion grew 8% versus 2009, driven by recovery in the North America natural gas market through increasing demand and stronger pricing for pressure pumping services. The North America Area also benefited from greater activity in liquids-rich plays in a number of basins. Offshore, the tragic Macondo accident in the US Gulf of Mexico led to a shutdown in deepwater operations that severely impacted US offshore activity and led to slowdowns in other parts of the world, although these were being absorbed as the fourth quarter developed. The Middle East and Asia Area revenue climbed 7% from a number of factors including increasing wireline logging and expanded IPM work. Latin America revenue grew by 2%, with rapid growth in Brazil overcoming weaker activity in Mexico as poor weather, increasing security concerns and reduced client budgets impacted operations. Europe/CIS/Africa revenue decreased 4% versus 2009. Among the Technologies, growth was primarily seen in Well Services activities, both in volume and in price although the acquisition of Geoservices also contributed to the increase.
In addition to growing activity, results were underpinned through continuing market penetration of new-technology services such as Scope* advanced logging-while-drilling measurements, Scanner* wireline technologies, and ACTive* coiled-tubing services. Scanner services were boosted by the commercial introduction of the latest family member, the Dielectric Scanner* tool, which was unveiled during the year. As a unique industry service capable of measuring saturation in a variety of reservoir applications, the service completed a two-year pilot project in Saudi Arabia targeted at reservoir monitoring, where 35 logs were recorded in various fields, both on land and offshore, to assess water flooding sweep efficiency as an aid to field development planning.
In reservoir production, ACTive real-time coiled tubing services saw growth, particularly with ACTive conveyance of Wireline Flow Scanner* production logging technology, and with fiber-optic continuous measurements of temperature and pressure along the well bore. Growing deployment of integrated technologies such as these confirms exciting growth possibilities across the Schlumberger technology portfolio particularly in horizontal and extended-reach wells.
It was however drilling services that displayed early evidence of the opportunities provided by the acquisitions of Geoservices and Smith International that were announced during the first quarter. These successes included the completion of a remote three-well exploration project offshore Greenland that used Schlumberger technologies combined with Smith and M-I SWACO products and services as well as Geoservices mud logging. In Brazil, a similar combination of services helped one well record substantial increases in rates of penetration, while meeting all

directional drilling goals. In this particular case the integrated nature of the bottomhole assembly demonstrated how technology optimization can impact performance in the high-cost deepwater drilling environment. A third such operation offshore Indonesia further displayed the value of integrated bottomhole assemblies.
WesternGeco revenue of $1.99 billion in 2010 was 6% lower than 2009 primarily as a result of lower Marine activity and weaker pricing. While Land activity was also weaker, strong Multiclient sales, particularly in the fourth quarter, were able to offset some of these effects. New seismic technology scored some significant successes with penetration of marine single-vessel, full-azimuth coil shooting surveys into a number of the major offshore basins around the world. Coil shooting, unique to Schlumberger, brings better illumination of complex pre-salt, sub-salt and sub-basalt formations in a variety of environments.
The integration of Geoservices and Smith International proceeded smoothly during the year. The complementary nature of many of the product and service lines concerned helped the process while a network of integration teams and Area coordinators rapidly identified revenue and cost-synergy opportunities that contributed to results in 2010 and that augur well for 2011. Total Schlumberger 2010 results reflect four months activity from the acquired Smith businesses, which contributed revenue of $3.30 billion.
In a related move, Schlumberger signed a letter of intent with Eurasia to swap certain assets in Russia to build critical mass in drilling services. Under the terms of this agreement, Eurasia will acquire a number of Schlumberger-owned drilling rigs, while Schlumberger will acquire a range of Eurasia service assets including directional drilling, measurement-while-drilling, well cementing and drilling fluids. Further, both companies agreed to enter a strategic alliance upon completion of the transaction whereby Schlumberger will become the preferred supplier of drilling services to Eurasia Drilling for up to 200 rigs for a 5-year period. This agreement not only increases the market for our services across the rig fleet of the largest Russian drilling company, it also encourages the development of fit-for-purpose bottom-hole assembly technology development as drilling intensity increases in Russia in order to sustain hydrocarbon production.
Two years ago we began a program called “Excellence in Execution”. This was designed to create a step change in our service quality and efficiency and, in deepwater, was aimed at enabling clients to reduce the risk and cost of their deepwater operations. The program, in addition to equipment and procedural improvements, provides for competency certification of all personnel involved in deepwater operations. We have been encouraged by the initial results of this multiyear initiative, as well as by our customers’ acceptance of it. While additional control and oversight will undoubtedly add cost, this will be offset in the long run by improvements in operating procedures and technology. We therefore welcome current efforts to better understand and control the risks associated with deepwater operations.
For 2011, economic projections for world real GDP growth are converging towards a median estimate of 4.2%, slightly lower than the 2010 level, and still with a significant level of uncertainty. A large gap exists between GDP growth rates of Organization for Economic Cooperation and Development (OECD) and non-OECD countries – particularly in China and in other developing Asian economies. However there is remarkable agreement on various oil demand forecasts for 2011, which all lie within 1.4 million barrels per day of each other.
As we look forward to 2011 it is therefore important to remember that the primary driver of our business has always been, and will remain, the demand for oil and gas. Oil prices have moved into a range that will encourage increased investment, particularly in exploration, which remains the swing factor in operators’ budgets. While we do not anticipate any substantial recovery in deepwater US Gulf of Mexico, we do expect a marked increase in deepwater activity in the rest of the world. These factors, coupled with increases in development activity and production enhancement in many other areas, promise stronger growth rates as the year unfolds.
For natural gas, activity in the United States is likely to remain strong – at least through the first half of the year – due to the commitments necessary to retain leases, the backlog of wells to be completed, and the contribution of natural gas liquids to overall project economics. Increased service capacity, however, will negatively affect pricing at some stage during the year.
Overseas, the governing factor on gas activity, particularly in the Middle East, will be the ability of many nations to use gas as a substitute for oil to meet increased local energy demand, thus freeing up more liquids for export. Elsewhere the long lead time necessary to execute large gas projects for LNG exports will ensure that a certain level of activity is maintained.
Unconventional gas resources will continue to attract considerable interest outside North America. The leading activity will continue to be in conventional gas in tight, or low permeability, reservoirs, and in coal-bed methane

developments. There will be exploration activity around the potential that shale gas offers in many other parts of the world.
Increased activity coupled with the greater technology needs of higher exploration, deepwater, and tight gas activity – particularly outside North America – will make 2011 a stronger year for Schlumberger. The importance of risk reduction and the minimization of drilling cost make the acquisitions of Geoservices and Smith major contributors to our future growth in this scenario.

Oilfield Services
 
Fourth-quarter revenue of $6.01 billion increased 9% sequentially. Sequentially, North America Area revenue increased 27% on strong activity on land in the US and Canada as well as from the early payout of an IPM gain share project. In the Middle East & Asia Area, revenue grew on year-end equipment, Schlumberger Information Solutions (SIS) software sales, and on higher activity in the Iraq, East Asia and Indonesia GeoMarkets. Europe/CIS/Africa Area revenue increased from stronger activity in the North Sea, West & South Africa, Caspian and Continental Europe GeoMarkets, as well as from year-end SIS software sales. These increases were partially offset by a decrease in Latin America Area revenue primarily due to continuing weakness in the Mexico/Central America GeoMarket.
All Technologies recorded sequential growth, most notably Well Services due to continuing strong activity in North America, and SIS and Artificial Lift from year-end sales. IPM revenue also increased as a result of the early payout on the IPM project in North America.

Part II, Item 7
 
Fourth-quarter pretax operating income of $1.33 billion increased 21% sequentially. Pretax operating margin increased 224 bps sequentially to 22.1% primarily driven by the robust performance in North America and strong contributions from the year-end equipment and software sales.
 
North America
 
Fourth-quarter revenue of $1.60 billion increased 27% sequentially and pretax operating income of $385 million was 75% higher.
Sequentially, revenue in US land grew 24% versus a 4% increase in rig count due to a combination of additional service capacity, improved utilization, and high service intensity that mostly benefited Well Services technologies. Canada revenue grew from higher land activity for Well Services, although this was partially offset by a slowdown in offshore activity that impacted Drilling & Measurements services. The US Gulf of Mexico revenue increased through a modest improvement in shelf activity and from Completion Systems equipment sales. An $87 million early payout relating to services on an IPM gain share project – triggered by the customer’s sale of the field – also contributed to Area growth.
Pretax operating margin for the Area increased 658 bps sequentially to 24.0%. This increase was largely driven by US land through stronger activity and increased efficiency for Well Services operations. The IPM gain share payout contributed approximately $55 million to Area pretax operating income.
 
Latin America
 
Fourth-quarter revenue of $1.05 billion decreased 2% versus the prior quarter. Pretax operating income of $174 million increased 9% compared to the third quarter of 2010.
Sequentially, the Brazil GeoMarket achieved record high revenue on strong deepwater activity, while revenue in the Peru/Colombia/Ecuador GeoMarket grew from higher gain share on IPM activity in Colombia and from Testing Services equipment sales in Peru. These increases, however, were insufficient to offset a significant revenue drop in the Mexico/Central America GeoMarket where continuing security issues and client budgetary constraints further reduced IPM activity levels.
Pretax operating margin improved 171 bps sequentially to 16.6% primarily due to a more favorable revenue mix in the Peru/Colombia/Ecuador and Venezuela/Trinidad & Tobago GeoMarkets.
 
Europe/CIS/Africa
 
Fourth-quarter revenue of $1.78 billion increased 3% compared to the third quarter of 2010. Pretax operating income of $339 million increased 7% sequentially.
Sequentially, revenue in the North Sea GeoMarket increased primarily from higher activity in Norway and from year-end SIS software sales. In the West & South Africa GeoMarket, revenue grew on stronger activity that benefited Wireline and Drilling & Measurements services and on higher Completion Systems equipment sales. Caspian GeoMarket revenue increased from the startup of several projects that resulted in higher demand for Drilling & Measurements, Testing Services and Wireline technologies as well as from a Well Services equipment sale. Continental Europe revenue grew on higher activity for Well Services and Testing Services technologies and on year-end SIS software sales. These increases, however, were partially offset by a decrease in Nigeria & Gulf of Guinea GeoMarket revenue from lower Completion Systems equipment sales and from delays that reduced demand for Wireline services. Russia revenue was also lower with the onset of the winter slowdown.
Pretax operating margin improved sequentially by 74 bps to 19.0% primarily from a stronger mix of high-margin Wireline and Drilling & Measurements services in the North Sea and West & South Africa GeoMarkets as well as from year-end SIS software sales across much of the Area. These increases were partially offset by the impact of the activity weakness in the Nigeria & Gulf of Guinea GeoMarket.
 
Middle East & Asia
 
Fourth-quarter revenue of $1.49 billion increased 6% sequentially. Pretax operating income of $434 million increased 2% sequentially.

Part II, Item 7
 
Sequentially, revenue growth resulted from the continued ramp up of IPM activity in Iraq and the start of new offshore projects in East Asia. Year-end sales of Artificial Lift and Completion Systems equipment, Well Services products, and SIS software also contributed to Area growth. These increases were partially offset by lower revenue in the Australia/Papua New Guinea GeoMarket resulting from offshore project completions and delays in land activity due to severe flooding, and by lower activity in the Qatar GeoMarket that reduced demand for Wireline and Drilling & Measurements services.
Pretax operating margin decreased 119 bps sequentially to 29.1% as the positive contribution from the year-end sales and a more favorable revenue mix in the Arabian GeoMarket were insufficient to offset the impact of the lower activity in the Australia/Papua New Guinea GeoMarket and startup costs in Iraq.
 
WesternGeco
 
Fourth-quarter revenue of $560 million increased 17% sequentially. Pretax operating income of $113 million increased 183% sequentially.
Sequentially, revenue growth was driven by Multiclient, which recorded strong year-end sales from the US Gulf of Mexico. This increase was partially offset by a decrease in Marine revenue due to the seasonal slow-down in activity. Land and Data Processing revenues were flat sequentially.
Pretax operating margin increased 11.8 percentage points sequentially to 20.2% as the result of the high Multiclient sales partially offset by the impact of the lower Marine activity.

Oilfield Services
 
Full-year 2010 revenue of $22.08 billion was 8% higher than 2009. Revenue growth was strongest in the North America Area mostly as a result of higher activity and pricing for Well Services technologies in US Land but partially offset by

reduced activity in the US Gulf of Mexico. Latin America revenue increased on strong activity in the Brazil and Peru/Ecuador/Colombia GeoMarkets partially offset by reduced IPM activity in Mexico/Central America due to client budgetary constraints. Middle East & Asia Area revenue grew from higher drilling activity in the Australia/Papua New Guinea, China/Japan/Korea and East Asia GeoMarkets as well as from increased IPM activity and strong demand for Well Services technologies in the Middle Eastern GeoMarkets. The addition of Geoservices also contributed to the increased revenue. These increases were partially offset by a decrease in Europe/CIS/Africa revenue as reduced activity in the North Africa, Libya, Caspian and Continental GeoMarkets and generally lower pricing across the Area offset higher activity in Russia.
Year-on-year, pretax operating margin declined 82 bps to 20.3% as a significant improvement in North America Area performance was insufficient to offset the reduced activity and weaker pricing in the Europe/CIS/Africa Area and lower IPM activity in Latin America.
 
North America
 
Revenue of $5.01 billion was 35% higher than last year primarily due to strong activity in unconventional oil and gas reservoirs, improved pricing in US Land for Well Services technologies and improved activity levels in oil basins in Canada. These increases were partially offset by a decrease in the US Gulf of Mexico revenue as a six-month moratorium on drilling and lingering uncertainty about rules for operating resulted in the stoppage of deepwater drilling activity.
Year-on-year, pretax operating margin increased 10 percentage points to 16.0% mostly due to the stronger activity and improved pricing in the US land, partially offset by the impact of the activity slow-down in the US Gulf of Mexico.
 
Latin America
 
Revenue of $4.32 billion was 2% higher than the previous year. Growth was strongest in the Brazil GeoMarket where higher offshore activity increased demand for Wireline and Drilling & Measurements services technologies. Revenue also increased significantly in the Peru/Ecuador/Colombia GeoMarket due to strong IPM activity and higher Artificial Lift systems sales. The addition of Geoservices also contributed to the growth. These increases were partially offset by a decrease in the Mexico/Central America GeoMarket revenue as client budgetary constraints reduced IPM activity.
Year-on-year, pretax operating margin decreased 110 bps to 16.7% primarily due to the reduced activity levels in Mexico/Central America partially offset by the impact of lower costs in Venezuela/Trinidad & Tobago.
 
Europe/CIS/Africa
 
Revenue of $6.88 billion was 4% lower year-on-year. This decrease was largely attributable to lower pricing across much of the Area and reduced activity in the North Africa, Libya, Caspian and Continental Europe GeoMarkets. These decreases were partially offset by increases in Russia due to higher IPM activity. The addition of Geoservices also contributed to Area revenue.
Year-on-year, pretax operating margin decreased 543 bps to 18.4% primarily due to the lower overall activity levels and reduced pricing.
 
Middle East & Asia
 
Revenue of $5.59 billion was 7% higher than the previous year primarily due to strong drilling activity in Asia, particularly in the Australia/Papua New Guinea, China/Japan/Korea and East Asia GeoMarkets, and to increased IPM activity and strong demand for Well Services technologies in the Middle Eastern GeoMarkets. The addition of Geoservices also increased Area revenue.
Year-on-year, pretax operating margin decreased 199 bps to 30.4% primarily due the impact of lower pricing across the Area.
 
WesternGeco
 
Full-year 2010 revenue of $1.99 billion was 6% lower than the prior year primarily due to reduced activity and pricing in Marine. This decrease was partially offset by an increase in Multiclient revenue as the result of increased acquisition and sales of wide-azimuth surveys in the US Gulf of Mexico.


22


Table of Contents

Part II, Item 7
 
Year-on-year, pretax operating margin decreased 194 bps to 13.4% as the result of the lower pricing and activity in Marine and reduced profitability in Land and Data Processing. These decreases were partially offset by an improvement in Multiclient margins on the increased activity.

Oilfield Services
 
Full-year 2009 revenue of $20.52 billion declined 16% versus 2008. Lower natural gas prices and unfavorable market fundamentals resulted in a 37% decline in North America revenue, primarily in the US Land and Canada GeoMarkets. Europe/CIS/Africa revenue decreased 13% mainly due to the weakening of local currencies against the US dollar and reduced activity in the Russia, North Sea, West & South Africa and Caspian GeoMarkets as well as in Framo, which was partially offset by increased activity in the North Africa GeoMarket. Middle East & Asia revenue also fell by 9% primarily due to decreases in the East Asia, East Mediterranean, Arabian and Australia/Papua New Guinea GeoMarkets. Latin America revenue was only marginally lower than last year as the impact of the weakening of local currencies against the US dollar and much lower activity in Venezuela/Trinidad & Tobago and Peru/Colombia/Ecuador were nearly offset by stronger activity in Mexico/Central America and Brazil. Weakening of local currencies against the US dollar reduced 2009 revenue by approximately 4%. Across the Areas, all of the Technologies recorded revenue declines except Testing Services. IPM recorded revenue growth compared to the same period last year.
Full-year 2009 pretax operating margin decreased 5.7 percentage points to 21.1%, on the significant drop in activity and pricing pressure experienced across all the Areas, but most notably in North America.
 
North America
 
Revenue of $3.71 billion was 37% lower than last year with reductions across the entire Area. The decreases were highest in US Land and Canada, where lower natural gas prices resulted in a steep drop in activity and consequent pressure on pricing. Canada revenue was also lower as the result of the weakening of the Canadian dollar against the US dollar. Revenue in the US Gulf of Mexico GeoMarket was severely impacted by weaker shelf drilling activity and strong pricing pressure.
 
Pretax operating margin fell 17.3 percentage points to 5.8% due to the significant decline in activity levels across the Area, combined with the severe pricing erosion.

Latin America
 
Revenue of $4.22 billion was marginally lower compared to 2008. The weakening of local currencies against the US dollar reduced 2009 revenue by approximately 3%. In addition, Venezuela/Trinidad & Tobago revenue fell due to significantly reduced customer spending while Peru/Colombia/Ecuador revenue was lower due to reduced gain share in IPM projects. These decreases were mostly offset by higher IPM activity in Mexico/Central America and increased offshore activity in Brazil.
Pretax operating margin decreased 245 bps to 17.8% primarily as the result of the sharp activity decline in Venezuela/Trinidad & Tobago and the lower gain share in Peru/Colombia/Ecuador.
 
Europe/CIS/Africa
 
Revenue of $7.15 billion was 13% lower than last year largely due to the weakening of local currencies against the US dollar, which reduced revenue by approximately 7%. In addition, revenue was negatively impacted by reduced customer spending that resulted in significantly lower activity and pricing erosion in Russia and the North Sea. Revenue in the West & South Africa and Caspian GeoMarkets and in Framo was also negatively impacted by lower activity levels. These decreases were partially offset by a revenue increase in the North Africa GeoMarket due to strong Testing Services product sales.
Pretax operating margins declined 357 bps to 23.9% on a combination of the overall lower activity and heavy pricing pressure across the Area.
 
Middle East & Asia
 
Revenue of $5.23 billion was 9% below 2008. Revenue was down across much of the Middle East, especially in the East Mediterranean and Arabian GeoMarkets, due to reduced demand for Drilling & Measurements, Wireline and Testing Services technologies. Revenue in Asia also fell, primarily due to a decrease in offshore exploration activity, which was most significant in the East Asia and Australia/Papua New Guinea GeoMarkets, resulting in lower demand for Testing Services and Wireline technologies as well as Completion Systems products.
Pretax operating margin decreased 268 bps to 32.4% primarily as a result of the lower overall activity and a less favorable revenue mix across the Area.
 
WesternGeco
 
Full-year revenue of $2.12 billion was 25% lower than 2008. Revenue decreased across all product lines, with the largest declines experienced in Marine and Multiclient. Marine revenue declined due to lower activity combined with reduced pricing as the result of weak market conditions. Multiclient revenue decreased primarily in North America, as customers continued to reduce discretionary spending. Land revenue fell on lower crew utilization, while Data Processing revenue was down reflecting lower activity primarily in Europe/Africa and in North America.
Pretax margin decreased 14.1 percentage points to 15.4% primarily due to the weaker Marine activity and pricing as well as lower Multiclient sales.

Interest Income
 
The average return on investments decreased to 1.2% in 2010 from 1.4% in 2009 and the weighted average investment balance of $4.0 billion in 2010 decreased $0.5 billion compared to 2009.
The average return on investments decreased to 1.4% in 2009 from 3.5% in 2008 and the weighted average investment balance of $4.5 billion in 2009 increased $1.1 billion compared to 2008.
 
Equity in Net Earnings of Affiliated Companies
 
Equity income from the M-I SWACO joint venture in 2010 represents eight months of equity income through the closing of the Smith transaction. The decrease in equity income relating to this joint venture from 2008 to 2009 was attributable to a significant decline in M-I SWACO activity levels, primarily in its United States and Europe/Africa regions, as well as increased pricing pressures.
 
Interest Expense
 
Interest expense of $207 million in 2010 decreased by $14 million compared to 2009 due to a decline in the weighted average borrowing rates, from 3.9% to 3.2%. The weighted average debt balance of $6.4 billion in 2010 increased $0.8 billion compared to 2009.
Interest expense of $221 million in 2009 decreased by $26 million compared to 2008 primarily due to a decline in the weighted average borrowing rates, from 4.5% to 3.9%.
 
Other
 
Gross margin was 21.7%, 24.0% and 30.2% in 2010, 2009 and 2008, respectively.
The decline in gross margin in 2010 compared to 2009 was primarily attributable to the inclusion of the acquired Smith businesses as well as pricing pressure for Oilfield Services, particularly in the Europe/CIS/Africa Area, partially offset by improved activity levels and pricing in the North America Area.
The decline in gross margin in 2009 compared to 2008 was primarily attributable to lower activity coupled with the impact of a significant reduction in pricing across all of Oilfield Services, most notably in North America and Europe/CIS/Africa. Weaker Marine activity and pricing and reduced Multiclient sales in WesternGeco also contributed to the margin decline.
Research & engineering and General & administrative expenses, as a percentage of Revenue, were as follows:
 
                         
    2010   2009   2008

Income Taxes
 
The Schlumberger effective tax rate was 17.3% in 2010, 19.6% in 2009, and 20.9% in 2008.
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.

Part II, Item 7
 
The effective tax rate for 2010 was significantly impacted by the charges and credits described in Note 3 to the Consolidated Financial Statements. The effective tax rate for 2009 was also impacted by charges, but to a much lesser extent. Excluding charges and credits, the effective tax rate in 2010 was approximately 20.6% compared to 19.2% in 2009. This increase is largely attributable to the geographic mix of earnings as well as the inclusion of four months results from the merger with Smith. Smith, which as a US company has a US tax rate applicable to its worldwide operations and as such, will serve to increase Schlumberger’s overall effective tax rate.
The decrease in the Schlumberger effective tax rate in 2009 as compared to 2008 was primarily attributable to the geographic mix of earnings. Schlumberger generated a lower proportion of its pretax earnings in North America in 2009 as compared to 2008. In addition, outside North America, various GeoMarkets with lower tax rates contributed a greater percentage to pretax earnings in 2009 as compared to 2008.
 
Charges and Credits
 
Schlumberger recorded significant charges and credits in continuing operations during 2010, 2009 and 2008. These charges and credits, which are summarized below, are more fully described in Note 3 to the Consolidated Financial Statements.

The premium paid in excess of the carrying value to repurchase the $1.275 billion of debt was approximately $67 million.
 
  •  During the first quarter of 2009, Schlumberger entered into a €3.0 billion Euro Medium Term Note program. This program provides for the issuance of various types of debt instruments such as fixed or floating rate notes in Euro, US dollar or other currencies.
 
Schlumberger issued €1.0 billion 2.75% Guaranteed Notes due 2015 in the fourth quarter of 2010 under this program. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US denominated debt on which Schlumberger will pay interest in US dollars at a rate of 2.56%. The proceeds from these notes will be used for general corporate purposes.
 
During the first quarter of 2009, Schlumberger issued €1.0 billion 4.50% Guaranteed Notes due 2014 under this program. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 4.95%. The proceeds from these notes were used to refinance existing debt obligations and for general corporate purposes.
 
  •  During the third quarter of 2009, Schlumberger issued $450 million of 3.00% Guaranteed Notes due 2013. The proceeds from these notes were used to refinance existing debt obligations.
 
  •  In September 2008, Schlumberger issued €500 million 5.25% Guaranteed Notes due 2013. Schlumberger entered into agreements to swap these Euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 4.74%. The proceeds from these notes were used to repay commercial paper borrowings.
 
  •  On April 20, 2006, the Schlumberger Board of Directors approved a share repurchase program of up to 40 million shares of common stock to be acquired in the open market before April 2010, subject to market conditions. This program was completed during the second quarter of 2008.
 
On April 17, 2008, the Schlumberger Board of Directors approved an $8 billion share repurchase program for shares of Schlumberger common stock, to be acquired in the open market before December 31, 2011, of which $3.15 billion had been repurchased as of December 31, 2010.
 
The following table summarizes the activity under these share repurchase programs during 2010, 2009 and 2008:

  income experienced in 2009 and the significant pension plan contributions made during 2009, offset by an improvement in working capital requirements.
 
At times in recent periods, Schlumberger has experienced delays in payments from certain of its customers. Schlumberger operates in approximately 80 countries. At December 31, 2010, only three of those countries individually accounted for greater than 5% of Schlumberger’s accounts receivable balance of which only one, the United States, represented greater than 10%.
 
  •  Dividends paid during 2010, 2009 and 2008 were $1.04 billion, $1.01 billion and $0.96 billion, respectively.
 
In January 2011, Schlumberger announced that its Board of Directors had approved an increase in the quarterly dividend of 19%, to $0.25.
 
  •  Capital expenditures were $2.9 billion in 2010, $2.4 billion in 2009 and $3.7 billion in 2008. Capital expenditures in 2008 reflected the record activity levels experienced in that year. The decrease in capital expenditures in 2009 as compared to 2008 is primarily due to the significant activity decline during 2009. Capital expenditures are expected to approach $4.0 billion for the full year 2011.
 
  •  During 2010, 2009 and 2008 Schlumberger made contributions of $868 million, $1.1 billion and $290 million, respectively, to its postretirement benefit plans. The US pension plans were 95% funded at December 31, 2010 based on the projected benefit obligation. This compares to 92% funded at December 31, 2009.
 
Schlumberger’s international defined benefit pension plans are a combined 92% funded at December 31, 2010 based on the projected benefit obligation. This compares to 85% funded at December 31, 2009.
 
Schlumberger currently anticipates contributing approximately $600 million to $650 million to its postretirement benefit plans in 2011, subject to market and business conditions.
 
  •  During 2010 and 2008, certain holders of Schlumberger Limited 1.5% Series A Convertible Debentures due June 1, 2023 and 2.125% Series B Convertible Debentures due June 1, 2023 converted their debentures into Schlumberger common stock. The following table summarizes these conversions:

    $ 321       8.00     $ 448       12.12  
                                 
 
At December 31, 2008, there were no outstanding Series A debentures. There were $321 million outstanding Series B debentures at December 31, 2009. During 2010, $320 million of the 2.125% Series B Convertible Debentures due June 1, 2023 were converted by holders into 8.0 million shares of Schlumberger common stock and the remaining $1 million of outstanding Series B debentures were redeemed for cash.
As of December 31, 2010, Schlumberger had approximately $5.0 billion of cash and short-term investments on hand. Schlumberger had separate committed debt facility agreements aggregating $6.0 billion with commercial banks, of which $3.7 billion was available and unused as of December 31, 2010. This included $4.9 billion of committed facilities which support commercial paper borrowings in the United States and Europe. Schlumberger believes that these amounts are sufficient to meet future business requirements for at least the next twelve months.
Schlumberger’s total outstanding debt at December 31, 2010 was $8.1 billion and included approximately $1.9 billion of commercial paper borrowings. The total outstanding debt increased approximately $2.6 billion compared to December 31, 2009.
On January 10, 2011, Schlumberger issued $1.1 billion of 4.200% Senior Notes due 2021 and $500 million of 2.650% Senior Notes due 2016.

(2) 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 of the Consolidated Financial Statements for details regarding Schlumberger’s pension and other postretirement benefit obligations.
As discussed in Note 14 of the Consolidated Financial Statements, included in the Schlumberger Consolidated Balance Sheet at December 31, 2010 is approximately $1.17 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 which relate to business performance bonds, custom/excise tax commitments, facility lease/rental obligations, etc. These were entered into in the ordinary course of business and are customary practices in the various countries where Schlumberger operates.
 
Critical Accounting Policies and Estimates
 
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires Schlumberger to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenue and expenses. The following accounting policies involve “critical accounting estimates” because they are particularly dependent on estimates and assumptions made by Schlumberger about matters that are inherently uncertain. A summary of all of Schlumberger’s significant accounting policies is included in Note 2 to the Consolidated Financial Statements.
Schlumberger bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
 
Multiclient Seismic Data
 
The WesternGeco segment capitalizes the costs associated with obtaining multiclient seismic data. The carrying value of the multiclient seismic data library at December 31, 2010 and 2009 was $394 million and $288 million, respectively. Such costs are charged to Cost of revenue based on the percentage of the total costs to the estimated total revenue that Schlumberger expects to receive from the sales of such data. However, under no circumstances will an individual survey carry a net book value greater than a 4-year straight-line amortized value.
The carrying value of surveys is reviewed for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Adjustments to the carrying value are recorded when it is determined that estimated future revenues, which involve significant judgment on the part of Schlumberger, would not be sufficient to recover the carrying value of the surveys. Significant adverse changes in Schlumberger’s estimated future cash flows could result in impairment charges in a future period. For purposes of performing the annual impairment test of the multiclient library, future cash flows are analyzed primarily based on two pools of surveys: United States and non-United States. The United States and non-United States pools were determined to be the most appropriate level at which to perform the impairment review based upon a number of factors including (i) various macroeconomic factors that


30


Table of Contents

Part II, Item 7
 
influence the ability to successfully market surveys and (ii) the focus of the sales force and related costs. Certain larger surveys, which are typically prefunded by customers, are analyzed for impairment on a survey by survey basis.
 
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. Depending on how such potential issues are resolved, or if the financial condition of Schlumberger customers were to deteriorate resulting in an impairment of their ability to make payments, adjustments to the allowance may be required.
 
Inventory Reserves
 
Inventory is recorded at the lower of cost or net realizable value. Schlumberger maintains a reserve for excess and obsolete inventory. This requires management to make assumptions about future demand and market conditions. If actual future demand or market conditions are less favorable than those projected by management, additional provisions for excess or obsolete inventory may be required.
 
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 as goodwill. Goodwill is tested for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Goodwill is tested for impairment by comparing the fair value of Schlumberger’s individual reporting units to their carrying amount to determine if there is a potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value.
For purposes of performing the impairment test for goodwill, Schlumberger’s reporting units are primarily the geographic areas comprising the Oilfield Services segment in addition to the WesternGeco, M-I SWACO, Smith Oilfield and Distribution segments. Schlumberger estimates the fair value of these reporting units using a discounted cash flow analysis and/or applying various market multiples. Determining the fair value of a reporting unit is a matter of judgment and often involves the use of significant estimates and assumptions. Schlumberger’s estimate of the fair value of each of its reporting units comprising Oilfield Services as well as its WesternGeco reporting unit were substantially in excess of their respective carrying values at the time of their annual goodwill impairment tests for 2010. Due to the fact that the M-I SWACO, Smith Oilfield and Distribution reporting units were acquired on August 27, 2010, just prior to their annual goodwill impairment tests, the fair value of these reporting units approximated their carrying value.
Long-lived assets, including fixed assets and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involves significant estimates on the part of management. If there is a 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. Schlumberger evaluates the remaining useful life of its intangible assets on a periodic basis to determine whether events and circumstances warrant a revision to the remaining estimated amortization period.
 
Income Taxes
 
Schlumberger’s tax filings are subject to regular audit by the tax authorities in most of the over 100 jurisdictions in which it conducts business. These audits may result in assessments for additional taxes which are resolved with the authorities or, potentially, through the courts. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience


31


Table of Contents

Part II, Item 7
 
and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which 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.
 
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 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 Schlumberger uses reflects the prevailing market rate of a portfolio of high-quality debt instruments with maturities matching the expected timing of the payment of the benefit obligations. The following summarizes the discount rates utilized by Schlumberger for its various pension and postretirement benefit plans:
 
  •  The discount rate utilized to determine the liability for Schlumberger’s United States pension plans and postretirement medical plans was 5.50% at December 31, 2010 and 6.00% at December 31, 2009.
 
  •  The weighted-average discount rate utilized to determine the liability for Schlumberger’s international pension plans was 5.47% at December 31, 2010 and 5.89% at December 31, 2009.
 
  •  The weighted-average discount rate utilized to determine expense for Schlumberger’s United States pension plans and postretirement medical plans decreased from 6.94% in 2009 to 6.00% in 2010.
 
  •  The weighted-average discount rate utilized to determine expense for Schlumberger’s international pension plans was decreased from 6.81% in 2009 to 5.89% in 2010.
 
A higher discount rate decreases the present value of benefit obligations and decreases expense.
The expected rate of return for our 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 expectations regarding future 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 expected rate of return on plan assets for the United States pension plans was 8.50% in both 2010 and 2009. The weighted average expected rate of return on plan assets for the international plans was 8.00% in 2010 and 8.35% in 2009. 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 both the 2010 postretirement medical expense as well as the postretirement medical liability as of December 31, 2010 was 8% graded to 5% over the next six 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, commodity prices and interest rates.
As a multinational company, Schlumberger conducts business in approximately 80 countries. Schlumberger’s functional currency is primarily the US dollar, which is consistent with the oil and gas industry. Approximately 80% of Schlumberger’s revenue in 2010 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.
A 5% increase or decrease in the average exchange rates of all the foreign currencies in 2010 would have changed revenue by approximately 1%. If the 2010 average exchange rates of the US dollar against all foreign currencies had strengthened by 5%, Schlumberger’s income from continuing operations would have increased by approximately 2%. Conversely, a 5% weakening of the US dollar average exchange rates would have decreased income from continuing operations by approximately 3%.
Although the functional currency of Schlumberger’s operations in Venezuela is the US dollar, a portion of the transactions are denominated in local currency. For financial reporting purposes, such transactions are remeasured into US dollars at the official exchange rate, which until January 2010 was fixed at 2.15 Venezuela bolivares fuertes per US dollar, despite significant inflation in recent periods. In January 2010, Venezuela’s currency was devalued and a new exchange rate system was announced. During the first quarter of 2010, Schlumberger began to apply an exchange rate of 4.3 Venezuelan bolivares fuertes per US dollar to its local currency denominated transactions in Venezuela. The devaluation did not have an immediate significant impact to Schlumberger. Further, although this devaluation does result in a reduction in the US dollar reported amount of local currency denominated revenues and expenses, the impact is not material to Schlumberger’s consolidated financial statements.
Schlumberger maintains a foreign-currency risk management strategy that uses derivative instruments to protect its interests from unanticipated fluctuations in earnings and cash flows caused by volatility in currency exchange rates. Foreign currency forward contracts and foreign currency options provide a hedge against currency fluctuations either on monetary assets/liabilities denominated in other than a functional currency or on expenses.
At December 31, 2010, contracts were outstanding for the US dollar equivalent of $7.3 billion in various foreign currencies.
Schlumberger is subject to the risk of market price fluctuations of certain commodities, such as metals and fuel. Schlumberger utilizes forward contracts to manage a small percentage of the price risk associated with forecasted metal purchases. As of December 31, 2010, $12 million of commodity forward contracts were outstanding.
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 interest rate swaps to mitigate the exposure to changes in interest rates. At December 31, 2010, Schlumberger had fixed rate debt aggregating approximately $5.4 billion and variable rate debt aggregating approximately $2.8 billion. Schlumberger has entered into interest rate swaps relating to $0.5 billion of its fixed rate debt as of December 31, 2010 whereby Schlumberger will receive interest at a fixed rate and pay interest at a variable rate.
Schlumberger’s exposure to interest rate risk associated with its debt is also partially mitigated by its investment portfolio. Both Short-term investments and Fixed income investments, held to maturity, which totaled approximately $3.7 billion at December 31, 2010, are comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds and are substantially all denominated in US dollars. The average return on investment was 1.1% in 2010.

Forward-looking Statements
 
This Form 10-K and other statements we make contain “forward-looking statements” within the meaning of the federal securities laws, which include any statements that are not historical facts, such as our forecasts or expectations regarding business outlook; growth for Schlumberger as a whole and for each of Oilfield Services and WesternGeco (and for specified products or geographic areas within each segment); the integration of both Smith and Geoservices into our business; the anticipated benefits of those transactions; oil and natural gas demand and production growth; oil and natural gas prices; improvements in operating procedures and technology; capital expenditures by Schlumberger and the oil and gas industry; the business strategies of Schlumberger’s customers; future global economic conditions; and future results of operations. These statements are subject to risks and uncertainties, including, but not limited to, the current global economic downturn; changes in exploration and production spending by Schlumberger’s customers and changes in the level of oil and natural gas exploration and development; general economic and business conditions in key regions of the world; pricing erosion; seasonal factors; changes in government regulations and regulatory requirements, including those related to offshore oil and gas exploration, radioactive sources, explosives, chemicals, hydraulic fracturing services and climate-related initiatives; continuing operational delays or program reductions as of result of the lifted drilling moratorium in the Gulf of Mexico; the inability to successfully integrate the merged Smith and Geoservices businesses and to realize expected synergies, the inability to retain key employees; and other risks and uncertainties detailed in the Risk Factors section of this Form 10-K and other filings that we make with the Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of such a development changes), or should our underlying assumptions prove incorrect, actual outcomes may vary materially from those reflected in our forward-looking statements. Schlumberger disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

Part II, Item 8
 
 
1.   Business Description
 
Schlumberger Limited (Schlumberger N.V., incorporated in Curaçao) and its consolidated subsidiaries (collectively, “Schlumberger”) form the world’s leading supplier of technology, integrated project management, and information solutions to customers in the oil and gas industry worldwide, providing the industry’s widest range of oilfield services from exploration to production.
 
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.
 
Principles of Consolidation
 
The accompanying Consolidated Financial Statements include the accounts of Schlumberger, its wholly-owned subsidiaries, and subsidiaries over which it exercises a controlling financial interest. All significant intercompany transactions and balances have been eliminated. Investments in entities 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, net. Investments in which Schlumberger does not have the ability to exercise significant influence are accounted for using the cost method. Both equity and cost method investments are classified in Investments in Affiliated Companies.
 
Reclassifications
 
Certain prior year items have been reclassified to conform to the current year presentation.
 
Use of Estimates
 
The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, Schlumberger evaluates its estimates, including those related to collectibility of accounts receivable; valuation of inventories and investments; recoverability of goodwill, intangible assets 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 on various 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
 
Schlumberger recognizes revenue based upon purchase orders, contracts or other persuasive evidence of an arrangement with the customer that include fixed or determinable prices provided that collectibility is reasonably assured. Revenue is recognized for services when they are rendered. Revenue is recognized for products upon delivery, when the customer assumes the risks and rewards of ownership. Certain products may be provided on a consigned basis in which case revenue is recognized when the products are consumed provided that all other revenue recognition criteria have been met.
Revenue from seismic contract services performed on a dayrate basis is recognized as the service is performed. Revenue from other contract services, including pre-funded multiclient surveys, is recognized as the seismic data is acquired and/or processed on a proportionate basis as work is performed. This method requires revenue to be recognized based upon quantifiable measures of progress, such as square kilometers acquired. Multiclient data surveys are licensed or sold to customers on a non-transferable basis. Revenue on completed multiclient data surveys is recognized upon obtaining a signed licensing agreement and providing customers with access to such data.

Part II, Item 8
 
 
Revenue is occasionally generated from contractual arrangements that include multiple deliverables. Revenue from these arrangements is recognized as each item is delivered based on their relative fair value and when the delivered items have stand-alone value to the customer.
Revenue derived from the sale of licenses of Schlumberger software may include installation, maintenance, consulting and training services. If services are not essential to the functionality of the software, the revenue for each element of the contract is recognized separately based on its respective vendor specific objective evidence of fair value when all of the following conditions are met: a signed contract is obtained, delivery has occurred, the fee is fixed or determinable and collectibility is probable.
 
Translation of Non-United States Currencies
 
The functional currency of Schlumberger is primarily the US dollar. Assets and liabilities recorded in functional currencies other than US dollars are translated at period end exchange rates. The resulting adjustments are charged or credited directly to the Equity section of the Consolidated Balance Sheet. Revenue and expenses are translated at the weighted-average exchange rates for the period. Realized and unrealized transaction gains and losses are included in income in the period in which they occur. Transaction losses of $27 million net of hedging activities, were recognized in 2010. In 2009 and 2008, transaction gains net of hedging activities of $73 million and $8 million, respectively, were recognized.
 
Investments
 
The Consolidated Balance Sheet reflects the Schlumberger investment portfolio separated between current and long term, based on maturity. Both Short-term investments and Fixed Income Investments, held to maturity are comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds, and are substantially denominated in US dollars. Under normal circumstances it is the intent of Schlumberger to hold the investments until maturity, with the exception of investments that are considered trading (December 31, 2010 – $189 million; December 31, 2009 – $184 million). Short-term investments that are designated as trading are stated at fair value, which is estimated using quoted market prices for those or similar investments. All other investments are stated at cost plus accrued interest, which approximates market. The unrealized gains/losses on investments designated as trading were not significant at both December 31, 2010 and 2009.
For purposes of the Consolidated Statement of Cash Flows, Schlumberger does not consider short-term investments to be cash equivalents as a significant portion have original maturities in excess of three months.
Fixed Income Investments, held to maturity at December 31, 2010 of $484 million mature as follows: $289 million in 2012, $80 million in 2013 and $115 million in 2014.
 
Inventories
 
Inventories are stated at average cost or at market, whichever is lower. Costs included in Inventories consist of materials, direct labor and manufacturing overhead.
 
Fixed Assets and Depreciation
 
Fixed assets are stated at cost less accumulated depreciation, which is provided for by charges to income over the estimated useful lives of the assets using the straight-line method. Fixed assets include the manufacturing cost of oilfield technical equipment manufactured or assembled by subsidiaries of Schlumberger. Expenditures for replacements and improvements are capitalized. Maintenance and repairs are charged to operating expenses as incurred. Upon sale or other disposition, the applicable amounts of asset cost and accumulated depreciation are removed from the balance sheet and the net amount, less proceeds from disposal, is charged or credited to income.
 
Multiclient Seismic Data
 
The multiclient library consists of completed and in-process seismic surveys that are licensed on a nonexclusive basis. Multiclient surveys are primarily generated utilizing Schlumberger resources. Schlumberger capitalizes costs directly


42

Part II, Item 8
 
 
incurred in acquiring and processing the multiclient seismic data. Such costs are charged to Cost of revenue 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 involves 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.
 
Goodwill, Other Intangibles and Long-lived Assets
 
Schlumberger records the excess of purchase price over the fair value of the tangible and identifiable intangible assets acquired as goodwill. Goodwill is tested for impairment annually as well as when an event or change in circumstance indicates an impairment may have occurred. Goodwill is tested for impairment by comparing the fair value of Schlumberger’s individual reporting units to their carrying amount to determine if there is a potential goodwill impairment. If the fair value of the reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the implied fair value of the goodwill of the reporting unit is less than its carrying value.
Long-lived assets, including fixed assets and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing for impairment, the carrying value of such assets is compared to the estimated undiscounted future cash flows expected from the use of the assets and their eventual disposition. If such cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying value of the long-lived asset to its estimated fair value. The determination of future cash flows as well as the estimated fair value of long-lived assets involve 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.
Intangible assets consist primarily of customer relationships, technology/technical know-how and tradenames acquired in business combinations. Customer relationships are generally amortized over periods ranging from 7 to 28 years, acquired technology/technical know-how are generally amortized over periods ranging from 5 to 18 years and tradenames are generally amortized over periods ranging from 5 years to 30 years.
 
Taxes on Income
 
Schlumberger computes taxes on income in accordance with the tax rules and regulations of the many taxing authorities where the income is earned. The income tax rates imposed by these taxing authorities vary substantially. Taxable income may differ from pretax income for financial accounting purposes. To the extent that differences are due to revenue or expense items reported in one period for tax purposes and in another period for financial accounting purposes, an appropriate provision for deferred income taxes is made. Any effect of changes in income tax rates or tax laws are included in the provision for income taxes in the period of enactment. When it is more likely than not that a portion or all of the deferred tax asset will not be realized in the future, Schlumberger provides a corresponding valuation allowance against deferred tax assets.
Schlumberger’s tax filings are subject to regular audit by the tax authorities in most of the jurisdictions in which it conducts business. These audits may result in assessments for additional taxes which are resolved with the authorities or, potentially, through the courts. Schlumberger recognizes the impact of a tax position in its financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Tax liabilities are recorded based on estimates of additional taxes which will be due upon the conclusion of these audits. Estimates of these tax liabilities are made based upon prior experience and are updated in light of changes in facts and circumstances. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of audits may result in liabilities which could be materially different from these estimates. In such an event, Schlumberger will record additional tax expense or tax benefit in the year in which such resolution occurs.


43

Part II, Item 8
 
 
Schlumberger generally does not provide income taxes relating to undistributed earnings, as the earnings either would not be taxable when remitted or are considered to be indefinitely reinvested.
 
Concentration of Credit Risk
 
Schlumberger’s assets that are exposed to concentrations of credit risk consist primarily of cash, short-term investments, fixed income investments held to maturity, receivables from clients and derivative financial instruments. Schlumberger places its cash, short-term investments and fixed income investments held to maturity with financial institutions and corporations, and limits the amount of credit exposure with any one of them. Schlumberger regularly evaluates the creditworthiness of the issuers in which it invests. The receivables from clients are spread over many countries and customers. Schlumberger maintains an allowance for uncollectible accounts receivable based on expected collectibility and performs ongoing credit evaluations of its customers’ financial condition. By using derivative financial instruments to hedge exposure to changes in exchange rates and commodity prices, 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.
 
Research & Engineering
 
All research and engineering expenditures are expensed as incurred.
 
Earnings per Share
 
Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the year. Diluted earnings per share is calculated by first adding back to net income the interest expense on any outstanding convertible debentures and then dividing this adjusted net income attributable to Schlumberger by the sum of (i) unvested restricted stock units; and (ii) the weighted average number of common shares outstanding assuming dilution. The weighted average number of common shares outstanding assuming dilution assumes (a) that all stock options which are in the money are exercised at the beginning of the period and that the proceeds are used by Schlumberger to purchase shares at the average market price for the period, and (b) the conversion of any outstanding convertible debentures.

  •  A pretax and after-tax charge of $63 million primarily relating to the early termination of a vessel lease associated with WesternGeco’s electromagnetic service offering as well as related assets, including a $30 million impairment related to an equity-method investment.
 
  •  In connection with the Schlumberger’s merger with Smith (see Note 4 – Acquisitions), Schlumberger recorded the following pretax charges: $56 million ($55 million after-tax) of merger-related transaction costs including advisory and legal fees, $41 million ($35 million after-tax) relating to employee benefits for change in control payments and retention bonuses and $38 million ($24 million after-tax) relating to the amortization of purchase accounting adjustments associated with the write-up of acquired inventory to its estimated fair value.
 
  •  $40 million pretax charge ($36 million after-tax) for the early termination of rig contracts and workforce reductions in Mexico due to the slowdown of project activity.
 
  •  Schlumberger repurchased $352 million of its 6.50% Notes due 2012 and, as a result, incurred a pretax charge of $28 million ($18 million after-tax).
 
  •  Schlumberger recorded a pretax gain of $1.27 billion ($1.24 billion after-tax) as a result of remeasuring its previously held 40% equity interest in the M-I SWACO joint venture. Refer to Note 4 – Acquisitions for further details.
 
First quarter of 2010:
 
  •  Schlumberger incurred $35 million of pretax and after-tax merger-related costs in connection with the Smith and Geoservices transactions (see Note 4 – Acquisitions). These costs primarily consisted of advisory and legal fees.
 
  •  During March 2010, the Patient Protection and Affordable Care Act (PPACA) was signed into law in the United States. Among other things, the PPACA eliminates the tax deductibility of retiree prescription drug benefits to the extent of the Medicare Part D subsidy that companies, such as Schlumberger, receive. As a result of this change in law, Schlumberger recorded a $40 million charge to adjust its deferred tax assets to reflect the loss of this future tax deduction.

4.   Acquisitions
 
Merger with Smith International, Inc.
 
On August 27, 2010, Schlumberger acquired all of the outstanding shares of Smith, a leading supplier of premium products and services to the oil and gas exploration and production industry. The merger brings together the complementary drilling and measurements technologies and expertise of Schlumberger and Smith in order to facilitate the engineering of complete drilling systems which optimize all of the components of the drill string. Such systems will enable Schlumberger’s customers to achieve improved drilling efficiency, better well placement and increased wellbore assurance as they face increasingly more challenging environments. In addition, Schlumberger’s geographic footprint will facilitate the extension of joint offerings on a worldwide basis.
Under the terms of the merger agreement, Smith became a wholly-owned subsidiary of Schlumberger. Each share of Smith common stock issued and outstanding immediately prior to the effective time of the merger was converted into the right to receive 0.6966 shares of Schlumberger common stock, with cash paid in lieu of fractional shares.
At the effective time of the merger, each outstanding option to purchase Smith common stock was converted pursuant to the merger agreement into a stock option to acquire shares of Schlumberger common stock on the same terms and conditions as were in effect immediately prior to the completion of the merger. The number of shares of Schlumberger common stock underlying each converted Smith stock option was determined by multiplying the number of Smith stock options by the 0.6966 exchange ratio, and rounding down to the nearest whole share. The exercise price per share of each converted Smith stock option was determined by dividing the per share exercise price of such stock option by the 0.6966 exchange ratio, and rounded up to the nearest whole cent. Smith stock options, whether or not then vested and exercisable, became fully vested and exercisable and assumed by Schlumberger at the effective date of the merger in accordance with preexisting change-in-control provisions. Smith stock options were converted into 0.6 million of Schlumberger stock options.
At the effective time of the merger, Smith restricted stock units, whether or not then vested, became fully vested (except for grants between the date of the merger agreement and closing, which were not significant and did not automatically vest) and were converted into shares of Schlumberger common stock in connection with the merger, determined by multiplying the number of shares of Smith common stock subject to each award by the 0.6966 exchange ratio, rounded to the nearest whole share (assuming, in the case of performance-based Smith restricted stock unit awards, the deemed attainment of the performance goals under the award at the target level).

(1) Schlumberger recorded an adjustment of approximately $155 million to write-up the acquired inventory to its estimated fair value. Schlumberger’s cost of revenue reflected this increased valuation as this inventory was sold. Accordingly, Schlumberger’s margins were temporarily reduced in the initial periods subsequent to the merger.
(2) In connection with the merger, Schlumberger assumed all of the debt obligations of Smith including its long-term fixed rate notes consisting of the following: $220 million 6.75% Senior Notes due 2011, $300 million 8.625% Senior Notes due 2014, $275 million 6.00% Senior Notes due 2016 and $700 million 9.75% Senior Notes due 2019. Schlumberger recorded a $417 million adjustment to increase the carrying amount of these notes to their estimated fair value. This adjustment will be amortized as a reduction of interest expense over the remaining term of the respective obligations.
(3) 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. Included in the provisions for deferred taxes are amounts relating to the outside basis difference associated with shares in certain Smith non-US subsidiaries for which no taxes have previously been provided. Schlumberger expects to reverse the outside basis difference primarily through the reorganization of those subsidiaries as well as through repatriating earnings in lieu of permanently reinvesting them. In this regard, Schlumberger is in the process of assessing certain factors that impact the ultimate amount of deferred taxes to be recorded. The amount of deferred taxes recorded will likely be revised after this assessment is completed. Any revision to the amount of deferred taxes recorded will impact the amount of goodwill recorded.

(4) Prior to the completion of the merger, Smith and Schlumberger operated M-I SWACO, a drilling fluids joint venture that was 40% owned by Schlumberger and 60% owned by Smith. Effective at the closing of the merger, M-I SWACO is now owned 100% by Schlumberger. As a result of obtaining control of this joint venture, Schlumberger was required under generally accepted accounting principles to remeasure its previously held equity interest in the joint venture at its merger-date fair value and recognize the resulting pretax gain of $1.3 billion ($1.2 billion after-tax) in earnings. This gain is classified as Gain on Investment in M-I SWACO in the Consolidated Statement of Income.
Prior to acquiring Smith, Schlumberger recorded income relating to this venture using the equity method of accounting. The carrying value of Schlumberger’s investment in the joint venture on December 31, 2009 was $1.4 billion, and was included within Investments in Affiliated Companies on the Consolidated Balance Sheet. Schlumberger’s equity income from this joint venture was $78 million in 2010 (representing the period from January 1, 2010 to August 27, 2010), $131 million in 2009 and $210 million in 2008. Schlumberger received cash distributions from the joint venture of $50 million in 2010, $106 million in 2009 and $57 million in 2008.
(5) The goodwill recognized is primarily attributable to expected synergies that will result from combining the operations of Schlumberger and Smith as well as intangible assets that do not qualify for separate recognition. Approximately $0.2 billion of the goodwill is deductible for income tax purposes.
 
Acquisition of Geoservices
 
On April 23, 2010, Schlumberger completed the acquisition of Geoservices, a privately owned oilfield services company specializing in mud logging, slickline and production surveillance operations, for $915 million in cash.
The purchase price has been allocated to the net assets acquired upon their estimated fair values as follows:
 
           
(Stated in millions)        
Cash
    $ 26  
Other assets
      184  
Fixed assets

      (145 )
Deferred tax liabilities
      (64 )
Other liabilities
      (152 )
 
 
      $ 915  
           
 
The long-term debt was repaid at the time of closing.
Intangible assets recorded in connection with this transaction, which primarily relate to customer relationships, will be amortized over a weighted average period of approximately 17 years. The amount allocated to goodwill represents the excess of the purchase price over the fair value of the net assets acquired and is not tax deductible for income tax purposes.
 
Other Acquisitions
 
Schlumberger has made other acquisitions and minority investments, none of which were significant on an individual basis, for cash payments, net of cash acquired, of $212 million during 2010, $514 million during 2009, and $345 million during 2008.
 
Supplemental Pro Forma Data
 
Smith’s results of operations have been included in Schlumberger’s financial statements for periods subsequent to the effective date of the merger. Smith contributed revenues of $3.3 billion and net income of $160 million (including the recurring effects of purchase accounting) to Schlumberger for the period from the closing of the merger through December 31, 2010. The following unaudited supplemental pro forma data (“pro forma data”) presents consolidated information as if the merger with Smith and the acquisition of Geoservices had been completed on January 1, 2009:

The pro forma data was prepared based on the historical financial information of Schlumberger, Smith and Geoservices and has been adjusted to give effect to pro forma adjustments that are (i) directly attributable to the transactions, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The pro forma data is not necessarily indicative of what Schlumberger’s results of operations actually would have been had the transactions been completed on January 1, 2009. Additionally, the pro forma data does not purport to project the future results of operations of the combined company nor do they reflect the expected realization of synergies associated with the transactions. The pro forma data reflects the application of the following adjustments:
 
  •  Elimination of the gain resulting from Schlumberger’s remeasurement of its previously held 40% equity interest in M-I SWACO, which is considered non-recurring.
 
  •  Additional depreciation and amortization expense associated with fair value adjustments to acquired identifiable intangible assets and property, plant and equipment.
 
  •  Elimination of charges incurred in 2010 related to the fair value adjustments to Smith’s inventory that has been sold as they will not have a long-term continuing impact.
 
  •  Reductions in interest expense as a result of increasing the carrying value of acquired debt obligations to its estimated fair value.
 
  •  Elimination of transaction costs incurred in 2010 that are directly related to the transactions, and do not have a continuing impact on the combined company’s operating results.
 
  •  The issuance of 176 million of shares of Schlumberger common stock.
 
Included in the 2010 and 2009 pro forma net income attributable to Schlumberger and diluted earnings per share presented above are the following significant charges and credits:

The fair value adjustment presented above represents changes in the fair value of the portion of Schlumberger’s fixed rate debt that is hedged through the use of interest rate swaps.
During the third and fourth quarters of 2010, Schlumberger repurchased all of its $650 million 6.50% Notes due 2012.
During the first quarter of 2009, Schlumberger entered into a €3.0 billion Euro Medium Term Note program. This program provides for the issuance of various types of debt instruments such as fixed or floating rate notes in euro, US dollar or other currencies.
Schlumberger issued €1.0 billion 2.75% Guaranteed Notes due 2015 in the fourth quarter of 2010 under this program. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 2.56%. Schlumberger also issued €1.0 billion 4.50% Guaranteed Notes due 2014 in the first quarter of 2009 under this program. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 4.95%.
During the third quarter of 2009, Schlumberger issued $450 million of 3.00% Guaranteed Notes due 2013.

In September 2008, Schlumberger issued €500 million 5.25% Guaranteed Notes due 2013. Schlumberger entered into agreements to swap these euro notes for US dollars on the date of issue until maturity, effectively making this a US dollar denominated debt on which Schlumberger will pay interest in US dollars at a rate of 4.74%.
Commercial paper borrowings outstanding at December 31, 2010 and 2009 include certain notes issued in currencies other than the US dollar which were swapped for US dollars and pounds sterling on the date of issue until maturity. Commercial paper borrowings are classified as long-term debt to the extent of their backup 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.
At December 31, 2010, Schlumberger had separate committed debt facility agreements aggregating $6.0 billion with commercial banks, of which $3.7 billion was available and unused. This included $4.9 billion of committed facilities which support commercial paper programs in the United States and Europe, of which $2.5 billion mature in December 2011 and $2.4 billion mature in April 2012. Interest rates and other terms of borrowing under these lines of credit vary from country to country. Borrowings under the commercial paper programs at December 31, 2010 were $1.9 billion ($0.4 billion at December 31, 2009). At December 31, 2010, $1.5 billion of the commercial paper borrowings were classified within Long-term debt – current portion in the Consolidated Balance Sheet.
On January 10, 2011, Schlumberger issued $1.1 billion of 4.200% Senior Notes due 2021 and $500 million of 2.650% Senior Notes due 2016.
A summary of Long-term Debt by currency, analyzed by Bonds and Notes, Commercial Paper (CP) and Other, at December 31 follows. As described in further detail above, the currencies are presented after taking into account currency swaps entered into on the date of issuance until maturity.
