NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

The accompanying unaudited consolidated financial statements of Schlumberger Limited and its subsidiaries (“Schlumberger”) have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of Schlumberger management, all adjustments considered necessary for a fair statement have been included in the accompanying unaudited financial statements. All intercompany transactions and balances have been eliminated in consolidation. Operating results for the three-month period ended March 31, 2012 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2012. The December 31, 2011 balance sheet information has been derived from the Schlumberger 2011 financial statements. For further information, refer to the Consolidated Financial Statements and notes thereto, included in the Schlumberger Annual Report on Form 10-K for the year ended December 31, 2011, filed with the Securities and Exchange Commission on February 1, 2012.

2. Charges and Credits

⁽¹⁾  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 first quarter of 2011, Schlumberger issued $1.1 billion of 4.200% Senior Notes due 2021.

During the first quarter of 2011, Schlumberger issued $500 million of 2.650% Senior Notes due 2016. Schlumberger entered into agreements to swap these dollar notes for euros on the date of issue until maturity, effectively making this a euro denominated debt on which Schlumberger will pay interest in euros at a rate of 2.39%.

During the first quarter of 2011, Schlumberger repurchased all of the outstanding 9.75% Senior Notes due 2019, the 8.625% Senior Notes due 2014 and the 6.00% Senior Notes due 2016 for approximately $1.26 billion. These transactions did not result in any significant gains or losses.

-10-

The estimated fair value of Schlumberger’s Long-term Debt at March 31, 2012 and December 31, 2011, based on quoted market prices, was $8.8 billion and $8.9 billion, respectively.

10. Derivative Instruments and Hedging Activities

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

Foreign Currency Exchange Rate Risk

As a multinational company, Schlumberger conducts business in approximately 85 countries. Schlumberger’s functional currency is primarily the US dollar, which is consistent with the oil and gas industry. However, outside the United States, a significant portion of Schlumberger’s expenses is incurred in foreign currencies. Therefore, when the US dollar weakens (strengthens) in relation to the foreign currencies of the countries in which Schlumberger conducts business, the US dollar–reported expenses will increase (decrease).

Schlumberger is exposed to risks on future cash flows to the extent that local currency expenses exceed revenues denominated in local currency that are other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to provide a hedge against a portion of these cash flow risks. These contracts are accounted for as cash flow hedges, with the effective portion of changes in the fair value of the hedge recorded on the Consolidated Balance Sheet and in Accumulated Other Comprehensive Loss. Amounts recorded in Accumulated Other Comprehensive Loss are reclassified into earnings in the same period or periods that the hedged item is recognized in earnings. The ineffective portion of changes in the fair value of hedging instruments, if any, is recorded directly to earnings.

At March 31, 2012, Schlumberger recognized a cumulative net $19 million gain in Equity relating to revaluation of foreign currency forward contracts and foreign currency options designated as cash flow hedges, the majority of which is expected to be reclassified into earnings within the next twelve months.

Schlumberger is also exposed to changes in the fair value of assets and liabilities, including certain of its long-term debt, which are denominated in currencies other than the functional currency. Schlumberger uses foreign currency forward contracts and foreign currency options to hedge this exposure as it relates to certain currencies. These contracts are accounted for as fair value hedges with the fair value of the contracts recorded on the Consolidated Balance Sheet and changes in the fair value recognized in the Consolidated Statement of Income along with the change in fair value of the hedged item.

At March 31, 2012, contracts were outstanding for the US dollar equivalent of $5.2 billion in various foreign currencies, of which $3.9 billion relate to hedges of debt denominated in currencies other than the functional currency.

Commodity Price Risk

Schlumberger is exposed to the impact of market fluctuations in the price 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. The objective of these contracts is to reduce the variability of cash flows associated with the forecasted purchase of those commodities. These contracts do not qualify for hedge accounting treatment and therefore, changes in the fair value of the forward contracts are recorded directly to earnings.

At March 31, 2012, $23 million of commodity forward contracts were outstanding.

Interest Rate Risk

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

During the third quarter of 2009, Schlumberger entered into an interest rate swap relating to a certain debt instrument. The swap was for a notional amount of $450 million in order to hedge changes in the fair value of Schlumberger’s $450 million 3.00% Notes due 2013. Under the terms of this swap, Schlumberger receives interest at a fixed rate of 3.0% annually and will pay interest quarterly at a floating rate of three-month LIBOR plus a spread of 0.765%. This interest rate swap is designated as a fair value hedge of the underlying debt. This derivative instrument is marked to market with gains and losses recognized currently in income to offset the respective losses and gains recognized on changes in the fair value of the hedged debt. This results in no net gain or loss being recognized in the Consolidated Statement of Income.

-11-

At March 31, 2012, Schlumberger had fixed rate debt aggregating $7.7 billion and variable rate debt aggregating $2.5 billion, after taking into account the effects of the interest rate swaps.

Short-term investments and Fixed income investments, held to maturity, totaled $3.0 billion at March 31, 2012, and were comprised primarily of money market funds, eurodollar time deposits, certificates of deposit, commercial paper, euro notes and Eurobonds, and were substantially all denominated in US dollars. The carrying value of these investments approximated fair value, which was estimated using quoted market prices for those or similar investments.

The fair values of outstanding derivative instruments are summarized as follows:

12. Contingencies

In 2007, Schlumberger received an inquiry from the United States Department of Justice (“DOJ”) related to the DOJ’s investigation of whether certain freight forwarding and customs clearance services of Panalpina, Inc., and other companies provided to oil and oilfield service companies, including Schlumberger, violated the Foreign Corrupt Practices Act. Schlumberger is cooperating with the governmental authorities.

In 2009, Schlumberger learned that United States officials began a grand jury investigation and an associated regulatory inquiry, both related to certain Schlumberger operations in specified countries that are subject to United States trade and economic sanctions. Also in 2009, prior to being acquired by 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. Schlumberger is cooperating with the governmental authorities.

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. Pursuant to a contract between M-I SWACO and BP, M-I SWACO provided certain services under the direction of BP. A number of legal actions, certain of which name an M-I SWACO entity as a defendant, have been filed in connection with the Deepwater Horizon incident, and additional legal actions may be filed in the future. Based on information currently known, the amount of any potential loss attributable to M-I SWACO with respect to potential liabilities related to the incident would not be material to Schlumberger’s consolidated financial statements.

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

OILFIELD SERVICES

First-quarter revenue of $9.92 billion decreased 4% sequentially. The strong year-end product, software and multiclient sales experienced in the fourth quarter of 2011 accounted for approximately two-thirds of the sequential decrease in revenue in the first quarter of 2012.

Reservoir Characterization Group revenue decreased primarily on lower WesternGeco multiclient and Schlumberger Information Solutions (SIS) software sales following the fourth quarter of 2011 seasonal highs, but these effects were partially offset by higher WesternGeco marine acquisition activity. Drilling Group revenue was flat as higher M-I SWACO sales in North America land, increasing deepwater activity in the US Gulf of Mexico, and robust international activity across the Group were offset by lower Integrated Project Management (IPM) operations in the Mexico and Iraq GeoMarkets. Production Group revenue decreased sequentially on lower Well Services pricing and fleet utilization in North America land, the effect of strong year-end Artificial Lift and Completions Systems equipment sales experienced in the fourth quarter of 2011, and lower Framo and Schlumberger Production Management activities.

On a geographical basis, North America Area revenue decreased due to lower WesternGeco multiclient sales following the strong fourth-quarter 2011 results. Revenue was otherwise flat sequentially as the decline in US land was partially offset by the stronger winter exploration activity in Western Canada and Alaska, although the effect in Canada was muted by the very early spring break-up. Area revenue also benefited from increased drilling and deepwater exploration activity in the US Gulf of Mexico. In the Latin America Area, revenue declined in the Mexico & Central America GeoMarket from lower IPM project activities; in the Peru, Colombia & Ecuador GeoMarket from the effect of the strong product sales seen in the fourth quarter of 2011; and in the Brazil GeoMarket from reduced WesternGeco multiclient sales. These declines, however, were partially offset by higher WesternGeco marine activity in the Venezuela, Trinidad & Tobago GeoMarket and higher shale-related activity that benefited Well Services, Wireline and M-I SWACO in the Argentina, Bolivia and Chile GeoMarket. In the Europe/CIS/Africa Area, revenue decreased following the seasonally strong product and software sales of the fourth quarter of 2011, and sluggish winter activity in Russia and the North Sea GeoMarket. These factors more than offset Area revenue growth attributable to strong exploration activities in the Southern and Eastern Africa GeoMarket; a continued resumption of activities in the Libya GeoMarket; and robust M-I SWACO sales in the Nigeria and Gulf of Guinea Africa GeoMarket. In the Middle East & Asia Area, revenue decreased from the effect of seasonally strong product and software sales in the fourth quarter of 2011. Reduced IPM project activity in Iraq and the shutdown of operations in Syria and South Sudan also contributed to this decline although the effect was largely mitigated by increased activity in the East Asia GeoMarket following the monsoon-related slowdowns of the fourth quarter of 2011.

First-quarter pretax operating income of $1.94 billion decreased 10% sequentially. Pretax operating margin decreased 147 basis points (bps) sequentially to 19.6% primarily due to the reduced software and product sales as well as to the lower WesternGeco multiclient sales. North America pretax operating margin decreased 409 bps sequentially to 22.8% from lower WesternGeco multiclient sales and reduced Well Services asset utilization and pricing. International pretax operating margin was flat at 19.1%, with the increase in high-margin exploration and deepwater activities helping sustain robust international margins despite the significant impact of the fourth-quarter 2011 product, software and multiclient sales and the seasonal drop in activity in Russia and the North Sea during the first quarter of 2012.

Reservoir Characterization Group

First-quarter revenue of $2.59 billion was 7% lower sequentially. Pretax operating income of $672 million was 14% lower compared to prior quarter.

Sequentially, revenue decreased primarily on lower WesternGeco multiclient and SIS software sales following their fourth-quarter 2011 seasonal highs, but these effects were partially offset by increased WesternGeco marine acquisition on higher vessel utilization. Wireline revenue was flat as strong activity in the North America and Latin America Areas was offset by slowdowns in the Europe/CIS/Africa and Middle East & Asia Areas due to weather and seasonality. Excluding seasonality, the Group grew on stronger deepwater and exploration activity in Sub-Sahara Africa, Latin America and the US Gulf of Mexico.

Pretax operating margin decreased 189 bps sequentially to 26% primarily due to the seasonally lower WesternGeco multiclient and SIS software sales but this effect was partially mitigated by higher WesternGeco vessel utilization on lower marine transits. Excluding seasonality, margins improved through deepwater and exploration activities and better WesternGeco vessel utilization.

-18-

Drilling Group

First-quarter revenue of $3.78 billion was flat sequentially. Pretax operating income of $657 million was 1% higher than the fourth quarter.

Sequentially, revenue was flat as higher M-I SWACO sales in North America land, increasing deepwater activity in the US Gulf of Mexico, and robust international activity across the Group were offset by lower IPM activity in the Mexico & Central America and Iraq GeoMarkets. Drilling & Measurements revenue slipped marginally due to winter weather in Russia, although this was partially offset by higher activities in the Latin America and Middle East and Asia Areas. Bits and Advanced Technologies revenue decreased slightly due to the effect of the seasonal product sales experienced in the fourth quarter of 2011.

Sequentially, pretax operating margin increased 28 bps to 17.4% due to stronger M-I SWACO pricing in North America land, the Group’s increasing high-margin deepwater activity in North America, and an increased international footprint for former Smith Technologies.

Production Group

First-quarter revenue of $3.54 billion decreased 4% sequentially. Pretax operating income of $621 million was 20% lower sequentially.

Sequentially, revenue decreased on lower Well Services pricing and fleet utilization in North America land, the effect of the exceptional Artificial Lift and Completions Systems equipment sales seen in the fourth quarter of 2011, and lower Framo and Schlumberger Production Management activities. The transition of Well Services activities from gas-rich to liquids-rich basins in North America also impacted results as the reduced fleet utilization and new industry pressure-pumping capacity led to competitive pricing declines.

First-quarter pretax operating margin decreased 338 bps to 17.6% reflecting pricing erosion for Well Services technologies through increased competitive forces from the introduction of new industry pressure-pumping capacity into liquids plays following the industry migration from gas-rich basins. Operating margin was also affected by reduced asset fleet utilization and cost inflation for certain materials. The seasonally lower Artificial Lift and Completions Systems equipment sales also contributed to the margin decline.

⁽²⁾  Excludes interest included in the Product Group and Geographical Area results.

OILFIELD SERVICES

First-quarter 2012 revenue of $9.92 billion was 22% higher than the same period last year largely due to the significantly improved activity of Well Services technologies in North America and an increase in M-I SWACO, Wireline and Drilling & Measurements exploration activities.

-20-

First-quarter 2012 pretax operating margin increased 167 bps to 19.6% as a result of higher-margin exploration activities that benefited Wireline and Drilling & Measurements, improved multiclient sales and marine utilization at WesternGeco, partially offset by a decline in margins for Well Services technologies, primarily in North America, as a result of pricing pressure and cost inflation. The first-quarter 2011 margins were adversely impacted by the geopolitical events in North Africa and the Middle East, as well as severe weather in the US and Australia.

Reservoir Characterization Group

First-quarter 2012 revenue of $2.59 billion was 18% higher than the same period last year led by Wireline improvements across all Areas, driven by improved offshore revenues in the US Gulf of Mexico combined with strong performances in the Brazil, Saudi Arabia, Bahrain and Nigeria & Gulf of Guinea Africa GeoMarkets. Testing Services and SIS also increased, mainly in the Latin America and Europe/CIS/Africa Areas, while WesternGeco was up on the improvements in marine activity coupled with stronger multiclient sales.

Year-on-year, pretax operating margin increased 502 basis points to 26.0% largely due to the higher-margin exploration activities that benefited Wireline and the improvements at WesternGeco. The first-quarter 2011 margins were adversely impacted by the geopolitical events in North Africa and the Middle East as well as severe weather in Australia.

Drilling Group

First-quarter 2012 revenue of $3.78 billion was 22% higher than the previous year primarily due to significantly improved activity of M-I SWACO in North America and Europe/CIS/Africa Areas, coupled with stronger demand for Drilling & Measurements services across most Areas, most notably in North America as a result of the resumption of activity in the US Gulf of Mexico. Drilling Tools & Remedial and Pathfinder technologies also increased, mainly driven by growth in North America.

Year-on-year, pretax operating margin increased 244 basis points to 17.4% as a result of the sharp increase in M-I SWACO activity and strong contribution from Drilling & Measurements particularly with the resumption of high-margin deepwater activity in the US Gulf of Mexico, as well as the strong performances of Drilling Tools & Remedial and Pathfinder technologies.

Production Group

First-quarter 2012 revenue of $3.54 billion increased 26% year-on-year, with notable growth in North America, due to a combination of capacity additions and improvements in asset utilization of Well Services Technologies. Well Services also posted significant growth internationally. Well Intervention Services, Completion Systems and Artificial Lift technologies also contributed to the Group’s growth.

Year-on-year, pretax operating margin decreased 134 basis points to 17.6% primarily due to Well Services in North America, reflecting pricing pressure and cost inflation.

Research & engineering		2.6	%		2.9	%
General & administrative		0.9	%		1.1	%

Interest expense for the first quarter of 2012 was $80 million as compared to $73 million for the same period in 2011. This increase was primarily attributable to the long-term debt that Schlumberger issued during 2011.

The effective tax rate for the first quarter of 2012 was 23.9% compared to 23.8% for the same period in 2011.

CHARGES AND CREDITS

Schlumberger recorded the following charges and credits during the first quarters of 2012 and 2011.

2012:

In the first quarter of 2012, Schlumberger recorded $15 million of pretax merger and integration-related charges ($13 million after-tax) in connection with the acquisition of Smith. This amount is classified in Merger & integration in the Consolidated Statement of Income.

2011:

In the first quarter of 2011, Schlumberger recorded $34 million pretax merger and integration related charges ($28 million after-tax) in connection with the acquisition of Smith and Geoservices. This amount is classified in Merger & integration in the Consolidated Statement of Income.

Key liquidity events during the first three months of 2012 and 2011 included:

• 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 $6.5 billion had been repurchased as of March 31, 2012. On July 21, 2011, the Schlumberger Board of Directors approved an extension of this repurchase program to December 31, 2013.

The following table summarizes the activity, during the three months ended March 31, under the April 17, 2008 share repurchase program:

	(Stated in millions except per share amounts)
	Total cost of shares purchased		Total number of shares purchased		Average price paid per share
First quarter 2012	$	324		4.4	$	74.01
First quarter 2011	$	844		9.7	$	87.18

• Cash flow provided by operations was $0.7 billion in the first quarter of 2012 compared to $0.8 billion in the first quarter of 2011 with the increase in earnings before depreciation and amortization expense offset in part by an increase in working capital requirements.

• Capital expenditures were $1.0 billion in the first quarter of 2012 compared to $0.8 billion during the first quarter of 2011. Capital expenditures for the full year of 2012 are expected to approach $4.5 billion as compared to $4.0 billion in 2011.

• During the first quarter of 2011, Schlumberger issued $1.1 billion of 4.20% Senior Notes due 2021 and $500 million of 2.65% Senior Notes due 2016.

• During the first quarter of 2011, Schlumberger repurchased all of its outstanding 9.75% Senior Notes due 2019, 8.625% Senior Notes due 2014 and 6.00% Senior Notes due 2016 for approximately $1.26 billion.

At times, Schlumberger experiences delays in payments from certain of its customers. Schlumberger operates in approximately 85 countries. At March 31, 2012, only five of those countries individually accounted for greater than 5% of Schlumberger’s accounts receivable balance and only one, where cash collections are received on a timely and regular basis, represented greater than 10%. A delay in payment or the nonpayment of amounts that are owed to Schlumberger could have a material adverse effect on Schlumberger’s results of operations and cash flows.

As of March 31, 2012 Schlumberger had $4.1 billion of cash and short-term investments on hand. Schlumberger had separate committed debt facility agreements aggregating $4.1 billion with commercial banks, of which $2.8 billion was available and unused as of March 31, 2012. This included $3.5 billion of committed facilities which support commercial paper programs 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 had $1.0 billion of commercial paper outstanding as of March 31, 2012.

FORWARD-LOOKING STATEMENTS

This Form 10-Q 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 its segments (and for specified products or geographic areas within each segment); oil and natural gas demand and production growth; oil and natural gas prices; Schlumberger’s effective tax rate; 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, current global economic conditions; 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, political and business conditions in key regions of the world; pricing erosion; weather and seasonal factors; the ability to respond to increased activity levels; 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; the inability of technology to meet new challenges in exploration; and other risks and uncertainties detailed in our first-quarter 2012 earnings release, our most recent 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.

Schlumberger’s exposure to market risk has not changed materially since December 31, 2011.

Item 4. Controls and Procedures.

Schlumberger has carried out an evaluation under the supervision and with the participation of Schlumberger’s management, including the Chief Executive Officer (“CEO”) and the Chief Financial Officer (“CFO”), of the effectiveness of Schlumberger’s “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this report, Schlumberger’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports that Schlumberger files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Schlumberger’s disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is accumulated and communicated to its management, including the CEO and the CFO, as appropriate, to allow timely decisions regarding required disclosure. There has been no change in Schlumberger’s internal control over financial reporting that occurred during the quarter to which this report relates that has materially affected, or is reasonably likely to materially affect, Schlumberger’s internal control over financial reporting.

	Total number of shares purchased		Average price paid per share		Total number of shares purchased as part of publicly announced program		Maximum value of shares that may yet be purchased under the program

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