The cost of such awards should be measured at fair value at the date of grant. SFAS 123R provides public companies with a choice of transition methods to implement the standard. Schlumberger will apply the modified prospective method whereby compensation cost will be recognized for the unamortized portion of vested awards outstanding at January 1, 2006, the effective date of SFAS 123R, and granted after January 1, 1995. Such cost will be recognized in Schlumberger’s financial statements over the remaining vesting ~~period.~~periods. As described above, in 2003 Schlumberger adopted the fair value recognition provisions of SFAS Nos. 123 and 148 on a prospective basis for grants after January 1, 2003. Therefore, effective January 1, 2006, Schlumberger will have to apply the provisions of SFAS 123R to the unvested portion of awards granted during the period of January 1, 1995 to December 31, ~~2002. The~~2002; the adoption of this standard ~~is expected~~ to ~~reduce~~result in an additional charge to Schlumberger’s earnings byof approximately $20 million in 2006 and $5 million in 2007.

15.Contingencies

TheConsolidated Balance Sheet includes accruals for the estimated future costs associated with certain environmental remediation activities related to the past use or disposal of hazardous materials where it is probable that Schlumberger has incurred a liability and such amount can be reasonably estimated.

~~-14-~~

Substantially all such costs relate to divested operations and to facilities or locations that are no longer in operation. Due to a number of uncertainties, including uncertainty of timing, the scope of remediation, future technology, regulatory changes, the risk of personal injury, natural resource or property damage claims and other factors, it is possible that the ultimate remediation costs may exceed the amounts estimated. However, in the opinion of management, such additional costs are not expected to be material relative to consolidated liquidity, financial position or future results of operations.

TheConsolidated Balance Sheet includes accruals for estimated future expenditures associated with business divestitures which have been completed. It is possible that the ultimate expenditures may exceed the amounts recorded. In the opinion of management, such additional expenditures are not expected to be material relative to consolidated liquidity, financial position or future results of operations.

In December 2004, WesternGeco and Schlumberger received grand jury subpoenas from the US Attorney’s office in the Southern District of Texas seeking documents relating to possible fraud in obtaining visas for non-US citizens working as crewmembers on vessels operating in the Gulf of Mexico. We are in the process of responding to the investigation, including providing information sought by the subpoenas. Schlumberger is unable to determine the outcome of this matter and the related impact it might have on Schlumberger’s financial condition and results of operations.

In addition, Schlumberger and its subsidiaries are party to various other legal proceedings. A liability is accrued when a loss is both probable and can be reasonably estimable. At this time the ultimate disposition of these proceedings is not presently determinable and therefore, it is not possible to estimate the amount of loss or range of possible losses that might result from an adverse judgment on settlement in these matters. However, in the opinion of Schlumberger, any liability that might ensue would not be material in relation to the consolidated liquidity, financial position or future results of operations.

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. 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.

Pretax operating income represents the segments’ income before taxes and minority interest. Pretax operating income excludes corporate expenses (including $6 million relating to assets lost and damaged during the third quarter 2005 hurricanes in the Gulf of Mexico), interest income, interest expense and amortization of certain intangibles, stock-based compensation costs and the~~Credits~~Charges and ~~Charges~~Creditsdescribed in detail on pages 6, 7 and 78 as these items are not allocated to the segments.

~~Second~~Third Quarter 2005 Compared to ~~Second~~Third Quarter 2004

Operating revenue for the ~~second~~third quarter of 2005 was ~~$3.43~~$3.70 billion versus ~~$2.83~~$2.91 billion for the same period last year. Income from continuing operations before taxes and minority interest was $740 million in 2005 compared to $381 million in 2004. The 2005 results include a pretax credit of $18 million, and 2004 include pretax charges of $14 million. These charges and credits are described in detail on pages 6, 7 and 8.

Net income for the third quarter of 2005 was $541 million compared to $318 million for the same period last year. Net income includes a gain from discontinued operations of $20 million in 2004.

Oilfield Services revenue of $3.26 billion increased 7% sequentially and 25% compared to the same quarter of last year. Pretax business segment operating income of $722 million increased 7% sequentially and 64% year-on-year.

WesternGeco revenue of $436 million increased 14% sequentially and 45% year-on-year. Pretax business segment operating income of $85 million increased 48% sequentially and 158% year-on-year.

OILFIELD SERVICES

Third-quarter revenue of $3.26 billion was 7% higher sequentially and increased 25% year-on-year. Pretax operating income of $722 million increased 7% sequentially and 64% year-on-year.

Sequential revenue increases were recorded across all geographic areas, with Europe/CIS/West Africa and Middle East & Asia displaying the strongest growth rates. By technology, Drilling & Measurements, Well Completions & Productivity, and Well Services led sequential growth.

Year-on-year, all four geographic areas posted growth of at least 20%. All technologies recorded significant increases driven by robust new technology introduction, coupled with increased activity and favorable pricing.

Pretax operating income recorded strong sequential growth with the exception of North America, which was affected by the hurricane season in the Gulf of Mexico. Strengthening exploration and production activity worldwide led to improved pricing across all geographic areas.

-18-

North America

Revenue of $946 million increased 4% sequentially and 20% year-on-year. Pretax operating income of $219 million declined 6% sequentially but increased 84% year-on-year.

Canada recorded strong sequential growth with the rapid recovery in rig count following spring break-up, combined with sustained improved pricing. The growth in US Land revenue resulted from the combination of positive trends in activity and favorable pricing. Gulf Coast activity declined substantially during the quarter with the suspension of operations due to the severe hurricane season.

The sequential decline in operating income was the result of the severity of the hurricane season, and includes the combined effects of reduced resource utilization and business disruption costs. The total estimated financial impact of hurricanes during the third quarter for the Gulf Coast and US Land GeoMarkets was $60 million in lost revenue and $44 million in lost operating income.

The steep year-on-year operating income growth was primarily due to double-digit price increases, particularly for Well Services, Wireline, and Drilling & Measurements technologies, together with continuing activity growth.

Latin America

Revenue of $569 million was 3% higher sequentially and 31% higher year-on-year. Pretax operating income of $92 million increased 9% sequentially and 104% year-on-year.

Sequential revenue improvement was due to an expanding customer base and an Integrated Project Management (IPM) project that included a performance-related incentive payment in the Peru/Colombia/Ecuador GeoMarket. In Brazil, increasing activity was experienced with strong deployment of Drilling & Measurements and Wireline technology services. Revenue improvement was partially offset by Mexico, which declined during the quarter, primarily due to a drop in IPM third-party managed services revenue.

Revenue in Venezuela improved as a result of rising PDVSA drilling activity, partially offset by a slowdown in international operator activity offshore Venezuela. During the quarter, PRISA barge utilization activity in Western Venezuela exceeded an average of 90%. Discussions regarding the settlement of certain outstanding receivables for the PRISA contract were progressing at quarter-end.

The year-on-year revenue growth was experienced across all four GeoMarkets. The most significant contributions came from Venezuela with the resumption of the activity for PDVSA in the Lake Maracaibo, and from the Peru/Colombia/Ecuador GeoMarket due to an expanding IPM portfolio.

Increasing operating efficiency in the Latin America South and Peru/Colombia/Ecuador GeoMarkets led partly to the sequential operating income improvement. The marked year-on-year operating income improvement was due to strengthening profitability in integrated projects coupled with strong Drilling & Measurements technology results throughout Latin America.

Europe/CIS/West Africa

Revenue of $944 million increased 14% sequentially and 28% year-on-year. Pretax operating income of $201 million increased 31% sequentially and 71% year-on-year.

Sequential revenue growth was partially due to continued strong activity in Russia, particularly for Drilling & Measurements and Well Completions & Productivity technologies, combined with the first full quarter of financial consolidation of PetroAlliance operations.

West Africa experienced strong activity improvement with continued deepwater activity growth benefiting mainly Wireline and Drilling & Measurements technologies. The North Sea GeoMarket also contributed to the revenue growth, with increased drilling activity and strong demand for production technologies from Well Services and Wireline.

The year-on-year revenue growth was principally due to Russia with the consolidation of PetroAlliance operations, coupled with higher activity in the North Sea and West Africa.

Sequentially, Drilling & Measurements, Well Services, and Well Completions & Productivity technologies showed the strongest rise in operating income from increased pricing and activity, particularly in the North Sea, West Africa, and Russia GeoMarkets. All seven Europe/CIS/West Africa GeoMarkets delivered operating margin improvements resulting in a sequential increase of 270 basis points due to price increases in a tight supply environment. The year-on-year operating income increase was led by Drilling & Measurements technology driven by improved activity levels and stronger pricing mainly in the North Sea, West Africa and Russia GeoMarkets.

Middle East & Asia

Revenue of $774 million was 6% higher sequentially and 25% higher year-on-year. Pretax operating income of $226 million increased 9% sequentially and 36% year-on-year.

The sequential revenue growth was mainly due to the increase in rig count in the Saudi Arabia/Bahrain/Kuwait GeoMarket, as Saudi Aramco continues to increase activity in line with their announced spending plans.

In the Brunei/Malaysia/Philippines GeoMarket, sequential revenue grew sharply due to higher customer expenditures, improving pricing, and a move by operators into increased deepwater exploration. This resulted in high levels of activity in testing operations, as well as demand for Drilling & Measurements technology services. The Gulf GeoMarket also contributed to the sequential revenue growth through firm pricing.

The year-on-year revenue growth was mainly due to a sharp activity increase in the Saudi Arabia/Bahrain/Kuwait and Gulf GeoMarkets, coupled with strong deepwater exploration activity in the Brunei/Malaysia/Philippines GeoMarket.

Sustained activity, rising pricing, and improved market share gain resulted in operating margins approaching 30% in the quarter. The strong sequential operating income growth was driven by Drilling & Measurements and Wireline technology services that benefited from an increasing rig count and a strengthening pricing environment. The year-on-year operating income growth was mainly driven by a combination of higher activity and more favorable pricing in Saudi together with sharp activity increases in the Brunei/Malaysia/Philippines GeoMarket.

WESTERNGECO

Third-quarter revenue of $436 million increased 14% sequentially and 45% compared to the same period last year. Pretax operating income of $85 million improved 48% sequentially and $52 million year-on-year.

Sequentially, Marine revenue increased sharply as overall vessel utilization improved to 92% and Q-vessel utilization reached 100% in the quarter. In Europe, three Q* vessels and the Q-Seabed* crew were active throughout the quarter. In addition, one new project began in Sakhalin and higher activity was experienced in West Africa. These results were partly mitigated by lower revenue in South America, Mexico, and the Middle East following the transfer of vessels to other regions. The sharp revenue growth also reflected much improved contractual terms and conditions, including mobilization, demobilization, and weather downtime provisions.

However, Land, Data Processing, and Multiclient revenues experienced seasonal declines during the quarter. In Land, the start of a new project in Algeria was insufficient to overcome the results of the standby of two crews in Africa due to the rainy season. In Data Processing, higher revenues in South America and Russia were unable to compensate for lower activity in Mexico. Multiclient sales were $95 million, which declined due to office closures in New Orleans and Houston as a result of hurricane activity.

The year-on-year revenue increase was led by Marine due to better vessel utilization combined with a 74% year-on-year price improvement and favorable terms and conditions on most contracts.

Sequential improvement in operating income was mainly due to Marine, driven by higher vessel utilization and strong pricing.

The overall impact of Hurricanes Katrina and Rita led to estimated lost operating revenue of $13 million and lost operating income of $9 million for the quarter.

Backlog reached $656 million versus $595 million at the end of the second quarter.

OTHER

Interest and other income for the third quarter of 2005 was $80 million versus $37 million for the same period last year. The third quarter of 2005 included an $18 million gain relating to the resolution of a contingency associated with the March 2005 sale of a facility in Montrouge, France and a $6 million gain relating to sales of certain assets. Interest income of $27 million increased $12 million compared to the same quarter last year. The average return on investment increased from 2.2% to 3.4% while the average investment balance of $3.1 billion increased by $560 million compared to last year.

Gross margin increased from 20.8% in 2004 to 25.4% in 2005, primarily due to a combination of record activity levels in Oilfield Services with operations at capacity in a number of regions, and continued pricing improvements in both Oilfield Services and WesternGeco. Research and engineering expense, as a percentage of revenue decreased from 4.1% to 3.5%. In absolute dollars, both marketing expense and general and administrative expenses were essentially flat, but decreased as a percentage of revenue.

Interest expense of $51 million increased $7 million compared to the same quarter last year. Average borrowing rates of 4.5% increased from 3.6% last year. The average debt balance of $4.5 billion increased by $69 million compared to the same quarter last year.

The effective tax rate for the third quarter of 2005 was 23.6% compared to 19.5% in the prior year. This increase is primarily attributable to the country mix of results in Oilfield Services, with a higher proportion of pretax profitability in higher tax jurisdictions. Additionally, the prior year rate was positively impacted to a relatively larger degree by the resolution of non-US tax audits.

Nine Months 2005 Compared to Nine Months 2004

The sequential decline in pretax operating income was mainly due to lower Multiclient sales. This seasonal deterioration was partially offset by significant improvements in Marine as a result of increased vessel utilization, better pricing, and the conversion of a conventional vessel to Q-Technology* commanding higher prices. The increase in the year-on-year pretax income was led by Multiclient (up $25 million) due mainly to increased sales. Data Processing increased $6 million due to the combined impact of higher revenue, and lower lease and compensation costs in the United Kingdom. Land improved by $6 million mainly in the Middle East due to higher revenue.

All technologies recorded strong growth year-on-year with the exception of Integrated Project Management.

~~WESTERNGECO~~

Six months revenue for WesternGeco of $761 million was 26% higher compared to the same period last year. The year-on-year increase in Marine revenue was attributable to better vessel utilization and pricing improvements. Marine activity increased mainly in South America, Asia, Europe, West Africa and Middle East, partially offset by lower activity in Mexico and in North America. Land activity increased mainly in the Middle East with several additional crews active in the current year, higher activity in Algeria and in Argentina, partially offset by Mexico and Malaysia. Multiclient sales increased mainly in North America, augmented by higher sales in Europe and in Asia. Data Processing increased from higher levels of third party processing.

Pretax income of $121 million improved by $73 million year-on-year. Marine, Land Multiclient and Data processing all experienced increases in pretax income primarily due to increased revenue, better pricing and utilization, partly offset by higher operating costs. In addition, approximately 67% of Multiclient sales in the current period, which increased 15% year-on-year to $250 million, had no net book value due to the prior amortization of capitalized costs as compared to 54% in the prior year period.

~~INCOME STATEMENT~~

Interest and other income was $235 million versus $51 million for the same period last year. The 2005 period includes a gain of $146 million on the sale of a facility in Montrouge, France while the 2004 period included a $21 million loss on the sale of shares of Atos Origin SA. Both of these items are described in further detail in the following pages. Interest income of $43 million increased $18 million compared to the same period last year. The average return on investment increased from 1.7% to 3.1% while the average investment balance of $2.8 billion decreased $132 million compared to last year.

Gross margin increased from 21.0% in 2004 to 24.8% in 2005, primarily due to a combination of record activity levels in Oilfield Services, with operations at capacity in a number of regions, and continued pricing improvements in both Oilfield Services and WesternGeco. As a percentage of revenue, marketing expense was flat compared to last year. In absolute dollars, research and engineering expense increased slightly, but as a percentage of revenue decreased from 4.2% to 3.7%. General and administrative expense as a percentage of revenue decreased from 2.9% to 2.7%2.6%.

Excluding the impact of the net $64 million charge in 2004 related to the US interest rate swaps described on page 7, interest expense decreased ~~$23~~$16 million, and average borrowing rates increased from ~~3.9%~~3.5% in 2004 to ~~4.3%~~4.4% in 2005.

CASH FLOW

During the first ~~six~~nine months of 2005, cash provided by operations was ~~$1.08~~$1.9 billion as income from continuing operations plus depreciation/amortization and credits/charges were partially offset by increases in customer receivables and inventories. Cash used by investing activities was ~~$596 million,~~$1.2 billion, with investments in fixed assets ($~~699 million)~~1.1 billion) and ~~the acquisition of PetroAlliance~~acquisitions ($3293 million) offset in part by proceeds from the sale of the Montrouge facility ($230 million). Cash used by financing activities was ~~$543~~$770 million as the payment of dividends to shareholders ($~~234~~358 million), stock repurchase plan ($~~262~~408 million) and a net reduction in debt of ~~$165~~$197 million were only partially offset by the proceeds from employee stock plans ($~~119~~207 million).

Net Debt is gross debt less cash, short-term investments and fixed income investments held to maturity. Management believes that “net debt” provides useful information regarding the level of Schlumberger’s indebtedness by reflecting cash and investments that could be used to repay debt, and that the level of net debt provides useful information as to the results of Schlumberger’s deleveraging efforts. Details of the change in Net Debt follows:

FORWARD-LOOKING STATEMENTS

This report and other statements we make contain forward looking statements, which include any statements that are not historical facts, such as our expectations regarding business outlook; growth for Schlumberger as a whole and for each of Oilfield Services and WesternGeco; oil and natural gas demand and production growth; operating and capital expenditures by Schlumberger and the oil and gas industry; the business strategies of ~~Schlumberger’s~~Schlumberger and its customers; ~~future~~ effective tax rates; and future results of operations. These statements involve risks and uncertainties, including, but not limited to, the global economy; 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; political and economic uncertainty and socio-political unrest; and other factors detailed in our most recent Form 10-K, this Form 10-Q and other filings with the Securities and Exchange Commission. If one or more of these risks or uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those forecasted or expected. Schlumberger disclaims any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

Non-US Operations

Schlumberger derives a significant portion of its revenues from non-US operations, which subject Schlumberger to risks which may affect such operations. Schlumberger’s non-US operations accounted for approximately 77% and 74% of our consolidated revenues for the ~~second~~third quarter of 2005 and 2004, respectively; and 75% and 74% for the first ~~six~~nine months of ~~both~~ 2005 and ~~2004.~~2004, respectively. The proportion of revenues generated from non-US operations has increased from 2004 to 2005 due to the significant impact of the third quarter 2005 hurricanes in the US. Risks which may adversely affect our operations in such countries include unsettled political and economic conditions in certain areas, exposure to possible expropriation or other governmental actions, social unrest, acts of terrorism, outbreak of war or other armed conflict, deprivation of contract rights, exchange control and currency fluctuation. In addition, we are subject to risks

-27-

associated with our operations in countries, including Iran, Syria, Sudan, Libya and Cuba, which are subject to trade, economic sanctions or other restrictions imposed by the US government. Although it is impossible to predict such occurrences or their effects on Schlumberger, management believes these risks are acceptable. Management also believes that the geographical diversification of our activities reduces the risk that loss of operations in any one country would be material to all the operations taken as a whole.

Item 3: Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting Schlumberger, see Item 7A, “Quantitative Disclosures About Market Risk,” of our Annual Report on Form 10-K for the year ended December 31, 2004. Schlumberger’s exposure to market risk has not changed materially since December 31, 2004.

Item 4: Controls and Procedures

As of the end of the period covered by this report, an evaluation was carried out under the supervision and with the participation of Schlumberger’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of Schlumberger’s disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934 (the “Exchange Act”). Based on that evaluation, the CEO and CFO have concluded that Schlumberger’s disclosure controls and procedures were effective as of ~~June~~September 30, 2005 to ensure that information required to be disclosed by Schlumberger in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. There has been no change in our internal controls over financial reporting that occurred during the quarter ended ~~June~~September 30, 2005 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
