Item 7.01 Regulation FD Disclosure.

Schlumberger Limited (“Schlumberger or the “Company”) currently reports its results on the basis of two business segments, Oilfield Services and WesternGeco, and by geographical areas within Oilfield Services. As a result of the recent acquisitions of Smith International, Inc. (“Smith”) and Geoservices, Schlumberger previously announced that Schlumberger will change its primary reporting to product group segments (the “Groups”), effective with the first quarter of 2011. The Company will also continue to report its results on a geographical basis.

The Groups are as follows:

	•		*Reservoir Characterization Group*: This group will consist of the principal Technologies involved in the finding and defining of hydrocarbon deposits. These include WesternGeco, Wireline, Well Testing, Schlumberger Information Services, and Data & Consulting Services.

	•		*Drilling Group*: This group will be comprised of Bits & Advanced Technologies, M-I SWACO, Geoservices, Drilling & Measurements, PathFinder, Drilling Tools & Remedial Services, Dynamic Pressure Management and IPM well construction projects.

	•		*Reservoir Production Group*: Includes Well Services, Completions and Artificial Lift Technologies together with Subsea and Water and Carbon Services activities, and the production activities of IPM.

The Groups will collectively be referred to as “Oilfield Services.” Additionally, Schlumberger will also report the distribution business acquired in the Smith transaction as a separate segment.

The above changes will be reflected in the consolidated financial statements and segment reporting beginning in fiscal year 2011, starting with the Form 10-Q for the three months ended March 31, 2011. To provide an additional perspective on these changes, Schlumberger has prepared and furnishes as Exhibit 99.1 to this Form 8-K unaudited pro forma historical consolidated financial information (“Pro Forma Information”) on the basis of the new reporting structure, giving effect to the acquisitions of Smith and Geoservices as if they had occurred on January 1, 2008.

The Pro Forma Information is based on the historical consolidated statements of income of Schlumberger, Smith and Geoservices. The Pro Forma Information has been adjusted to reflect pro forma events that are directly attributable to the transactions and factually supportable. As such, the Pro Forma Information does not reflect any cost savings, operating synergies or revenue enhancements that the combined companies may achieve as a result of the transactions, the costs to integrate the operations of Schlumberger, Smith and Geoservices, or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

The Pro Forma Information has been presented for informational purposes only and is not necessarily indicative of what the combined companies’ results of operations would have been had the transactions actually been completed as of January 1, 2008. In addition, the Pro Forma Information does not purport to project the future operating results of the combined companies.

Exhibit 99.1

Schlumberger Limited

Unaudited Pro Forma Historical

Consolidated Financial Information

Unaudited Pro Forma Historical Consolidated Financial Information

Schlumberger Limited (“Schlumberger” or the “Company”) currently reports its results on the basis of two business segments, Oilfield Services and WesternGeco, and by geographical areas within Oilfield Services. As a result of the recent acquisitions of Smith International, Inc. (“Smith”) and Geoservices, Schlumberger has reached a point where its coverage of the various activities comprising exploration and production services is so broad that the Company will be changing the primary way in which it allocates resources and assesses performance. Consequently, as previously announced and effective with the first quarter of 2011, Schlumberger will change its primary reporting to product group segments (the “Groups”). Schlumberger believes that this change will give investors a better perspective on the different parts of its business. The Company will also continue to report its results on a geographical basis.

The Groups are as follows:

	•		*Reservoir Characterization Group:* This group will consist of the principal Technologies involved in the finding and defining of hydrocarbon deposits. These include WesternGeco, Wireline, Well Testing, Schlumberger Information Services, and Data & Consulting Services.

	•		*Drilling Group:* This group will be comprised of Bits & Advanced Technologies, M-I SWACO, Geoservices, Drilling & Measurements, PathFinder, Drilling Tools & Remedial Services, Dynamic Pressure Management and IPM well construction projects.

	•		*Reservoir Production Group*: Includes Well Services, Completions and Artificial Lift Technologies together with Subsea and Water and Carbon Services activities, and the production activities of IPM.

The Groups will collectively be referred to as “Oilfield Services.” Additionally, Schlumberger will also report the distribution business acquired in the Smith transaction, as a separate segment.

The above changes will be reflected in the consolidated financial statements and segment reporting beginning in fiscal year 2011, starting with the Form 10-Q for the three months ended March 31, 2011. To provide additional perspective on these changes, Schlumberger has prepared the accompanying unaudited pro forma historical consolidated financial information (“Pro Forma Information”) on the basis of the new reporting structure, giving effect to the acquisitions of Smith and Geoservices as if they had occurred on January 1, 2008.

The Pro Forma Information has been presented for informational purposes only and is not necessarily indicative of what the combined company’s results of operations would have been had the transactions actually been completed as of January 1, 2008. In addition, the Pro Forma Information does not purport to project the future operating results of the combined companies.

Notes to the Schlumberger Limited Unaudited Pro Forma Historical
Consolidated Financial Information

(1)		Includes depreciation and amortization expense associated with fair value adjustments to Smith’s acquired assets of approximately $50 million per quarter.

(2)		Reflects a reduction in interest expense of approximately $15 million per quarter as a result of fair value adjustments recorded in purchase accounting relating to Smith’s long-term fixed rate debt.

(3)		Diluted shares outstanding was calculated by taking the Schlumberger historical diluted shares outstanding and adding the approximately 176 million shares of Schlumberger common stock issued in connection with the Smith transaction.

(4)		The calculation of diluted earnings per share reflects the adding back of interest expense associated with Schlumberger’s outstanding convertible debentures to net income, as appropriate, for each period presented.

Diluted earnings per share excluding Charges & Credits and effective tax rate excluding Charges & Credits are non-GAAP financial measures. Schlumberger management believes that the exclusion of Charges & Credits from the foregoing financial measures enables it to evaluate more effectively, Schlumberger’s operations period over period and to identify operating trends that could otherwise be masked by the excluded items. The foregoing non-GAAP financial measures should be considered in addition to, not as a substitute for, or superior to other measures of financial performance prepared in accordance with GAAP.
