None.
Item 9A. 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 effec-
tiveness of the design and operation of Schlumberger’s disclosure controls and procedures. Based upon Schlumberger’s
evaluation, the CEO and the CFO have concluded that, as of December 31, 2010, the disclosure controls and procedures
were effective to provide reasonable assurance that information required to be disclosed in the reports Schlumberger
files and submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the
time periods specified in SEC rules and forms.
There has been no change in Schlumberger’s internal control over financial reporting that occurred during the
quarter ended December 31, 2010 that has materially affected, or is reasonably likely to materially affect, Schlum-
berger’s internal control over financial reporting.
See Management’s Report on Internal Control Over Financial Reporting.
