Ladies and Gentlemen:

Pursuant to Rule 461 of the rules and regulations promulgated under the Securities Act of 1933, as amended, Schlumberger Limited (Schlumberger N.V.) (the “Company”) hereby requests that the Securities and Exchange Commission (the “Commission”) accelerate the effectiveness of its Registration Statement on Form S-4 (File No. 333-166326), as amended by Pre-Effective Amendment No. 1 filed with the Commission on June 17, 2010 and Pre-Effective Amendment No. 2 filed with the Commission on July 16, 2010, so that such registration statement will become effective on Tuesday, July 20, 2010, at 10 a.m., New York time, or as soon thereafter as is practicable.

• the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and

• the Company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

Very truly yours,
