Exhibit A

SCHLUMBERGER LIMITED

WAIVER AND RELEASE

Schlumberger Limited has offered to pay me certain benefits (“Benefits”) pursuant to my Employment Agreement with Schlumberger Limited, effective as of March 1^st, 2013 (the “Agreement”), which are in addition to any remuneration or benefits to which I am already entitled. These Benefits were offered to me in exchange for my agreement, among other things, to waive all of my claims against and release Schlumberger Limited and its predecessors, successors and assigns (collectively referred to as the “Company”), all of the affiliates (including parents and subsidiaries) of the Company (collectively referred to as the “Affiliates”) and the Company’s and Affiliates’ directors and officers, employees and agents, employee benefit plans and the fiduciaries and agents of said plans (collectively, with the Company and Affiliates, referred to as the “Corporate Group”) from any and all claims, demands, actions, liabilities and damages arising out of or relating in any way to my employment with or separation from the Company or the Affiliates; provided, however, that this Waiver and Release shall not apply to any claim or cause of action to enforce or interpret any provision contained in the Agreement. I have read this Waiver and Release and the Agreement (which, together, are referred to herein as the “Agreement Materials”) and the Agreement is incorporated herein by reference. The provision of the Benefits is voluntary on the part of the Company and is not required by any legal obligation other than the Agreement. I choose to accept this offer.

I understand that signing this Waiver and Release is an important legal act. I acknowledge that the Company has advised me in writing to consult an attorney before signing this Waiver and Release. I understand that, in order to be eligible for Benefits, I must sign (and return to Sivakumar Nadarajah, Executive Compensation, Schlumberger Limited, 5599 San Felipe, 17^th Floor, Houston, TX 77056) this Waiver and Release by 5 p.m. on March 22, 2013. I acknowledge that I have been given at least 21 days to consider whether to sign the Agreement and whether to execute this Waiver and Release.

In exchange for the payment to me of Benefits, which are in addition to any remuneration or benefits to which I am already entitled, I, among other things, (1) agree not to sue the Corporate Group in any local, state and/or federal court regarding or relating in any way to my employment with or separation from the Company or the Affiliates, and (2) knowingly and voluntarily waive all claims and release the Corporate Group from any and all claims, demands, actions, liabilities, and damages, whether known or unknown, arising out of or relating in any way to my employment with or separation from the Company or the Affiliates, except to the extent that my rights are vested under the terms of employee benefit plans sponsored by the Company or the Affiliates and except with respect to such rights or claims as may arise after the date this Waiver and Release is executed. This Waiver and Release includes, but is not limited to, claims and causes of action under: Title VII of the Civil Rights Act of 1964, as amended (“Title VII”); the

9

Age Discrimination in Employment Act of 1967, as amended, including the Older Workers Benefit Protection Act of 1990 (“ADEA”); the Civil Rights Act of 1866, as amended; the Civil Rights Act of 1991; the Americans with Disabilities Act of 1990 (“ADA”); the Energy Reorganization Act, as amended, 42 U.S.C. § 5851; the Workers Adjustment and Retraining Notification Act of 1988; the Pregnancy Discrimination Act of 1978; the Employee Retirement Income Security Act of 1974, as amended; the Family and Medical Leave Act of 1993; the Fair Labor Standards Act; the Occupational Safety and Health Act; claims in connection with workers’ compensation or “whistle blower” statutes; and/or contract, tort, defamation, slander, wrongful termination or any other state or federal regulatory, statutory or common law. Further, I expressly represent that no promise or agreement which is not expressed in the Agreement Materials has been made to me in executing this Waiver and Release, and that I am relying on my own judgment in executing this Waiver and Release, and that I am not relying on any statement or representation of the Company, any of the Affiliates or any other member of the Corporate Group or any of their agents. I agree that this Waiver and Release is valid, fair, adequate and reasonable, is with my full knowledge and consent, was not procured through fraud, duress or mistake and has not had the effect of misleading, misinforming or failing to inform me. Notwithstanding the above, nothing in this Agreement is intended to release or affect in any way any board resolution or by-law of the Company or other agreement between me and the Company which may provide for indemnity and/or director and officer insurance coverage relating to any potential claim against me arising out of my role as an officer and employee of the Company.

I acknowledge that payment of Benefits to me by the Company is not an admission by the Company or any other member of the Corporate Group that they engaged in any wrongful or unlawful act or that the Company or any member of the Corporate Group violated any federal or state law or regulation. Except as provided in the Agreement Materials, I acknowledge that neither the Company nor any other member of the Corporate Group has promised me continued employment or represented to me that I will be rehired in the future. I acknowledge that the Company and I contemplate an unequivocal, complete and final dissolution of my employment relationship. I acknowledge that this Waiver and Release does not create any right on my part to be rehired by the Company or the Affiliates and I hereby waive any right to future employment by the Company or any other member of the Corporate Group.

Both the Company and I agree to refrain from any criticisms or disparaging comments about each other or in any way relating to my employment or separation and the Company and I specifically acknowledge that our willingness to enter into this Waiver and Release is in anticipation of our fidelity to this commitment. The above is not intended to restrict me from seeking or engaging in other employment and, in that connection, from making confidential disclosure to potential employers of such facts or opinions as I may elect to convey, nor is it intended to restrict Schlumberger from conducting such confidential internal communications as may be necessary to manage this resignation in a businesslike way.

10

Should any of the provisions set forth in this Waiver and Release be determined to be invalid by a court, agency or other tribunal of competent jurisdiction, it is agreed that such determination shall not affect the enforceability of other provisions of this Waiver and Release. I acknowledge that this Waiver and Release and the other Agreement Materials set forth the entire understanding and agreement between me and the Company or any other member of the Corporate Group concerning the subject matter of this Waiver and Release and supersede any prior or contemporaneous oral and/or written agreements or representations, if any, between me and the Company or any other member of the Corporate Group. I understand that for a period of 7 calendar days following the date that I sign this Waiver and Release, I may revoke my acceptance of the offer, provided that my written statement of revocation is received on or before that seventh day by Sivakumar Nadarajah, Director Executive Compensation of Schlumberger Limited - Houston, in which case the Waiver and Release will not become effective. In the event I revoke my acceptance of this offer, the Company shall have no obligation to provide me Benefits. I understand that failure to revoke my acceptance of the offer within 7 calendar days from the date I sign this Waiver and Release will result in this Waiver and Release being permanent and irrevocable.

I acknowledge that I have read this Waiver and Release, have had an opportunity to ask questions and have it explained to me and that I understand that this Waiver and Release will have the effect of knowingly and voluntarily waiving any action I might pursue, including breach of contract, personal injury, retaliation, discrimination on the basis of race, age, sex, national origin, or disability and any other claims arising prior to the date of this Waiver and Release. By execution of this document, I do not waive or release or otherwise relinquish any legal rights I may have which are attributable to or arise out of acts, omissions, or events of the Company or any other member of the Corporate Group which occur after the date of the execution of this Waiver and Release.
