Exhibit 10.3

SCHLUMBERGER LIMITED

RESTORATION SAVINGS PLAN

(As Amended and Restated Effective January 1, 2008)

First Amendment

Schlumberger Limited, a Curacao corporation (the “Company”), having reserved the
right under Section 8.02 of the Schlumberger Limited Restoration Savings Plan,
as amended and restated effective January 1, 2008, and as thereafter amended
(the “Plan”), to amend the Plan, does hereby amend the Plan, effective
January 1, 2013, as follows:

1. Section 2.01 of the Plan is hereby amended in its entirety to read as
follows:

“2.01 Employer Determination

Each year, prior to the last day of the Enrollment Period, the Employer shall
determine those Eligible Employees who may participate in the Plan during the
subsequent Plan Year. Such determination shall be made in accordance with the
requirements set forth in Section 2.02. The Employer may also designate
Employees who are newly hired or are transferred to the Employer (each, an
‘Initial Eligibility Event’) as Eligible Employees regardless of the timing of
such Initial Eligibility Event.”

2. Section 2.02 of the Plan is hereby amended to add the following paragraph
after the first paragraph of such section:

“Subject to Section 4.01, an Employee initially designated as an Eligible
Employee during a Plan Year who is projected to have Excess Compensation during
such Plan Year may elect to defer Base Compensation that is also Excess
Compensation. Such election shall remain in effect until the first day of the
Plan Year following the end of the next Enrollment Period to occur after the
Employee’s designation as an Eligible Employee.”

3. Section 3.01 of the Plan is hereby amended to add the following sentence to
the end of such section:

“Notwithstanding the above, and subject to Section 4.01, an Employee initially
designated as an Eligible Employee during a Plan Year may make a deferral
election within 30 days following the date such Employee is initially designated
as an Eligible Employee. Such election shall remain in effect until the first
day of the Plan Year following the next Enrollment Period.”

--------------------------------------------------------------------------------

4. The first sentence of Section 4.01 of the Plan is hereby amended to read as
follows:

“Effective for Elective Deferrals occurring after the June 2012 Enrollment
Period, an Eligible Employee may irrevocably elect to defer, in any whole
percentage, an amount from 1% to 50% of such Eligible Employee’s Excess
Compensation.”

5. Section 4.01 of the Plan is hereby amended to add the following paragraph to
the end of such section:

“An Employee who becomes an Eligible Employee on or prior to the last day of the
Enrollment Period may also make an election to defer, up to the limits set forth
above, Base Compensation that is also Excess Compensation for the remainder of
the Plan Year. An Employee who becomes an Eligible Employee after the last day
of the Enrollment Period may make an election to defer, up to the limits set
forth above: (i) Base Compensation that is also Excess Compensation earned for
the remainder of the Plan Year and (ii) Base Compensation that is also Excess
Compensation earned in the next following Plan Year. For purposes of clarity, an
Employee’s deferral election shall remain in effect until the first day of the
Plan Year following the next Enrollment Period to occur after the Employee’s
designation as an Eligible Employee.”

6. Section 4.02 of the Plan is hereby amended to read as follows:

“4.02 Matching Contributions. Each year the Employer shall determine the
Matching Contribution.

Effective January 1, 2013, for Participants who were hired prior to October 1,
2004 and for Participants who did not elect to cease participation in the
Qualified Defined Benefit Plans effective January 1, 2005, the Matching
Contribution shall be equal to 50% of the first 6% of each participant’s
Elective Deferrals made during the Plan Year. Such contributions shall be made
by the Employer as soon as administratively practicable following each payroll
period.

Effective January 1, 2013, for Participants who were hired on or after
October 1, 2004 and for Participants who elected to cease participation in the
Qualified Defined Benefit Plans effective January 1, 2005, the Matching
Contribution shall be equal to 100% of the first 6% of each participant’s
Elective Deferrals made during the Plan Year. Such contributions shall be made
by the Employer as soon as administratively practicable following each payroll
period.”

7. Section 5.01 of the Plan is hereby amended to read as follows:

“5.01 Allocation of Elective Deferrals. As of each pay period, the Employer
shall allocate the Elective Deferrals made during such pay period to a
Participant’s Account.”

“5.02 Allocation of Matching Contributions. As of each pay period, the Employer
shall allocate the Matching Contributions, if any, among the Accounts of
Participants or Former Participants who made Elective Deferrals during the such
pay period.”
