           Schlumberger to Sell SchlumbergerSema Businesses

  Strengthens Focus on Oilfield Services and Exploration & Production
                   Process and Information Solutions

Schlumberger Limited (NYSE:SLB) announced today the signing of a
binding agreement with Atos Origin for the sale of the majority of
SchlumbergerSema businesses.

The transaction proceeds would amount to approximately $1.5 billion
consisting of EUR400 million in cash and a fixed number of 19.3
million of Atos Origin common shares that represent approximately 29%
of the common shares outstanding of Atos Origin. Subsequent to
closing, Schlumberger expects to reduce its ownership in Atos Origin
to 19% following which Schlumberger intends to account for this
investment under the cost method. The closing, which is expected in
January 2004, is subject to Atos Origin shareholder approval,
customary regulatory approvals, the employee information and
consultation process, and other conditions. Using the Atos Origin
stock price and US dollar Euro exchange rate as of Friday, September
19th, Schlumberger expects no impairment charge to earnings for the
third quarter as a result of this transaction, though facts and market
conditions could alter this conclusion for this quarter and future
reporting periods.

Commenting on this transaction, Andrew Gould, Chairman and Chief
Executive Officer, said:

"The future for Schlumberger services to the upstream oil and gas
industry is exceptionally bright as the world adds new supply capacity
to meet demand and replace production from aging hydrocarbon
reservoirs. Key amongst the techniques required to enhance hydrocarbon
recovery will be the information technologies that enable real-time
reservoir description, monitoring and management.

Schlumberger has the fundamental IT knowledge needed and will address
these opportunities through the expanded Schlumberger Information
Solutions operating unit that is part of Schlumberger Oilfield
Services. The activities of this unit include technical consulting,
information management and Exploration & Production (E&P) software
augmented by E&P business process optimization together with secure
worldwide network connectivity from sub-surface to desktop."

Gould further stated:

"The global IT services industry is going through an important phase
of consolidation and the combination of the SchlumbergerSema IT
businesses with Atos Origin will create a leading European IT Services
company with broad presence and competence across the world."

Schlumberger will retain a number of specific SchlumbergerSema
businesses that include Business Continuity, Infodata - a Swedish
database company - and all software products related to the
SchlumbergerSema telecommunications activity. These, together with
smart cards, point-of-sale terminals, payment systems, eCity terminals
and payphones are being considered for divestiture or IPO.

Schlumberger Limited also announced charges to be taken in the third
quarter.

As previously announced, the company will record the second and final
after-tax charge of $86 million, which includes premium, issuing and
tender costs related to extinguishment of European debt.

In the light of current and expected future business conditions in the
seismic sector, the company has undertaken and completed an impairment
review of the WesternGeco multiclient library. As a result,
WesternGeco will record a pre-tax charge of $398 million. Schlumberger
will recognize an after-tax and minority interest charge of $205
million in the third quarter. Approximately 70% of the charge relates
to North American surveys.

                                  ###
