Cameron and Schlumberger Form Subsea Joint Venture

Cameron and Schlumberger today announced the creation of OneSubsea?, a
joint venture to manufacture and develop products, systems and services
for the subsea oil and gas market. This new company will offer a step
change in reservoir recovery for the subsea oil and gas industry through
integration and optimization of the entire production system over the
life of the field. The integration of the production system will be
accomplished by combining superior reservoir knowledge and wellbore
technologies, with industry leading subsea technologies, all together
delivering enhanced productivity, reliability and integrity.

Cameron and Schlumberger have 60/40 ownership of the joint venture,
respectively, and the transaction is subject to regulatory approvals and
other customary closing conditions. Cameron, with its long history of
innovation and firsts in the subsea market, is an industry leader in
design capability, manufacturing excellence and successful
installations. Schlumberger brings a deep understanding of the
reservoir, and industry-leading well completions, subsea processing and
integration platform.

Under the terms of the formation agreement, Cameron will contribute its
existing subsea division and receive $600 million from Schlumberger.
Schlumberger will contribute its Framo, Surveillance, Flow Assurance and
Power and Controls businesses. Cameron will manage the joint venture and
will consolidate it for financial reporting purposes. Cameron will
reflect minority interest in its financial statements for Schlumberger′s
interest in the JV.

Cameron Chairman, President and CEO, Jack B. Moore said, 'Our new
venture with Schlumberger provides a powerful marriage of their oilfield
services technology and our subsea equipment heritage. It leverages
Cameron′s flow control expertise, world class manufacturing and
aftermarket capabilities.?

Schlumberger CEO Paal Kibsgaard commented, 'This new joint venture,
which combines the forces of two world-class companies, is uniquely
positioned to optimize complete subsea production systems and help our
customers improve production and recovery from their subsea
developments. The broad scientific and technology platform that
Schlumberger brings will enable a total system approach, leading to a
unique and differentiated offering in this rapidly growing market.?

A key priority of the joint venture will be strengthening research and
engineering investment, including complementary projects with the parent
companies, towards the integration of the complete subsea production
system from pore space to the export point, in order to unlock reservoir
potential from our customer′s subsea developments.
