Paris, France - April 11, 2013

CGG announced today that three acquisition crews operating in Saudi Arabia on behalf of Saudi
Aramco have achieved impressive safety records. Two OBC crews have completed six million and five
million man-hours of continuous operations without a Lost Time Incident (LTI) respectively while a
third vibroseis crew has crossed the milestone of seven million man-hours of continuous operations
without LTI. All three crews are operated by ARGAS, CGG's joint venture with TAQA in Saudi Arabia.

OBC crew S66 has been working in the Arabian Gulf for over two and a half years while OBC crew S65
also worked in that region for over two years. Both crews have achieved outstanding airgun
production rates while recording four-component data with the Sercel SeaRay(R) seabed acquisition
system. Each crew deploys 250 people and 8-10 vessels in areas that are congested with production
fields, pipelines and vessel routes. Vibroseis crew S61, mobilizing 875 people, has been operating
for the last three and a half years in desert areas in extreme weather conditions.  

Jean-Georges Malcor, CEO, CGG, said: "These excellent safety performances by our Saudi crews in
challenging operating conditions are testimony to the high level of commitment shown by the
management teams of both ARGAS and Saudi Aramco as well as the day-to-day dedication of all the
field and support staff."
