Paris, France - April 4th 2013

CGG announced today that its new fleet, with the addition of four high-end vessels from its recent
acquisition of Fugro Geoscience, set two new industry records that highlight the strength of its
marine capabilities.

The longest offsets in the industry for a full-azimuth (FAZ) multi-vessel survey

Firstly, through its proprietary ground-breaking StagSeisTM survey configuration, CGG can claim
the record for deploying the longest offsets in the industry for a full-azimuth (FAZ) multi-vessel
survey. For the recent multi-client 'IBALT' survey in the Gulf of Mexico, offsets were a
record-breaking 18km.

StagSeisTM data are acquired using multiple vessels with an innovative staggered configuration,
developed to provide the ultra-long offsets, full-azimuth and broad bandwidth (especially low
frequencies) required to face the challenges of imaging in complex areas such as the Gulf of
Mexico. As the data are acquired in a regular grid, processing is compatible with conventional
wide-azimuth techniques, allowing faster turnaround than alternative non-linear methods.

The largest single-vessel acquisition footprint in the world

Secondly, the Geo Caribbean operating in the Gulf of Mexico can claim the title of the largest
man-made moving object on the face of the earth, with its record-breaking 13.44 km2 towing

The challenge was to design a configuration that would enable the client to meet its survey
objectives in a cost-effective and efficient manner, while also achieving the survey's geological
objectives. CGG proposed a wide tow of eight streamers with a 160-m separation, 60% wider than a
typical survey with a 100-m separation, enabling a greater area of data to be acquired in a single
pass and hence greater production efficiency. By deploying a streamer length of 12000m, CGG
delivered the long offsets required to achieve the survey's geological objectives. The end-result
is an efficient survey design and the largest single-vessel acquisition footprint in the world. 

Jean-Georges Malcor, CEO, CGG, said: "These impressive achievements by our marine fleet are
further examples of our continuing commitment to innovation and our pioneering role within our
industry. With the addition of Fugro's C-class vessels to our recently upgraded fleet, we now have
the largest seismic fleet of modern high-end vessels bringing the benefits of innovative
illumination solutions to our clients."
