CGG : Anadarko Awards CGG the Largest Proprietary 3D Marine Seismic Survey in Colombia

Paris, France - March 19, 2015

CGG announced today that it has been awarded a contract by a subsidiary of Anadarko Petroleum Corporation to acquire and process a 16,314-km2 3D seismic survey on the Caribbean coast offshore Colombia. The survey will be the largest marine seismic program ever acquired in Colombia and follows CGG's successful completion of Anadarko's 5,500-km2 3D Fuerte survey offshore Colombia in 2013.

The survey, covering portions of the Col-1 and Col-2 blocks, will be acquired by the Oceanic Sirius and Oceanic Vega. These environmentally certified vessels are the flagships of CGG's seismic fleet. Each vessel will tow a 12 x 120 x 8,100 m spread using Sercel's Sentinel® steerable solid streamers and CGG's proprietary DovetailTM efficient acquisition solution designed to achieve more regular sampling and reduce infill. The survey will start in the second quarter of 2015, subject to regulatory approval. The survey data will be processed in CGG's Houston subsurface imaging center.

Jean-Georges Malcor, CEO, CGG, said: "We are very pleased to have been selected for this important contract, based on our advanced technology, the tight integration between our marine seismic acquisition and subsurface imaging groups and our deep in-country operational experience in Colombia. A project award of this magnitude underlines the confidence Anadarko has in our technology and expertise. We look forward to once again helping Anadarko reach its exploration goals in Colombia."
