CGG : and Sovcomflot Announce Arctic 3D Seismic Joint Venture

Paris, France - 19 June, 2014

CGG, world leader in Geoscience, and Sovcomflot, Russia's largest energy shipping company, announced today that they have signed an agreement to form a joint venture company dedicated to conducting high-end 3D marine seismic acquisition services with a focus on Arctic and sub-Arctic waters.

The joint venture, to be called Arctic Geophysical Exploration (AGE), will be 51 per cent owned by Sovcomflot and 49 per cent owned by CGG. The company will be incorporated in Russia with its headquarters in Moscow. Under the terms of the agreement, CGG will charter a fourteen-streamer ice-class vessel while Sovcomflot will add the capabilities of an eight-streamer ice-class vessel.

The primary aim of the joint venture company is to offer world-class 3D marine seismic acquisition services to operators during the Arctic navigation season. In addition, the new company will offer its highly advanced vessel capabilities to the international market for the remainder of the year while benefiting from access to the most advanced seismic technologies from CGG's worldwide operational and technical support.

CGG and Sovcomflot will have a combined total of four vessels scheduled to operate on client projects during the 2014 Arctic navigation season and expect the joint venture to be fully operational by Q4 2014 in order to capture the growing 3D seismic market in this region.

Jean-Georges Malcor, CEO, CGG, said: "The Russian Arctic is an exciting new frontier that has increasingly shown its potential over the last two years. By bringing together the two companies' strong HSE cultures, Sovcomflot's considerable Arctic maritime experience and Russian presence along with CGG's expertise as a leading technology provider, we believe this joint venture will create a strong vehicle for growth in this demanding region."

Sergey Frank, President & CEO, OAO Sovcomflot, said: "By combining Sovcomflot's in-depth knowledge and experience of operating in the Arctic with CGG's global expertise in marine seismic operations, we have created a powerful new Russian marine seismic company able to meet the most demanding technical and operational challenges of the Arctic region, whilst also being able to offer a competitive range of seismic services internationally."
