The French company will have 49% of Arctic Geophysical Exploration (AGE), with SCF holding the rest.
The company will conduct 3D surveys, mainly in Arctic and sub-Arctic waters.
AGE will be based in Moscow.
CGG will charter a fourteen-streamer ice-class vessel, while Sovcomflot will add an eight-streamer ice-class vessel.
AGE will have a total fleet of four ships.
SCF CEO Sergey Frank 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.”
