Our Activities

Forerunner and Leader in GeoScience

In all environments, we acquire, process and interpret surveys that provide our clients with a comprehensive understanding of subsurface targets and their geological settings. We deliver our unique expertise in geoscience technology and project management through our three complementary business Divisions: Equipment, Acquisition and GGR (Geology, Geophysics & Reservoir).

On land, at sea or in the air, in remote regions and extreme climates or in urban areas, CGG serves its clients even in their most complex and ambitious projects. By providing them with the industry's most innovative technologies and the highest level of expertise available, we help our clients meet the energy and environmental challenges of today and tomorrow.


Our Equipment Division, with Sercel, designs, manufactures and markets a comprehensive range of innovative and reliable seismic systems and reservoir monitoring instruments. Oilfield service companies and geophysical contractors from across the globe use our equipment for seismic exploration and reservoir monitoring in onshore, offshore (streamers and ocean bottom equipment), transition zone and downhole environments.


CGG Marine


We help our clients image the most complex targets and delineate shallow hazards. Ours is one of the most high-end fleets, acquiring broadband, wide-azimuth, ultra-long offset, full-azimuth and 4D data. Single or multiple vessels deploy state-of-the-art BroadSeisTM or StagSeisTM acquisition technology.

CGG Land


Our surveys acquire seismic, gravity and magnetic data as well as properties such as target-based nearsurface resistivity. Projects span from massive Middle East operations in mature fields to small-scale environmental and hydrogeological site investigations. Reservoir monitoring services provide real-time input for enhanced production and risk mitigation. Seabed acquisition is conducted by Seabed Geosolutions BV, a joint venture with Fugro (owned 60% by Fugro and 40% by CGG).
