Gravity & Magnetics

MPMC Header

CGG houses the most comprehensive, privately-owned, multi-client airborne, land and marine potential fields geophysical database in the world. The database incorporates approximately 14,000,000 line kilometers of aeromagnetic data, 1,200,000 line kilometers of marine gravity & magnetic data, and 2,000,000 stations of land gravity data worldwide. Data may be licensed for entire surveys or for specific areas of interest.

Magnetic and gravity data provide a set of tools for general planning, large-scale basin-wide studies and prospect-scale analysis. The integration of gravity and magnetic data into the exploration program provides an opportunity for confirming or questioning existing interpretations. Gravity and magnetic methods can assist in tectonics and structural mapping, depth-to-basement, identification of salt diapirs, identification of volcanics, determination of sediment thickness, delineation of sediment fairways, and the mapping of intra-sedimentary anomalies. Gravity and magnetic data can assist in seismic modeling and in the determination of seismic processing parameters. Gravity and magnetic data can reduce exploration risk and can help you find oil and gas.
