GEOSYSTEM - R & D

The focus of our activity for the oil industry is to provide cost-effective geophysical solutions in typically hostile environments such those characterized by complex thrust belt tectonics, shallow volcanics, outcropping carbonates, or sub-salt.
In such environments the conventional seismic methods often provide marginal results and new exploration approaches need to be defined.

To MT, the conditions which cause difficult seismic energy propagation are largely irrelevant and thus the method readily images the sub-surface in terms of resistivity. Ideal targets include resistive carbonate reservoirs below shale or flysch, clastic reservoirs below salt bodies, and so on.

Extended-offset seismic acquisition geometries followed by wide-offset imaging and tomographic velocity determination provide the key to a successful imaging of complex areas.
This is achieved by an enhanced S/N ratios of long-offset reflected events and more robust velocity analysis.

Integration of Seismics, Gravity and MT leads to improved velocity model building for outcropping carbonates, thrust sheets, sub-basalt and sub-salt for seismic imaging, and to better resistivities estimates for MT interpretation. The integration process is performed by Joint Inversion for multiparametric models or on an interactive basis.
