Nowadays, the identification and exploitation of hydrocarbon reservoirs poses ever-increasing challenges. These include the search for hidden reservoirs beneath saline horizons or extensive basaltic flows, as well as the application of improved stimulation methods for the recovery of residual hydrocarbons in reservoirs.
Current strategies for interpreting seismic sections and cubes seek not only to detect structures in greater detail but also to discern the characteristics of both the porous matrix and the different fluids contained within it. To address these new challenges, it is necessary to integrate different types of geophysical information that complement the images obtained from reflection seismic data, such as geophysical logs, electromagnetic data, and even gravity and magnetic data. This information is then applied using modern joint inversion techniques.
At GGI we have the capabilities to assimilate various types of geophysical data and adjust them to structures identified by seismic sections and cubes. We also seek to increase depth resolution by using well information, jointly inverting cross-hole tomography (seismic or electromagnetic) data and geophysical logs.
