Interpretation of Marine CSEM and Marine MT Data for Hydrocarbon Prospecting

Remote sensing techniques record variations in petrophysical parameters such as acoustic or electric properties. Seismic sounding is by far the most common of such tools. Seismic techniques can detect strata and structure in the subsurface that are potential hydrocarbon (HC) traps. By interpreting the seismic a detailed geological model can be constructed, but seismic data has limitations in direct prediction of pore fluid composition. Given detection of a structural geometry that may contain HC within porous sedimentary rocks, the main remaining uncertainty is normally whether the pore space is filled with saline water or HC. For this reason only 10–30% of exploration wells penetrate commercial oil or gas reserves in many areas.
