Abstract
Controlled Source Electromagnetic-Marine (CSEM) Method is a very powerful technique in deciphering whether the reservoirs are hydrocarbon or water saturated. Hence, to reduce the risk in deep water areas CSEM is employed to detect the resistive hydrocarbon reservoirs. This paper discusses about the various 1D Marine CSEM responses due to the presence of subsurface resistive bodies since hydrocarbon saturated reservoirs are 10-100 times more resistive than the overlying sediments.
