Marine controlled-source electromagnetic (CSEM) and magnetotelluric (MT) data can be interpreted to provide estimates of resistivity distribution in the subsurface. However, such measurements are complementary to those obtained from more conventional seismic methods, and are thus most powerful when placed in an integrated interpretation framework. For example, whereas seismic data can provide detailed images of the geologic structure and stratigraphy, determining fluid properties within intervals of interest can be challenging, or in some cases, impossible. CSEM-derived resistivity measurements are more sensitive to fluid saturation, but may be ambiguous when interpreted in isolation: resistivity variations resulting from changes in lithology or...
