The electromagnetic (EM) method uses electromagnetic energy to map the resistivity distribution, such as those associated with hydrocarbon reservoirs, beneath the seabed.
Unlike seismic surveys, which use acoustic energy to locate promising geological structures, resistivity is directly influenced by the presence of hydrocarbons. Where seimic methods generally indicate the presence of a suitable structure, EM data improves confidence in ranking the prospect with respect to hydrocarbon prospectivity.
Fugro can offer expertise in every phase of marine EM workflow from feasibility studies, acquisition, QC, processing, interpretation, to integration with other geophysical and geological data such as seismic, seismic inversion, gravity, magnetics, rock-physics and well information.
