What is EM imaging?
EM imaging uses electromagnetic energy to detect resistive bodies, including hydrocarbon reservoirs, beneath the seabed.
Unlike seismic surveys, which use acoustic energy to locate promising geological structures, EM imaging can reveal the presence of commercial hydrocarbon reserves. EM imaging can identify reservoirs before seismic surveys are conducted. Where seismic methods indicate the presence of a suitable structure, EM data dramatically improves confidence in ranking the prospect. And EM has the potential to find hydrocarbons in traps that cannot be detected using seismic methods and would be overlooked by conventional workflows.
EM imaging is applied at all stages in the life of field; to improve exploration efficiency in the world's frontier basins, appraise and delineate proven reservoirs, and re-evaluate mature basins. It also has potential to be used for monitoring reservoirs in producing fields.
