oa New Seabed Cable Technology for EM and Seismic Applications

A new exploration technology has been developed which combines the strengths of both seabed seismic and EM sensing into a single seafloor cable to locate and identify the content of hydrocarbon reservoirs. While conventional seismic methods offer the best means to map the sub-surface structural geometry, EM waves have the ability to identify reservoir fluids better than seismic P-waves. Therefore EM data acquired in combination with seafloor seismic (P- and S-waves) are considered the best way of determining hydrocarbon probability. The technology was first tested out in the Sognefjord and extensive field trials were performed in 2008 over the North Sea Peon discovery.
