Next Generation CSEM Equipment Field Test. A demonstration / pilot project of the next generation CSEM technology prototype.

Electromagnetic Geoservices ASA, with assistance from project partners, is developing the next generation of controlled-source electromagnetic (CSEM) surveying technology. This technology is based on remote resistivity measurement. Using receivers placed on the seabed and a source towed just above the sea bed, sensors in the receivers detect the varying electromagnetic resistivity of the subsurface which is used by oil companies to improve their probability of drilling success and to update their volumetric estimations of potential hydrocarbon deposits. The next generation technology will improve subsurface penetration and improve the resolution of the final resistivity images & volumes, through improvements in signal to noise ratio and reduction of positioning uncertainties. This can change the way that oil and gas companies manage their exploration process. Current workflows rely on seismic which gives mainly structural information. Electromagnetic technology fills in missing parts of the exploration puzzle, it adds information about whether structures are likely to contain hydrocarbons, and whether they are sealed within the structure or have leaked out. This technology can, and does, change exploration drilling success rates.
