EMGS - Technology

Technology

Marine EM, or CSEM (controlled source electromagnetics), is an emerging exploration method that uses electromagnetic energy to detect resistive bodies - including hydrocarbon reservoirs - beneath the seabed.

The power of data integration: EM responses match results from resistivity logs and seismic sections. Troll Field, Norway.

Because marine EM relies on contrasts in resistivity, it has the power to indicate hydrocarbon accumulations. This means it is a perfect partner for seismic data, which provide a structural picture of the subsurface.
