EMGS was in 2002 the first company to successfully apply marine CSEM technology to the search for hydrocarbons (see history). Since then, the Company have successfully commercialised the technology and turned it into an effective, environmentally benign exploration method that, when used correctly, can significantly increase drilling success rates.

EMGS, the marine EM market leader, uses its proprietary electromagnetic (EM) technology to support oil and gas companies in their search for offshore hydrocarbons. EMGS supports each stage in the workflow, from survey design and data acquisition to processing and interpretation. The company's services enable the integration of EM data with seismic and other geophysical and geological information to give exploration experts a clearer and more complete understanding of the subsurface. This improves exploration efficiency and reduces risks and the finding costs per barrel.
 
EMGS operates on a worldwide basis with main offices in Trondheim and Oslo, Norway; Houston, USA; and Kuala Lumpur, Malaysia.
