Electromagnetic (EM) survey techniques can identify differences in the resistivity of subsurface rocks that can help discriminate between water and hydrocarbons, and reduce exploration risk. Marine EM surveys are conducted, using a towed electrical source and either towed or seabottom-based receivers. The sources are typically towed near the bottom in water depths greater than 500 m. However, new techniques allow towing within 10 m of the surface, in waters as shallow as 30 m.
IAGC study. In November 2011, the International Association of Geophysical Contractors (IAGC) announced the completion of an environmental impact assessment (EIA) of electromagnetic techniques used in oil and gas exploration, and production, in marine environments. The study was funded by the member companies of IAGC’s EM subcommittee and prepared by LGL Limited environmental research associates.
