Controlled source electro-magnetic

energy

The controlled source electromagnetic method, also called sea bed logging, is a mostly offshore geophysical technique, employing electromagnetic remote-sensing technology to map the electric resistivity distribution of the subsurface. The electrical resistivity helps to discriminate between different types of rocks and to indicate the presence and extent of hydrocarbon below the seabed.
