Controlled source electro-magnetic
text:
The controlled source electromagnetic (CSEM) 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. CSEM is mostly used to indicate the presence and extent of hydrocarbon below the seabed. The CSEM survey uses a dipole source that is towed just above the seafloor to transmit
