Description
EM surveys involve transmitting electromagnetic waves into the ground and measuring the induced electrical currents. Hydrocarbon-bearing formations typically exhibit resistive properties, contrasting with conductive saline water zones. CSEM is widely used in offshore exploration, where a transmitter tows an electric field over the seafloor, detecting resistive hydrocarbon accumulations. Magnetotelluric (MT) methods use natural variations in the Earth’s magnetic field to probe deep subsurface conductivity. Resistivity methods involve passing electrical currents through the ground and analyzing resistivity variations, useful for delineating reservoir boundaries. Advances in inversion modeling and machine learning enhance interpretation accuracy.
