Consist in the register of the magnetic fields of the rocks, having the Earth magnetic field as reference. These fields are register by a magnetometer installed in a plane that flies over the interest zone. The sedimentaries formation that presents hydrocarbons doesn’t manifests [[magnetics]] properties.
