Abstract

Magnetotelluric (MT) data can be particularly useful for delineating potential hydrocarbon traps (sediments which are conducting) below volcanic (which are resistive) which give rise to multiple reflection and scattering of seismic energy. The diffusive signal propagation used in MT can be an advantage in a region of intense heterogeneity while seismic signals will be scattered, the MT signals diffuse and give a reliable estimate of the physical property of the medium.
