Re-examination of traditional EM techniques for onshore hydrocarbon exploration

We investigate the feasibility of onshore hydrocarbon mapping using conventional resistivity methods. Three-dimensional modelling studies show, that standard methods such as DC-IP, CSAMT or LOTEM can sense a two by two kilometre reservoir at depths up to 1500 meter. If field noise levels are favourable, then well established EM methods (in acquisition and interpretation) could provide necessary information and consequently respected contractors may be used to de-risk terrestrial hydrocarbon licenses.
