Abstract

Summary

We have successfully helped to introduce the magnetotelluric (MT) method in the workflow for the exploration of oil&gas in Brazil and strongly suggest that the MT method can be used in the frontier onshore areas of East Africa. The MT method is used to uncover the potential of frontier onshore basins and also to delineate prospects in the mature basins. The MT method is a powerful frequency domain electromagnetic technique that provides a resistivity model of the subsurface of the earth at depth. MT data acquisition is fast, environmentally friendly and provides the structural and stratigraphic information needed to explore onshore basins. In recent years, the magnetotelluirc (MT) method was considered by the National Petroleum Agency (ANP) of Brazil as a valuable exploration tool and was added to the list of methods that account for the Exploratory Program (PEM).
