In this study, we presented a new multi transient electromagnetic (MTEM) data acquisition array to solve the challenges observed in using the conventional data acquisition setup in MTEM survey over complex geology. This involves the use of double transmitter dipoles and the recording of both the forward and reverse responses. The result obtained from using the dense reverse source (DRS) array to reconstruct the subsurface resistivity distribution over part of Anambra basin shows that the new method is more effective in mapping non horizontal hydrocarbon filled reservoir and very useful for general geophysical prospecting.
