Abstract

Geo-magnetic modeling and potential hydrocarbon traps over the Gongola basin was carried out using the high-resolution aeromagnetic data utilizing the Oasis MontajTM software, total magnetic intensity map was done and potential hydrocarbon traps as well as modeling were carried out from the residual map. GM-SYS module of the Oasis montaj was used for this study, depocentres (grabens) that may serve as hydrocarbon traps were delineated, as well as basement configuration were determined. The models reveal the horst and graben architecture of the basement and the various faults that segmented the area into block patterns as well as the rifting nature of the Benue trough. The results showed that the models have sediment thickness in the range of 5 km and above which is in agreement with the results obtained by current oil exploration in the area. The points A, B, C, D, E, F, G, H and I are considered as areas of magnetic low’ or weak anomalies, and are recognized as potential hydrocarbon traps or a local relief on the basement surface.
