Magnetic Modeling and Potential Hydrocarbon Trap Over Yola and Environs Upper Benue Trough Northeastern Nigeria

Abstract

With a renewed interest to search for hydrocarbons in the hinter land of Nigeria’s inland basin climaxed after the discovery of a rewarding oil prospects around the Kolmani river II as recently announced by the National Oil Company, the Nigeria National Petroleum Corporation (NNPC). This research was based on analyzing the high-resolution aeromagnetic data over the study area using the Oasis Montaj TM software, in order to get the total magnetic intensity map as well as the residual map, band pass filter map was used to generate magnetic aureoles. GM-SYS module of the Oasis montaj was used for the modeling exercise, the models reveal the horst and graben architecture of the basement with the grabens serving as depocentres, hydrocarbon potentials of the area were highlighted using magnetic aureoles mapping.
