Abstract

Hydrocarbon exploration in Bornu basin, Northeastern Nigeria commenced due to the discovery of gigantic hydrocarbon reserves in extended basins in neighboring countries. This study was carried out to map the Mungono and Marte parts of the Bornu basin for geologic structures that could guide in exploring new hydrocarbon fields using aeromagnetic method. Magnetic Intensity grids and their derivatives were used for mapping these structures while depths of magnetic sources (basement) and corresponding sedimentary thickness were estimated using Euler deconvolution and Source Parameter Imaging (SPI) methods. Anomalies show characteristic high positive polarity in the south in contrast to low magnetic signature of northern domain. Features such as faults, folds and intrusive rock bodies were identified as geological structures that could serve as hydrocarbon entrapment. Lineament analysis shows that fractures generally trend NE-SW following the dominant rift system of Bornu basin and Benue Trough. Three basement depressions with thick sediments (more than 3000 m) were also delineated which should be investigated for further petroleum exploration. The outcome of this study would help in delineating promising areas for detail hydrocarbon prospecting in the area.
