The airborne magnetic data is considered as one of the best methods to delineate the depth to basement layer. Data is accurately processed, interpreted and three-dimension inversion of the RTP data was performed to generate 3D basement relief contour map. After creating the 3D basement relief map, the sedimentary succession of the study area is created using seismic data and well data. These data are obtained from different published sources and used in building the model using petrel software. The results of the 3-D model confirmed that the area is very promising for hydrocarbon accumulation, and also new hydrocarbon accumulations have been discovered.
