Evaluation of basement topography and structures in the Dahomey Basin and surrounding environs of Southwestern Nigeria, using satellite gravity data

Attempts at regional gravity studies of the southwest Nigerian geologic terrain have been limited due to sparse distribution stations and prohibitive costs measurements. The use satellite-based global data provides a reliable cost-effective means regional-scale studies, WGM2012 was employed evaluate basement topography structures. aim work is map regions in sector Dahomey Basin with suitable sediments thickness fracture systems, capable hydrocarbon generation preservation. Bouguer anomaly subjected series processing enhancement, using Oasis Montaj software. Observations distributions reveal division study area into three zones, namely, terrain, Niger Delta Basin. structures trend general north–south directions, but approximate orientations vary significantly, abundance sub-parallel discordant alignments. depths range from <2000 >5000 m, being deepest part area. results establish as containing minimum required sedimentary 3000 m necessary for accumulation.
