In accordance with structural development, the stratigraphic succession of this basin was divided into 4 sequences: pre-rift (up to Late Jurassic); rift (Neocomian to Lower Cretaceous); transitional (Cenomanian to Santonian) and post-rift (Maastrichtian-Holocene) sequences. Only one Upper Cretaceous petroleum system is well known within this basin. Source rocks of this system contain Type II-III kerogens with a TOC (Total Organic Carbon) average of 2.9%. Oil is produced from sandstone facies within Abeokuta formation. Currently exploration data and geochemical characteristics of bituminous sands which outcrop in some onshore areas of the Dahomey Embayment point to the existence of another petroleum system of Lower Cretaceous age (Neocomian to Albian) in this basin.
