In the offshore basin of Benin, some sediments of Albian age were identified. These sediments are gathered in formation named “Albian Formation”. At regionally scale, they are targeted for petroleum exploration and production. This paper aims to precise the petrographic and structural features of these sediments. Petrographic analyzes reveal the presence of two dominant facies (a main sandy facies and a shale facies which is thicker in deep offshore). Sandstones are very compact, gray to dark gray, and composed mainly of sharp and subrounded quartz grains of various sizes. Shales are massive, gray to blackish and friable to compact. Seismic sections interpretations show that Albian formation is generally continuous, of more or less constant thick and little varied lithological composition in East-West direction. In North-South direction, the formation gradually thick towards the offshore and become significantly reduced in very deep water. The formation is affected by normal and combined faults as well as by reverse faults of NE-SW and NW-SE trends. Structural traps of hydrocarbons are more present in shallow deep offshore while, in deep offshore, traps are essentially of stratigraphic type.
