This 3D survey covers most of BC-400, all of the BM-C-3 and the western part of BC-500, all originally Round 0 blocks. It encompasses the deepwater area of south-central Campos Basin. Prospective carbonate, cretaceous sands and tertiary turbidites are the potential targets with light oil discoveries being proximate. The Marlim Sul, Albacora and Albacore Leste production areas are to the immediate west.
