This 3D survey covers all of BC-600, a Round 0 block and extends eastward to the original BM-C-18 block. It encompasses the deepwater area of central Campos Basin. Prospective carbonates, cretaceous (light oil) and tertiary turbidites (heavy oil) are the potential targets. The Roncador (cretaceous sands) and Frade (tertiary turbidites) production areas are on the west flank of the survey, Albacora Leste to the southwest.
