This 3D survey covers the original Round 6 blocks BM-CAL-7, 8, 9, 10, 11 & 12. It encompasses the shallow water area in the north part of the program out to the deepwater in the eastern part of the program. The survey is located in the central and southern part of the Camamu-AlmadaBasin. Prospective tertiary turbidites and cretaceous sands are potential targets.
