This 3D survey covers the eastern part of the original block BC-400 assigned in Round 0. It is located in the central part of deepwater CamposBasin and is proximal to the production areas of Albacore (to the north) and Marlim Leste (to the southwest). Prospective targets are in the Cretaceous to early Tertiary period in sandstone and carbonate environments.
The data were reprocessed from public domain ANP data.
