This 3D survey covers part of original block BMC-25, an original Round 4 block. It encompasses the outboard area of the shelf slope in the border between the southeast part of EspíritoSantoBasin and northwest part of CamposBasin. It is located north of the BC-10 discoveries and to the northeast of the Jubarte field. Potential targets range from Neocomian to early Tertiary in sandstone, calcarenite or carbonate environments.
The data were reprocessed from public domain ANP data.
