Description
The Golfinho HD3D is a 4D baseline survey designed to repeatedly illuminate the produced and unswept areas of the reservoirs to extend the production life of the field which is located in >1,320 m water depth. The survey is located in the original Round 0 block, BES-100.
The Golfinho reservoir is producing both oil and gas from a sandstone in the Miocene interval approximately 3.4 km beneath the sea floor.
