Description
The Jubarte 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. The survey is located in the northwest part of the Campos basin over the original BC-60 Round 0 block.
The Jubarte oil reservoir is located in the Maastrichtian interval approx. 1.3km beneath the sea floor.
