Petrobras discovers more oil in Campos Basin
With the drilling of a single well (6-BR-63A-RJS) Petrobras has discovered two new oil accumulations in reservoirs located in the Campos Basin, one in post-salt and the other in a pre-salt region.
The exploratory well was drilled in the Barracuda production concession area, some 100 km off the coast of the State of Rio de Janeiro, at a water depth of 860 m. The company already has production and offloading infrastructure installed in the area.
Pre-salt region
One of the accumulations that was discovered was in pre-salt carbonatic reservoirs and is nestled at a depth of 4340 m. Preliminary estimates indicate the presence of light oil (28° API), with recoverable volumes of approximately 40 million bbls in reservoirs of good productivity.
Post-salt region
The other discovery, also in well 6-BR-63A-RJS, was an oil accumulation found in sandy post-salt reservoirs, which already have a production history in the Barracuda area. The volume of recoverable oil has been estimated at 25 million bbls in this accumulation.
Taking advantage of the complete production and outflow infrastructure installed in the area, the company is look into interconnecting well 6-BR-63A-RJS to Platform P-43, which is already in operation at the Barracuda field.
