Petrobras has announced the finding of another oil and gas field in the pre-salt reservoir of block BM-S-9, in ultra-deep Santos Basin waters. The discovery was made via well 4-SPS-66C (4-BRSA-723C), called Abaré Oeste, located in the assessment area of 1-SPS-50 (Carioca), some 290 km off the coast of the state of São Paulo, 2,163 m from the water line. This is the fourth well drilled in block BM-S-9. All of them proved the existence of hydrocarbons.
Block BM-S-9 is comprised of two assessment areas, the area of the Guará well and the area of the Carioca well.
The discovery was proved by means of a sampling made from reservoirs located at a depth of approximately 5,150 m. Further analyses are being made with the samples for a better characterization of the oil that was found.
