Petrobras, declares that the consortium formed by Petrobras (45% - operator), BG Group (30%), and Repsol YPF (25%), to explore block BM-S-9, located in ultradeep waters of Santos Basin, proved the existence of another light oil accumulation, with specific gravity around 28º API, in pre-salt reservoirs.

Block BM-S-9 is composed of two exploratory areas. In the largest part was drilled the well 1- BRSA-491-SPS (1-SPS-50), known as Carioca, which resulted in the discovery announced on September 5, 2007. The Assessment Plan for this area was recently approved by the ANP.

The new well, called 1-BRSA-594-SPS (1-SPS-55), known as Guará, is located in the smaller area of the block, at some 310 km off the coast of the State of São and at 2,141 meters of water depth. The well is still being drilled in search of deeper prospects.

The discovery was proved by an oil sample collected via a cable test carried out in reservoirs situated at a depth of nearly 5,000 meters.

After well completion, the Consortium will proceed with the required activities and make the investments that are needed to verify both the field’s dimensions and the characteristics of the oil reservoirs by forwarding an Assessment Plan to the ANP, as provided for in the Concession Agreement.
