Petrobras has confirmed the presence of good quality oil (31 º API) in ultra deep waters of Santos Basin pre-salt while drilling well 1-SPS-98 (1-BRSA-1063-SPS), informally known as Sagitário. This is the first well to be drilled in block BM-S-50 and is located 194 km off the coast of São Paulo state, at a water depth of 1,871 meters.

The concession were this well is being drilled is located west of the main discoveries of the Santos Basin pre-salt (cluster blocks). The importance of this discovery lies on the fact that this is an exploratory frontier.

The oil was found in carbonate reservoirs below the salt layer at a depth of 6,150 meters. The well is still in the drilling phase, which is set to continue until the planned depth of 6,950 meters, with the aim of defining the base of the oil reservoirs.

Petrobras is the operator of the consortium (60%) in partnership with BG E&P Brasil (20%) and Repsol Sinopec Brasil (20%).
