Petrobras Makes Santos Basin Pre-Salt Discovery

A Petrobras-led consortium has proved the presence of oil in pre-salt reservoirs with well 1-BRSA-532A-SPS (1-SPS-52A). Preliminary analyses indicate oil gravity is between 25 and 28 API, comparable to that of the other pre-salt oils found in the Santos Basin. The well is located in an ultra-deepwater area of the Santos Basin.

This pioneer well is located approximately 250 kilometers off the coast of the state of Sao Paulo in 2,139 meters of water. It was completed on May 18, 2008 at a depth of 6,773 meters and was drilled by the Noble Paul Wolff semisub.

The discovery was proved via an oil sampling by a lined well formation test in reservoirs situated at a depth of nearly 6,000 meters.

The Consortium is preparing a Discovery Assessment Plan to be sent to the ANP, as provided for in the Concession Agreement, giving continuity to the investment activities for block BM-S-8.

Partners in the Consortium are Petrobras as operator with 66%; Shell with 20% and Galp energia with 14%.
