New Oil Accumulation Discovered in the Santos Basin Pre-Salt Layer

The consortium formed by Petrobras (66%, operator), Shell (20%), and Galp Energia (14%), has proved the presence of oil in pre-salt reservoirs, in block BM-S-8, in ultra-deep waters in the Santos Basin, after drilling well 1-BRSA-532A-SPS (1-SPS-52A). Preliminary analyses indicate oil gravity is between 25 and 28 ºAPI, comparable to that of the other pre-salt oils found in the Santos Basin.

This pioneer well is located some 250 km off the coast of the state of São Paulo, at 2,139 m from the water line. Drilling was completed on May 18, at a depth of 6,773 meters and the discovery was proved via an oil sampling by means of a 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 NPA, as provided for in the Concession Agreement, giving continuity to the investment activities for block BM-S-8.
