Petrobras completes Libra appraisal well drilling

Petrobras has completed the drilling of the first appraisal well in the Libra Consortium area, the 3-BRSA-1255 (3-RJS-731), informally known as NW1.

Located in the northwest portion of the Libra block, in the pre-salt layer of the Santos Basin, the well is approximately 4 km southeast of the discovery well, the 2-ANP-2A-RJS.

The well has reached a final depth of 5734 m and is located 185 km off the coast of Rio de Janeiro, at a water depth of 1963 m. The drilling results have confirmed an oil column of approximately 290 m and a reservoir that shows good porosity and permeability.

Samples collected from the well have confirmed that the oil of 27 degrees API is the same as the one found in the well 2-ANP-2A-RJS. A formation test is expected in the oil-bearing zone to verify its characteristics and the reservoir productivity.

The Libra Consortium (Petrobras, Total, CNPC, CNOOC Limited and the Pré-Sal Petróleo) will proceed with the activities set forth in the Exploratory Plan approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency.
