Petrobras finishes first appraisal well in Libra Consortium area

RIO DE JANEIRO -- Petrobras completed the drilling of the first appraisal well -- 3-BRSA-1255 (3-RJS-731) -- in the Libra Consortium area on Nov. 6.

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 discovery well 2-ANP-2A-RJS.
 
The well has reached a final depth of 5,734 m and is located 185 km off the coast of Rio de Janeiro, at a water depth of 1,963 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 27 degree API oil is the same as that found in the discovery well. A formation test is expected in the oil-bearing zone to verify its characteristics and the reservoir productivity.

The Libra Consortium -- which is composed of Petrobras (operator, 40%), Shell (20%), Total (20%), CNPC (10%), CNOOC Limited (10%) and the state company Pré-Sal Petróleo S.A. (PPSA) -- will proceed with the activities set forth in the exploratory plan approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency (ANP).
