The Libra Consortium has completed the drilling of the extension well 3-BRSA-1267-RJS/3-BRSA-1267A-RJS (3-RJS-735/735A). The drilling results have confirmed the presence of a hydrocarbon-bearing column of approximately 200 meters of good reservoir characteristics. Informally known as C1, the well is located in the crest of the central area of the Libra block, in Santos Basin, about 220 km off the coast of Rio de Janeiro city.

The final depth reached was -5,780 meters, with 2,160 meters of water depth. This is the second successful well drilled by the Libra Consortium and it is located
18 km from the first well, 3-RJS-731.

A full suite of logs was acquired. Fluid samples containing hydrocarbons and CO2 were taken and are undergoing detailed analysis in the laboratory. The Consortium will continue with the exploratory plan and will drill new wells to evaluate the Libra area which encompasses 1,550 sq. km.

The Libra Consortium is composed of Petrobras (operator, with 40%), Total (20%), Shell (20%), CNPC (10%) and CNOOC (10%), along with the state company Pré-Sal Petróleo S.A. (PPSA) as contract manager.
