Petrobras Libra Consortium 2nd Extension Well

(Petrobras, 24.Mar.2015) – The Libra consortium has finished drilling extension well 3-BRSA-1267-RJS/3-BRSA-1267A-RJS (3-RJS-735/735A). The drilling results confirmed the presence of a hydrocarbon column approximately 200 meters deep in reservoirs with good permeability and porosity characteristics.

Informally known as C1, the well is located in the central part of the Libra block, in Santos Basin, around 220 km offshore from the city of Rio de Janeiro.

The final depth reached was 5,780 m, including a water depth of 2,160 m. This is the second well successfully drilled by the Libra consortium, and is 18 km from the first well, called 3-RJS-731.

The hydrocarbon and CO2 bearing intervals were calculated through electrical profiles and fluid samples, which are being characterized through laboratory analysis.

The consortium will continue with the exploration plan by drilling new wells in order to evaluate the Libra area, which covers around 1,550 km2.

The Libra consortium is composed of Petrobras (Operator, 40% WI), Shell (20% WI), Total (20% WI), CNPC (10% WI) and CNOOC (10% WI), as well as Brazilian state-owned company Pré-Sal Petróleo S.A. (PPSA), which is the contract manager.
