Petrobras discovers 200-m hydrocarbon column at Libra C1 extension well

RIO DE JANEIRO -- The Libra consortium has finished drilling extension well C1. The drilling results confirmed the presence of a hydrocarbon column approximately 200 m deep in reservoirs with good permeability and porosity characteristics.

The C1 well is located in the central part of the Libra block, in Santos basin, around 220 km offshore from 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 sq km.

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