Petrobras confirms 200-metre hydrocarbon column at Libra field drill offshore Brazil

25th March 2015

The Petrobras-led Libra consortium has finished drilling extension well 3-BRSA-1267-RJS/3-BRSA-1267A-RJS (3-RJS-735/735A)

Petrobras confirms 200-metre hydrocarbon column at Libra field drill offshore Brazil
The consortium will continue with the exploration plan by drilling new wells in order to evaluate the Libra area, which covers around 1,550 square kilometres.

The drilling results confirmed the presence of a hydrocarbon column approximately 200 metres 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 metres, including a water depth of 2,160 metres. 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 characterised 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 square kilometres.

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