Petrobras bolsters Libra discovery with oil-bearing Santos Basin extension well

27th October 2014

The Petrobras-led Libra consortium has said that the first extension well in the Libra area, known as 3-BRSA-1255-RJS (3-RJS-731), has proven the discovery of high-quality oil in the northwest portion of the structure

The well, informally known as NW1, is located in the pre-salt of Santos Basin, at about 170-kilometres off the coast of the state of Rio de Janeiro and approximately 4-kilometres southeast of the discovery well, 2-ANP-2A-RJS.

The oil-bearing interval was observed by means of fluid profiles and samples, which will subsequently be characterised through laboratory analysis. The well is still being drilled, currently at a depth of 5,326 metres, and drilling will continue until 5,850 metres.

The consortium will continue with the operations to complete the well drilling plan until the planned depth is hit, to verify the extension of the new discovery, and to characterize the conditions of the reservoirs found.

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), and the contract manager is Pré-Sal Petróleo S.A. (PPSA).

Libra was the first area auctioned by Brazil’s Oil, Natural Gas and Biofuels Agency (ANP) under the production sharing regime.
