Libra appraisal well hits 410 m of net pay, Petrobras says


RIO DE JANEIRO -- The Libra Consortium has finished drilling and appraising the seventh well in the block. According to Petrobras, the well uncovered the largest net pay ever discovered—410 m—in the Libra Block. This column exceeds the last one discovered (301 m), which was announced in March. 

The new well, which lies in the northwestern section of the block, 180 km off the coast of Rio de Janeiro, confirmed the discovery of good-quality oil (27º API) in highly productive reservoirs.

The well, named 3-BRSA-1339A-RJS (3-RJS-742A) and informally known as NW2, lies 10.3 km to the south of the 2-ANP-2A-RJS discovery well.

So far, seven wells have been drilled in the Libra Block, and the eighth well (3-RJS-743A), which is also in the northwestern part of the block, is currently being drilled.

The Libra Consortium is comprised of Petrobras (operator, 40%), Shell (20%), Total (20%), CNPC (10%) and CNOOC (10%). The production sharing agreement is managed by Pré-Sal Petróleo S.A.
