Petrobras discovers ‘biggest oil column in Libra so far’

Petrobras has informed that the Libra Consortium has concluded the drilling and the evaluation of the well 3-BRSA-1322-RJS (3-RJS-741), located in the block northwest area, in the Santos Basin pre-salt, offshore Brazil. 

According to the Brazilian company, the well confirmed the discovery of “good quality oil (28º API) in reservoirs with excellent productivity”.

The company said that the well found the biggest oil column discovered by the Consortium in Libra so far, with 301 meters of thickness.

Data collected confirmed that the reservoir characteristics and the oil quality are similar to those found in the other wells in the same northwest area, which may indicate that the reservoirs are interconnected, the company explained.

The well, informally known as NW5, lies 8 km northeast of the discovery well, 2-ANP-2A-RJS, and 200 km off the Rio de Janeiro state coast and is part of the Discovery Evaluation Plan commitment, approved by the National Oil, Natural Gas and Biofuels Agency (ANP) on February 26, 2016.

To date, six wells have been drilled in Libra (five by the Consortium) and the seventh well (3-RJS-742), also in the northwest area of the Libra structure, is being drilled.

The Libra Consortium is composed of Petrobras (operator, with 40% WI), Shell (20%), Total (20%), CNPC (10%) and CNOOC (10%), and the Production Sharing Contract manager is Pré-Sal Petróleo S.A. (PPSA).
