Petrobras has concluded the drilling of well 3-BRSA-1305A-RJS (3-RJS-739A), located on the Libra block, northwest area, in the pre-salt of the Santos Basin, confirming the discovery of good quality oil in reservoirs with excellent productivity.

The well found an oil column of around 270 meters and high-quality reservoirs in communication with previous wells in this area. Two Drill Stem Tests (DSTs), performed on two different intervals, have confirmed the excellent productivity of these reservoirs and good oil quality (28º API), similar to the wells 2-ANP-2A-RJS and 3-RJS-731.

Currently, two other wells are being drilled in the Libra block northwest area: 3-BRSA-1322-RJS (3-RJS-741) and 3-BRSA-1339-RJS (3-RJS-742). The oil-bearing zone of well 3-RJS-741 was identified by wireline logging (set of tools to characterize the reservoir drilled in the well) and fluid samples, which will be characterized by laboratory analysis. The well is being drilled at a depth of 5,527 meters. The well 3-RJS-742 started to be drilled on February 6th.

These three wells are part of the Discovery Evaluation Plan activities of well 2-ANP-2A-RJS, submitted to the National Oil, Natural Gas and Biofuels Agency (ANP), on September 15th 2015, pending on approval.

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