Petrobras Drills New well in Libra – World Oil
Petrobras has concluded the drilling of well 3-BRSA-1305A-RJS (3-RJS-739A), in 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 m 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).
In well 3-RJS-741, the oil-bearing zone was identified by wireline logging and fluid samples, which will be characterized by laboratory analysis. The well is being drilled at a depth of 5,527 m. Well 3-RJS-742 was spud on Feb. 6.
The Libra consortium is composed of Petrobras (operator, with a 40% working interest), Shell (20%), Total (20%), CNPC (10%) and CNOOC (10%), and the contract manager is Pré-Sal Petróleo S.A. (PPSA).
