The firms intersected an oil column of around 270 meters and high-quality reservoirs in communication with previous wells in the pre-salt of the Santos Basin.
Upon completion of two drill stem tests on two different intervals, the partners confirmed the good productivity of the reservoirs and good oil quality (28º American Petroleum Institute), similar to the wells 2-ANP-2A-RJS and 3-RJS-731.
At present, Petrobras is drilling two other wells including the 3-BRSA-1322-RJS (3-RJS-741) and 3-BRSA-1339-RJS (3-RJS-742), in the Libra block northwest area.
The oil-bearing zone in the well 3-RJS-741 was identified by wireline logging and fluid samples, which will be characterized by laboratory analysis. The well is planned to be drilled to a depth of 5,527m.
The three wells are being drilled as part of the Discovery Evaluation Plan activities of the well 2-ANP-2A-RJS.
Petrobras operators the Libra prospects with 40% interest while Shell and Total each own 20%. The remaining 20% stake is equally owned by CNPC and China National Petroleum (CNOOC).
