Petrobras is currently drilling two other wells in the northwest portion of the Libra block: 3-BRSA-1322-RJS, also known as 3-RJS-741; and 3-BRSA-1339-RJS, also known as 3-RJS-742.
At 3-BRSA-1322-RJS, the oil carrier range was found through cable profiles—a record of hydrocarbon formations traversed by the well—and fluid samples, which will be characterized by laboratory analyses. The well is at a depth of 5,527 m. The drilling of 3-BRSA-1339-RJS, meanwhile, began on Feb. 6.
The three wells are part of the discovery assessment plan for well 2-ANP-2A-RJS submitted to Brazil’s National Petroleum Agency on Sept. 15, 2015, currently in the approval process.
The Libra consortium comprises operator Petrobras with 40% interest, Royal Dutch Shell PLC 20%, Total SA 20%, and China National Petroleum Corp. and CNOOC Ltd., each with 10%. Contract management is conducted by Pre-Sal Petroleo SA.
