Petrobras has announced that the Libra Consortium has drilled and tested the first appraisal well in the Libra area, 3-BRSA-1255-RJS (3-RJS-731), known as NW1. Located in the Northwest portion of the Libra block, which sits in the Santos Basin pre-salt, the well is approximately 4 km southeast of the discovery well 2-ANP-2A-RJS, and 185 km off the Rio de Janeiro coast.
Oil column confirmed
Drilling results have confirmed the presence of an oil column of around 290 m and high quality reservoirs. The two production tests – carried out in two different zones - have confirmed the excellent productivity and quality of oil (27º API*) of these reservoirs.
The Libra Consortium is comprised of Petrobras as the operator (40%), Shell (20%), French-owned Total (20%), Chinese-owned CNPC (10%) and CNOOC (10%), and state-owned Pré-Sal Petróleo S.A. (PPSA).
