Petrobras announces 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.

Drilling results have confirmed the presence of an oil column of around 290 meters 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).

*American Petroleum Institute grade: the higher the API gravity, the higher the market oil price.
