Petrobras Ends Drilling, Testing of First Appraisal Well in Libra Block

Petroleo Brasileiro S.A. (Petrobras) announced Tuesday 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 2.5 miles (4 kilometers) southeast of the discovery well 2-ANP-2A-RJS, and 115 miles (185 kilometers) off the Rio de Janeiro coast.

Drilling results have confirmed the presence of an oil column of around 951 feet (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 (27degree API) of these reservoirs.

The Libra Consortium is comprised of Petrobras as the operator (40 percent), Shell (20 percent), French-owned Total (20 percent), Chinese-owned CNPC (10 percent) and CNOOC (10 percent), and state-owned Pre-Sal Petroleo S.A. (PPSA).
