Petrobras announced the new facts obtained with the continuance of the drilling of well 4-SPS-86B (4-BRSA-971-SPS), which is testing the Carcara prospect, on Block BM-S-8 in the ultra-deep waters of the pre-salt in the Santos Basin. The discovery has been previously announced on March 20, 2012.
Located 144 miles (232 kilometers) off the coast of São Paulo State, in water depths of 6,650 feet (2,027 meters), the in progress drilling is occurring inside the oil zone, 20,384 feet (6,213 meters) deep, with the purpose of determining the total thickness of the oil reservoirs, as well as the presence of deeper pay zones.
It has been collected new oil samples up to a depth of 20,115 feet (6,131 meters), which have proven a good 31 degree API oil quality. The well has also proven that the carbonate reservoirs carry outstanding porosity and permeability characteristics.
The in progress drilling has already confirmed an over 1,312-foot (400-meter) column of oil, featuring mostly continuous and connected reservoirs.
The consortium will continue to perform the necessary activities and investments to evaluate the area, according to the Evaluation Plan approved by the ANP - Agência Nacional do Petróleo, Gás Natural e Combustível (Brazilian National Oil, Natural Gas and Biofuels Agency).
The consortium is operated by Petrobras (66%) in partnership with Petrogal Brasil (14%), Barra Energia do Brasil Petróleo e Gás Ltda. (10%) and Queiroz Galvão Exploração e Produção S.A. (10%).
