Petrobras announces the new data obtained with the further drilling of well 4-SPS-86B (4-BRSA-971-SPS), which is testing the Carcara Prospect, in Block BM-S-8 in the ultra-deep waters of the Santos Basin pre-salt. This discovery was previously announced on March 20, 2012.
Located 232 km off the coast of the state of Sao Paulo and at a water depth of 2,027 meters, the well is being drilled within the oil zone at a depth of 6,213 meters, with the aim of determining the total thickness of the oil reservoirs as well as the presence of deeper zones of interest. New oil samples were collected at depths of up to 6,131 meters, which have proven a good oil quality of approx. 31degree API. With the well, it has also been proven that the carbonate reservoirs show outstanding porosity and permeability. The drilling, still in progress, has already confirmed an oil column of over 400 meters, showing reservoirs that are mostly continuous and connected.
The consortium will continue to perform the activities and investments needed to evaluate the area, in accordance with the Evaluation Plan approved by ANP - Agência Nacional do Petroleo, Gas Natural e Biocombustiveis (Brazilian National Petroleum Agency). The consortium is operated by Petrobras (66%) in partnership with Petrogal Brasil (14%), Barra Energia do Brasil Petroleo e Gas Ltda. (10%) and Queiroz Galvao Exploraçao e Produçao S.A. (10%).
