Petrobras has finished drilling the first appraisal well in the Appraisal Plan Area following the Barra discovery in the deep waters of the Sergipe-Alagoas Basin.
Known informally as Barra 1, the 3-SES-165 well is located around 100 km from the municipality of Aracaju, of the coast of the State of Sergipe, at a water depth of 2,433 m and approximately 10 km southeast of the wildcat well, 1-SES-158 (Barra).
The objectives of drilling Barra 1 were to verify the southeastern extension of the gas accumulation discovered by the wildcat well in the sandstones of the upper section of Calumbi Formation, and to investigate the continuity in the same direction of oil-saturated sandy reservoirs in the lower section of Calumbi Formation, found by well 1-SES-158.
Both objectives have been achieved, allowing the Barra accumulation to be delimited, as projected, and confirming the southeastern continuity of oil saturated reservoirs in the lower section. These reservoirs are located between 5460 and 5500 m, where there are light oil saturates with an API of 38 degrees were found.
Petrobras is the operator of the BM-SEAL-11 concession (60%), in partnership with IBV Brasil (40%). The consortium is to continue operations in the area to confirm the extension of the new discovery and characterize the conditions of the reservoirs found.
