Petrobras completes appraisal well in Barra

Posted on 23 August 2012

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 as Barra 1, the 3-SES-165 well is located approximately 100 km from the municipality of Aracaju in the state of Sergipe. The well is located in a water depth of 2,433 meters and approximately 10 km southeast of the 1-SES-158 (Barra) wildcat well.

Barra 1 has achieved its objectives of verifying the southeastern extension of the gas accumulation discovered by the wildcat well in the sandstones of the upper section of Calumbi Formation and of investigating the continuity in the same direction of oil-saturated sandy reservoirs in the lower section of the formation. The new well confirms the southeastern continuity of oil-saturated reservoirs in the lower section. These reservoirs are located between 5,460 meters and 5,500 meters, where API 38° light-oil saturates were found.

Petrobras, operator of the BM-SEAL-11 concession with 60% interest, plans to continue operations in the area with its partner IBV Brasil. The aim is to confirm the extension of the discovery and characterize the conditions of the reservoirs found.
