Petrobras has successfully verified the presence of oil in deepwater of Ceara Basin during drilling operations of the 1-BRSA-1080-CES (1-CES-158) well. The well commonly known as Pecém is located 76 km away from the county of Paracuru, on the Ceara state coast, at a water depth of 2,129m. The well's current depth is 4,410m and the drilling shall continue down to 5,500m.
The discovery occurred in siliciclastic reservoirs of Paracuru Formation, verified due to the evidence of hydrocarbon, during drilling operations, logging analysis and results of wireline tests. The samples of fluid collected from the well indicated the presence of liquid hydrocarbonate to be defined by means of laboratory analysis.
Petrobras operates the BM-CE-2 concession, with 60% interest, in consortium with BP Energy do Brasil Ltda, which holds 40%. The Consortium will continue the operations to complete the drilling project of the well until the estimated depth, check the extension of the new discovery and define the permeability and porosity of the reservoirs.
BP announced in March 2012 that the Brazilian National Petroleum Agency (ANP) had approved its farm-in to four deepwater exploration and production concessions operated by Petrobras in the Brazilian equatorial margin. BP Energy do Brasil Ltda. took a 40 per cent interest in each of the blocks, located in the Barreirinhas and Ceara basins, from Petrobras. The move gave BP access to four new concession blocks in Brazil: BM-BAR-3 and BM-BAR-5 in the Barreirinhas basin, and BM-CE-1 and BM-CE-2 (where the above oil discovery has been made) in the Ceara basin. Together the blocks cover a total area of 2,113 sq kms.
