Petrobras has a new oil find at its 4-BRSA-1386D-RJS (Pedunculo) well in the extreme northwest of the Sépia field in Brazil’s Santos Basin. The well spud in late July in a water depth of 2200 m, and the oil-bearing interval was verified by logs and fluid samples. According to Petrobras, the effective thickness of the oil column is one of the largest ever recorded in Brazil.
The discovery is in the Sepia coparticipation area and comprises the Sepia block acquired by Petrobras (100%), and the Sépia-ECO block, which was acquired in December 2021 in the ANP’s second bidding round of surplus volumes. Petrobras (operator) was awarded Sépia-ECO along with partners TotalEnergies, QatarEnergy, and Petronas Petróleo Brasil Ltda., with Pré-Sal Petróleo SA as manager.
The Sépia shared reservoir is currently producing 170,000 B/D.
Petrobras also successfully completed the test at the pioneer well 1-BRSA-1381-SPS (Curaçao) in the pre-salt of the southwestern part of the Santos Basin. The new discovery is located 240 km from the city of Santos-SP, at a depth of 1905 m, in the Aram Block.
The test evaluated a thick range of pre-salt carbonate reservoirs, in which it was possible to know its productivity through dynamic production data, according to Petrobras. During the test, oil samples were collected that will be characterized by laboratory analyses. The consortium will continue its activities in the Aram Block, aiming to evaluate the dimensions and commerciality of the new accumulation.
The block was acquired in March 2020, in the sixth bidding round of the ANP, under the production-sharing regime, with Pré-Sal Petróleo SA as manager.
Petrobras is the operator of the block (80% interest) in partnership with CNPC 20%.
