Petrobras discovered oil in the northwestern part of Sépia oil field in Santos basin in water depths of about 2,000 m off the coast of Rio de Janeiro, Brazil.

Well 4-BRSA-1386D-RJS (the Pedunculo well) spudded late July. The oil-bearing interval was verified by electrical logs and fluid samples, which will be further characterized by laboratory analyses, Petrobras said in a release Oct. 31. The net oil column is one of the thickest ever recorded in Brazil, the company said.

Partners will continue operations to characterize the conditions of the discovered reservoirs and verify the extent of the discovery by conducting well tests.

This discovery lies within the Sépia co-participated area, which covers the Sépia Transfer of Rights (ToR) contract (Petrobras, 100%) and the Sepia ToR Surplus production sharing contract awarded in December 2021 to Petrobras (30%), TotalEnergies (28%), QatarEnergy (21%) and Petronas (21%), with Pre-Sal Petróleo SA as manager.

The Sépia co-participated area is operated by Petrobras, with a stake of 51.9%. TotalEnergies holds 19.2% net interest, alongside QatarEnergy (14.4%) and Petronas (14.4%). The Sépia shared reservoir is currently producing 170,000 barrels of oil per day.

The Sepia shared reservoir is currently producing about 170,000 b/d of oil.
