RIO DE JANEIRO, Brazil – Petrobras and its partners have discovered oil in the northwestern part of the co-participated area of Sépia in the presalt Santos Basin offshore Brazil.

Well 4-BRSA-1386D-RJS was spud on July 31, 250 km south of Rio de Janeiro in a water depth of 2,197 m, and about three months after the signing of the Sépia Transfer of Rights (ToR) Surplus consortium.

Electrical logs and fluid samples confirmed the oil-bearing interval, which will be subjected to further laboratory analyses. According to Petrobras, the net oil column is one of the thickest ever recorded in Brazil.

The consortium plans to continue assessment of the reservoirs and to delineate the extent of the discovery.

The Sépia co-participated area comprises the Sépia Block, which Petrobras acquired under a Transfer of Rights contract in 2010, and the Sépia ToR Surplus Block, acquired in December 2021 under the ANP’s 2nd ToR production sharing auction in late 2021.

In the latter case, the consortium partners are Petrobras (operator), TotalEnergies, QatarEnergy and Petronas Petróleo Brasil, with Pre-Sal Petróleo as manager.
