Petrobras discovers oil in waters of the Potiguar Basin

Petrobras has discovered an accumulation of oil in ultra-deep waters of the Potiguar Basin, in the Anhangá exploratory well, in the POT-M-762_R15 Concession. Well 1-BRSA-1390-RNS (Anhangá) is located close to the border between the states of Ceará and Rio Grande do Norte, approximately 190 km from Fortaleza and 250 km from Natal, in a water depth of 2196 m, on the Brazilian Equatorial Margin.

This is the second discovery in the Potiguar Basin in 2024 and was preceded by the confirmation of the presence of hydrocarbons in the Pitu Oeste Well, located in the BM-POT-17 Concession, approximately 24 km from Anhangá. Such discoveries still deserve additional evaluations. Petrobras is the operator of both concessions and holds a 100% stake.

Exploratory activities in the Equatorial Margin represent another step in Petrobras' commitment to seeking the replacement of reserves and the development of new exploratory frontiers that ensure global energy demand is met during the energy transition.

“The company has a history of almost 3 thousand wells drilled in deep and ultra-deep water environments, without any type of complication or impact on the environment, which, combined with the technical capacity and experience accumulated over almost 70 years, enables the company to open new borders and handle its operations in the Equatorial Margin with complete security,” says Petrobras president Jean Paul Prates.

In addition to activities on the Brazilian Equatorial Margin, the company acquired, in 2023, new blocks in the Pelotas Basin, in southern Brazil, and stakes in three exploratory blocks in São Tomé and Príncipe, a country on the west coast of Africa.
