PETROBRAS DISCOVERS OIL IN ULTRA-DEEP WATERS OF THE POTIGUAR BASIN

Petrobras has discovered an oil accumulation in the ultra-deep waters of the Potiguar Basin in the Anhangá exploratory well of the POT-M-762_R15 Concession. The 1-BRSA-1390-RNS (Anhangá) well is located near the border between the states of Ceará and Rio Grande do Norte, about 190 km from Fortaleza and 250 km from Natal, at a water depth of 2,196 meters, on the Brazilian Equatorial Margin.

This is the second discovery in the Potiguar Basin in 2024, preceded by proof of the presence of hydrocarbons in the Pitu Oeste Well, located in the BM-POT-17 Concession, around 24 km from Anhangá. These discoveries still require further assessment. Petrobras is the operator of both concessions and holds a 100% stake.

The exploratory activities in the Equatorial Margin represent another step in Petrobras' commitment to replenishing reserves and developing new exploratory frontiers to ensure that global energy demand is met during the energy transition.

In addition to its activities in the Brazilian Equatorial Margin, in 2023, the company acquired 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.




About the discovery in Anhangá
The discovery of Albian-age turbidite reservoirs carrying oil is unprecedented in the Potiguar Basin and was made through electrical profiles and oil samples, which will later be characterized through laboratory analysis. Petrobras will continue its exploratory activities in the POT-M-762_R15 Concession, aiming to assess the reservoirs' quality, the oil's characteristics, and the technical-commercial viability of the accumulation.

To evaluate the discoveries, Petrobras is applying geological and geophysical technological solutions, combined with the expertise and excellence of the company's technical staff and its world leadership in deep and ultra-deepwater operations.

This second exploratory well was also conducted safely and within the strictest deepwater operation protocols. This reaffirms that Petrobras is prepared to carry out activities in the Equatorial Margin with total responsibility.

The exploratory success in Guyana and Suriname corroborates the importance of Petrobras continuing its campaign in the Brazilian Equatorial Margin Basins, as set out in its Strategic Plan 2024-2028.
