Yesterday, Petrobras, the national oil giant of Brazil, announced a groundbreaking oil discovery in the deep waters of the Potiguar Basin.
This find, located at the Anhangá exploratory well, is in the middle of Brazil’s equatorial margin, a zone stretching from Amapá to Rio Grande do Norte.
This area is now seen as Brazil’s next big area for oil and gas exploration due to its rich potential.
However, the project has sparked controversy due to environmental concerns, especially because it’s close to the Amazon River.
The equatorial margin is home to multiple basins, including not just Potiguar but also Foz do Amazonas, Pará-Maranhão, Barreirinhos, and Ceará.
The newly discovered oil reserve lies 2,196 meters below the surface.
Located at the Ceará and Rio Grande do Norte border, the Anhangá well is about 190 km from Fortaleza and 250 km from Natal, far from major cities.
This discovery follows another significant find in the Potiguar Basin earlier in 2024, at the Pitu Oeste well.
With Petrobras owning complete stakes in these projects, the company has stated that further analysis is needed to understand the full potential of these discoveries.
Petrobras has assured that the exploration process has been conducted without any harm to workers or the environment.
Moreover, the company is broadening its exploration efforts beyond the Brazilian equatorial margin.
It has acquired exploration rights in the Pelotas Basin in southern Brazil and has also invested in three blocks off the coast of São Tomé and Príncipe in West Africa.
With an investment plan of $7.5 billion set for exploration up to 2028, Petrobras is focusing $3.1 billion on the equatorial margin area, from Amapá to Rio Grande do Norte.
The company plans to drill 50 new exploratory wells, including 16 in the equatorial margin, to boost Brazil’s oil and gas output responsibly.
