With Promise of Investments and Focus on Energy Security, Government Resumes 17 Blocks from the Potiguar Basin for Strategic Auction in the Brazilian Equatorial Margin
The federal government confirmed that 17 blocks from the Potiguar Basin will be included in the next auction of areas intended for the exploration of oil and natural gas. The bidding will take place on June 17, as part of the 5th Cycle of the Permanent Concession Offering (OPC), coordinated by the National Agency of Petroleum, Natural Gas and Biofuels (ANP).
The initiative aims to attract investors to the Brazilian Equatorial Margin, a region that is still underexplored but considered to have high potential. Of the offered blocks, 16 are located in deep waters and only one in shallow waters.
Minimum Investment and Signing Bonus
According to the Ministry of Mines and Energy, the minimum investment commitments, set forth in the Minimum Exploratory Programs (PEM), must reach R$ 489.17 million.

While Petrobras operates at 7,000 meters in the pre-salt layer, China is extracting oil and gas at 10,910 meters onshore — Shenditake 1 is the world’s first onshore well to exceed 10 km.
Additionally, the government estimates that it will collect R$ 59.8 million in signing bonuses, an amount paid by the winning companies at the time of concession.
Despite the estimated volume, the blocks are in the exploratory phase, with no guarantee of future production. Effective production will depend on subsequent stages, such as seismic data collection and well drilling, which will still be conducted after the auction.
Areas Classified as “New Frontier”
The offered areas are considered to be “New Frontier.” This means they have little or no production recorded to date, in addition to limited infrastructure.
These factors represent high risks for investors, but also offer opportunities for discoveries, especially in light of recent interest in the Equatorial Margin.
The region gained international prominence after significant hydrocarbon finds in Guyana and Suriname. The Potiguar Basin itself has also recorded discoveries that increased the attractiveness of the blocks.
Strategic Objectives and Regional Development
The ANP assesses that the auction represents a chance to expand the geological knowledge of the sedimentary basins in the country. Another objective is the replenishment of the national reserves of oil and gas, deemed essential for Brazil’s energy security.
Moreover, the agency highlights possible social and economic benefits, such as job and income generation in the regions where exploratory activities occur.
Blocks in Dispute and Company Participation
A total of 332 blocks will be auctioned across 16 different sectors. Among the basins included are Parecis, Pelotas, Santos, Potiguar, and Foz do Amazonas. Thirty-one companies are qualified to participate in the process, including Petrobras.
Interested companies must submit their expressions of interest and offer guarantees by May 12.
Change in Block List After Reassessment
In February, the government had announced the removal of 15 blocks from the Potiguar Basin, citing environmental issues. However, after reviewing technical documents, an error in interpreting the information was found. As a result, the original 17 blocks were retained for the round.
Equatorial Margin May Contain 10 Billion Barrels
According to the Energy Research Company (EPE), the potential of the Equatorial Margin may reach 10 billion barrels of oil. The entity warns that without new discoveries and investments, Brazil may revert to depending on imported oil by the end of the 2030s.
