The New Bidding Round Promises to Move Billions, with the Inclusion of New Basins and Large Companies Competing for Strategic Blocks. The Auction’s Impact is Expected to Shape the Country’s Energy Future.
New Oil and Gas Sectors Are Opened for Bidding by ANP in 2025
The National Agency of Oil, Natural Gas and Biofuels (ANP) announced the sectors that will be offered in the 5th Cycle of the Permanent Concession Offering (OPC), with the auction scheduled for June 17, 2025.
The round will cover 16 sectors distributed among five Brazilian sedimentary basins — four offshore and one onshore — and represents a new opportunity for advancing oil and gas exploration in the country.
The big news is the inclusion of the Foz do Amazonas Basin, which appears for the first time in the permanent offering model, even though it is still under environmental assessment by the Brazilian Institute of Environment and Renewable Natural Resources (Ibama).

Strategic Basins Gain Protagonism
According to official information from ANP, the new bidding cycle will include four sectors in the Foz do Amazonas Basin, five sectors in the Santos Basin, four sectors in the Pelotas Basin, one sector in the Potiguar Basin, and two sectors in the Parecis Basin.
The Parecis Basin is the only onshore basin included in this round, while all others are offshore, highlighting the industry’s preference for offshore reservoirs.
Basins like Santos and Pelotas have already seen blocks awarded in previous cycles, which demonstrates a continuous interest from the energy sector in these regions.
These areas are seen as promising by experts due to their still underexplored potential and proximity to areas where significant discoveries have already been made.
Foz do Amazonas: Energy Potential and Environmental Challenge
The inclusion of the Foz do Amazonas Basin in the OPC cycle marks a strategic move by ANP.
The goal is to attract investments to a region rich in energy potential, but which raises environmental concerns due to its proximity to the mouth of one of the largest rivers in the world and sensitive ecosystems of the Amazon.
According to information from Ibama updated until March 2025, the authorization for drilling in the region has not yet been granted, and environmental impact studies are still under review.
Environmental organizations and local communities have pressed for more transparency and rigor in licensing, while companies in the sector argue that it is possible to reconcile exploration and preservation.
Global and National Companies in the Competition
The list of companies qualified to participate in the round has already been published, including international giants such as BP Energy, Chevron, Equinor, ExxonMobil, Shell, and TotalEnergies.
Also included in the list are Petrobras and other smaller national companies, reinforcing the diversity of profiles interested in the offered blocks.
In total, 31 companies have been qualified so far, according to information from the Federal Official Gazette and the Special Bidding Committee of ANP.
These companies have until May 12 to submit declarations of interest and financial guarantees for the blocks they wish to compete for.
Permanent Concession Offering Model
The Permanent Concession Offering system is one of the major regulatory innovations in the oil and gas sector in Brazil.
Unlike traditional auctions, this model allows companies to express interest in exploration blocks at any time.
The auctions are conducted on demand, whenever there is proven interest from one or more companies in specific areas previously approved by the government.
This format provides more flexibility to the market, reduces regulatory costs, and accelerates the concession processes, benefiting both the public sector and investors.
According to ANP, the model aims to stimulate the sector and expand the utilization of the national energy potential, especially in less attractive areas under traditional models.
Economic Potential and Projections for 2025
The new bidding round occurs at a strategic moment for Brazil, which has sought to consolidate its position as one of the major global players in oil production.
According to data from ANP itself and the Energy Research Company (EPE), national oil production may surpass 4.3 million barrels per day by the end of 2025, driven precisely by new projects in exploratory areas.
Revenue from royalties and special participations for producing states and municipalities is also expected to grow significantly in the coming years, contributing to regional development.
The entry of new exploratory blocks into the market strengthens the country’s role as an energy powerhouse and attracts international attention, in a context of gradual energy transition and diversification of the matrix.
Environmental and Social Challenges Under Debate
Despite the enthusiasm from the economic sector, environmental experts warn of the risks associated with the expansion of exploration in sensitive areas like the Foz do Amazonas.
Scientific studies indicate that the region harbors unique biodiversity, as well as indigenous and riverside communities that depend on local natural resources.
According to environmentalists, the absence of conclusive data on the potential impacts of oil activities in the area requires more caution before final approval.
ANP states that only operations that strictly meet technical and legal criteria will be approved, in accordance with the requirements of Ibama and other environmental entities.
Expectations and Next Steps
With the auction scheduled for June 17, the market eagerly awaits the developments of this round, which could mobilize billions in investments in the coming years.
The results of the 5th Cycle of the OPC could redefine the map of oil exploration in Brazil, opening new energy frontiers and influencing strategic decisions of major companies.
To monitor the advancements, the sector will remain attentive to environmental authorizations, corporate positioning, and government signals regarding the balance between economic exploration and social-environmental responsibility.
The new bidding round from ANP represents an important milestone in Brazil’s energy policy for 2025.
With great investment opportunities, high competitiveness, and complex social-environmental challenges, the 5th Cycle of the Permanent Concession Offering promises to be a turning point for the future of oil and gas exploration in the country.
