The new permanent sharing offer brings together 23 blocks in the pre-salt, detailing areas in the Campos and Santos basins and defining the next steps for the auction
A relevant update in the Brazilian energy sector was confirmed by the National Agency of Petroleum, Natural Gas and Biofuels on April 6. The notice for the Permanent Production Sharing Offer has been revised to include 23 exploratory blocks in the pre-salt, expanding the initially planned scope.
The bidding process previously included eight areas. The ANP board decided to incorporate an additional 15 blocks on March 27, significantly expanding the offer. The Ministry of Mines and Energy validated the update before the official publication, consolidating the new set of areas available to the market.
Distribution of the areas reinforces the potential of the pre-salt
The offered areas are concentrated in the Pre-Salt Polygon, located along the coast of the Southeast region. This geographical cut includes two of the country’s main oil provinces, which increases the strategic interest of companies in the sector.

Brazil has oil, but not gasoline: the country produces more than 4 million barrels per day, consumes less than half, but remains dependent on imports, says former CEO of Petrobras.
In the Santos Basin, the blocks listed are Ágata, Amazonita, Aragonita, Calcedônia, Cerussita, Cruzeiro do Sul, Granada, Jade, Malaquita, Opala, Quartzo, Rodocrosita, Rubi, Safira Leste, and Safira Oeste. In the Campos Basin, Azurita, Calcita, Hematita, Larimar, Magnetita, Ônix, Siderita, and Turmalina are available.
All blocks received favorable environmental assessments, as reported by the ANP. The analysis involved the participation of the Ministry of Mines and Energy and the Ministry of the Environment and Climate Change, ensuring the environmental viability of the offered areas.
Permanent offer increases flexibility for companies
The Permanent Offer has established itself as the main bidding model for oil exploration and production in Brazil. This system allows exploratory blocks to be offered continuously, unlike traditional rounds.
Companies can analyze technical data of the areas over time and subsequently submit proposals when they deem it more appropriate. This model eliminates the need for rigid deadlines and increases flexibility for market players.
The ANP emphasizes that this dynamic strengthens competitiveness and increases the attractiveness of the sector. With the publication of the notice, the blocks begin to receive expressions of interest accompanied by the required guarantees, initiating the practical stage of the process.
Rules of the sharing regime define the criteria for the auction
The sharing regime is applied to the pre-salt areas, where the largest oil reserves in the country are concentrated. In this model, the winning criterion is not the highest signing bonus, which differentiates this system from the concession regime.
The winning company or consortium will be the one that offers the largest share of production surplus to the Union. This surplus corresponds to the profit after the payment of operational costs, being shared with the State.
Additionally, the Union also receives taxes, royalties, and special participation, especially in high-production fields. The government’s interests are represented by Pré-Sal Petróleo S.A., responsible for marketing the oil intended for the Union.
In the concession regime, used in other exploratory areas, the winner is defined by the highest amount paid in signing bonuses, which characterizes a distinct logic of competition.
Recent history shows strong market interest
The ANP conducted three permanent sharing offers in the years 2022, 2023, and 2025. In the most recent auction, five of the seven offered blocks were sold, with a premium of 251.63%, highlighting the interest of companies.
The country also recorded five cycles of permanent offers in the concession regime, held in 2019, 2020, 2022, 2023, and 2025. These results demonstrate the consolidation of the model in the Brazilian regulatory environment.
With the new notice published, companies can formalize expressions of interest in the available blocks. The ANP may set the auction date as soon as there is a formal expression from one or more companies.
The advancement of this new offer reinforces the strategic role of the pre-salt in Brazil and expands opportunities in the oil and gas sector.
