ANP Approved the Inclusion of 275 Exploratory Blocks in Permanent Offer Auction, with Areas in Basins Such as Campos, Santos, Ceará, Espírito Santo, and Recôncavo. Learn How the Process Will Work.

The National Agency of Petroleum, Natural Gas and Biofuels (ANP) approved, on Thursday (09/18), the inclusion of 275 exploratory blocks and five areas with marginal accumulations in the Permanent Offering of Concession (OPC) notice.

The decision expands opportunities for companies in the sector and reinforces the role of the auction model as the main bidding instrument for oil and gas exploration and production in the country.

Constituted Basins and Regional Expansion

The blocks cover strategic and mature basins. Among them are Campos, Santos, Parnaíba, Ceará, Espírito Santo, Potiguar, Recôncavo, São Francisco, Tacutu, and Tucano Sul. The geographical diversity is seen as an attraction for companies interested in assessing risks and opportunities in different areas of the national territory.

In July, ANP itself highlighted that the permanent offer modality facilitates the entry of new players into the sector, as the blocks remain continuously available, without solely depending on annual rounds.

How the ANP Auction Process Works

The OPC model differs from traditional rounds because it allows companies to choose the ideal time to submit their proposals. This ensures greater flexibility for investors and strengthens competitiveness. 

After approval by the board, the updated notice will go through a public hearing on October 9. In this event, society and the market may suggest changes before the publication of the final version.

Only after this stage will the blocks be effectively released for expression of interest by companies already registered in the OPC. There is still no defined date for the opening of a new offering cycle.

Difference Between OPC and OPP

Currently, the permanent offer is divided into two regimes. The OPC (Permanent Concession Offer) is aimed at areas with lower exploratory risk, generally in mature basins, where companies fully assume the costs and risks of the activity, in addition to paying government participations.

The OPP (Permanent Production Sharing Offer) is applied in strategic areas, especially in the pre-salt layer, where the Union participates directly in production and the revenue obtained. While the OPC focuses on regions such as Recôncavo, Parnaíba, and Potiguar, the OPP stands out in fields with great potential, such as Búzios and Atapu, located in the pre-salt of the Santos Basin.

Market Expectations

Experts assess that the expansion of the number of blocks demonstrates ANP’s intent to keep Brazil attractive for investments, especially at a time of increased global competitiveness. For the sector, the inclusion of diversified areas can stimulate new discoveries and energize regional economies.

Furthermore, the presence of mature basins in the auction indicates that ANP is betting on solutions that leverage existing infrastructure while also opening up space for new exploration frontiers.
