ANP Approves Inclusion of 275 Blocks in the Permanent Offer under the Concession Regime (OPC)

On September 18, 2025, the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) approved the inclusion of 275 blocks, and five areas with marginal accumulations, in the tender protocol of the Permanent Offer under the Concession Regime (OPC).

The blocks are located in the Campos, Ceará, Espírito Santo, Parnaíba, Potiguar, Recôncavo, Santos, São Francisco, Tacutu, and Tucano Sul basins.

The draft tender protocol, including the new blocks, will be submitted at a public hearing on October 9, 2025, ensuring participation from the market and public.

After receiving and assessing the contributions to the tender protocol, ANP’s Board of Directors will review the final version of the draft.

Once the tender protocol is published, the included blocks will be available for declaration of interest from companies registered in the OPC.

Registered companies may submit declarations of interest, accompanied by bid guarantees, for one or more sectors of blocks made available in the tender protocol.

The opening date for the new OPC cycle has yet to be defined by the ANP.

The Energy practice of Tauil & Chequer Advogados in association with Mayer Brown is available to provide further clarification on this matter.
