With Loading Forecast Between 2025 and 2027, 5th Auction Will Be Broadcast on TV B3 and Includes Volumes from the Fields of Mero, Búzios, Itapu, Sépia, and Bacalhau.
PPSA (Pré-Sal Petróleo S.A.) confirmed on Friday, 16, the publication of the final notice for the 5th Oil Auction of the Union, which will offer 78.5 million barrels of oil extracted from the pre-salt to the market. The sale will take place on June 26 at B3 headquarters in São Paulo, with live broadcasting on TV B3.
This will be the largest auction ever held by PPSA, which is responsible for managing production sharing contracts and marketing oil and natural gas belonging to the Union.
Review of Oil Volume and Spotlight on the Mero Field
Initially, the pre-notice anticipated the offer of 75.5 million barrels, but the volume was adjusted to 78.5 million after updates to the production projections for the Mero field — one of the most productive in the pre-salt. The company states that the oil quality and logistical predictability are attracting the attention of global players.

“The updates were presented during the OTC Houston, and the market showed strong interest, especially due to the quality of the oil and the legal certainty of the marketing model adopted,” stated Samir Awad, director of Administration, Finance, and Marketing at PPSA.
Division into Eight Lots and Restricted Participation
The PPSA auction will be divided into eight lots, highlighting the fields of Mero and Búzios, two of the main producing hubs of the pre-salt. The loads will have scheduled loading between September 2025 and February 2027, ensuring long-term planning for buyers. Here is the division of the lots:
- Four Lots from the Mero Field: three with 14 million barrels each and one with 17.5 million barrels
- One Lot from Búzios: 3.5 million barrels
- One Lot from Itapu: 6.5 million barrels
- One Lot from Sépia: 5 million barrels
- One Lot from Bacalhau: 4 million barrels
Participation is open to Brazilian exploration and production (E&P) or refining companies, as well as foreign companies that are part of economic groups with proven activity in these sectors. The formation of consortia is permitted, with up to three members per proposal. However, foreign companies cannot participate alone.
Final Steps Before the Auction
The pre-notice of the auction was open for public consultation from April 2 to 14, during which 32 responses were received. PPSA reported that all responses are available on the institutional website.
The next step will be the disclosure of the minimum price limit (value reserve), which will occur on June 24, two days before the auction takes place.
Union Oil Gains Space in the International Market
With this auction, PPSA reinforces its role as the marketer of oil volumes that belong to the Union, especially in contracts under the production sharing regime. The growth of production in the Mero, Búzios, and Sépia fields, combined with the reliability of the state-owned company, has attracted international buyers interested in light oil with low carbon content, one of the characteristics of the Brazilian pre-salt.
According to PPSA, the commercial modeling includes guarantees of loading and a defined schedule, which increases the attractiveness of the lots offered.
Growing Interest in Brazilian Oil
In international forums and energy sector events, such as OTC Houston, Brazilian oil has been valued for its high quality and lower carbon intensity. This aligns with the global trend of seeking cleaner fuels without compromising energy security and supply reliability.
Director Samir Awad emphasized that PPSA positions itself today as a stable and predictable supplier, with a transparent model aligned with international market practices.
