Petrobras Auction Involving Strategic Oil and Gas Areas in the Pre-Salt of the Santos Basin Will Be Held in December at B3, With Recent Discoveries Boosting Interest from Major Oil Companies.

The Brazilian oil sector is gaining prominence with the confirmation of the Petrobras auction, scheduled for December 4, at B3, in São Paulo, as reported this Tuesday, 09/17. The bidding involves strategic areas of the Santos Basin, which encompasses the coasts of São Paulo and Rio de Janeiro. In addition to the sale of the Union’s stake in already discovered fields, recent discoveries further enhance the region’s attractiveness.

Auction Details and Union Participation

Pré-Sal Petróleo (PPSA) confirmed that the auction will sell the entire Union’s stake in three shared fields: Mero, Tupi, and Atapu. Currently, these percentages represent 3.500% in Mero, 0.551% in Tupi, and 0.950% in Atapu.

Interested companies will be able to access complete technical data packages, offered in virtual format. It will also be possible to schedule in-person meetings, ensuring transparency and greater security in the process.

In parallel to the auction, Petrobras announced important advancements in the Aram block, also located in the Santos Basin. Two wells have already confirmed the presence of high-quality oil. A third well was recently drilled, while two others are in the exploration phase.

According to the state-owned company, all stages follow the approved Discovery Evaluation Plan (PAD) by the National Agency of Petroleum, Natural Gas and Biofuels (ANP). The project is viewed as strategic for assuring new production flows and expanding Brazilian presence in the international market.

BP Energy and the Biggest Discovery in 25 Years

International interest in the pre-salt is growing with the entry of new companies. The British oil company BP Energy revealed the discovery of a significant reservoir in the Bumerangue block, also in the Santos Basin. Well 1-BP-13-SPS is located 404 km off the coast of Rio de Janeiro and about 300 km from Santos, at a depth of 5,855 meters.

The Executive Vice President of Production and Operations at BP, Gordon Birrell, highlighted that this is the company’s biggest discovery in the last 25 years. According to him, “the company’s excitement about the pre-salt potential is immense, and the expectation is to create a relevant production hub in Brazil.”

These exploratory advancements and the Petrobras auction reinforce the strategic importance of the Santos Basin in the global energy landscape. The coast of São Paulo and Rio de Janeiro is consolidating as an investment hub, attracting both the Brazilian state-owned company and major multinationals.

For specialists, the combination of new discoveries and the sale of the Union’s stakes is expected to generate strong financial movement, as well as boost revenue and development in the region.
