These companies will compete to purchase 37.5 million barrels of oil divided into three lots from the Mero field and one lot from the Búzios field, both located in the pre-salt layer of the Santos Basin.
The Auction
The Mero field, considered the third largest oil field in Brazil by volume, will be one of the main focal points, along with the Búzios field.
According to Agência Brasil, the minimum price limit for the Mero lots will be equivalent to the price of Brent oil minus US$ 4.40, while for the Búzios lot, the price will be Brent minus US$ 4.25.
The total revenue from the sale could reach the impressive mark of R$ 15 billion, an amount that should be allocated to the Social Fund.
Rules of the Competition
The auction will be divided into two phases. If the values of the initial bids are very close, there will be a second phase in a verbal format, where companies can offer values below the stipulated minimum price limit.
At the opening of the international market this Monday (29), the price of Brent oil was quoted around US$ 80, a value that will serve as a reference for the auction.
Transformation of Oil
One barrel of oil, which contains 159 liters, can be refined to produce approximately 40% diesel oil and 18% gasoline.
In addition, it also generates lubricants, jet fuel, and asphalt. The term “Brent” for crude or heavy oil refers to a Shell base in the Shetland Islands, north of Scotland, where the oil was originally extracted.
Exploration Regimes
In Brazil, there are three main regimes for the exploration and production of oil and natural gas: concession, onerous assignment, and production sharing.
In the concession regime, the oil and gas produced belong entirely to the winner of the concession, with the State collecting revenue through taxes.
In the onerous assignment, Petrobras has the right to extract up to five billion barrels in areas of the pre-salt, according to Law No. 12.276/2010.
In the production-sharing regime, the State participates without investing or taking risks, receiving a percentage of the excess production.
The Brazilian Pre-Salt
The pre-salt polygon, located 300 km off the coast of the Santos Basin, is a region rich in light oil, with reserves at depths of up to 7 thousand meters.
This region is known for its giant and supergiant discoveries, offering unparalleled potential in the global oil scenario.
