Driven by pre-salt, oil becomes Brazil's top export Revenues
The discovery of the pre-salt was so significant for Brazil's oil production potential that it led the government to change the regime that authorized companies to explore the submerged resources. 
As a result, the pre-salt areas are governed by the sharing regime. Under this model, surplus oil production—the balance after covering costs—is divided between the company and the Brazilian government. During the auction that authorizes exploration, the company offering the highest share of profits to the federal government is granted the right to explore.
This is distinct from the concession model, which applies to the post-salt period. In this system, the risk of investment and exploration lies with the concessionaire, who becomes the owner of all the oil and gas that may be discovered. In return, the company pays royalties and special participation fees, particularly for large production fields, in addition to a signature bonus upon winning the auction.
New frontiers
Enunciado 4942485-1
With the pre-salt expected to reach its peak in the 2030s, Brazil's oil industry, led by Petrobras, is shifting its focus to new oil frontiers that are believed to hold significant production potential.
One such frontier is the so-called equatorial margin, located off Brazil's northern coast, where exploration is pending a favorable decision from the Brazilian Institute for the Environment and Renewable Natural Resources (Ibama), an agency under the Ministry of the Environment and Climate Change.
Another promising region is the Pelotas Basin, located off Brazil's southern coast. The growing interest in this area is fueled by the discovery of oil wells in Uruguay and off the coasts of Namibia and South Africa. Experts suggest that the geological conditions in these regions are similar, as the continents were once joined tens of millions of years ago. 
According to Petrobras, the company plans to invest $79 billion in exploring new oil and gas frontiers by 2029. Of this amount, 40 percent will be allocated to the South and Southeast regions, 38 percent to the equatorial margin, with the remainder directed towards other countries.

Downstream: Refining and Marketing

While refining is a complex process, the goal is straightforward: to take crude oil, which is virtually unusable in its natural state, and transform it into petroleum products used for a variety of purposes such as heating homes, fueling vehicles and making petrochemical plastics.

Enunciado 4944347-1

Wolcott, Marion Post. Barnsdall oil refinery. Kansas, 1941.

A number of processes are involved in refining depending on the wanted end product. Hydrotreating is used to remove unwanted elements, such as sulphur and nitrogen from hydrocarbons; cracking breaks molecules into smaller fragments to produce gasoline and other lighter hydrocarbons. The gases produced by cracking are used to create other products like synthetic rubber and plastics. When making gasoline, refiners need high octane numbers to prevent engine knocking. Despite knowing the dangers of lead, tetraethyl lead was added to gasoline in the United States in the 1920s in order to increase the octane. Since the U.S. government banned lead in vehicle gasoline in 1996 as part of the U.S. Clean Air Act, refineries use alkylation and reforming to develop high-octane gasoline.
