South America consolidates itself as the new global oil frontier.

247 - South America is experiencing a moment of prominence in the global energy landscape, driven by discoveries and billion-dollar investments that promise to transform the region into the new global oil frontier. According to reporter According to The Economist magazine, Brazil, Guyana, and Argentina are highlighted, with projects and prospects placing the continent at the center of attention for the world's largest oil companies.

On August 5th, the British company BP announced not only a quarterly profit of US$2,4 billion—30% above analysts' expectations—but also the company's largest oil discovery in 25 years. The field, named Boomerang, is located about 400 km off the coast of Rio de Janeiro and is already seen as a milestone for the Brazilian sector. The discovery should attract even more interest to the oil block auction scheduled for October, which already has giants like Chevron, Shell, and TotalEnergies in the running.

Brazil: a rising power in the South Atlantic

Consulting firm Rystad Energy projects that crude oil production in Brazil will increase by 10% in 2025, exceeding 3,7 million barrels per day (b/d). In addition to Petrobras, which continues to expand its exploration capacity, Equinor—the Norwegian state-owned company—already operates in fields near the Bumerangue field. Analysts point out that the discovery reinforces the attractiveness of strategic areas such as... Equatorial Margin, considered one of the last exploratory frontiers on the planet, with the potential to place Brazil on a new level in the geopolitics of oil.

The Equatorial Margin is an extensive maritime strip stretching from Amapá to Rio Grande do Norte, with geological characteristics similar to the basins of Guyana and Suriname, which have already become major producers. Studies indicate that the region may hold significant reserves of oil and natural gas, capable of generating billions in investments and royalties, as well as boosting the creation of direct and indirect jobs.

Pressure for fast-track licensing

In this context where international oil companies are making significant discoveries, experts warn of the importance of accelerating the environmental licensing process that will allow Petrobras to begin exploration of the Equatorial Margin. Delays in this process could compromise Brazilian competitiveness against neighbors who are already reaping significant results, such as Guyana. The state-owned company argues that it has the technology and robust environmental protocols to carry out drilling safely and with low impact.

Guyana: small in population, giant in reserves.

With fewer than 1 million inhabitants, Guyana is consolidating itself as one of the main growth hubs for the industry. Rystad estimates that national production will increase by 12% this year, reaching 690 b/d and potentially reaching 1,2 million b/d by 2030. The gigantic Stabroek block, located about 200 km off the coast of the capital Georgetown, is explored by ExxonMobil and partners. The dispute over control of operations involved Chevron and was recently resolved through international arbitration.

Argentina: recovery and bet on shale.

Argentina, historically constrained by interventionist policies, is experiencing a resurgence under President Javier Milei. The engine of this growth is Vaca Muerta, a shale formation in the west of the country, whose production increased by 26% in the first quarter of 2025. A large pipeline, planned for 2027, could transport approximately 700 barrels per day to the Atlantic coast, expanding exports.

With North American shale fields showing signs of depletion, the center of gravity of the oil industry may be shifting southward. The combination of new discoveries, regulatory stability, and adequate infrastructure could make South America the fastest-growing region for oil and gas in the coming decades.
