20th anniversary of Brazil's pre-salt oil discovery: production, internationalization, and sovereignty debates
Key Points
- The 2006 pre-salt discovery made Brazil the 7th largest oil producer; crude oil became the main export item in 2024.
- Since refinery investment did not keep pace with production, the economy reprimarized and external dependence on refined products increased.
- The 2016 law removed Petrobras's sole operatorship; foreign companies began acquiring pre-salt blocks without Petrobras.
- The major 2026 auction of 23 blocks is proceeding without Petrobras; geopolitical risks put Brazil's energy sovereignty on the agenda.
By the Numbers
In the 20th year since the discovery of Brazil's pre-salt oil reserves, this find is seen to have fundamentally transformed the country's economy and energy profile. From 2006 to 2025, proven reserves and production recorded strong growth, elevating Brazil to the position of the world's seventh-largest oil producer. However, the failure of refining capacity to grow in parallel with production pushed the country into a crude oil exporter role, and in 2024, crude oil became Brazil's largest export item. This structure deepens the reprimarization of the economy, limits industrial development, and increases external dependence on refined products.
The production structure of the pre-salt also rapidly internationalized; of the 16 companies operating in the region, only Petrobras Brésil is Brazilian, showing the weight of foreign capital. Law 13,365, passed in 2016, removed Petrobras's sole operatorship and mandatory minimum 30% participation, paving the way for multinational oil companies to form consortia without Petrobras. In this process, Petrobras sold its stakes in the Lapa and Bacalhau fields, creating the first pre-salt production areas without Petrobras for the first time. The state's coordination capacity over reserves and oil revenue weakened with these changes.
With the 20th anniversary of the pre-salt in 2026, the ANP is putting 23 exploration blocks up for tender in a single auction with the largest historical offer; Petrobras expressed no preference for any block. 13 of the 23 blocks attracted interest from six companies and will be auctioned on October 7, 2026. Amid geopolitical crises (Middle East, Russia-Ukraine) shaking oil markets, Brazil's strategic producer position is becoming even more prominent; however, this auction model opens the door to corporate strategies that may not always align with national interests.

Frequently Asked Questions
- How did the pre-salt discovery transform Brazil's oil sector?
- With the 2006 discovery, Brazil became the world's seventh-largest producer; crude oil became the largest export item in 2024, but the lack of refining capacity locked the economy into commodity exports.
- Why was Petrobras's operatorship removed and what were the results?
- The 2016 law eliminated Petrobras's mandatory operatorship and minimum 30% stake; thus, foreign oil companies were able to operate in pre-salt blocks without Petrobras, and Petrobras exited some fields.
- Why is the 2026 auction considered critical?
- A historic 23 blocks are being tendered in a single round with the largest offer ever; Petrobras is not participating, and amid geopolitical crises, Brazil's strategic oil revenues carry the risk of slipping out of national control.
