Petrobras, ExxonMobil, and Chevron have won exploration rights in Brazil’s Equatorial Margin, a frontier offshore oil region with high expectations despite years of regulatory delays.
Of the 47 blocks offered in the Foz do Amazonas basin, 19 were sold, making it the most contested area in Brazil’s latest oil auction.
Petrobras and Exxon jointly secured 10 blocks, while Chevron, partnering with China’s CNPC, won nine, outbidding Petrobras in some cases.
This marks a strong vote of confidence in the basin’s potential, as well as in Brazil’s ability to eventually overcome environmental resistance.
Petrobras is still waiting on drilling approval from environmental regulator Ibama for its first well in Foz do Amazonas, located 335 miles from the Amazon River’s mouth. The region is seen as potentially rivalling Brazil’s prolific pre-salt fields.
Analysts note that Exxon could leverage its operational expertise from neighbouring Guyana, and its partnership with Petrobras helps offset regulatory risk. Chevron’s aggressive bidding, even without a Brazilian partner, underscores growing interest in replicating Guyana-Suriname offshore success.
The auction’s timing—during heightened Middle East tensions—also highlights Brazil’s attractiveness as a geopolitically safer oil supply source.
Shell and Karoon were active in the Santos basin, though only 11 of 54 blocks there were sold. Shell passed on the Equatorial Margin due to “multiple risks,” despite having exploration ties with Petrobras in nearby Pelotas.
Environmental opposition was strong, especially ahead of Brazil’s COP30 climate summit. Critics raised concerns over proximity to indigenous territories and biodiversity hotspots like Fernando de Noronha.
Still, the auction was deemed a success by the government, bringing in over 989 million reais ($181 million) in signing bonuses and projected to attract 1.5 billion reais in exploration investments.
