Petrobras expects to begin extracting oil from the ultra-deepwater Margem Equatorial region in approximately seven years [1].
The project represents a strategic shift for Brazil as the company seeks to diversify its production beyond the established pre-salt fields. By expanding into the Foz do Rio Amazonas basin, Petrobras aims to secure a new frontier of hydrocarbon resources to maintain long-term output levels.
The estimate, first shared in May 2026, suggests that production could start around 2033 [2]. This timeline follows the discovery of hydrocarbons in an exploratory well within the region, which prompted the company to evaluate the area's full potential [3].
Magda Chambriard, president of Petrobras, said the drilling license from Ibama marks the beginning of a new front for the company. She said the firm expects to initiate production within approximately seven years [3].
The Margem Equatorial area consists of ultra-deepwaters located off the coast of Amapá. Petrobras officials said the company evaluates that it could be producing oil in these waters by the 2033 target date [1].
This expansion is viewed as a technological leap similar to the one the country experienced 20 years ago during the development of the pre-salt layer. The company is now focusing on the technical challenges of operating in the extreme depths of the Amazon river mouth basin [2].
While the company has identified the potential for production, the timeline remains an estimate. The transition from exploratory drilling to full-scale extraction requires significant infrastructure investment, and continued regulatory approval from environmental agencies [3].
“Petrobras expects to begin extracting oil from the ultra-deepwater Margem Equatorial region in approximately seven years.”
The move into the Margem Equatorial is a critical hedge against the natural decline of Brazil's pre-salt reserves. By establishing a second major production hub in the Foz do Rio Amazonas basin, Petrobras aims to ensure Brazil remains a global oil powerhouse. However, the seven-year window underscores the immense technical and environmental hurdles associated with ultra-deepwater drilling in ecologically sensitive regions.
