A Petrobras returned to producing above 1 million barrels per day in the Tupi field, in the Santos Basin pre-salt, as a result of investments to recover the asset’s productivity, said the oil company’s president, Magda Chambriard, this Tuesday (13).
The level was reached last Friday (9), after Petrobras interconnected eleven wells in Tupi throughout 2025, totaling 150 wells drilled in the asset.
“This is the result of an effort by the company and the company’s team that took Tupi — which was once the largest in Brazil, but was in decline and was overtaken by Búzios — and brought it back to that level,” Chambriard told Reuters.
“It’s the rescue of a symbol for Brazil, and Petrobras is always looking for more,” he added.
The level of 1 million barrels per day in the field had been reached for the first time in 2019.
Petrobras is studying the construction of other wells in Tupi, in addition to evaluating the possibility of a new platform, starting in 2031, and extending the useful life of some of the nine existing ones, with the objective of continuously generating value from the asset.
The implementation of such activities, however, is subject to the necessary approvals from Petrobras’ partners in the consortium responsible for the field and the sector’s regulatory agency ANP, such as the analysis of the license extension request.
The first highly productive pre-salt field, Tupi is operated by Petrobras, with partners Shell and Galp.
In a statement, Petrobras stated that Tupi’s return to production of 1 million barrels per day reinforces that the pre-salt, over 16 years, has become one of the most competitive oil frontiers in the global industry.
Of the 57 production platforms currently operated by Petrobras, 28 are exclusively in the pre-salt, which reached accumulated production of 7 billion barrels of oil in January 2025, led by the three largest fields in operation in this layer: Tupi, Búzios — the largest in the world in ultra-deep waters —, and Mero.
