SALVADOR DE BAHIA, BRAZIL (By Pedro Silva, Energy Analytics Institute, 18.Aug.2025, Words: 430) — The Petrobras-operated Búzios field set a production record and surpassed output of 900,000 barrels per day (b/d) of oil this past weekend.
Búzios — located in the pre-salt layer of the Santos basin, about 180kms off the coast of Rio de Janeiro — was discovered by Petrobras in 2010 and began operations in 2018.
Búzios is operated by Petrobras and has as partners the companies CNOOC and CNPC, in addition to PPSA.

With this new milestone, the field comes closer to the production level of the Tupi field, also in the Santos basin, and may become Brazil’s largest oil producer as early as 2025, Petrobras announced on 18 Aug. 2025 in an official statement.
“The magnitude of the Búzios field, a giant whose extension corresponds to twice the area of Guanabara Bay, allowed us to surpass this exceptional production level with the entry of the fifth well of the FPSO Almirante Tamandaré. Soon, a new unit, P-78, which is already on its way to Brazil, will begin production in this field,” highlighted Petrobras’ director of exploration and production Sylvia Anjos in the statement.

Búzios has the most productive wells in the country, located more than 2,000m deep on the seabed. The thickness of its reservoir is the same height as the Sugarloaf Mountain — and its extension is more than double the size of Guanabara Bay. The field has 6 production units in operation: the platforms P-74, P-75, P-76, P-77 and the FPSOs Almirante Barroso and Almirante Tamandaré.
“In the first half of this year we brought more wells into production than in the whole of last year, among them wells from Búzios with remarkable results that allowed us to reach yet another record, surpassing the mark of 900,000 barrels per day. Each record achieved reinforces the correctness of the strategies adopted by the company,” Petrobras president Magda Chambriard said in the statement.

“Our people have been working hard to increase production while at the same time reducing costs. These are actions aimed at simplifying projects and diversifying suppliers, which have resulted in more oil and gas in more efficient projects. And we are doing all this without forgetting emissions reductions and our commitment to a just energy transition,” Chambriard said.
