Petrobras began oil production on December 31 from the P-78 floating production, storage, and offloading (FPSO) vessel in the Búzios Field, in the pre-salt layer of the Santos Basin. With the capacity to produce 180,000 barrels of oil and 7.2 million cubic meters of gas per day, the FPSO will increase the field’s installed production capacity to approximately 1.15 million barrels of oil per day.

Furthermore, the operation will allow gas to be exported to the mainland via an interconnection with the Rota 3 gas pipeline in Itaboraí, Rio de Janeiro, expanding Brazil’s gas supply by up to 3 million cubic meters per day.

“With the first oil from P-78, we are starting the year by advancing toward our main goal for 2026: increasing Petrobras’ oil and gas production. We project producing 2.5 million barrels of oil per day throughout this year, and a large part of that will come from Búzios, the country’s largest field in terms of reserves and production. In addition, we are expanding the supply of natural gas to the Brazilian market, another goal outlined in our Business Plan,” said Petrobras President Magda Chambriard.

According to Petrobras, the platform is equipped with technologies aimed at emissions reduction and greater operational efficiency, including an exhaust gas recovery system, variable-speed drives for pumps and compressors, and energy integration between hot and cold streams in oil and gas processing.

The P-78 is the seventh platform in operation in the Búzios Field, the largest in Brazil in terms of reserves, which surpassed the mark of 1 million barrels per day in October 2025. Discovered in 2010, the field is located 180 kilometers off the coast of the state of Rio de Janeiro, in the ultra-deep waters of the Santos Basin, at a depth of more than 2,000 meters.
