Petrobras has begun oil production from the P-78 floating production, storage and offloading (FPSO) vessel in the Búzios field, in the pre-salt layer of the Santos Basin.
Búzios 6 (P-78) has the capacity to produce 180,000 barrels of oil and 7.2 million cubic metres of gas per day. The FPSO will increase the field's installed production capacity to approximately 1.15 million barrels of oil per day. The project will also allow for the export of gas to the mainland via interconnection with the ROTA 3 gas pipeline , expanding Brazil's gas supply by up to 3mn cubic metres per day .
"With the first oil from the P-78 platform, we are starting the year already advancing towards 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 also expanding the supply of natural gas to the Brazilian market, another goal expressed in our Business Plan," said Magda Chambriard, president of Petrobras.
The P-78 is an FPSO (Floating Production, Storage and Offloading) unit and inaugurates a new family of proprietary unit projects, bringing even greater safety and reliability to operations. The platform is equipped with technologies for reducing emissions and increasing operational efficiency, notably the exhaust gas recovery system, the adoption of variable speed drives in pumps and compressors, and energy integrations between hot and cold streams in oil and gas processing.
The project comprises 13 wells, 6 producers and 7 injectors, equipped with intelligent completion systems that enhance production management. The unit will be interconnected with rigid pipelines for production, injection and gas export, and flexible pipelines for service lines, using innovative technologies for attaching the pipelines to the FPSO. These pipelines will allow for the high-capacity production planned for the field's wells.
The platform is the seventh in operation in the Búzios field, the largest in the country in terms of reserves. Located 180 km off the coast of the state of Rio de Janeiro, in ultra-deep waters of the Santos Basin, at a depth of more than 2,000 meters, it surpassed 1mn bpd production in October 2025.
