Insights
P-78 startup boosts Búzios output and adds Brazilian gas supply.
Petrobras has brought the P-78 FPSO onstream in the Búzios field with capacity for 180,000 barrels of oil per day and 7.2 million cubic meters of gas per day. The filing states that this lifts installed capacity in Búzios to about 1.15 million barrels per day and follows the field surpassing 1 million barrels per day in
The project is tied into the Rota 3 gas pipeline, which can raise Brazil’s gas supply by up to 3 million cubic meters per day according to the disclosure. The FPSO design incorporates emission-reduction and efficiency technologies such as a flare gas recovery system and variable speed drives, alongside energy integration in processing systems.
The development uses 13 wells with intelligent completion systems and a network of rigid and flexible pipelines designed for high-capacity flow. Future operational data from P-78 and overall Búzios production, as referenced for

Petrobras announces start of production of the P-78 (Búzios 6) in the Búzios field
—
Rio de Janeiro, January 2, 2026 – Petróleo Brasileiro S.A. – Petrobras announces that the FPSO P-78 began production on December 31 in the Búzios field, located in the pre-salt layer of the Santos Basin, with a capacity to produce 180,000 barrels of oil per day, in addition to compressing 7.2 million cubic meters of gas daily.
The unit is part of the Búzios 6 Project, which comprises the seventh system in operation in the field, the largest in Brazil in terms of reserves. With the P-78 coming online, the installed capacity of the field will be expanded to approximately 1.15 million barrels per day. Additionally, the project will enable gas exports to the continent via interconnection with the Rota 3 gas pipeline, increasing Brazil's gas supply by up to 3 million cubic meters per day.
The P-78 inaugurates a new family of proprietary units, designed based on a reference basic project that consolidated hundreds of lessons learned from the first units operating in the pre-salt layer. Furthermore, the FPSO underwent changes in contracting, construction, and assembly strategies, adopting additional technical requirements for quality and efficiency for the shipyards that built it.
The platform is equipped with technologies to reduce emissions and enhance operational efficiency, including the flare gas recovery system, variable speed drives in pumps and compressors, as well as energy integrations between hot and cold streams in oil and gas processing.
The project includes 13 wells (six producers and seven injectors), equipped with intelligent completion systems that maximize production management. The unit will be interconnected with rigid production, injection, and gas export pipelines, as well as flexible lines for service operations, utilizing innovative technologies for pipeline mooring to the FPSO. These pipelines will enable the high-capacity production anticipated for the field's wells.
The P-78 arrived in Brazil in October, coming from Singapore, with commissioning and operational teams on board. This strategy created value by eliminating the need for a stop in sheltered waters in Brazil, while also improving safety, reliability, and operational readiness through the advancement of system commissioning during the transfer to Brazil.
Búzios Field
In October 2025, the Búzios field surpassed the milestone of 1 million barrels per day. This field, discovered in 2010 by well 2-ANP-1-RJS, is 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 over 2,000 meters. Búzios is operated by Petrobras in partnership with CNOOC, CNODC and PPSA, which manages the production sharing contracts.
