Fabiano Rosa
Buzios Field Reservoir Manager
PETROBRAS - Petróleo Brasileiro S.A.
Fabiano joined Petrobras in 2010, specializing in exploration and production with a focus on reservoir engineering. He has worked extensively on exploitation strategies and production development projects for Pre-Salt fields in the Santos Basin, Brazil. From 2011 to 2019, he was part of the Tupi Field team—then the largest producing field in the country—where he coordinated the reservoir disciplines responsible for the asset’s development projects. During this period, six new offshore production systems were implemented, enabling Tupi to become Brazil’s top oil producer and surpass daily production of 1 million barrels of oil.
In 2019, Fabiano moved to the Buzios Field, currently the largest oil field in Brazil, to lead the reservoir technical team in charge of defining and implementing the field’s Development Plan. Since then, two new high-capacity production systems have started operation, helping Buzios to also reach a daily production of 1 million barrels of oil. An additional five FPSOs are scheduled to begin operation by 2027, positioning Buzios as the largest ultra–deep-water oil field in the world.
Fabiano holds a B.S. in Mechanical Engineering from Universidade Federal do Rio de Janeiro (UFRJ) and an MBA in Oil and Gas Management from Fundação Getulio Vargas (FGV). He currently serves as Reservoir Manager for Buzios Field at Petrobras, where he focuses on optimizing reservoir performance and supporting the long-term strategic development of one of the most significant offshore assets globally.

During exploration, several wells showed excellent productivity, indicating around 34 billion boe in place, making Buzios the largest ultra-deepwater oil field globally. To exploit the additional volumes, in November 2019, the Brazilian government held the ToR surplus bidding round, with Petrobras and Partners CNOOC and CNODC winning the right to exploit the Field without volume limits until 2055. A new Global Development Plan (GDP) was defined, including 7 additional FPSOs, totaling 12 production units.
In February 2025 the 6th FPSO started production, and the 7th to 11th units are under construction, planned to start operation until end 2027. The 12th module is under study, with the objective to increase the production of the Field, as well as providing more gas to the market.
As Operator and Partners work to implement the GDP, focus is also being put on the future of the Field, with the goal of boosting production through the adoption of new technologies and initiatives, while also investing to increase energy availability, operational efficiency and reduce emissions.
Innovative subsea water injection systems are being implemented to enhance oil recovery and sustain reservoir pressure. Furthermore, plans for new infill wells are being devised to access undrained areas of the reservoir. To support these initiatives, Petrobras and Partners are investing in cutting-edge reservoir monitoring technologies, including 4D Seismic and well monitoring utilizing Distributed Acoustic and Temperature Sensing (DATS). Additionally, in order to increase the energy availability, thus increasing operational efficiencies, Petrobras is studying to electrically connect platforms through submarine power umbilical.
In alignment with the Net Zero by 2050 Petrobras ambition, several technologies are being incorporated, such as flare gas recovery units, carbon capture, utilization, and storage associated with enhanced oil recovery, operational venting recovery systems and low-emission fugitive valves.
For the long-term of the Field, studies are being carried out to ensure the integrity of the facilities and extend the life span of the current units.
With those innovative technologies and initiatives, Petrobras, Partners and PPSA intend not only to extract the best value of the Field in the present, but also guarantee a long-term production, maximizing the value of the world’s largest ultra-deepwater oil field.
