Petrobras started production from the floating production, storage, and offloading (FPSO) vessel Anna Nery on 7 May in the Campos Basin offshore Brazil.
The Brazilian oil giant said on Monday that the unit is one of two FPSOs set to revitalize production of the Marlim, Voador, and Brava fields. Production from the Marlim and Voador fields is from post-salt reservoirs, while production from the Brava field is from the reservoir located in the pre-salt of the two fields, according to Petrobras.
The FPSO Anna Nery can produce up to 70,000 B/D of oil and 4 million m3 of gas per day. The unit, chartered by Petrobras in 2019, was built in Cosco Changxing, China. The unit is anchored in a water depth of 927 m and interconnected to 32 wells, with peak production scheduled for 2025.
"This is the largest project in the world in the recovery of mature assets in the offshore industry. Through it, we will increase production, maintain jobs, and open an important learning and knowledge front for other similar projects throughout Brazil," said Jean Paul Prates, chief executive of Petrobras.
The FPSO Anna Nery, together with the FPSO Anita Garibaldi, make up what Petrobras has called the “first major revitalization project for mature fields in the Campos Basin.”
The FPSO Anita Garibaldi recently departed a shipyard in the state of Espírito Santo where its final commissioning occurred bound for the Campos Basin. Production start is scheduled for the third quarter of 2023. It has the capacity to produce up to 80,000 B/D of oil and up to 7 million m3 of gas per day. It will be connected to 43 wells, with peak production scheduled for 2026.
The Marlim and Voador revitalization project will contribute to the recovery of the Campos production, currently at about 560,000 BOE/D. The projection for the basin's production is 900,000 BOE/D in 2027.
