Brazilian government-backed oil company Petrobras has commenced production from the FPSO Anna Nery in the Campos Basin.

The FPSO is part of the revitalisation project for the Marlim and Voador fields, and Brava, located in the pre-salt of the two fields.

The vessel is designed to produce up to 70,000 barrels of oil per day and process four million cubic metres of gas.

Petrobras CEO Jean Paul Prates said: “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.”

Together with the Anita Garibaldi, also an FPSO, the Anna Nery unit makes up the first major revitalisation project for mature fields in the Campos Basin.

“The deployment of these two new production systems, appropriate to the mature field exploration format, provides operational continuity to the Marlim and Voador fields, increasing production to an average of 150,000 barrels of oil equivalent per day (boed),” the Brazilian energy major said in its press statement.  

Anchored in a water depth of 927m, Anna Nery is interconnected to 32 wells.

 The unit is expected to achieve peak production capacity in 2025.

The average daily production from Petrobras’ assets in the Campos Basin is currently at 560,000boed, and is expected to reach 900,000boed in 2027.

Recently, reports emerged that Petrobras may relocate a rig it has built to drill at the mouth of the Amazon River Basin to another site if it does not get environmental clearance to operate there.

It also recently abandoned plans to sell its stake in the Tayrona block off the coast of Colombia.
