Petrobras Albacora

Petrobras Albacora


Landmark: Brazil’s first developed giant field

In 1984, the Albacora field was discovered at Campos Basin, proving the existence of giant deepwater fields in Brazil. The Albacora field comprises 65 wells, two production units (semisubmersible P-25 and FPSO P-31) and seven diverless manifolds (six for oil production and one for water injection). The production has reached 150,000 bopd and 90 mmcf/d of natural gas.

The semisubmersible platform P-25 has a process plant with the capacity of 100,000 bopd and 115 mmcf/d of natural gas. There are 14 production wells connected directly to the platform (satellite wells) and 16 wells connected to two diverless production manifolds by a vertical flowline connection system. These FMC Technologies manifolds, installed in December 1995 and April 1996, were the world’s deepest subsea production manifolds and multiplex control pods at the time.

The FPSO P-31 process plant capacity is 200,000 bopd and 130 mmcf/d of gas. The plant processes the oil produced in P-25 platform and the oil production of 28 production wells connected to four FMC Technologies production diverless manifolds.
