Comments

In 1984, the Albacora Field was discovered at Campos Basin, proving the existence of giant deepwater fields in Brazil. The Albacora Field comprises sixty-five (65) wells, two (2) production units (semisubmersible P-25 and FPSO P-31) and seven (7) diver-less manifolds (6 for oil production and 1 for water injection). The production has reached 150,000 bopd and 90 mmcf/d of natural gas.

The semi-submersible platform P-25 has a process plant with the capacity of 100,000 bopd and 115 mmcf/d of natural gas. There are fourteen (14) production wells connected directly to the platform (satellite wells) and sixteen (16) wells connected to two (2) 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 twenty-eight (28) production wells connected to four (4) FMC Technologies production diverless manifolds.
