Petrobras Marlim Sul

Marlim Sul


Landmark: Petrobras Marlim Sul is FMC Technologies CBV’s first generation of horizontal subsea trees.

The Marlim Sul field was discovered in November 1987 in water depths ranging from 2,640 to 8,600 ft (800 to 2,600 m). This 230 mile2 (600 km2) field lies 72 miles (120 km) off the coast of Rio de Janeiro. Petrobras adopted a pilot and phased production approach for field development. This approach has the combined benefits of earlier production and relevant data collection, thus reducing the economic risks of future field developments.

In April 1994, MRL-4 well established a deepwater production record at a water depth of 3,389 ft (1,027 m). Another record was established in August 1997 from Module 4, through MLS-3 well, in 5,639 ft (1,709 m) of water, which produced to the FPSO-II. This system, with capacity to process and store 30,000 bopd, operated up to October 1998, when data collection was finalized. FPSO-II was then repositioned for a new pilot system.

Module I of the Marlim Sul field development includes a total of 35 wells: 21 producers and 14 water injectors. All these wells are subsea direct satellites, linked through individual bundles to the semisubmersible P-40, which has the capacity to produce and process up to 155,000 bopd.

Module II is under technical and economical evaluation. Present plans consider a system for 180,000 bopd, comprising 14 oil producers and 10 water injectors in up to 4,950 ft (1,500 m) water depth.
