The location is 53 miles (85 km) off the coast, situated in 328 to 390 feet (100 to 119 m) of water. Peregrino is a heavy crude oil of 13. API and with high viscosity. Sulfur content is 1.8% which is considered medium sour. The estimated recoverable volume of crude oil is 300 million barrels (48×10 6 m3) to 600 million barrels (95×10 6 m3). The first oil is expected for early 2011, where 5 wells are anticipated for production and production should reach a plateau of 100,000 barrels per day (16,000 m3/d) within the first year with a targeted production of some 120,000 barrels per day (19,000 m3/d) by 2012. The field will be completed in three phases and will include approximately 60 wells; phase one of the project includes 37 wells; 30 production wells and 7 water injection wells. The temperature of the oil, gas, water and sand from the field is 79.6°C in the reservoir and 60-66°C on arrival in the ship, and then heated to 130-150°C for processing (separation). After this, the temperature is kept at 65-70°C to keep the oil liquid.[1]
Development

The field was originally planned to be operated by
The first phase of the development includes two drilling and wellhead platforms and a ship-shaped floating production, storage and off-take unit (
The platforms are tied back to the FPSO by flowlines and power umbilicals. Project requires extensive sub-surface and reservoir management skills such as produced water injection, horizontal wells and flow assurance to sustain the project over a longer-term.
With the current reservoir depletion plan of the field calling for the use of produced water injection and rock compaction, Peregrino's recovery factor has increased to 20%.[3]

The project commenced in February 2007, when South Atlantic Holding and Maersk Contractors signed an agreement to perform a FEED study for the project. Shortly after the FEED, a contract was awarded to Maersk Contractors (now Maersk FPSOs) for the provision of the FPSO and for 15 years of operation of the FPSO.
Aker Solutions will perform the mooring installation work – the first marine installation job for Aker Solutions in Brazil. The scope of work comprises planning and installation of a submerged turret production (STP) buoy with mooring system using ten mooring lines with 90-tonne piles, heavy chain and wire. The operations were scheduled to be conducted during Q4 2009.[needs update]
APL (a subsidiary of
Kiewit Offshore Services was selected for the engineering, procurement, and construction of the two large 6,500-ton decks and two jackets, 6,600 and 7,000 tons respectfully. Additional scope also includes the fabrication of two piles weighing a total of 5,600 tons.
Subsea 7 received a contract for the engineering, procurement, construction and installation of the pipelines connecting the two platforms to the FPSO. Another contract was awarded to Kiewit Offshore Services Ltd. for the supply of two drilling platforms for the field.
FMC Technologies will manufacture and install the surface wellheads and surface production trees for the Peregrino project.
William Jacob Management, Inc. were awarded the engineering, procurement and construction management[4] by Statoil for the provision of the drilling facilities.
Siem Consub will provide maritime support for the initial 2 years under a renewable contract for an additional year. The PSV-ship will be available beginning in the first quarter of 2010. Seawell, a Seadrill subsidiary, will manage the drilling campaign at a cost of US$90 million.
