Project Description
Located on Block OPL 222 in the Gulf of Guinea, offshore Nigeria, Africa, is the Usan field. The field is situated in water depths ranging from 2,461 to 2,789 feet (750 to 850 meters), and has proven and probable reserves of 500 million barrels of oil.

Total's subsidiary, Elf Petroleum Nigeria Limited, operator, owns a 20% interest in the field; Chevron Nigeria Limited owns 30%; Esso owns 30%; and Nexen owns the remaining 20% interest.

Discovered in 2002, the discovery well was drilled to a depth of 8,940 feet (2,725 meters), and is situated roughly 60 miles (97 kilometers) off the coast of Nigeria. The well was drilled by Saipem's semisubmersible, Scarabeo 7.

The field was also confirmed by two appraisal wells, which revealed light, crude oil in multiple pay zones. In 2004, a western extension of the field was confirmed by the drilling of the Usan 5 and 6 wells. In 2005, an eastern extension was discovered on the Usan field when an additional two extension wells, Usan 7 and 8, were drilled.

Field Development

The Nigerian National Petroleum Corp. (NNPC), concessionaire of the license, approved the field development in 2008. The field development will consist of 23 production wells and 19 water and gas injection wells tied-back to an FPSO with a storage capacity of 2 MMboe.

Cameron was awarded a contract worth US $650 million to provide subsea systems for the Usan field. The contract encompasses engineering of the subsea systems and project management, along with subsea xmas trees, production and intervention control systems, manifolds, flowline connection systems, and installation support.

Saipem was awarded a contract, worth $1.3 billion, for the umbilicals, flowlines, risers and oil loading terminal activities for the subsea development of the field.

Acergy will fabricate, assemble and test eight manifolds and support structures, eight suction piles, 23 well jumpers and other subsea structures for the field. The contract is worth $50 million.

In February 2008, Hyunday Heavy Industries Co. received a letter of award from Elf Petroleum Nigeria, worth $1.6 billion, to construct an FPSO. Located on the Usan field, the vessel will weigh 114,000 tons (103,419 tonnes), measure 1,050 feet (320 meters) in length, 200 feet (61 meters) in width and 105 feet (32 meters) in depth. Construction of the FPSO should end in the fourth quarter of 2011.

Aker Solutions was awarded a contract for the supply of offshore loading systems and deck machinery - the total value of the contract is worth $9 million (NOK 70 million).

The field came online on February 24, 2012 and should reach peak production of 180,000 bopd.
