The Usan field is located 110 kilometers offshore in water depths of approximately 800 meters. The field was discovered in 2002. In 2004, a western Usan extension was confirmed by the drilling of Usan 5 and 6. This year, Usan 7 and 8 confirmed an eastern extension of the Usan field. Both wells were drilled using Transocean's semisub, M G Hulme, Jr.
The Field Development Plan has been approved by NNPC, the concessionaire of the license. Additional approval will be sought from the Department of Petroleum Resources in the near future. The plan features a development of the Usan field with 35 subsea wells connected to a 2 million barrel capacity floating production storage and offloading (FPSO) by subsea lines and risers. The processing capacity is around 150,000 barrels of oil per day. First oil is planned by 2010.
NNPC is concessionaire for OPL 222 under a Production Sharing Contract operated by Elf Petroleum Nigeria Ltd. (20%), in partnership with Chevron Petroleum Nigeria Ltd. (30%), Esso Exploration and Production Nigeria (Offshore East) Ltd. (30%) and Nexen Petroleum Nigeria Ltd. (20%).
Present in Nigeria since 1962, Total's equity production was 271,000 barrels of oil equivalent per day in 2004. The Group recently launched the development of the deep offshore Akpo field which will enter into production late 2008 at a plateau of 225,000 barrels of oil equivalent per day. Total also holds a 15% partnership interest in the Bonny gas liquefaction plant, where train four will come on stream by the end of this quarter and train five before the end of this year.
