HOUSTON, Mar. 7 -- Fabrication is complete on Elf Petroleum Nigeria Ltd.'s 12,125 tonne Amenam-Kpono AMP1 production platform, which is en route on its 7,360-mile journey from J. Ray McDermott SA's Jebel Ali fabrication facility in Dubai to Amenam field 19 miles off Nigeria.
The platform, for installation in 131 ft of water, will have a processing capacity of 130,000 b/d of oil, with 15 million cu m/day of gas injection and 12,500 cu m/day of water injection capability.
The integrated deck is the "largest deck ever built in the (Persian) Gulf," said McDermott, which fabricated the AMP1 jacket and deck under a subcontract from the Saibos CML-led consortium that has the turnkey contract for engineering, procurement, construction, and installation of the platform (OGJ Online, Sept. 13, 2000).
The jacket, with 3,700 tonnes of associated equipment, was completed at the Jebel Ali yard in December 2002.
The deck, constructed as a single piece, comprises a weather deck, mezzanine deck—built as separate deck levels of 1,000-1,500 tonnes each—and main deck, with an additional, smaller cellar deck, and an integrated four level building. McDermott completed the jacket and deck within 23 months by fabricating three decks simultaneously.
Elf expects initial production of 125,000 b/d by mid-2003, and production is expected to total 500 million bbl over 25 years. Reserves are estimated at more than 1 billion boe (OGJ Online, Mar. 26, 2001).
Out of the 16.5 million cu m/day of associated gas, 15.6 million cu m/day will be reinjected to enhance oil recovery.
Elf is operator on behalf of the state-run Nigerian National Petroleum Corp. and Mobil Producing Nigeria Unlimited, a subsidiary of ExxonMobil Corp.
