ExxonMobil Corp.'s subsidiary, Mobil Producing Nigeria Unlimited (MPN), has started production from the Yoho development in the Nigerian National Petroleum Corp. (NNPC)/MPN joint venture (JV) acreage, Oil Mining Lease (OML) 104, offshore Nigeria.
The $1.2 billion project, with estimated recoverable resources of 0.4 Bbbl, will develop discoveries in the Yoho and Awawa reservoirs in shallow water depths of 200-300 ft. By using a temporary FPSO vessel as an early production system (EPS), first oil from Yoho came onstream almost two years ahead of full-field start-up. Production through the FPSO is expected to add over 90,000 b/d.
"Yoho is the first of several significant, new development projects, operated by ExxonMobil, to come onstream offshore West Africa," said Rex Tillerson, senior vice president, Exxon Mobil Corp.
The full-field development will involve additional wellhead platforms, a central production platform, a living quarters platform, and an FSO vessel, which will replace the EPS. Full-field start-up is scheduled for late 2004. Yoho will serve as a hub for future development of OML 104 petroleum resources.
ExxonMobil's subsidiary, MPN, holds a 40% interest in the NNPC/MPN JV, which has a production capacity of 650,000 b/d of petroleum liquids. The Federal Government of Nigeria holds the remaining 60% interest through NNPC.
