ExxonMobil Begins Development of Yoho Offshore Project in Nigeria

August 29, 2002 at 10:31 AM EDT
IRVING, Texas, Aug 29, 2002 (BUSINESS WIRE) -- Exxon Mobil Corporation (NYSE:XOM) announced today that its subsidiary, Mobil Producing Nigeria Unlimited (MPN), has started development of the Yoho project offshore Nigeria.

The $1.2 billion project, located in the Nigerian National Petroleum Corporation (NNPC)/MPN Joint Venture acreage, Oil Mining Lease (OML) 104, has estimated recoverable resources of 0.4 billion barrels of oil. Yoho will develop discoveries in the Yoho and Awawa reservoirs in shallow water depths of 200-300 feet.

A special feature of the Yoho project is the Early Production System (EPS) which will temporarily utilize a Floating Production Storage and Offloading (FPSO) vessel to produce first oil almost two years ahead of full-field start-up. Production will begin in late 2002 from an initial wellhead platform producing through the FPSO and is expected to add about 90,000 barrels of oil a day.

Full-field start-up is scheduled for late 2004 and will include additional wellhead platforms, a central production platform, a living quarters platform, and a Floating Storage and Offloading (FSO) vessel, which will replace the FPSO. Target peak production is 150,000 barrels of oil per day. Produced gas will be re-injected to maximize oil recovery and eliminate routine flaring.

"The commencement of Yoho construction activities, including the first deployment of an EPS in West Africa, represents an important milestone for ExxonMobil in Nigeria," said Rex Tillerson, senior vice president, Exxon Mobil Corporation. "The ability to advance production, as we will do with Yoho by over two years, not only improves the project's economics but also meets the government's objective of increasing production capacity."

MPN has awarded construction and fabrication contracts valued at more than $400 million for offshore facilities for Yoho. The project is contributing both direct and indirect benefits to the Nigerian economy through project spending and employment. Local contractors will be used for significant aspects of the development including fabrication of jackets, bridges and pipe coatings for the main offshore facilities.

MPN holds a 40 percent interest in the NNPC/MPN Joint Venture, which has a current production capacity of approximately 650,000 barrels per day of petroleum liquids. The Federal Government of Nigeria holds the remaining 60 percent interest through the NNPC.

In Nigeria, ExxonMobil subsidiaries hold interests in six deepwater blocks covering 3.2 million acres. Deepwater discoveries in Nigeria include Erha located in OPL 209 (56.25 percent interest), Bonga and Bonga Southwest in OML 118 (20 percent interest), Bolia in OPL 219 (20 percent interest), Chota in OPL 220 (47.5 percent interest) and Usan in OPL 222 (30 percent interest).

ExxonMobil is a leader in the discovery and development of deepwater hydrocarbon resources in West Africa, where it has interests in 18 blocks totaling more than 16 million gross acres. The company has a leading position in nearly all the major exploration and production areas in the world, the industry's strongest portfolio of proprietary technology and is the leading developer of world-class geoscience and engineering technology.

CAUTIONARY STATEMENT: Estimates, expectations, targets, and business plans in this release are forward-looking statements. Actual future results, including resource recoveries, production rates, and project plans and schedules, could differ materially due to changes in market conditions affecting the oil and gas industry, technical or operating factors, and other factors discussed under the heading "Factors Affecting Future Results" included in Item 1 of ExxonMobil's most recent Form 10-K and posted on our website (www.exxonmobil.com). References to recoverable resources include quantities of discovered oil and gas that are not yet classified as proved reserves but that we believe will be produced in the future.
