Afren Energy Resources Ltd. has extended its contracts for use of the Armada Perkasa floating production, storage, and offloading vessel on the Okoro-Setu oil field complex offshore southeastern Nigeria (OGJ Online, Oct. 31, 2012).
The 2-year extension covers the bareboat charter with Armada Floating Solutions Ltd. and the operations and maintenance contract with Bumi Armada (Singapore) Pte. Ltd., both units of Bumi Armada Bhd. of Malaysia.
The 211.2-m long, 58,557 dwt FPSO has been operating for Afren and Amni International Petroleum Development on the OML 112 permit since 2008. It has production capacity of 27,000 b/d and storage capacity of 360,000 b/d. It so far has handled more than 32 million bbl of oil.
Afren operates the permit in partnership with Amni International Petroleum Development of Nigeria under a financing and production sharing and technical services agreement signed in 2006. Post-cost recovery interests are 50% each. Okoro was discovered in 1973 by Japan Petroleum. Setu, 7 km north of Okoro, was discovered by Amni in 2002.
During this year’s first half, Okoro produced an average 17,815 b/d of oil.
The field now has a wellhead platform that produces into the FPSO. A shuttle tanker carries processed crude to the Ima terminal operated by Amni.
Afren and Amni plan a new wellhead platform and production unit to expand Okoro development. The platform will be a conventional, four-pile installation with a single-piece jacket and deck able to accommodate wireline and coil tubing units. The platform, bridge-linked to the existing main wellhead platform, will have 12 well slots able to hold dual trees.
