Project Profile
Location: Oil Mining Lease (OML 140), Nigeria
Production: 100,000bpd
Water Depth: 1729 m
Total Depth: 4257 m
The oil field would be produced using a Floating Production Storage and Output (FPSO) facility. Nsiko block is located in Oil Mining Lease (OML 140). Nsiko was discovered in 2003 with Nsiko-1, drilled to a total depth of 4257metres, in 1729 metres of water, hosting a substantial amount of crude oil. One zone was tested in the well and flowed at 6,500 barrels of high quality crude per day under restricted flow conditions. Chevron operates and has a 100% interest in the Nsiko discovery in OML 140. The project is expected to produce 100,000bpd.
There is an option that Chevron Nigeria and ExxonMobil would jointly develop Nsiko and Uge oil blocks in Nigeria’s continental oil shelves. Efforts to enhance the probability of Uge development are being investigated by the licence partners. A joint development with the adjacent oil field Nsiko and a shared FPSO was investigated with emphasis on the basis of design and cost estimates. If the option is validated, the FPSO will be stationed midway between the two fields.
Uge is located in OML 145 and operated by Esso Exploration & Production Nigeria (Deepwater West) Ltd while Nsiko is located in an adjacent undeveloped block (OML 140) operated by Star Ultra Deep Petroleum Ltd (a Chevron company) about 50 km apart; both with a resource size of approximately 300 mmboe.
