Afren eyes further Ebok expansion offshore Nigeria

Production from the shallow-water Ebok field offshore Nigeria has averaged more than 35,100 b/d of oil, boosted by three new development wells.

LONDON – Production from the shallow-water Ebok field offshore Nigeria has averaged more than 35,100 b/d of oil, boosted by three new development wells.

Two were drilled in the north fault block (NFB) and one in the west fault block (WFB). A water injector well to spud soon will is designed to optimize and support the existing NFB producers.

OperatorAfren expects the central fault block extension platform to be installed in early 2014, and the partners will target additional reservoirs in this area. They are considering further options for the NFB, which could mean drilling development wells from an extended WFB platform, with production achieved through Ebok’s existing mobile offshore production unit.

Following completion of an ocean bottom cable 3D seismic program over the whole Ebok/Okwok/OML 115 license, Afren has firm plans for a first exploratory well early next year on the Ufon structure. TheGSF Monitor will drill this potential 65-MMbbl prospect, which Afren says is structurally and geologically analogous to Ebok and Okwok.

Elsewhere off Nigeria, the OML 113 partners are considering drilling and early production on the Aje field, and there may be development synergies with theOgo discovery in OPL 310, Afren adds.

In the Tanga block offshore Tanzania, Afren is interpreting final processed data from a 620-sq km (239-sq mi) 3D seismic survey. Simultaneously, the company and its partners are working up the shallow-water Chungwa-1 prospect and the deeper-water Mkonge-1.

They are lining up a rig to drill two wells, starting with Chungwa-1 early next year. This will test Tertiary, Cretaceous, and Jurassic reservoirs, targeting P50 oil resources of 210 MMbbl.
