LONDON -- Afren’s Ebok Deep exploration well off southeast Nigeria has encountered oil shows.
Analysis of the drilling results and wireline logs suggests the well intersected two sandstone intervals with 370 ft (113 m) combined thickness in the Biafra and Isongo formations.
The oil shows indicate oil migration, Afren claims, with potential for oil being trapped up-dip from the current well location.
The well, which was drilled to a TVD of 10,085 ft (3,074 m) in the OML 67 offshore license, has been abandoned temporarily for potential re-use.
Afren says the outcome has demonstrated a working hydrocarbon system in the deeper Biafra and Isongo formations, with high quality reservoir sands. It plans to incorporate the well data into a sub-surface model to assist exploration of the deeper horizons at the Ebok and Okwok fields and adjoining OML 115.
Over the rest of 2010, the company says it is various high impact exploration and appraisal wells, initially at Okwok and OML 115.
