Oil discovery offshore Nigeria on the OPL 310

Lekoil announced that the high impact Ogo-1 well located on the OPL 310 licence offshore Nigeria has discovered a significant light oil accumulation, based on the results of drilling and wireline logs.
The Ogo-1 well is being drilled by Afren Plc (“Afren”), as technical partner, under a farmout to Lekoil of OPL310, offshore Nigeria (“OPL310”), as announced on 14 May 2013. The well has been drilled to a total measured depth of 10,518ft (10,402ft true vertical depth subsea (“TVDSS”)), and has encountered a gross hydrocarbon section of 524ft, with 216ft of apparent stacked,
net pay.
Further wireline log evaluation is currently underway prior to extending the well to target deeper prospectivity above basement, to a total measured depth of 11,800ft (11,684ft TVDSS). The expected timetable for completion of this further drilling together with additional testing is four to six weeks (inclusive of drilling a planned Ogo-1 side-track well).
The Ogo-1 discovery, testing a four-way dip-closed structure in the Turonian, Cenomanian, and Albian sandstone reservoirs, confirms the extension of the same Cretaceous play that has yielded other significant discoveries along the West African Transform Margin.
The results also indicate a working hydrocarbon system that is weighted more towards liquids than gas. This has been confirmed by MDT samples; light oil samples in the Turonian and Cenomanian sands and condensate samples in the Albian sands.
