Recoverable resources set to surpass expectations on OPL 310 block offshore Nigeria

Recoverable resources set to surpass expectations on OPL 310 block offshore NigeriaThe Ogo-1 well was targeting 78 mmboe of gross P50 prospective resources, Lekoil said.

Based on data from the Ogo-1 well, the partners estimated the P50 to P10 gross recoverable resources range to be significantly ahead of pre-drill expectations at 774 to 1,180 million barrels of oil equivalent (mmboe) across the Ogo prospect four-way dip-closed and syn-rift structures.

Lekan Akinyanmi, CEO of Lekoil, said, “Today’s announcement confirms a very significant upgrade to the resources at Ogo compared with our pre-drill expectations. We will continue to work with our partners to progress the Ogo discovery while also focusing on examining other opportunities to build our portfolio of assets. Ogo has provided us with a flying start to our strategy to build a substantial, Africa-focused oil and gas business.”

According to Lekoil, pre-drill evaluation of the OPL 310 block, which is located in the Upper Cretaceous fairway that runs along the West African Transform Margin, identified several prospects lying in Turonian, Cenomanian and Albian sandstone intervals.
The Ogo-1 well was targeting 78 mmboe of gross P50 prospective resources, Lekoil said.

The well was drilled to a total measured depth of 10,518 ft and encountered a gross hydrocarbon section of 524 ft, with 216 ft of net stacked pay. The planned side-track well (Ogo-1 ST) reached a total measured depth of 17,987 ft and encountered hydrocarbon intervals in the same reservoirs that were successfully drilled and logged at the Ogo-1 well, Lekoil said.

In addition, the syn-rift section encountered a 280 ft true vertical thickness gross hydrocarbon interval, it said.

Whilst circulating bottoms up at TD, the drill string parted at 3,390 ft and, during good progress towards recovery of the drill string from the well bore, the well took a hydrocarbon kick, Lekoil said.

After the kick was safely controlled, the partners considered it prudent to move to permanently secure the well, it added.

Lekoil said it intends to drill an appraisal well with its partners in the second half of 2014 to increase 3D coverage, which currently covers only 25 per cent of the block.

Lekoil and Optimum Petroleum Development each hold a 30 per cent stake in the OPL 310 block, while Afren holds a 40 per cent interest.
