Lekoil in its operational update on the development of the OPL 310 block which contains the Ogo oil discovery, offshore Nigeria.

Located in the Upper Cretaceous fairway that runs along the West African Transform Margin, the OPL 310’s main prospects besides the Ogo discovery are in water depths from 100 to 800 meters and are not far from the West Africa Gas Pipeline.

In 2015, Lekoil increased its interest in the concession to 40%, following the acquisition of one of the licences from Afren Oil and Gas.

Ogo-1 encountered a gross hydrocarbon section of 160 meters, with 66 meters of net pay while the Ogo-1 ST well came across the same reservoirs as Ogo-1.

In line with the data gathered from the two wells, the partners expected a 2P gross recoverable resource at 774 Mmboe throughout the Ogo prospect’s four-way dip-closed and syn-rift structure.

However, because of the block’s size, the OPL 310 partners have agreed to obtain a 3D seismic so as to high grade and de-risk other prospects adjacent to Ogo.

Lekoil and its partner Optimum are currently planning to drill an appraisal well in 2017.

“The discovery of oil in the Ogo-1 well opens up a new oil basin in an under-explored region and represents a possible extension of the Cretaceous play along the West African Transform Margin.  The discovery is a clear validation of Lekoil’s technical analysis and of our extensive studies on the Dahomey Basin,” Lekan Akinyanmi (photo), CEO of Lekoil, told Business Day.
