In 2013, the first exploration well (Ogo-1) drilled by the OPL 310 partners - then consisting of Optimum, LEKOIL and Afren - was the Ogo prospect, a four-way dip-closed structure in the Turonian to Albian sandstone reservoirs. The drilling programme included a planned side-track well (Ogo-1 ST) which aimed to test a new play of stratigraphically trapped sediments at the basement of the Ogo prospect. The Ogo-1 well encountered a gross hydrocarbon section of 524ft, with 216ft of net stacked pay whilst the Ogo-1 ST well encountered the same reservoirs as Ogo-1 in addition to the syn-rift section which encountered a 280 ft vertical section gross hydrocarbon interval. Owing to well data collected from the two wells, the partners estimated P50 gross recoverable resources to be at 774 mmboe across the Ogo prospect four-way dip-closed and syn-rift structure.
