Ogo is a large oil and gas discovery located in shallow water offshore Lagos. Discovered in 2013 Ogo lies in the Keta Togo Benin Basin and yielded a P50 reserves estimate of 770 mmboe well in excess of the pre drill 200 mmboe estimate. In May 2014 a large 3D seismic survey was carried out over OPL 310 and OML 113. Within OPL 310 the survey covered 1 505 square kilometres equating to 80% of the block's acreage. Interpretation of the results commenced in H2 2014 and have now been completed. Although Ogo is a large discovery and potentially very valuable the collapse of Afren and the current absence of an experienced technical operator means we have downgraded it to a technical reserve.
