HRT has retained operatorship of these PELs.In March, HRT Africa spudded the Wingat-1 (2212/07-1) wildcat well, the first offshore well in our 3-wellback-to-back exploratory drilling campaign. The Wingat Prospect is located in PEL 23, approximately 200km northwest of Walvis Bay, in 1,034 meters of water depth.The main objective of the well was to test the resource potential of the Albian (Cretaceous) carbonateplatform that has a well-defined seismic amplitude anomaly in the PSDM-3D data set.HRT forecasts that the current activities in the Wingat-1 well will be concluded next week.| Page 8 |
