In its 2024 exploration roundup, Welligence highlighted several key upstream developments in sub-Saharan Africa, including Namibia's Mopane discovery, the largest of the year, which requires further appraisal drilling to refine its liquid-to-gas split. Other notable discoveries include the Calao discovery in Ivory Coast – estimated at around 500 million barrels of oil equivalent – and Enigma and Mangetti in Namibia, both of which are under 500 million barrels and require further appraisal drilling. According to Welligence, additional developments to watch include TotalEnergies' Niamou Marine-1 exploration well offshore Congo, ExxonMobil's Arcturus wildcat in the deepwater Namibe Basin in Angola, and Apus Energy's Atum prospect in deepwater Guinea-Bissau.
