Tullow has a track record of discovering significant oil resources in East Africa. The Group first started exploring in Uganda in 2006, successfully opening the Lake Albert Rift Basin, which has discovered resources of some 1.7 billion barrels of oil. Tullow has taken its knowledge and understanding of the geology in Uganda across into neighbouring Kenya. Since 2012, Tullow’s successful exploration and appraisal drilling campaigns in Kenya have resulted in the opening of a second new tertiary rift play in the South Lokichar Basin. An accelerated exploration and appraisal campaign was completed in the basin and initial assessment indicates recoverable resources of up to 750 million barrels of oil.
The Ngamia-1 exploration well in Kenya marked the start of a significant programme of drilling activities across the acreage. In 2012, the Ngamia-1 well successfully encountered over 200 metres of net oil pay, the second East Africa onshore tertiary rift basin opened by Tullow. This has since been followed by further exploration success in the South Lokichar Basin at the Ngamia, Twiga, Etuko, Ekales-1, Agete, Amosing, Ewoi, Ekunyuk, Etom, Erut and Emekuya oil accumulations. The current phase of exploration and appraisal drilling in the South Lokichar Basin has been concluded and the focus is now on the Early Oil Pilot Scheme (EOPS) and the development of the discovered resources.
