||Acreage (sq km)
Following Tullow’s exploration success to date in Uganda’s Lake Albert Rift Basin, the company has extended its exploration acreage into the prospective East African Rift Basins of Kenya and Ethiopia.
In 2010, Tullow signed an agreement with Africa Oil to gain a 50% operated interest in the South Omo Block in Ethiopia. This has been complemented by the 50% operated interests in six adjacent Kenyan licences. The combined acreage covers the Turkana Rift Basin which is similar in geology to the Lake Albert Rift Basin and is also a south-east extension of the geologically older Sudan rift basins trend. The first well in the licence commenced in December 2012 at Sabisa-1. This is the most northerly well drilled in our East African acreage to date, and established that the hydrocarbon system in that area is oil prone. The well has encountered reservoir quality sands, oil and heavy gas shows indicating an oil prone source rock and a thick shale section which should provide good seals for the numerous fault bounded traps identified in the basin. Following this encouraging result, the decision has been taken to drill the nearby Tultule prospect, an attractive structure four kilometres east of Sabisa-1. The well commenced drilling in September 2013. Numerous additional follow-up prospects have been mapped in this part of the South Omo Block and in the adjacent Chew Bahir Basin.
