||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. The following well at Tutule-1 recorded gas shows and reaffirmed the presence of hydrocarbons in the region. These were the most northerly wells drilled in our East African acreage at the time, and importantly established that the hydrocarbon system is present. Numerous additional follow-up prospects have been mapped in this part of the South Omo Block.
A second exploration campaign was carried out to the East in the Chew Bahir Basin. The Shimela and Gardim wells were drilled in 1H 2014 and neither found commercial hydrocarbons. Seismic interpretation continues on independent prospectivity in other sub-basins elsewhere in the licence and the next phase of our Ethiopia exploration campaign will target these prospects.
