News Release

Kenya onshore exploration success continues with the Agete-1 oil discovery

22 November 2013 - Tullow Oil plc (Tullow) announces that the Agete-1 exploration well in Block 13T, onshore Northern Kenya, has discovered and sampled moveable oil with an estimated 100 metres of net oil pay in good quality sandstone reservoirs.

The Agete-1 wildcat well is part of a major exploration campaign and has made the fifth consecutive oil discovery in the first of a chain of multiple rift basins across Tullow's acreage in the region. This discovery de-risks several follow-on prospects located to the north and is on trend with the Twiga South, Ekales, and Ngamia oil discoveries and adds to the significant resource base already discovered.

The Sakson PR5 rig drilled Agete-1 to a total depth of 1,930 metres. Following completion of logging operations the well will be suspended for future flow testing which will confirm the net pay count. The rig will then move to drill the Ewoi-1 wildcat in the east of this basin, targeting a rift flank prospect similar to the recent Etuko oil discovery.

Tullow operates the Agete-1 well with a 50% interest and Africa Oil (50%) has a non-operated interest.

Elsewhere in Kenya, exploration and appraisal activities continue to accelerate with the Amosing-1 well, in Block 10BB, expected to commence drilling before the end of November with the Weatherford 804 rig. The Etuko-1 well test in Block 10BB is also scheduled to commence this month with the PR Marriott 46 rig which recently arrived in country and the Ekales-1 well test is scheduled to commence with the new SMP-5 workover unit in early December.

Angus McCoss, Exploration Director, Tullow Oil plc commented today,

"A fifth consecutive oil discovery onshore Northern Kenya highlights the emerging world class exploration and production potential within our rift basin acreage. An intensive campaign for 2014 includes appraisal and exploration within this first basin and pioneering wells targeting the prospectivity throughout the entire chain of similar rift basins."
