Tullow Oil Spuds Kenya Well

Africa Oil Corp. announced that Tullow Oil Plc, the operator of Block 10BB in Kenya, has commenced drilling at the Etuko (formerly Kamba) prospect. This well will target a new play area in the Lockichar Basin where a working petroleum system has been confirmed by recent discoveries at Ngamia and Twiga. The well will focus on the 'eastern flank play' where oil was discovered in 1992 by Shell at the Loperot-1 well. The primary objectives will be the Lower Lokhone and Auwerwer sands, both of which have been shown to be high quality reservoirs containing oil in existing wells. The gross best estimate of prospective resources for the prospect are 231 million barrels of oil based on a third-party Competent Person's Report. The well is expected to take approximately 60 days to drill and evaluate.

Testing operations continue on the Ngamia #1 well, also in Block 10BB in Kenya, and drilling operations continue on the Sabisa #1 well in the South Omo Block in Ethiopia. A result for Sabisa is expected in late May and Ngamia testing completed in early June.

Africa Oil CEO Keith Hill commented, "The Etuko prospect is one of the most attractive prospects in our portfolio and has the potential to open up an new play fairway on the eastern side of the already proven Lockichar Basin. A number of additional prospects and leads will be de-risked on this 'eastern flank' play if the Etuko well is successful. With three rigs active and three more on the way, the second half of 2013 promises to be a very exciting period in the continuing growth story of the Company in East Africa."
