News Release

East Africa operational update

24 June 2014 - Africa Oil, Tullow Oil's partner in Blocks 10BB and 13T in Northern Kenya (Tullow 50% operated interest), today issued the following operational update. 

Ngamia-2 appraisal well encounters up to 39 metres of net oil pay and 11 metres of net gas pay

"The PR Marriott 46 rig has recently completed the Ngamia-2 well which was drilled 1.7 km from the Ngamia-1 discovery well to test the northwest flank of the prospect.  The well encountered up to 39 meters of net oil pay and 11 meters of net gas pay and appears to have identified a new fault block trap north of the main Ngamia accumulation.  The reservoirs were high quality with more than 200 meters of net reservoir sands with good permeability inferred from MDT sampling.  The well has been suspended for testing and the rig will continue to drill up to 4 additional appraisal wells in the Ngamia field area for an extended well test program.  A 3D seismic program is currently being concluded over the field area which should allow for detailed mapping of the fault trends."

Agete-1 well test flows at 500 bopd              

"The SMP-5 rig has completed testing operations on the Agete-1 well where it confirmed the Auwerwer pay previously released, the well flow rate was tested at 500 barrels of oil per day.  This rig is now currently on location at the Ewoi-1 discovery and is preparing to test, after which it will continue to be used to test discovery and appraisal wells in this basin." 

Additional drilling and testing operations in Kenya and Ethiopia

"The Weatherford 804 rig is currently drilling the Agete-2 downdip appraisal well and will then move to drill the Etom prospect which is 7 km north of the Agete discovery along the basin bounding 'string of pearls' trend.

The Sakson PR-5 rig is drilling the Amosing-2 downdip appraisal well, with a planned sidetrack, and will then move to test the North Kerio and Turkana Central Basins by drilling the Kodos and Epir (formerly Aze) prospects respectively.

Finally, the Exalo 205 rig is drilling ahead on the Gardim prospect, located in the Chew Bahir basin in the South Omo block in Ethiopia.  The partnership is in discussions on the next prospect to be considered for drilling in this block."

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

"The success of the Ngamia-2 exploratory appraisal well builds on our major basin opening discovery well, Ngamia-1. The reservoirs were of similar quality and the well will be suspended for testing. The Agete -1 well test flowed at 500 bopd and the partnership continue to evaluate this discovery. With five rigs drilling in Kenya and Ethiopia, there is much to look forward to in the second half of the year."
