Africa Oil announces Kenyan oil discovery
VANCOUVER, B.C. -- Africa Oil Corp. has announced the second significant oil discovery in Kenya at the Twiga South-1 well. The Twiga South-1 exploration well, located in Block 13T, onshore Kenya, has encountered 30 m of net oil pay in Tertiary sandstone reservoirs with further potential to be assessed by testing. In addition, the well has also encountered a thick sequence of fractured rock section exhibiting oil and wet gas shows over a gross interval of 796 m.
Twiga South-1 has been drilled to a total depth of 3,250 m and has been successfully logged and sampled. Three sandstone reservoir units, analogous to Ngamia-1, were encountered and moveable oil, with an API gravity greater than 30°, has been recovered to surface from all three zones. Further potential exists up dip of the well and will be subsequently appraised.
In addition to the net pay in shallower reservoirs, the well also penetrated a thick section of lower porosity fractured rocks below 2,272 m that had extensive hydrocarbon shows over a gross interval of 796 m. Moveable oil with an API gravity greater than 30° was also successfully sampled from this section. This fractured rock section is a new play-type for the region that will be further evaluated by testing to understand its extent and any productive potential.
The Twiga South structure is the second prospect to be tested in the Lokichar Basin as part of a multi-well drilling campaign in Kenya and Ethiopia and is the first oil discovery in Block 13T. It is located over 22 km to the north of the Ngamia-1 discovery and further de-risks a number of other similar features on the western margin of the basin.
A series of flow tests will now be conducted on the well over the next 4–8 weeks. Following completion of the testing program, the rig will move back to flow test the Ngamia-1 well.
Elsewhere in Africa Oil' s East African Rift basin portfolio, the Paipai-1 well in Block 10A in Kenya is drilling as planned and results are expected to be released by the end of the year. Mobilization of the drilling rig for the Sabisa-1 well in the South Omo Block in Ethiopia is proceeding and the well is expected to commence drilling by the end of December.
Keith Hill, President and CEO of Africa Oil commented, "This second discovery, immediately following the basin-opening Ngamia-1 well result earlier this year, reaffirms the considerable prospectivity of the Lokichar Basin. Of notable interest, is the new fractured play opportunity which has been encountered for the first time in East Africa. We are very pleased with these exciting results to date and have significantly expanded our plans in Kenya and Ethiopia. With over 100 significant prospects and leads identified and an active drilling program with at least 3 drilling rigs operational, there is much to look forward to in 2013 as the exploration campaign and testing program move ahead."
The Twiga South-1 well is operated by Tullow Oil plc who hold a 50% working interest. Africa Oil holds the remaining 50% interest.
