Tullow Oil plc has announced that the Twiga South-1 exploration well in Block 13T, onshore Kenya, has encountered 30 meters of net oil pay. The well has also encountered a tight fractured rock section with hydrocarbon shows over a gross interval of 796 meters.
Three sandstone reservoir zones were encountered and moveable oil, with an API greater than 30 degrees, has been recovered to surface.
In addition to the net pay, the well also penetrated a thick section of tight fractured rock below 2,272 meters which had extensive hydrocarbon shows over a gross interval of 796 meters. Moveable oil with an API greater than 30 degrees was also successfully sampled from this section.
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 22 kilometers to the north of the Ngamia-1A discovery and further de-risks a number of other similar features on the western margin of the basin.

“Following the basin-opening Ngamia-1 well result earlier this year, I am pleased to announce that our second well in our onshore Kenya rift basins campaign has also discovered oil,” said Exploration Director, Angus McCoss. “This immediate follow on discovery reaffirms the considerable prospectivity of the Lokichar Basin. Having significantly expanded our plans in Kenya and Ethiopia, there is much to look forward to as the exploration campaign and testing program move ahead.”
