Tullow Oil Plc has announced that it has found 30 meters (100 feet) of oil at the Twiga South-1 exploration well as well as a layer of ‘tight oil’ that’s 796 meters deep, the company said in a statement in London. Tullow has said it is more confident that it will uncover oil and gas in neighboring areas of Kenya and Ethiopia.
Tullow, along with its partner Africa Oil Corp made the first oil discovery in Kenya earlier this year at Ngamia-1 well in Turkana. Tullow’s Chief Executive Officer Aidan Heavey said in May that Kenya, which has no history of oil production, may have more potential than neighboring Uganda, where the company and its partners have found about 2.5 billion barrels of resources.
The statement said that Twiga South-1 has been drilled to a total depth of 3,250 metres and has been successfully logged and sampled. Three sandstone reservoir zones, similar to Ngamia-1, were encountered and moveable oil has been recovered to surface.
According to reports, Tullow, along with its partner Africa Oil Corp. (AOI), will now conduct a series of flow tests at Twiga-1 over the next four to eight weeks. It will then move the rig back to its first discovery in Kenya at the Ngamia-1 well, where it found more than 100 meters of oil.
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 by Tullow and is the first oil discovery in Block 13T. It is located 22km to the north of the Ngamia-1A discovery.
Tullow has a 50% operated interest in the Twiga South-1 well with Africa Oil holding the remaining 50% interest.
