Exploration firm Tullow oil is set to announce whether it has good prospects of finding oil in Twiga South-1 exploration well in Turkana county.
A statement posted on its website says the drilling activities will have reached the total depth 3,114 metres in a matter of weeks and pave way for testing.
Tullow announced in late October that oil had been encountered in the Twiga South-1 well but that further details would be released after a full set of sample tests have been run after achieving the target depth.
Drilling at Paipai-1 well commenced Block 10A is also ongoing with a target depth of 4,500 metres. Tullow Kenya general manager Martin Mbogo said the appraisal testing for Ngamia1 prospect where they found 100 metres of oil net pay will be conducted early next year.
