LONDON--Tullow Oil PLC (TLW.LN) Thursday said drilling at three wells in Kenya have found oil.

The oil explorer reported successful results from testing at onshore blocks 10BB and 13T, which it operates and has a 50% equity stake in. Africa Oil Corp (AOI.T) owes the other half.

"Etom-1 has successfully extended the South Lokichar rift bounding fault play northwards and we look forward to testing the southern area of the basin with Ekosowan-1," said Tullow's Exploration Director Angus McCoss. "Continued success in appraisal of the Ngamia and Amosing fields reinforces our belief that the South Lokichar basin holds very considerable potential which we hope to replicate in additional basins."
