Tullow Oil plc (Tullow) is pleased to announce that the Ekales-1 wildcat, located in Block 13T in Northern Kenya, has made a new oil discovery. Results of drilling, wireline logs and samples of reservoir fluid indicate a potential net oil pay in the Auwerwer and Upper Lokone sandstone reservoirs of between 60 and 100 metres. Future flow testing aims to confirm productivity from these zones.

This is the fourth consecutive wildcat discovery, in the first oil basin opened in Northern Kenya, since our drilling commenced in 2012. The Ekales-1 well is located between the Ngamia-1 and Twiga South-1 oil discoveries and the reservoir properties at this location appear similar to those previously encountered. Once operations have completed the rig will move to drill the exploration prospect Amosing-1 south of Ngamia-1.

Tullow operates the Ekales-1 well and Africa Oil (50%) has a non-operated interest.
