Twiga South-1 drilling update

Drilling is on-going and, as previously stated by partners Africa Oil Corp (Africa Oil) on October 26 2012, an announcement of the drilling result is expected in early to mid-November after target depth has been achieved and necessary sampling and analysis has been completed.

The Twiga South-1 structure is the second prospect to be tested as part of a multi-well drilling campaign in Kenya and Ethiopia and is the first discovery in block 13T following the Ngamia-1 discovery earlier this year in Block 10BB.

Tullow has a 50% operated interest in the Twiga South-1 well with Africa Oil holding the remaining 50% interest.
