Tullow Oil' s Kenya Twiga South-1 well encounters 30 m of net oil pay

LONDON -- Tullow Oil said the Twiga South-1 exploration well in Block 13T, onshore Kenya, has encountered 30 m of net oil pay with further potential to be assessed on test. Well has also encountered a tight fractured rock section with hydrocarbon shows over a gross interval of 796 m. Twiga South 1 has been drilled to a total depth of 3,250 m and has been successfully logged and sampled.

Three sandstone reservoir zones, analogous to Ngamia 1, were encountered and moveable oil, with an API greater than 30 degrees, has been recovered to surface. Further potential exists up dip of the well and will be subsequently appraised. Well also penetrated a thick section of tight fractured rock below 2,272 m which had extensive hydrocarbon shows over a gross interval of 796 m.

A series of flow tests will now be conducted on the well over the next four to eight weeks. Following completion of the testing program, the rig will move back to flow test the Ngamia 1 well.Tullow has a 50% operated interest in the Twiga South 1 well with Africa Oil the remaining 50% interest.

Paipai 1 well in Block 10A in Kenya is expected by the end of the year and the Sabisa 1 well in the South Omo Block in Ethiopia is expected to start drilling by the end of December.
