Tullow Oil encounters good oil shows in Northern Kenya well 

Tullow Oil announced that the Cheptuket-1 well in Block 12A, Northern Kenya, has encountered good oil shows, seen in cuttings and rotary sidewall cores, across an interval of over 700 m. Cheptuket-1 is the first well to test the Kerio Valley Basin and was drilled by the PR Marriott Rig-46 to a final depth of 3,083 m.

The objective of the well was to establish a working petroleum system and test a structural closure in the south western part of the basin. The strong oil shows encountered in Cheptuket-1 indicate the presence of an active petroleum system with significant oil generation. Post well analysis is in progress ahead of defining the future exploration program in the basin. As previously advised, the PR Marriott Rig-46 will now be demobilized. On the back of the encouraging Cheptuket-1 and successful Etom-2 results further exploration activities are being evaluated.

Tullow operates Block 12A with 40% equity and is partnered by Delonex Energy with 40% and Africa Oil Corporation with 20%.
