Tullow Oil plc (Tullow) has 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 3083 m. The well was intended to establish a working petroleum system and test a structural closure in the south-western part of the basin. The strong oil shows encountered during the drilling of Cheptuket-1 are indicative of the presence of an active petroleum system with significant oil generation. Post-well analysis is in progress ahead of defining the future exploration programme in the basin. The PR Marriott Rig-46 will now be demobilised as previously recommended. Further to 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%.
Angus McCoss, Exploration Director, commented:
“This is the most significant well result to date in Kenya outside the South Lokichar basin. Encountering strong oil shows across such a large interval is very encouraging indeed. I am delighted by this wildcat well result and the team are already working on our follow-up exploration plans for the Kerio Valley Basin.”
