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 metres.
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 programme in the basin. As previously advised, the PR Marriott Rig-46 will now be demobilised. 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%.
ANGUS MCCOSS, EXPLORATION DIRECTOR, COMMENTED TODAY:
“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.”
