17 March 2016, Nairobi — Tullow Oil plc announced Wednesday that the Cheptuket-1 well in Block 12A, Northern Kenya, has encountered “good” oil shows across an interval of almost 2,300 feet.
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 10,114 feet. 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 the well indicate the presence of an active petroleum system with significant oil generation, according to a Tullow statement.
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 demobilised. On the back of the successful Cheptuket-1 and Etom-2 well results further exploration activities are being evaluated by the company.
Tullow Exploration Director Angus McCoss said in a company statement:
“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.”
Tullow operates Block 12A with 40 percent equity and is partnered by Delonex Energy, which also holds a 40 percent interest, and Africa Oil Corporation, which holds a 20 percent interest.
