Block 12A joint venture partners Tullow Oil and Africa Oil have announced they will spud the Cheptuket exploration well in October to test a basin bounding structural closure in the Kerio Valley Basin in a similar structural setting to the successful Ngamia and Amosing discoveries.
The Cheptuket well formerly refered to as Lekep-A is located in Elgeyo Marakwet county in Kenya’s Rift Valley where the oil firms had already conducted an environment and social impact assessment exercise (ESIA) in readiness for the drilling.
The two partners have conducted seismic surveys and identified a number of leads on the block including the proposed Lekep-A well with results as well as data collected from this exploration well are expected to provide further information for future drilling programs
Other wells under consideration include Etom North an appraisal well to follow up on our success at Etom-1 and Tausi a basin opening well.
Meanwhile preparations are now well advanced for the Ngamia field EWTs which are due to commence in August. In preparation for the Ngamia EWTs, multi zone completions have been installed in the Ngamia-8, Ngamia-3 and Ngamia-6 wells and clean-up flow testing has been completed.
The Ngamia EWT flow test will be followed by water injection testing. Elsewhere in the South Lokichar basin, Ngamia-9, an appraisal well for this field, was completed in July 2015 and encountered between 90 metres and 110 metres of net oil pay in the Lokone and Auwerwer horizons.
A one rig operation continues with the drilling of the Twiga-3 well, which is currently underway, followed by the large Amosing North prospect (Amosing-5) located on the northern flank of Amosing and updip of the Ngamia field (that was identified from the 3D seismic).
In parallel with the exploration and appraisal program, pre-FEED (Front End Engineering and Design) studies are being progressed for entry in to FEED.
