AKD08 (Doto) Well
The AKD08 (Doto) well has reached a depth of 1,368 metres and electric logs have been run in the hole. The 13 3/8th casing is being run and once cemented drilling will recommence in the 12 1/4" hole section. The Doto well is expected to take approximately 70 days in total to drill to a planned total depth of 3,500 metres using Tethys' own ZJ70 "Telesto" rig. The well is located to the south-west of the Company's producing Doris field and north of its Dione oil discovery in Kazakhstan. The well is designed to target several potential zones, including the Lower Cretaceous sandstone and Upper Jurassic carbonate sequences as proven in Doris, and also the deeper Triassic sequence.
Whilst drilling in the shallower levels at approximately 600 metres, high levels of gas were encountered and these shows together with the logs indicate a potential gas discovery at the Tasaran stratigraphic level as previously demonstrated to be commercial on test in the nearby AKK14 and AKK15 wells. It is expected that a gas appraisal well could now be incorporated into the forward shallow gas drilling program to test this accumulation.
