Azerbaijan, Baku, Oct 12 / Trend E. Kosolapova/
Central Asian Oil and Gas Company Tethys Petroleum Limited announced the preliminary results of exploration well AKD07 drilled in the Akkulka Block in Kazakhstan, the company said on Friday.
"The initial drilling and electric log results show potential hydrocarbons in the Jurassic limestone sequence and lower down in a thin Jurassic sandstone near the current total depth of the well," the company said.
According to the company, The "Dyna" sheet sand and the "Doris" channel sand were both present and of good quality but both have been interpreted as being water bearing.
The current total depth is 2,585 metres in the Upper Jurassic sequence with a thin potentially oil bearing sand having been encountered just above total depth. The Upper Jurassic limestone interval some 1.75 km and 1.8 km away respectively has a gross thickness of some 22 metres. Drilling and wireline log data indicate moveable hydrocarbons within this zone.
Further analysis of the log data on the Jurassic limestone is currently underway and drilling is about to recommence to a new planned total depth of 2,750 metres in order to fully assess the potential of the Upper Jurassic sand interval. At this point a decision will be made on running casing and testing the well. It is expected that the new TD will be reached within the next week.
Tethys Petroleum Limited is an oil and gas exploration and production company currently focusing on Central Asia with projects in oil-rich Kazakhstan, Tajikistan and Uzbekistan. It is the only independent oil and gas company operating in all three countries.
