Tethys announces commencement of drilling operations in Kazakhstan

Tethys is focused on oil and gas exploration and production activities in Central Asia with activities currently in Kazakhstan, Tajikistan and Uzbekistan. This highly prolific oil and gas area is rapidly developing and Tethys believes that significant potential exists in both exploration and in discovered deposits.

Almaty. September 14. Kazakhstan Today - Tethys Petroleum Limited announced on Wednesday the commencement of drilling operations at the AKD07 appraisal/exploration well in Kazakhstan, the company said.

The well is located to the south-east of the producing Doris field and is designed to target a potential down dip field extension at the Cretaceous Aptian sand level in what is believed to be a channel sand system (the 'Doris' sand), whilst simultaneously targeting an exciting exploration prospect (named 'Dyna'), which has been identified on the 3D seismic data from a bright amplitude anomaly at a slightly shallower level, and is interpreted to be part of a separate, larger sand fan or sheet sand system.

This Dyna prospect has 128 million barrels gross mean unrisked recoverable prospective resources attributed to it (Gustavson Associates). The well also has a deeper Jurassic level target as interpreted from the 3D seismic.

The well is forecast to take approximately 55 days to drill to a planned total depth of 2,540 meters using Tethys' own ZJ70 'Telesto' rig. Following the drilling it is planned to run wireline logs, and, subject to the log results, conduct flow testing operations.

The recently updated prospective resource report for Tethys' Kazakhstan assets (Gustavson Associates) estimates gross unrisked recoverable mean prospective oil resources of 1.23 billion barrels of oil and this is the first well since that report to target this exploration upside.
