Doris AKD06 Well Initial Results

BOZOI, KAZAKHSTAN, Sep 26, 2011 (MARKETWIRE via COMTEX) --

Tethys Petroleum Limited ("Tethys" or the "Company") (TSX: TPL)(LSE: TPL) today gave an update on the initial results of the AKD06 Doris appraisal well in Kazakhstan.

Drilling data and wireline logs indicate oil in both the Cretaceous sandstone and Jurassic limestone reservoirs. The Cretaceous sandstone has been encountered above prognosis and at a higher elevation than in the AKD01 Doris discovery well and is of good quality with similar net pay thickness to AKD01, which flowed over 5,400 barrels of oil per day from this unit. The Jurassic limestone has also been encountered above prognosis and slightly higher than in the AKD01 well and has similar character to the recently drilled AKD05 well which flowed over 1,500 barrels of oil per day from this zone. Further analysis of these initial data is currently underway.

Production liner has now been run and cemented and this will be followed by the gathering of additional geophysical data to tie this well into the new 3D seismic dataset. The well will then be tied into the test production facility and two production tests are planned on the reservoir units. Testing will commence as soon as is practical, expected to be within the next month.

Tethys is focused on oil and gas exploration and production activities in Central Asia with activities currently in the Republics of Tajikistan, Kazakhstan 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.
