AKD07 to be Tested

Oct 18, 2012 (Marketwire via COMTEX) --Tethys Petroleum Limited (TSX:TPL)(LSE:TPL) today announced that it had reached a Total Depth ("TD") of 2,750 metres on the AKD07 exploration/appraisal well and has now run the production liner in order to test the Jurassic carbonate zone which appears to be oil bearing from the drilling and wireline log results.

The results of the TD logging confirm those of the previous wireline logging indicating potential oil in the Jurassic carbonate some 30 metres deeper than the previous lowest known oil encountered in the area. This interval is now to be production tested using a staged approach. A positive test could result in a significant upgrade in reserves in this zone in the Doris oil field area and provide further appraisal/development targets at this level.

In the remainder of the well down to TD, there were a number of sands encountered with limited hydrocarbon indications. However, these zones are likely too thin to contribute commercial production and, as such, will not be tested. It is expected that the initial test results for the Jurassic carbonate zone will be available within the next month.

The well was drilled and completed significantly quicker than originally projected.

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