Kazakh AKD06 Well Flows Over 4,300 Barrels of Oil Per Day

BOZOI, KAZAKHSTAN, Nov 15, 2011 (MARKETWIRE via COMTEX) --

Tethys Petroleum Limited ("Tethys" or the "Company") (TSX: TPL)(LSE: TPL) today announced that the Cretaceous sand interval on the AKD06 Doris appraisal well had tested oil at a rate of over 4,300 barrels of oil ("bopd") per day.

"This is a very successful appraisal of the Doris discovery and once again shows the good flow potential of the Cretaceous sandstone reservoir. This is an excellent result and bodes well for the further development of Doris," commented Graham Wall, Chief Operating Officer of Tethys.

A 5 metre interval (2,165 metres to 2,170 metres) of the Cretaceous sand flowed at a rate of 4,304 bopd on a 26 mm (66/64") choke with a flowing tubing head pressure of 12.7 atmospheres (186 psi). The oil was light with a gravity of 0.8 SG (45 degrees API). Flow was restricted for safety reasons but data indicates that the absolute open flow potential is in excess of 6,000 bopd. The well is now tied into the test production facilities and further testing is planned in addition to placing the well on long-term test production.

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.
