Tethys Petroleum Limited: Tajikistan Persea 1 Well Initial Results 
 
DUSHANBE, TAJIKISTAN--(Marketwire - Dec. 19, 2011) - Tethys Petroleum Limited ("Tethys" or the "Company") 
(TSX:TPL)(LSE:TPL) today announced the initial results of its Persea 1 exploration well in Tajikistan and its 
intention to carry out production testing on the well in the new year. 
 
The Persea 1 well, drilled some 5 kilometres from the town of Kurgan Teppa, reached a total depth of 2,655 
metres. Wireline logs show a 50 metre gross zone of possible hydrocarbons within a mixed sandstone and 
carbonate sequence assigned to the Alai formation, similar to that about to be tested in the East Olimtoi 
(EOL09 well). Because of hole stability issues the section was drilled with relatively high mudweights which 
tends to mask hydrocarbon shows whilst drilling. 
 
The Company now intends to run 7-inch liner in preparation for a production test with the aim of establishing 
commercial flow of hydrocarbons from this zone. The actual testing itself will be carried out in the first half 
of 2012 with the cost to be financed by internally generated cash flow. 
 
Following the recent acquisition of additional interest in the Bokhtar Production Sharing Contract, which 
includes the Persea prospect, Tethys now holds an 85% working interest in this prospect. 
 
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.
