Tethys Petroleum Limited: Uzbekistan MOU Signed 
 
TASHKENT, UZBEKISTAN--(Marketwire - Nov. 18, 2011) - Tethys Petroleum Limited ("Tethys" or the "Company") 
(TSX:TPL)(LSE:TPL) today announced it has signed a Memorandum of Understanding ("MOU") with the Uzbek State oil 
and gas company, National Holding Company "Uzbekneftegaz" ("UNG") establishing a programme for Tethys to obtain 
two new Production Enhancement Contracts ("PECs") on two existing oilfields in Uzbekistan. 
 
The MOU represents an agreed timetable up to May 1, 2012 to negotiate for two new PECs one for the Chegara 
Group of fields and one on the West Kruk field. The PECs are expected to be a similar contractual arrangement 
to the PEC that Tethys has over the North Urtabulak Field in Uzbekistan that has operated successfully for some 
10 years. The Chegara and West Kruk fields are located in the same area as North Urtabulak. Under this contract 
Tethys is allocated refined products for the oil it produces and sells these on the export market in United 
States dollars. The Chegara Group of fields is less 
developed than North Urtabulak and Tethys believes that these fields give significant potential for additional 
oil production in the short term. 
 
Mamuka Murjikneli, Regional Manager, commented, "This MOU is an excellent step forward with our partners 
Uzbekneftegaz to work on more oil fields in Uzbekistan. Given the experience and expertise Tethys has in 
Uzbekistan and the region this offers a real opportunity to add to Tethys' existing portfolio of high impact 
projects. These additional fields can be developed in conjunction with our currently producing North Urtabulak 
oil field increasing our short to medium term oil production base and cash flow in Uzbekistan." 
 
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.
