Tethys to Test Production at Persea 1 Well

Tethys Petroleum Limited 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.
