CALGARY, ALBERTA--(Marketwired - Aug. 28, 2013) - TransGlobe Energy Corporation (TSX:TGL) (NASDAQ:TGA) ("TransGlobe" or the "Company") is pleased to announce a successful Jurassic gas/condensate test in the Western Desert at North Dabaa 1X.

ARAB REPUBLIC OF EGYPT

East Ghazalat Block, Arab Republic of Egypt (50% working interest, non-operated)

The North Dabaa 1X exploration well was drilled to a total depth of 14,740 feet and cased as a Cretaceous oil and Jurassic gas condensate discovery. Based on open hole well logs and samples, the well encountered approximately 8 feet of net oil pay in the Abu Roash formation and 23 feet of net gas/condensate pay in the Khatatba formation.

The Khatatba formation (9,882-9,906 ft) was completed and flow tested using the drilling rig for a total duration of 72.5 hours. During this period, approximately 48.9 million cubic feet of gas ("MMcf") and 4,893 barrels ("Bbl") of 56.9° API condensate were recovered on choke sizes varying from 18/64 inch to 64/64 inch and corresponding wellhead drawdowns of 2% to 44%. This represents average rates during the entire flow test of 16.2 million cubic feet of gas per day ("MMcfd") and 1,620 barrels per day ("Bpd") of condensate. An extended flow period of 26 hours was performed on a 64/64 inch choke during the test resulting in rates of 26.0 MMcfd of gas and 2,571 Bpd of condensate. Shut-in periods were conducted during the test however a detailed well test analysis has not been performed. The test results should be considered as preliminary and are not necessarily indicative of long-term performance. The well was suspended and the drilling rig was released. The new pool discovery will require additional drilling to determine the extent and commerciality of the discovery.

The Abu Roash oil zone will be completed and production tested at a future date using a work over rig.

The North Dabaa 1X exploration well was drilled, cased, completed and tested for a total estimated cost of $6.6 million ($3.3 million to TransGlobe).

The North Dabaa 1X discovery is located approximately 1.4 kilometers east of the Company's newly awarded 100% working interest South Ghazalat concession which is awaiting Government ratification.
