TransGlobe Energy Corporation Tests Oil in Western Desert of Egypt

Jun 01, 2010 - 06 04 ET

CALGARY, ALBERTA--(Marketwire - June 1, 2010) - TransGlobe Energy Corporation ("TransGlobe" or the "Company") (TSX:TGL) (NASDAQ:TGA) announces a new oil discovery in the Western Desert of the Arab Republic of Egypt ("Egypt").

EGYPT

East Ghazalat (50% Working Interest)

TransGlobe is pleased to announce that oil was recovered on test from Safwa NW-1, its latest exploration well in the East Ghazalat Concession in the Western Desert of Egypt. Wire line logs across the Lower Bahariya Formation confirmed approximately 30 feet of net, producible oil-bearing reservoir with an average porosity exceeding 20%. A 14 foot interval was perforated and tested at a rate of 250 barrels of light, 34º API oil per day. The well is currently suspended awaiting a full test.

The Safwa NW-1 well is located 2.5 kilometers to the northwest of the Safwa #1 discovery well which tested 300 barrels of oil per day from the same formation. Safwa NW-1 was the fourth well and the second discovery in the exploration drilling program conducted by operator Vegas Oil & Gas SA ("Vegas") in partnership with TransGlobe. A fifth well located approximately 1.7 kilometers northeast of Safwa NW-1 is expected to spud in June to further appraise the Safwa structure. Fracture stimulation to increase oil production rates from the Bahariya Formation is also being investigated.

Mr. Ross Clarkson, President and CEO, was quoted "TransGlobe's entry into the prolific Western Desert in the East Ghazalat Concession is an exciting addition to our 2010 exploration program. The appraisal drilling at Safwa NW-1 is confirming the structural closure identified on the 3-D seismic mapping. We are encouraged that, with additional testing of the reservoir and continued drilling success, we may move to a commercial development in 2011."

The 858 km2 East Ghazalat Concession is located in the prolific Abu Gharadiq basin of Egypt's Western Desert, approximately 250 kilometers west of Cairo. East Ghazalat was awarded to Vegas on June 5, 2007 and is currently in the first, three-year exploration period which ends in early June 2010. There are two additional exploration period extensions of two years each. Subject to approval of the Egyptian Government, 25% of the original concession will be relinquished prior to entering the respective extension periods. All work commitments for the first, three-year exploration period have been met.

TransGlobe Energy Corporation is a Calgary-based, growth-oriented oil and gas exploration and development company focused on the Middle East/North Africa region with production operations in the Arab Republic of Egypt and the Republic of Yemen. TransGlobe's common shares trade on the Toronto Stock Exchange under the symbol TGL and on the NASDAQ Exchange under the symbol TGA.
