TransGlobe Energy Corporation Announces Well Results at Narmer #1, Nuqra Block 1, Egypt

May 11, 2007 - 04 38 ET

CALGARY, ALBERTA--(CCNMatthews - May 11, 2007) - TransGlobe Energy Corporation ("TransGlobe" or the "Company") (TSX:TGL) (AMEX:TGA) announces well results at Narmer #1.

Nuqra Block 1, Arab Republic of Egypt (50% working interest)

The Narmer #1 exploration well was drilled to a total measured depth of 2,701 meters (8,860 feet) and subsequently plugged and abandoned. Strong hydrocarbon shows were encountered in the Cretaceous sands from 380 to 840 meters (1,250 to 2,750 feet) however the log analysis indicated the reservoir sands were water-bearing. No hydrocarbon shows were encountered in the Jurassic sands. Narmer #1 was targeting Jurassic sands and was not optimally located for a Cretaceous target. The hydrocarbon shows and well logs indicate the presence of a 460 meter (1,500 foot) interval of mature source rocks in the Cretaceous section of the Nuqra basin. The identification of mature source rocks, at this shallow depth, reduces the risk and the cost of future exploration drilling. Narmer #1 has confirmed that hydrocarbons are being generated in this under-explored basin. The seismic data will be remapped to attempt to identify Cretaceous targets for a possible future drilling program.

The contingent well proposed for West Narmer #1 will not be drilled as it was targeting a Jurassic prospect similar to the Narmer #1 well. The drilling rig was released on May 11 to the operator of the adjacent exploration block located west of the Nile. The Narmer #1 well was the second of a two-well commitment targeting Cretaceous and Jurassic prospects in the Nuqra/Kom Ombo rift basin located near Aswan, Egypt. The current exploration period expires on July 17, 2009 and may be extended to July 17, 2012 with an exploration commitment of two wells.
