TransGlobe Energy Corporation Announces Successful Appraisal Well in Republic of Yemen

Jul 14, 2004 - 10 06 ET

CALGARY, ALBERTA--(CCNMatthews - Jul 14, 2004) - TransGlobe 
Energy Corporation ("TransGlobe" or the "Company") is pleased to 
announce another successful development well on Block S-1 in the 
Republic of Yemen.  

BLOCK S-1, REPUBLIC OF YEMEN (25% WORKING INTEREST)  

Successful Appraisal at An Nagyah #8:  

The An Nagyah #8 well was drilled to a total depth of 1,209 
meters and suspended as a potential oil well after flowing at a 
stabilised rate of 607 barrels of light (43 degree API) oil per 
day. The An Nagyah #8 well encountered the Upper Lam sandstones 
with a 13 meter oil bearing interval. A 10.5 meter reservoir 
interval in the oil bearing section was perforated between 
1,019.5 and 1,030 meters. 

The An Nagyah #8 well has defined the eastern limit of the An 
Nagyah structure. An Nagyah #8 is located 2.3 kilometers east of 
the An Nagyah #6 well which tested light sweet oil at 1,140 Bopd 
from a 29 meter perforated interval (April 28, 2004 
announcement). The well is being equipped for early production 
via trucking. The drilling rig is currently moving to An Nagyah 
#9 which is located between the An Nagyah #4 and An Nagyah #6 
wells.  

An Nagyah Production Update: 

The early production facilities at the An Nagyah field were 
installed during the first quarter and field production 
operations were initiated on March 30, 2004. The average 
production during June 2004 was 3,288 Bopd (821 Bopd to 
TransGlobe) with the addition of An Nagyah #7 in mid June. The An 
Nagyah #7 well was drilled to define the western limit of the An 
Nagyah structure (May 26, 2004 announcement) and has stabilized 
at approximately 360 Bopd since being placed on production. The 
oil production is currently being trucked 18 miles to the Jannah 
Hunt facility where it enters the Hunt pipeline system to the Red 
Sea. 

The trucking operations will be phased out following the 
construction of a central production facility ("CPF") at An 
Nagyah and a 28 kilometer (18 mile) pipeline to the Jannah Hunt 
export pipeline. The pipeline and facilities are expected to be 
operational by early 2005. The 10 inch pipeline is designed to 
allow an ultimate capacity of 80,000 Bopd so that future 
discoveries can be placed on stream quickly. The CPF is designed 
for an initial capacity of 10,000 Bopd (2,500 Bopd to 
TransGlobe), with expansion capabilities. Additional development 
wells in the An Nagyah pool are expected to be drilled in the 
third and fourth quarters of 2004 and into 2005. 

TransGlobe is an international exploration and production company 
with its corporate office in Calgary, Alberta. In addition to its 
25% interest in Block S-1, the Company holds a 33% working 
interest in Block 72 and a 13.81% working interest in Block 32 in 
the Republic of Yemen. Block 72 is a new exploration area for 
TransGlobe where exploration operations are expected to commence 
in 2005. The Tasour field in Block 32 was developed and placed on 
production in 2000 and is currently producing in excess of 20,000 
Bopd (approximately 2,750 Bopd to TransGlobe), having produced in 
excess of 17 millions barrels to date. TransGlobe also has 
producing oil and gas properties in Alberta, Canada.
