TransGlobe Energy Corporation Production Status Update

Mar 21, 2011 - 10 04 ET

CALGARY, ALBERTA--(Marketwire - March 21, 2011) - TransGlobe Energy Corporation (TSX:TGL) (NASDAQ:TGA) ("TransGlobe" or the "Company") announces production increases in the Arab Republic of Egypt ("Egypt") and curtailed production in the Republic of Yemen ("Yemen").

OPERATIONS UPDATE

ARAB REPUBLIC OF EGYPT

West Gharib, Arab Republic of Egypt (100% working interest, TransGlobe operated)

Operations

During the first quarter, six oil wells were drilled; two Upper Nukhul wells and four dual Nukhul (Upper and Lower) wells. In addition, two drilling rigs are currently drilling at West Gharib, primarily focused on the Nukhul formation. It is expected that up to 44 wells could be drilled in West Gharib during 2011, primarily focused on the Nukhul formation.

Production

During March, the Company has completed three Lower Nukhul and two Upper Nukhul oil wells. March production to-date has averaged approximately 9,100 barrels of oil per day ("Bopd") representing a 12% increase from February production of 8,133 Bopd. Daily production today has increased to approximately 11,500 Bopd with the addition of the third Lower Nukhul producer which represents a 3,367 Bopd increase or a 41% increase over February production.

The Arta / East Arta Lower Nukhul pool has expanded significantly since year-end 2010. The Company has now drilled six Lower Nukhul wells which have encountered a sandstone/conglomerate reservoir up to 130 feet thick. Five wells have been placed on production with initial production rates of over 1,000 Bopd per well without the requirement for fracture stimulation. These results are better than the modeled average of 500 Bopd for a Lower Nukhul producer. One additional well reached total depth on March 20 and is being cased as a dual Nukhul (Upper and Lower) oil well. This latest well has extended the reservoir an additional 90 feet down dip and did not encounter the oil / water contact.

Additionally, two Upper Nukhul oil wells in the north portion of the East Arta pool were frac'd this past week and are currently being equipped for production.

YEMEN WEST- Marib Basin

Block S-1, Republic of Yemen (25% working interest)

Production

The oil export pipeline from Marib to the Ras Eisa port on the Red Sea is currently shut down. Production from TransGlobe's An Nagyah field on Block S-1 is shut-in until repairs to the export pipeline can be completed. The pipeline was damaged by an explosion and a local tribal group is preventing repair crew access to the pipeline because of a dispute with the government. It is difficult to predict when production will resume. TransGlobe's working interest share of production was approximately 2,300 Bopd prior to being shut-in on March 17.

CORPORATE PRODUCTION

Corporate production today is approximately 12,000 Bopd, not including approximately 2,300 Bopd of shut-in production on Block S-1. Production from Block 32 in East Yemen of approximately 500 Bopd to TransGlobe has not been affected. Block 32 production is exported through the Nexen Inc. operated pipeline to the Indian Ocean.

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.
