TGL TransGlobe Energy Corporation

TransGlobe Energy Corporation (TSX: TGL) (NASDAQ: TGA) ("TransGlobe" or the "Company") today announced its 2009 year-end reserves. All dollar values are expressed in United States dollars unless otherwise stated.

The Company's 2009 and 2008 year-end reserves were prepared by the independent reserves evaluation firm of DeGolyer and MacNaughton Canada Limited ("DeGolyer"), in accordance with National Instrument 51-101. Following is a summary of DeGolyer's evaluation for the year ended December 31, 2009 with comparatives to the year ended December 31, 2008.

The recovery and reserve estimates of crude oil, natural gas liquids ("NGLs") and natural gas reserves provided in this news release are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual crude oil, NGL and natural gas reserves may be greater than, or less than, the estimates provided herein. All reserves presented are based on DeGolyer's forecast pricing effective December 31, 2009 and December 31, 2008, respectively.

Year-End 2009 Reserves(i)

Proved Reserves ("1P")

TransGlobe's total proved reserves increased 53 percent from 12.6 million barrels of oil ("MMbbl") at December 31, 2008 to 19.2 MMbbl at December 31, 2009. This increase in proved reserves represents a production replacement in 2009 of 303 percent.

Proved Plus Probable Reserves ("2P")

Total 2P reserves grew 22 percent from 19.8 MMbbl at December 31, 2008 to 24.2 MMbbl at December 31, 2009. The increase in 2P reserves represents a production replacement in 2009 of 234 percent.

Proved Plus Probable Plus Possible Reserves ("3P")

Total 3P reserves grew 9 percent from 28.0 MMbbl at December 31, 2008 to 30.5 MMbbl at December 31, 2009. The increase in 3P reserves represents a production replacement in 2009 of 176 percent.

(i) Definitions of Reserves Categories:

- Proved reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

- Probable reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves.

- Possible reserves have a less likely chance of being recovered than probable reserves. This term is often used for reserves which are claimed to have at least a 10 percent certainty of being produced.

2009 Significant Events

In 2009, the Company's activities focused primarily on the development of its operated West Gharib concession in the Arab Republic of Egypt ("Egypt").

In Egypt, the Company's 1P reserves grew 125 percent over 2008, representing a production replacement of 440 percent. On 2P basis, the year-over-year increase was 40 percent, equal to a production replacement of 324 percent. The most significant reserves additions during the year resulted from the appraisal/development drilling at Hana West and the recognition of reserves associated with enhanced recovery projects at the Hana, Hoshia and Hana West fields. Water injection was initiated in both the Hana and Hoshia fields during 2008 and in the Hana West field during 2009. Approximately 67 percent of the corporate 1P reserve additions and 62 percent of the corporate 2P reserve additions during 2009 were attributed to the water flood projects at Hana, Hoshia and Hana West.

In Yemen, 2009 production was partially replaced by improved recovery factors at the An Nagyah, Tasour and Godah fields. The Company's 1P reserves in Yemen decreased 9 percent over the prior year, representing a production replacement of 48 percent. On a 2P basis, reserves in Yemen decreased 5 percent over the prior year, representing a production replacement of 68 percent.

Estimated Future Net Revenues

All evaluations and reviews of future net cash flow are stated prior to any provision for interest costs or general and administrative costs and after the deduction of estimated future capital expenditures for wells to which reserves have been assigned. It should not be assumed that the estimated future net cash flow shown below is representative of the fair market value of the Company's properties. There is no assurance that such price and cost assumptions will be attained, and variances could be material. The recovery and reserve estimates of crude oil, NGL and natural gas reserves provided herein are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual crude oil, NGL and natural gas reserves may be greater than or less than the estimates provided herein.

The estimated future net revenues for year ended 2009 presented below in millions of U.S. dollars ("$MM") are calculated using DeGolyer's price forecast at December 31, 2009 and constant pricing using the Securities and Exchange Commissions' ("SEC") average price (the 12 month average price using in the first day of the month prices during 2009).

The estimated future net revenues for year ended 2008 presented below in millions of U.S. dollars are calculated using DeGolyer's price forecast at December 31, 2008 and constant pricing using the average price received on December 31, 2008.

In the constant price cases, the prices were held constant for the life of the reserves.

The constant pricing used to estimate future net revenues is as follows, with Egypt prices based on prices received for West Gharib production and Yemen prices based on prices received for production from Blocks 32 and S-1.

Pursuant to the SEC pronouncement in 2009, the Constant price case for 2009 is based on the average of the reference price received on the first of each month during 2009 adjusted for respective differentials at year ended 2009. Prior to 2009, the 2008 constant price cases were run using the December 31, 2008 pricing.
