             CALGARY, ALBERTA--(Marketwire - Jan 23, 2013) -  TransGlobe Energy Corporation ("TransGlobe" or the "Company") (  TGL.TO) (  TGA) today announced its 2012 year-end reserves. All dollar values are expressed in United States dollars unless otherwise stated. 
            The Company's 2012 and 2011 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. 
           RESERVES
           The following  is a summary of DeGolyer's evaluation for the  year ended December 31,  2012 with comparatives to the year ended  December 31, 2011. 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, 2012 and December 31, 2011,  respectively. 
           Year-End 2012 Reserves*
           Proved Reserves ("1P")
            TransGlobe's total proved reserves increased 16 percent to   32.8 MMBbl at December 31, 2012 from 28.2 MMBbl at December 31,  2011.  This increase in proved reserves represents a production  replacement in  2012 of 172 percent. The Company produced 6.4 MMBbl of  reserves during  2012.
           Proved Plus Probable Reserves ("2P") 
            Total 2P reserves grew 10 percent to 48.7 MMBbl at December   31, 2012 from 44.2 MMBbl at December 31, 2011. The increase in 2P   reserves represents a production replacement in 2012 of 170 percent.
           Proved Plus Probable Plus Possible Reserves ("3P") 
            Total 3P reserves grew 4 percent to 62.4 MMBbl at December  31,  2012 from 59.8 MMBbl at December 31, 2011. The increase in 3P  reserves  represents a production replacement in 2012 of 141 percent.
           * 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.     Year-End Reserves Summary* |

            In 2012, the Company's activities focused primarily on the   continued development of its operated West Gharib and West Bakr   (acquired at the end of 2011) concessions in the Arab Republic of Egypt   ("Egypt").
           In Egypt, the Company's 1P reserves grew 22  percent over  2011, representing a production replacement of 189  percent. On a 2P  basis, the year-over-year increase was 14 percent,  equal to a production  replacement of 189 percent, while on a 3P basis,  the year-over-year  increase was 7 percent, equal to a production  replacement of 158  percent. 
           At West Gharib, the most  significant reserve additions during  the year were attributed to the  water flood performance and  development/appraisal drilling in the Lower  Nukhul Pool at Arta/East  Arta. Positive reserve additions to a lesser  extent were also attributed  to development/appraisal drilling at  Arta/East Arta in the Upper  Nukhul.
           At West Bakr, the  most significant reserve additions during  the year were attributed to  development appraisal drilling in the K and H  fields and improved water  flood performance in the H field.
           In the Republic of  Yemen ("Yemen"), reserves were reduced  primarily due to a curtailment  of future drilling activities in Block  S-1 due to political  instability. The reserves associated with the  Osaylan pool (1P of 0.4  MMBbl, 2P & 3P of 0.6 MMBbl at year end  2011) were reclassified as  Contingent Resources at year end 2012. The  Company's Yemen 1P, 2P and  3P reserves were decreased by 22%, 16% and  14% respectively from the  2011 year-end numbers.
           Estimated Future Net Revenues
            All evaluations and reviews of future net cash flows 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 years ended 2012 and   2011 presented below in millions of U.S. dollars ("$MM"), are calculated   using DeGolyer's price forecast at December 31, 2012 and December 31,   2011, respectively, and constant pricing using the Securities and   Exchange Commissions' ("SEC") average price (the 12-month average price   using the first day of the month prices during 2012 and 2011,   respectively). In the constant price cases, the prices were held   constant for the life of the reserves.

           This news release may include  certain statements that may  be deemed to be "forward-looking  statements" within the meaning of the  U.S. Private Securities  Litigation Reform Act of 1995. Such statements  relate to possible  future events. All statements other than statements  of historical fact  may be forward-looking statements. Forward-looking  statements are  often, but not always, identified by the use of words  such as "seek",  "anticipate", "plan", "continue", "estimate", "expect",  "may", "will",  "project", "predict", "potential", "targeting", "intend",  "could",  "might", "should", "believe" and similar expressions.  Statements  relating to "resources" are forward-looking statements as  they involve  the implied assessment, based on estimates and assumptions  that the  resources described exist in the quantities predicted or  estimated.  These statements involve known and unknown risks,  uncertainties and  other factors that may cause actual results or events  to differ  materially from those anticipated in such forward-looking  statements.  Although TransGlobe's forward-looking statements are based  on the  beliefs, expectations, opinions and assumptions of the Company's   management on the date the statements are made, such statements are   inherently uncertain and provide no guarantee of future  performance.  Actual results may differ materially from TransGlobe's  expectations as  reflected in such forward-looking statements as a result  of various  factors, many of which are beyond the control of the  Company. These  factors include, but are not limited to, unforeseen  changes in the rate  of production from TransGlobe's oil and gas  properties, changes in  price of crude oil and natural gas, adverse  technical factors  associated with exploration, development, production  or transportation  of TransGlobe's crude oil and natural gas reserves,  changes or  disruptions in the political or fiscal regimes in  TransGlobe's areas of  activity, changes in tax, energy or other laws or  regulations, changes  in significant capital expenditures, delays or  disruptions in  production due to shortages of skilled manpower,  equipment or  materials, economic fluctuations, upon completion of the  primary term  of any current exploration and/or production license,  TransGlobe would  secure an extension or additional license for any  accumulation or  discovered prospect; that TransGlobe intends to proceed  with  development and operation of any commercially viable discovered   prospect, and other factors beyond the Company's control. TransGlobe   does not assume any obligation to update forward-looking statements if   circumstances or management's beliefs, expectations or opinions should   change, other than as required by law, and investors should not   attribute undue certainty to, or place undue reliance on, any   forward-looking statements. Please consult TransGlobe's public filings   at   www.sedar.com and   www.sec.gov/edgar.shtml for further, more detailed information concerning these matters.
