TransGlobe Energy Corporation announces 2012 year-end contingent resources and propsective resource evaluation

Wednesday, January 30, 2013
  • Best Case Contingent Resources of 2.0 million barrels.
  • The Mean estimate of total undiscovered oil initially in place ("UPIIP") for the 38 evaluated prospects is 1 billion barrels.

TransGlobe Energy Corporation (TSX:TGL) (NASDAQ:TGA) ("TransGlobe" or the "Company") today announced its 2012 year-end contingent resources. In addition the Company is pleased to announce the results of an independent prospective resource evaluation of 38 individual oil prospects located in the Egyptian Western Desert within the South Alamein (100% WI), South Mariut (60% WI) and East Ghazalat (50% WI) exploration concessions.

The Company's 2012 year-end contingent resources and the prospective resource evaluations were prepared by the independent reserves evaluation firm of DeGolyer and MacNaughton Canada Limited ("DMCL"). Both evaluations were performed in accordance with National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities Section 5.9 ("NI 51-101") and the Canadian Oil and Gas Evaluation Handbook ("COGEH") Volume 1, and are effective December 31, 2012.

All dollar values are expressed in United States dollars unless otherwise stated.

CONTINGENT RESOURCE HIGHLIGHTS

  • Best Case Contingent Resources of 2.0 million barrels
  • Estimated Future Net Revenue for Best Case Contingent Resource is $29.1 million (at 10% discounting)

PROSPECTIVE RESOURCE HIGHLIGHTS

  • The Mean estimate of total undiscovered oil initially in place ("UPIIP") for the 38 evaluated prospects is 1 billion barrels
  • The Mean estimate of total Prospective Resource is 200 million barrels
  • The Mean estimate of total Working Interest Prospective Resource is 170 million barrels
  • Company announced a 2013 Capital program (December 11, 2012), which includes exploration wells to evaluate 10 of the 38 prospects in the report. The planned 10 wells will evaluate approximately 75 of the 170 million barrels (44%) of Mean Working Interest Prospective Resources during 2013.

CONTINGENT RESOURCES

The following is a summary of DMCL evaluation for the year ended December 31, 2012. The Company did not have Contingent Resources evaluated at year ended December 31, 2011. The recovery and contingent resource estimates of crude oil, natural gas liquids ("NGLs") and natural gas resources provided in this news release are estimates only, and there is no guarantee that the estimated resources will be recovered. Actual crude oil, NGL and natural gas resources may be greater than, or less than, the estimates provided herein. All Contingent Resources presented are based on DMCL forecast pricing effective December 31, 2012.

Contingent Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. There is no certainty that it will be commercially viable to produce any portion of the resources.

Uncertainty Ranges as described by the COGEH handbook as low, best and high estimates for resources as follows:

Low Estimate: this is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate.

Best Estimate: This is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate.

High Estimate: This is considered to be an optimistic estimate of the quantity that will be actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate.

Contingencies

In Egypt, Contingent Resources were assigned to the Boraq 2 oil discovery in the South Alamein concession which was acquired in 2012. The Contingent Resources assigned to Boraq are contingent on the approval of a development plan. During 2012 the Company prepared and submitted an eight well drilling program for approvals, which includes two appraisal/development wells at Boraq and six exploration wells on the concession. Upon receiving the necessary approvals, the Company plans to proceed with the appraisal/development of the Boraq 2 discovery in 2013.

In Yemen, Reserve volumes which had historically been assigned to the Osaylan oil pool in Block S-1 were removed from the Company Reserves and reclassified as Contingent Resources at year-end 2012. The assigned Contingent Resources are contingent on future drilling which has been curtailed in the area due to political instability and related security issues.

Contingent Resources 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 resources 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 resource estimates of crude oil, NGL and natural gas resources provided herein are estimates only, and there is no guarantee that the estimated resources will be recovered. Actual crude oil, NGL and natural gas resources may be greater than or less than the estimates provided herein.

The estimated future net revenues for year ended 2012 presented below in millions of U.S. dollars ("$MM") are calculated using DMCL price forecast at December 31, 2012 and constant pricing for 2012. In the constant price case, the prices were held constant for the life of the resources.
