TransGlobe Energy Corporation Announces 2016 Year-End Reserves

CALGARY, ALBERTA--(Marketwired - Jan. 25, 2017) - TransGlobe Energy Corporation ("TransGlobe" or the "Company") (TSX:TGL) (NASDAQ:TGA) today announces its 2016 year-end reserves. All dollar values are expressed in United States dollars unless otherwise stated.

EXECUTIVE SUMMARY

  • Total proved ("1P") gross reserves increased 71% from year-end 2015 to 29.9 million barrels oil equivalent ("MMboe")
  • Total proved plus probable ("2P") gross reserves also increased 74% from year-end 2015 to 50.0 MMboe noting the following:
    • Canadian acquisition added 20.7 MMboe of gross 2P reserves net of production including 46 BCF 2P of conventional natural gas.
    • Positive technical additions of 5.2 MMbbls of gross 2P reserves primarily attributed to the Arta Red Bed pool performance/ simulation results and performance at West Gharib, West Bakr.
    • Replaced 116% of 2016 production (~4.5 MMboe).
    • At year-end 2016, 2P reserves were comprised of 59% Egypt medium/ heavy oil, 15% Canada conventional natural gas, 16% Canada natural gas liquids and 10% Canada light oil.
  • Total proved plus probable plus possible ("3P") gross reserves increased 65% from year-end 2015 to 65.9 MMboe.
  • 2016 year-end after tax future net revenues of $338MM (2P reserves discounted at 10%, forecast pricing), a 73% increase from year-end 2015.

RESERVES

The Company's 2016 and 2015 year-end reserves were prepared by DeGolyer and MacNaughton Canada Limited ("DeGolyer"), an independent qualified reserves evaluator, in accordance with National Instrument 51-101 and the Canadian Oil and Gas Evaluation Handbook.

The following is a summary of DeGolyer's evaluation for the year ended December 31, 2016 dated January 18, 2017 (the "DMCL Report"). The recovery and reserve estimates of crude oil, natural gas liquids ("NGLs") and conventional 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 conventional natural gas reserves may be greater than, or less than, the estimates provided herein. All 2016 year end reserves presented are based on DeGolyer's forecast pricing, effective December 31, 2016.

The following tables may not total due to rounding.

Note:
1. The pricing assumptions used in the DMCL report with respect to the net present value of future net revenue (forecast) as well as the inflation rates used for operating and capital costs are set forth below. See "Forecast Prices used in Estimates".
2. Net reserves are the Company's working interest share after the deduction of royalties. Net reserves in Egypt include the Company's share of future cost recovery and production sharing oil after the Government's royalty based interest but before reserves relating to income taxes payable. Under this method, a portion of the reported reserves will increase as oil prices decrease (and vice versa) as the barrels necessary to achieve cost recovery change with prevailing oil prices.
3. Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves.

2016 Reserve Changes

Reserves at 2016 year-end were higher compared to 2015 year-end primarily due to the Canadian acquisition (see press release dated December 5, 2016) and positive revisions of the Arta Red Bed pool performance/ technical revisions in addition to positive performance revisions in West Bakr. The Company drilled three development wells (two in K-South and one in the Arta Red Bed) all of which resulted in undeveloped reserve assignments as of the mid-year 2016 reserve update. One additional Arta Red Bed development well was drilled and rig released subsequent to December 31, 2016. Egypt 2016 production was replaced by the positive technical revisions in West Gharib and West Bakr concessions. In addition, the Company filed for and received its first development lease in Northwest Gharib. Production from the NWG 3X well commenced prior to year-end 2016, representing a reserve conversion from proved undeveloped to proved producing.

The Canadian acquisition materially added to the Company's 1P, 2P and 3P working interest reserves. The addition of conventional natural gas reserves represents approximately 15% on a boe basis of the Company's total 2P reserve assignment as of December 31, 2016.

Estimated Future Net Revenues

All evaluations and reviews of future net revenues 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 revenues shown below are 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.

The estimated future net revenues for the years December 31, 2016 and 2015 presented below in millions of U.S. dollars ($MM), are calculated using DeGolyer's price forecasts at December 31, 2016 and December 31, 2015 respectively. The increase in future net revenues is primarily due to higher reserves and lower Egypt operating costs at year end 2016 offset by marginally higher pricing differentials at West Gharib, West Bakr and Northwest Gharib.

All dollar amounts set forth in the tables below are in USD.

Forward-looking statements or information typically contain statements with words such as "anticipate", "believe", "expect", "plan", "intend", "estimate", "may", "will", "would" or similar words suggesting future outcomes or statements regarding an outlook. In particular, forward-looking information and statements contained in this document include, but are not limited to, statements relating to "reserves" which are, by their nature, forward-looking statements, as they involve the implied assessment, based on certain estimates and assumptions that the reserves or resources, as applicable, described exist in the quantities predicted or estimated and that the reserves can be profitably produced in the future. The recovery and reserve estimates of TransGlobe's reserves provided herein are estimates only and there is no guarantee that the estimated reserves will be recovered. Forward-looking statements or information are based on a number of factors and assumptions which have been used to develop such statements and information but which may prove to be incorrect. Although the Company believes that the expectations reflected in such forward-looking statements or information are reasonable, undue reliance should not be placed on forward-looking statements because the Company can give no assurance that such expectations will prove to be correct. Many factors could cause TransGlobe's actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, TransGlobe.

In addition to other factors and assumptions which may be identified in this news release, assumptions have been made regarding, among other things, anticipated production volumes; the timing of drilling wells and mobilizing drilling rigs; the number of wells to be drilled; the Company's ability to obtain qualified staff and equipment in a timely and cost-efficient manner; the regulatory framework governing royalties, taxes and environmental matters in the jurisdictions in which the Company conducts and will conduct its business; future capital expenditures to be made by the Company; future sources of funding for the Company's capital programs; geological and engineering estimates in respect of the Company's reserves and resources; the geography of the areas in which the Company is conducting exploration and development activities; current commodity prices and royalty regimes; availability of skilled labour; future exchange rates; the price of oil; the impact of increasing competition; conditions in general economic and financial markets; availability of drilling and related equipment; effects of regulation by governmental agencies; future operating costs; uninterrupted access to areas of TransGlobe's operations and infrastructure; recoverability of reserves and future production rates; that TransGlobe will have sufficient cash flow, debt or equity sources or other financial resources required to fund its capital and operating expenditures and requirements as needed; that TransGlobe's conduct and results of operations will be consistent with its expectations; that TransGlobe will have the ability to develop its properties in the manner currently contemplated; current or, where applicable, proposed industry conditions, laws and regulations will continue in effect or as anticipated as described herein; that the estimates of TransGlobe's reserves and resource volumes and the assumptions related thereto (including commodity prices and development costs) are accurate in all material respects; and other matters.

Forward-looking statements or information are based on current expectations, estimates and projections that involve a number of risks and uncertainties which could cause actual results to differ materially from those anticipated by the Company and described in the forward-looking statements or information. These risks and uncertainties which may cause actual results to differ materially from the forward-looking statements or information include, among other things, operating and/or drilling costs are higher than anticipated; 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 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; competition; lack of availability of qualified personnel; the results of exploration and development drilling and related activities; obtaining required approvals of regulatory authorities; volatility in market prices for oil; fluctuations in foreign exchange or interest rates; environmental risks; ability to access sufficient capital from internal and external sources; failure of counterparties to perform under the terms of their contracts; and other factors beyond the Company's control. Readers are cautioned that the foregoing list of factors is not exhaustive. Please consult TransGlobe's public filings at www.sedar.com and www.sec.gov/edgar.shtml for further, more detailed information concerning these matters, including additional risks related to TransGlobe's business.

The forward-looking statements or information contained in this news release are expressly qualified by this cautionary statement.

Oil & Gas Information

Certain Defined Terms

"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 are those additional reserves that are less certain to be recovered than probable reserves. There is a 10% probability that the actual remaining quantities recovered will equal or exceed the sum of the estimated proved + probable + possible reserves.

"Gross Reserves" are the Company's working interest (operating and non-operating) share before deduction of royalties and without including any royalty interests of the Company.

"Net Reserves" are the Company's working interest share after the deduction of royalties. Net reserves in Egypt include the Company's share of future cost recovery and production sharing oil after the Government's royalty based interest but before reserves relating to income taxes payable. Under this method, a portion of the reported reserves will increase as oil prices decrease (and vice versa) as the barrels necessary to achieve cost recovery change with prevailing oil prices.

"Developed" reserves are those reserves that are expected to be recovered from existing wells and installed facilities or, if facilities have not been installed, that would involve a low expenditure (e.g. when compared to the cost of drilling a well) to put the reserves on production.

"Developed Producing" reserves are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption or production must be known with reasonable certainty.

"Developed Non-Producing" reserves are those reserves that either have not been on production, or have previously been on production, but are shut-in, and the date of resumption is unknown.

"Undeveloped" reserves are those reserves expected to be recovered from known accumulations where a significant expenditure (for example, when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves classifications (proved, probable, possible) to which they are assigned.

This press release discloses estimates of light and medium crude oil and heavy oil. Light crude oil is crude oil with a relative density greater than 31.1 degrees API gravity, medium crude oil is crude oil with a relative density greater than 22.3 degrees API gravity and less than or equal to 31.1 degrees API gravity, and heavy crude oil is crude oil with a relative density greater than 10 degrees API gravity and less than or equal to 22.3 degrees API gravity.

BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet of natural gas to one barrel of oil equivalent (6 mcf: 1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

The discounted and undiscounted net present value of future net revenues attributable to the reserves disclosed herein do not represent the fair market value of such reserves. The estimates of reserves and future net revenue for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation.

This press release contains a number of oil and gas metrics, including the percentage replacement of 2016 production, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods. Replacement of production ratio is defined as the change in period reserves excluding economic and acquisition and divestures factors divided by the period production.

The following abbreviations used in this press release have the meanings set forth below:

bbls barrels
MMbbls million barrels
boe barrels of oil equivalent of natural gas, on the basis of one barrel of oil or NGLs for six thousand cubic feet of natural gas
MMboe million of barrels oil equivalent
NPV net present value of future net revenues
mcf thousand cubic feet
Bcf billion cubic feet
NGL Natural Gas Liquids
