Despite restrictions on travel, constructive negotiations with EGPC to amend, extend and consolidate the Company’s Eastern Desert concession agreements have continued throughout the quarter.

Canada

Consistent with the Company’s revised 2020 budget, there has been no drilling or completion activity during Q2 2020.

The 2-mile horizontal 2-20 well, completed in Q4 2019 and de-risking the South Harmattan fairway, was producing at field estimated rates of 186 Boepd (146 Bopd light oil, 151 Mcf/d gas, 15 Bopd NGL) in June. The Company remains encouraged as the well continues to produce above expectations for this significant new resource play.

TransGlobe’s light oil production continued to be produced at a positive field netback, despite lower crude oil prices in Western Canada early in the quarter, further supported by continued relatively strong natural gas prices. The Company put into service spare oil storage capacity of ~12,000 bbls at our Canadian producing locations during the quarter to take advantage of strength in the forward pricing curve and has retained optionality to bring on flush production in a higher commodity price environment with the deferral of completion operations on the South Harmattan well drilled in the first quarter of 2020.

CORPORATE

The Company has sold ~100,000 bbls oil in each of April and May to EGPC with net proceeds of ~$4.0 million, and expects to continue selling to EGPC at approximately this same monthly rate through the remainder of 2020, supplemented by a physical cargo in Q4 2020.

The Company has collected ~$31.8 million of receivables in Q2 2020 to date, of which ~$21.4 million was from EGPC.

As noted in our Q1 2020 update, the Company repaid $10.0 million on the $75.0 million prepayment facility agreement with Mercuria in April, leaving $20.0 million drawn and outstanding of a revolving balance of up to $75.0 million.

The Company remains forward looking and prepared to use its operational control to take advantage of any sustained upward movement in oil price. TransGlobe continues to be vigilant for attractive M&A opportunities steadfastly retaining its focus on shareholder value creation.

COVID-19

Business continuity plans have been implemented in all our locations and operations continue as normal. The Company has had three reported cases of COVID-19 in its joint venture operating partner in Egypt, which were managed according to established Company and local national quarantine guidelines. All three have recovered and returned to work with no onward infection spread reported.

Oil and Gas Advisories

Mr. Ron Hornseth, B.Sc., General Manager – Canada for TransGlobe Energy Corporation, and a qualified person as defined in the Guidance Note for Mining, Oil and Gas Companies, June 2009, of the London Stock Exchange, has reviewed and approved the technical information contained in this report. Mr. Hornseth is a professional engineer who obtained a Bachelor of Science in Mechanical Engineering from the University of Alberta. He is a member of the Association of Professional Engineers and Geoscientists of Alberta (“APEGA”) and the Society of Petroleum Engineers (“SPE”) and has over 20 years’ experience in oil and gas.

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 NGL: 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.

References in this press release to production test rates, are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will commence production and decline thereafter and are not indicative of long term performance or of ultimate recovery. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for TransGlobe. A pressure transient analysis or well-test interpretation has not been carried out in respect of all wells. Accordingly, the Company cautions that the production test results should be considered to be preliminary.
