OPERATIONS UPDATE

AIM & TSX: "TGL" & NASDAQ: "TGA"

Calgary, Alberta, April 6, 2022 - TransGlobe Energy Corporation ("TransGlobe" or the "Company") announces an operations update. All dollar values are expressed in US dollars unless otherwise stated.

OVERVIEW

·      Production averaged 12.4 MBoepd in Q1, 2022 (See "Oil & Gas Advisories" for production by product type);

·   Two 100% working interest (one 2-mile, one 1-mile) Canada Harmattan horizontal Cardium reservoir development wells were drilled in Q1, 2022;

·      Drilled and cased three Egypt Eastern Desert development wells in Q1, 2022;

·      Production has been restored at the South Ghazalat SGZ-6X well;

·      A cargo of Egypt crude oil is scheduled to lift through the end of April and into early May;

·      The Company ended Q1, 2022 with ~$37 million cash.

RANDY NEELY, PRESIDENT AND CEO'S STATEMENT

"We achieved a solid operational start to the year with drilling in both Egypt and Canada generating production in line with guidance, and we have opportunistically retained the Canadian rig to accelerate the budgeted seven well drilling program as demand for services and equipment increases.

Corporately, a second quarter lifting is a testament to the continued alignment between Egyptian General Petroleum Corporation ("EGPC") and ourselves following the signing of the merged concession agreement in January 2022. We continue to work closely with EGPC to finalize the effective date adjustment to be paid to TransGlobe.

With operations well in hand, the reinstated dividend, continued strong commodity prices, and a distribution policy to allocate a minimum of 75% of our annual free cash flow to shareholders through dividends and share buybacks, TransGlobe's outlook for 2022 and beyond is very encouraging."

PRODUCTION

Production Summary (WI before royalties and taxes):

* See "Oil & Gas Advisories" for production by product type.

Corporate production in Q1 remains in line with 2022 annual guidance of 12.4-13.4 MBoepd. In Egypt production was impacted by poor weather in February and higher water cuts than anticipated at South Ghazalat. As expected, Canadian base production declined over the quarter with the fall-off in initial flush production from the horizontal wells brought onstream in Q4, 2021. Canadian production was also restricted in January and February due to extreme cold weather, while the planned shut-in of the highly productive 4-2 horizontal well during drilling operations on the 15-11 surface location negatively impacted March production.

OPERATIONS UPDATE

Arab Republic of Egypt

Eastern Desert (100% WI)

The Company continued to use the EDC-64 rig in its Eastern Desert drilling campaign, managing to drill and case three additional development wells in K-Field, Arta Field and NWG-Field during the quarter.

The K-68 well, drilled at the end of 2021, was completed in the Asl-A reservoir in January as previously reported in the Company's January 10, 2022, operations update. It is currently producing at a rate of 156 Bopd (heavy crude, field estimate).

K-67 was drilled to a total depth of 1,440 meters, and was fully logged and evaluated. The well encountered an internally estimated 16 meters of net oil pay in the Asl-A and 17 meters of net oil pay in the Asl-B.  The well was completed in the Asl-B and is currently on production at a rate of 174 Bopd (heavy crude, field estimate).

Arta-76 was drilled to a total depth of 1,074 meters and was fully logged and evaluated.  The well encountered an internally estimated 12 meters of net oil pay in the Nukhul reservoir.

NWG-1E was drilled to a total depth of 1,219 meters and encountered 9 meters of oil pay in the Nukhul reservoir after being fully logged and evaluated.

Both Arta-76 and NWG-1E will be stimulated as part of a multi-well stimulation campaign in Q2, 2022, subsequent to which they will be put on production.

The K-71 well was drilled to a total depth of 1,448 meters and was fully logged and evaluated.  The well encountered an internally estimated 19 meters of net oil pay in the Asl-A reservoir and 23 meters of net oil pay in the Asl-B reservoir.  The well is currently being completed and will be put on production in April 2022.

Following K-71, the EDC-64 rig will move to the K-78 well.

The Company is currently working to proactively mitigate potential supply chain issues brought about by the conflict in Ukraine and the resultant sanctions by engaging alternative materials suppliers.  To date, TransGlobe's operations have not been impacted by any material shortages.

Western Desert - South Ghazalat (100% WI)

Following the cessation of natural flow of SGZ-6X well at South Ghazalat in December 2022 due to low reservoir pressure, a rigless artificial lift system was successfully deployed to restore production. On artificial lift, the lower Bahariya reservoir at SGZ-6X is currently producing at 88 Bopd of light crude oil with an 89% watercut (field estimate).

Canada

Two 100% working interest (one 2-mile, and one 1-mile) Harmattan horizontal Cardium reservoir wells were drilled in the South Harmattan area of our Canada land holdings, with stimulation and equipping anticipated in June 2022.

The Company has moved the rig on the 15-11 surface location in anticipation of spudding another 100% working interest 2-mile Harmattan horizontal Cardium reservoir well in mid-April, to take advantage of a favorable rig rate and rig availability.

CORPORATE

The Company has a cargo of Gharib blend crude scheduled to ship at the end of April through early May, with proceeds expected in June, 2022.

TransGlobe ended Q1, 2022 with ~$37 million of cash and $3.1 million outstanding under its RBL facility.

An updated corporate presentation has been posted to the Company's website.

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 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 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.

Further, this press release includes estimates of pay thickness and production rates in the K-Field, Arta-Field and NWG-Field in the Eastern Desert of Egypt (100% WI), which are considered to be anticipated results or information that indicate the potential value or quantities of resources under National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities because the disclosure in question may, in the opinion of a reasonable person, indicate the potential value or quantities of resources in respect of the Company's resources or a portion of  its  resources. Such estimates have been prepared internally by management of TransGlobe and have not been prepared or reviewed by an independent qualified reserves evaluator or auditor.  Anticipated results are subject  to  certain  risks  and  uncertainties,  including  those  described  above under "Advisory on Forward-Looking Information and Statements" and various geological, technical,  operational,  engineering,  commercial,  and  technical  risks, including, but not limited to, the risk that TransGlobe's exploration and development drilling and related activities may provide different results; the risk that TransGlobe may encounter unexpected drilling results; the occurrence of unexpected events involved in the exploration for, and the operation and development of, oil and gas; delays in anticipated timing of drilling and completion of wells; geological, technical, drilling and processing problems and other difficulties in producing petroleum reserves; and the risk that if any resources are discovered that it will not be commercially viable to produce any portion thereof. In addition, the geotechnical analysis and engineering to be conducted in respect of such resources is not complete. Such risks and uncertainties may cause the anticipated results disclosed herein to be inaccurate. Actual results may vary, perhaps materially. There is no certainty that TransGlobe will achieve the anticipated results from the K-Field and H-Field in the Eastern Desert of Egypt or that any resources will be discovered. If discovered, there is also no certainty that it will be commercially viable to produce any portion of the resources.

References in this press release to initial production rates are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will continue production 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 production test results and initial production results should be considered to be preliminary.
