OPERATIONS UPDATE

ARAB REPUBLIC OF EGYPT

Western Desert

In South Ghazalat ("SGZ") the Company commenced drilling SGZ 6X, the second exploration well in the concession on October 23rd. SGZ 6X is located on the eastern portion of the concession offsetting the Raml oil field in the Abu Gharadig basin. The SGZ 6X prospect is targeting stacked Cretaceous oil targets similar to the producing Raml and SW Raml fields.

In South Alamein the Company has received notification from the military that access will be granted to drill the South Alamein 24X Jurassic exploration prospect. The Company has submitted the required documentation and is awaiting final written approval which is expected prior to year-end. Concurrently, the Company initiated preparations to drill SA 24X as part of the 2019 exploration program.

Eastern Desert

In West Bakr, the Company drilled a two well infill program in the M field resulting in two oil wells during August/September. The M-North and M-South wells were initially placed on production in September at rates of ~500 Bopd per well. Both of these wells continue to exceed internal pre-drill estimates and are currently producing ~800 Bopd per well following pump optimization work during October.

Following M-South, the rig was moved to NW Gharib 38A-7 to drill a potential water injector in the NWG 38A pool. The NWG 38A-7 well was drilled as a potential water injector targeting the 38A Red Bed pool in a structurally lower position 0.4 kilometers south of the NWG 38A Injector well (NWG 38A-I, drilled Q2). The NWG 38A-I well encountered oil in the targeted Red Bed formation and was placed on production in September at an initial rate of ~110 Bopd (following a fracture stimulation) and is currently producing ~80 Bopd.

The NWG 38A-7 well encountered the Red Bed formation, which appears to contain both oil and water, however the well was cased, due to deteriorating wellbore conditions prior to acquiring definitive fluid samples. The NWG 38A-7 well will be completed during November and depending on the production results will be another oil producer or converted to water injection well to support the NWG 38A oil pool. In the event NWG 38A-7 is an oil producer, the Company has planned an additional well (NWG 38A-8) further south as a contingency for reservoir pressure support.

CANADA

In Canada, the Company commenced drilling the 2018 Cardium development program, which includes six gross (five net) horizontal Cardium development wells to be drilled from a common pad to improve efficiencies and reduce costs. The Company has drilled and cased three one-mile horizontal wells and the Company's first two-mile horizontal well. The Company is currently drilling the fifth horizontal well of the six well program. Upon completion of the six well development drilling program, the Company is targeting to complete the wells during the fourth quarter, with first production from the multi-well pad by year-end/early January.

In addition, the Company will drill a one-mile horizontal well during the fourth quarter to evaluate a portion of the newly acquired lands (16 net sections (10,240 acres) of Cardium prospective acreage) located south/south west of the Harmattan pool. If successful, the new lands could provide a significant development opportunity which is proximal to the Company's Harmattan production and facilities. The Harmattan Cardium pool has typically been developed by drilling four one mile horizontal wells per section.

Oil and Gas Advisories

Mr. Brett Norris, M.Sc., P Geo, - Vice President Exploration 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 announcement. Mr. Norris obtained a Master's of Science Degree in Geology from the University of Western Ontario. He is a Registered Professional Geoscientist in the province of Alberta and has over 30 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.

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.

Certain type curve information included to in this news release, including IP30, represents estimates of the production decline and ultimate volumes expected to be recovered from wells over the life of the well. This information is based on management-generated type curves based on a combination of historical performance of older wells and management's expectation of what might be achieved from future wells. The information represents what management thinks an average well will achieve. Individual wells may be higher or lower but over a larger number of wells management expects the average to come out to the type curve. Over time type curves can and will change based on achieving more production history on older wells or more recent completion information on newer wells.

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

Bopd barrels of oil per day

MBopd thousand barrels of oil per day

Boepd barrels of oil equivalent per day

MBoepd thousand barrels of oil equivalent per day
