("Zenith" or the "Company")

Workover of ROB-1, onshore Tunisia

Zenith Energy Ltd. ("Zenith" or the "Company") (LSE: ZEN; OSE: ZENA), the listed international energy production and development company, is pleased to provide an update regarding the ongoing workover of the Robbana-1 well (“ROB-1”), located in the Robbana concession, onshore Tunisia.

Workover of ROB-1

Zenith is pleased to report that the workover of ROB-1 is progressing successfully.

As last announced on September 6, 2021, ROB-1 has not undergone any form of well intervention since 2012 and was producing at a stabilised rate of approximately 20 bopd prior to the commencement of workover operations.

The well completion string has been fully pulled out of the wellbore, encountering approximately 200 hundred meters of paraffin and wax deposits cleared by way of reverse circulation using diesel fuel.

The Company will now proceed with bottom hole cleaning and scraping of the casing to be followed by the installation of a new tubing anchor and sucker rod pump supplied by Weatherford.

ROB-1 operations are expected to be concluded during the next 10 days.

In the event of a successful outcome, the Company is expecting a new stabilised production rate in a range between approximately 60-80 bopd.

Andrea Cattaneo, Chief Executive Officer of Zenith, commented:

“The team looks forward to successfully completing Zenith’s first well intervention in Tunisia. A projected increase of approximately 40-60 barrels of oil per day will, in the current high oil price environment, result in significant additional revenue and associated profitability.

We are very pleased with our recent progress and expect to soon be in a position to update shareholders on our other key development milestones.”
