Well 7D Update

PetroTal has successfully completed the 7D well, the Company's seventh in the Bretana oil field, and first new well of 2021. The well was a deviated hole and penetrated the targeted Vivian formation in excellent quality sands. Total vertical depth of 2,696 meters was reached. The well achieved an initial 10-day average flow rate of 3,700 bopd, which was in line with management's expectations, and is currently producing approximately 4,550 bopd. Total drilling time was 33 days and the well cost approximately $8.6 million, 7% under the $9.2 million estimate. This was the first well executed under PetroTal's enhanced COVID-19 safety protocols and no safety issues were encountered during the operation.

The 7D well sets the stage for the Company to again grow production, with the field currently averaging approximately 11,100 bopd, and the goal of ending 2021 at 18,000 to 19,000 bopd. Overall field production would be approximately 12,300 bopd, inclusive of two wells, representing approximately 1,200 bopd, currently shut in to accommodate water injection enhancements.

3WD Water Disposal Well

The next well, 3WD, commenced drilling on May 3, 2021 and will take approximately 41 days to drill and complete. The Vivian reservoir will be cored, providing important reservoir characterization data for future field development. This future water disposal well will enable the disposal of an additional 50,000 barrels of water per day and will accommodate the Company's expected production growth for at least the following fourteen months.

VP Exploration and Development Change

Effective May 11, 2021 the Company is pleased to announce the appointment of Mr. Dewi Jones to VP Exploration and Development. Mr. Jones is a geologist with over 35 years of experience in Peru and other Latin American basins. Mr. Jones started his career with Occidental Petroleum in Colombia and has also led technically complex development programs for Repsol, Talisman and Pioneer. Mr. Jones was formerly CEO of CGX Energy, having exploration blocks in Guyana adjacent to Exxon's Liza discovery. Mr. Jones is a graduate of Louisiana State University with a B.Sc. in Geology. Prior to this appointment, Mr. Jones was the Director of Exploration and Development with PetroTal and collaborated with Mr. Alvarez-Calderon on many technical aspects over recent months, ensuring a smooth transition of knowledge and culture.

Effective May 31, 2021, Mr. Estuardo Alvarez-Calderon will retire from the Company. Mr. Alvarez-Calderon was instrumental in leading PetroTal from a technical perspective, taking PetroTal from zero to over 13,000 bopd in late 2019 and identifying numerous leads and prospects in both Blocks 95 and 107 for continued organic growth. The Company thanks Mr. Alvarez-Calderon for his significant contributions to PetroTal and wishes him a well-earned and restful retirement.

AGM Update and Q1 2021 Results

PetroTal will release its Q1 2021 financial and operating results on May 31, 2021 to be followed by a webcast presentation on June 1, 2021. Details for the event will be announced over the coming weeks. An updated corporate presentation will also be released.

PetroTal advises that its annual general and special meeting of shareholders will be held via webcast on June 23, 2021 at 10:00 a.m. (Calgary time). Details of the agenda and a link to the meeting will be included in the Company's management information circular to be mailed to registered shareholders and SEDAR filed on May 24, 2021.

Manuel Pablo Zuniga-Pflucker, President and Chief Executive Officer, commented:

"On behalf of the PetroTal team, I would like to personally thank Estuardo for his contributions to the Company. Estuardo's achievements in his career and at PetroTal have been remarkable and his presence in the office will be missed. I am very excited about Dewi Jones stepping in to fill Estuardo's role. Dewi has been working with PetroTal for some time and the entire management team has a deep trust and confidence in his work and experience.

It is very exciting as a management team to be bringing the new 7D well on for the Company after almost a year lag from completion of the 6H well. The stabilized flow rates of approximately 4,550 bopd look very promising and are in line with our technical estimates. Continuing with our development plan, we commenced drilling the 3WD well that will greatly increase our water disposal capacity."

Dewi Jones, the Company's VP, Exploration and Development, who has over 35 years of relevant experience in the oil industry, has approved the technical information contained in this announcement. Mr. Jones received a Bachelor of Science degree in Geology from Louisiana State University (LSU) and is registered on the Texas Board of Professional Geoscientists.

FORWARD-LOOKING STATEMENTS: This press release contains certain statements that may be deemed to be forward-looking statements. Such statements relate to possible future events, including, but not limited to: PetroTal's business strategy, objectives, strength and focus; drilling, completions, workovers and other activities and the anticipated costs and results of such activities; the ability of the Company to achieve drilling success consistent with management's expectations; anticipated future production and revenue; drilling plans including the timing of drilling; oil production levels; COVID-19 surveillance and control process; future development and growth prospects; and the timing of Q1 2021 filings. All statements other than statements of historical fact may be forward-looking statements. In addition, statements relating to expected production, reserves, recovery, costs and valuation are deemed to be forward-looking statements as they involve the implied assessment, based on certain estimates and assumptions that the reserves described can be profitably produced in the future. Forward-looking statements are often, but not always, identified by the use of words such as "anticipate", "believe", "expect", "plan", "estimate", "potential", "will", "should", "continue", "may", "objective" and similar expressions. The forward-looking statements are based on certain key expectations and assumptions made by the Company, including, but not limited to, expectations and assumptions concerning the ability of existing infrastructure to deliver production and the anticipated capital expenditures associated therewith, reservoir characteristics, recovery factor, exploration upside, prevailing commodity prices and the actual prices received for PetroTal's products, including pursuant to hedging arrangements, the availability and performance of drilling rigs, facilities, pipelines, other oilfield services and skilled labour, royalty regimes and exchange rates, the application of regulatory and licensing requirements, the accuracy of PetroTal's geological interpretation of its drilling and land opportunities, current legislation, receipt of required regulatory approval, the success of future drilling and development activities, the performance of new wells, the Company's growth strategy, general economic conditions and availability of required equipment and services. Although the Company believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because the Company can give no assurance that they will prove to be correct. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. These include, but are not limited to, risks associated with the oil and gas industry in general (e.g., operational risks in development, exploration and production; delays or changes in plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses; and health, safety and environmental risks), commodity price volatility, price differentials and the actual prices received for products, exchange rate fluctuations (including volatility of the Peruvian Sol), legal, political and economic instability in Peru (including in respect of the Peruvian election), access to transportation routes and markets for the Company's production, changes in legislation affecting the oil and gas industry and uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. In addition, the Company cautions that current global uncertainty with respect to the spread of the COVID-19 virus and its effect on the broader global economy may have a significant negative effect on the Company. While the precise impact of the COVID-19 virus on the Company remains unknown, rapid spread of the COVID-19 virus may continue to have a material adverse effect on global economic activity, and may continue to result in volatility and disruption to global supply chains, operations, mobility of people and the financial markets, which could affect interest rates, credit ratings, credit risk, inflation, business, financial conditions, results of operations and other factors relevant to the Company. Please refer to the risk factors identified in the Company's annual information form for the year ended December 31, 2020 and management's discussion and analysis for the year ended December 31, 2020, which are available on SEDAR at www.sedar.com. The forward-looking statements contained in this press release are made as of the date hereof and the Company undertakes no obligation to update publicly or revise any forward-looking statements or information, whether as a result of new information, future events or otherwise, unless so required by applicable securities laws.
