·    The combination of the recent equity financing and credit facility expansion, uniquely positions Southern to execute a meaningful growth strategy

Ian Atkinson, President and CEO of Southern, commented:

"We are pleased with the success of our recent equity financing, which allows us to accelerate the organic growth strategy portion of our goal to reach 25,000 boe/d. The success of these first three wells at Gwinville have already increased our corporate production by over 100%. We are truly excited by our ability to begin a long-term development drilling program to unlock shareholder value due to the significant reserves, production and cashflow growth in Gwinville and our other assets. Cashflow generated from this development will support our fundamental strategy of both organic and inorganic growth of natural gas weighted assets in the Gulf Coast area of the United States."

Capital Budget

Based on the success of the initial three well appraisal program at Gwinville, Southern's Board of Directors has approved an accelerated capital budget of US$34.4 million for the balance of 2022, which will allow the Company to commence a long-term drilling program beginning in Q4 2022 in the Gwinville field. Major services and equipment have been secured for the development program to optimize capital and operational efficiencies. The approved drilling program will target multi-zone horizontal potential in the Upper Selma, Lower Selma and City Bank formations with a further five horizontal wells, as well as pad construction, in-field pipelines and water disposal well conversions that will help service the next few years of Gwinville development.  Management expects to have the first pad of three horizontal wells on stream prior to year-end but with limited production.

In the upcoming program the Company will drill at least one Lower Selma Chalk horizontal well and one City Bank horizontal well to prove the deliverability of these high remaining gas-in-place reservoirs.  Neither of these horizons have undeveloped reserves booked despite having historic vertical and horizontal success from the same era as the first-generation Selma Chalk wells. It is management's expectation that proving success in these formations will lead to material reserves additions for the Company.  At current gas pricing, and using the older Gen 2 type curve, these Gwinville horizontal wells are expected to pay out in less than 12 months, allowing the Company to self fund further drilling campaigns in its assets expected to follow in 2023.

Operations Update

Southern was successful in safely and efficiently executing the three well appraisal program in the first half of 2022, marking the first horizontal drilling activity in the Gwinville Field in approximately 12 years. The primary goal of the appraisal program was to reaffirm the remaining recoverable gas-in-place in the Selma Chalk reservoir by proving the successful application of advanced completion technology ("Gen 3" design). The three wells were drilled, completed, equipped and tied-in within 20% of originally budgeted estimates despite industry wide inflationary pressures that were well in excess of that figure.

Highlights

·    Growth strategy to reach 25,000 boe/d is solidified with the US$34.4 million capital budget being the catalyst for the Company to commence a self-funded, long-term drilling program from Q4 2022 onwards at Gwinville field

·    Natural gas sales at the Transco Zone 4 hub realizing an index price of > US$13 per MMbtu for August, reflecting approximately US$5.00 per MMBtu premium to NYMEX. Futures contracts suggests that a continuation of this positive basis differential is forecasted for at least the next few years.

·    The three Gwinville Upper Selma Chalk wells have now successfully achieved a combined IP30 gas rate of 14.1 MMcf/d (2,350 boepd), adding significant unhedged production to the Company during these strong market conditions, bringing total early August Company production up to approximately 22.1 MMcfe/d (3,680 boepd) (96% natural gas):

-      GH 19-3 #2 well achieved a rate of 6.5 MMcf/d (1,083 boepd), exceeding the older Generation 2 ("Gen 2") type curve IP30 forecast of 5.7 MMcf/d (950 boepd)

-      GH 19-3 #3 and GH 19-3 #4 wells achieved IP30 gas rates of 3.6 and 4.0 MMcf/d (600 boepd and 670 boepd), respectively, despite only 50% of the horizontal lateral in both wells being in the high-grade Upper Selma Chalk interval

-      Estimated July 2022 revenue for the three well padsite of over $3.6 million.

The three Gwinville Upper Selma Chalk horizontal wells have achieved an average IP30 gas rate (first 30 days of production following recovery of 20% load fluid) of 4.7 MMcf/d.  A subsequent, comprehensive look-back analysis of the program, including a full 3D seismic re-interpretation, has significantly improved the Company's ability to model the structural complexity of the reservoir and identify the optimal drill path of future horizontal laterals.  Furthermore, the planned Q4 2022 drilling program will utilize rotary steerable drilling technology which will also optimize both directional steering precision and performance.

By implementing the appraisal program learnings, the Company is highly confident that future Upper Selma Chalk wells can successfully achieve > 80% lateral length within the high-grade porosity interval. When the production results from the GH 19-3 #3 and GH 19-3 #4 wells are normalized to account for effective lateral length, the rates closely mirror the GH 19-3 #2 well that successfully stayed in the target interval for > 90% of the horizontal lateral.

With the Gen 3 stimulation design that increased stage counts by > 275% and proppant concentrations by > 40% compared to the Gen 2 design of 8-10 years ago, the Company believes that the ultimate recoverable gas from these three wells will be superior to earlier wells. By optimizing the lateral length in the targeted high-grade Upper Selma Chalk interval in future wells, the Company expects to replicate the GH 19-3 #2 results.  As the Company obtains three and six month production histories, the Company will present updated type curve forecasts that will assist in modelling future production growth. With the successful results of the Gen 3 appraisal program, the Company expects to add material 1P and 2P reserves to the Gwinville Field with the year end 2022 reserves report, expected to be published during Q1 2023.

Outlook

Southern has secured the equipment and major services necessary to begin the next phase of drilling at Gwinville in Q4 2022.  Southern intends to strategically and efficiently deploy cash from the recent equity financing to capitalize on the strong natural gas pricing in the Southeastern U.S. and robust economics at the Gwinville field, to materially grow the Company organically over the coming years.

Natural gas pricing has remained strong in the Southeastern U.S. spot and forward basis markets highlighted by the recent August 2022 settlement price where a portion of Southern's natural gas is selling for approximately US$5.00 per MMBtu premium to NYMEX. In recent weeks, this region has had the highest priced natural gas market in the U.S. and futures markets indicate premiums to NYMEX extending out to 2026.  At current pricing the Company's development drilling at Gwinville is expected to payout in far less than 12 months.  The Company continues to monitor these premium prices and is prepared to hedge additional basis exposure at these elevated basis premiums.

Calvin Yau, Chief Financial Officer of Southern, commented:

"The strength of natural gas spot and basis pricing premiums to NYMEX in Southeastern U.S. has continued positively over the past month. Our long-term drilling program will add new unhedged production allowing Southern and its shareholders to realize significant additional value, from sales made at premiums to NYMEX."

The Company's long-term strategy remains consistent, with an unwavering commitment to environmental, social and governance ("ESG") principles that support the continued development and consolidation of prolific reservoirs that are outside of the more expensive shale basins. Cost savings and financial discipline will remain a priority through the continued enhancement of operations and the ongoing evaluation of opportunities to reduce operating and capital costs.

Southern thanks all of its stakeholders for their ongoing support and looks forward to providing future updates on operational activities.

READER ADVISORY

MCFE Disclosure. Natural gas liquids volumes are recorded in barrels of oil (bbl) and are converted to a thousand cubic feet equivalent (Mcfe) using a ratio of six (6) thousand cubic feet to one (1) barrel of oil (bbl). Natural gas volumes recorded in thousand cubic feet (Mcf) are converted to barrels of oil equivalent (boe) using the ratio of six (6) thousand cubic feet to one (1) barrel of oil (bbl). Mcfe and boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl or a Mcfe conversion ratio of 1 bbl:6 Mcf is based in an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In addition, given that the value ratio based on the current price of oil as compared with natural gas is significantly different from the energy equivalent of six to one, utilizing a boe conversion ratio of 6 Mcf:1 bbl or a Mcfe conversion ratio of 1 bbl:6 Mcf may be misleading as an indication of value.

Throughout this press release, "crude oil" or "oil" refers to light and medium crude oil product types as defined by National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). References to "NGLs" throughout this press release comprise pentane, butane, propane, and ethane, being all NGLs as defined by NI 51-101. References to "natural gas" throughout this press release refers to conventional natural gas as defined by NI 51-101.

Unit Cost Calculation. For the purpose of calculating unit costs, natural gas volumes have been converted to a boe using six thousand cubic feet equal to one barrel unless otherwise stated. A boe conversion ratio of 6:1 is based upon an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. This conversion conforms with National Instrument 51 101 - Standards of Disclosure for Oil and Gas Activities. Boe may be misleading, particularly if used in isolation.

Short-Term Results. References in this press release to IP30, production test rates, initial test production rates, and other short‐term production 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 Southern.  A pressure transient analysis or well test interpretation has not been carried out in respect of all wells.  Accordingly, the Company cautions that the test results should be considered to be preliminary.

Type Curves. Certain type curves disclosure presented herein represents estimates of the production decline and ultimate volumes expected to be recovered from wells over the life of the well. The type curves represent what management thinks an average well will achieve, based on methodology that is analogous to wells with similar geological features. 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 forward-looking statements contained in this press release are based on certain key expectations and assumptions made by Southern, including the timing of and success of future drilling, development and completion activities, the performance of existing wells, the performance of new wells, the availability and performance of drilling rigs, facilities and pipelines, the geological characteristics of Southern's properties, the characteristics of the Company's assets, the successful application of drilling, completion and seismic technology, benefits of current commodity pricing hedging arrangements, Southern's ability to enter into future derivative contracts on acceptable terms, Southern's ability to secure financing on acceptable terms, prevailing weather conditions, prevailing legislation affecting the oil and gas industry, prevailing commodity prices, price volatility, price differentials and the actual prices received for the Company's products, royalty regimes and exchange rates, impact of inflation on costs, the application of regulatory and licensing requirements, the Company's ability to obtain all requisite permits and licences, the availability of capital, labour and services, the creditworthiness of industry partners and the Company's ability to source and complete asset acquisitions.

Although Southern 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 Southern 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; the uncertainty of reserve estimates; the uncertainty of estimates and projections relating to production, costs and expenses, regulatory risks, and health, safety and environmental risks), constraint in the availability of services, negative effects of the current COVID-19 pandemic, commodity price and exchange rate fluctuations, geo-political risks, political and economic instability abroad, wars (including Russia's military actions in Ukraine), hostilities, civil insurrections, inflationary risks including potential increases to operating and capital costs,  changes in legislation impacting the oil and gas industry, adverse weather or break-up conditions and uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures. Ongoing military actions between Russia and the Ukraine have the potential to threaten the supply of oil and gas from the region. The long-term impacts of the actions between these nations remains uncertain. These and other risks are set out in more detail in Southern's MD&A and AIF.

The forward-looking information contained in this press release is made as of the date hereof and Southern undertakes no obligation to update publicly or revise any forward-looking information, whether as a result of new information, future events or otherwise, unless required by applicable securities laws. The forward-looking information contained in this press release is expressly qualified by this cautionary statement.

Future Oriented Financial Information. This press release contains future-oriented financial information and financial outlook information (collectively, "FOFI") about Southern's prospective results of operations, cash flow, increased capacity under the credit facility, capital expenditures and payout of wells, all of which are subject to the same assumptions, risk factors, limitations, and qualifications as set forth in the above paragraphs. FOFI contained in this document was approved by management as of the date of this document and was provided for the purpose of providing further information about Southern's future business operations. Southern and its management believe that FOFI has been prepared on a reasonable basis, reflecting management's best estimates and judgments, and represent, to the best of management's knowledge and opinion, the Company's expected course of action. However, because this information is highly subjective, it should not be relied on as necessarily indicative of future results. Southern disclaims any intention or obligation to update or revise any FOFI contained in this document, whether as a result of new information, future events or otherwise, unless required pursuant to applicable law. Readers are cautioned that the FOFI contained in this document should not be used for purposes other than for which it is disclosed herein. Changes in forecast commodity prices, differences in the timing of capital expenditures, and variances in average production estimates can have a significant impact on the key performance measures included in Southern's guidance. The Company's actual results may differ materially from these estimates.

Specified Financial Measures. This press release provides various financial measures that do not have a standardized meaning prescribed by IFRS, including non-IFRS financial measures, non-IFRS financial ratios and capital management measures. These specified financial measures may not be comparable to similar measures presented by other issuers. Southern's method of calculating these measures may differ from other companies and accordingly, they may not be comparable to measures used by other companies. Adjusted funds flow from operations, operating netback, adjusted working capital and net debt are not recognized measures under IFRS. Readers are cautioned that these specified financial measures should not be construed as alternatives to other measures of financial performance calculated in accordance with IFRS. These specified financial measures provide additional information that management believes is meaningful in describing the Company's operational performance, liquidity and capacity to fund capital expenditures and other activities. Please see below for a brief overview of all specified financial measures used in this release and refer to the Company's MD&A for additional information relating to specified financial measures, which is available on the Company's website at www.southernenergycorp.com and filed on SEDAR.

"Adjusted Funds Flow from Operations" (non-IFRS financial measure) is calculated based on cash flow from operative activities before changes in non-cash working capital and cash decommissioning expenditures. Management uses adjusted funds flow from operations as a key measure to assess the ability of the Company to finance operating activities, capital expenditures and debt repayments.  

"Adjusted Funds Flow from Operations per Share" (non-IFRS financial measure) is calculated by dividing Adjusted Funds Flow from Operations by the number of Southern shares issued and outstanding.

"Operating Netback" (non-IFRS financial measure) equals total oil and natural gas sales less royalties, production taxes, operating expenses, transportation costs and realized gain / (loss) on derivatives. Management considers operating netback an important measure to evaluate its operational performance, as it demonstrates field level profitability relative to current commodity prices.  

"Net Debt" (capital management measure) is monitored by Management, along with adjusted working capital, as part of its capital structure in order to fund current operations and future growth of the Company. Net debt is defined as long-term debt plus adjusted working capital surplus or deficit. Adjusted working capital is calculated as current assets less current liabilities, removing current derivative assets/liabilities, the current portion of bank debt, and the current portion of lease liabilities.  

 Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
