Re: USEG 4Q 2023 Reserve Report “as of” 1/1/24

Dear Ryan:

As per your request, I have evaluated remaining reserves for 249 properties in Kansas, Louisiana, Mississippi, Montana, North Dakota, New Mexico, Oklahoma, Texas, and Wyoming. Production was updated for all the leases and reserve projections were reviewed and revised. Operating expenses and price differentials were determined from your accounting system for all leases. This report is organized by USEG Districts. This report uses the SEC 4Q23 first day of the month price forecast averaged over the prior 12 months as confirmed by industry websites and documented in attachment 06. A summary table with each well’s value along with other reports are included in support of this 4Q23 evaluation.

Monthly production was updated through 11/31/23 for operated leases. A rigorous analysis of OPEX was done for the operated leases. OPEX was forecast with fixed costs determined from USEG accounting data from 1/22 through 10/23 for this 4Q23 report. Consistent with prior reports, abandonment and salvage costs were not applied so they can be handled separately and accounted for as a line item. Asset retirement obligations (ARO) are handled by USEG management.

Proved Developed Oil and Gas reserves, as shown in the E-mailed reports, are reserves that geological and engineering data indicate to be recoverable from known oil and gas reservoirs through existing wells with existing operating methods. The reserves in this report have been estimated using deterministic methods. These estimates have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (“SPE Reserves Standards”), revised June 2019 and distributed by SPE.

The reserves and values included in this report are estimates only and should not be construed as being exact quantities. The reserve estimates were performed using accepted engineering practices and were primarily based on historical rate decline analysis for existing producers. The reserve volumes were estimated based on the definitions and disclosure guidelines published by the Society of Petroleum engineers (SPE), Society of Petroleum Evaluations Engineers (SPEE), and Petroleum Reserves Management System (PRMS). Because of governmental policies and uncertainties of supply and demand, the prices actually received for the reserves included in this report and the costs incurred in recovering such reserves may vary from the price and cost assumptions referenced. Therefore, in all cases, estimates of reserves may increase or decrease as a result of future operations.

In evaluating the information available for this analysis, items excluded from consideration were all matters as to which legal or accounting, rather than engineering interpretation, may be controlling. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering data and such conclusions necessarily represent only informed professional judgments.

The title to the property has not been examined nor has the actual degree or type of interest owned been independently confirmed. A field inspection of the properties is not usually considered necessary for the purpose of this report.

Information included in this report includes the graphical decline curves, historical and projected production and cash flow economic results, and miscellaneous individual well information. Additional information reviewed will be retained and is available for review at any time. I can take no responsibility for the accuracy of the data used in the analysis, whether gathered from public sources or otherwise.

Sincerely,

Don Jacks
