Executive Summary

An engineering and economic evaluation was prepared for oil and gas reserves located in the Williston Basin Sanish Field in Mountrail County, North Dakota in which Energy 11, LP owns a working and/or royalty interest. The oil and gas reserves associated with these properties were evaluated and classified as Proved Reserves in accordance with the definitions and regulations of the U.S. Securities and Exchange Commission (SEC). The Proved reserves include two hundred thirty-two (232) horizontal Proved Developed Producing (PDP) wells, sixteen (16) horizontal Proved Developed Non-Producing (PDNP) wells and sixty (60) Proved Undeveloped (PUD) horizontal locations targeting the Bakken Shale and Three Forks formation in multiple sections/units. Also included in the attached economic reports is one (1) Proved Developed Shut-In (PDSI) well; however, this well was given no value or reserves for this evaluation. Remaining reserves, future cashflow, and present worth values were calculated as of January 1, 2020. It is our understanding that the proved reserves estimated in this report constitute all of the proved reserves owned by Energy 11.

The reserves and economics were determined using SEC YE2019 pricing as of January 1, 2020. Table 1 summarizes the estimated net reserves and future net revenue (cashflow), discounted and undiscounted, to the Energy 11 interest in these properties.

Economic Evaluation

Future Income

Future net revenue in this report includes deductions for state production taxes. Future net cashflow is after deducting state production taxes, future capital investments, and lease operating expenses but before consideration of any state and/or federal income taxes. For purposes of this evaluation, future capital investments include costs for drilling, completing, and equipping new wells. Abandonment costs of 100 M$ at the end of well life for each well have been included in this evaluation. The future net cashflow has not been adjusted for any outstanding loans that may exist, cash on hand, or undistributed income. Future net cashflow has been discounted at an annual rate of ten percent (10%) to determine its “present worth.” The present worth is shown to indicate the effect of time on the value of money. Future net revenue (cashflow) presented in this report, whether discounted or undiscounted, should not be construed as being the fair market value of the properties evaluated.

Interests

Well and leasehold interests were provided by Energy 11 and are shown in Exhibit A. The non-operated interests average approximately 25% working interest and 20% net revenue interest.

Product Pricing

Per SEC rules, the SEC pricing is determined by calculating the unweighted arithmetic average of the first-day-of-the-month NYMEX oil and gas pricing for the prior twelve calendar months (January 2019 through December 2019) to the date of evaluation. All prices are held constant throughout the lives of the properties. For year-end 2019, the unweighted arithmetic average NYMEX (Cushing) oil price is 55.69 $/bbl and the average NYMEX (Henry Hub) natural gas price is 2.58 $/MMbtu. Prices were adjusted for quality, basis, energy content, transportation fees and other market differentials based on an analysis of revenue data.

Differentials to NYMEX pricing were calculated by examining revenue statements and financial information to determine deductions or increases to oil and gas prices due to Btu, differentials, NGLs, processing, transportation, and/or contract terms. The pricing adjustments and differentials by operator are shown in Table 3.

Including the adjustments for quality, basis, energy content, transportation fees and other market differentials, the average realized prices held constant throughout the lives of the properties were 47.70 $/bbl oil, -0.03 $/Mcf natural gas and 8.91 $/bbl NGL.

Expenses

An expense model, based on actual costs and the age of each individual well, was provided by Energy 11 to model the actual well life expense changes for all wells and undeveloped locations. Expenses were not escalated.

Future Well Investments

Capital expenses for the future locations were estimated to be 7,600 M$/well, which is consistent with recent, actual industry drilling and completion costs for wells within the prospective area. Capital expenses for installation of an electric submersible pump (ESP) of 200 M$/well was also included at a cumulative production of 85 MBO for each future location. Capital timing for future development work was provided by Energy 11. Pinnacle cannot be responsible for capital costs that exceed or are less than these estimates.

PDP production has been reduced by 10% of the forecasted volumes for 24 months after the effective date to account for expected temporary downtime during completion and stimulation of offset future well locations. These reserves are modeled to be recovered throughout the life of the wells.

Reserve Determination

RESERVE DISCUSSION

Remaining recoverable reserves are those quantities of petroleum which are anticipated to be commercially recovered from known accumulations from a given date forward. All reserve estimates involve some degree of uncertainty depending primarily on the amount of reliable geologic and engineering (production, pressure) data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty is conveyed by classifying reserves as Proved (highly certain) or Non-Proved (less certain). The estimated reserves and revenues shown in this report were determined by SEC standards for Proved Developed Producing (PDP) wells, Proved Developed Non-Producing (PDNP), and Proved Undeveloped (PUD) locations.   

Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs with defined limits and under current economic conditions, operating methods, and government regulations. Changes in any of these variables could materially change the reserves actually recovered.

Proved reserves are further classified as Proved Developed Producing (PDP) which is assigned to wells with sufficient production history to allow material balance and decline curve analysis to be the primary methods of estimation. PDP reserves are the most reliable reserves, generally with a high degree of confidence (>90%) that actually recovered quantities will equal or exceed published reserve estimates.

Proved Developed Non-Producing (PDNP) reserves include zones that have been penetrated by drilling but have not produced or have not produced in sufficient quantities to allow material balance or decline curve analysis with a high degree of confidence. This category includes wells awaiting completion.

Proved Undeveloped (PUD) reserves are those quantities of petroleum that are estimated to be recovered from undrilled acreage (locations) in a continuous portion of the Proved Developed reservoir as defined by directly offsetting Proved Developed (PDP) wells and geological interpretations. The Proved Undeveloped wells are forecasted based on geological data presented, volumetric calculations, and analog comparisons to existing completions.

General

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. When possible and practical, volumetric calculations and analogies were integrated into the reserve estimates. As additional pressure and production performance data becomes available, reserve estimates may increase or decrease in the future. The revenue from such reserves and the actual costs related may be more or less than the estimated amounts. 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. We consider all assumptions, data, and procedures utilized in this report appropriate for the purpose of this report.

In evaluating the information available for this analysis, items excluded from consideration were all matters as to which legal or accounting interpretation, 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.
