Standardized Measure of Discounted Future Net Cash Flows from Proved Reserves
As required by the FASB and SEC, the standardized measure of discounted future net cash flows presented below is computed by applying first-day-of-the-month average prices, year-end costs and legislated tax rates and a discount factor of 10 percent to proved reserves. We do not believe the standardized measure provides a reliable estimate of the Company’s expected future cash flows to be obtained from the development and production of its oil and gas properties or of the value of its proved oil and gas reserves. The standardized measure is prepared on the basis of certain prescribed assumptions including first-day-of-the-month average prices, which represent discrete points in time and therefore may cause significant variability in cash flows from year to year as prices change.
Oil and Natural Gas Reserves
Users of this information should be aware that the process of estimating quantities of “proved” and “proved developed” oil and natural gas reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a given reservoir may also change substantially over time as a result of numerous factors including, but not limited to, additional development activity, evolving production history and continual reassessment of the viability of production under varying economic conditions. As a result, revisions to existing reserve estimates may occur from time to time. Although every reasonable effort is made to ensure reserve estimates reported represent the most accurate assessments possible, the subjective decisions and variances in available data for various reservoirs make these estimates generally less precise than other estimates included in the financial statement disclosures.
Proved reserves are those quantities of oil and natural gas that by analysis of geoscience and engineering data can be estimated with reasonable certainty to be economically producible — from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations — prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.
We engaged Cawley, Gillespie and Associates (“CG&A”) to prepare our reserves estimates for all of our estimated proved reserves (by volume) at December 31, 2019. All proved reserves are located in the United States and all prices are held constant in accordance with SEC rules.
The weighted-average benchmark product prices used for valuing the reserves are based upon the average of the first-day-of-the-month price for each month within the period January through December of each year presented:

Noteworthy amounts included in the categories of proved reserve changes in the above tables include:
|
• |
The 22.8 MMBoe increase in reserves for the year ended December 31, 2019 is primarily due to the Merger in which we acquired 69.7 MMBoe partially offset by downward pricing revision of a 25.9 MMBoe and a downward revision of 12.1 MMBoe due to updated well performance data and future anticipated maintenance cost increases. |
|
• |
The 24.7 MMBoe reduction in reserves for the year ended December 31, 2018 is primarily due to a 4.6 MMBoe upward pricing revision and a 10.6 MMBoe downward revision due to updated well performance data and future anticipated development and maintenance cost increases. We divested 11.0 MMBoe during the year ended December 31, 2018. We added 1.9 MMBoe during the year ended December 31, 2018 due to extensions and discoveries. |
|
• |
The 16.5 MMBoe reduction in reserves for the period from May 5, 2017 through December 31, 2017 is primarily due to a 2.2 MMBoe upward pricing revision and a 12.8 MMBoe downward revision due to updated well performance data and future anticipated development and maintenance cost increases. We added 1.2 MMBoe during the period from May 5, 2017 through December 31, 2017 due to extensions and discoveries. |
|
• |
The 28.7 MMBoe increase in reserves for the January 1, 2017 through May 4, 2017 is primarily due to a 34.1 MMBoe upward pricing revision and a 1.5 MMBoe downward revision due to updated well performance data. Proved undeveloped reserves increased primarily due to upward pricing during the period from January 1, 2017 through May 4, 2017. |
See Note 6 for additional information on acquisitions and divestitures.
A variety of methodologies are used to determine our proved reserve estimates. The principal methodologies employed are reservoir simulation, decline curve analysis, volumetric, material balance, advance production type curve matching, petro-physics/log analysis and analogy. Some combination of these methods is used to determine reserve estimates in substantially all of our fields.
