The evaluation process associated with these properties has not been completed and therefore, the Company is unable to estimate when these costs will be included in the depletion calculation. Results of operations of oil, NGL and natural gas producing activities The following table presents the results of operations of oil, NGL and natural gas producing activities (excluding corporate overhead and interest costs) for the periods presented: Years ended December 31, (in thousands) 2022 2021 2020 Revenues: Oil, NGL and natural gas sales $ 1,794,374 $ 1,147,143 $ 496,355 Production costs: Lease operating expenses 173,983 101,994 82,020 Production and ad valorem taxes 110,997 68,742 33,050 Transportation and marketing expenses 53,692 47,916 49,927 Total production costs 338,672 218,652 164,997 Other costs: Depletion 298,259 201,691 203,492 Accretion of asset retirement obligation 3,653 4,018 4,227 Impairment expense — — 889,453 Income tax expense (1) 11,538 14,456 — Total other costs 313,450 220,165 1,097,172 Results of operations $ 1,142,252 $ 708,326 $ (765,814) _____________________________________________________________________________ (1) During each of the years ended December 31, 2022, 2021 and 2020, the Company recorded valuation allowances against its deferred tax assets related to its oil, NGL and natural gas producing activities. Accordingly, the income tax expense was computed utilizing the Company's effective tax rate of 1% for the year ended December 31, 2022, 2% for the year ended December 31, 2021 and 0% for the year ended December 31, 2020, which reflects tax deductions and tax credits and allowances relating to the oil, NGL and natural gas producing activities that are reflected in the Company's "Total income tax (expense) benefit" on the consolidated statements of operations. Net proved oil, NGL and natural gas reserves Ryder Scott Company, L.P. ("Ryder Scott"), the Company's independent reserve engineers, estimated 100% of the Company's proved reserves as of December 31, 2022, 2021 and 2020. In accordance with SEC regulations, the reserves as of December 31, 2022, 2021 and 2020 were estimated using the Realized Prices, which reflect adjustments to the Benchmark Prices for quality, certain transportation fees, geographical differentials, marketing bonuses or deductions and other factors affecting the price received at the delivery point. See Note 6 for these Realized Prices. The Company's reserves are reported in three streams: oil, NGL and natural gas. The SEC has defined proved reserves as the estimated quantities of oil, NGL and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. The process of estimating oil, NGL and natural gas reserves is complex, requiring significant decisions in the evaluation of available geological, geophysical, engineering and economic data. The data for a given property may also change substantially over time as a result of numerous factors, including additional development activity, evolving production history and a continual reassessment of the viability of production under changing economic conditions. As a result, material revisions to existing reserve estimates occur from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the subjective decisions and variances in available data for various properties increase the likelihood of significant changes in these estimates. If such changes are material, they could significantly affect future amortization of capitalized costs and result in impairment of assets that may be material. The following tables provide an analysis of the changes in estimated proved reserve quantities of oil, NGL and natural gas for the years ended December 31, 2022, 2021 and 2020, all of which are located within the U.S.: Oil NGL Natural gas MBOE (1) Proved developed and undeveloped reserves: As of December 31, 2019 78,639 102,198 675,237 293,377 Revisions of previous estimates (10,517) 6,218 34,376 1,430 Extensions, discoveries and other additions 4,282 1,811 10,772 7,888 Acquisitions of reserves in place 5,182 1,310 6,948 7,650 Production (9,827) (10,615) (70,049) (32,117) As of December 31, 2020 67,759 100,922 657,284 278,228 Revisions of previous estimates 4,740 16,952 102,080 38,709 Extensions, discoveries and other additions 10,354 5,269 22,479 19,369 Acquisitions of reserves in place 65,572 19,711 90,023 100,286 Divestitures of reserves in place (15,904) (34,129) (228,546) (88,125) Production (11,619) (8,678) (57,175) (29,827) As of December 31, 2021 120,902 100,047 586,145 318,640 Revisions of previous estimates (9,792) (4,561) (14,694) (16,802) Extensions, discoveries and other additions 21,351 7,162 33,767 34,141 Divestitures of reserves in place (2,165) (808) (3,671) (3,585) Production (13,838) (8,028) (49,259) (30,076) As of December 31, 2022 116,458 93,812 552,288 302,318 Proved developed reserves: December 31, 2019 52,711 90,861 600,334 243,628 December 31, 2020 51,751 96,251 633,503 253,586 December 31, 2021 70,727 78,908 494,476 232,048 December 31, 2022 70,333 75,156 464,567 222,917 Proved undeveloped reserves: December 31, 2019 25,928 11,337 74,903 49,749 December 31, 2020 16,008 4,671 23,781 24,642 December 31, 2021 50,175 21,139 91,669 86,592 December 31, 2022 46,125 18,656 87,721 79,401 _____________________________________________________________________________ (1) BOE is calculated using a conversion rate of six Mcf per one Bbl. The following discussion is for the year ended December 31, 2022. The Company's negative revision of 16,802 MBOE of previously estimated quantities consisted of (i) 9,531 MBOE of negative revisions from performance of proved developed producing wells, (ii) 1,837 MBOE of negative revisions from a decrease in previously estimated quantities of proved undeveloped locations, (iii) 4,351 MBOE of positive revisions from an increase in the Realized Prices for oil, NGL and natural gas and other changes to proved wells and (iv) 9,785 MBOE of negative revisions due to 16 proved undeveloped locations that were removed from the development plan. Extensions, discoveries and other additions of 34,141 MBOE consisted of (i) 3,850 MBOE that resulted from new wells drilled and (ii) 30,291 MBOE that resulted from new horizontal proved undeveloped locations added in the Company's acreage in Howard and western Glasscock Counties. Sales of reserves of 3,585 MBOE attributed to the divestment of non-operated properties in Howard County. The following discussion is for the year ended December 31, 2021. The Company's positive revision of 38,709 MBOE of previously estimated quantities consisted of (i) 3,622 MBOE of negative revisions from performance of proved developed producing wells, (ii) 2,885 MBOE of negative revisions from a decrease in previously estimated quantities of proved undeveloped locations, (iii) 37,341 MBOE of positive revisions from an increase in the Realized Prices for oil, NGL and natural gas and other changes to proved wells and (iv) 7,875 MBOE of positive revisions due to proved undeveloped locations that were removed from the development plan in prior years. Six of these locations became proved developed producing wells in 2021 and twelve were revised back to proved undeveloped reserves as they became economically producible due to increased commodity prices and increases in lateral lengths. Extensions, discoveries and other additions of 19,369 MBOE consisted of (i) 6,724 MBOE that resulted from new wells drilled and (ii) 12,645 MBOE that resulted from new horizontal proved undeveloped locations added in the Company's acreage in Howard and western Glasscock Counties. Sales of reserves of 88,125 MBOE attributed to the divestment of 37.5% interest of certain proved developed producing wells in Reagan and Glasscock counties. Acquisitions of reserves in place of 100,286 MBOE consisted of (i) 47,310 MBOE from new proved developed wells (ii) 52,976 MBOE from new proved undeveloped locations in Howard and western Glasscock Counties. The following discussion is for the year ended December 31, 2020. The Company's positive revision of 1,430 MBOE of previously estimated quantities consisted of (i) 29,080 MBOE of positive revisions from performance of proved developed producing wells, (ii) 3,140 MBOE of negative revisions from a decrease in previously estimated quantities of proved undeveloped locations, (iii) 8,245 MBOE of negative revisions due to proved undeveloped locations that were removed due to year-end pricing and (iv) 16,265 MBOE of negative revisions from a decrease in the Realized Prices for oil, NGL and natural gas and other changes to proved wells. Extensions, discoveries and other additions of 7,888 MBOE consisted of (i) 5,347 MBOE that resulted from new wells drilled and (ii) 2,541 MBOE that resulted from new horizontal proved undeveloped locations added in the Company's Howard County, Texas acreage. Acquisitions of reserves in place of 7,650 MBOE consisted of (i) 367 MBOE from new proved developed producing wells and (ii) 4,016 MBOE from additional acreage acquired under proved locations in Howard County and (iii) 3,267 MBOE from new proved undeveloped locations in Howard County. Standardized measure of discounted future net cash flows The standardized measure of discounted future net cash flows does not purport to be, nor should it be interpreted to present, the fair value of the oil, NGL and natural gas reserves of the property. An estimate of fair value would take into account, among other things, the recovery of reserves not presently classified as proved, the value of proved properties and consideration of expected future economic and operating conditions. The estimates of future cash flows and future production and development costs as of December 31, 2022, 2021 and 2020 are based on the Realized Prices, which reflect adjustments to the Benchmark Prices for quality, certain transportation fees, geographical differentials, marketing bonuses or deductions and other factors affecting the price received at the delivery point. All Realized Prices are held flat over the forecast period for all reserve categories in calculating the discounted future net cash flows. Any effect from the Company's commodity hedges is excluded. In accordance with SEC regulations, the proved reserves were anticipated to be economically producible from the "as of date" forward based on existing economic conditions, including prices and costs at which economic producibility from a reservoir was determined. These costs, held flat over the forecast period, include development costs, operating costs, ad valorem and production taxes and abandonment costs after salvage. Future income tax expenses are computed using the appropriate year-end statutory tax rates applied to the future pretax net cash flows from proved oil, NGL and natural gas reserves, less the tax basis of the Company's oil and natural gas properties. The estimated future net cash flows are then discounted at a rate of 10%. The Company's unamortized cost of evaluated oil and natural gas properties being depleted exceeded the full cost ceiling for each of the quarterly periods in 2020 and, as such, the Company recorded non-cash full cost ceiling impairments totaling $889.5 million during the year ended December 31, 2020. No full cost ceiling impairment was recorded for the years ended December 31, 2022 and December 31, 2021. See Note 6 for discussion of the Benchmark Prices, Realized Prices and the 2020 full cost ceiling impairment recorded. The following table presents the standardized measure of discounted future net cash flows relating to proved oil, NGL and natural gas reserves for the periods presented: Years ended December 31, (in thousands) 2022 2021 2020 Future cash inflows $ 16,343,468 $ 11,846,148 $ 3,824,104 Future production costs (4,136,380) (3,595,524) (1,740,537) Future development costs (1,403,721) (1,064,527) (351,568) Future income tax expenses (1,587,677) (774,461) (20,076) Future net cash flows 9,215,690 6,411,636 1,711,923 10% discount for estimated timing of cash flows (4,461,114) (2,986,324) (697,069) Standardized measure of discounted future net cash flows $ 4,754,576 $ 3,425,312 $ 1,014,854 It is not intended that the FASB's standardized measure of discounted future net cash flows represent the fair market value of the Company's proved reserves. The Company cautions that the disclosures shown are based on estimates of proved reserve quantities and future production schedules which are inherently imprecise and subject to revision, and the 10% discount rate is arbitrary. In addition, prices and costs as of the measurement date are used in the determinations, and no value may be assigned to probable or possible reserves. The following table presents the changes in the standardized measure of discounted future net cash flows relating to proved oil, NGL and natural gas reserves for the periods presented: Years ended December 31, (in thousands) 2022 2021 2020 Standardized measure of discounted future net cash flows, beginning of year $ 3,425,312 $ 1,014,854 $ 1,662,261 Changes in the year resulting from: Sales, less production costs (1,468,946) (934,440) (331,358) Revisions of previous quantity estimates (99,512) 426,060 199 Extensions, discoveries and other additions 667,859 293,511 60,004 Net change in prices and production costs 2,565,963 1,572,662 (770,885) Changes in estimated future development costs (165,579) 134,091 64,146 Previously estimated development incurred capital expenditures during the period 260,475 169,376 186,261 Acquisitions of reserves in place — 1,509,087 14,208 Divestitures of reserves in place (96,222) (369,601) — Accretion of discount 371,625 102,607 167,227 Net change in income taxes (418,537) (279,722) (1,205) Timing differences and other (287,862) (213,173) (36,004) Standardized measure of discounted future net cash flows, end of year $ 4,754,576 $ 3,425,312 $ 1,014,854 Estimates of economically recoverable oil, NGL and natural gas reserves and of future net cash flows are based upon a number of variable factors and assumptions, all of which are, to some degree, subjective and may vary considerably from actual results. Therefore, actual production, revenues, development and operating expenditures may not occur as estimated. The reserve data are estimates only, are subject to many uncertainties and are based on data gained from production histories and on assumptions as to geologic formations and other matters. Actual quantities of oil, NGL and natural gas may differ materially from the amounts estimated. |
