Business and Organization | Note 1 – Business and Organization Roan Resources LLC (the “Company” or “Roan”) was formed in May 2017 to engage in the acquisition, exploration, development, production, and sale of oil and natural gas reserves. The Company’s oil and natural gas properties are located in Central Oklahoma. The Company’s corporate headquarters is located in Oklahoma City, Oklahoma. On August 31, 2017, the Companyexecuted a contribution agreement (the “Contribution Agreement”) by and among the Company, Citizen Energy II, LLC (“Citizen”), Linn Energy Holdings, LLC (“LEH”) and Linn Operating, LLC (“LOI”, and together with LEH, “Linn”) pursuant to which, among other things, Citizen and Linn agreed to contribute oil and natural gas properties within an area-of-mutual-interest The contributions of oil and natural gas properties to Roan by Citizen and Linn were determined to meet the definition of a business. However, as Roan had no assets or operations prior to the Contribution, it was determined that Citizen was the acquirer for accounting purposes in accordance with ASC Topic 805, Business Combinations (“ASC 805”) Note 4 – Acquisitions In conjunction with the Contribution Agreement, the Company entered into master services agreements with both Citizen and Linn (“MSAs”). Under the MSAs, Citizen and Linn provided certain services in respect to the oil and natural gas properties they contributed to the Company. Such services included serving as operator of the oil and natural gas properties contributed, land administration, marketing, information technology and accounting services. As a result of Citizen and Linn continuing to serve as operator of the contributed assets and contracting directly with vendors for goods and services for operations, Citizen and Linn collected amounts due from joint interest owners for their share of costs and billed the Company for its share of costs. The services provided under the MSAs ended in April 2018 when the Company took over as operator for the oil and natural gas properties contributed by Citizen and Linn. See Note 12 – Transactions with Affiliates | Note 1 – Business and Organization Roan Resources LLC (the “Company” or “Roan”) is a Delaware Limited Liability Company formed on May 30, 2017, to engage in the acquisition, development, production, exploration and sale of oil and natural gas reserves.

Accounting Policies [Abstract] | |
Basis of Presentation and Significant Accounting Policies | Note 2 – Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying financial statements were prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Use of Estimates The preparation of financial statements and related footnotes in conformity with GAAP requires that management formulate estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent assets and liabilities. A significant item that requires management’s estimates and assumptions is the estimate of proved oil, natural gas and natural gas liquid (“NGLs”) reserves which are used in the calculation of depletion of the Company’s oil and natural gas properties and impairment, if any, of proved oil and natural gas properties. Changes in estimated quantities of its reserves could impact the Company’s reported financial results as well as disclosures regarding the quantities and value of proved oil and natural gas reserves. Although management believes these estimates are reasonable, actual results could differ from these estimates. Revenue Recognition Revenues from the sale of oil, natural gas and NGLs are recognized when the product is delivered at a fixed or determinable price, title has transferred and collectability is reasonably assured. The Company recognizes revenues from the sale of oil, natural gas and NGLs using the sales method, whereby revenue is recorded based on the Company’s share of volumes sold. If the Company’s aggregate sales volumes for a well are greater (or less) than its proportionate share of production from the well, a liability (or receivable) is established to the extent there are insufficient proved reserves available to make up the overproduced (or under produced) imbalance. There were no material imbalances at December 31, 2017 or 2016. Business Combinations The Company accounts for all business combinations using the acquisition method, which involves the use of significant judgment. In a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is recorded as a gain on bargain purchase or goodwill. The Company estimates the fair values of assets acquired and liabilities assumed in a business combination using various assumptions (all of which are Level 3 inputs within the fair value hierarchy). The most significant assumptions typically relate to the estimated fair values assigned to proved and unproved oil and natural gas properties. To estimate the fair values of the proved and unproved oil and natural gas properties, the Company develops estimates of oil, natural gas and NGL reserves. Estimates of reserves are based on the quantities of oil, natural gas and NGLs that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under existing economic and operating conditions. Additionally, a risk factor is applied to reserves by reserve type based on industry standards. The Company estimates future prices to apply to the estimated net quantities of reserves based on the applicable ownership percentage acquired and estimates future operating and development costs to arrive at estimates of future net cash flows. The future net cash flows are discounted using a market-based weighted average cost of capital rate determined appropriate at the time of the acquisition. Oil and Natural Gas Properties The Company follows the successful efforts method to account for its exploration and production activities. Under this method, costs incurred to purchase, lease, or otherwise acquire a property, whether unproved or proved, are capitalized when incurred. The Company initially capitalizes exploratory well costs pending a determination whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Other exploration costs, including geological and geophysical costs, delay rentals and administrative costs associated with unproved property and unsuccessful exploratory well costs are expensed as incurred. Additionally, costs to operate and maintain wells and field equipment are expensed as incurred. Depletion is computed on a units-of-production unit-of-production Unproved properties and the related costs are transferred to proved properties when reserves are discovered on, or otherwise attributed, to the property. The net carrying values of retired, sold or abandoned proved properties that constitute less than a complete unit of depletable property are charged, net of proceeds, to accumulate depreciation, depletion and amortization unless doing so significantly affect the unit-of-production Proceeds from sales of all or a partial interest in individual unproved properties assessed for impairment on a group basis are accounted for as a recovery of costs. No gain or loss is recognized unless the sales proceeds exceed the original cost of the entire interest in the property, in which a gain will be recognized for the excess. Impairment of Oil and Natural Gas Properties Proved oil and natural gas properties are evaluated for impairment annually or when facts or circumstances indicate that the carrying value of those assets may not be recoverable, such as when there are declines in oil and natural gas prices or well performance. In performing this assessment, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. An impairment loss is indicated if the sum of the estimated undiscounted future cash flows related to an asset group is less than the carrying value of that asset group. If an impairment loss has been incurred, the loss recognized is the excess of the carrying amount over the estimated fair value. The Company calculates the estimated fair value using a discounted future cash flow model. Management’s assumptions associated with the calculation of future cash flows include oil and natural gas prices based on NYMEX futures price strips, as well as other assumptions, including (i) pricing adjustments for differentials, (ii) production costs, (iii) capital expenditures, (iv) production volumes, (v) timing of development, and (vi) estimated reserves. A discount rate, consistent with that used by market participants, is applied to the estimated future cash flows in order to estimate fair value. Cash flow estimates for impairment testing exclude the effects of derivative instruments. It is reasonably possible that the estimate of undiscounted future net cash flows may change in the future resulting in the need to impair carrying values. The primary factors that may affect estimates of future cash flows are (i) oil and natural gas futures prices, (ii) increases or decreases in production and capital costs, (iii) future reserve adjustments, both positive and negative, to proved reserves and appropriate risk-adjusted probable and possible reserves, and (iv) results of future drilling activities. The Company’s unproved properties are assessed for impairment annually, or more frequently if events or changes in circumstances dictated that the carrying value of those assets may not be recoverable. Unproved leasehold costs are amortized on a group basis if individually insignificant, and a valuation allowance is established with a monthly amortization charge to exploration expense for the portion of the properties’ total cost that management estimates may never be transferred to proved properties during the lives of the respective leases. The impairment amortization rate considers the Company’s current drilling plans, the remaining terms of the respective leases and the results of exploratory drilling activity, and can be affected by economic factors including oil and natural gas price outlooks, projected capital costs, and available liquidity. Costs of expired or relinquished leases are charged against the valuation allowance. Drilling Advances The Company’s drilling advances consist of cash provided to the Company from its joint interest partners for planned drilling activities. Advances are applied against the joint interest partner’s share of expenses incurred. As noted above, the Company entered into MSAs with Citizen and Linn to perform services, including operating the contributed assets. Any drilling advances due to or from other joint interest owners are maintained by Citizen and Linn. See Note 12 – Transactions with Affiliates Asset Retirement Obligation The Company is obligated to fund the costs of disposing of long-lived assets upon their abandonment. The Company’s asset retirement obligations (“ARO”) relate to the plugging of wells and the related abandonment of oil and natural gas properties. AROs are recognized as liabilities with an increase to the carrying amounts of the related assets when the obligation is incurred. The cost of the asset, including ARO, is depreciated over the useful life of the asset. Fair value of ARO is measured using the expected future cash outflows required to satisfy the retirement obligations discounted at the Company’s credit-adjusted risk-free interest rate. Accretion expense is recognized over time as the discounted liabilities are accreted to their expected settlement value and the liability is settled or the well is sold, at which time the liability is removed. Accretion expense is included in accretion expense in the accompany statements of operations. Derivative Instruments The Company has entered into commodity derivative instruments to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. The commodity derivative instruments are measured at fair value and are included in the balance sheet as derivative assets and derivative liabilities, on a net basis by counterparty. The Company has not designated any of the derivative contracts as fair value or cash flow hedges for accounting purposes for any of the periods presented. Accordingly, net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments and are included in loss on derivative contracts in the accompanying statements of operations. The Company’s cash flow is impacted when the settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty and are reflected as operating activities in the Company’s statements of cash flows. The Company’s firm sales contracts qualify for the normal purchase and normal sale exception. Contracts that qualify for this treatment do not require mark-to-market Cash and Cash Equivalents The Company maintains its cash balances at credit-worthy financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). At times, cash balances may be in excess of FDIC limits. The Company has not incurred any losses related to the amounts in excess of FDIC limits. Accounts Receivable Accounts receivable consists mainly of receivables from oil, natural gas and NGL purchasers and joint interest owners on properties the Company operates. Accounts receivable from the sale of oil, natural gas and NGLs are accrued based on estimates of the volumetric sales and prices the Company believes it will receive. The Company routinely reviews outstanding balances, assesses the financial strength of its purchasers and joint interest owners and records a reserve for amounts not expected to be fully recovered. The need for an allowance is determined based upon reviews of individual accounts, existing economic conditions and other pertinent factors. No bad debt expense was recorded for the years ended December 31, 2017, 2016 or 2015 and the Company had no reserve for bad debts at December 31, 2017 or 2016. Deferred Financing Costs Costs incurred in connection with the Company’s debt are capitalized and amortized as interest expense over the scheduled maturity period. Unamortized costs are associated with the Company’s revolving credit facility and are reflected as a component of long-term assets on the accompanying balance sheets. Equity-Based Compensation In December 2017, the Company granted certain employees performance share units (“PSUs”) pursuant to the Roan Resources LLC Management Incentive Plan (the “Plan”). PSUs issued under this Plan were recognized as equity awards based on their characteristics. The compensation measurement was based on the grant date fair value of the award. Equity compensation is recognized over the requisite service period. For employees directly involved in exploration and development activities, equity compensation is capitalized to the Company’s oil and natural gas properties. Equity compensation not capitalized is recognized in general and administrative expenses or production expense in the statements of operations. Comprehensive Income The Company has no elements of comprehensive income other than net income. Concentrations of Credit Risk The Company sells oil, natural gas and NGLs to various types of customers. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside the Company’s control, none of which can be predicted with certainty. Additionally, limitations on capacity at processing plants could also impact the Company’s ability to sell its oil, natural gas and NGLs. The Company is subject to credit risk resulting from the concentration of its oil, natural gas and NGL receivables with two significant purchasers. The Company does not believe the loss of any single purchaser would materially impact its results of operations because oil, natural gas and NGLs are fungible products with well-established markets and numerous purchasers. For the years ended December 31, 2017, 2016, and 2015, the Company had the following major customers that exceeded 10% of total oil, natural gas and NGL revenues: Year Ended 2017 2016 2015 Sunoco Inc. 40 % 55 % 61 % EnLink Oklahoma Gas Processing, LP 39 % 31 % * Cimarex Energy Company * * 14 % * Revenue from customer was less than 10% in this year The Company’s derivative transactions have been carried out in the over-the-counter over-the-counter Fair Value Measurements The Company follows a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: Level 1— Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Level 2— Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1 that are either directly or indirectly observable as of the reporting date. Level 3— Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value. Reclassifications of fair value between Level 1, Level 2 and Level 3 of the fair value hierarchy, if applicable, are made at the end of each quarter. There were no transfers between levels during 2017 or 2016. The carrying values of the Company’s receivables, payables and long-term debt are estimated to be substantially the same as their fair values at December 31, 2017 and 2016. As noted above, the Company carries its derivative financial instruments at fair value. Commitments and Contingencies The Company is subject to legal proceedings, claims, and liabilities that arise in the ordinary course of business. An accrual is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based on the anticipated most likely outcome or the minimum amount within a range of possible outcomes. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. The amount of ultimate loss may differ from these estimates. Except for environmental contingencies acquired in a business combination, which are recorded at fair value, the Company accrues losses associated with environmental obligations when such losses are probable and can be reasonably estimated. Earnings per Unit The Company uses the treasury stock method to determine the potential dilutive effect of outstanding performance share units. Refer to Note 11 – Performance Share Units Income Taxes The Company is organized as a Delaware limited liability company. The Company is treated as a flow-through entity for income tax purposes. As a result, the net taxable income or loss of the Company and any related tax credits, for federal income tax purposes, are deemed to pass to the members and are included in the Company’s tax returns even though such net taxable income or loss and tax credits may not have actually been distributed. Accordingly, no tax provision has been made in the financial statements of the Company since the income tax is an obligation of the members. Risks and Uncertainties Historically, the markets for oil, natural gas, and NGLs have experienced significant price fluctuations. Price fluctuations can result from variations in weather, regional levels of production, availability of transportation capacity, and various other factors. Increases or decreases in the prices the Company receives for its production could have a significant impact on the Company’s future results of operations and reserve quantities. A portion of the Company’s oil and natural gas production may be interrupted, or shut in, from time to time for various reasons, including, but not limited to, as a result of accidents, weather conditions, the unavailability of gathering, processing, compression, transportation or refining facilities or equipment or field labor issues, or intentionally as a result of market conditions such as oil or natural gas prices that the Company deems uneconomic. If a substantial amount of the Company’s production is interrupted or shut in, the Company’s cash flows and, in turn, it’s financial condition and results of operations could be materially and adversely affected. |

Derivative Instruments | Note 8 – Derivative Instruments The Company utilizes fixed price swaps and basis swaps to manage the price risk associated with forecasted sale of its oil and natural gas production. Fixed price swaps are settled monthly based on differences between the fixed price specified in the contract and the referenced settlement price. Basis swaps are settled monthly based on differences between a fixed price differential and the applicable market price differential. When the referenced settlement price is less than the price specified in the contract, the Company receives an amount from the counterparty based on the price difference multiplied by the volume. Similarly, when the referenced settlement price exceeds the price specified in the contract, the Company pays the counterparty an amount based on the price difference multiplied by the volume.

Fair Value Measurements | Note 9 – Fair Value Measurements The Company measures and reports certain assets and liabilities on a fair value basis and has classified and disclosed its fair value measurements using the following levels of the fair value hierarchy: Level 1— Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Level 2— Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1 that are either directly or indirectly observable as of the reporting date. Level 3— Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value. Assets and liabilities that are measured at fair value are classified based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values, stated below, considers the market for the Company’s financial assets and liabilities, the associated credit risk and other factors. The Company considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis. The Company recognizes transfers between fair value hierarchy levels as of the end of the reporting period in which the event or change in circumstances causing the transfer occurred. During the six months ended June 30, 2018, the Company did not have any transfers between Level 1, Level 2 or Level 3 fair value measurements. Assets and Liabilities Measured at Fair Value on a Recurring Basis The Company’s recurring fair value measurements are performed for its commodity derivatives. Commodity Derivative Instruments Commodity derivative contracts are stated at fair value in the accompanying balance sheets. The Company adjusts the valuations from the valuation model for nonperformance risk and for counterparty risk. The fair values of the Company’s commodity derivative instruments are classified as Level 2 measurements as they are calculated using industry standard models using assumptions and inputs which are substantially observable in active markets throughout the full term of the instruments. These include market price curves, contract terms and prices, credit risk adjustments, implied market volatility and discount factors. The following table presents the amounts and classifications of the Company’s derivative assets and liabilities as of June 30, 2018 and December 31, 2017, as well as the potential effect of netting arrangements on contracts with the same counterparty (in thousands): June 30, 2018 Level 1 Level 2 Level 3 Gross Fair Netting Carrying Assets Current commodity derivatives $ — $ 3,208 $ — $ 3,208 $ (2,927 ) $ 281 Long-term commodity derivatives — 2,064 — 2,064 (2,064 ) — Total assets $ — $ 5,272 $ — $ 5,272 $ (4,991 ) $ 281 Liabilities Current commodity derivatives $ — $ (52,351 ) $ — $ (52,351 ) $ 2,927 $ (49,424 ) Long-term commodity derivatives — (12,728 ) — (12,728 ) 2,064 (10,664 ) Total liabilities $ — $ (65,079 ) $ — $ (65,079 ) $ 4,991 $ (60,088 ) December 31, 2017 Level 1 Level 2 Level 3 Gross Fair Netting Carrying Assets Current commodity derivatives $ — $ 2,856 $ — $ 2,856 $ (2,704 ) $ 152 Long-term commodity derivatives — 2,182 — 2,182 (1,186 ) 996 Total assets $ — $ 5,038 $ — $ 5,038 $ (3,890 ) $ 1,148 Liabilities Current commodity derivatives $ — $ (11,983 ) $ — $ (11,983 ) $ 2,704 $ (9,279 ) Long-term commodity derivatives — (2,557 ) — (2,557 ) 1,186 (1,371 ) Total liabilities $ — $ (14,540 ) $ — $ (14,540 ) $ 3,890 $ (10,650 ) Non-Recurring The Company’s non-recurring discounted-cash non-recurring Note 4 — Acquisitions Note 11 Performance Share Units Other Financial Instruments The Company’s financial instruments, not otherwise recorded at fair value, consist primarily of cash, trade receivables, trade payables, and long-term debt. The carrying values of cash and cash equivalents, accounts payable, revenue payable, and accounts receivable approximate fair values due to the short-term maturities of these instruments and the carrying value of long-term debt approximates fair value as the applicable interest rates are variable and reflective of market rates. | Note 9 – Fair Value Measurements Assets and liabilities that are measured at fair value are classified based on the lowest level of input that is significant to the fair value measurement.

These assets and liabilities are not measured at fair value on a recurring basis, but are subject to fair value adjustments when facts are circumstances arise that indicate a need for measurement. The Company utilizes fair value on a non recurring basis to review its proved oil and natural gas properties for potential impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of such property. The Company uses an income approach analysis based on management’s estimated net discounted future cash flows of proved property. Unobservable inputs included estimates of oil and natural gas production, as the case may be, from the Company’s reserve reports, commodity prices based on the sales contract terms or forward price curves, operating and development costs, and a discount rate based on a market-based weighted average cost of capital (all of which are Level 3 inputs within the fair value hierarchy).

Performance Share Units | Note 11 – Performance Share Units The Company has adopted an equity-based compensation plan (“the Plan”), which provides for future grants of options, unit appreciation rights, restricted units, phantom units, unit awards, performance awards and other unit-based awards. The Company has reserved 105 million Units for delivery with respect to these awards. The Company grants performance share units (“PSUs”) pursuant to the terms of the Plan and individual performance share unit agreements. The percent of awarded PSUs in which each recipient vests, if any, will range from 0% to 200% based on the Company’s value on December 31, 2020 (“Performance Period End Date”). The Company’s value on the Performance Period End Date will be determined by (a) if prior to an initial public offering, the value of the Company determined in good faith by a designated committee of the Board of Managers of the Company, or (b) if on or following an initial public offering, the market value of the public entity determined with reference to the volume-weighted average price of the publicly traded securities of the public entity for the 30 consecutive trading days immediately preceding the Performance Period End Date, as reported on the stock exchange composite tape. Each vested PSU is exchangeable for one Unit of the Company. The following table summarizes information related to the total number of PSUs awarded as of June 30, 2018: Number of Weighted Total Fair Units outstanding at December 31, 2017 16,350,000 $ 1.41 $ 23,054 Units granted 6,325,000 $ 2.05 $ 12,966 Units vested — $ — $ — Units outstanding at June 30, 2018 22,675,000 $ 1.59 $ 36,020 Compensation expense associated with the PSU awards for the six months ended June 30, 2018 was $5.1 million and is included in general and administrative expenses on the accompany statement of operations. Unrecognized expense as of June 30, 2018 for all outstanding PSU awards was $30.6 million and will be recognized over a weighted-average remaining period of 2.50 years. The grant date fair value of the PSUs was determined using a Monte Carlo simulation model, which results in an estimated percentage of performance share units earned and estimated Company value on the Performance Period End Date. The grant date fair value of the PSUs is expensed on a straight-line basis from the grant date to the Performance Period End Date. The following assumptions were used for the Monte Carlo simulation model to determine the grant date fair value and associated compensation expense for the PSU awards granted during the six months ended June 30, 2018: Company enterprise value $ 4.56 billion Equity volatility 34.0 % Weighted average risk-free interest rate 1.96 % | Note 11 – Performance Share Units The Company has adopted the Plan, which provides for future grants of options, unit appreciation rights, restricted units, phantom units, unit awards, performance awards and other unit-based awards. The Company has reserved 105 million Units for delivery with respect to these awards. During December 2017, Roan made grants of approximately16.4 million PSUs pursuant to the terms of the Plan and individual Performance Share Unit Agreements. The percent of awarded PSUs in which each recipient vests, if any, will range from 0% to 200% based on the Company’s value on December 31, 2020 (“Performance Period End Date”). The Company’s value on the Performance Period End Date will be determined by (a) if prior to an initial public offering, the value of the Company determined in good faith by a designated committee of the Board of Managers of the Company, or (b) if on or following an initial public offering, the market value of the public entity determined with reference to the volume-weighted average price of the publicly traded securities of the public entity for the 30 consecutive trading days immediately preceding the Performance Period End Date, as reported on the stock exchange composite tape. Each vested PSU is exchangeable for one Unit of the Company. The following table summarizes information related to the Company’s PSU awards: Number of Units Weighted Average Fair Value Total Fair Value ($ in Units outstanding at December 31, 2016 — $ — $ — Units granted 16,350,000 $ 1.41 $ 23,054 Units vested — $ — $ — Units outstanding at December 31, 2017 16,350,000 $ 1.41 $ 23,054 Compensation expense associated with the PSU awards for the year ended December 31, 2017 was $0.4 million and is included in general and administrative expenses on the accompany statement of operations. Unrecognized expense as of December 31, 2017 for all outstanding PSU awards was $22.7 million and will be recognized over a weighted-average remaining period of 3.0 years. The grant date fair value of the PSUs was determined using a Monte Carlo simulation model, which results in an estimated percentage of performance share units earned and estimated Company value on the Performance Period End Date. The grant date fair value of the PSUs is expensed on a straight-line basis from the grant date to the Performance Period End Date. The Monte Carlo simulation process is a generally accepted statistical technique used, in this instance, to simulate the future Unit price and overall market value of the Company. The simulation uses a risk-neutral framework along with the risk-free rate of return, and an estimate for equity volatility of the Company based on peer companies. A Unit price path is simulated for the Company and is used to determine the payout percentages and the Unit price of the Company’s Units as of the Performance Period End Date. The ending Unit price is multiplied by the payout percentage to determine the projected payout, which is then discounted using the risk-free rate of return to the grant date to determine the grant date fair value of the PSUs for that iteration. When enough iterations are generated within a Monte Carlo simulation model, the resulting distribution gives a reasonable estimate of the range of future expected Unit prices and grant date fair value of the PSUs. The following assumptions were used for the Monte Carlo simulation model to determine the grant date fair value and associated compensation expense for the PSU awards granted in December 2017: Company enterprise value $ 3.76 billion Equity volatility 35.00 % Weighted average risk-free interest rate 1.94 % |

Costs Incurred in Oil and Natural Gas Property Acquisition, Exploration and Development Costs incurred in oil, natural gas and NGL property acquisition, exploration and development activities are summarized as follows: Year Ended December 31, 2017 2016 2015 (in thousands) Acquisition costs of properties: Proved properties $ 214,647 $ 1,079 $ 2,291 Unproved properties 1,018,978 93,705 42,266 Exploratory 8,538 — — Development costs 390,991 152,284 24,446 Costs incurred $ 1,633,154 $ 247,068 $ 69,003 Capitalized Costs Relating to Oil, Natural Gas and NGL Producing Activities Capitalized costs related to the Company’s oil, natural gas and NGL producing activities are summarized as follows: December 31, 2017 2016 (in thousands) Oil and natural gas properties Proved $ 750,492 $ 184,376 Unproved 1,126,459 141,004 Less: accumulated depreciation, depletion, amortization and impairment (78,307 ) (27,002 ) Oil and natural gas properties, net $ 1,798,644 $ 298,378 Oil, Natural Gas and NGL Reserves Proved oil, natural gas and NGL estimates at December 31, 2017 were prepared by DeGolyer and MacNaughton, independent petroleum engineers. Proved oil, natural gas and NGL estimates at December 31, 2016 and 2015 were prepared by Ralph E. Davis, independent petroleum engineers. Proved reserves were estimated in accordance with guidelines established by the SEC, which require that reserve estimates be prepared under existing economic and operating conditions based upon the 12-month Oil (mbbl) Natural Gas (mmcf) NGLs (mbbl) Total (Mboe) Proved reserves at December 31, 2014 81 1,798 38 419 Purchase of reserves 45 608 14 160 Extensions and discoveries 279 6,504 632 1,995 Revisions of previous estimates 79 41 42 128 Production (97 ) (434 ) (48 ) (217 ) Proved reserves at December 31, 2015 387 8,517 678 2,484 Purchase of reserves 22 333 33 111 Extensions and discoveries 2,632 33,218 2,956 11,124 Revisions of previous estimates 598 4,145 398 1,687 Production (740 ) (6,382 ) (546 ) (2,350 ) Proved reserves at December 31, 2016 2,900 39,831 3,519 13,057 Purchase of reserves 9,843 163,638 16,870 53,986 Extensions and discoveries 30,554 486,510 61,599 173,238 Revisions of previous estimates (3,583 ) 20,844 (260 ) (369 ) Production (2,294 ) (24,953 ) (2,150 ) (8,603 ) Proved reserves at December 31, 2017 37,420 685,869 79,578 231,309 At December 31, 2017, the Company had approximately 231,309 mboe of proved reserves. The purchase of reserves for the year ended December 31, 2017 includes reserves acquired in the Linn Acquisition. Extensions and discoveries reflect the Company’s 2017 drilling activity in Central Oklahoma. Partially offsetting the additions of reserves was production. At December 31, 2016, the Company had approximately 13,057 mboe of proved reserves. Extensions and discoveries were partially offset by production in 2016. As Citizen acquired approximately 62,500 net acres of unproved leasehold in 2016, the addition of reserves, resulting from drilling activity in 2016, related to this acquired unproved leasehold was included as extensions and discoveries. At December 31, 2015, the Company had approximately 2,484 mboe of proved reserves. Extensions and discoveries, resulting from Citizen’s 2015 drilling results, were partially offset by production for 2015. The following reserve information sets forth the estimated quantities of proved developed and proved undeveloped (“PUD”) oil, natural gas and NGL reserves of the Company as of December 31, 2017, 2016, and 2015: December 31, 2017 2016 2015 Proved Developed Reserves Oil (mbbl) 12,352 2,900 387 Natural gas (mmcf) 259,193 39,831 8,517 NGL (mbbl) 24,034 3,519 678 Total (mboe) 79,585 13,057 2,484 Proved Undeveloped Reserves Oil (mbbl) 25,068 — — Natural gas (mmcf) 426,676 — — NGL (mbbl) 55,544 — — Total (mboe) 151,724 — — Total Proved Reserves Oil (mbbl) 37,420 2,900 387 Natural gas (mmcf) 685,869 39,831 8,517 NGL (mbbl) 79,578 3,519 678 Total (mboe) 231,309 13,057 2,484 In accordance with SEC regulations, the Company uses the 12-month 12-month All estimates of proved reserves are determined according to the rules prescribed by the SEC in existence at the time estimates were made. These rules require that the standard of “reasonable certainty” be applied to proved reserve estimates, which is defined as having a high degree of confidence that the quantities will be recovered. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as more technical and economic data becomes available, a positive or upward revision or no revision is much more likely than a negative or downward revision. Estimates are subject to revision based upon a number of factors, including many factors beyond the Company’s control such as reservoir performance, prices, economic conditions, and government restrictions. In addition, results of drilling, testing, and production subsequent to the date of an estimate may justify revision of that estimate. Reserve estimates are often different from the quantities of oil, natural gas, and NGLs that are ultimately recovered. Estimating quantities of proved oil, natural gas and NGL reserves is a complex process that involves significant interpretations and assumptions and cannot be measured in an exact manner. It requires interpretations and judgment of available technical data, including the evaluation of available geological, geophysical and engineering data. The accuracy of any reserve estimate is highly dependent on the quality of available data, the accuracy of the assumptions on which they are based upon, economic factors, such as oil, natural gas and NGL prices, production costs, severance and excise taxes, capital expenditures, workover and remedial costs, and the assumed effects of governmental regulation. In addition, due to the lack of substantial, if any, production data, there are greater uncertainties in estimating PUD reserves, proved developed non-producing The meaningfulness of reserve estimates is highly dependent on the accuracy of the assumptions on which they were based. In general, the volume of production from oil and natural gas properties the Company owns declines as reserves are depleted. Except to the extent the Company conducts successful exploration and development activities or acquires additional properties containing proved reserves, or both, the Company’s proved reserves will decline as reserves are produced. Results of Operations for Oil, Natural Gas and NGL Producing Activities The following table sets forth the Company’s results of operations for oil, natural gas and NGL producing activities for the years ended December 31, 2017, 2016 and 2015: For the Years Ended December 31, 2017 2016 2015 (in thousands) Oil, natural gas, and NGL sales $ 166,385 $ 54,965 $ 5,685 Production expenses 16,872 5,090 549 Gathering, transportation and processing 18,602 5,920 273 Production taxes 3,685 1,087 190 Exploration expenses 28,154 — 121 Depreciation, depletion and amortization 36,979 24,909 2,060 Accretion of asset retirement obligations 364 87 31 Impairment 4,475 5,258 121 Results of operations $ 57,254 $ 12,614 $ 2,461 Standardized Measure of Discounted Future Net Cash Flows The following summary sets forth the Company’s standardized measure of discounted future net cash flows relating from its proved oil, natural gas and NGL reserves.

Summary of Significant Accounting Policies | Note 2 – Summary of Significant Accounting Policies For a description of the Company’s significant accounting policies, refer to Note 2 to the financial statements included in its 2017 annual financial report. The accompanying financial statements were prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Interim Financial Statements The accompanying condensed financial statements as of December 31, 2017 were derived from the audited financial statements contained in the Company’s 2017 annual financial report. The unaudited interim condensed financial statements for the six months ended June 30, 2018 and 2017 were prepared by the Company in accordance with the accounting policies stated in the audited financial statements included in its 2017 annual financial report. In the opinion of management, the Company’s unaudited condensed financial statements reflect all known adjustments necessary to fairly state the financial position of the Company and its results of operations and cash flows for such periods. All such adjustments are of a normal, recurring nature. Certain information and disclosures normally included in financial statements prepared in conformity with GAAP have been condensed or omitted, although the Company believes that the disclosures contained herein are adequate to make the information presented not misleading. These unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s 2017 annual financial report. Use of Estimates The preparation of financial statements and related footnotes in conformity with GAAP requires that management formulate estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent assets and liabilities. A significant item that requires management’s estimates and assumptions is the estimate of proved oil, natural gas and natural gas liquid (“NGLs”) reserves which are used in the calculation of depletion of the Company’s oil and natural gas properties and impairment, if any, of proved oil and natural gas properties. Changes in estimated quantities of its reserves could impact the Company’s reported financial results as well as disclosures regarding the quantities and value of proved oil and natural gas reserves. Although management believes these estimates are reasonable, actual results could differ from these estimates.

Revenue from Contract with Customer [Abstract] | |
Revenue from Contracts with Customers | Note 3 – Revenue from Contracts with Customers The Company adopted ASC 606 on January 1, 2018 using a modified retrospective approach, which only applies to contracts that were not completed as of the date of initial application. The adoption did not require an adjustment to opening retained earnings for the cumulative effect adjustment. The adoption does not have a material impact on the timing of the Company’s revenue recognition or its financial position, results of operations, net income, or cash flows, but does impact the Company’s presentation of revenues and expenses under the gross-versus-net 2016-08. The following table shows the impact of the adoption of ASC 606 on the Company’s current period results as compared to the previous revenue recognition standard, ASC Topic 605, Revenue recognition Six months ended June 30, 2018 In thousands Under ASC Under ASC Increase/ Revenues: Oil sales $ 122,369 $ 122,369 $ — Natural gas sales 30,897 39,181 (8,284 ) Natural gas liquid sales 38,271 48,539 (10,268 ) Operating expenses: Gathering, transportation and processing — 18,552 (18,552 ) Net income $ 12,324 $ 12,324 $ — Oil Sales Most of the Company’s oil contracts transfer physical custody and title at or near the wellhead, which is commonly when control of the oil has been transferred to the purchaser. The Company’s oil production is primarily sold under market-sensitive contracts that are typically priced at a differential to the New York Mercantile Exchange (“NYMEX”) price. Any differentials incurred after the transfer of control of the oil are net against oil sales as they represent part of the transaction price of the contract. For its oil contracts, the Company generally records its sales based on the net amount received. Natural Gas and NGL Sales Most of the Company’s natural gas is sold at the wellhead or inlet to the processor’s facility, which is commonly when control of the natural gas has been transferred to the purchaser. The natural gas is sold under percentage of proceeds processing contracts. Under these contracts, the purchaser gathers the natural gas where it is produced and transports it via pipeline to natural gas processing plants where NGL products are extracted. The NGL products and remaining residue gas are then sold by the purchaser. Under the natural gas percentage of proceeds contracts, the Company receives a percentage of the value for the extracted NGLs and the residue gas. For its natural gas processing contracts, the Company generally records its natural gas and natural gas liquid sales net of gathering, processing, and transportation expenses based on a principal versus agent assessment for individual contracts. Performance Obligations The Company satisfies the performance obligations under its oil and natural gas sales contracts through delivery of its production and transfer of control to a customer. Upon delivery of production, the Company has the right to receive consideration from its customers in amounts that correspond with the value of the production transferred. The Company’s oil sales contracts are short-term in nature with a contract term of one year or less. For those contracts, the Company utilized the practical expedient in ASC 606-10-50-14 For the Company’s natural gas and NGL sales contracts that have a contract term greater than one year, the Company utilized the practical expedient in ASC 606-10-50-14(A) Contract Balances The Company recognizes sales of oil, natural gas, and NGLs at a point in time when it satisfies a performance obligation and at that point the Company has an unconditional right to receive payment. Accordingly, these contracts do not give rise to contract assets or contract liabilities under ASC 606. The Company had accounts receivable related to revenue from contracts with customers of approximately $29.5 million as of June 30, 2018 which represent this unconditional right to receive payment. Prior Period Performance Obligations To record revenues for oil, natural gas and natural gas liquid sales, the Company estimates the amount of production delivered at the end of each month and the prices expected to be received for those sales. Differences between estimated revenues and actual amounts received for all prior months are recorded in the month payment is received from the customer. For the six months ended June 30, 2018, revenue recognized related to performance obligations satisfied in prior reporting periods was not material. |

Although management believes these estimates are reasonable, actual results could differ from these estimates. |
Revenue Recognition | Revenue Recognition Revenues from the sale of oil, natural gas and NGLs are recognized when the product is delivered at a fixed or determinable price, title has transferred and collectability is reasonably assured. The Company recognizes revenues from the sale of oil, natural gas and NGLs using the sales method, whereby revenue is recorded based on the Company’s share of volumes sold. If the Company’s aggregate sales volumes for a well are greater (or less) than its proportionate share of production from the well, a liability (or receivable) is established to the extent there are insufficient proved reserves available to make up the overproduced (or under produced) imbalance. There were no material imbalances at December 31, 2017 or 2016. | |
Business Combinations | Business Combinations The Company accounts for all business combinations using the acquisition method, which involves the use of significant judgment. In a business combination, the acquiring company must allocate the cost of the acquisition to assets acquired and liabilities assumed based on fair values as of the acquisition date. Any excess or shortage of amounts assigned to assets and liabilities over or under the purchase price is recorded as a gain on bargain purchase or goodwill. The Company estimates the fair values of assets acquired and liabilities assumed in a business combination using various assumptions (all of which are Level 3 inputs within the fair value hierarchy). The most significant assumptions typically relate to the estimated fair values assigned to proved and unproved oil and natural gas properties. To estimate the fair values of the proved and unproved oil and natural gas properties, the Company develops estimates of oil, natural gas and NGL reserves. Estimates of reserves are based on the quantities of oil, natural gas and NGLs that geological and engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under existing economic and operating conditions. Additionally, a risk factor is applied to reserves by reserve type based on industry standards. The Company estimates future prices to apply to the estimated net quantities of reserves based on the applicable ownership percentage acquired and estimates future operating and development costs to arrive at estimates of future net cash flows. The future net cash flows are discounted using a market-based weighted average cost of capital rate determined appropriate at the time of the acquisition. | |
Oil and Natural Gas Properties | Oil and Natural Gas Properties The Company follows the successful efforts method to account for its exploration and production activities. Under this method, costs incurred to purchase, lease, or otherwise acquire a property, whether unproved or proved, are capitalized when incurred. The Company initially capitalizes exploratory well costs pending a determination whether proved reserves have been found. At the completion of drilling activities, the costs of exploratory wells remain capitalized if a determination is made that proved reserves have been found. If no proved reserves have been found, the costs of exploratory wells are charged to expense. In some cases, a determination of proved reserves cannot be made at the completion of drilling, requiring additional testing and evaluation of the wells. Other exploration costs, including geological and geophysical costs, delay rentals and administrative costs associated with unproved property and unsuccessful exploratory well costs are expensed as incurred. Additionally, costs to operate and maintain wells and field equipment are expensed as incurred. Depletion is computed on a units-of-production unit-of-production Unproved properties and the related costs are transferred to proved properties when reserves are discovered on, or otherwise attributed, to the property. The net carrying values of retired, sold or abandoned proved properties that constitute less than a complete unit of depletable property are charged, net of proceeds, to accumulate depreciation, depletion and amortization unless doing so significantly affect the unit-of-production Proceeds from sales of all or a partial interest in individual unproved properties assessed for impairment on a group basis are accounted for as a recovery of costs. No gain or loss is recognized unless the sales proceeds exceed the original cost of the entire interest in the property, in which a gain will be recognized for the excess. | |
Impairment of Oil and Natural Gas Properties | Impairment of Oil and Natural Gas Properties Proved oil and natural gas properties are evaluated for impairment annually or when facts or circumstances indicate that the carrying value of those assets may not be recoverable, such as when there are declines in oil and natural gas prices or well performance. In performing this assessment, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. An impairment loss is indicated if the sum of the estimated undiscounted future cash flows related to an asset group is less than the carrying value of that asset group. If an impairment loss has been incurred, the loss recognized is the excess of the carrying amount over the estimated fair value. The Company calculates the estimated fair value using a discounted future cash flow model. Management’s assumptions associated with the calculation of future cash flows include oil and natural gas prices based on NYMEX futures price strips, as well as other assumptions, including (i) pricing adjustments for differentials, (ii) production costs, (iii) capital expenditures, (iv) production volumes, (v) timing of development, and (vi) estimated reserves. A discount rate, consistent with that used by market participants, is applied to the estimated future cash flows in order to estimate fair value. Cash flow estimates for impairment testing exclude the effects of derivative instruments. It is reasonably possible that the estimate of undiscounted future net cash flows may change in the future resulting in the need to impair carrying values. The primary factors that may affect estimates of future cash flows are (i) oil and natural gas futures prices, (ii) increases or decreases in production and capital costs, (iii) future reserve adjustments, both positive and negative, to proved reserves and appropriate risk-adjusted probable and possible reserves, and (iv) results of future drilling activities. The Company’s unproved properties are assessed for impairment annually, or more frequently if events or changes in circumstances dictated that the carrying value of those assets may not be recoverable. Unproved leasehold costs are amortized on a group basis if individually insignificant, and a valuation allowance is established with a monthly amortization charge to exploration expense for the portion of the properties’ total cost that management estimates may never be transferred to proved properties during the lives of the respective leases. The impairment amortization rate considers the Company’s current drilling plans, the remaining terms of the respective leases and the results of exploratory drilling activity, and can be affected by economic factors including oil and natural gas price outlooks, projected capital costs, and available liquidity. Costs of expired or relinquished leases are charged against the valuation allowance. | |
Drilling Advances | Drilling Advances The Company’s drilling advances consist of cash provided to the Company from its joint interest partners for planned drilling activities. Advances are applied against the joint interest partner’s share of expenses incurred. As noted above, the Company entered into MSAs with Citizen and Linn to perform services, including operating the contributed assets. Any drilling advances due to or from other joint interest owners are maintained by Citizen and Linn. See Note 12 – Transactions with Affiliates | |
Asset Retirement Obligation | Asset Retirement Obligation The Company is obligated to fund the costs of disposing of long-lived assets upon their abandonment. The Company’s asset retirement obligations (“ARO”) relate to the plugging of wells and the related abandonment of oil and natural gas properties. AROs are recognized as liabilities with an increase to the carrying amounts of the related assets when the obligation is incurred. The cost of the asset, including ARO, is depreciated over the useful life of the asset. Fair value of ARO is measured using the expected future cash outflows required to satisfy the retirement obligations discounted at the Company’s credit-adjusted risk-free interest rate. Accretion expense is recognized over time as the discounted liabilities are accreted to their expected settlement value and the liability is settled or the well is sold, at which time the liability is removed. Accretion expense is included in accretion expense in the accompany statements of operations. | |
Derivative Instruments | Derivative Instruments The Company has entered into commodity derivative instruments to reduce the effect of price changes on a portion of the Company’s future oil and natural gas production. The commodity derivative instruments are measured at fair value and are included in the balance sheet as derivative assets and derivative liabilities, on a net basis by counterparty. The Company has not designated any of the derivative contracts as fair value or cash flow hedges for accounting purposes for any of the periods presented. Accordingly, net gains and losses on commodity derivative instruments are recorded based on the changes in the fair values of the derivative instruments and are included in loss on derivative contracts in the accompanying statements of operations. The Company’s cash flow is impacted when the settlements under the commodity derivative contracts result in making or receiving a payment to or from the counterparty and are reflected as operating activities in the Company’s statements of cash flows. The Company’s firm sales contracts qualify for the normal purchase and normal sale exception. Contracts that qualify for this treatment do not require mark-to-market | |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company maintains its cash balances at credit-worthy financial institutions that are insured by the Federal Deposit Insurance Corporation (“FDIC”). At times, cash balances may be in excess of FDIC limits. The Company has not incurred any losses related to the amounts in excess of FDIC limits. | |
Accounts Receivable | Accounts Receivable Accounts receivable consists mainly of receivables from oil, natural gas and NGL purchasers and joint interest owners on properties the Company operates. Accounts receivable from the sale of oil, natural gas and NGLs are accrued based on estimates of the volumetric sales and prices the Company believes it will receive. The Company routinely reviews outstanding balances, assesses the financial strength of its purchasers and joint interest owners and records a reserve for amounts not expected to be fully recovered. The need for an allowance is determined based upon reviews of individual accounts, existing economic conditions and other pertinent factors. No bad debt expense was recorded for the years ended December 31, 2017, 2016 or 2015 and the Company had no reserve for bad debts at December 31, 2017 or 2016. | |
Deferred Financing Costs | Deferred Financing Costs Costs incurred in connection with the Company’s debt are capitalized and amortized as interest expense over the scheduled maturity period. Unamortized costs are associated with the Company’s revolving credit facility and are reflected as a component of long-term assets on the accompanying balance sheets. | |
Equity-Based Compensation | Equity-Based Compensation In December 2017, the Company granted certain employees performance share units (“PSUs”) pursuant to the Roan Resources LLC Management Incentive Plan (the “Plan”). PSUs issued under this Plan were recognized as equity awards based on their characteristics. The compensation measurement was based on the grant date fair value of the award. Equity compensation is recognized over the requisite service period. For employees directly involved in exploration and development activities, equity compensation is capitalized to the Company’s oil and natural gas properties. Equity compensation not capitalized is recognized in general and administrative expenses or production expense in the statements of operations. | |
Comprehensive Income | Comprehensive Income The Company has no elements of comprehensive income other than net income. | |
Concentrations of Credit Risk | Concentrations of Credit Risk The Company sells oil, natural gas and NGLs to various types of customers. The future availability of a ready market for oil, natural gas and NGL depends on numerous factors outside the Company’s control, none of which can be predicted with certainty. Additionally, limitations on capacity at processing plants could also impact the Company’s ability to sell its oil, natural gas and NGLs. The Company is subject to credit risk resulting from the concentration of its oil, natural gas and NGL receivables with two significant purchasers. The Company does not believe the loss of any single purchaser would materially impact its results of operations because oil, natural gas and NGLs are fungible products with well-established markets and numerous purchasers. For the years ended December 31, 2017, 2016, and 2015, the Company had the following major customers that exceeded 10% of total oil, natural gas and NGL revenues: Year Ended 2017 2016 2015 Sunoco Inc. 40 % 55 % 61 % EnLink Oklahoma Gas Processing, LP 39 % 31 % * Cimarex Energy Company * * 14 % * Revenue from customer was less than 10% in this year The Company’s derivative transactions have been carried out in the over-the-counter over-the-counter | |
Fair Value Measurements | Fair Value Measurements The Company follows a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: Level 1— Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date. Level 2— Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in active markets included in Level 1 that are either directly or indirectly observable as of the reporting date. Level 3— Unobservable inputs that are not corroborated by market data and may be used with internally developed methodologies that result in management’s best estimate of fair value. Reclassifications of fair value between Level 1, Level 2 and Level 3 of the fair value hierarchy, if applicable, are made at the end of each quarter. There were no transfers between levels during 2017 or 2016. The carrying values of the Company’s receivables, payables and long-term debt are estimated to be substantially the same as their fair values at December 31, 2017 and 2016. As noted above, the Company carries its derivative financial instruments at fair value | |
Commitments and Contingencies | Commitments and Contingencies The Company is subject to legal proceedings, claims, and liabilities that arise in the ordinary course of business. An accrual is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based on the anticipated most likely outcome or the minimum amount within a range of possible outcomes. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. The amount of ultimate loss may differ from these estimates. Except for environmental contingencies acquired in a business combination, which are recorded at fair value, the Company accrues losses associated with environmental obligations when such losses are probable and can be reasonably estimated. | |
Earnings per Unit | Earnings per Unit The Company uses the treasury stock method to determine the potential dilutive effect of outstanding performance share units. Refer to Note 11 – Performance Share Units | |
Income Taxes | Income Taxes The Company is organized as a Delaware limited liability company. The Company is treated as a flow-through entity for income tax purposes. As a result, the net taxable income or loss of the Company and any related tax credits, for federal income tax purposes, are deemed to pass to the members and are included in the Company’s tax returns even though such net taxable income or loss and tax credits may not have actually been distributed. Accordingly, no tax provision has been made in the financial statements of the Company since the income tax is an obligation of the members. | |
Risks and Uncertainties | Risks and Uncertainties Historically, the markets for oil, natural gas, and NGLs have experienced significant price fluctuations. Price fluctuations can result from variations in weather, regional levels of production, availability of transportation capacity, and various other factors. Increases or decreases in the prices the Company receives for its production could have a significant impact on the Company’s future results of operations and reserve quantities. A portion of the Company’s oil and natural gas production may be interrupted, or shut in, from time to time for various reasons, including, but not limited to, as a result of accidents, weather conditions, the unavailability of gathering, processing, compression, transportation or refining facilities or equipment or field labor issues, or intentionally as a result of market conditions such as oil or natural gas prices that the Company deems uneconomic. If a substantial amount of the Company’s production is interrupted or shut in, the Company’s cash flows and, in turn, it’s financial condition and results of operations could be materially and adversely affected. | |
