Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	Organization and Business Operations Organization PennTex Midstream Partners, LP (the “Partnership”) is a growth oriented limited partnership formed by PennTex Midstream Partners, LLC (“PennTex Development”) to own, operate and develop midstream assets. On June 9, 2015, the Partnership completed its initial public offering (the “Offering”) of 11,250,000 common units representing limited partner interests at a price of $20.00 per unit, and the Partnership subsequently sold 644,462 common units pursuant to the partial exercise of the underwriters’ over-allotment option. A registration statement on Form S-1 (File No. 333-199020) relating to the Offering was filed by the Partnership with the U.S. Securities and Exchange Commission (“SEC”) and was declared effective on June 3, 2015. The Partnership’s common units trade on the NASDAQ Global Select Market under the symbol “PTXP.” PennTex Development was formed by Natural Gas Partners (“NGP”) and members of its management team to develop multi-basin midstream growth platforms focused on organic growth projects in partnership with oil and natural gas producers. On March 17, 2014, PennTex NLA Holdings, LLC, a wholly-owned subsidiary of PennTex Development (“PennTex NLA”), entered into a joint venture, PennTex North Louisiana, LLC (“PennTex Operating”), with MRD WHR LA Midstream LLC, an affiliate of NGP (“MRD WHR LA”), to develop the Partnership’s initial assets. In connection with the closing of the Offering (and giving effect to the partial exercise of the underwriters’ over-allotment option), PennTex NLA and MRD WHR LA contributed their respective 62.5% and 37.5% membership interests in PennTex Operating to the Partnership in exchange for (i) $106.1 million in cash, 5,065,961 common units and 12,500,000 subordinated units to PennTex NLA and (ii) $59.7 million in cash, 3,039,577 common units and 7,500,000 subordinated units to MRD WHR LA. PennTex NLA subsequently distributed all of the cash, common units and subordinated units it received to PennTex Development, which in turn delivered 1,803,942 common units to the holder of its preferred units. Additionally, in connection with the closing of the Offering, the Partnership issued 92.5% and 7.5% of its incentive distributions rights (“IDRs”) to PennTex Development and MRD WHR LA, respectively, and PennTex Development conveyed a 7.5% interest in the Partnership’s general partner to MRD WHR LA. Business The Partnership’s initial assets are located in the Terryville Complex in northern Louisiana and are being developed in two phases. The first phase of development, referred to as Phase I, was completed in May 2015 and includes the Lincoln Parish Plant, a 200 MMcf/d design-capacity, cryogenic natural gas processing plant, and related natural gas gathering and residue gas transportation pipelines. The Partnership expects that the second phase of development, referred to as Phase II, will be completed in September 2015 and will include the Mt. Olive Plant, a 200 MMcf/d design-capacity, cryogenic natural gas processing plant, an NGL transportation pipeline and additions to the existing residue gas pipeline. In addition to the development of the initial assets, the Partnership expects to pursue other opportunities for organic development and growth as producers in the region continue to increase production. MRD Operating LLC, which is a wholly-owned subsidiary of Memorial Resource Development Corp. (“MRD Operating”), an affiliate of NGP, is the Partnership’s primary customer and is a related party. The Partnership operates and manages the business as one reportable segment. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Partnership’s ultimate profitability will depend on, among other factors, completion of construction and commencement of commercial operations of the remaining initial assets.

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these statements include all adjustments (consisting of only normal recurring accruals, unless otherwise disclosed in this report) necessary for their fair presentation. The accompanying interim consolidated financial statements do not include all notes that would be included in the Partnership’s annual financial statements and therefore should be read in conjunction with the historical audited financial statements of PennTex Operating and the footnotes thereto included in the Partnership’s prospectus dated June 3, 2015 and filed with the SEC on June 4, 2015. The statement of operations included in the accompanying unaudited consolidated financial statements also includes expense allocations for certain partnership functions historically performed by PennTex Development, including allocations of general company expenses related to executive oversight, accounting, treasury, tax, legal and procurement and information technology. These allocations are based primarily on specific identification of time and/or activities associated with pre-construction and construction activities, employee headcount or capital expenditures. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from PennTex Development, are reasonable. General company expenses allocated to the Partnership for which the Partnership will reimburse PennTex Development are reflected as a payable due to a related party. These financial statements include the results of operations for PennTex Operating prior to the closing of the Offering on June 9, 2015. As PennTex Operating was under common control with the Partnership prior to the Offering and the Partnership acquired all of the membership interests of PennTex Operating in connection with the closing of the Offering, the contributed assets and liabilities of PennTex Operating were recorded in the consolidated financial statements of the Partnership at historical cost. Prior to the contribution, the Partnership had no operations and nominal assets and liabilities. Use of Estimates The financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the balance sheet date, the reported amounts of expense and disclosure of contingencies. This includes estimates made in the assessment of potential impairment of long-lived assets and estimates used to calculate allocation of expenses from PennTex Development. The Partnership’s valuation methodology for assessing impairment requires management to make judgments and assumptions based on historical experience and to rely on projections of future operating performance. Although management believes these estimates are reasonable, actual results could differ from such estimates. Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less are considered to be cash equivalents. Accounts Receivable Accounts receivable are related to gathering, processing and other services provided to independent natural gas producer customers and are recorded in the Consolidated Balance Sheet net of an allowance for doubtful accounts, if necessary. At June 30, 2015 and December 31, 2014 , the Partnership had accounts receivable with a related party of $2.3 million and $22 thousand , respectively, related to the transportation, gathering and processing services. Intangible Assets Intangible assets consist primarily of rights-of-way and land leases. Intangible assets are amortized over the shorter of the contractual terms, ranging from 71 years to in-perpetuity, or the estimated useful life of the plants or pipeline systems, which is 30 years upon commencement of operations. Property, Plant and Equipment Property, plant and equipment are recorded at historical cost of construction or acquisition. Expenditures for maintenance and repairs that do not add capacity or extend the useful life of an asset are expensed as incurred. Expenditures to extend the useful lives of the assets or enhance their productivity or efficiency from their original design are capitalized and depreciated over the expected remaining period of use. The carrying value of the assets is based on estimates, assumptions and judgments relative to useful lives and salvage values. Sales or retirements of assets, along with the related accumulated depreciation, are removed from the accounts and any gain or loss on disposition is included in the statement of operations. Costs related to projects during construction, including, as applicable, interest on funds borrowed to finance the construction of facilities, are capitalized as construction in progress. Depreciation of property, plant and equipment is recorded on a straight-line basis over the estimated useful lives. These estimates are based on various factors including age (in the case of acquired assets), manufacturing specifications, technological advances and historical data concerning useful lives of similar assets. The useful lives for the various classes of depreciable assets are as follows: Range of Useful Lives (in years) Gathering, processing and transportation 30 Vehicles 5 Hardware and software 5 to 7 General and other 3 to 7 Management reviews property, plant and equipment for impairment periodically, as well as whenever events or changes in circumstances have indicated that the carrying amount of property, plant and equipment might not be recoverable. No impairments related to property, plant and equipment were recorded for the period from March 17, 2014 (inception) through December 31, 2014 . During the three and six month periods ended June 30, 2015 , the Partnership recognized an impairment of surplus equipment of $2.5 million . Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a specified measurement date. Fair value estimates are based on either (a) actual market data or (b) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk. A three-tier hierarchy has been established that classifies fair value amounts recognized or disclosed in the financial statements. The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). The characteristics of fair value amounts classified within each level of the hierarchy are described as follows: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. An active market is one in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 - Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability. Substantially all of these inputs are observable in the marketplace throughout the full term of the asset or liability, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. Level 3 - Measure based on prices or valuation models that require inputs that are both significant to the fair value measurement and are less observable from objective sources (i.e., supported by little or no market activity). The carrying amount of the Partnership’s financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximates fair value due to the short-term maturity of these instruments. Capitalized Interest Capitalized interest is determined by multiplying the Partnership’s weighted-average borrowing cost on debt by the average amount of qualifying costs incurred. Once an asset subject to interest capitalization is completed and placed in service, the associated capitalized interest is expensed through depreciation or impairment. Asset Retirement Obligations Accounting standards related to asset retirement obligations require the Partnership to evaluate whether future asset retirement obligations exist and whether the expected retirement date and the related costs of retirement can be estimated. Management concluded that the Partnership’s assets, which include pipelines and processing plants, will operate for an indeterminate future period when properly maintained. A liability for asset retirement obligations is recorded only if and when a future retirement obligation for assets with a determinable life is identified. There are no asset retirement obligations as of June 30, 2015 because there is not sufficient information to reasonably estimate such obligations and there are no current intentions of discontinuing use of any significant assets. Revenue Recognition The Partnership earns revenue from gathering, processing and transportation services provided to natural gas producers with respect to their natural gas and NGLs. Revenue is recognized when all of the following criteria are met: (i) persuasive evidence of an exchange arrangement exists, (ii) delivery has occurred or service obligations have been fulfilled, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured. Deferred Revenue The Partnership’s gas processing agreement with MRD Operating requires MRD Operating to pay a fee based on the volume of gas actually processed, subject to minimum volume commitments over each quarterly period. To the extent that, in any quarter, MRD Operating fails to deliver the applicable cumulative minimum volume commitment, MRD Operating is required to pay a deficiency fee to the Partnership. The amount paid to the Partnership as a deficiency fee is characterized as unearned revenue, and is reported as deferred revenue, either as other current liabilities or as other non-current liabilities, in the Consolidated Balance Sheets. Deferred revenue is recognized in revenue once all contingencies or potential performance obligations associated with the related volumes have either been satisfied or expired. As of June 30, 2015 the Partnership had deferred revenue in other current liabilities of $0.5 million and none as of December 31, 2014 . As of June 30, 2015 , there was no deferred revenue reported in other non-current liabilities. See Note 9 Commitments and Contingencies for further discussion of the gas processing agreement. Equity-Based Compensation The financial statements reflect various equity-based compensation awards granted by PennTex Development, as well as compensation expense associated with the Partnership’s plans. These awards include profits interests awards, restricted stock, stock options, restricted units, and phantom units. For purposes of these consolidated financial statements, the Partnership recognized as expense in each period the required allocation from PennTex Development. The Partnership recognizes compensation expense related to equity-based awards granted based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Note 6). The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) amended its guidance on revenue recognition. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with earlier adoption not permitted. This guidance can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Partnership is currently evaluating the impact of the provisions of this guidance on the consolidated financial position, results of operations and cash flows. In April 2015, the FASB issued authoritative guidance that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, with earlier adoption permitted. This guidance must be adopted retrospectively to each prior reporting period presented and disclosures will be required for a change in accounting principles. Upon adoption of this standard, the balance of long-term debt, net will be reduced by the balance of debt issuance costs, net on the Consolidated Balance Sheets. In April 2015, the FASB issued authoritative guidance that clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, with earlier adoption permitted. This guidance may be adopted either retrospectively or prospectively to arrangements entered into, or materially modified, after the effective date. The Partnership is currently evaluating the impact of the provisions of this guidance on the consolidated financial position, results of operations and cash flows.

Debt Disclosure [Abstract]
Long-term Debt	Long-term Debt The Partnership’s debt obligations consisted of the following (in thousands) as of the below dates: June 30, 2015 December 31, 2014 $275 million MLP Revolving Credit Facility $ 83,500 $ — $60 million OpCo Revolving Credit Facility — 60,000 Unamortized Debt Discounts (4,067 ) (567 ) Total long-term debt $ 79,433 $ 59,433 $275 million MLP Revolving Credit Facility On December 19, 2014, the Partnership entered into a senior secured revolving credit facility with Royal Bank of Canada, as administrative agent, and a syndicate of lenders that became effective upon the closing of the Offering and matures on December 19, 2019 (the “MLP revolving credit facility”). The agreement provides for a $275 million credit commitment that is expandable up to $400 million under certain conditions. The funds have been used for general purposes, including the funding of capital expenditures. The Partnership’s assets have been pledged as collateral for this credit facility. The MLP revolving credit facility contains various covenants and restrictive provisions that, among other things, limit or restrict the Partnership’s ability to incur or guarantee additional debt, incur certain liens on assets, dispose of assets, make certain distributions (including distributions from available cash, if a default or event of default under the credit agreement then exists or would result from making such a distribution), change the nature of the Partnership’s business, engage in certain mergers or make certain investments and acquisitions, enter into non-arms-length transactions with affiliates and designate certain subsidiaries of the Partnership as “Unrestricted Subsidiaries” for purposes of the credit agreement. Currently, no subsidiaries have been designated as Unrestricted Subsidiaries. Solely with respect to the fiscal quarter ending June 30, 2015 , the Partnership was required to comply with a consolidated debt-to-capital ratio and borrowings under the MLP revolving credit facility were limited to $150.0 million as of June 30, 2015 based on such ratio, of which $64.6 million was available. Commencing with the fiscal quarter ending September 30, 2015, the Partnership is required to comply with a minimum consolidated interest coverage ratio and a maximum consolidated leverage ratio. As of June 30, 2015 , the Partnership was in compliance with the covenants under the MLP revolving credit facility. The borrowed amounts are subject to interest based upon the current consolidated total leverage ratio at the time of the borrowing. At the Partnership’s discretion it can borrow utilizing either Eurodollar loans or an Alternate Base Rate (“ABR” loan). Interest on Eurodollar loans is based on the LIBOR plus an applicable margin that varies between 2.00% and 3.25% based on the consolidated total leverage ratio. Interest on ABR loans is equal to the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Effective Rate in effect on such day plus 1.50% and (c) the Adjusted LIBOR for a one-month interest period on such day plus 1.0% and plus an applicable margin that varies between 1.00% and 2.25% based on the consolidated total leverage ratio. The unused portion of the credit facility is subject to a commitment fee, which is 0.50% multiplied by the amount of the unused commitment. As of June 30, 2015 , the weighted average interest rate on outstanding borrowings was 3.5% . The fair value of the long term-debt approximates the carrying amount because the interest rate is variable and reflective of market rates. The following table sets forth the outstanding borrowings, letters of credit issued and available borrowing capacity under the MLP revolving credit facility as of June 30, 2015 (in thousands): Total size of the MLP revolving credit facility $ 275,000 Total borrowing capacity (covenant limited) $ 150,000 Less: Outstanding borrowings 83,500 Less: Letters of credit issued 1,871 Available borrowing capacity $ 64,629 The Partnership capitalized fees of $1.5 million associated with the MLP revolving credit facility and the Opco revolving credit facility described below, which are included on the Consolidated Balance Sheet as deferred debt issuance costs, and will amortize these fees over the life of the MLP revolving credit facility. Unamortized deferred debt issuance costs as of June 30, 2015 totals $1.4 million . In addition, the Partnership paid debt origination fees of $4.3 million related to the facilities, which are included on the Consolidated Balance Sheet as a contra long-term debt, and will amortize these fees over the life of the MLP revolving credit facility. The Partnership had unamortized debt discount costs of $4.1 million as of June 30, 2015 . $60 million OpCo Revolving Credit Facility of Predecessor On August 29, 2014, PennTex Operating entered into a senior secured revolving credit facility with Royal Bank of Canada, as administrative agent, and a syndicate of lenders that provided for a $60 million credit commitment expandable up to $150 million under certain conditions (the “Opco revolving credit facility”). The funds were used for general purposes, including for capital expenditures incurred to fund the construction of the Partnership’s initial assets. In connection with the closing of the Offering on June 9, 2015, the Partnership repaid all outstanding borrowings and fees under the OpCo revolving credit facility, in the amount of approximately $30.7 million , and terminated this facility.

Equity-Based Awards	Equity-Based Awards PennTex Midstream Partners, LP 2015 Long-term Incentive Plan In connection with the Offering, the board of directors of the Partnership’s general partner adopted the PennTex Midstream Partners, LP 2015 Long-term Incentive Plan (“LTIP”) pursuant to which awards in the form of unrestricted units, restricted units, equity participation units, options, unit appreciation rights, phantom units or distribution equivalent rights may be granted to employees, consultants and directors of the general partner and its affiliates who perform services for or on behalf of the Partnership or its affiliates. Award amounts, vesting requirements and other terms are determined by the board of directors of the general partner at the time of each grant. The LTIP limits the number of units that may be delivered pursuant to vested awards to 3,200,000 common units. LTIP awards that are subsequently canceled, forfeited or withheld to satisfy exercise prices or tax withholding obligations will be available for delivery pursuant to other awards. The LTIP is administered by the board of directors of the Partnership’s general partner or a committee thereof, which is referred to as the plan administrator. The plan administrator may terminate or amend the LTIP at any time with respect to any units for which a grant has not yet been made. The plan administrator also has the right to alter or amend the LTIP or any part of the plan from time to time, including increasing the number of units that may be granted subject to the requirements of the exchange upon which the common units are listed at that time. However, no change in any outstanding grant may be made that would materially reduce the rights or benefits of the participant without the consent of the participant. The LTIP will expire upon termination by the plan administrator. Phantom Units Granted in Connection with the Offering In connection with the completion of the Offering, the Partnership granted an aggregate of 620,200 phantom units with a vesting period of three years and corresponding distribution equivalent rights (“DERs”) to employees and officers of the general partner and its affiliates. A phantom unit entitles the grantee to receive a common unit upon the vesting date. Phantom units do not convey voting rights; however each phantom unit was granted in tandem with a corresponding DER that allows the holder to receive, for each phantom unit held, cash equal to any cash distribution paid on a common unit between the grant date and the date that the phantom units are settled or forfeited. The total value at grant date was $12.2 million , of which $0.2 million was amortized during the period ending June 30, 2015 . As of June 30, 2015 , there was $12.0 million of unrecognized expense. The Partnership also granted 5,000 phantom units with a vesting period of one year to a non-employee director of the general partner. The total value at grant was $0.1 million , of which $5 thousand was amortized during the period ending June 30, 2015 .

Equity [Abstract]
Partnership and Equity Distributions	Partnership and Equity Distributions Minimum Quarterly Distribution The partnership agreement provides for a minimum quarterly distribution of $0.2750 per unit for each quarter, or $1.10 per unit on an annualized basis. On July 23, 2015, the Partnership announced a pro-rated distribution of $0.0665 per common unit for the second quarter of 2015. This amount represents the minimum quarterly distribution of $0.2750 per unit, or $1.10 per unit on an annualized basis, pro-rated for the period from June 9, 2015 through June 30, 2015. This distribution will be paid on August 14, 2015 to unitholders of record on August 4, 2015. The payment of the full minimum quarterly distribution on the outstanding common units and subordinated units requires the Partnership to have cash available for distribution of approximately $11.0 million per quarter, or $44.0 million per year. The partnership agreement requires that distributions for each quarter will be paid to the extent there is sufficient cash after establishment of cash reserves and payment of fees and expenses, including payments to the general partner and its affiliates. The Partnership’s ability to pay the minimum quarterly distribution is subject to various restrictions and other factors. The partnership agreement generally provides for distributions of cash each quarter during the subordination period in the following manner: • first, to the holders of common units, until each common unit has received the minimum quarterly distribution of $0.2750 plus any arrearages from prior quarters; • second, to the holders of subordinated units, until each subordinated unit has received the minimum quarterly distribution of $0.2750 ; and • third, to the holders of common units and subordinated units pro rata until each has received a distribution of $0.3163 . If cash distributions to the unitholders exceed $0.3163 per common unit and subordinated unit in any quarter, the unitholders and the holders of the IDRs will receive distributions according to the following percentage allocations: Total Quarterly Distribution Marginal percentage interest in distributions Target Amount Unitholders IDRS above $0.2750 up to $0.3163 100 % — % above $0.3163 up to $0.3438 85 % 15 % above $0.3438 up to $0.4125 75 % 25 % above $0.4125 50 % 50 % Subordinated Units The Partnership has 20,000,000 subordinated units outstanding, of which PennTex Development owns 12,500,000 subordinated units. The principal difference between the common units and subordinated units is that, for any quarter during the subordination period, holders of the subordinated units are not entitled to receive any distribution from operating surplus until the common units have received the minimum quarterly distribution from operating surplus for such quarter plus any arrearages in the payment of the minimum quarterly distribution from prior quarters. Subordinated units will not accrue arrearages. When the subordination period ends, all of the subordinated units will convert into an equal number of common units. Except as described below, the subordination period began on the closing date of the Offering (June 9, 2015) and extends until the first business day following the distribution of available cash in respect of any quarter beginning after September 30, 2018, that each of the following tests are met: • distributions of available cash from operating surplus on each of the outstanding common units and subordinated units equaled or exceeded $1.10 (the annualized minimum quarterly distribution), for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date; • the adjusted operating surplus (as defined below) generated during each of the three consecutive, nonoverlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of $1.10 (the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units during those periods on a fully diluted basis; and • there are no arrearages in payment of the minimum quarterly distribution on the common units. Notwithstanding the foregoing, the subordination period will automatically terminate on the first business day following the distribution of available cash in respect of any quarter, beginning with the quarter ending September 30, 2016, that each of the following tests are met: • distributions of available cash from operating surplus on each of the outstanding common units and subordinated units equaled or exceeded $1.65 ( 150% of the annualized minimum quarterly distribution), plus the related distributions on the incentive distribution rights, for the four-quarter period immediately preceding that date; • the adjusted operating surplus (as defined below) generated during the four-quarter period immediately preceding that date equaled or exceeded the sum of (1) $1.65 ( 150% of the annualized minimum quarterly distribution) on all of the outstanding common units and subordinated units during that period on a fully diluted basis and (2) the corresponding distributions on the incentive distribution rights; and • there are no arrearages in payment of the minimum quarterly distributions on the common units. To the extent there is cash available for distribution from operating surplus in any future quarter during the subordination period in excess of the amount necessary to pay the minimum quarterly distribution to holders of the common units, in a period following the subordination period, the Partnership will use this excess cash to pay any distribution arrearages on common units related to prior quarters before any cash distribution is made to holders of subordinated units. If the Partnership does not pay the minimum quarterly distribution on the common units for any quarter following the subordination period, the common unitholders will not be entitled to receive such arrearage payments.

Earnings per Unit

Earnings Per Share [Abstract]
Earnings per Unit	Earnings per Unit The Partnership’s net income is allocated to the limited partners, including the holders of the subordinated units, in accordance with their respective ownership percentages, after giving effect to incentive distributions paid. Basic and diluted net income per limited partner unit is calculated by dividing limited partners’ interest in net income, less incentive distributions, by the weighted average number of outstanding common units and subordinated units during the period. The Partnership computes earnings per unit using the two-class method for master limited partnerships as prescribed in the guidance Accounting Standards Codification (“ASC”) 260. The two-class method requires that securities that meet the definition of a participating security be considered for inclusion in the computation of basic earnings per unit. Under the two-class method, earnings per unit is calculated as if all of the earnings for the period were distributed under the terms of the partnership agreement of the Partnership, regardless of whether the general partner has discretion over the amount of distributions to be made in any particular period, whether those earnings would actually be distributed during a particular period from an economic or practical perspective, or whether the general partner has other legal or contractual limitations on its ability to pay distributions that would prevent it from distributing all of the earnings for a particular period. The Partnership calculates net income available to limited partners based on the distributions pertaining to the current period’s net income. After adjusting for the appropriate period’s distributions, the remaining undistributed earnings or excess distributions over earnings, if any, are allocated to the general partner and limited partners in accordance with the contractual terms of the partnership agreement and as further prescribed in the guidance in ASC 260 under the two-class method. The two-class method does not impact the overall net income or other financial results; however, in periods in which aggregate net income exceeds its aggregate distributions for such period, it will have the impact of reducing net income per limited partner unit. This result occurs as a larger portion of the aggregate earnings, as if distributed, is allocated to the incentive distribution rights of the general partner, even though the Partnership makes distributions on the basis of available cash and not earnings. In periods in which the aggregate net income does not exceed its aggregate distributions for such period, the two-class method does not have any impact on the calculation of earnings per limited partner unit. Basic earnings per unit is computed by dividing net earnings attributable to unitholders by the weighted average number of units outstanding during each period. Diluted earnings per unit reflects the potential dilution of common equivalent units that could occur if equity participation units are converted into common units. As the Offering was completed on June 9, 2015, no income from the period from January 1, 2015 to June 9, 2015 is allocated to the common and subordinated units issued on June 9, 2015, and all income for such period was allocated to the general partner or predecessor operations. The following table illustrates the Partnership’s calculation of net income per unit for the three and six months ended June 30, 2015: Three Months Ended June 30, 2015 Six Months Ended June 30, 2015 (in thousands, except unit and per unit amounts) Net income (loss) attributable to the partnership subsequent to the Offering (1) $ (550 ) $ (550 ) Less: General partner’s distribution (2) — — Distribution declared on IDRs (2) — — Distribution equivalents (2)(3) 42 42 Limited partners’ distribution declared on common units (2) 1,330 1,330 Limited partners’ distribution declared on subordinated units (2) 1,330 1,330 Distribution less than (in excess of) net income (loss) attributable to the Partnership subsequent to the Offering $ (3,252 ) $ (3,252 ) (1) For the period from June 9, 2015 to June 30, 2015.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contractual Commitments Gas Processing Agreement The Partnership is a party to a 15 -year gas processing agreement with MRD Operating to provide natural gas processing services at the Partnership’s processing plants. The initial term of the processing agreement commenced on June 1, 2015 and will end on the fifteenth anniversary of the contract effectiveness date for the Mt. Olive plant, which is anticipated to be October 1, 2015. Under the processing agreement, MRD Operating has agreed to deliver a daily minimum volume of gas for processing through the term of the agreement, which is initially 115,000 MMBtu/d. On the contract effectiveness date for the Mt. Olive plant, MRD Operating’s minimum volume commitment will increase to 345,000 MMBtu/d. On July 1, 2016, MRD Operating’s minimum volume commitment will further increase to 460,000 MMBtu/d through June 30, 2026. During the first five years of this ten-year period, MRD Operating may from time to time, upon nine months’ notice, increase the minimum volume commitment in increments of 57,500 MMBtu/d up to an aggregate additional 230,000 MMBtu/d, subject to available capacity. On July 1, 2026, MRD Operating’s minimum volume commitment will return to 345,000 MMBtu/d until the fifteenth anniversary of the in-service date of the Lincoln Parish plant, after which the minimum volume commitment will decrease to 115,000 MMBtu/d through the remainder of the initial term of the processing agreement. Any volumes of gas delivered up to the then-applicable minimum volume commitment will be considered firm reserved gas and be charged the firm fixed-commitment fee, and any volumes delivered in excess of such minimum volume commitment will be considered interruptible volumes and be charged the interruptible-service fixed fee. Pursuant to the processing agreement, MRD Operating will pay a deficiency payment based on the firm-commitment fixed fee with respect to a particular quarterly period if the cumulative minimum volume commitment as of the end of such period exceeds the sum of (i) the cumulative volumes processed under the processing agreement as of the end of such period plus (ii) volumes corresponding to deficiency payments incurred prior to such period. MRD Operating may utilize these deficiency payments as a credit for fees owed to the Partnership only to the extent it has delivered the total minimum volume commitment under the processing agreement within the initial 15 -year term of the agreement. Additionally, all volumes delivered by MRD Operating in excess of the minimum volume commitment in a quarterly period will apply against and reduce, on a one-for-one basis, the cumulative minimum volume commitment used to calculate deficiency payments for future quarterly periods. Deficiency payments are recorded as deferred revenue since MRD Operating may utilize these deficiency payments as credit for fees owed if it has delivered the total minimum volume commitment under the processing agreement within the initial 15 -year term of the agreement. The Partnership will recognize deficiency payments into revenue once all contingencies or potential performance obligations associated with the related volumes have either (i) been satisfied through the processing of future excess volumes of natural gas, or (ii) expired (or lapsed) through the passage of time pursuant to the terms of the processing agreement. On August 5, 2015, the parties amended the processing agreement to provide that MRD Operating may use the $0.5 million deficiency payment incurred with respect to the initial quarterly period, which began on June 1, 2015 and ended June 30, 2015, as a credit against processing fees owed to PennTex Operating for corresponding volumes of gas processed during the third and fourth quarters of 2015 in excess of a specified threshold for each quarter. The specified threshold for the third quarter is 161,000 MMBtu per day (on an average basis) and the specified threshold for the fourth quarter is the then-applicable minimum volume commitment. Additionally, pursuant to the amendment, if MRD Operating does not use the June 2015 deficiency payment to offset processing fees in the third or fourth quarters of 2015, the June 2015 deficiency payment will expire at the end of the fourth quarter of 2015 and may not be used as a credit for any future processing fees owed by MRD Operating. Any portion of the June 2015 deficiency payment that is so credited during the third or fourth quarters will be recognized as revenue during such period, and any unused portion of the June 2015 deficiency payment will be recognized as revenue during the fourth quarter of 2015. Gas Gathering Agreement The Partnership is party to a gathering agreement with MRD Operating that commenced on December 20, 2014 and will remain in effect until June 1, 2030. The gathering agreement provides for the gathering of MRD Operating’s processable natural gas for delivery through the PennTex Gathering Pipeline to the Partnership’s processing plants and for MRD Operating’s payment of fees, including a firm capacity reservation payment and a usage fee component that is subject to a minimum volume commitment. For the period from June 1, 2015 through November 30, 2019, (i) the firm capacity reservation payment is payable for a daily capacity of 460,000 MMBtu/d (subject to certain credits relating to the availability of gathering capacity), calculated monthly, and (ii) the usage fee is payable for volumes delivered into the gathering system, subject to a deficiency fee based on a specified minimum volume commitment that is calculated and paid on an annual basis. The specified minimum gathering volume commitment upon which the deficiency fee calculation is based will be equal to MRD Operating’s then applicable daily minimum volume commitment under the processing agreement (excluding the amount of any optional increase in such minimum processing volume commitment). Accordingly, the amount of such specified minimum gathering volume commitment will not be less than 115,000 MMBtu/d, nor more than 460,000 MMBtu/d. For the period from December 1, 2019 through the end of the gathering agreement term, no firm capacity reservation payment will be payable, and there will be a usage fee component, subject to the deficiency fee and specified minimum volume commitment described above. In addition, the gathering agreement provides for the delivery of MRD Operating’s rich natural gas, on an interruptible basis, to facilities operated by DCP Midstream for a specified usage fee. Gathering volumes delivered to the DCP Midstream facilities are not subject to a deficiency fee or a minimum volume commitment but will be applied against the volume delivery requirements for purposes of the minimum volume commitment under the gathering agreement. Gas Transportation Agreement The Partnership is party to a 15 -year natural gas transportation agreement with MRD Operating that commenced on June 1, 2015. The gas transportation agreement provides for the transportation of residue gas through the Partnership’s residue gas pipeline from the outlet of the Partnership’s processing plants to delivery points at interconnections with third-party natural gas transportation pipelines providing access to Gulf Coast markets. MRD Operating will pay a usage fee for all volumes transported under the gas transportation agreement. While the gas transportation agreement does not provide for a minimum volume commitment, it does include a plant tailgate dedication pursuant to which all of MRD Operating’s residue gas produced from the Partnership’s processing plants will be delivered for transportation on the Partnership’s residue gas pipeline. Transportation Service Agreement The Partnership is party to a 15 -year NGL transportation services agreement with MRD Operating that commences when the Partnership’s NGL pipeline is placed in service, which is expected to occur in October 2015. The NGL transportation agreement provides for the transportation of NGLs through the Partnership’s NGL pipeline from the outlet of the Partnership’s processing plants to a delivery point connecting to DCP Midstream’s Black Lake pipeline in Ada, Louisiana. MRD Operating will pay a usage fee for all volumes transported under the NGL transportation agreement. While the NGL transportation agreement does not provide for a minimum volume commitment, it does include a plant tailgate dedication pursuant to which all of MRD Operating’s NGLs produced from the Partnership’s processing plants will be delivered for transportation on the Partnership’s NGL pipeline. The NGL transportation agreement is subject to the terms of tariff, which the Partnership intends to file with FERC, and which will become effective prior to the in-service date of the Partnership’s NGL pipeline. Services and Secondment Agreement In connection with the closing of the Offering, the Partnership entered into a 10 -year services and secondment agreement with the general partner, PennTex Development and PennTex Midstream Management Company, LLC (“PennTex Management”) pursuant to which PennTex Management seconds certain employees to the general partner to provide operational and maintenance services with respect to the Partnership’s initial assets. The Partnership is obligated to reimburse PennTex Management for the cost of any seconded employees, including wages and benefits. If a seconded employee does not devote 100% of his or her time to providing services to the general partner, the general partner will reimburse PennTex Management for only a prorated portion of such employee’s overall wages and benefits, based on the percentage of the employee’s time spent working for the general partner. PennTex Management bills the general partner monthly in arrears for services provided during the prior month, and payment is due within 15 days of the general partner’s receipt of the invoice. Additionally, the Partnership pays an administrative fee to PennTex Development for the provision of various management and administrative services for the Partnership’s benefit, including executive services of employees of the general partner and its affiliates who devote less than 50% of their business time to the business and affairs, financial and administrative services (including treasury and accounting), information technology, legal services, health, safety and environmental services, human resources services, business development services, investor relations and government relations, tax matters and insurance administration. The administrative fee is paid monthly and, for the year ended December 31, 2015, is calculated as follows: (i) for the period from June 9, 2015 to and including June 30, 2015, the administrative fee was $2,778 per day; (ii) for each month following June 30, 2015 and including the month in which the Mt. Olive plant commences commercial operations, expected to be September 2015, the administrative fee will be $83,333 per month; and (iii) for each month during 2015 after the month in which the Mt. Olive plant commences commercial operations, the administrative fee will be $166,667 . The Partnership is also required to reimburse PennTex Development and its affiliates for all other direct or allocated costs and expenses incurred by them on the Partnership’s behalf under the services and secondment agreement, which is in addition to reimbursement of the general partner and its affiliates for certain costs and expenses incurred on the Partnership’s behalf for managing and controlling the Partnership’s business and operations as required by the partnership agreement. Mt. Olive Gas Plant Sale and Installation Agreement The Partnership is party to a Gas Plant Sale and Installation Agreement with UOP Russell LLC (“UOP”) for the construction and installation of the Mt. Olive plant and related facilities. The agreement is for an amount of $89.0 million , subject to certain early completion incentive payments, and is payable on a schedule based on reaching specific milestones. UOP began mobilization at the construction site in February 2015, at which time the Partnership became liable for the full amount of the contract, subject to and payable upon the later of the UOP meeting certain milestones or specified payment dates. As of June 30, 2015 , $71.0 million has been paid to UOP under this agreement. As of June 30, 2015 , the Partnership has $2.0 million of accrued payables to UOP for the Mt. Olive plant. The title to the Mt. Olive plant will transfer to the Partnership from UOP upon the earlier of (a) the equipment being complete, ready for operation for its intended purpose and commissioned, or (b) January 1, 2016. Guarantees or Other Support The Partnership entered into one or more letters of credit to certain vendors in relation to the construction of the electric infrastructure necessary for supplying power to the processing plants. These letters of credit are backed by the Partnership’s revolving credit facility as collateral support. Legal Proceedings The Partnership may in the future be involved as a party to various legal proceedings, which are incidental to the ordinary course of business. The Partnership regularly analyzes current information and, as necessary, will provide accruals for probable liabilities on the eventual disposition of these matters. In the opinion of management, as of June 30, 2015 , there are no pending legal matters that would have a material impact on the results of operations, financial position or cash flows.

Risks and Uncertainties [Abstract]
Concentrations of Risk	Concentrations of Risk Financial instruments that potentially subject the Partnership to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Partnership maintains cash in bank deposit accounts that, at times, may exceed federally insured limits. The Partnership has not experienced any losses in such accounts to date and does not believe it is exposed to any significant risk. Accounts receivable are from natural gas producers for which the Partnership will gather, process and transport natural gas and transport natural gas liquids. This industry concentration has the potential to impact the Partnership’s overall exposure to credit risk, either positively or negatively, in that the Partnership’s customers may be similarly affected by changes in economic, industry or other conditions. The Partnership will monitor the creditworthiness of counterparties. As disclosed in Note 2 Summary of Significant Accounting Policies-Revenue Recognition, the Partnership has entered into long-term commercial agreements with MRD Operating. The Partnership is dependent on this customer’s credit worthiness and performance under these agreements.

The first phase of development, referred to as Phase I, was completed in May 2015 and includes the Lincoln Parish Plant, a 200 MMcf/d design-capacity, cryogenic natural gas processing plant, and related natural gas gathering and residue gas transportation pipelines. The Partnership expects that the second phase of development, referred to as Phase II, will be completed in September 2015 and will include the Mt. Olive Plant, a 200 MMcf/d design-capacity, cryogenic natural gas processing plant, an NGL transportation pipeline and additions to the existing residue gas pipeline. In addition to the development of the initial assets, the Partnership expects to pursue other opportunities for organic development and growth as producers in the region continue to increase production. MRD Operating LLC, which is a wholly-owned subsidiary of Memorial Resource Development Corp. (“MRD Operating”), an affiliate of NGP, is the Partnership’s primary customer and is a related party. The Partnership operates and manages the business as one reportable segment. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Partnership’s ultimate profitability will depend on, among other factors, completion of construction and commencement of commercial operations of the remaining initial assets. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and with the requirements of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these statements include all adjustments (consisting of only normal recurring accruals, unless otherwise disclosed in this report) necessary for their fair presentation. The accompanying interim consolidated financial statements do not include all notes that would be included in the Partnership’s annual financial statements and therefore should be read in conjunction with the historical audited financial statements of PennTex Operating and the footnotes thereto included in the Partnership’s prospectus dated June 3, 2015 and filed with the SEC on June 4, 2015. The statement of operations included in the accompanying unaudited consolidated financial statements also includes expense allocations for certain partnership functions historically performed by PennTex Development, including allocations of general company expenses related to executive oversight, accounting, treasury, tax, legal and procurement and information technology. These allocations are based primarily on specific identification of time and/or activities associated with pre-construction and construction activities, employee headcount or capital expenditures. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from PennTex Development, are reasonable. General company expenses allocated to the Partnership for which the Partnership will reimburse PennTex Development are reflected as a payable due to a related party. These financial statements include the results of operations for PennTex Operating prior to the closing of the Offering on June 9, 2015. As PennTex Operating was under common control with the Partnership prior to the Offering and the Partnership acquired all of the membership interests of PennTex Operating in connection with the closing of the Offering, the contributed assets and liabilities of PennTex Operating were recorded in the consolidated financial statements of the Partnership at historical cost. Prior to the contribution, the Partnership had no operations and nominal assets and liabilities.
Use of Estimates	Use of Estimates The financial statements have been prepared in conformity with GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the balance sheet date, the reported amounts of expense and disclosure of contingencies. This includes estimates made in the assessment of potential impairment of long-lived assets and estimates used to calculate allocation of expenses from PennTex Development. The Partnership’s valuation methodology for assessing impairment requires management to make judgments and assumptions based on historical experience and to rely on projections of future operating performance. Although management believes these estimates are reasonable, actual results could differ from such estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less are considered to be cash equivalents.
Accounts Receivable	Accounts Receivable Accounts receivable are related to gathering, processing and other services provided to independent natural gas producer customers and are recorded in the Consolidated Balance Sheet net of an allowance for doubtful accounts, if necessary.
Intangible Assets	Intangible Assets Intangible assets consist primarily of rights-of-way and land leases. Intangible assets are amortized over the shorter of the contractual terms, ranging from 71 years to in-perpetuity, or the estimated useful life of the plants or pipeline systems, which is 30 years upon commencement of operations.
Property, Plant and Equipment	Management reviews property, plant and equipment for impairment periodically, as well as whenever events or changes in circumstances have indicated that the carrying amount of property, plant and equipment might not be recoverable. Property, Plant and Equipment Property, plant and equipment are recorded at historical cost of construction or acquisition. Expenditures for maintenance and repairs that do not add capacity or extend the useful life of an asset are expensed as incurred. Expenditures to extend the useful lives of the assets or enhance their productivity or efficiency from their original design are capitalized and depreciated over the expected remaining period of use. The carrying value of the assets is based on estimates, assumptions and judgments relative to useful lives and salvage values. Sales or retirements of assets, along with the related accumulated depreciation, are removed from the accounts and any gain or loss on disposition is included in the statement of operations. Costs related to projects during construction, including, as applicable, interest on funds borrowed to finance the construction of facilities, are capitalized as construction in progress. Depreciation of property, plant and equipment is recorded on a straight-line basis over the estimated useful lives. These estimates are based on various factors including age (in the case of acquired assets), manufacturing specifications, technological advances and historical data concerning useful lives of similar assets.
Fair Value Measurement	The carrying amount of the Partnership’s financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximates fair value due to the short-term maturity of these instruments.
Capitalized Interest	Capitalized Interest Capitalized interest is determined by multiplying the Partnership’s weighted-average borrowing cost on debt by the average amount of qualifying costs incurred. Once an asset subject to interest capitalization is completed and placed in service, the associated capitalized interest is expensed through depreciation or impairment.
Asset Retirement Obligations	Asset Retirement Obligations Accounting standards related to asset retirement obligations require the Partnership to evaluate whether future asset retirement obligations exist and whether the expected retirement date and the related costs of retirement can be estimated. Management concluded that the Partnership’s assets, which include pipelines and processing plants, will operate for an indeterminate future period when properly maintained. A liability for asset retirement obligations is recorded only if and when a future retirement obligation for assets with a determinable life is identified. There are no asset retirement obligations as of June 30, 2015 because there is not sufficient information to reasonably estimate such obligations and there are no current intentions of discontinuing use of any significant assets.
Revenue Recognition	Revenue Recognition The Partnership earns revenue from gathering, processing and transportation services provided to natural gas producers with respect to their natural gas and NGLs. Revenue is recognized when all of the following criteria are met: (i) persuasive evidence of an exchange arrangement exists, (ii) delivery has occurred or service obligations have been fulfilled, (iii) the price is fixed or determinable and (iv) collectability is reasonably assured.
Deferred Revenue	Deferred Revenue The Partnership’s gas processing agreement with MRD Operating requires MRD Operating to pay a fee based on the volume of gas actually processed, subject to minimum volume commitments over each quarterly period. To the extent that, in any quarter, MRD Operating fails to deliver the applicable cumulative minimum volume commitment, MRD Operating is required to pay a deficiency fee to the Partnership. The amount paid to the Partnership as a deficiency fee is characterized as unearned revenue, and is reported as deferred revenue, either as other current liabilities or as other non-current liabilities, in the Consolidated Balance Sheets. Deferred revenue is recognized in revenue once all contingencies or potential performance obligations associated with the related volumes have either been satisfied or expired. As of June 30, 2015 the Partnership had deferred revenue in other current liabilities
Equity Based Compensation	Equity-Based Compensation The financial statements reflect various equity-based compensation awards granted by PennTex Development, as well as compensation expense associated with the Partnership’s plans. These awards include profits interests awards, restricted stock, stock options, restricted units, and phantom units. For purposes of these consolidated financial statements, the Partnership recognized as expense in each period the required allocation from PennTex Development. The Partnership recognizes compensation expense related to equity-based awards granted based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Note 6). The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) amended its guidance on revenue recognition. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with earlier adoption not permitted. This guidance can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption. The Partnership is currently evaluating the impact of the provisions of this guidance on the consolidated financial position, results of operations and cash flows. In April 2015, the FASB issued authoritative guidance that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, with earlier adoption permitted. This guidance must be adopted retrospectively to each prior reporting period presented and disclosures will be required for a change in accounting principles. Upon adoption of this standard, the balance of long-term debt, net will be reduced by the balance of debt issuance costs, net on the Consolidated Balance Sheets. In April 2015, the FASB issued authoritative guidance that clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period, with earlier adoption permitted. This guidance may be adopted either retrospectively or prospectively to arrangements entered into, or materially modified, after the effective date. The Partnership is currently evaluating the impact of the provisions of this guidance on the consolidated financial position, results of operations and cash flows.
