[2]	For the three and nine months ended September 30, 2014 and 2013, we had weighted average preferred units outstanding of 16,666,667. The preferred and Class B units are contingently convertible into common units and could potentially dilute earnings per unit in the future. Upon issuance, 11.6 million of deferred Class B units would also be convertible into common units and could potentially dilute earnings per unit in the future. For the three months ended September 30, 2014, the preferred, the deferred Class B, and the Class B units have been included in the diluted earnings per unit calculation as they were dilutive for the period, however were not included in the nine months ended September 30, 2014 diluted earnings per unit calculation as they were anti-dilutive for the period. The preferred and Class B units have not been included in the diluted earnings per unit calculation for the three and nine months ended September 30, 2013 as they were anti-dilutive for the period.

Organization And Operations	'
	NOTE 1 – ORGANIZATION AND OPERATIONS
	QR Energy, LP (“we,” “us,” “our,” or the “Partnership”) is a Delaware limited partnership formed on September 20, 2010, to acquire oil and natural gas assets from our affiliated entity, QA Holdings, LP (the “Predecessor”) and other third party entities to enhance and exploit oil and gas properties. Certain of the Predecessor’s subsidiaries (collectively known as the “Fund”) include Quantum Resources A1, LP, Quantum Resources B, LP, Quantum Resources C, LP, QAB Carried WI, LP, QAC Carried WI, LP and Black Diamond Resources, LLC.
	Our general partner is QRE GP, LLC (“general partner” or “QRE GP”). As a result of the GP Buyout Transaction (described below), QRE GP became a 100% owned subsidiary of the Partnership. We conduct our operations through our 100%  owned subsidiary QRE Operating, LLC (“OLLC”). Our 100% owned subsidiary, QRE Finance Corporation (“QRE FC”), has no material assets and was formed for the sole purpose of serving as a co-issuer of our debt securities. We also have a controlling interest in East Texas Saltwater Disposal Company (“ETSWDC”), a privately held Texas corporation. The main purpose of ETSWDC is to dispose of salt water generated as a by-product from oil production in the East Texas Oil Field.
	On March 2, 2014, we completed a transaction related to our general partner interest pursuant to a Contribution Agreement, by and among the Partnership, the general partner, QR Holdings (QRE), LLC (“QRH”) and QR Energy Holdings, LLC (“QREH” and, together with QRH, the “QR Parties”), the former owners of our general partner, pursuant to which (i) the general partner reclassified its 0.1% general partner interest in the Partnership, formerly represented by 51,036 general partner units, in exchange for a non-economic general partner interest, (ii) the QR Parties contributed 100% of the limited liability company interests of the general partner to the Partnership, and (iii) the partnership agreement was amended, to, among other things, (a) terminate the management incentive fee and provide for the future issuance of up to 11.6 million Class B units (the “Contingent Class B Units”), subject to certain tests described in Note 13 – Partners Capital, to the QR Parties and (b) provide for the election of all of the members of the board of directors of the general partner by our limited partners beginning in June 2015 (the “GP Buyout Transaction”).
	On July 23, 2014, the Partnership entered into an Agreement and Plan of Merger dated as of July 23, 2014 (the “Merger Agreement”), by and among the Partnership, QRE GP, Breitburn Energy Partners, LP (“Breitburn”), a Delaware limited partnership, Breitburn GP LLC, a Delaware limited liability company and the general partner of Breitburn, and Boom Merger Sub, LLC, a Delaware limited liability company and newly formed, wholly owned subsidiary of Breitburn (“Merger Sub”). Upon the terms and conditions set forth in the Merger Agreement, Merger Sub will be merged with and into the Partnership (the “Merger”), with the Partnership continuing as the surviving entity and as a wholly owned subsidiary of Breitburn. The Merger Agreement was approved by the board of directors of our general partner on July 23, 2014.
	Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each common unit and Class B unit of the Partnership issued and outstanding immediately prior to the Effective Time will be converted into the right to receive 0.9856 Breitburn common units (“Breitburn Units”) (such consideration, the “Unit Consideration”) or, in the case of fractional Breitburn Units, cash (without interest and rounded up to the nearest whole cent) in an amount equal to the product of (i) such fractional part of a Breitburn Unit multiplied by (ii) the average closing price for a Breitburn Unit as reported on the NASDAQ (the “NASDAQ”) for the ten consecutive full trading days ending at the close of trading on the day immediately preceding the closing date of the Merger (the “Closing Date”). In addition, at the Effective Time, each of the Class C convertible preferred units of the Partnership issued and outstanding immediately prior to the Effective Time will be converted into the right to receive cash in an amount equal to (i) $350 million divided by (ii) the number of Class C convertible preferred units outstanding immediately prior to the Effective Time. The number of Class B units issuable upon a change of control of the Partnership will be equal to (i) 6,748,067, minus (ii) the excess of (A) the number of performance units that vest and are settled in common units of the Partnership in connection with the Merger over (B) 383,900 and will be issued and treated as outstanding Class B units and converted into the right to receive the Unit Consideration. In addition, (i) each restricted common unit that is outstanding pursuant to the Partnership’s long-term incentive plan will vest upon the Effective Time and be converted into the right to receive the Unit Consideration and (ii) immediately prior to the Effective Time each performance unit granted pursuant to the Partnership’s long-term incentive plan will vest and be settled with respect to the number of common units issuable determined based on actual attainment of the applicable performance goal(s) as of two business days prior to the Effective Time, with such resulting common units converted at the Effective Time into the right to receive the Unit Consideration.
	The merger is expected to be tax free to the Partnership and tax free to the holders of common units (except to the extent of cash received in lieu of fractional Breitburn Units or any other actual or constructive distribution of cash, including as a result of any decrease in partnership liabilities pursuant to Section 752 of the Internal Revenue Code).
	Simultaneously with the execution of the Merger Agreement, Breitburn entered into a Transaction, Voting and Support Agreement (the “Voting Agreement”) dated as of July 23, 2014 with the Fund and the QR Parties, which provides for, among other things (i) that the Fund and QR Parties will vote all common units, Class B units and Class C units owned by the them in favor of the Merger and the adoption of the Merger Agreement at any meeting of the Partnership’s unitholders called for such purpose and against any alternative proposal or any proposal made in opposition to adoption of the Merger Agreement and (ii) the termination of certain related party agreements, including the (a) the Services Agreement by and among the Partnership, the General Partner, QRE Operating, LLC and Quantum Resources Management, LLC (“QRM”) dated December 22, 2010, (b) the Omnibus Agreement by and among the Partnership, General Partner, the Fund, QA Holdings, LP and QA Global GP, LLC, dated December 22, 2010 and (c) the Stakeholders’Agreement by and among the Partnership and the Fund, dated as of September 29, 2010.
	Simultaneously with the execution of the Merger Agreement, Breitburn, the Fund and the QR Parties entered into a Registration Rights Agreement (the “Registration Rights Agreement”) dated as of July 23, 2014 and effective as of the Closing Date. Among other things, pursuant to the Registration Rights Agreement, (i) no later than the 90th day following the Closing Date, Breitburn will file a shelf registration statement with the SEC to permit the public resale of the Breitburn Units received by the Fund and QR Parties as Unit Consideration, (ii) the Fund and QR Parties will have the right to participate in future underwritten public offerings of Breitburn Units and (iii) to initiate an underwritten offering of the Breitburn Units received by the Fund and QR Parties as Unit Consideration, subject to certain conditions.
	On October 17, 2014, we announced a special meeting of unitholders in connection with the proposed merger with Breitburn on November 18, 2014. At the special meeting, our unitholders will meet for the following purposes (i) to consider and vote on the adoption of the Merger Agreement; (ii) to consider and vote on an advisory, non-binding basis to approve the merger-related compensation payments that may become payable to the Partnership’s named executive officers in connection with the merger; and (iii) to approve the adjournment of the special meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes to adopt the merger agreement at the time of the special meeting. See Note 21 – Subsequent Events.
	As of September 30, 2014, our ownership structure comprised a 7.5% limited partner interest in us represented by 6,133,558 Class B units held by our affiliates and former owners of QRE GP, a 29.2% limited partner interest held by the Fund, comprised of common units and all of our preferred units, and a 63.3% limited partner interest held by the public unitholders.

Summary Of Significant Accounting Policies	'
	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation and Principles of Consolidation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“U.S. GAAP”) for complete annual financial statements. During interim periods, the Partnership follows the accounting policies disclosed in its Annual Report on Form 10-K for the year ended December 31, 2013 (“2013 Annual Report”), filed with the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements for the three and nine months ended September 30, 2014 and 2013 include all adjustments we believe are necessary for a fair statement of the results for the interim periods. The unaudited consolidated financial statements include the accounts of the Partnership, its 100% owned subsidiaries, and investments we are deemed to control. All significant intercompany transactions have been eliminated upon consolidation. Prior period amounts have been revised to conform to current period presentation. Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2014. These unaudited consolidated financial statements and other information included in this quarterly report should be read in conjunction with our consolidated financial statements and notes thereto included in our 2013 Annual Report.
	Accounting Policy Updates
	The accounting policies followed by the Partnership are set forth in Note 2 – Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in our 2013 Annual Report. The following addition to our policies was made during the nine months ended September 30, 2014 to give effect to the GP Buyout Transaction.
	Deferred Class B Unit Obligation
	Our deferred class B units obligation is classified as a non-current liability and is remeasured each reporting period based on the fair value of the liability. Accordingly, any changes in fair value are included in earnings and reported as a component of Other income, net within our consolidated statement of operations. See Note 11 – Deferred Class B Unit Obligation.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers: Topic 606. The objective of this update is to provide guidance on how 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 update is prospective and is effective for interim and annual periods beginning after December 15, 2016. Early adoption is not permitted. We are evaluating the potential impacts this ASU will have on our financial statements and disclosures.
	In June 2014, the FASB issued ASU 2014-12, Compensation – Stock Compensation: Topic 718. The amendments within this update require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with earlier adoption permitted. We are evaluating the potential impacts this ASU will have on our financial statements and disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern. The new going concern standard codifies in U.S. GAAP management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. This ASU is effective for interim and annual periods beginning on or after December 15, 2016 and early adoption is permitted. We do not expect the adoption of this guidance to have a material impact our financial statements and disclosures.

	NOTE 3 – ACQUISITIONS
	2014 Acquisitions
	During 2014, we closed several small acquisitions of oil and natural gas properties located in East Texas from private sellers for an aggregate purchase price of $47.9 million in cash, subject to customary purchase price adjustments, using funds drawn on our revolving credit facility.
	2013 Acquisition
	On August 6, 2013, we closed the acquisition of primarily oil properties located in East Texas (the “2013 East Texas Acquisition”) from a private seller for $108.2 million cash, subject to customary purchase price adjustments using funds drawn on our revolving credit facility. The acquisition had an effective date of June 1, 2013. The acquisition costs associated with the 2013 East Texas Acquisition were $0.4 million. In connection with the 2013 East Texas Acquisition, we assumed an estimated regulatory remediation liability of $0.5 million. Refer to Note 12 – Commitments and Contingencies for further details.
	In connection with the 2013 East Texas Acquisition, we also acquired a  32% interest in ETSWDC giving us control of ETSWDC as we previously owned 24%.  As of the closing date of the 2013 East Texas Acquisition, we consolidated ETSWDC into our consolidated financial statements. As a result of consolidation, our previous ownership in ETSWDC was remeasured to fair value on the acquisition date resulting in a gain of $1.3 million recognized in the third quarter of 2013. During the fourth quarter 2013, we acquired an additional 3% from another seller giving us an aggregate 59% ownership interest as of March 31, 2014.
	The 2013 East Texas Acquisition qualified as a business combination and was accounted for under the purchase method of accounting. The fair value measurements of the oil and gas properties, the investment in ETSWDC, and asset retirement obligations were measured using valuation techniques and unobservable inputs that convert future cash flows to a single discounted amount.
	The following table summarizes the final fair values of the assets acquired and liabilities assumed as of the closing date:
	Oil and gas properties		$	105,751
	Investment in ETSWDC			9,576
	Asset retirement obligation			-6,069
	Other current liabilities			-1,044
	Net assets acquired		$	108,214

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	NOTE 5 – FAIR VALUE MEASUREMENTS
	Our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, are carried at cost, which approximates fair value due to the short-term maturity of these instruments. Our other financial and non-financial assets and liabilities that are being measured on a recurring basis are measured and reported at fair value.
	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 the measurement date (exit price). U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of fair value hierarchy are as follows:
	Level 1 – Defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities.
	Level 2 – Defined as inputs other than quoted prices in active markets that are either directly or indirectly observable for the asset or liability.
	Level 3 – Defined as unobservable inputs for use when little or no market data exists, therefore requires an entity to develop its own assumptions for the asset or liability.
	Commodity Derivative Instruments — The fair value of the commodity derivative instruments is estimated using a combined income and market valuation methodology based upon observable forward commodity price and volatility curves. The curves are obtained from independent pricing services. We validate the data provided by independent pricing services by comparing such pricing against other third party pricing data.
	Interest Rate Derivative Instruments — The fair value of the interest rate derivative instruments is estimated using a combined income and market valuation methodology based upon observable forward interest rates and volatility curves. The curves are obtained from independent pricing services. We validate the data provided by independent pricing services by comparing such pricing against other third party pricing data.
	Available for Sale Securities — The fair value of the available-for-sale securities are estimated using actual trade data, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, independent pricing vendors, or other sources. We validate the data provided by independent pricing services to make assessments and determinations as to the ultimate valuation of its investment portfolio by comparing such pricing against other third party pricing data.
	Deferred Class B Unit Obligation — The Deferred Class B Unit Obligation represents consideration for the GP Buyout. The fair value of the deferred Class B unit obligation as of September 30, 2014 is based on the weighted average probability of the obligation being achieved based on: (i) the reduced number of units contemplated in the Merger Agreement using quoted market prices as of September 30, 2014, which value is subject to future market price fluctuations, and (ii) the previously applied methodology using a Monte-Carlo valuation model based on the existing terms of the deferred Class B unit obligation.  The previously applied methodology estimates the value using a combination of quoted market prices and the probability of achieving operating performance related to (a) the distribution rate, (b) Distribution Coverage Ratio (as defined in our Partnership Agreement), and (c) Total Debt to EBITDAX (as defined in our Partnership Agreement) (collectively “the Class B Criteria”). The Class B Criteria represent significant unobservable inputs.
	We utilize the most observable inputs available for the valuation technique utilized. The financial assets and liabilities are classified in their entirety based on the lowest level of input that is of significance to the fair value measurement. The following table sets forth, by level within the hierarchy, the fair value of our financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2014 and December 31, 2013. All fair values reflected below have been adjusted for nonperformance risk.

There were no Level 3 instruments for the nine months ended September 30, 2013. The Level 3 instruments presented in the table consists of the entitlement our former general partner owners have to receive up to an aggregate of 11.6 million Class B units.

	Gain on deferred Class B unit obligation attributable to the change in fair value still held at the end of the period	$	-6,883
	The fair value of the Level 3 deferred Class B unit obligation has been determined using available market information and commonly accepted valuation methodologies, as described above. The key assumptions of the valuation model consist of performance criteria as described in Note 13 – Partners’ Capital and include EBITDA volatility of 20% and equity volatility at 30%. Considerable judgment is required in interpreting the market data to develop the estimate of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of the obligation, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued since the period indicated above, and current estimates of fair value could differ significantly from the amounts presented.
	Fair Value of Other Financial Instruments
	Fair value guidance requires certain fair value disclosures, such as those on our long-term debt, to be presented in both interim and annual reports. The estimated fair value amounts of financial instruments have been determined using available market information and valuation methodologies described below.
	Revolving Credit Facility — The fair value of our revolving credit facility depends primarily on the current active market LIBOR. The carrying value of our revolving credit facility as of September 30, 2014 approximates fair value based on the current LIBOR and is classified as a Level 2 input in the fair value hierarchy.
	Derivative Premiums – The fair value of the deferred premiums on our commodity derivatives is based on the current active market LIBOR.  The carrying value of the premiums as of September 30, 2014 approximates fair value based on the current LIBOR and is classified as a Level 2 input in the fair value hierarchy.  Refer to Note 6 – Derivative Activities for further information on the derivative premiums.
	Senior Notes – The fair value of our senior notes is measured based on inputs from quoted, unadjusted prices from over-the-counter markets for debt instruments. If the senior notes had been measured at fair value, we would classify them as Level 1 under the fair value hierarchy. The fair value of our senior notes as of September 30, 2014 was $339.8 million.
	There have been no transfers between levels within the fair value measurement hierarchy during the nine months ended September 30, 2014.

Derivative Activities [Abstract]	'
Derivative Activities	'
	NOTE 6 – DERIVATIVE ACTIVITIES
	We have elected not to designate any of our derivatives as hedging instruments. As a result, these derivative instruments are marked to market at the end of each reporting period, and changes in the fair value of the derivatives are recorded as gains or losses in the consolidated statements of operations.
	Although we have the ability to elect to enter into netting agreements under our derivative instruments with certain of our counterparties, we have presented all asset and liability positions without netting. It is our policy to enter into derivative contracts, including interest rate swaps, only with counterparties that are creditworthy financial institutions deemed by management as competent and competitive market makers.  We do not post collateral under any of these contracts as they are secured under our credit facility.
	Commodity Derivatives
	Our business activities expose us to risks associated with changes in the market price of oil, natural gas and natural gas liquids. As such, future earnings are subject to fluctuations due to changes in the market price of oil, natural gas and NGLs. We use derivatives to reduce our exposure to changes in the prices of oil and natural gas. Our policies do not permit the use of derivatives for speculative purposes.
	During the nine months ended September 30, 2014, we did not enter into any new oil swap and basis swap contracts. All existing contracts were entered into with the counterparties under our revolving credit facility.
	The deferred premiums associated with certain of our oil and natural gas derivative instruments were $0.1 million and $5.0 million and are classified as accrued and other liabilities and other non-current liabilities, respectively, on the consolidated balance sheet as of September 30, 2014. The  deferred premiums associated with certain of our oil and natural gas derivative instruments were zero and $5.0 million and are classified as accrued and other liabilities and other non-current liabilities, respectively, on the consolidated balance sheet as of December 31, 2013. These deferred premiums will be paid to the counterparty with each monthly settlement (January 2015 – December 2017)  and will be recognized as an adjustment of gain (loss) on commodity derivative contracts, net.
	We hold commodity derivative contracts to manage our exposure to changes in the price of oil and natural gas related to our oil and natural gas production.  As of September 30, 2014, the notional volumes of our commodity derivative contracts were:

	Interest Rate Derivatives
	In an effort to mitigate exposure to changes in market interest rates, we have entered into interest rate swaps that effectively fix the LIBOR component on our outstanding variable rate debt.  The changes in the fair value of these instruments are recorded in current earnings.
	During the nine months ended September 30, 2014, we did not enter into any new interest rate swaps. All existing contracts were entered into with various financial institutions.

	Revolving Credit Facility
	On December 22, 2010, the Partnership entered into a Credit Agreement along with QRE GP, OLLC as Borrower, and a syndicate of banks (the “Credit Agreement”).
	Effective March 2, 2014, we entered into the sixth amendment to the Credit Agreement, which permitted the GP Buyout Transaction and provides for the exclusion of QRE GP as a guarantor of our credit facility.
	Effective April 21, 2014, we entered into the seventh amendment to the Credit Agreement, which reduced the borrowing base from $950 million to $900 million.
	As of September 30, 2014, we had $755.0 million of borrowings outstanding with borrowing availability of $121.5 million ($900.0 million of borrowing base less $755.0 million of outstanding borrowing and $23.5 million of letters of credit) under the Credit Agreement, which availability is limited to $55.0 million due to our total debt to EBITDAX (as such term is defined in the Credit Agreement) and $70.0 million due to the Merger Agreement.
	As of September 30, 2014, the Credit Agreement provided for a $1.5 billion revolving credit facility maturing on April 20, 2017, with a borrowing base of $900.0 million. The borrowing base is subject to redetermination on a semi-annual basis as of May 1 and November 1 of each year and is subject to a number of factors including quantities of proved oil and natural gas reserves, the banks’ pricing assumptions, and other various factors unique to each member bank. The November 1, 2014 borrowing base redetermination has been deferred pending the completion of the Merger. The borrowing base may also be reduced by an amount equal to 0.25 multiplied by the stated principal amount of any issuances of senior notes. Borrowings under the Credit Agreement are collateralized by liens on at least 80% of our oil and natural gas properties and all of our equity interests in OLLC and any future guarantor subsidiaries.  ETSWDC and QRE GP are not subsidiary guarantors under our Credit Agreement.  Borrowings bear interest at our option of either (i) the greater of the prime rate of Wells Fargo Bank, National Association, the federal funds effective rate plus 0.50%, or the one-month adjusted LIBOR plus 1.0%, all of which would be subject to a margin that varies from 0.50% to 1.50% per annum according to the borrowing base usage (which is the ratio of outstanding borrowings and letters of credit to the borrowing base then in effect), or (ii) the applicable LIBOR plus a margin that varies from 1.50% to 2.50% per annum according to the borrowing base usage. The unused portion of the borrowing base is subject to a commitment fee that varies from 0.375% to 0.50% per annum.
	The Credit Agreement requires us to maintain a ratio of total debt to EBITDAX (as such term is defined in the Credit Agreement) of not more than 4.0 to 1.0 and a current ratio (as such term is defined in the Credit Agreement) of not less than 1.0 to 1.0. Additionally, the Credit Agreement contains various covenants and restrictive provisions which limit our ability to incur additional debt, guarantees or liens; consolidate, merge or transfer all or substantially all of our assets; make certain investments, acquisitions or other restricted payments; modify certain material agreements; engage in certain types of transactions with affiliates; dispose of assets; prepay certain indebtedness; and also requires us to provide audited financial statements within 90 days of year end and quarterly unaudited financial statements within 45 days of quarter end. The Credit Agreement also prohibits us from entering into commodity derivative contracts covering, in any given year, in excess of the greater of (i) 90% of our forecasted production attributable to proved developed producing reserves and (ii) 85% of our forecasted production for the next two years from total proved reserves and 75% of our forecasted production from total proved reserves thereafter, in each case, based upon production estimates in the most recent reserve report. If we fail to perform our obligations under these and other covenants, the revolving credit commitments may be terminated and any outstanding indebtedness under the Credit Agreement, together with accrued interest, could be declared immediately due and payable. As of September 30, 2014, we were in compliance with all of the Credit Agreement covenants.
	As of November 4, 2014 we had $770 million of borrowings outstanding with borrowing availability of $106.5 million ($900 million of borrowing base less $770 million of outstanding borrowing and $23.5 million of outstanding letters of credit) under the Credit Agreement, which availability is limited to $40.0 million due to our total debt to EBITDAX (as such term is defined in the Credit Agreement) and $55.0 million due to the Merger Agreement.
	9.25% Senior Notes
	On July 30, 2012, we and our 100%  owned subsidiary QRE FC, completed a private placement offering to eligible purchasers of an aggregate principal amount of $300 million of 9.25% Senior Notes, due 2020 (the “Senior Notes”). The Senior Notes were issued at 98.62% of par with interest payments to be made on February 1 and August 1 each year beginning in 2013.  In 2012, we filed and completed a registration statement with the SEC to allow the holders of the Senior Notes to exchange for registered Senior Notes that have substantially identical terms as the Senior Notes. We have the option to redeem the notes, in whole or in part, at any time on or after August 1, 2016, at the specified redemption prices together with any accrued and unpaid interest to the date of redemption, except as otherwise described below. Prior to August 1, 2016, we may redeem all or any part of the notes at the “make-whole” redemption price. In addition, prior to August 1, 2015, we may at our option, redeem up to 35% of the aggregate principal amount of the notes at the redemption price with the net proceeds of a public or private equity offering. We may be required to offer to repurchase the Senior Notes at a purchase price of 101% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, in the event of a change of control as defined by the indenture. Our and QRE FC’s obligations under the Senior Notes are guaranteed by OLLC. In the future, the guarantees may be released or terminated under the following circumstances: (i) in connection with any sale or other disposition of all or substantially all of the properties of the guarantor; (ii) in connection with any sale or other disposition of sufficient capital stock of the guarantor so that it no longer qualifies as our Restricted Subsidiary (as defined in the indenture); (iii) if designated to be an unrestricted subsidiary; (iv) upon legal defeasance, covenant defeasance or satisfaction and discharge of the indenture; (v) upon the liquidation of the guarantor provided no default or event of default has occurred or is occurring; (vi) at such time the guarantor does not have outstanding guarantees of our, or any other guarantor’s, other, debt; or (vii) upon merging into, or transferring all of its properties to us or another guarantor and ceasing to exist. Refer to Note 20 – Subsidiary Guarantors for further details of our guarantors.
	The indenture governing the Senior Notes (the “Indenture”) restricts our ability and the ability of certain of our subsidiaries to: (i) incur additional debt or enter into sale-leaseback transactions; (ii) pay distributions on, or repurchase, equity interests; (iii) make certain investments; (iv) incur liens; (v) enter into transactions with affiliates; (vi) merge or consolidate with another company; and (vii) transfer and sell assets. These covenants are subject to a number of important exceptions and qualifications. If at any time when the Senior Notes are rated investment grade by each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no Default (as defined in the Indenture) has occurred and is continuing, many of such covenants will terminate and we and our subsidiaries will cease to be subject to such covenants.  The Indenture also includes customary events of default. As of September 30, 2014, we were in compliance with all financial and other covenants of the Senior Notes.

Commitments And Contingencies	'
	NOTE 12 – COMMITMENTS AND CONTINGENCIES
	Property Reclamation Deposit
	As of September 30, 2014 and December 31, 2013, $10.7 million is recorded in other assets on the consolidated balance sheets related a property reclamation deposit with ExxonMobil Corporation (the “Seller”). We are required to maintain the escrow account in effect for three years after all abandonment and remediation obligations have been completed. The funds in the escrow account are not to be returned to us until the later of three years after satisfaction of all abandonment obligations or December 31, 2026.  At certain dates subsequent to closing, we have the right to request a refund of a portion or all of the property reclamation deposit. Granting of the request is at the Seller’s sole discretion. In addition to the cash deposit, a letter of credit of $23.4 million is required in favor of the Seller.
	NPI Obligation
	As a part of our acquisition of certain oil producing properties from the Fund in December 2012, we assumed a net profit interest (“NPI”) related to the Jay field.  Under the arrangement, the NPI is payable after: (i) funds are withheld, to the extent allowable each month under the arrangement, to pay for the NPI holder’s share of future development costs and abandonment obligations, and (ii) we are reimbursed for the NPI holder’s share of excess historical productions costs.  Once the NPI holder’s share of the excess historical costs is reimbursed, the NPI will be payable monthly to the extent the NPI for that month exceeds amount withheld for that month for future development costs and abandonment obligations.  The NPI holder’s share of excess historical production costs amounted to $0.7 million and $2.9 million as of September 30, 2014 and December 31, 2013, respectively.  In addition, we will retain the NPI holder’s share of future development costs and abandonment obligations, subject to future production, production costs, and capital spending level,  which will be paid using the funds withheld.  The NPI holder’s share along with our share of the abandonment costs is reflected in our asset retirement obligations as of September 30, 2014 and December 31, 2013.
	Under the arrangement, the Partnership has the option to deposit into a separate account the funds withheld from the NPI holder for their portion of the future development costs and abandonment obligations. The account for these funds was established in the second quarter of 2014 and the balance of such account as of September 30, 2014 was $18.3 million which was recorded in other assets.
	Lease Guarantees
	The Fund has entered into various lease contracts that can routinely extend beyond five years which list the Partnership as a guarantor. In December 2012, we were named guarantor for QRM’s office lease in Houston, Texas with an approximate value of $26.8 million that terminates in 2022.  As of September 30, 2014 and December 31, 2013, the approximate value of this guarantee was $22.3 million and $24.2 million, respectively.
	Legal Proceedings
	In the ordinary course of business, we are involved in various legal proceedings. To the extent we are able to assess the likelihood of a negative outcome for these proceedings, our assessments of such likelihood range from remote to probable. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, we accrue the estimated amount.  We currently have no legal proceedings with a probable adverse outcome. Therefore, we do not believe that the outcome of these legal proceedings, individually or in the aggregate, will have a materially adverse effect on our financial condition, results of operations or cash flows.
	Litigation
	Following the July 24, 2014 announcement that the Partnership and Breitburn had entered into a definitive merger agreement, purported unitholders of the Partnership filed putative class action lawsuits, on behalf of the common unitholders of the Partnership, asserting claims challenging the Merger. Four purported class action lawsuits were filed in the United States District Court for the Southern District of Texas and were consolidated under the caption In re QR Energy LP Unitholder Litigation, No. 4:14-cv-02195 (the “Consolidated Unitholder Action”). Plaintiffs in the Consolidated Unitholder Action bring claims against the Partnership, our general partner, the members of our general partner’s board of directors, Breitburn, Breitburn GP and Merger Sub.
	Plaintiffs in the Consolidated Unitholder Action each allege that the director defendants breached their fiduciary duties of loyalty, due care, good faith, and independence owed to the Partnership’s unitholders by allegedly approving the Merger Agreement at an unfair price and through an unfair process. Plaintiffs in the Consolidated Unitholder Action specifically allege that the director defendants failed to maximize the value of the Partnership and took steps to avoid competitive bidding, failed to properly value the Partnership, acted in bad faith and for improper motives, and ignored or failed to protect against numerous conflicts of interest arising out of the Merger. The plaintiffs further allege that Breitburn, Breitburn GP and Merger Sub aided and abetted the alleged breaches of fiduciary duties by the director defendants.
	Plaintiffs in the Consolidated Unitholder Action further allege that the named defendants violated Section 14(a), and SEC Rule 14a-9 promulgated thereunder, and Section 20(a) of the Securities Exchange Act of 1934 by disseminating a false and materially misleading proxy statement in connection with the Merger.
	Plaintiffs in the Consolidated Unitholder Action seek, among other relief, to enjoin the Merger, rescission in the event the Merger is consummated, an order directing defendants to account to plaintiffs and other members of the putative class for all damages caused by their alleged breaches, and an award of costs and disbursements, including reasonable attorneys’ and experts’ fees.
	In addition, on October 3, 2014, the LL&E Royalty Trust (the “Trust”) filed a lawsuit in the United States District Court for the Eastern District of Michigan against QRM, the Partnership and QRE Operating, LLC claiming that the defendants illegally and fraudulently failed to pay the Trust royalties to which it was contractually entitled, under the NPI obligation related to the Jay field, as discussed above, from a certain oil producing property. The Trust also claimed that the defendants fraudulently manipulated oil production and production costs to drive down the value of the Trust’s interest in the royalties in an attempt to purchase the Trust’s interest at an artificially low price. The Trust seeks, among other relief, monetary damages of at least $18 million, plus interest, attorney fees and costs, statutory treble damages, and an order requiring the defendants to begin making monthly royalty payments to the Trust. The Trust also seeks an order enjoining the Merger until QRM has complied with its obligations to pay royalties to the Trust.
	Each of the lawsuits described above is at a preliminary stage. The Partnership’s management cannot predict the outcome of these or any other lawsuit that might be filed, nor can it predict the amount of time and expense that will be required to resolve these or other lawsuits. The Partnership’s management believes these lawsuits are without merit and intends to defend against them vigorously.
	Regulatory Remediation Contingencies
	As of September 30, 2014 and December 31, 2013, we had approximately $0.3 million and $2.3 million, respectively, in regulatory remediation liabilities related to the acquisitions of oil and natural gas properties. This is management’s best estimate of the costs for remediation and restoration with respect to these regulatory remediation matters, although the ultimate cost could vary. The regulatory remediation liability is recorded in the other liabilities caption on the consolidated balance sheet.

	As a result of the GP Buyout Transaction, see Note 1 – Organization and Operations, the limited liability company interest of the general partner was contributed to the Partnership.
	On March 3, 2014, we filed a prospectus supplement establishing an at-the-market equity program under which we may sell common units with an aggregate offering price up to $100 million, from time to time, until the expiration of our shelf filing in June 2015. As of September 30, 2014, no common units have been issued under the program.
	On January 14, 2014, we filed an automatic registration statement on Form S-3 with the SEC to register our common units, preferred units and our debt securities, which may be co-issued by QRE FC. The registration statement also registered guarantees of debt securities by OLLC.
	Class B Units
	As of September 30, 2014, the QR Parties own a 7.5% limited partnership interest in us, represented by 6,133,558 Class B units. The Class B units are immediately convertible into common units at the election of the QR Parties. Class B units have all the rights of common units except for the right to vote on matters requiring specific approval by common unitholders, and are allocated income in an amount that is equal to their distributions.
	Pursuant to the GP Buyout Transaction completed on March 2, 2014, the QR Parties are entitled to receive up to an aggregate of 11.6 million Class B units in up to four annual installments during the next six calendar years, beginning with respect to the year ending December 31, 2014. The QR Parties are entitled to receive an annual installment of such units with respect to any calendar year in which we pay a distribution of $0.4744 per unit with respect to each quarter, achieved a Distribution Coverage Ratio (as defined in our Partnership Agreement) for the year of at least 1.0 and achieve a Total Debt to EBITDAX (as defined in our Partnership Agreement) of no greater than 4.0 for each quarter during such year, unless any excess has been approved by the conflicts committee of our general partner. The Class B units have the same rights, preferences and privileges of our common units and are entitled to the same cash distributions per unit as our common units, except in liquidation where distributions are made in accordance with the respective capital accounts of the units and are convertible into an equal number of common units at the election of the holder. These Class B units may be issued as incentives without any corresponding increase in the cash distributions we pay to our unitholders, and any such Class B units issued to the QR Parties will not be subject to forfeiture should we fail to meet the issuance criteria in future periods.
	Pursuant to the Merger Agreement with Breitburn dated July 23, 2014, the number of Class B units issuable to the QR Parties upon a change of control of the Partnership will be equal to (i) 6,748,067, minus (ii) the excess of (A) the number of performance units that vest and are settled in common units of the Partnership in connection with the Merger over (B) 383,900 and will be issued and treated as outstanding Class B units and converted into the right to receive the Unit Consideration.
	Simultaneously with the execution of the Merger Agreement, the Partnership entered into letter agreements with each of the QR Parties, each of which provides for the waiver by the respective QR Parties of its right to receive a portion of the Class B units to which it would otherwise be entitled as a result of the immediate vesting of certain Contingent Class B Units upon a Change of Control (as defined in our Partnership Agreement).
	On February 22, 2013, our general partner elected to convert 80% of its fourth quarter 2012 management incentive fee and, on March 4, 2013, received 6,133,558 Class B units which were issued and outstanding upon conversion. As a result, in the first quarter 2013 our general partner received a reduced fourth quarter management incentive fee of $0.7 million and a distribution of $3.0 million on the Class B units related to the fourth quarter 2012.
	Allocation of Net Income (Loss)
	Net income (loss) is reduced by noncontrolling interest and is then allocated to the preferred and Class B unitholders to the extent distributions are made or accrued to them during the period and, for 2013, to QRE GP to the extent of the management incentive fee. The remaining income is allocated between QRE GP and the common unitholders in proportion to their pro rata ownership during the period. Subsequent to the GP Buyout Transaction on March 2, 2014, net income (loss) is not allocated to QRE GP.
	Cash Distributions
	Our partnership agreement, as amended, requires that within 45 days after the end of each quarter, or at the discretion of the general partner, in three equal installments within 15,  45, and 75 days following the end of each quarter, we distribute all of our available cash to preferred unitholders, in arrears, and common unitholders of record on the applicable record date, as determined by our general partner’s Board of Directors.
	The following sets forth the distributions that have been declared and paid or are payable:

		-1		For the three and nine months ended September 30, 2014 and 2013, we had weighted average preferred units outstanding of 16,666,667. The preferred and Class B units are contingently convertible into common units and could potentially dilute earnings per unit in the future. Upon issuance, 11.6 million of deferred Class B units would also be convertible into common units and could potentially dilute earnings per unit in the future. For the three months ended September 30, 2014, the preferred, the deferred Class B, and the Class B units have been included in the diluted earnings per unit calculation as they were dilutive for the period, however were not included in the nine months ended September 30, 2014 diluted earnings per unit calculation as they were anti-dilutive for the period. The preferred and Class B units have not been included in the diluted earnings per unit calculation for the three and nine months ended September 30, 2013 as they were anti-dilutive for the period.
	Net income (loss) per limited partner unit is determined by dividing the net income (loss) available to the limited partner, after deducting QRE GP’s interest in net income (loss) through the date of the GP Buyout Transaction, by the weighted average number of limited partner units outstanding during the three and nine months ended September 30, 2014 and 2013.

Unit-Based Compensation [Abstract]	'
Unit-Based Compensation	'
	NOTE 16 – UNIT-BASED COMPENSATION
	The QRE GP, LLC Long-Term Incentive Plan (the “Plan”) was established for employees, officers, consultants and directors of the Partnership and its affiliates, including QRM, who perform services for us. The Plan consists of unit options, restricted units, phantom units, unit appreciation rights, distribution equivalent rights, other unit-based awards and unit awards. The purpose of awards under the Plan is to provide additional incentive compensation to such individuals providing services to us and to align the economic interests of such individuals with the interests of our unitholders. The Plan limits the number of common units that may be delivered pursuant to awards under the Plan to 1.8 million units.
	On March 10, 2014, we held a special meeting of our common unitholders at which our common unitholders approved the First Amendment to the QRE GP, LLC Long-Term Incentive Plan (the “Amended LTIP”). The Amended LTIP increases the number of common units available for delivery with respect to awards under the Plan so that, an additional 3 million common units are available for delivery with respect to awards under the Amended LTIP.
	Restricted Units
	Periodically we issue restricted units with a service condition (“Restricted Units”) and restricted units with a market condition (“Performance Units”). The fair value of the Restricted Units, based on the closing price of our common units at the grant date, is amortized to compensation expense on a straight-line basis over the vesting period of the award. The fair value of the Performance Units, based on a Monte Carlo model with assumptions based on market conditions, is amortized to compensation expense on a straight-line basis over the vesting period of the award.
	On April 22, 2013, we granted approximately 455,000 Restricted Unit awards and approximately 149,000 Performance Unit awards to employees of QRM and approximately 20,000 unit awards to independent directors of the Partnership.
	On April 10, 2014, we granted approximately 550,000 Restricted Unit awards and approximately 135,000 Performance Unit awards to employees of QRM and approximately 20,000 unit awards to independent directors of the Partnership.
	Service Restricted Units
	For the three months ended September 30, 2014 and 2013, we recognized compensation expense related to the outstanding Restricted Units of $2.0 million and $1.7 million. For the nine months ended September 30, 2014 and 2013, we recognized compensation expense related to the outstanding Restricted Units of $4.6 million and $4.6 million.
	Performance Restricted Units
	The Performance Units will be earned over a three year period based on the Partnership’s performance relative to its peers in accordance with the Plan. The final units to be issued will range from 0 – 225% of the initial units granted. For the three months ended September 30, 2014 and 2013, we recognized $0.4 million and $0.2 million of compensation expense related to the Performance Units. For the nine months ended September 30, 2014 and 2013, we recognized $1.2 million and $0.5 million of compensation expense related to the Performance Units.
	The following table summarizes the activity of our Restricted Units and Performance Units for the nine months ended September 30, 2014:
			Weighted			Weighted
			Average			Average
		Number of	Grant-Date		Number of	Grant-Date
		Service Restricted units	Fair Value		Performance units	Fair Value

	Pursuant to the Merger Agreement with Breitburn dated July 23, 2014, each restricted Restricted Unit that is outstanding pursuant to the Partnership’s long-term incentive plan will vest upon the Effective Time and be converted into the right to receive the Unit Consideration.  Additionally, immediately prior to the Effective Time each Performance Unit granted pursuant to the Partnership’s long-term incentive plan will vest and be settled with respect to the number of common units issuable determined based on actual attainment of the applicable performance goal(s) as of two business days prior to the Effective Time, with such resulting common units converted at the Effective Time into the right to receive the Unit Consideration.

	NOTE 18 – RELATED PARTY TRANSACTIONS
	Ownership in QRE GP by the Management of the Fund and its Affiliates
	Through March 2, 2014, affiliates of the Fund owned 100% of QRE GP. As of September 30, 2014, the Fund owned an aggregate 29.2%  limited partner interest in us represented by all of our Class C preferred units and 7,145,866 common units. In addition, former owners of QRE GP owned a  7.5% limited partner interest in us, represented by 6,133,558 Class B units.
	Class C Agreement
	Simultaneously with the execution of the definitive merger agreement with Breitburn, the Partnership entered into an agreement with the Fund parties which provides that, until the earlier of the consummation of the merger or the termination of the merger agreement with Breitburn in accordance with its terms, each Fund party will not convert the Class C units held by such Fund party into common units pursuant to such Fund party’s conversion rights under Section 5.12(b)(vii) of our Partnership Agreement. In addition, each Fund party agreed not to sell, transfer, assign, tender in any tender or exchange offer, pledge, encumber, hypothecate or dispose of, or to enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, pledge, lien, hypothecation or other disposition of any Class C units.
	Contracts with the Former Owners of QRE GP and its Affiliates
	We have entered into agreements with the former owners of QRE GP and its affiliates. The following is a description of the activity of those agreements.
	Services Agreement
	QRM provides management and operational services for us and the Fund. In accordance with the Services Agreement, QRM is entitled to the reimbursement of general and administrative expenses based on the allocation of charges to us based on the estimated use of such services between us and the Fund. The reimbursement includes direct expenses plus an allocation of compensation costs based on employee time expended and other indirect expenses based on multiple operating metrics. If our sponsor raises additional funds in the future, the quarterly allocated costs will be further divided to include the sponsor’s additional funds as well. These fees will be included in general and administrative expenses in our consolidated statement of operations. QRM will have discretion to determine in good faith the proper allocation of the charges pursuant to the Services Agreement. Management believes this allocation methodology is a reasonable method of allocating general and administrative expenses between us and the Fund and provides for a reasonably accurate depiction of what our general and administrative expenses would be on a stand-alone basis without affiliations with the Fund or QRM. In connection with the execution of the Merger Agreement with Breitburn on July 23, 2014 the Services Agreement, upon closing of the merger, will be terminated as of the closing of the Merger.
	For the three months ended September 30, 2014 and 2013 we were charged $7.6 million and $9.0 million in allocated general and administrative expenses from QRM. For the nine months ended September 30, 2014 and 2013, we were charged $22.6 million and $25.1 million in allocated general and administrative expenses from QRM.
	In connection with the management of our business, QRM provides services for invoicing and collection of our revenues as well as processing of payments to our vendors. Periodically, QRM remits cash to us for the net working capital received on our behalf. Changes in the affiliate receivable balances during the nine months ended September 30, 2014 are included below:
	Net affiliate receivable as of December 31, 2013	$	3,915
	Revenues and other increases		355,043
	Expenditures		-283,029
	Settlements from the Fund		-76,816
	Net affiliate payable as of September 30, 2014	$	-887
	Management Incentive Fee
	Through March 2, 2014, under our partnership agreement, for each quarter for which we have paid distributions that equaled or exceeded 115% of our minimum quarterly distribution (which amount we refer to as our “Target Distribution”), or $0.4744 per unit, QRE GP was entitled to a quarterly management incentive fee subject to an adjusted operating surplus threshold as defined in the partnership agreement (“Adjusted Operating Surplus”). Pursuant to the GP Buyout Transaction completed on March 2, 2014 (see Note 1 – Organization and Operations), the management incentive fee was terminated effective for periods subsequent to December 31, 2013.
	For the nine months ended September 30, 2014, the management fee recognized was $1.4 million related to the fourth quarter of 2013. For the nine months ended September 30, 2013, the management incentive fee recognized was $2.0 million, consisting of $0.7 million related to the fourth quarter of 2012 and $1.3 million related to the second quarter 2013.  No management incentive fee was earned related to the first quarter 2013 due to the adjusted operating surplus limitation.
	On February 22, 2013, in accordance with our partnership agreement, our general partner elected to convert 80% of its fourth quarter 2012 management incentive fee and on March 4, 2013, received 6,133,558 Class B units which were issued and outstanding upon conversion. In exchange for the issuance of Class B units, management incentive fees payable in the future will, if earned, be reduced to the extent of this and any future conversions. As a result, our general partner received a reduced fourth quarter management incentive fee of $0.7 million and a distribution of $3.0 million on the Class B units related to the fourth quarter 2012.
	Waiver of Issuance of Contingent Class B Units
	Simultaneously with the execution of the definitive merger agreement with Breitburn on July 23, 2014, the Partnership entered into letter agreements with each of the QR Parties, each of which provides for the waiver by the respective QR Parties of its right to receive a portion of the Class B units to which it would otherwise be entitled as a result of the immediate vesting of certain Contingent Class B Units upon a Change of Control (as defined in our Partnership Agreement).
	Long–Term Incentive Plan
	The Plan provides compensation for employees, officers, consultants and directors of the Partnership and its affiliates, including QRM, who perform services for us. As of September 30, 2014 and December 31, 2013,  1,326,612 and 1,022,311 restricted units were outstanding under the Amended LTIP and Plan, respectively. For additional discussion regarding the Plan see Note 16 – Unit-Based Compensation.
	Distributions of Available Cash to Former Owners of QRE GP and Affiliates
	We generally make cash distributions to our common and affiliated common unitholders pro rata, including former owners of QRE GP and its affiliates. Refer to Note 13 – Partners’ Capital for details on the distributions.

Summary Of Significant Accounting Policies [Abstract]	'
Basis Of Presentation	'
	Basis of Presentation and Principles of Consolidation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“U.S. GAAP”) for complete annual financial statements. During interim periods, the Partnership follows the accounting policies disclosed in its Annual Report on Form 10-K for the year ended December 31, 2013 (“2013 Annual Report”), filed with the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements for the three and nine months ended September 30, 2014 and 2013 include all adjustments we believe are necessary for a fair statement of the results for the interim periods. The unaudited consolidated financial statements include the accounts of the Partnership, its 100% owned subsidiaries, and investments we are deemed to control. All significant intercompany transactions have been eliminated upon consolidation. Prior period amounts have been revised to conform to current period presentation. Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the full year ended December 31, 2014. These unaudited consolidated financial statements and other information included in this quarterly report should be read in conjunction with our consolidated financial statements and notes thereto included in our 2013 Annual Report.
Accounting Policy Updates/Revisions	'
	Accounting Policy Updates
	The accounting policies followed by the Partnership are set forth in Note 2 – Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in our 2013 Annual Report. The following addition to our policies was made during the nine months ended September 30, 2014 to give effect to the GP Buyout Transaction.
Deferred Class B Unit Obligation	'
	Deferred Class B Unit Obligation
	Our deferred class B units obligation is classified as a non-current liability and is remeasured each reporting period based on the fair value of the liability. Accordingly, any changes in fair value are included in earnings and reported as a component of Other income, net within our consolidated statement of operations. See Note 11 – Deferred Class B Unit Obligation.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers: Topic 606. The objective of this update is to provide guidance on how 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 update is prospective and is effective for interim and annual periods beginning after December 15, 2016. Early adoption is not permitted. We are evaluating the potential impacts this ASU will have on our financial statements and disclosures.
	In June 2014, the FASB issued ASU 2014-12, Compensation – Stock Compensation: Topic 718. The amendments within this update require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with earlier adoption permitted. We are evaluating the potential impacts this ASU will have on our financial statements and disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern. The new going concern standard codifies in U.S. GAAP management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. This ASU is effective for interim and annual periods beginning on or after December 15, 2016 and early adoption is permitted. We do not expect the adoption of this guidance to have a material impact our financial statements and disclosures.

The preferred and Class B units are contingently convertible into common units and could potentially dilute earnings per unit in the future. Upon issuance, 11.6 million of deferred Class B units would also be convertible into common units and could potentially dilute earnings per unit in the future. For the three months ended September 30, 2014, the preferred, the deferred Class B, and the Class B units have been included in the diluted earnings per unit calculation as they were dilutive for the period, however were not included in the nine months ended September 30, 2014 diluted earnings per unit calculation as they were anti-dilutive for the period. The preferred and Class B units have not been included in the diluted earnings per unit calculation for the three and nine months ended September 30, 2013 as they were anti-dilutive for the period.

Credit Agreement, interest rate description

'

'

'ETSWDC and QRE GP are not subsidiary guarantors under our Credit Agreement. Borrowings bear interest at our option of either (i) the greater of the prime rate of Wells Fargo Bank, National Association, the federal funds effective rate plus 0.50%, or the one-month adjusted LIBOR plus 1.0%, all of which would be subject to a margin that varies from 0.50% to 1.50% per annum according to the borrowing base usage (which is the ratio of outstanding borrowings and letters of credit to the borrowing base then in effect), or (ii) the applicable LIBOR plus a margin that varies from 1.50% to 2.50% per annum according to the borrowing base usage. The unused portion of the borrowing base is subject to a commitment fee that varies from 0.375% to 0.50% per annum.
