Partnership Operations and Organization [Abstract]
Partnership Operations and Organization	With the exception of per unit amounts, or as noted within the context of each disclosure, the dollar amounts presented in the tabular data within these disclosures are stated in millions of dollars. KEY REFERENCES USED IN THESE Unless the context requires otherwise, references to “we,” “us,” “our,” “Enterprise” or “Enterprise Products Partners” are intended to mean the business and operations of Enterprise Products Partners L.P. and its consolidated subsidiaries. References to “EPO” mean Enterprise Products Operating LLC, which is a wholly owned subsidiary of Enterprise, and its consolidated subsidiaries, through which Enterprise Products Partners L.P. conducts its business. Enterprise is managed by its general partner, Enterprise Products Holdings LLC (“Enterprise GP”), which is a wholly owned subsidiary of Dan Duncan LLC, a privately held Texas limited liability company. The membership interests of Dan Duncan LLC are owned by a voting trust, the current trustees (“DD LLC Trustees”) of which are: (i) Randa Duncan Williams, who is also a director and Chairman of the Board of Enterprise GP; (ii) Dr. Ralph S. Cunningham; and (iii) Richard H. Bachmann. Each of the DD LLC Trustees also currently serves as one of the three managers of Dan Duncan LLC. References to “EPCO” mean Enterprise Products Company, a privately held Texas corporation, and its privately held affiliates. A majority of the outstanding voting capital stock of EPCO is owned by a voting trust, the current trustees (“EPCO Trustees”) of which are: (i) Ms. Williams, who serves as Chairman of EPCO; (ii) Dr. Cunningham, who serves as a Vice Chairman of EPCO; and (iii) Mr. Bachmann, who serves as the President and Chief Executive Officer (“CEO”) of EPCO. Each of the EPCO Trustees is also a director of EPCO. In addition to owning our general partner, EPCO and its privately held affiliates owned approximately 34.4% of our limited partner interests at June 30, 2015. References to “Oiltanking” and “Oiltanking GP” mean Oiltanking Partners, L.P. and OTLP GP, LLC, the general partner of Oiltanking, respectively. In October 2014, we acquired approximately 65.9% of the limited partner interests of Oiltanking, all of the member interests of Oiltanking GP and the incentive distribution rights (“IDRs”) held by Oiltanking GP from Oiltanking Holding Americas, Inc. (“OTA”) as the first step of a two-step acquisition of Oiltanking. In February 2015, we completed the second step of this acquisition. See Note 11 for additional information regarding this acquisition. References to “TEPPCO” mean TEPPCO Partners, L.P. prior to its merger with one of our wholly owned subsidiaries in October 2009. References to “Offshore Gulf of Mexico Business” or “Offshore Business” refer to the operations we sold to Genesis Energy, L.P. (“Genesis”) in July 2015. See Note 6 for information regarding this sale. General We are a publicly traded Delaware limited partnership, the common units of which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “EPD.” We were formed in April 1998 to own and operate certain natural gas liquids (“NGLs”) related businesses of EPCO and are now a leading North American provider of midstream energy services to producers and consumers of natural gas, NGLs, crude oil, petrochemicals and refined products. Our integrated midstream energy asset network links producers of natural gas, NGLs and crude oil from some of the largest supply basins in the United States (“U.S.”), Canada and Gulf of Mexico with domestic consumers and international markets. Our midstream energy operations currently include: natural gas gathering, treating, processing, transportation and storage; NGL transportation, fractionation, storage, and import and export terminals (including liquefied petroleum gas or “LPG”); crude oil gathering, transportation, storage and terminals; petrochemical and refined products transportation, storage and terminals, and related services; and a marine transportation business that operates primarily on the U.S. inland and Intracoastal Waterway systems and in the Gulf of Mexico. Our assets currently include approximately 49,000 miles of onshore pipelines; 225 million barrels (“MMBbls”) of storage capacity for NGLs, petrochemicals, refined products and crude oil; and 14 billion cubic feet (“Bcf”) of natural gas storage capacity. Our historical operations are reported under five business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, (iv) Petrochemical & Refined Products Services and (v) Offshore Pipelines & Services. On July 24, 2015, we completed the sale of our Offshore Business to Genesis. The assets, liabilities and related noncontrolling interest attributable to this business were classified as held for sale at June 30, 2015 (see Note 6). As a result of this sale, we renamed our Onshore Crude Oil Pipelines & Services business segment “Crude Oil Pipelines & Services.” In addition, we renamed our Onshore Natural Gas Pipelines & Services business segment “Natural Gas Pipelines & Services.” The operations reported within these two onshore segments did not change due to these name changes. We will continue to report the historical results of the Offshore Pipelines & Services segment through the closing date of the sales transaction. See Note 12 for additional information regarding our business segments. See Note 18 for information regarding our recently completed acquisition of the member interests of EFS Midstream LLC. We conduct substantially all of our business through EPO and are owned 100% by our limited partners from an economic perspective. Enterprise GP manages our partnership and owns a non-economic general partner interest in us. We, Enterprise GP, EPCO and Dan Duncan LLC are affiliates under the collective common control of the DD LLC Trustees and the EPCO Trustees. Like many publicly traded partnerships, we have no employees. All of our management, administrative and operating functions are performed by employees of EPCO pursuant to an administrative services agreement (the “ASA”) or by other service providers. See Note 13 for information regarding the ASA and other related party matters. In August 2014, we completed a two-for-one common unit split. All per unit amounts and number of units outstanding presented in these Unaudited Condensed Consolidated Financial Statements and Notes thereto are on a post-split basis.

General Accounting Matters [Abstract]
General Accounting Matters	Our results of operations for the three and six months ended June 30, 2015 are not necessarily indicative of results expected for the full year of 2015. In our opinion, the accompanying Unaudited Condensed Consolidated Financial Statements include all adjustments consisting of normal recurring accruals necessary for fair presentation. Although we believe the disclosures in these financial statements are adequate and make the information presented not misleading, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These Unaudited Condensed Consolidated Financial Statements and Notes thereto should be read in conjunction with the Audited Consolidated Financial Statements and Notes thereto included in our annual report on Form 10-K for the year ended December 31, 2014 (the “2014 Form 10-K”) filed with the SEC on March 2, 2015. Contingencies Certain conditions may exist as of the date our consolidated financial statements are issued, which may result in a loss to us but which will only be resolved when one or more future events occur or fail to occur. Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the need for accounting recognition or disclosure of these contingencies, and such assessment inherently involves an exercise in judgment. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, our management and legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein. We accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when it is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, we disclose the nature of the contingency and, if feasible, an estimate of the possible loss or range of loss. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed. See Note 15 for additional information regarding our contingencies. Derivative Instruments We use derivative instruments such as futures, swaps, options, forward contracts and other arrangements to manage price risks associated with inventories, firm commitments, interest rates, foreign currencies and certain anticipated future commodity transactions. To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted. We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a monthly basis thereafter. Forecasted transactions are evaluated for the probability of occurrence and are periodically back-tested once the forecasted period has passed to determine whether similarly forecasted transactions are probable of occurring in the future. For certain physical forward commodity derivative contracts, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such contracts are not recognized in income. As a result, the revenues and expenses associated with such physical transactions are recognized during the period when volumes are physically delivered or received. Physical forward commodity contracts subject to this exception are evaluated for the probability of future delivery and are periodically back-tested once the forecasted period has passed to determine whether similar forward contracts are probable of physical delivery in the future. See Note 4 for additional information regarding our derivative instruments. Estimates Preparing our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates that affect amounts presented in the financial statements. Our most significant estimates relate to (i) the useful lives and depreciation/amortization methods used for fixed and identifiable intangible assets; (ii) measurement of fair value and projections used in impairment testing of fixed and intangible assets (including goodwill); (iii) contingencies; and (iv) revenue and expense accruals. Actual results could differ materially from our estimates. On an ongoing basis, we review our estimates based on currently available information. Any changes in the facts and circumstances underlying our estimates may require us to update such estimates, which could have a material impact on our consolidated financial statements. Income Taxes Provision for or benefit from income taxes primarily reflects our state tax obligations under the Revised Texas Franchise Tax (the “Texas Margin Tax”). For the three and six months ended June 30, 2015, we recognized a net income tax benefit of $7.9 million and $1.1 million, respectively, primarily due to certain legislative changes to the Texas Margin Tax enacted during the second quarter of 2015 that reduced the tax rate for business entities that operate within the state. For the three and six months ended June 30, 2014, we recognized net income tax expense of $10.0 million and $14.8 million, respectively. Restricted Cash Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products. Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or deposit requirements change. At June 30, 2015, our restricted cash amounts were $46.1 million. We did not have any restricted cash as of December 31, 2014. See Note 4 for information regarding our derivative instruments and hedging activities.

Equity-based Awards

Equity-based Awards	6 Months Ended

Equity-based Awards [Abstract]
Equity-based Awards	An allocated portion of the fair value of EPCO’s equity-based awards is charged to us under the ASA. The following table summarizes compensation expense we recognized in connection with equity-based awards for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Equity-classified awards: Restricted common unit awards $ 3.9 $ 9.0 $ 10.0 $ 20.6 Phantom unit awards 22.7 13.6 39.9 19.4 Liability-classified awards 0.1 0.2 0.2 0.3 Total $ 26.7 $ 22.8 $ 50.1 $ 40.3 The fair value of equity-classified awards is amortized into earnings over the requisite service or vesting period. Equity-classified awards are expected to result in the issuance of common units upon vesting. Compensation expense for liability-classified awards is recognized over the requisite service or vesting period based on the fair value of the award remeasured at each reporting date. Liability-classified awards are settled in cash upon vesting. At June 30, 2015, EPCO’s significant long-term incentive plans applicable to us were the Enterprise Products 1998 Long-Term Incentive Plan (“1998 Plan”) and the 2008 Enterprise Products Long-Term Incentive Plan (Third Amendment and Restatement) (“2008 Plan”). Up to 14,000,000 of our common units may be issued as awards under the 1998 Plan. The maximum number of common units available for issuance under the 2008 Plan was 30,000,000 at June 30, 2015. This amount will automatically increase under the terms of the 2008 Plan by 5,000,000 common units on January 1, 2016 and will continue to automatically increase annually on January 1 thereafter during the term of the 2008 Plan; provided, however, that in no event shall the maximum aggregate number exceed 70,000,000 common units. After giving effect to awards granted under the 1998 Plan and 2008 Plan through June 30, 2015, a total of 3,016,992 and 16,092,392 additional common units were available for issuance under these plans, respectively. Restricted Common Unit Awards Restricted common unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. Restricted common unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire. Restricted common units are included in the number of common units outstanding as presented on our Unaudited Condensed Consolidated Balance Sheets. The fair value of a restricted common unit award is based on the market price per unit of our common units on the date of grant. Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period. The following table presents information regarding restricted common unit awards for the period indicated: Number of Units Weighted- Average Grant Date Fair Value per Unit Restricted common units at December 31, 2014 4,229,790 $ 26.96 Vested (1,940,044 ) $ 25.96 Forfeited (111,250 ) $ 27.47 Restricted common units at June 30, 2015 2,178,496 $ 27.83 (1) Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued. Each recipient of a restricted common unit award is entitled to nonforfeitable cash distributions equal to the product of the number of restricted common units outstanding for the participant and the cash distribution per unit paid to our common unitholders. These distributions are included in “Cash distributions paid to limited partners” as presented on our Unaudited Condensed Statements of Consolidated Cash Flows. The following table presents supplemental information regarding our restricted common unit awards for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Cash distributions paid to restricted common unitholders $ 0.9 $ 1.6 $ 2.4 $ 4.1 Total intrinsic value of restricted common unit awards that vested during period 3.0 2.7 65.4 84.1 For the EPCO group of companies, the unrecognized compensation cost associated with restricted common unit awards was an aggregate $15.9 million at June 30, 2015, of which our allocated share of the cost is currently estimated to be $13.5 million. Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 1.2 years. Unit Option Awards EPCO’s long-term incentive plans provide for the issuance of non-qualified incentive options denominated in our common units. In general, unit option awards have a vesting period of four years from the date of grant and expire at the end of the calendar year following the year of vesting (e.g., an option vesting on May 29, 2014 will expire on December 31, 2015). However, unit option awards only become exercisable at certain times during the calendar year following the year in which they vest (typically the months of February, May, August and November). The following table presents unit option award activity for the period indicated: Number of Units Weighted- Average Strike Price (dollars/unit) Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value Unit option awards at December 31, 2014 1,270,000 $ 16.14 Exercised (1,060,000 ) $ 16.14 Unit option awards at June 30, 2015 210,000 $ 16.14 0.5 $ 2.9 (1) All of the unit option awards outstanding at June 30, 2015 were exercisable. None of the unit option awards outstanding at December 31, 2014 were exercisable. (2) Aggregate intrinsic value reflects fully vested unit option awards at the dates indicated. In order to fund its unit option award-related obligations, EPCO may purchase common units at fair value either in the open market or directly from us. When employees exercise unit option awards, we reimburse EPCO for the cash difference between the strike price paid by the employee and the actual purchase price paid by EPCO for the units issued to the employee. The following table presents supplemental information regarding unit option awards during the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Total intrinsic value of unit option awards exercised during period $ 2.2 $ 2.8 $ 19.6 $ 57.5 Cash received from EPCO in connection with the exercise of unit option awards 1.2 1.6 11.3 33.4 Unit option award-related cash reimbursements to EPCO 2.2 2.8 19.6 57.5 As of June 30, 2015, all compensation expense related to unit option awards had been recognized. Phantom Unit Awards Phantom unit awards allow recipients to acquire our common units (at no cost to the recipient apart from fulfilling service and other conditions) once a defined vesting period expires, subject to customary forfeiture provisions. Phantom unit awards generally vest at a rate of 25% per year beginning one year after the grant date and are non-vested until the required service periods expire. At June 30, 2015, substantially all of our phantom unit awards are expected to result in the issuance of common units upon vesting; therefore, the applicable awards are accounted for as equity-classified awards. The grant date fair value of a phantom unit award is based on the market price per unit of our common units on the date of grant. Compensation expense is recognized based on the grant date fair value, net of an allowance for estimated forfeitures, over the requisite service or vesting period. The following table presents phantom unit award activity for the period indicated: Number of Units Weighted- Average Grant Date Fair Value per Unit Phantom unit awards at December 31, 2014 3,342,390 $ 33.13 Granted (2) 3,449,240 $ 34.05 Vested (846,990 ) $ 33.08 Forfeited (133,334 ) $ 33.40 Phantom unit awards at June 30, 2015 5,811,306 $ 33.67 (1) Determined by dividing the aggregate grant date fair value of awards (before an allowance for forfeitures) by the number of awards issued. (2) The aggregate grant date fair value of phantom unit awards issued during 2015 was $117.4 million based on a grant date market price of our common units ranging from $33.72 to $34.40 per unit. An estimated annual forfeiture rate of 3.5% was applied to these awards. Our long-term incentive plans provide for the issuance of distribution equivalent rights (“DERs”) in connection with phantom unit awards. A DER entitles the participant to nonforfeitable cash payments equal to the product of the number of phantom unit awards outstanding for the participant and the cash distribution per common unit paid to our common unitholders. Cash payments made in connection with DERs are charged to partners’ equity when the phantom unit award is expected to result in the issuance of common units; otherwise, such amounts are expensed. The following table presents supplemental information regarding our phantom unit awards and DERs for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Cash payments made in connection with DERs $ 2.2 $ 1.2 $ 3.4 $ 1.2 Total intrinsic value of phantom unit awards that vested during period 2.1 1.2 28.7 1.2 For the EPCO group of companies, the unrecognized compensation cost associated with phantom unit awards was $123.3 million at June 30, 2015, of which our allocated share of the cost is currently estimated to be $113.7 million. Due to the graded vesting provisions of these awards, we expect to recognize our share of the unrecognized compensation cost for these awards over a weighted-average period of 2.1 years.

Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]
Derivative Instruments, Hedging Activities and Fair Value Measurements	In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices. In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics. Substantially all of our derivatives are used for non-trading activities. Interest Rate Hedging Activities We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements. At December 31, 2014, we did not have any interest rate hedging derivative instruments outstanding. The following table summarizes our portfolio of interest rate swaps at June 30, 2015: Hedged Transaction Number and Type of Derivatives Outstanding Notional Amount Period of Hedge Rate Swap Accounting Treatment Senior Notes OO 10 fixed-to-floating swaps $ 750.0 5/2015 to 5/2018 1.65% to 0.76% Fair value hedge Interest rate swaps exchange the stated interest rate paid on a notional amount of existing debt for the fixed or floating interest rate stipulated in the derivative instrument. Commodity Hedging Activities The prices of natural gas, NGLs, crude oil, refined products and petrochemical products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control. In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts. The following table summarizes our portfolio of commodity derivative instruments outstanding at June 30, 2015 (volume measures as noted): Volume (1) Accounting Derivative Purpose Current Long-Term Treatment Derivatives designated as hedging instruments: Natural gas processing: Forecasted natural gas purchases for plant thermal reduction (Bcf) 10.0 n/a Cash flow hedge Forecasted sales of NGLs (MMBbls) (3) 2.4 n/a Cash flow hedge Octane enhancement: Forecasted purchases of NGLs (MMBbls) 0.2 n/a Cash flow hedge Forecasted sales of octane enhancement products (MMBbls) 1.2 n/a Cash flow hedge Natural gas marketing: Forecasted purchases of natural gas for fuel (Bcf) 11.1 n/a Cash flow hedge Forecasted sales of natural gas (Bcf) 0.3 n/a Cash flow hedge Natural gas storage inventory management activities (Bcf) 9.3 n/a Fair value hedge NGL marketing: Forecasted purchases of NGLs and related hydrocarbon products (MMBbls) 27.5 n/a Cash flow hedge Forecasted sales of NGLs and related hydrocarbon products (MMBbls) 32.1 n/a Cash flow hedge Refined products marketing: Forecasted purchases of refined products (MMBbls) 4.9 n/a Cash flow hedge Forecasted sales of refined products (MMBbls) 1.5 n/a Cash flow hedge Refined products inventory management activities (MMBbls) 3.0 n/a Fair value hedge Crude oil marketing: Forecasted purchases of crude oil (MMBbls) 7.8 0.8 Cash flow hedge Forecasted sales of crude oil (MMBbls) 10.6 0.8 Cash flow hedge Derivatives not designated as hedging instruments: Natural gas risk management activities (Bcf) (4,5) 81.3 10.0 Mark-to-market NGL risk management activities (MMBbls) (5) 8.2 n/a Mark-to-market Crude oil risk management activities (MMBbls) (5) 4.9 n/a Mark-to-market (1) Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes. (2) The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2016, April 2016 and March 2018, respectively. (3) Forecasted sales of NGL volumes under natural gas processing exclude 1.3 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements. (4) Current volumes include 55.2 Bcf of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences. (5) Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets. § The objective of our anticipated future commodity purchases and sales hedging program is to hedge the margins of certain transportation, storage, blending and operational activities by locking in purchase and sale prices through the use of forward contracts and derivative instruments. § The objective of our natural gas processing hedging program is to hedge an amount of gross margin associated with these activities. We achieve this objective by executing forward fixed-price sales of a portion of our expected equity NGL production using forward contracts and commodity derivative instruments. For certain natural gas processing contracts, the hedging of expected equity NGL production also involves the purchase of natural gas for plant thermal reduction, which is hedged by executing forward fixed-price purchases using forward contracts and derivative instruments. § The objective of our inventory hedging program is to hedge the fair value of commodity products currently held in inventory by locking in the sales price of the inventory through the use of forward contracts and derivative instruments. Tabular Presentation of Fair Value Amounts, and Gains and Losses on Derivative Instruments and Related Hedged Items The following table provides a balance sheet overview of our derivative assets and liabilities at the dates indicated: Asset Derivatives Liability Derivatives June 30, 2015 December 31, 2014 June 30, 2015 December 31, 2014 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedging instruments Interest rate derivatives Other current assets $ 5.7 Other current assets $ -- Other current liabilities $ -- Other current liabilities $ -- Interest rate derivatives Other assets -- Other assets -- Other liabilities 5.5 Other liabilities -- Total interest rate derivatives 5.7 -- 5.5 -- Commodity derivatives Other current assets 117.6 Other current assets 217.9 Other current liabilities 121.0 Other current liabilities 145.3 Commodity derivatives Other assets 0.5 Other assets -- Other liabilities 0.7 Other liabilities -- Total commodity derivatives 118.1 217.9 121.7 145.3 Total derivatives designated as hedging instruments $ 123.8 $ 217.9 $ 127.2 $ 145.3 Derivatives not designated as hedging instruments Commodity derivatives Other current assets $ 13.8 Other current assets $ 8.1 Other current liabilities $ 8.2 Other current liabilities $ 0.7 Commodity derivatives Other assets 0.4 Other assets 0.6 Other liabilities 1.4 Other liabilities 1.4 Total commodity derivatives $ 14.2 $ 8.7 $ 9.6 $ 2.1 Certain of our commodity derivative instruments are subject to master netting arrangements or similar agreements.

The tabular presentation above provides a means for comparing the gross amount of derivative assets and liabilities, excluding associated accounts payable and receivable, to the net amount that would likely be receivable or payable under a default scenario based on the existence of rights of offset in the respective derivative agreements. Any cash collateral paid or received is reflected in these tables, but only to the extent that it represents variation margins. Any amounts associated with derivative prepayments or initial margins that are not influenced by the derivative asset or liability amounts or those that are determined solely on their volumetric notional amounts are excluded from these tables.

Likewise, we expect to reclassify $15.4 million of net gains attributable to commodity derivative instruments from accumulated other comprehensive income to earnings, $15.0 million as an increase in revenue and $0.4 million as a decrease in operating costs and expenses. The following table presents the effect of our derivative instruments not designated as hedging instruments on our Unaudited Condensed Statements of Consolidated Operations for the periods indicated: Derivatives Not Designated as Hedging Instruments Location Gain (Loss) Recognized in Income on Derivative For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Interest rate derivatives Interest expense $ -- $ -- $ -- $ (0.1 ) Commodity derivatives Revenue 4.2 (6.6 ) 3.9 (27.6 ) Commodity derivatives Operating costs and expenses 0.3 -- 0.3 -- Total $ 4.5 $ (6.6 ) $ 4.2 $ (27.7 ) Fair Value Measurements Our fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk, in the principal market of the asset or liability at a specified measurement date. Recognized valuation techniques employ inputs such as contractual prices, quoted market prices or rates, operating costs, discount factors and business growth rates. These inputs may be either readily observable, corroborated by market data or generally unobservable. In developing our estimates of fair value, we endeavor to utilize the best information available and apply market-based data to the highest extent possible. Accordingly, we utilize valuation techniques (such as the market approach) that maximize the use of observable inputs and minimize the use of unobservable inputs. A three-tier hierarchy has been established that classifies fair value amounts recognized in the financial statements based on the observability of inputs used to estimate such fair values. 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). At each balance sheet reporting date, we categorize our financial assets and liabilities using this hierarchy. Recurring Fair Value Measurements The following tables set forth, by level within the fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated. These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value. Our assessment of the relative significance of such inputs requires judgment. June 30, 2015 Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Financial assets: Interest rate derivatives $ -- $ 5.7 $ -- $ 5.7 Commodity derivatives 17.0 114.5 0.8 132.3 Total $ 17.0 $ 120.2 $ 0.8 $ 138.0 Financial liabilities: Liquidity Option Agreement $ -- $ -- $ 223.7 $ 223.7 Interest rate derivatives -- 5.5 -- 5.5 Commodity derivatives 21.9 107.0 2.4 131.3 Total $ 21.9 $ 112.5 $ 226.1 $ 360.5 December 31, 2014 Fair Value Measurements Using Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Financial assets: Commodity derivatives $ 37.8 $ 187.8 $ 1.0 $ 226.6 Financial liabilities: Liquidity Option Agreement $ -- $ -- $ 212.2 $ 212.2 Commodity derivatives 13.8 133.0 0.6 147.4 Total $ 13.8 $ 133.0 $ 212.8 $ 359.6 The following table sets forth a reconciliation of changes in the fair values of our recurring Level 3 financial assets and liabilities on a combined basis for the periods indicated: For the Six Months Ended June 30, Location 2015 2014 Financial asset (liability) balance, net, January 1 $ (211.8 ) $ 3.2 Total gains (losses) included in: Net income (1) Revenue (0.4 ) 4.6 Other comprehensive income Commodity derivative instruments – changes in fair value of cash flow hedges (1.5 ) -- Settlements Revenue (0.5 ) (0.1 ) Transfers out of Level 3 0.1 -- Financial asset (liability) balance, net, March 31 (214.1 ) 7.7 Total gains (losses) included in: Net income (1) Revenue (0.4 ) (3.3 ) Net income Other expense, net (11.5 ) -- Other comprehensive income Commodity derivative instruments – changes in fair value of cash flow hedges (1.0 ) -- Settlements Revenue 0.2 (1.8 ) Transfers out of Level 3 1.5 -- Financial asset (liability) balance, net, June 30 $ (225.3 ) $ 2.6 (1) There were $0.1 million and $1.1 million of unrealized losses included in these amounts for the three and six months ended June 30, 2015, respectively. There were unrealized losses of $5.0 million and $0.5 million included in these amounts for the three and six months ended June 30, 2014, respectively. The following Fair Value Financial Assets Financial Liabilities Valuation Techniques Unobservable Input Range Commodity derivatives – Crude oil $ 0.6 $ 1.1 Discounted cash flow Forward commodity prices $58.95-$61.58/barrel Commodity derivatives – Natural gasoline 0.2 1.3 Discounted cash flow Forward commodity prices $1.25-$1.27/gallon Total $ 0.8 $ 2.4 With respect to commodity derivatives, we believe forward commodity prices are the most significant unobservable inputs in determining our Level 3 recurring fair value measurements at June 30, 2015. In general, changes in the price of the underlying commodity increases or decreases the fair value of a commodity derivative depending on whether the derivative was purchased or sold. We generally expect changes in the fair value of our derivative instruments to be offset by corresponding changes in the fair value of our hedged exposures. As described in Note 15, we adjusted the expected life of OTA following exercise of the Liquidity Option Agreement to reflect an equal probability of the dissolution of OTA over each of the 30 years in our forecast period. None of the other key valuation assumptions we listed in our 2014 Form 10-K for the Liquidity Option Agreement have changed. Nonrecurring Fair Value Measurements The following table summarizes our non-cash impairment charges by segment during each of the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 NGL Pipelines & Services $ 5.2 $ 2.8 $ 6.0 $ 5.4 Crude Oil Pipelines & Services 18.1 0.8 25.9 1.8 Natural Gas Pipelines & Services 0.8 0.1 21.5 0.3 Petrochemical & Refined Products Services -- -- 0.4 5.0 Offshore Pipelines & Services 54.9 -- 58.5 -- Total $ 79.0 $ 3.7 $ 112.3 $ 12.5 These impairment charges are a component of “Operating costs and expenses” on our Unaudited Condensed Statements of Consolidated Operations. Our non-cash asset impairment charges for the six months ended June 30, 2015 primarily reflect the write-down of a long-lived asset of our Offshore Business classified as held for sale (see Note 6) and the abandonment of certain natural gas and crude oil pipeline assets in Texas. The following table summarizes our non-recurring fair value measurements for the six months ended June 30, 2015: Fair Value Measurements Using Carrying Value at June 30, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Non-Cash Impairment Loss Impairment of long-lived assets disposed of other than by sale $ -- $ -- $ -- $ -- $ 55.1 Impairment of long-lived assets to be disposed of by sale (1) 1,689.4 -- -- 1,689.4 57.2 Total $ 112.3 (1) Primarily includes long-lived assets of our Offshore Business that were reclassified to held for sale at June 30, 2015, net of an associated non-cash impairment charge of $54.8 million related to goodwill. See Note 6. Our non-cash asset impairment charges for the six months ended June 30, 2014 primarily reflect the abandonment of assets classified as property, plant and equipment. The following table summarizes our non-recurring fair value measurements for the six months ended June 30, 2014: Fair Value Measurements Using Carrying Value at June 30, 2014 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Non-Cash Impairment Loss Impairment of long-lived assets disposed of other than by sale $ -- $ -- $ -- $ -- $ 7.5 Impairment of long-lived assets to be disposed of by sale 0.1 -- -- 0.1 5.0 Total $ 12.5 Other Fair Value Information The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature. The estimated total fair value of our fixed-rate debt obligations was $23.05 billion and $22.16 billion at June 30, 2015 and December 31, 2014, respectively. The aggregate carrying value of these debt obligations was $22.33 billion and $20.48 billion at June 30, 2015 and December 31, 2014, respectively. These values are based on quoted market prices for such debt or debt of similar terms and maturities (Level 2), our credit standing and the credit standing of our counterparties. Changes in market rates of interest affect the fair value of our fixed-rate debt. The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based. We do not have any long-term investments in debt or equity securities recorded at fair value.

Assets Held for Sale [Abstract]
Assets Held for Sale [Text Block]	Offshore Gulf of Mexico Business On July 16, 2015, we announced the execution of a Purchase and Sale Agreement with Genesis whereby they agreed to acquire our Offshore Business, which primarily consists of our Offshore Pipelines & Services business segment, for approximately $1.53 billion in cash. Our Offshore Business served drilling and development regions, including deepwater production fields, in the northern Gulf of Mexico offshore Texas, Louisiana, Mississippi and Alabama. As of December 31, 2014, our Offshore Business included approximately 2,350 miles of offshore natural gas and crude oil pipelines and six offshore hub platforms. The transaction closed on July 24, 2015. We maintained ownership of this business until the closing date. We viewed our Offshore Business as an extension of our midstream energy services network. As such, the sale of these assets does not represent a strategic shift in our consolidated operations that would have a major effect on our operations and financial results. At December 31, 2014 and June 30, 2015, segment assets for our Offshore Pipelines & Services segment represented 4.3% and 4.1%, respectively, of consolidated total segment assets. Likewise, gross operating margin from this business segment represented only 3.1% and 3.4% of our consolidated total gross operating margin for the year ended December 31, 2014 and six months ended June 30, 2015, respectively. The sale of this non-strategic business allows us to redeploy capital to other business opportunities that we believe will generate a higher return for us in the future (e.g., our recent acquisition of EFS Midstream LLC (see Note 18)). Also, proceeds from the closing of this sale will reduce our need to issue additional equity to support our ongoing capital spending program. Given the status of negotiations as of June 30, 2015, this transaction met the criteria necessary to classify the underlying assets and liabilities of our Offshore Business as “held for sale.” As a result, the associated assets and liabilities of this business were reclassified to current assets and current liabilities, respectively, on our Unaudited Condensed Consolidated Balance Sheet at June 30, 2015. In addition, the noncontrolling interest attributable to this held for sale business was also identified within equity at June 30, 2015. We recorded a non-cash asset impairment charge at June 30, 2015 of approximately $54.8 million, which reflects the excess of the net assets of the business at June 30, 2015 over its estimated fair value based on the transaction price. Since the fixed and intangible assets of our Offshore Business were classified as held for sale at June 30, 2015, we no longer depreciate and amortize the subject assets. Our consolidated results of operations for the six months ended June 30, 2015 and 2014 included $44.6 million and $45.9 million, respectively, of depreciation and amortization expense attributable to these assets. Carrying Values of Major Classes of Assets and Liabilities Designated as Held for Sale The following table presents the major classes of assets and liabilities designated as held for sale on our Unaudited Condensed Consolidated Balance Sheet at June 30, 2015: Offshore Gulf of Mexico Business Assets held for sale: Current assets $ 26.9 Property, plant and equipment, net 1,135.9 Investments in unconsolidated affiliates 482.4 Intangible assets, net 37.1 Goodwill 82.0 Other assets 1.2 Subtotal 1,765.5 Impairment charge related to goodwill (54.8 ) Total presented in Current Assets $ 1,710.7 Liabilities related to assets held for sale: Current liabilities $ 24.1 Other long-term liabilities 92.3 Total presented in Current Liabilities $ 116.4 Noncontrolling interests in assets held for sale $ 62.2 Net assets of Offshore Business before impairment charge $ 1,586.9 Fair value of Offshore Business based on estimated transaction price $ 1,532.1

Property, Plant and Equipment	The historical costs of our property, plant and equipment and related accumulated depreciation balances were as follows at the dates indicated: Estimated Useful Life in Years June 30, 2015 December 31, 2014 Plants, pipelines and facilities (1) 3-45 (6) $ 31,449.8 $ 30,834.9 Underground and other storage facilities (2) 5-40 (7) 2,726.6 2,584.2 Platforms and facilities (3) 20-31 659.7 659.7 Transportation equipment (4) 3-10 159.0 154.2 Marine vessels (5) 15-30 826.1 796.4 Land 261.2 262.6 Construction in progress 3,588.2 2,754.7 Total historical cost of property, plant and equipment 39,670.6 38,046.7 Less accumulated depreciation 8,750.9 8,165.1 Subtotal property, plant and equipment, net 30,919.7 29,881.6 Carrying values reclassified to assets held for sale (8) (1,135.9 ) -- Total property, plant and equipment, net $ 29,783.8 $ 29,881.6 (1) Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; office furniture and equipment; buildings; laboratory and shop equipment and related assets. (2) Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets. (3) Platforms and facilities included offshore platforms and related facilities and other associated assets located in the Gulf of Mexico (see Note 6). (4) Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations. (5) Marine vessels include tow boats, barges and related equipment used in our marine transportation business. (6) In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; office furniture and equipment, 3-20 years; buildings, 20-40 years; and laboratory and shop equipment, 5-35 years. (7) In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years. (8) See Note 6 regarding the reclassification of $1.84 billion of offshore Gulf of Mexico property, plant and equipment values, net of $706.8 million of accumulated depreciation, to assets held for sale at June 30, 2015. The following table summarizes our depreciation expense and capitalized interest amounts for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Depreciation expense (1) $ 292.6 $ 271.0 $ 583.9 $ 538.9 Capitalized interest (2) 35.7 17.7 65.3 36.2 (1) Depreciation expense is a component of “Costs and expenses” as presented on our Unaudited Condensed Statements of Consolidated Operations. (2) We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset’s estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise. At June 30, 2015, the net carrying values of property, plant and equipment attributable to our Offshore Business were reclassified to “Assets held for sale” as discussed in Note 6. Since these assets are classified as held for sale, we will no longer depreciate the underlying historical costs after June 30, 2015. For the three and six months ended June 30, 2015, we recognized $19.7 million and $40.1 million, respectively, of depreciation expense associated with these held for sale assets. Likewise, for the three and six months ended June 30, 2014, we recognized $20.4 million and $40.8 million, respectively, of depreciation expense associated with these assets. Asset Retirement Obligations We record asset retirement obligations (“AROs”) in connection with legal requirements to perform specified retirement activities under contractual arrangements and/or governmental regulations. Our contractual AROs primarily result from right-of-way agreements associated with our pipeline operations and real estate leases associated with our plant sites. In addition, we record AROs in connection with governmental regulations associated with the abandonment or retirement of (i) above-ground brine storage pits, (ii) offshore Gulf of Mexico platform and pipeline assets and (iii) certain marine vessels. We also record AROs in connection with regulatory requirements associated with the renovation or demolition of certain assets containing hazardous substances such as asbestos. We typically fund our AROs using cash flow from operations. Property, plant and equipment at June 30, 2015 and December 31, 2014 includes $16.9 million and $31.3 million, respectively, of asset retirement costs capitalized as an increase in the associated long-lived asset. The following table presents information regarding our AROs since December 31, 2014: ARO liability balance, December 31, 2014 $ 98.3 Liabilities incurred 0.1 Liabilities settled (5.5 ) Revisions in estimated cash flows 49.0 Accretion expense 3.1 Reclassification of Offshore Business AROs to “Liabilities related to assets held for sale” (90.9 ) ARO liability balance, June 30, 2015 $ 54.1 Our AROs related to the Matagorda Gathering System, which is located in Texas state waters in the Matagorda Island area, increased $39.5 million in the second quarter of 2015 due to a change in management estimate associated with pending and future pipeline abandonment activities. In June 2015, we were notified by the U.S. Army Corps of Engineers (the “CoE”) to fully remove two pipeline segments included in this system that we had originally requested to abandon in-place. As a result, we adjusted the ARO liabilities for those pipeline segments under CoE jurisdiction to account for the estimated cost of removal. All ARO liabilities related to our Offshore Business (including those of the Matagorda Gathering System) were reclassified to “Liabilities related to assets held for sale” as presented on our Unaudited Condensed Consolidated Balance Sheet at June 30, 2015. The total amount reclassified was $90.9 million. With respect to our AROs, the following table presents our forecast of accretion expense for the periods indicated (excluding those classified as held for sale at June 30, 2015): Remainder of 2015 2016 2017 2018 2019 $ 1.8 $ 3.5 $ 3.8 $ 4.1 $ 4.4 Certain of our unconsolidated affiliates have AROs recorded at June 30, 2015 and December 31, 2014 relating to contractual agreements and regulatory requirements. These amounts are immaterial to our consolidated financial statements.

The IDRs represented contractual rights to future cash incentive distributions to be paid by Oiltanking. In February 2015 (following completion of Step 2 of the Oiltanking acquisition), the Oiltanking IDRs were cancelled and the carrying value of the IDRs were reclassified to goodwill. (2) At June 30, 2015, the carrying values of our intangible assets classified within the Offshore Pipelines & Services segment were reclassified to “Assets held for sale” as discussed in Note 6. Since these assets are classified as held for sale, we no longer amortize the underlying gross values after June 30, 2015.

During the second quarter of 2015, we retrospectively adjusted our provisional fair value estimate of the Liquidity Option Agreement by $92.8 million, with a corresponding increase to goodwill, which was allocated to the appropriate business segments at December 31, 2014 as follows: $27.5 million to NGL Pipelines & Services; $54.4 million to Crude Oil Pipelines & Services; and $10.9 million to Petrochemical & Refined Products Services. See Note 15 for additional information regarding this change. At June 30, 2015, we reclassified $82.0 million of goodwill attributable to our Offshore Pipelines & Services segment to assets held for sale (see Note 6).

Net proceeds from the issuance of these senior notes were used as follows: (i) the repayment of amounts outstanding under EPO’s commercial paper program, which included amounts we used to repay $250 million in principal amount of Senior Notes I that matured in March 2015, (ii) the repayment of amounts outstanding at the maturity of our $400 million in principal amount of Senior Notes X that matured in June 2015 and (iii) for general company purposes. Enterprise Products Partners L.P. has unconditionally guaranteed these senior notes on an unsecured and unsubordinated basis. These senior notes rank equal with EPO’s existing and future unsecured and unsubordinated indebtedness and are senior to any existing and future subordinated indebtedness of EPO. These senior notes are subject to make-whole redemption rights and were issued under an indenture containing certain covenants, which generally restrict EPO’s ability (with certain exceptions) to incur debt secured by liens and engage in sale and leaseback transactions. Letters of Credit At June 30, 2015, EPO had $2.5 million of letters of credit outstanding related to operations at our facilities and motor fuel tax obligations. Lender Financial Covenants We were in compliance with the financial covenants of our consolidated debt agreements at June 30, 2015. Information Regarding Variable Interest Rates Paid The following table presents the range of interest rates and weighted-average interest rates paid on our consolidated variable-rate debt during the six months ended June 30, 2015: Range of Interest Rates Paid Weighted-Average Interest Rate Paid Commercial Paper Notes 0.35% to 0.78% 0.61% EPO $3.5 Billion Multi-Year Revolving Credit Facility 1.15% to 3.25% 1.30%

Equity and Distributions [Abstract]
Equity and Distributions	Partners’ equity reflects the various classes of limited partner interests (i.e., common units, including restricted common units) that we have outstanding. The following table summarizes changes in the number of our outstanding units since December 31, 2014: Common Units (Unrestricted) Restricted Common Units Total Common Units Number of units outstanding at December 31, 2014 1,933,095,027 4,229,790 1,937,324,817 Common units issued in connection with at-the-market program 23,258,453 -- 23,258,453 Common units issued in connection with DRIP and EUPP 5,637,275 -- 5,637,275 Common units issued in connection with Step 2 of Oiltanking acquisition 36,827,517 -- 36,827,517 Common units issued in connection with the vesting and exercise of unit options 327,719 -- 327,719 Common units issued in connection with the vesting of phantom unit awards 556,041 -- 556,041 Common units issued in connection with the vesting of restricted common unit awards 1,940,044 (1,940,044 ) -- Forfeiture of restricted common unit awards -- (111,250 ) (111,250 ) Acquisition and cancellation of treasury units in connection with the vesting of equity-based awards (662,242 ) -- (662,242 ) Other 15,054 -- 15,054 Number of units outstanding at June 30, 2015 2,000,994,888 2,178,496 2,003,173,384 On July 1, 2015, we filed a registration statement with the SEC covering the issuance of up to $1.92 billion of our common units in amounts, at prices and on terms to be determined by market conditions and other factors at the time of such offerings. Pursuant to this “at-the-market” program, we may sell common units under an equity distribution agreement between Enterprise Products Partners L.P. and certain broker-dealers from time-to-time by means of ordinary brokers’ transactions through the NYSE at market prices, in block transactions or as otherwise agreed to with the broker-dealer parties to the agreement. The new registration statement was declared effective on August 3, 2015 and replaced our prior registration statement with respect to the at-the-market program, which was filed with the SEC in October 2013 and covered the issuance of up to $1.25 billion of our common units. Immediately prior to the effectiveness of the new registration statement, we had the capacity to issue additional common units under the at-the-market program up to an aggregate sales price of $424.6 million (after giving effect to sales of common units previously made under the program). Following the effectiveness of the new registration statement and after taking into account the aggregate sales price of common units sold under our at-the-market program through June 30, 2015 as described below, we now have the capacity to issue additional common units under our at-the-market program up to an aggregate sales price of $1.92 billion. During the six months ended June 30, 2015, we issued 23,258,453 common units under this program for aggregate gross proceeds of $767.1 million. This includes 3,225,057 common units sold in March 2015 to a privately held affiliate of EPCO, which generated gross proceeds of $100 million. After taking into account applicable costs, our transactions under the at-the-market program resulted in aggregate net cash proceeds of $760.0 million for the first six months of 2015. During the six months ended June 30, 2014, we issued 1,590,334 common units under this program for aggregate gross cash proceeds of $58.3 million, resulting in total net cash proceeds of $57.7 million. We also have registration statements on file with the SEC collectively authorizing the issuance of up to 140,000,000 of our common units in connection with a distribution reinvestment plan (“DRIP”). We issued a total of 5,453,541 common units under our DRIP during the six months ended June 30, 2015, which generated net cash proceeds of $177.8 million. During the six months ended June 30, 2014, we issued 4,890,878 common units under our DRIP, which generated net cash proceeds of $160.4 million. Privately held affiliates of EPCO reinvested $50 million through the DRIP in each of the six month periods ending June 30, 2015 and 2014 (this amount being a component of the net cash proceeds presented for both periods). After taking into account the number of common units issued under the DRIP through June 30, 2015, we have the capacity to issue an additional 22,027,808 common units under this plan. In addition to the DRIP, we have registration statements on file with the SEC authorizing the issuance of up to 8,000,000 of our common units in connection with our employee unit purchase plan (“EUPP”). We issued 183,734 common units under our EUPP during the six months ended June 30, 2015, which generated net cash proceeds of $6.3 million. During the six months ended June 30, 2014, we issued 149,060 common units under our EUPP, which generated net cash proceeds of $5.2 million. After taking into account the number of common units issued under the EUPP through June 30, 2015, we may issue an additional 6,969,334 common units under this plan. The net cash proceeds we received from the issuance of common units during the six months ended June 30, 2015 were used to temporarily reduce amounts outstanding under EPO’s commercial paper program and for general company purposes. Completion of Oiltanking Acquisition In October 2014, we completed the first step (“Step 1”) of a two-step acquisition of Oiltanking by paying approximately $4.41 billion to OTA for Oiltanking GP, the related IDRs and approximately 65.9% of the limited partner interests of Oiltanking. As a second step (“Step 2”) of the Oiltanking acquisition (separately negotiated by the conflicts committee of Oiltanking GP on behalf of Oiltanking), we entered into an Agreement and Plan of Merger (the “merger agreement”) with Oiltanking in November 2014 that provided for the following: § the merger of a wholly owned subsidiary of Enterprise with and into Oiltanking, with Oiltanking surviving the merger as a wholly owned subsidiary of Enterprise; and § all outstanding common units of Oiltanking at the effective time of the merger held by Oiltanking’s public unitholders (which consisted of Oiltanking unitholders other than Enterprise and its subsidiaries) to be cancelled and converted into Enterprise common units based on an exchange ratio of 1.30 Enterprise common units for each Oiltanking common unit. In accordance with the merger agreement and Oiltanking’s partnership agreement, the merger was submitted to a vote of Oiltanking’s common unitholders, with the required majority of unitholders (including our ownership interests) voting to approve the merger on February 13, 2015. Upon approval of the merger, a total of 36,827,517 of our common units were issued to Oiltanking’s former public unitholders. With the completion of Step 2, total consideration paid by Enterprise for Oiltanking was approximately $5.9 billion. Step 2 of the acquisition was accounted for in accordance with ASC Topic 810, Consolidations – Overall – Changes in Parent’s Ownership Interest in a Subsidiary See Note 15 for information regarding requests from the Federal Trade Commission (“FTC”) and the Attorney General of the State of Texas in connection with the Oiltanking acquisition. With the exception of the fair value assigned to the Liquidity Option Agreement (see Notes 4 and 15), we consider our purchase price allocation to be final. We expect to finalize the fair value of the Liquidity Option Agreement during the third quarter of 2015. Subsequent changes in the fair value of this option (other than those attributable to the finalization of the purchase price) will be recorded in earnings each reporting period until the option expires or is exercised. Noncontrolling Interests Noncontrolling interests represent third party equity ownership interests in our consolidated subsidiaries, including Enterprise EF78 LLC, Rio Grande Pipeline Company, Tri-States NGL Pipeline L.L.C., Panola Pipeline Company, LLC and Wilprise Pipeline Company LLC. At June 30, 2015, third party ownership in Independence Hub LLC was classified as “noncontrolling interests in assets held for sale.” Independence Hub LLC is a component of the Offshore Business that we sold to Genesis in July 2015 (see Note 6). As previously described, we reclassified approximately $1.4 billion of noncontrolling interests to limited partners’ equity in connection with completing Step 2 of the Oiltanking acquisition in February 2015. Cash distributions paid in the first quarter of 2015 to the limited partners of Oiltanking other than EPO and its subsidiaries are presented as amounts paid to noncontrolling interests. In February 2015, we formed a joint venture involving our Panola NGL Pipeline with affiliates of Anadarko Petroleum Corporation (“Anadarko”), DCP Midstream Partners, LP (“DCP”) and MarkWest Energy Partners, L.P. (“MarkWest”). We will continue to serve as operator of the Panola Pipeline and own 55% of the member interests in the joint venture. Affiliates of Anadarko, DCP and MarkWest will own the remaining 45% member interests, with each holding a 15% interest. The Panola Pipeline transports mixed NGLs from points near Carthage, Texas to Mont Belvieu, Texas and supports the Haynesville and Cotton Valley oil and gas production areas.

The Designated Units will be entitled to receive quarterly cash distributions paid, if any, beginning in the first quarter of 2016.

Business Segments [Abstract]
Business Segments	Our historical operations are reported under five business segments: (i) NGL Pipelines & Services, (ii) Crude Oil Pipelines & Services, (iii) Natural Gas Pipelines & Services, (iv) Petrochemical & Refined Products Services and (v) Offshore Pipelines & Services. Our business segments are generally organized and managed according to the types of services rendered (or technologies employed) and products produced and/or sold. As discussed in Note 6, the operations presented in our Offshore Pipelines & Services business segment were classified as held for sale as of June 30, 2015. We completed the sale of our Offshore Business on July 24, 2015. We will continue to report the historical results of the Offshore Pipelines & Services segment through the closing date of the sales transaction. Segment revenues include intersegment and intrasegment transactions, which are generally based on transactions made at market-based rates. Our consolidated revenues reflect the elimination of intercompany transactions. Substantially all of our consolidated revenues are earned in the U.S. and derived from a wide customer base. We evaluate segment performance based on the non-GAAP financial measure of gross operating margin. Gross operating margin (either in total or by individual segment) is an important performance measure of the core profitability of our operations. This measure forms the basis of our internal financial reporting and is used by our executive management in deciding how to allocate capital resources among business segments. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating segment results. The GAAP financial measure most directly comparable to total segment gross operating margin is operating income. In total, gross operating margin represents operating income exclusive of (1) depreciation, amortization and accretion expenses, (2) impairment charges, (3) gains and losses attributable to asset sales and insurance recoveries and (4) general and administrative costs. Gross operating margin includes equity in income of unconsolidated affiliates and non-refundable deferred transportation revenues relating to the make-up rights of committed shippers associated with certain pipelines. Gross operating margin by segment is calculated by subtracting segment operating costs and expenses (net of the adjustments noted above) from segment revenues, with both segment totals before the elimination of intercompany transactions. In accordance with GAAP, intercompany accounts and transactions are eliminated in consolidation. Gross operating margin is exclusive of other income and expense transactions, income taxes, the cumulative effect of changes in accounting principles and extraordinary charges. Gross operating margin is presented on a 100% basis before any allocation of earnings to noncontrolling interests. Segment assets consist of property, plant and equipment, investments in unconsolidated affiliates, intangible assets and goodwill. Segment assets exclude those amounts classified as held for sale at each balance sheet date. The carrying values of such amounts are assigned to each segment based on each asset’s or investment’s principal operations and contribution to the gross operating margin of that particular segment. Since construction-in-progress amounts (a component of property, plant and equipment) generally do not contribute to segment gross operating margin, such amounts are excluded from segment asset totals until the underlying assets are placed in service. Intangible assets and goodwill are assigned to each segment based on the classification of the assets to which they relate. Substantially all of our plants, pipelines and other fixed assets are located in the U.S. The following table presents our measurement of non-GAAP total segment gross operating margin for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Revenues $ 7,092.5 $ 12,520.8 $ 14,565.0 $ 25,430.7 Subtract operating costs and expenses (6,357.5

Fluctuations in our product sales revenues and related cost of sales amounts are explained in part by changes in energy commodity prices. In general, lower energy commodity prices result in a decrease in our revenues attributable to product sales; however, these lower commodity prices also decrease the associated cost of sales as purchase costs decline. The same correlation would be true in the case of higher energy commodity sales prices and purchase costs.

Relationship with EPCO and Affiliates We have an extensive and ongoing relationship with EPCO and its privately held affiliates (including Enterprise GP, our general partner), which are not a part of our consolidated group of companies. At June 30, 2015, EPCO and its privately held affiliates (including Dan Duncan LLC and certain Duncan family trusts, the beneficiaries of which include the estate of Dan L. Duncan) beneficially owned the following limited partner interests in us: Number of Units Percentage of Total Units Outstanding 689,490,269 34.4% We and Enterprise GP are both separate legal entities apart from each other and apart from EPCO and its other affiliates, with assets and liabilities that are also separate from those of EPCO and its other affiliates. EPCO and its privately held affiliates depend on the cash distributions they receive from us and other investments to fund their other activities and to meet their debt obligations. During the six months ended June 30, 2015 and 2014, we paid EPCO and its privately held affiliates cash distributions totaling $466.7 million and $431.8 million, respectively. In March 2015, a privately held affiliate of EPCO purchased 3,225,057 common units from us under our at-the-market program for $31.01 per unit. See Note 11 for information regarding our at-the-market program. From time-to-time, EPCO and its privately held affiliates elect to reinvest a portion of the cash distributions they receive from us into the purchase of additional common units under our DRIP. See Note 11 for information regarding reinvestments made during 2015 and 2014. We have no employees. All of our operating functions and general and administrative support services are provided by employees of EPCO pursuant to the ASA or by other service providers. The following table presents our costs and expenses attributable to the ASA and other related party transactions with EPCO for the periods indicated: For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Operating costs and expenses $ 205.8 $ 208.9 $ 396.9 $ 412.6 General and administrative expenses 30.2 30.6 61.0 62.6 Total costs and expenses $ 236.0 $ 239.5 $ 457.9 $ 475.2

Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. Phantom unit awards were first issued in February 2014. See Note 1 for information regarding a two-for-one common unit split completed in August 2014.

Commitments and Contingencies

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Litigation As part of our normal business activities, we may be named as defendants in legal proceedings, including those arising from regulatory and environmental matters. Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to fully indemnify us against losses arising from future legal proceedings. We will vigorously defend the partnership in litigation matters. Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the possible need for accounting recognition and disclosure of these contingencies. We accrue an undiscounted liability for those contingencies where the loss is probable and the amount can be reasonably estimated. If a range of probable loss amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum amount in the range is accrued. We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material to our consolidated financial statements, we disclose the nature of the contingency and, where feasible, an estimate of the possible loss or range of loss. Based on a consideration of all relevant known facts and circumstances, we do not believe that the ultimate outcome of any currently pending litigation directed against us will have a material impact on our consolidated financial statements either individually at the claim level or in the aggregate. At June 30, 2015 and December 31, 2014, our accruals for litigation contingencies were $2.7 million and $2.4 million, respectively, and were recorded in our Unaudited Condensed Consolidated Balance Sheets as a component of “Other current liabilities.” Our evaluation of litigation contingencies is based on the facts and circumstances of each case and predicting the outcome of these matters involves uncertainties. In the event the assumptions we use to evaluate these matters change in future periods or new information becomes available, we may be required to record additional accruals. In an effort to mitigate expenses associated with litigation, we may settle legal proceedings out of court. ETP Matter In connection with a proposed pipeline project, we and Energy Transfer Partners, L.P. (“ETP”) signed a non-binding letter of intent in April 2011 that disclaimed any partnership or joint venture related to such project absent executed definitive documents and board approvals of the respective companies. Definitive agreements were never executed and board approval was never obtained for the potential pipeline project. In August 2011, the proposed pipeline project was cancelled due to a lack of customer support. In September 2011, ETP filed suit against us and a third party in connection with the cancelled project alleging, among other things, that we and ETP had formed a “partnership.” The case was tried in the District Court of Dallas County, Texas, 298th Judicial District. While we firmly believe, and argued during our defense, that no agreement was ever executed forming a legal joint venture or partnership between the parties, the jury found that the actions of the two companies, nevertheless, constituted a legal partnership. As a result, the jury found that ETP was wrongfully excluded from a subsequent pipeline project involving a third party, and awarded ETP $319.4 million in actual damages on March 4, 2014. On July 29, 2014, the court entered judgment against us in an aggregate amount of $535.8 million, which includes (i) $319.4 million as the amount of actual damages awarded by the jury, (ii) an additional $150.0 million in disgorgement for the alleged benefit we received due to a breach of fiduciary duties by us against ETP and (iii) prejudgment interest in the amount of $66.4 million. The court also awarded post-judgment interest on such aggregate amount, to accrue at a rate of 5% per annum, compounded annually. We do not believe that the verdict or the judgment entered against us is supported by the evidence or the law. On March 30, 2015, we filed our Brief of the Appellant in the Court of Appeals for the Fifth District of Dallas, Texas and intend to vigorously oppose the judgment through the appeals process. As of June 30, 2015, we have not recorded a provision for this matter as management believes payment of damages in this case is not probable. FTC Matter On February 23, 2015, we received a Civil Investigative Demand and a related Subpoena Duces Tecum Contractual Obligations Scheduled Maturities of Debt With the exception of (i) routine fluctuations in the balances of our revolving credit facility and commercial paper notes outstanding, (ii) the issuance of senior notes in May 2015 and (iii) the scheduled repayment of maturing senior debt obligations, our consolidated debt obligations at June 30, 2015 did not differ materially from those reported in our 2014 Form 10-K. See Note 10 for additional information regarding our consolidated debt obligations. Operating Lease Obligations Consolidated lease and rental expense was $25.2 million and $22.5 million during the second quarters of 2015 and 2014, respectively. For the six months ended June 30, 2015 and 2014, consolidated lease and rental expense was $47.6 million and $45.7 million, respectively. Our operating lease commitments at June 30, 2015 did not differ materially from those reported in our 2014 Form 10-K. Purchase Obligations Our consolidated purchase obligations at June 30, 2015 did not differ materially from those reported in our 2014 Form 10-K. Liquidity Option Agreement As described in Note 18 of the Notes to Consolidated Financial Statements included under Part II, Item 8 of our 2014 Form 10-K, we entered into a put option agreement (the “Liquidity Option Agreement”) with OTA and Marquard & Bahls (“M&B”) in connection with the Oiltanking acquisition. Under the Liquidity Option Agreement, we granted M&B the option to sell to us 100% of the issued and outstanding capital stock of OTA at any time within a 90-day period commencing on February 1, 2020. At that time, OTA’s only significant asset is expected to be the Enterprise common units it received in Step 1 of the Oiltanking acquisition, to the extent that such common units are not sold by M&B prior to the option exercise date pursuant to a related registration rights agreement. In July 2015, we retrospectively adjusted our provisional fair value estimate for the Liquidity Option Agreement from $119.4 million to $212.2 million. The retrospective adjustment was applied in our December 31, 2014 Consolidated Balance Sheet as a $92.8 million increase in goodwill (see Note 9) and a corresponding increase in the Liquidity Option Agreement liability, which is a component of other long-term liabilities. The retrospective adjustment did not impact our historical results of operations, cash flows or other balance sheet amounts. As described in our 2014 Form 10-K, the provisional estimate represents the present value at October 1, 2014 of estimated federal and state income tax payments that we would make on the taxable income of OTA, a corporation, over a stated period of time following exercise of the option. We expect that OTA’s taxable income would, in turn, be based on an allocation of our partnership’s taxable income to the common units held by OTA and reflect any tax mitigation strategies that we believe could be employed. Our initial fair value estimate of $119.4 million was based on a variety of assumptions (each a Level 3 input), including a key assumption that a market participant would maintain the OTA corporate structure and not divest of its Enterprise common units for 30 years following exercise of the option in 2020. After further consideration, we revised this key assumption to reflect that a market participant might elect to dissolve the OTA corporate structure and sell the Enterprise common units at earlier dates. Accordingly, for purposes of our discounted cash flow model, we assigned an equal probability to the divesture of OTA and its assets over each of the 30 years in our forecast period. As a result, our provisional fair value estimate at October 1, 2014 increased by $92.8 million to $212.2 million, with a corresponding $92.8 million increase in goodwill which has been retrospectively adjusted as of December 31, 2014. This change is not considered material to our consolidated financial statements. None of the other key valuation assumptions we listed in our 2014 Form 10-K for the Liquidity Option Agreement have changed. We believe the information gathered to date provides a reasonable basis for estimating the fair value of the Liquidity Option Agreement, but we are continuing to analyze certain 2014 federal income tax return calculations that are necessary to finalize our fair value estimate. We expect to finalize the initial fair value of the Liquidity Option Agreement by the end of the third quarter of 2015. Results for the three and six months ended June 30, 2015 include $11.5 million of non-cash accretion expense associated with the change in fair value of the Liquidity Option Agreement from October 1, 2014 through June 30, 2015. The carrying value of the Liquidity Option Agreement, which is a component of “Other long-term liabilities” on our Unaudited Condensed Consolidated Balance Sheet, was $223.7 million at June 30, 2015 after recognition of this accretion amount.

Such amounts are not included under the caption “Capital expenditures” on the Unaudited Condensed Statements of Consolidated Cash Flows. On certain of our capital projects, third parties are obligated to reimburse us for all or a portion of project expenditures. The majority of such arrangements are associated with projects related to pipeline construction activities and production well tie-ins. These cash receipts are presented as “Contributions in aid of construction costs” within the investing activities section of our Unaudited Condensed Statements of Consolidated Cash Flows. In February 2011, we experienced an NGL release and fire at the West Storage location of our Mont Belvieu, Texas underground storage facility. As a final installment on the property damage claim we filed in connection with this incident, we received $95.0 million of nonrefundable cash insurance proceeds during the first quarter of 2014. Operating income for the six months ended June 30, 2014 includes $95.0 million of gains related to these proceeds. This gain was classified as a reduction in operating costs and expenses for the period.

Subsequent Event [Abstract]
Subsequent Event	Acquisition of Eagle Ford Midstream Assets In June 2015, we announced the execution of definitive agreements to purchase all of the member interests in EFS Midstream LLC (“EFS Midstream”) from affiliates of Pioneer Natural Resources Company (“Pioneer”) and Reliance Industries Limited (“Reliance”) for $2.15 billion. The purchase price will be paid in two installments, the first installment of $1.15 billion was paid at closing on July 8, 2015 and the final installment of $1.0 billion will be paid no later than the first anniversary of the closing date. The effective date of the acquisition was July 1, 2015. We funded the cash consideration for the first installment using proceeds from the issuance of short-term notes under our commercial paper program and cash on hand. EFS Midstream provides natural gas gathering, treating, compression and condensate gathering and processing services in the Eagle Ford Shale. The EFS Midstream system includes approximately 460 miles of natural gas and condensate gathering pipelines, ten central gathering plants, 780 MMcf/d of natural gas treating capacity and 119 MBPD of condensate stabilization capacity. Under the terms of the agreements, the Pioneer and Reliance joint development has dedicated its Eagle Ford Shale acreage to us under a 20-year, fixed-fee gathering agreement that includes a minimum volume requirement for the first seven years. Pioneer and Reliance have also dedicated their Eagle Ford Shale acreage under related 20-year fee-based agreements with us for natural gas processing, NGL transportation and fractionation, and for natural gas, processed condensate and crude oil transportation services. Due to the recent nature of this transaction, we have not completed the allocation of the purchase price.

General Accounting and Disclosure Matters (Policies)	6 Months Ended

General Accounting Matters [Abstract]
Contingencies	Contingencies Certain conditions may exist as of the date our consolidated financial statements are issued, which may result in a loss to us but which will only be resolved when one or more future events occur or fail to occur. Management has regular quarterly litigation reviews, including updates from legal counsel, to assess the need for accounting recognition or disclosure of these contingencies, and such assessment inherently involves an exercise in judgment. In assessing loss contingencies related to legal proceedings that are pending against us or unasserted claims that may result in such proceedings, our management and legal counsel evaluate the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought therein. We accrue an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when it is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material, we disclose the nature of the contingency and, if feasible, an estimate of the possible loss or range of loss. Loss contingencies considered remote are generally not disclosed unless they involve guarantees, in which case the guarantees would be disclosed. See Note 15 for additional information regarding our contingencies.
Derivative Instruments	Derivative Instruments We use derivative instruments such as futures, swaps, options, forward contracts and other arrangements to manage price risks associated with inventories, firm commitments, interest rates, foreign currencies and certain anticipated future commodity transactions. To qualify for hedge accounting, the hedged item must expose us to risk and the related derivative instrument must reduce the exposure to that risk and meet specific hedge documentation requirements related to designation dates, expectations for hedge effectiveness and the probability that hedged future transactions will occur as forecasted. We formally designate derivative instruments as hedges and document and assess their effectiveness at inception of the hedge and on a monthly basis thereafter. Forecasted transactions are evaluated for the probability of occurrence and are periodically back-tested once the forecasted period has passed to determine whether similarly forecasted transactions are probable of occurring in the future. For certain physical forward commodity derivative contracts, we apply the normal purchase/normal sale exception, whereby changes in the mark-to-market values of such contracts are not recognized in income. As a result, the revenues and expenses associated with such physical transactions are recognized during the period when volumes are physically delivered or received. Physical forward commodity contracts subject to this exception are evaluated for the probability of future delivery and are periodically back-tested once the forecasted period has passed to determine whether similar forward contracts are probable of physical delivery in the future. See Note 4 for additional information regarding our derivative instruments.
Estimates	Estimates Preparing our consolidated financial statements in conformity with U.S. GAAP requires us to make estimates that affect amounts presented in the financial statements. Our most significant estimates relate to (i) the useful lives and depreciation/amortization methods used for fixed and identifiable intangible assets; (ii) measurement of fair value and projections used in impairment testing of fixed and intangible assets (including goodwill); (iii) contingencies; and (iv) revenue and expense accruals. Actual results could differ materially from our estimates. On an ongoing basis, we review our estimates based on currently available information. Any changes in the facts and circumstances underlying our estimates may require us to update such estimates, which could have a material impact on our consolidated financial statements.
Restricted Cash	Restricted Cash Restricted cash represents amounts held in segregated bank accounts by our clearing brokers as margin in support of our commodity derivative instruments portfolio and related physical purchases and sales of natural gas, NGLs, crude oil and refined products. Additional cash may be restricted to maintain our commodity derivative instruments portfolio as prices fluctuate or deposit requirements change. At June 30, 2015, our restricted cash amounts were $46.1 million. We did not have any restricted cash as of December 31, 2014. See Note 4 for information regarding our derivative instruments and hedging activities.

Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]
Hedging Instruments Under the FASB's Derivative and Hedging Guidance	We may utilize interest rate swaps, forward starting swaps and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements. At December 31, 2014, we did not have any interest rate hedging derivative instruments outstanding. The following table summarizes our portfolio of interest rate swaps at June 30, 2015: Hedged Transaction Number and Type of Derivatives Outstanding Notional Amount Period of Hedge Rate Swap Accounting Treatment Senior Notes OO 10 fixed-to-floating swaps $ 750.0 5/2015 to 5/2018 1.65% to 0.76% Fair value hedge The prices of natural gas, NGLs, crude oil, refined products and petrochemical products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control. In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps, basis swaps and option contracts. The following table summarizes our portfolio of commodity derivative instruments outstanding at June 30, 2015 (volume measures as noted): Volume (1) Accounting Derivative Purpose Current Long-Term Treatment Derivatives designated as hedging instruments: Natural gas processing: Forecasted natural gas purchases for plant thermal reduction (Bcf) 10.0 n/a Cash flow hedge Forecasted sales of NGLs (MMBbls) (3) 2.4 n/a Cash flow hedge Octane enhancement: Forecasted purchases of NGLs (MMBbls) 0.2 n/a Cash flow hedge Forecasted sales of octane enhancement products (MMBbls) 1.2 n/a Cash flow hedge Natural gas marketing: Forecasted purchases of natural gas for fuel (Bcf) 11.1 n/a Cash flow hedge Forecasted sales of natural gas (Bcf) 0.3 n/a Cash flow hedge Natural gas storage inventory management activities (Bcf) 9.3 n/a Fair value hedge NGL marketing: Forecasted purchases of NGLs and related hydrocarbon products (MMBbls) 27.5 n/a Cash flow hedge Forecasted sales of NGLs and related hydrocarbon products (MMBbls) 32.1 n/a Cash flow hedge Refined products marketing: Forecasted purchases of refined products (MMBbls) 4.9 n/a Cash flow hedge Forecasted sales of refined products (MMBbls) 1.5 n/a Cash flow hedge Refined products inventory management activities (MMBbls) 3.0 n/a Fair value hedge Crude oil marketing: Forecasted purchases of crude oil (MMBbls) 7.8 0.8 Cash flow hedge Forecasted sales of crude oil (MMBbls) 10.6 0.8 Cash flow hedge Derivatives not designated as hedging instruments: Natural gas risk management activities (Bcf) (4,5) 81.3 10.0 Mark-to-market NGL risk management activities (MMBbls) (5) 8.2 n/a Mark-to-market Crude oil risk management activities (MMBbls) (5) 4.9 n/a Mark-to-market (1) Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes. (2) The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2016, April 2016 and March 2018, respectively. (3) Forecasted sales of NGL volumes under natural gas processing exclude 1.3 MMBbls of additional hedges executed under contracts that have been designated as normal sales agreements. (4) Current volumes include 55.2 Bcf of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences. (5) Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

Property, plant and equipment and accumulated depreciation [Abstract]
Estimated useful life				35 years
[1]	See Note 6 regarding the reclassification of $1.84 billion of offshore Gulf of Mexico property, plant and equipment values, net of $706.8 million of accumulated depreciation, to assets held for sale at June 30, 2015.
[2]	Depreciation expense is a component of "Costs and expenses" as presented on our Unaudited Condensed Statements of Consolidated Operations.
[3]	We capitalize interest costs incurred on funds used to construct property, plant and equipment while the asset is in its construction phase. The capitalized interest is recorded as part of the asset to which it relates and is amortized over the asset's estimated useful life as a component of depreciation expense. When capitalized interest is recorded, it reduces interest expense from what it would be otherwise.
[4]	Plants, pipelines and facilities include processing plants; NGL, natural gas, crude oil and petrochemical and refined products pipelines; terminal loading and unloading facilities; office furniture and equipment; buildings; laboratory and shop equipment and related assets.
[5]	In general, the estimated useful lives of major assets within this category are: processing plants, 20-35 years; pipelines and related equipment, 5-45 years; terminal facilities, 10-35 years; office furniture and equipment, 3-20 years; buildings, 20-40 years; and laboratory and shop equipment, 5-35 years.
[6]	Underground and other storage facilities include underground product storage caverns; above ground storage tanks; water wells and related assets.
[7]	In general, the estimated useful lives of assets within this category are: underground storage facilities, 5-35 years; storage tanks, 10-40 years; and water wells, 5-35 years.
[8]	Platforms and facilities include offshore platforms and related facilities and other associated assets located in the Gulf of Mexico.
[9]	Transportation equipment includes tractor-trailer tank trucks and other vehicles and similar assets used in our operations.
[10]	Marine vessels include tow boats, barges and related equipment used in our marine transportation business.

[1]	At June 30, 2015, the carrying values of our intangible assets classified within the Offshore Pipelines & Services segment were reclassified to "Assets held for sale" as discussed in Note 6. Since these assets are classified as held for sale, we no longer amortize the underlying gross values after June 30, 2015.
[2]	At December 31, 2014, we had indefinite-lived intangible assets outstanding with a carrying value of $1.46 billion recorded in connection with our acquisition of the Oiltanking IDRs in October 2014. The IDRs represented contractual rights to future cash incentive distributions to be paid by Oiltanking. In February 2015 (following completion of Step 2 of the Oiltanking acquisition), the Oiltanking IDRs were cancelled and the carrying value of the IDRs were reclassified to goodwill.

Cash payments made in connection with DERs are nonforfeitable. As a result, the phantom units are considered participating securities for purposes of computing basic earnings per unit. Phantom unit awards were first issued in February 2014.
