Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Operations	Note 1. Organization and Nature of Operations Organization We are a growth-oriented Delaware master limited partnership formed in December 2014 by Noble Energy, Inc. (Noble, NBL or Parent) to own, operate, develop and acquire a wide range of domestic midstream infrastructure assets. Our current areas of focus are in the DJ Basin in Colorado and the Delaware Basin in Texas, where additional midstream assets are currently under construction. On September 20, 2016, we completed our initial public offering (the Offering) of 14,375,000 common units representing limited partner interests in the Partnership (common units), which included 1,875,000 common units issued pursuant to the underwriters’ exercise of their option to purchase additional common units, at a price to the public of $22.50 per common unit ( $21.20625 per common unit, net of underwriting discounts). The Offering was pursuant to our Registration Statement on Form S-1, as amended, filed with the Securities and Exchange Commission and declared effective on September 14, 2016. Our common units are traded on the New York Stock Exchange under the symbol “NBLX.” We received gross proceeds of $323.4 million from the Offering. Net proceeds totaled $299 million , after deducting underwriting discounts, structuring fees and offering expenses of $24.4 million . We distributed $296.8 million to Noble and paid $1.9 million of origination fees and expenses relating to our revolving credit facility. See Note 5. Debt . Contributed Businesses In connection with the Offering, Noble contributed to us ownership interests in the DevCos. The contributed DevCos include the following: DevCo Areas Served NBLX Dedicated Service Current Status of Asset NBLX Ownership Noncontrolling Interest (1) Colorado River DevCo LP Wells Ranch IDP (DJ Basin) East Pony (DJ Basin) All Noble DJ Basin Acreage Crude Oil Gathering Natural Gas Gathering Water Services Crude Oil Gathering Crude Oil Treating Operational Operational Operational 80% 20% San Juan River DevCo LP East Pony IDP (DJ Basin) Water Services Operational 25% 75% Green River DevCo LP Mustang IDP (DJ Basin) Crude Oil Gathering Natural Gas Gathering Water Services Planning Planning Partially Operational 25% 75% Laramie River DevCo LP Greeley Crescent IDP (DJ Basin) Crude Oil Gathering Water Services Under Construction 100% N/A Blanco River DevCo LP Delaware Basin Crude Oil Gathering Produced Water Services Under Construction 25% 75% Gunnison River DevCo LP Bronco IDP (DJ Basin) Crude Oil Gathering Water Services Future Development 5% 95% (1) The noncontrolling interest represents Noble's retained ownership interest in each DevCo. Noble also contributed to us other assets, consisting primarily of a 3.33% ownership interest in White Cliffs Pipeline L.L.C. (the White Cliffs Interest). The White Cliffs Pipeline system consists of two 527 -mile crude oil pipelines that extend from the DJ Basin to Cushing, Oklahoma. In exchange for the Contributed Businesses, Noble received: • a total of 1,527,584 common units, representing a 4.8% limited partner interest in the Partnership; • a total of 15,902,584 subordinated units, representing an approximate 50.0% limited partner interest in the Partnership; • Incentive Distribution Rights (IDRs) in the Partnership; • an initial cash distribution of $296.8 million from the Partnership; and • a non-economic general partnership interest in the Partnership, through the general partner, Noble Midstream GP LLC, which is not entitled to receive cash distributions. Nature of Operations Through our ownership interests in the DevCos, we operate and own interests in the following assets, some of which are currently under construction: • crude oil and natural gas gathering systems; • crude oil treating facilities; • produced water collection, gathering, and cleaning systems; and • fresh water storage and delivery systems. We generate revenues primarily by charging fees on a per unit basis for gathering crude oil and natural gas, delivering and storing fresh water, and collecting, cleaning and disposing of produced water. We have entered into multiple fee-based commercial agreements with Noble, each with an initial term of 15 years, to provide these services which are critical to Noble’s upstream operations. Our agreements include substantial acreage dedications. See Note 3. Transactions with Affiliates . Predecessor References in this report to “Predecessor,” “we,” “our,” “us” or like terms, when referring to periods prior to September 20, 2016, refer to Noble's Contributed Businesses, our Predecessor for accounting purposes. References to “the Partnership,” “we,” “our," “us” or like terms, when referring to periods after September 20, 2016, refer to the partnership.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Basis of Presentation	Note 2. Summary of Significant Accounting Policies and Basis of Presentation Presentation The accompanying consolidated financial statements for periods prior to September 20, 2016 represent the Contributed Businesses as the accounting Predecessor to the Partnership, presented on a carve-out basis of Noble’s historical ownership of the Predecessor. The Predecessor financial statements have been prepared from the separate records maintained by Noble and may not necessarily be indicative of the actual results of operations that might have occurred if the Predecessor had been operated separately during the periods reported. Because a direct ownership relationship did not exist among the businesses comprising the Predecessor, the net investment in the Predecessor is shown as Parent Net Investment, in lieu of partners' equity, in the accompanying Consolidated Balance Sheet and Consolidated Statements of Changes in Equity for years prior to December 31, 2016. Certain prior-period amounts have been reclassified to conform to the current-period presentation. The Partnership has no items of other comprehensive income or loss; therefore, its net income is identical to its comprehensive income. Consolidation Our consolidated financial statements include our accounts and the accounts of the DevCos, each of which we control as general partner. All intercompany balances and transactions have been eliminated upon consolidation. In addition, we use the cost method for our White Cliffs Interest as we have virtually no influence over its operations and financial policies. Under the cost method of accounting, we recognize cash distributions from White Cliffs Pipeline L.L.C. as investment income in our consolidated statement of operations to the extent there is net income, and record cash distributions in excess of our ratable share of earnings as return of investment, and record them as investment income in the accompanying consolidated statements of operations. Segment Information Accounting policies for reportable segments are the same as those described in this footnote. Transfers between segments are accounted for at market value. We do not consider interest income and expense or income tax benefit or expense in our evaluation of the performance of reportable segments. See Note 7. Segments . Consolidated Variable Interest Entities We have determined that the partners with equity at risk in each of the DevCos lack the authority, through voting rights or similar rights, to direct the activities that most significantly impact their economic performance; therefore, each DevCo is considered a variable interest entity, or VIE. Through our 100% ownership interest in Noble Midstream Services, LLC, a Delaware limited liability company which owns controlling interests in each of the DevCos, we have the authority to direct the activities that most significantly affect economic performance and the obligation to absorb losses or the right to receive benefits that could be potentially significant to us. Therefore, we are considered the primary beneficiary and consolidate each of the DevCos. All financial statement activity associated with our DevCos is captured within the Gathering Systems and Fresh Water Delivery reportable segments. See Note 7. Segments . Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic and commodity price environment. Revenue Recognition We generate revenues primarily by charging fees on a per unit basis for gathering crude oil and natural gas, delivering and storing fresh water, and collecting, cleaning and disposing of produced water. We recognize revenue when services have been rendered, the prices are fixed or determinable, and collectibility is reasonable assured. Property, Plant and Equipment Property and equipment primarily consists of crude oil and natural gas gathering systems, produced water collection, gathering, and cleaning systems, fresh water storage and delivery systems and crude oil treating facilities. Property and equipment is stated at the lower of of historical cost less accumulated depreciation, or fair value, if impaired. We capitalize construction-related direct labor and incremental costs, such as interest expense. Capitalized interest totaled $0.8 million in 2016 , $2.5 million in 2015 , and $1.6 million in 2014 . Maintenance and repair costs are expensed as incurred. Prior to January 1, 2015, certain assets were accounted for under the successful efforts method of accounting within Noble’s accounting policies. In January 2015, Noble changed our method of depreciation from units-of-production to the straight-line method for future accounting periods. This change is a change in accounting estimate that is effected by a change in accounting principle. When the two are inseparable, the change is accounted for as a change in accounting estimate. For assets that were converted from the unit-of-production method, their respective asset lives are 30 years from the date originally placed into service. Depreciation is computed over the asset’s estimated useful life using the straight line method based on estimated useful lives and asset salvage values. Determination of depreciation expense requires judgment regarding the estimated useful lives and salvage values of property, plant and equipment. As circumstances warrant, depreciation estimates are reviewed to determine if any changes in the underlying assumptions are necessary. The weighted average life of our long-lived assets is 30 years. The depreciation of fixed assets recorded under capital lease agreements is included in depreciation and amortization expense. See Note 4. Property, Plant and Equipment . Impairment of Long-Lived Assets We routinely assess whether impairment indicators arise during any given quarter and have processes in place to ensure that we become aware of such indicators. Impairment indicators include, but are not limited to, sustained decreases in commodity prices, a decline in customer well results and lower throughput forecasts, and increases in construction or operating costs. In the event that impairment indicators exist, we conduct an impairment test. We evaluate our ability to recover the carrying amounts of long-lived assets and determine whether such long-lived assets have been impaired. Impairment exists when the carrying value of an asset exceeds the estimated undiscounted future cash flows expected to result from the use and eventual disposition of the asset. When the carrying amount of a long-lived asset exceeds its estimated undiscounted future cash flows, the carrying amount of the asset is reduced to its estimated fair value. Fair value may be estimated using comparable market data, a discounted cash flow method, or a combination of the two. No impairments have been recorded through December 31, 2016. Asset Retirement Obligations Asset retirement obligations (ARO) consist of estimated costs of dismantlement, removal, site reclamation and similar activities associated with our property and equipment. We recognize the fair value of a liability for an ARO in the period in which it is incurred when we have an existing legal obligation associated with the retirement of our infrastructure assets and the obligation can reasonably be estimated. The associated asset retirement cost is capitalized as part of the carrying cost of the infrastructure asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as: the existence of a legal obligation for an ARO; estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. In periods subsequent to initial measurement of the ARO, we recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Revisions also result in increases or decreases in the carrying cost of the asset. Increases in the ARO liability due to passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through depreciation and amortization. See Note 6. Asset Retirement Obligations . Fair Value Measurements We measure assets and liabilities requiring fair value presentation and disclose such amounts according to the quality of valuation inputs under the fair value hierarchy. The carrying amounts of our cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature and maturity of the instruments and use Level 1 inputs. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include unrestricted cash on hand and investments with original maturities of three months or less at the time of purchase. Transactions with Affiliates Transactions between Noble, its affiliates and us have been identified in the consolidated financial statements as transactions with affiliates. See Note 3. Transactions with Affiliates . Debt Origination Fees and Expenses Debt origination fees and expenses of $1.9 million associated with our Revolving Credit Facility are included in deferred charges and amortized on a straight line basis over the five -year term. Amortization is included in interest expense. See Note 5. Debt . Capital Lease Obligation We entered into a capital lease for a pond to be used in our fresh water delivery system. The amount of the capital lease obligation is based on the discounted present value of future minimum lease payments, and therefore does not reflect future cash lease payments. The amount due within one year equals the amount by which the capital lease obligation is expected to be reduced during the next 12 months. The lease has a discounted present value of future minimum lease payments of $4.8 million as of December 31, 2016 . See Note 8. Commitments and Contingencies . Unit-Based Compensation Unit-based compensation issued to directors is recorded at grant-date fair value. Expense is recognized on a straight-line basis over the requisite service period (generally the vesting period of the award) in the consolidated statements of operations. See Note 9. Unit-Based Compensation . Supplemental Cash Flow Information We accrued $3.9 million and $13.3 million related to midstream capital expenditures as of December 31, 2016 and 2015 , respectively. Immediately prior to closing of the Offering, the Partnership recorded an adjustment to equity of $41.4 million for the elimination of current and deferred tax liabilities, representing a significant non-cash activity. Concentration of Credit Risk For all periods presented, 100% of our revenues are from Noble and its affiliates. Income Taxes For the period subsequent to the Offering, our consolidated financial statements do not include a provision for income taxes as the Partnership is generally not subject to federal or state income tax. Each partner is separately taxed on its share of taxable income. For periods prior to the Offering, our consolidated financial statements include a provision for tax expense on income related to the assets that Noble contributed to the Partnership at the Offering date. Deferred federal and state income taxes were provided on temporary differences between the financial statement carrying amounts of recognized assets and liabilities and their respective tax bases as if the partnership filed tax returns as a stand-alone entity. Litigation and Other Contingencies We may become subject to legal proceedings, claims and liabilities that will arise in the ordinary course of business. We will accrue for losses associated with legal claims when such losses are considered probable and the amounts can be reasonably estimated. See Note 8. Commitments and Contingencies . Recently Issued Accounting Standards In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-18: Statement of Cash Flows - Restricted Cash (ASU 2016-18). ASU 2016-18 requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. This ASU will be effective for annual and interim periods beginning after December 15, 2017, with earlier application permitted. We do not believe adoption of ASU 2016-18 will have a material impact on our statement of cash flows and related disclosures. In October 2016, the FASB issued Accounting Standards Update No. 2016-17: Consolidation - Interests Held through Related Parties That Are under Common Control (ASU 2016-17) . The update changes the process through which a reporting entity determines whether it is the primary beneficiary of a VIE. As a result, the single decision maker of a VIE uses economic exposure to determine its classification as the primary beneficiary as opposed to evaluating which party is most closely associated with the VIE. In February 2015, the FASB issued ASU 2015-02, which changed the guidance as to whether an entity is a VIE or a voting interest entity and how related parties are considered in the VIE model. Under the provisions of both Accounting Standards Updates, each DevCo is considered a VIE, and we are considered the primary beneficiary of that VIE. We have adopted these provisions, which did not have a material effect on our financial statements. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15) . ASU 2016-15 clarifies the presentation of certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 will be effective for annual and interim periods beginning after December 15, 2017, with earlier application permitted. We do not believe adoption of ASU 2016-15 will have a material impact on our statement of cash flows and related disclosures as this update pertains to classification of items and is not a change in accounting principle. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (ASU 2016-02). ASU 2016-02 requires a lessee to record a right of use asset and a corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. ASU 2016-02 is effective for all interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. In the normal course of business, we enter into capital and operating lease agreements to support our operations and may lease water-related, field-related and other assets. We are in the process of evaluating the impact of ASU 2016-02 on our financial statements and disclosures. We believe the adoption and implementation of ASU 2016-02 may have a material impact on our balance sheet resulting from an increase in both assets and liabilities relating to leasing activities. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), which creates Topic 606, Revenue from Contracts with Customers . In summary, the core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, ASU 2014-09 requires enhanced financial statement disclosures over revenue recognition as part of the new accounting guidance. The standard will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. In March 2016, the FASB released certain implementation guidance through ASU 2016-08 to clarify principal versus agent considerations. We are continuing to evaluate the provisions of ASU 2014-09 and have not yet determined the full impact it may have on our financial position and results of operations.

Related Party Transactions [Abstract]
Transactions with Affiliates	Note 3. Transactions with Affiliates Revenues We derive substantially all of our revenues from commercial agreements with Noble. See Agreements with Noble, below. Revenues generated from commercial agreements with Noble and its affiliates included the following: Year Ended December 31, (in thousands) 2016 2015 2014 Midstream Services — Affiliate Crude Oil, Natural Gas and Produced Water Gathering $ 94,160 $ 56,042 $ — Fresh Water Delivery 60,001 27,097 — Crude Oil Treating 5,371 4,403 2,086 Other 1,192 295 — Total Midstream Services — Affiliate $ 160,724 $ 87,837 $ 2,086 Expenses Historically, we have been operated as part of the consolidated operations of Noble, and a substantial number of our transactions are with Noble and its affiliates. Noble provides substantial labor and overhead support for us. In January 2015, Noble began charging us a fixed fee for overhead and support services. Prior to this agreement, our Predecessor’s general and administrative expense included an allocation of charges for the management and operation of our assets by Noble for general and administrative services, such as information technology, treasury, accounting, human resources and legal services and other financial and administrative services. Following the completion of the Offering, Noble charges us a combination of direct and allocated charges for general and administrative services. See Agreements with Noble, below. General and administrative expense included the following: Year Ended December 31, (in thousands) 2016 2015 2014 General and Administrative Expense — Affiliate $ 6,984 $ 2,285 $ 6,734 General and Administrative Expense — Third Party 2,930 486 — Total General and Administrative Expense $ 9,914 $ 2,771 $ 6,734 Asset Sale and Purchases — Affiliate During third quarter 2016, we sold certain equipment to Noble, at cost, and received proceeds of $1.9 million . No gain or loss was recognized for the transaction. During fourth quarter 2016, we purchased certain equipment from Noble, at market value, for approximately $0.9 million . Agreements with Noble We have entered into various agreements with Noble, as summarized below: Commercial Agreements Our commercial agreements with Noble provide for fees based on the type and scope of the midstream services we provide and the midstream system we use to provide our services, as follows: • Crude Oil Gathering Agreement - Under the applicable crude oil gathering agreement, we receive a volumetric fee per barrel (Bbl) for the crude oil gathering services we provide. • Natural Gas Gathering Agreement - Under the natural gas gathering agreement, we receive a volumetric fee per million British Thermal Units (MMBtu) for the natural gas gathering services we provide. • Produced Water Services Agreement - Under the applicable produced water services agreement, we receive a fee for collecting, cleaning or otherwise disposing of water produced from operating crude oil and natural gas wells in the dedication area. The fee is comprised of a volumetric component for services we provide directly and a pass through component for services we provide through contracts with third parties. • Fresh Water Services Agreement - Under the applicable fresh water services agreement, we receive a fee for delivering fresh water. The fee is comprised of a volumetric component for services we provide directly and a pass through component for services we provide through contracts with third parties. The cost of storing the fresh water is included in the delivery fee. • Crude Oil Treating Agreement - Under the crude oil treating agreement, we receive a monthly fee for the crude oil treating services we provide based on each well operated by Noble that is producing in paying quantities that is not connected to our crude oil gathering systems during such month. Under each of these commercial agreements, the volumetric fees we charge Noble (other than pass through fees) are automatically increased each calendar year by 2.5% . In addition, we will propose a redetermination of the fees charged under our various systems on an annual basis, taking into account, among other things, expected capital expenditures necessary to provide our services under the applicable development plan. However, if we and Noble are unable to agree on a fee redetermination (other than the automatic annual adjustment), the prior fee will remain in effect, which in effect allows Noble to unilaterally exercise control over the decision of whether to change the fee. Omnibus Agreement Our omnibus agreement with Noble provides for: • our payment of an annual general and administrative fee, initially in the amount of $6.9 million (prorated for the first year of service), for the provision of certain services by Noble and its affiliates, which fee cannot be increased until after the third anniversary of the Offering with annual redetermination thereafter; • our right of first refusal on existing Noble and future Noble acquired assets and the right to provide certain services, including the right to provide crude oil gathering, natural gas gathering and processing, and water services on certain acreage owned, or to be acquired, by Noble; • our right of first offer to acquire Noble’s retained interests in each of the development companies; and • an indemnity by Noble for certain environmental and other liabilities, and our obligation to indemnify Noble for events and conditions associated with the operations of its assets that occur after the closing of the Offering and for environmental liabilities related to our assets to the extent Noble is not required to indemnify us. Operational Services Agreement Our Operational Services and Secondment Agreement (Operational Services Agreement) with Noble provides for: • secondment by Noble of certain operational, construction, design and management employees and contractors to our general partner, us and our subsidiaries to provide management, maintenance and operational functions with respect to our assets. These functions include performing the activities and day-to-day management of the business pursuant to certain commercial agreements listed in the Operational Services Agreement, and designing, building, constructing and otherwise installing the infrastructure required by such agreements; • reimbursement by us to Noble of the cost of the seconded employees and contractors, including their wages and benefits, based on the percentage of the employee’s or contractor’s time spent working for us; and • an initial term of 15 years and automatic extensions for successive renewal terms of one year each, unless terminated by either party.

Debt Disclosure [Abstract]
Debt	Note 5. Debt Revolving Credit Facility On September 20, 2016 , we entered into a $350 million revolving credit facility with Noble Midstream Services, LLC (NMS), our wholly-owned subsidiary, as borrower. The revolving credit facility has a five -year maturity and includes a letter of credit sublimit of up to $100 million for issuances of letters of credit. The borrowing capacity on the revolving credit facility, which may be increased by an additional $350 million subject to certain conditions, is available to fund working capital and to finance drop down acquisitions and other capital expenditures. We incurred $1.9 million of origination fees and expenses, of which approximately $1.8 million remains unamortized as of December 31, 2016 . There were no amounts outstanding under the revolving credit facility as of December 31, 2016 . All obligations of NMS, as the borrower, are guaranteed by the Partnership and all wholly-owned material subsidiaries of the Partnership. The guarantees may be released in the future upon the occurrence of certain events, including the Partnership or NMS receiving an investment grade debt rating or the Partnership maintaining a rolling four-quarter consolidated EBITDA, as defined in the credit agreement, in excess of $250 million . Borrowings under the revolving credit facility bear interest at a rate equal to an applicable margin plus, at our option, either: • in the case of base rate borrowings, a rate equal to the highest of (1) the prime rate, (2) the greater of the federal funds rate or the overnight bank funding rate, plus 0.5% and (3) the LIBOR for an interest period of one month plus 1.00% ; or • in the case of LIBOR borrowings, the offered rate per annum for deposits of dollars for the applicable interest period. The unused portion of the revolving credit facility is subject to a commitment fee. Commitment fees began to accrue beginning on the date we entered into the revolving credit facility. Until such time as we or NMS obtain a credit rating from either Moody’s or Standard & Poor’s Financial Services, the commitment fee and the interest-rate margins will be based on a leverage based pricing grid, the consolidated leverage ratio being consolidated funded debt to consolidated EBITDA (as described in the credit agreement) for the prior four fiscal quarters. After we obtain a credit rating, the pricing levels will be based on a ratings based pricing grid (as described in the credit agreement). As of December 31, 2016 , the commitment fee rate was 0.2% . The credit agreement contains customary affirmative and negative covenants and events of default relating to NMS, the Partnership and their respective subsidiaries, including, among other things, limitations on the incurrence of indebtedness and liens, the making of investments, the sale of assets, transactions with affiliates, merging or consolidating with another company and the making of restricted payments. The credit agreement also contains specific provisions limiting us from engaging in certain business activities and events of default relating to certain changes in control, including Noble ceasing to own and control 51% of the voting interests of the general partner. Dividends and distributions are permitted so long as: • no event of default exists on the date of the declaration of such dividend or distribution or would result from such declaration; • we are in pro-forma compliance with the consolidated leverage ratio (as described below) under the revolving credit facility on the date of such declaration; and • such dividend or distribution is made within 60 days of such declaration. In addition, the credit agreement requires us to comply with the following financial covenants as of the end of each fiscal quarter: • a consolidated leverage ratio prior to the date that consolidated EBITDA for four fiscal quarters is less than $135 million , of less than or equal to 4 to 1 (except following certain acquisitions the consolidated leverage ratio shall be less than or equal to 4.5 to 1); • a consolidated leverage ratio on or after the date that consolidated EBITDA for four fiscal quarters exceeds $135 million , of less than or equal to 5 to 1 (except following certain acquisitions the consolidated leverage ratio shall be less than or equal to 5.5 to 1); and • a consolidated interest coverage ratio of not less than 3 to 1. Certain lenders that are a party to the credit agreement have in the past performed, and may in the future from time to time perform, investment banking, financial advisory, lending or commercial banking services for us for which they have received, and may in the future receive, customary compensation and reimbursement of expenses.

(2) For the period subsequent to the Offering, our consolidated financial statements do not include a provision for income taxes, as we are treated as a partnership for federal and state income tax purposes. Each partner is separately taxed on its share of taxable income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 8. Commitments and Contingencies Legal Proceedings We may become involved in various legal proceedings in the ordinary course of business. These proceedings would be subject to the uncertainties inherent in any litigation, and we will regularly assess the need for accounting recognition or disclosure of these contingencies. We will defend ourselves vigorously in all such matters. For periods prior to the Offering, we were part of Noble’s integrated business. In the ordinary course of business, Noble is from time to time party to various judicial and administrative proceedings. As of December 31, 2016 and December 31, 2015 , Noble did not have accrued liabilities for any legal contingencies related to us. Based on currently available information, we believe it is unlikely that the outcome of known matters would have a material adverse impact on our combined financial condition, results of operations or cash flows. Omnibus Agreement Our omnibus agreement with Noble contractually requires us to pay a fixed annual fee of $6.9 million (prorated for the first year of service) to Noble for certain administrative and operational support services being provided to us. The omnibus agreement generally remains in full force and effect so long as Noble controls our general partner. See Note 3. Transactions with Affiliates . Capital Lease During third quarter 2016, we leased a pond for use in our fresh water delivery system. We are accounting for the lease as a capital lease. The discounted present value of future minimum lease payments totals $4.8 million . Minimum commitments as of December 31, 2016 are as follows: (in thousands) Surface Lease Obligations Purchase Obligations (1) Future Minimum Capital Lease Payments Omnibus Fee (2) 2017 $ 58 $ 19,287 $ 4,851 $ 6,850 2018 58 — — 6,850 2019 58 — — 6,850 2020 58 — — — 2021 59 — — — 2022 and Beyond 150 — — — Total $ 441 $ 19,287 $ 4,851 $ 20,550 (1) Purchase obligations represent contractual agreements to purchase goods or services that are enforceable, are legally binding and specify all significant terms, including fixed and minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. The amount represents the short-term obligation to purchase pipe for use in our capital projects.

Unit-Based Compensation	Note 9. Unit-Based Compensation In connection with the Offering, the Board of Directors of our general partner adopted the Noble Midstream Partners LP 2016 Long-Term Incentive Plan (the LTIP). The LTIP provides for the grant, from time to time at the discretion of the Board of Directors, of unit awards, restricted units, phantom units (the nomenclature used in accounting literature), unit options, unit appreciation rights, distribution equivalent rights, profits interest units and other unit-based awards. The purpose of awards under the LTIP is to provide additional incentive compensation to individuals providing services to us, and to align the economic interests of such individuals with the interests of our unitholders. The LTIP limits the number of units that may be delivered pursuant to vested awards to 1,860,000 common units, subject to proportionate adjustment in the event of unit splits and similar events. Common units subject to awards that are canceled, forfeited, withheld to satisfy exercise prices or tax withholding obligations or otherwise terminated without delivery of common units will be available for delivery pursuant to other awards. Effective October 28, 2016, we awarded 3,934 restricted common units with a fair value of $120 thousand to each of our two outside directors. The restricted units will vest one year from the effective date. As of December 31, 2016 , $198 thousand of compensation cost related to all of our unvested restricted common units awarded under the LTIP remained to be recognized. The cost is expected to be recognized over a period of 0.8 years. Cash distributions on the restricted common units will accumulate and be paid upon vesting.

Earnings Per Share [Abstract]
Net Income Per Limited Partner Unit	Note 10. Net Income Per Limited Partner Unit Net income per unit applicable to common and subordinated unitholders is computed by dividing the respective limited partners’ interest in net income for the period subsequent to the Offering by the weighted-average number of common units and subordinated units outstanding for the period. The common and subordinated unitholders represent an aggregate 100% limited partner interest in us. Because we have more than one class of participating securities, we use the two-class method when calculating the net income per unit applicable to limited partners. The classes of participating securities include common units and subordinated units. Pursuant to our partnership agreement, to the extent that the quarterly distributions exceed certain target levels, Noble is entitled to receive certain incentive distributions that will result in more net income proportionately being allocated to Noble than to the holders of common units and subordinated units. Our calculation of net income per common and subordinated units is as follows: (in thousands except per unit amounts) Common Units — Public Common Units — Noble Subordinated Units — Noble Total Period Subsequent to the Offering on September 20, 2016 to December 31, 2016 Distribution Declared (1) $ 6,229 $ 662 $ 6,891 $ 13,782 Income in Excess of Distribution Declared 6,633 705 7,338 14,676 Net Income Attributable to Noble Midstream Partners LP Subsequent to the Offering on September 20, 2016 $ 12,862 $ 1,367 $ 14,229 $ 28,458 Weighted Average Units Outstanding: Basic and Diluted 14,375 1,528 15,903 31,806 Net Income Subsequent to the Offering on September 20, 2016 Per Limited Partner Unit: Basic and Diluted $ 0.89 $ 0.89 $ 0.89 $ 0.89 (1) No distribution was declared for the 10-day period ended September 30, 2016. The distribution for the quarter ending December 31, 2016 was adjusted by an amount that covers the period beginning on the closing of the Offering on September 20, 2016 and ending on September 30, 2016, based on the number of days in that period. On January 26, 2017 , the Board of Directors declared a quarterly cash distribution of $0.4333 per common unit. The distribution will be paid February 14, 2017 , to unitholders of record on February 6, 2017 . The distribution is comprised of $0.3925 per unit for the fourth quarter 2016 and $0.0408 per unit for the 10-day period following the closing of the Offering through September 30, 2016.

Income Taxes	Note 11. Income Taxes We are not a taxable entity for U.S. federal income tax purposes or for the majority of states that impose an income tax. Taxes are generally borne by our partners through the allocation of taxable income and, accordingly for the periods subsequent to the offering date we do not record deferred taxes related to the aggregate difference in the basis of our assets for financial and tax reporting purposes. Our income tax provision (benefit) consists of the following: Year Ended December 31, (in thousands) 2016 2015 2014 Current $ 15,450 $ 164 $ 4 Deferred 12,838 23,062 (9,182 ) Total Income Tax Provision (Benefit) $ 28,288 $ 23,226 $ (9,178 ) Effective Tax Rate 24.9 % 37.9 % 37.8 % The increase in income tax expense for the year ended December 31, 2016 as compared with the years ended December 31, 2015 and December 31, 2014 was primarily due to an increase in income before income taxes earned prior to the Offering date, which is subject to federal and state income tax. The increase in income tax expense was partially offset by the impact of the Partnership's non-taxable status for the period beginning on the Offering date and ending on December 31, 2016. Our effective tax rate for the year ended December 31, 2016 varied as compared with the years ended December 31, 2015 and December 31, 2014 primarily due to the Partnership's U.S. federal income tax status as a non-taxable entity for the period subsequent to the Offering date. The effective tax rate for the period beginning on January 1, 2016 and ending on the Offering date was 38.1% . See Note 2. Summary of Significant Accounting Policies and Basis of Presentation above for discussion of elimination of current and deferred tax liabilities prior to the Offering.

Subsequent Events	Note 12. Subsequent Events On February 12, 2017, through our indirectly wholly-owned subsidiary Trinity River DevCo LLC (Trinity), we entered into a Subscription Agreement with Plains Pipeline, L.P. (Plains), a wholly-owned subsidiary of Plains All American Pipeline L.P., pursuant to which we and Plains will enter into a 50 /50 joint venture (the Advantage Joint Venture) to acquire Advantage Pipeline, L.L.C. (Advantage), which owns a 16 -inch crude oil pipeline system extending approximately 70 miles from Pecos, Texas to Crane County, Texas (the Advantage Pipeline System). Through Trinity, we will acquire a 50% interest in the Advantage Joint Venture for $66.5 million to be funded with cash and our revolving credit facility, which we amended on February 12, 2017 to permit Trinity’s investment in the Advantage Joint Venture. Once formed, the Advantage Joint Venture will acquire Advantage for approximately $133 million . The closing of the joint venture is conditioned upon the termination or expiration of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the execution on satisfactory terms of certain ancillary agreements to provide for the construction of necessary infrastructure to connect the parties’ assets to the Advantage Pipeline System, as well as other customary closing conditions. In connection with the closing of the joint venture, the parties will enter into an operating and administrative services agreement, a dedication agreement and a limited liability company agreement pursuant to which NMS will be the operator of the Advantage Pipeline System and we will commit certain volumes to the system.

Accounting Policies [Abstract]
Presentation	Presentation The accompanying consolidated financial statements for periods prior to September 20, 2016 represent the Contributed Businesses as the accounting Predecessor to the Partnership, presented on a carve-out basis of Noble’s historical ownership of the Predecessor. The Predecessor financial statements have been prepared from the separate records maintained by Noble and may not necessarily be indicative of the actual results of operations that might have occurred if the Predecessor had been operated separately during the periods reported. Because a direct ownership relationship did not exist among the businesses comprising the Predecessor, the net investment in the Predecessor is shown as Parent Net Investment, in lieu of partners' equity, in the accompanying Consolidated Balance Sheet and Consolidated Statements of Changes in Equity for years prior to December 31, 2016. Certain prior-period amounts have been reclassified to conform to the current-period presentation. The Partnership has no items of other comprehensive income or loss; therefore, its net income is identical to its comprehensive income.
Consolidation, Noncontrolling Interest	Consolidation Our consolidated financial statements include our accounts and the accounts of the DevCos, each of which we control as general partner. All intercompany balances and transactions have been eliminated upon consolidation. In addition, we use the cost method for our White Cliffs Interest as we have virtually no influence over its operations and financial policies. Under the cost method of accounting, we recognize cash distributions from White Cliffs Pipeline L.L.C. as investment income in our consolidated statement of operations to the extent there is net income, and record cash distributions in excess of our ratable share of earnings as return of investment, and record them as investment income in the accompanying consolidated statements of operations.
Segment Information	Segment Information Accounting policies for reportable segments are the same as those described in this footnote. Transfers between segments are accounted for at market value. We do not consider interest income and expense or income tax benefit or expense in our evaluation of the performance of reportable segments.
Consolidated VIEs	Consolidated Variable Interest Entities We have determined that the partners with equity at risk in each of the DevCos lack the authority, through voting rights or similar rights, to direct the activities that most significantly impact their economic performance; therefore, each DevCo is considered a variable interest entity, or VIE. Through our 100% ownership interest in Noble Midstream Services, LLC, a Delaware limited liability company which owns controlling interests in each of the DevCos, we have the authority to direct the activities that most significantly affect economic performance and the obligation to absorb losses or the right to receive benefits that could be potentially significant to us. Therefore, we are considered the primary beneficiary and consolidate each of the DevCos. All financial statement activity associated with our DevCos is captured within the Gathering Systems and Fresh Water Delivery reportable segments.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic and commodity price environment.
Revenue Recognition	Revenue Recognition We generate revenues primarily by charging fees on a per unit basis for gathering crude oil and natural gas, delivering and storing fresh water, and collecting, cleaning and disposing of produced water. We recognize revenue when services have been rendered, the prices are fixed or determinable, and collectibility is reasonable assured.
Property, Plant and Equipment	Property, Plant and Equipment Property and equipment primarily consists of crude oil and natural gas gathering systems, produced water collection, gathering, and cleaning systems, fresh water storage and delivery systems and crude oil treating facilities. Property and equipment is stated at the lower of of historical cost less accumulated depreciation, or fair value, if impaired. We capitalize construction-related direct labor and incremental costs, such as interest expense. Capitalized interest totaled $0.8 million in 2016 , $2.5 million in 2015 , and $1.6 million in 2014 . Maintenance and repair costs are expensed as incurred. Prior to January 1, 2015, certain assets were accounted for under the successful efforts method of accounting within Noble’s accounting policies. In January 2015, Noble changed our method of depreciation from units-of-production to the straight-line method for future accounting periods. This change is a change in accounting estimate that is effected by a change in accounting principle. When the two are inseparable, the change is accounted for as a change in accounting estimate. For assets that were converted from the unit-of-production method, their respective asset lives are 30 years from the date originally placed into service. Depreciation is computed over the asset’s estimated useful life using the straight line method based on estimated useful lives and asset salvage values. Determination of depreciation expense requires judgment regarding the estimated useful lives and salvage values of property, plant and equipment. As circumstances warrant, depreciation estimates are reviewed to determine if any changes in the underlying assumptions are necessary. The weighted average life of our long-lived assets is 30 years. The depreciation of fixed assets recorded under capital lease agreements is included in depreciation and amortization expense.
Impairment of Long-Live Assets	Impairment of Long-Lived Assets We routinely assess whether impairment indicators arise during any given quarter and have processes in place to ensure that we become aware of such indicators. Impairment indicators include, but are not limited to, sustained decreases in commodity prices, a decline in customer well results and lower throughput forecasts, and increases in construction or operating costs. In the event that impairment indicators exist, we conduct an impairment test. We evaluate our ability to recover the carrying amounts of long-lived assets and determine whether such long-lived assets have been impaired. Impairment exists when the carrying value of an asset exceeds the estimated undiscounted future cash flows expected to result from the use and eventual disposition of the asset. When the carrying amount of a long-lived asset exceeds its estimated undiscounted future cash flows, the carrying amount of the asset is reduced to its estimated fair value. Fair value may be estimated using comparable market data, a discounted cash flow method, or a combination of the two.
Asset Retirement Obligations	Asset Retirement Obligations Asset retirement obligations (ARO) consist of estimated costs of dismantlement, removal, site reclamation and similar activities associated with our property and equipment. We recognize the fair value of a liability for an ARO in the period in which it is incurred when we have an existing legal obligation associated with the retirement of our infrastructure assets and the obligation can reasonably be estimated. The associated asset retirement cost is capitalized as part of the carrying cost of the infrastructure asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as: the existence of a legal obligation for an ARO; estimated probabilities, amounts and timing of settlements; the credit-adjusted risk-free rate to be used; and inflation rates. In periods subsequent to initial measurement of the ARO, we recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flows. Revisions also result in increases or decreases in the carrying cost of the asset. Increases in the ARO liability due to passage of time impact net income as accretion expense. The related capitalized cost, including revisions thereto, is charged to expense through depreciation and amortization.
Fair Value Measurements	Fair Value Measurements We measure assets and liabilities requiring fair value presentation and disclose such amounts according to the quality of valuation inputs under the fair value hierarchy. The carrying amounts of our cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature and maturity of the instruments and use Level 1 inputs.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents include unrestricted cash on hand and investments with original maturities of three months or less at the time of purchase.
Debt Origination Fees and Expenses	Debt Origination Fees and Expenses Debt origination fees and expenses of $1.9 million associated with our Revolving Credit Facility are included in deferred charges and amortized on a straight line basis over the five -year term. Amortization is included in interest expense.
Capital Lease Obligation	Capital Lease Obligation We entered into a capital lease for a pond to be used in our fresh water delivery system. The amount of the capital lease obligation is based on the discounted present value of future minimum lease payments, and therefore does not reflect future cash lease payments. The amount due within one year equals the amount by which the capital lease obligation is expected to be reduced during the next 12 months. The lease has a discounted present value of future minimum lease payments of $4.8 million as of December 31, 2016 .
Unit-Based Compensation	Unit-Based Compensation Unit-based compensation issued to directors is recorded at grant-date fair value. Expense is recognized on a straight-line basis over the requisite service period (generally the vesting period of the award) in the consolidated statements of operations.
Concentration of Credit Risk	Concentration of Credit Risk For all periods presented, 100% of our revenues are from Noble and its affiliates.
Income Taxes	Income Taxes For the period subsequent to the Offering, our consolidated financial statements do not include a provision for income taxes as the Partnership is generally not subject to federal or state income tax. Each partner is separately taxed on its share of taxable income. For periods prior to the Offering, our consolidated financial statements include a provision for tax expense on income related to the assets that Noble contributed to the Partnership at the Offering date. Deferred federal and state income taxes were provided on temporary differences between the financial statement carrying amounts of recognized assets and liabilities and their respective tax bases as if the partnership filed tax returns as a stand-alone entity.
Litigation and Other Contingencies	Litigation and Other Contingencies We may become subject to legal proceedings, claims and liabilities that will arise in the ordinary course of business. We will accrue for losses associated with legal claims when such losses are considered probable and the amounts can be reasonably estimated.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-18: Statement of Cash Flows - Restricted Cash (ASU 2016-18). ASU 2016-18 requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. This ASU will be effective for annual and interim periods beginning after December 15, 2017, with earlier application permitted. We do not believe adoption of ASU 2016-18 will have a material impact on our statement of cash flows and related disclosures. In October 2016, the FASB issued Accounting Standards Update No. 2016-17: Consolidation - Interests Held through Related Parties That Are under Common Control (ASU 2016-17) . The update changes the process through which a reporting entity determines whether it is the primary beneficiary of a VIE. As a result, the single decision maker of a VIE uses economic exposure to determine its classification as the primary beneficiary as opposed to evaluating which party is most closely associated with the VIE. In February 2015, the FASB issued ASU 2015-02, which changed the guidance as to whether an entity is a VIE or a voting interest entity and how related parties are considered in the VIE model. Under the provisions of both Accounting Standards Updates, each DevCo is considered a VIE, and we are considered the primary beneficiary of that VIE. We have adopted these provisions, which did not have a material effect on our financial statements. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15) . ASU 2016-15 clarifies the presentation of certain cash receipts and cash payments in the statement of cash flows. ASU 2016-15 will be effective for annual and interim periods beginning after December 15, 2017, with earlier application permitted. We do not believe adoption of ASU 2016-15 will have a material impact on our statement of cash flows and related disclosures as this update pertains to classification of items and is not a change in accounting principle. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (ASU 2016-02). ASU 2016-02 requires a lessee to record a right of use asset and a corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. ASU 2016-02 is effective for all interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. In the normal course of business, we enter into capital and operating lease agreements to support our operations and may lease water-related, field-related and other assets. We are in the process of evaluating the impact of ASU 2016-02 on our financial statements and disclosures. We believe the adoption and implementation of ASU 2016-02 may have a material impact on our balance sheet resulting from an increase in both assets and liabilities relating to leasing activities. In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09), which creates Topic 606, Revenue from Contracts with Customers . In summary, the core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, ASU 2014-09 requires enhanced financial statement disclosures over revenue recognition as part of the new accounting guidance. The standard will be effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. In March 2016, the FASB released certain implementation guidance through ASU 2016-08 to clarify principal versus agent considerations. We are continuing to evaluate the provisions of ASU 2014-09 and have not yet determined the full impact it may have on our financial position and results of operations.
