Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND FORMATION OF THE PARTNERSHIP	ORGANIZATION AND FORMATION OF THE PARTNERSHIP
	Organization
	Marlin Midstream Partners, LP (the "Partnership") is a midstream energy company that offers (i) natural gas gathering, compression, dehydration, treating, processing, and hydrocarbon dew-point control and transportation services to producers, marketers and third-party pipeline companies, and (ii) crude oil transloading services to Associated Energy Services, LP ("AES"), an affiliate of the Partnership.
	The Partnership is a Delaware limited partnership, formed in April 2013 by NuDevco Partners, LLC and its affiliates (“NuDevco”). NuDevco, a sole member limited liability company formed on August 27, 2010 under the Texas Limited Liability Company Act (“TLLCA”), is an affiliate of Spark Energy Ventures, LLC (“SEV”), a sole member limited liability company formed on October 8, 2007 under the TLLCA. NuDevco and SEV are both wholly owned by W. Keith Maxwell III. SEV was the sole member of Marlin Midstream, LLC and its subsidiaries ("Marlin Midstream"), and Mr. Maxwell was the sole member of Marlin Logistics, LLC prior to the closing of the Partnership's initial public offering of 6,875,000 common units representing a 38.6% limited partner interest in the Partnership on July 31, 2013 ("IPO") as discussed below. Concurrently, with the closing of the IPO, the Partnership also executed a new credit facility as discussed below.
	In connection with the closing of the IPO, SEV contributed all of its interest in Marlin Midstream to the Partnership, and Mr. Maxwell contributed all of his interest in Marlin Logistics, LLC ("Marlin Logistics") to the Partnership, through a series of transfers of interest in entities all under the common control of Mr. Maxwell in exchange for wholly owned subsidiaries of NuDevco receiving common units and all of the Partnership’s subordinated units and incentive distribution rights. The contribution of entities, as discussed above, to the Partnership is not considered a business combination accounted for under the purchase method, as it was a transfer of assets and operations under common control and, accordingly, balances were transferred at their historical cost. The Partnership's historical condensed combined financial statements prior to the IPO are prepared using Marlin Midstream's and Marlin Logistics' historical basis in the assets and liabilities, and include all revenues, costs, assets and liabilities attributed to these entities for the periods presented. The Partnership's financial statements subsequent to the IPO are prepared on a consolidated basis.
	The Partnership’s general partner, Marlin Midstream GP, LLC manages the Partnership’s activities subject to the terms and conditions specified in the Partnership’s partnership agreement. The Partnership’s general partner is owned by NuDevco Midstream Development, LLC ("NuDevco Midstream Development"), an indirect wholly owned subsidiary of NuDevco. The operations of the general partner, in its capacity as general partner, are managed by its board of directors. Actions by the general partner that are made in its individual capacity will be made by NuDevco Midstream Development as the sole member of the Partnership's general partner and not by the board of directors of the general partner. The partnership's general partner will not be elected by the Partnership's unitholders and will not be subject to re-election on a regular basis in the future. The officers of the general partner will manage the day-to-day affairs of the Partnership's business.
	Marlin Midstream was formed November 26, 2002 as a sole member limited liability company under the TLLCA. Marlin Midstream is a midstream energy company offering the following midstream services: natural gas gathering, compression, dehydration, treating, processing and hydrocarbon dew-point control and transportation services to producers, third-party pipeline companies and marketers.
	Marlin Logistics, formerly known as FuelCo Energy, LLC, was formed August 26, 2010 as a sole member limited liability company under the TLLCA. Marlin Logistics is a crude oil logistics company that offers crude oil transloading services.
	As a company with less than $1.0 billion in revenues during its last fiscal year, the Partnership qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. An emerging growth company may take advantage of specified reduced reporting and other regulatory requirements for up to five years that are otherwise applicable generally to public companies, such as no requirement to provide selected financial data in their annual reports for any period prior to the earliest audited period presented in connection with their first registration statement under the Securities Act or the Exchange Act that became effective.
	The Partnership will remain an emerging growth company for five years unless, prior to that time, annual revenues total more than $1.0 billion, have a market value for the common units held by non-affiliates of more than $700 million as of June 30 of the year a determination is made whether the Partnership deemed to be a “large accelerated filer,” as defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or issue more than $1.0 billion of non-convertible debt over a three-year period.
	As a result of our election to avail ourselves of certain provisions of the JOBS Act, the information that we provide may be different than what you may receive from other public companies in which you hold an equity interest.
	Initial Public Offering of Marlin Midstream Partners, LP
	On July 31, 2013, the Partnership completed the IPO of 6,875,000 common units, representing a 38.6% limited partner interest, to the public for $20.00 per common unit, less an underwriting discount of $1.20 per common unit. After the closing of the IPO, substantially all the Partnership's gross margin is generated under fee-based commercial agreements, the substantial majority of which have minimum volume commitments.
	Net proceeds to the Partnership from the IPO were $125.3 million, after underwriting discount, structuring fees and other direct IPO costs. Using those proceeds, the Partnership repaid its existing credit facility of approximately $121.9 million and the outstanding revolving credit facility of approximately $10.0 million, and settled its existing interest rate swap liability of approximately $0.1 million.
	At the consummation of the IPO, the amount of common, subordinated, and general partner units is summarized in the table below:
		Number of units		Limited Partner
		at July 31, 2013		Interest
	Publicly held common units	6,875,000		38.60%
	Common units held by NuDevco	1,849,545		10.40%
	Subordinated units held by NuDevco	8,724,545		49.00%
	General partner units	356,104		2.00%
	Total	17,805,194		100.00%
	There have been no subsequent issuances of common units.
	Our Fee-Based Commercial Agreements
	Prior to the IPO, the Partnership generated revenues primarily under keep-whole and other commodity-based gathering and processing agreements with third parties and its affiliates. At the closing of the IPO, the Partnership terminated the existing commodity-based gas gathering and processing agreement with AES, assigned to AES all of the remaining keep-whole and other commodity-based gathering and processing agreements with third party customers and entered into a new three-year fee-based gathering and processing agreement with AES with a minimum volume commitment and annual inflation adjustments.
	Following the closing of the IPO, the Partnership has multiple fee-based commercial agreements in place with Anadarko Petroleum Corporation (“Anadarko”) and AES, substantially all of which include minimum volume commitments and annual inflation adjustments that will initially be the source of a substantial portion of the Partnership's revenues.
	The following table summarizes certain information regarding our fee-based commercial agreements with Anadarko and AES following the closing of the IPO:
		Current Term	Renewal	Minimum  Volume
		Expiration		Commitment
	Anadarko Panola County Agreement I	July 31, 2015	Year-to-year	Yes
	Anadarko Panola County Agreement II	March 31, 2019	Month-to-month	Yes
	AES Panola County Agreement	Three years	Year-to-year	80 MMcf/d
	Anadarko Tyler County Agreement	October 31, 2015	Year-to-year	No
	AES Wildcat Skid Transloading Agreement	Three years	Year-to-year	7,600 Bbls/d
	AES Big Horn Skid Transloading Agreement	Three years	Year-to-year	7,600 Bbls/d
	AES Master Ladder Transloading Agreement (1)	Three years	Year-to-year	3,780 Bbls/d
	(1) At the closing of the IPO, the Partnership operated three ladder transloaders: one located at the Big Horn facility and two located at the Wildcat Facility. The total minimum volume commitment at the Big Horn facility is 8,860 Bbls/d and the total minimum volume commitment at the Wildcat facility is 10,120 Bbls/d.
	Credit Facility
	Concurrently with the closing of the IPO, the Partnership entered into a new $50.0 million senior secured revolving credit facility, which matures on July 31, 2017. If no event of default has occurred, the Partnership has the right, subject to approval by the administrative agent and certain lenders, to increase the borrowing capacity under the revolving credit facility to up to $150.0 million. The new revolving credit facility is available to fund expansions, acquisitions and working capital requirements for operations and general corporate purposes. At the closing of the IPO, the Partnership borrowed $25.0 million under the new revolving credit facility. At September 30, 2013, $8.5 million was outstanding under the new revolving credit facility.
	At our election, interest will be generally determined by reference to:
	•	the Eurodollar rate plus an applicable margin between 3.0% and 3.75% per annum (based upon the prevailing senior secured leverage ratio); or
	•	the alternate base rate plus an applicable margin between 2.0% and 2.75% per annum (based upon the prevailing senior secured leverage ratio). The alternate base rate is equal to the highest of Société Générale's prime rate, the federal funds rate plus 0.5% per annum or the reference Eurodollar rate plus 1.0%.
	Our new revolving credit facility is secured by the capital stock of our present and future subsidiaries, all of our and our subsidiaries' present and future property and assets (real and personal), control agreements relating to our and our subsidiaries' bank accounts and other instruments, investment property, general intangibles and contract rights, including rights under any agreements with AES or Anadarko.
	Our new revolving credit facility also contains covenants that, among other things, require us to maintain specified ratios or conditions. We must maintain a consolidated senior secured leverage ratio, consisting of consolidated indebtedness under our new revolving credit facility to consolidated EBITDA of not more than 4.0 to 1.0, as of the last day of each fiscal quarter. In addition, we must maintain a consolidated interest coverage ratio, consisting of our consolidated EBITDA minus capital expenditures to our consolidated interest expense, letter of credit fees and commitment fees of not less than 2.5 to 1.0, as of the last day of each fiscal quarter.
	In addition, our new revolving credit facility contains affirmative covenants that are customary for credit facilities of this type. The covenants will include delivery of financial statements and other information (including any filings made with the SEC), maintenance of property and insurance, payment of taxes and obligations, material compliance with laws, inspection of property, books and records and audits, use of proceeds, payments to bank blocked accounts, notice of defaults and certain other customary matters. See also Note 6.
	Other Transactions in Connection with the Consummation of the IPO:
	On July 31, 2013, in connection with the closing of the IPO, the following transactions occurred:
	•	the Partnership's general partner maintained its 2.0% general partner interest, and all of the Partnership's incentive distribution rights were issued to Marlin IDR Holdings, LLC;
	•	the Partnership issued 1,849,545 common units and 8,724,545 subordinated units to NuDevco Midstream Development for the contributions by SEV and Mr. Maxwell, representing a 49.0% limited partner interest in the Partnership;
	•	the Partnership transferred to affiliates of NuDevco (i) the Partnership's 50% interest in a CO2 processing facility located in Monell, Wyoming, (ii) certain transloading assets and purchase commitments owned by Marlin Logistics that are not currently under a service contract, (iii) certain property, plant and equipment and other equipment not yet in service and (iv) certain other immaterial contracts;
	•	NuDevco assumed $11.7 million of the non-current accounts payable balance owed by Marlin Midstream to affiliates of SEV and Marlin Midstream was released from such obligations; and
	•	the Partnership entered into an omnibus agreement with the general partner and its affiliates that addresses (i) the management and administrative services to be provided by NuDevco to the Partnership and the corresponding fees and expense reimbursements to be paid to NuDevco in connection therewith, (ii) the indemnification obligations between NuDevco and the Partnership for environmental and other liabilities and the operation of assets and (iii) the Partnership's right of first offer on certain of NuDevco Midstream Development's midstream energy assets.

BASIS OF PRESENTATION	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION
	The condensed consolidated and combined financial statements have been prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC").
	In preparing financial statements in accordance with GAAP, management makes informed judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses. Management evaluates its estimates and related assumptions regularly, utilizing historical experience and other methods considered reasonable under the particular circumstances. Changes in facts and circumstances or additional information may result in revised estimates and actual results may differ from these estimates. Effects on the business, financial condition and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revision become known. The information furnished herein reflects all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the condensed consolidated and combined financial statements. Operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of the results which may be expected for the full year or for any interim period. The condensed consolidated and combined financial statements include the accounts of the Partnership and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
	Certain information and note disclosures commonly included in annual financial statements have been condensed or omitted pursuant to the rules and regulations of the SEC. Accordingly, the accompanying condensed consolidated and combined financial statements and notes should be read in conjunction with the Partnership’s prospectus relating to the IPO, as filed with the SEC on July 29, 2013. Management believes that the disclosures made are adequate to make the information not misleading.
	The accompanying condensed consolidated and combined financial statements have been prepared in accordance with Regulation S-X, Article 3, General Instructions as to Financial Statements and Staff Accounting Bulletin ("SAB") Topic 1-B, Allocations of Expenses and Related Disclosures in Financial Statements of Subsidiaries, Divisions or Lesser Business Components of Another Entity. Certain expenses incurred by SEV are only indirectly attributable to its ownership of Marlin Midstream prior to the IPO. As a result, certain assumptions and estimates are made in order to allocate a reasonable share of such expenses to the Partnership, so that the accompanying condensed consolidated and combined financial statements reflect substantially all costs of doing business. The allocations and related estimates and assumptions are described more fully in Note 11 ("Transactions with Affiliates"), which the Partnership believes are reasonable.
	SEV has allocated various corporate overhead expenses to the Partnership based on percentage of departmental usage, wages or headcount. These allocations are not necessarily indicative of the cost that the Partnership would have incurred had it operated as an independent stand-alone entity. As such, the condensed consolidated and combined financial statements do not fully reflect what the Partnership's financial position, results of operations and cash flows would have been had the Partnership operated as a stand-alone company during the periods presented.
	At the closing of the IPO, the Partnership entered into an omnibus agreement with NuDevco and its affiliates which addresses the management and administrative services to be provided by NuDevco to the Partnership and the corresponding fees and expense reimbursements to be paid to NuDevco in connection therewith. Under the omnibus agreement, the Partnership pays an annual fee, initially in the amount of $0.6 million, for executive management services and is allocated general and administrative and operating expenses that are directly attributable to the Partnership.
	Marlin Midstream has also historically relied upon SEV and its affiliates as a participant in SEV's credit facility. As a result, historical combined financial information is not necessarily indicative of what the Partnership's results of operations, financial position and cash flows will be in the future.
	Subsequent Events
	Subsequent events have been evaluated through the date these financial statements are issued. Any material subsequent events that occurred prior to such date have been properly recognized or disclosed in the condensed consolidated and combined financial statements.
	Segment Reporting
	The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 280, Segment Reporting, established standards for entities to report information about the operating segments and geographic areas in which they operate. The Partnership operates two segments: the gathering and processing segment and the crude oil logistics segment. All of the Partnership's operations are located in the United States.
	Net Income Per Unit
	The Partnership has omitted net income per unit for all historical periods prior to the IPO because the Partnership operated under a sole member equity structure for the prior years presented, which is different than the capital structure resulting from the consummation of the IPO and, as a result, the per unit data for periods prior to the IPO would not be meaningful to investors.
	The net income per unit figures on the condensed consolidated and combined Statements of Operations are based on the net income of the Partnership after the closing of the IPO on July 31, 2013 through September 30, 2013, since this is the amount of net income that is attributable to the newly issued Partnership units.
	Recent Accounting Pronouncements
	In December 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-11, Disclosures about Offsetting Assets and Liabilities ("ASU 2011-11"). ASU 2011-11 retains the existing offsetting requirements and enhances the disclosure requirements to allow investors to better compare financial statements prepared under GAAP with those prepared under International Financial Reporting Standards ("IRFS"). On January 31, 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities ("ASU 2013-01"). ASU 2013-01 limits the scope of the new balance sheet offsetting disclosure to derivatives, repurchase agreements and securities lending transactions. Both standards are effective for interim and annual periods beginning January 1, 2013 and should be applied retrospectively. The Partnership adopted both standards on January 1, 2013. The standards did not have an effect on the Partnership's condensed financial statement footnotes, as the Partnership's derivative financial instruments are not presented on a net basis in the Partnership' s condensed consolidated and combined Balance Sheets.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting Amounts Reclassified Out of Accumulated Comprehensive Income ("ASU 2013-02"), related to the reporting of amounts reclassified out of accumulated other comprehensive income.This guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the related notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period .For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The guidance is effective for annual reporting periods, and interim period s within those years, beginning after December 15, 2012. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. As such, the Partnership can delay the adoption of certain accounting standards until these standards would otherwise apply to private companies. The Partnership has elected to delay such adoption of new or revised accounting standards, and as a result, the Partnership will not adopt ASU 2013-02 until interim periods in 2014 as required by nonpublic entities.

Equity [Abstract]
PARTNERSHIP EQUITY AND DISTRIBUTIONS	PARTNERSHIP EQUITY AND DISTRIBUTIONS
	As discussed in Note 1, on July 31, 2013, the Partnership completed the IPO of 6,875,000 common units, representing a 38.6% limited partner interest, to the public for $20.00 per common unit, less an underwriting discount of $1.20 per common unit. Additionally, 1,849,545 common units, representing a 10.4% limited partner interest, and 8,724,545 subordinated units, representing a 49.0% interest, were transferred to NuDevco Midstream Development, and 356,104 general partner units, representing a 2.0% general partner interest, were transferred to Marlin Midstream GP, LLC.
	Distributable Cash and Distributions
	The partnership agreement requires the Partnership to distribute all available cash to unitholders of record, as of the applicable record date, no later than 45 days after the end of each quarter, beginning with the quarter ending September 30, 2013. For the quarter ending September 30, 2013, the amount of the distribution was adjusted based on the net income of the Partnership for the period from the IPO date of July 31, 2013 through September 30, 2013.
	Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter:
	•less, the amount of cash reserves established by the General Partner to:
	◦	provide for the proper conduct of the business (including reserves for future capital expenditures and anticipated future debt service requirements and for anticipated shortfalls on future minimum commitment payments to which prior credits may be applied);
	◦	comply with applicable law, any of our debt instruments or other agreements; or
	◦	provide funds for distributions to unitholders and to the general partner for any one or more of the next four quarters (provided that the general partner may not establish cash reserves for distributions if the effect of the establishment of such reserves will prevent us from distributing the minimum quarterly distribution on all common units and any cumulative arrearages on such common units for the current quarter);
	•	plus, if the general partner so determines, all or any portion of the cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made subsequent to the end of such quarter.
	On October 18, 2013, the Partnership declared the following cash distributions to its unitholders of record for the periods presented to be paid on November 4, 2013:
	In Thousands, except per-unit amounts		Total Quarterly		Total Cash		Date of
	Quarter ended:		Distribution per Unit		Distribution		Distribution
	September 30, 2013	-1	$	0.23	$	4,095.20	4-Nov-13
	30-Jun-13	-2	—		—		—
	(1) This distribution represents a prorated amount of the full minimum quarterly distribution of $0.35 per unit for each whole quarter based on the number of days between the closing of the Partnership's IPO on July 31, 2013 and September 30, 2013.
	(2) No distributions were declared for the quarter ending June 30, 2013. This quarter was included in the results reported in the report on Form 10-Q for the second quarter ending June 30, 2013; however, this quarter was prior to the completion of the IPO.
	Subordinated Units and Common Units Held by NuDevco Midstream Development
	NuDevco Midstream Development owns 100% of the interest in the Partnership's general partner, which owns 2.0% of the Partnership, a 10.4% limited partner interest and 49.0% subordinated limited partner interest in the Partnership. The Partnership agreement provides that, during the subordination period described below, the subordinated units will not be entitled to receive any distributions until the common units have received the minimum quarterly distribution plus any arrearages from prior quarters. No arrearages accrue or are payable on the subordinated units.
	Except as described below, the subordination period began on the closing date of the IPO and extends until the first business day following the distribution of available cash in respect of any quarter beginning after September 30, 2016, that each of the following tests are met:
	•	distributions of available cash from operating surplus on each of the outstanding common units, subordinated units and general partner units equaled or exceeded $1.40 (the annualized minimum quarterly distribution), for each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date;
	•	the adjusted operating surplus generated during each of the three consecutive, non-overlapping four-quarter periods immediately preceding that date equaled or exceeded the sum of $1.40 (the annualized minimum quarterly distribution) on all of the outstanding common units, subordinated units and general partner units during those periods on a fully diluted basis; and
	•	there are no arrearages in payment of the minimum quarterly distribution on the common units.

NET INCOME PER LIMITED PARTNER UNIT [Abstract]
NET INCOME PER LIMITED PARTNER UNIT	NET INCOME PER UNIT
	The net income per unit figures on the condensed consolidated and combined Statements of Operations are based on the net income of the Partnership after the closing of the offering on July 31, 2013 through September 30, 2013, since this is the amount of net income that is attributable to the newly issued common units.
	The Partnership's net income for periods subsequent to the IPO is allocated to the general partner and the limited partners in accordance with their respective ownership percentages and, when applicable, giving effect to incentive distributions allocable to the general partner. Basic and diluted net income per unit is calculated by dividing the partner's interest in net income by the weighted average number of units outstanding during the period.
	The calculation of net income per limited partner unit is the same for the three months and nine months ended September 30, 2013 due to the closing of the IPO in the three months ended September 30, 2013. As a result, no income from the seven months ended July 31, 2013 is allocated to the limited partner units that were issued on July 31, 2013.
	The following table illustrates the Partnership’s calculation of net income per unit for common and subordinated partner units

	The Partnership’s principal assets consist of two related natural gas processing facilities located in Panola County, Texas, a natural gas processing facility located in Tyler County, Texas, two natural gas gathering systems connected to its Panola County processing facilities and two NGL transportation pipelines that connect its Panola County and Tyler County processing facilities to third party NGL pipelines.
	At the completion of the IPO, the Partnership transferred the Partnership's 50% interest in the CO2 processing facility located in Monell, Wyoming to affiliates of NuDevco. As such, subsequent to the closing of the IPO, the Partnership incurs no revenues or expenses associated with the Monell facility. The Partnership was responsible for the design and construction of the Monell facility. Anadarko was designated as an operator of the Monell facility who has exclusive right to operate the facility until terminated by unanimous vote of the owners. Revenue generated from and capital expenditures and operating expenses incurred in connection with the operation of the plant were allocated on a pro-rata basis in proportion to each owner's ownership interest. The Partnership recorded its proportional cost of the Monell facility and its share of revenues and expenses in its condensed combined financial statements, as earned and incurred prior to the closing of the IPO, respectively.
	For the three months and nine months ended September 30, 2013 and 2012, the Partnership recorded revenues of $0.1 million and $0.3 million and $0.1 million and $1.0 million, respectively, and recorded expenses of $0.1 million and $0.1 million and $0.3 million and $0.3 million, respectively, attributable to the Monell facility in connection with the collaborative arrangement. These revenues are recorded in natural gas, NGLs and condensate revenue and the expenses are recorded in operation and maintenance in the condensed consolidated and combined Statements of Operations.
	As of December 31, 2012, property, plant and equipment, net recorded in the condensed combined Balance Sheet attributable to the Monell facility was $3.5 million. On July 31, 2013, in connection with the IPO, the Partnership transferred property, plant and equipment, net of $3.2 million attributable to the Monell facility to affiliates of NuDevco.
	The cost of property, plant and equipment classified as “Construction-in-progress” is excluded from costs being depreciated. These amounts represent property that is not yet suitable to be placed into productive service as of the respective balance sheet date.
	Depreciation expense was $2.1 million and $1.9 million for the three months ended and $6.1 million and $5.7 million for the nine months ended September 30, 2013 and 2012, respectively.

	Total long-term debt		$	8,500		$	120,250
	In October 2007, SEV and all of its subsidiaries (collectively, the “Borrowers”), including Marlin Midstream, entered into a credit agreement, which provided for a working capital facility, a term loan and a revolving credit facility (the “Credit Agreement”), as co-borrowers and were jointly and severally liable for amounts borrowed under the Credit Agreement. The Credit Agreement was secured by substantially all of the assets of SEV and its subsidiaries, including all of Marlin Midstream’s assets.
	The Credit Agreement was amended on May 30, 2008 to provide for a $177.5 million working capital facility, a $100.0 million term loan, and a $35.0 million revolving credit facility. On January 24, 2011, the Borrowers amended and restated the Credit Agreement (the “Fifth Amended Credit Agreement”) to decrease the working capital facility to $150.0 million, to increase the term loan to $130.0 million and to eliminate the revolving credit facility.
	On December 17, 2012, the Borrowers amended and restated the Fifth Amended Credit Agreement to decrease the working capital facility to $70.0 million, to decrease the term loan to $125.0 million and to reinstate the revolving credit facility in the amount of $30.0 million (the “Sixth Amended Credit Agreement”). The Sixth Amended Credit Agreement was scheduled to mature on December 17, 2014.
	Although Marlin Midstream was jointly and severally liable for SEV’s borrowings, Marlin Midstream did not historically have access to the working capital facility, but was the primary recipient of the proceeds from the term loan and revolving credit facility.
	The Partnership applied ASU 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date (“ASU 2013-04”), which prescribes the accounting for joint and several liability arrangements. This guidance requires an entity to measure its obligation resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. Based on the Sixth Amended Credit Agreement and understanding among the Borrowers, the term loan and the revolving credit facility were assigned specifically to Marlin Midstream. The Partnership recognized the proceeds from the term loan and the revolving credit facility on its condensed combined Balance Sheet at December 31, 2012 in the amount of $126.5 million, which represented the amounts Marlin Midstream agreed with the other borrowers to pay, and the amounts Marlin Midstream expected to pay.
	Term Loan and Revolving Credit Facility
	Term loan
	The term loan consisted of outstanding borrowings of $125.0 million as of December 17, 2012 under the Sixth Amended Credit Agreement. The term loan required quarterly principal payments of $1.6 million to maturity, with the balance of $112.5 million due on December 17, 2014.
	Under the Sixth Amended Credit Agreement, Marlin Midstream may have elected to have loans under the term loan bear interest either (i) at a Eurodollar based rate plus a margin ranging from 3.50% to 4.25% depending on SEV’s consolidated funded indebtedness ratio then in effect, or (ii) at a base rate loan plus a margin ranging from 2.50% to 3.25% depending on SEV’s consolidated funded indebtedness ratio then in effect.
	The interest rate for the term loan was 3.96% at December 31, 2012. This loan was repaid on July 31, 2013 with funds received from the IPO and borrowings under the Partnership's new credit facility.
	Revolving credit facility
	The revolving credit facility was reinstated on December 17, 2012 with a borrowing capacity of $30.0 million as part of the Sixth Amended Credit Agreement. The revolving credit facility outstanding principal was due on December 31, 2014. The outstanding balance on the revolving credit facility at December 31, 2012 was $1.5 million.
	The unused portion of the revolving credit facility was subject to a commitment fee of 0.50%. The interest rate was 3.96% at December 31, 2012. The Sixth Amended Credit Facility was repaid on July 31, 2013 with funds received from the IPO and borrowings under the Partnership's new credit facility.
	New Credit Facility
	Concurrently with the closing of our IPO, the Partnership entered into a new $50.0 million senior secured revolving credit facility, which matures on July 31, 2017. If no event of default has occurred, the Partnership has the right, subject to approval by the administrative agent and certain lenders, to increase the borrowing capacity under the new revolving credit facility to up to $150.0 million. The new credit facility is available to fund expansions, acquisitions and working capital requirements for our operations and general Partnership purposes.
	At the Partnership's election, interest will be generally determined by reference to:
	•	the Eurodollar rate plus an applicable margin between 3.0% and 3.75% per annum (based upon the prevailing senior secured leverage ratio); or
	•	the alternate base rate plus an applicable margin between 2.0% and 2.75% per annum (based upon the prevailing senior secured leverage ratio). The alternate base rate is equal to the highest of Société Générale’s prime rate, the federal funds rate plus 0.5% per annum or the reference Eurodollar rate plus 1.0%.
	The new revolving credit facility is secured by the capital stock of our present and future subsidiaries, all of our and our subsidiaries’ present and future property and assets (real and personal) control agreements relating to our and our subsidiaries’ bank accounts and collateral assignments of our and our subsidiaries’ material construction, ownership and operation agreements, including any agreements with AES or Anadarko.
	At the closing of the IPO, the Partnership borrowed $25.0 million under the new revolving credit facility, a portion of which, along with the proceeds from the IPO, were used to repay approximately $131.9 million of outstanding borrowings under the previous credit facility. Immediately upon repayment, the previous credit facility was terminated. At September 30, 2013, the Partnership had $8.5 million outstanding on the senior secured revolving credit facility.
	The new revolving credit facility contains various operational and financial covenants that are typical for these types of agreements and may restrict the Partnership from assuming certain types of debt, granting liens, selling substantial portions of assets, transferring assets, merging, dissolving, or otherwise materially changing the character of the business. As of September 31, 2013, the Partnership was in compliance with all debt covenants.
	Debt Maturities
	Principal amounts of long-term debt under the new senior secured revolving credit facility mature on July 31, 2017.
	Deferred Financing Costs
	Deferred financing costs were $1.1 million and $1.2 million as of September 30, 2013 and December 31, 2012, respectively. Of these amounts, $0.3 million and $0.7 million are included in other current assets within the condensed consolidated and combined Balance Sheets at September 30, 2013 and December 31, 2012 , respectively, and $0.8 million and $0.5 million are included in other assets within the condensed consolidated and combined Balance Sheets at September 30, 2013 and December 31, 2012, respectively, based on the term of the related debt obligations.
	Amortization of deferred financing costs was $0.1 million and $0.1 million for the three months ended September 30, 2013 and 2012, respectively, and $0.4 million and $0.3 million for the nine months ended September 30, 2013 and 2012, respectively. Amortization of deferred financing costs is recorded in interest expense, net of amounts capitalized, in the condensed consolidated and combined Statements of Operations.
	In conjunction with executing the Sixth Amended Credit Agreement in December 2012, the Partnership paid $1.0 million of financing costs, of which $0.9 million was capitalized and $0.1 million was expensed immediately in general and administrative expenses in the condensed consolidated and combined Statements of Operations. Simultaneously, the Partnership expensed $0.2 million of existing unamortized deferred financing costs related to the Fifth Amended Credit Agreement, which is recorded in interest expense in the condensed consolidated and combined Statements of Operations.
	In conjunction with executing the new revolving credit facility on July 31, 2013, the Partnership paid $1.1 million of financing costs, all of which were capitalized. Simultaneously, the Partnership expensed $0.8 million of existing unamortized deferred financing costs related to the Sixth Amended Credit Agreement, which is recorded in interest expense in the condensed consolidated and combined Statements of Operations.
	Interest Expense
	A reconciliation of total interest expense to “interest expense, net of amounts capitalized” as reported in the condensed consolidated and combined Statements of Operations for the three and nine months ended September 30, 2013 and 2012 is as follows:

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS
	The Partnership historically used interest-rate related derivative instruments to manage its exposure related to changes in interest rates on its variable rate debt instruments and periodically used commodity derivatives to manage its exposure to commodity price fluctuations. The Partnership does not enter into speculative or trading derivative instruments.
	By using derivative financial instruments to hedge exposures to changes in interest rates and commodity prices, the Partnership exposed itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract was positive, the counterparty owed the Partnership, which created credit risk for the Partnership. When the fair value of the derivative contract was negative, the Partnership owed the counterparty, and therefore, the Partnership was not exposed to the counterparty’s credit risk in those circumstances. The Partnership minimized counterparty credit risk in derivative instruments by entering into transactions with high-quality counterparties. The derivative instruments entered into by the Partnership did not contain credit-risk-related contingent features.
	Market risk is the adverse effect on the fair value of a derivative instrument that results from a change in the underlying interest rates or commodity prices. For derivative instruments where hedge accounting is utilized, unrealized gains and losses recognized on derivative instruments due to changes in the fair value of the derivative instruments will offset corresponding realized gains and losses on the related hedged item. Unrealized gains or losses are recognized on the derivative instruments, to the extent the hedge is effective, are deferred in other comprehensive income, and recognized in income when the underlying hedged transaction is recognized. For derivative instruments where hedge accounting is not utilized, unrealized gains and losses due to changes in the fair value of the derivative instruments are recognized currently in earnings and may not fully offset current period realized gain or losses on the related hedged item. The market risk associated with interest rate and commodity price contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.
	The Partnership maintains a commodity-price-risk management strategy that allows for the use of derivative instruments to minimize significant unanticipated earnings fluctuations caused by commodity-price-volatility. Since the Partnership has entered into primarily fee-based contracts, the Partnership did not have any outstanding commodity-price related derivative instruments as of September 30, 2013.
	Commodity Derivatives
	The Partnership was historically exposed to market risk from changes in energy commodity prices within its operations. The Partnership sold NGL volumes received as compensation for processing services and also bought natural gas to satisfy the required fuel and shrink needed to recover NGLs. To reduce exposure to a decrease in revenues from fluctuations in NGL market prices or increases in costs and operating expenses from fluctuations in natural gas market prices, the Partnership, at times, entered into NGL or natural gas derivative contracts to mitigate the price risk on forecasted sales of NGLs and purchases of natural gas. The Partnership’s NGL derivatives were designated as cash flow hedges, while its natural gas derivatives did not qualify for hedge accounting despite hedging its future cash flows on an economic basis.
	Changes in the fair value of commodity derivatives that were not designated as cash flow hedges were recorded within cost of revenues—affiliates in the condensed consolidated combined Statements of Operations. Changes in the fair value of designated cash flow hedges, to the extent effective, were deferred in other comprehensive income and reclassified into earnings in the same period or periods in which the hedged forecasted purchases or sales affected earnings, or when it was probable that the hedged forecasted transaction would not occur by the end of the originally specified time period. Settlements of derivatives were included in cash flows from operating activities for the Partnership. The Partnership has no outstanding commodity derivative instruments at September 30, 2013 or December 31, 2012.
	Interest Rate Swap
	On January 24, 2011, Marlin Midstream entered into an interest rate swap ("2011 Swap"). The 2011 Swap paid a fixed rate and received a floating rate in order to fix the interest rate on the Partnership’s term loan and was scheduled to mature on January 24, 2014. The notional amount of the 2011 Swap as of December 31, 2011 was $100.0 million.
	On December 17, 2012, Marlin Midstream terminated the 2011 Swap and entered into a new interest rate swap ("2012 Swap") in order to fix a portion of the interest rate on Marlin Midstream’s amended term loan. Marlin Midstream paid a fixed rate and received a floating rate under the 2012 Swap. The maturity date of the 2012 Swap was December 17, 2014, and the notional amount of the 2012 Swap at December 31, 2012 was $62.5 million. On July 31, 2013, in connection with the Partnership's IPO, the 2012 Swap was settled for approximately $0.1 million.
	Marlin Midstream’s interest rate swaps did not meet the criteria necessary to qualify for cash flow hedge accounting and were recorded at fair value at each reporting period with the associated unrealized gain or loss recorded in gain (loss) on interest rate swap in the condensed combined Statements of Operations.
	The following table presents the fair value of the Partnership’s derivative assets and liabilities including amounts for designated and undesignated hedge activities:

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS
	FASB ASC 820, Fair Value Measurement, established a single authoritative definition of fair value when accounting rules require the use of fair value, set out a framework for measuring fair value and required additional disclosures about fair value measurements. The standard clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The standard utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
	•	Level 1—Quoted prices in active markets for identical assets or liabilities.
	•	Level 2—Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities).
	•	Level 3—Significant unobservable inputs (including the Partnership’s own assumptions in determining fair value).
	When the Partnership is required to measure fair value, and there is not a market-observable price for the asset or liability or a market-observable price for a similar asset or liability, the Partnership utilizes the cost, income, or market valuation approach depending on the quality of information available to support management’s assumptions.
	The following table provides the Partnership’s carrying values of financial instruments measured at fair value on a recurring basis, by input level. Financial instruments are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels. The Partnership has not presented its derivative assets and liabilities on a net basis in the condensed consolidated and combined Balance Sheets and has not been required to maintain any cash collateral offset for any of its derivative financial instruments.

	The Partnership had no financial instruments at September 30, 2013. At the IPO date, the Partnership settled the outstanding interest rate swap.
	The partnership had no financial instruments measured using Level 1 or 3 at December 31, 2012. The Partnership had no transfers of assets or liabilities between any of the above levels during 2013 and 2012. The interest rate swap derivatives were valued using current forward interest rates as quoted by brokers to be received in a cash market. The Partnership also considered counterparty credit rating, which is internally estimated in determining a credit adjustment. The credit adjustment was not material as of December 31, 2012.
	The estimated fair value of accounts receivable, accounts payable, and accrued liabilities approximate their carrying values due to their short-term nature. The estimated fair value of accounts receivable—affiliates and accounts payable—affiliates cannot be determined due to the related party nature of these items. The estimated fair value of the Partnership’s outstanding long-term debt approximates carrying value due to the variable rate nature of the Partnership’s long-term debt.

	In 2012, the Partnership entered into an agreement to purchase railcars with a future cash obligation of $12.6 million due in 2014. On July 31, 2013, in connection with the closing of the IPO, the Partnership transferred its deposit on the railcars of $0.7 million and assigned the future obligation to NuDevco Midstream Development. The deposit on railcars was recorded in other current assets at December 31, 2012 in the condensed combined Balance Sheet.
	The Partnership has reserved capacity of 3,500 barrels a day at a third-party fractionator. If the Partnership fails to deliver 95% of the reserved capacity, the Partnership is obligated to pay a fixed fee. The maximum total fixed fee that the Partnership would be obligated to pay is approximately $2.2 million per year through the end of the contract, which expires April 30, 2015. The Partnership recorded $0.4 million of expense for the nine months ended September 30, 2013 of accrued deficiency payments for under delivery of volumes. No payments were accrued or paid in 2012.
	From time to time, the Partnership may be involved in legal, tax, regulatory and other proceedings in the ordinary course of business.

Related Party Transactions [Abstract]
TRANSACTIONS WITH AFFILIATES	TRANSACTIONS WITH AFFILIATES
	From time to time, the Partnership enters into transactions with SEV related affiliates that have a common owner with the Partnership in order to reduce risk, create strategic alliances and supply or receive goods and services to these SEV related affiliates. See also Note 1 for a discussion of transactions with affiliates coinciding with the closing of the IPO in July 2013.
	Accounts receivable from and accounts payable to affiliates
	The Partnership had receivables due from affiliates of $3.4 million and $0.1 million at September 30, 2013 and December 31, 2012, respectively. At September 30, 2013, receivables due from affiliates primarily related to our fee-based gathering and processing agreement with a subsidiary of SEV, and our fee-based transloading services agreement with a subsidiary of SEV. Payables to affiliates were $2.0 million and $4.0 million at September 30, 2013 and December 31, 2012, respectively. At September 30, 2013, payables to affiliates primarily related to settlements under our gathering and processing agreement with a subsidiary of SEV and reimbursement to an affiliate of NuDevco for certain general and administrative and operating costs under the omnibus agreement with NuDevco. At December 31, 2012, payables to affiliates primarily related to gas purchases from affiliates to satisfy requirements under certain keep-whole contracts.
	On April 8, 2013, SEV and the Partnership entered an Acknowledgment and Agreement, whereby SEV and the Partnership acknowledged and agreed that $14.7 million of the accounts payable-affiliates balance (the "Outstanding Amount") as of March 31, 2013 (i) was not required to be paid sooner than March 31, 2014, (ii) that no interest shall accrue on the Outstanding Amount or any future accounts payable-affiliates balances owed by the Partnership, and (iii) the Acknowledgment and Agreement does not preclude the Partnership from paying the Outstanding Amount prior to March 31, 2014. Accordingly, $14.7 million was reclassified to long-term accounts payable-affiliates in the December 31, 2012 condensed combined Balance Sheet.
	On April 25, 2013, the Partnership received a capital contribution of $3.0 million from its sole member. On April 26, 2013, the Partnership paid $3.0 million of the Outstanding Amount, reducing the Outstanding Amount to $11.7 million.
	On June 3, 2013 SEV and the Partnership entered into a revised Acknowledgment and Agreement, whereby SEV and the Partnership acknowledged and agreed that $11.7 million of the accounts payable-affiliates balance (the "Remaining Outstanding Amount") as of March 31, 2013 (i) was not required to be paid sooner than July 31, 2014, (ii) that no interest shall accrue on the Remaining Outstanding Amount or any future accounts payable­ affiliates balances owed by the Partnership, and (iii) the Acknowledgment and Agreement does not preclude the Partnership from paying the Remaining Outstanding Amount prior to July 31, 2014.
	In July 2013, in connection with the closing of the IPO, NuDevco Midstream Development assumed the Remaining Outstanding Amount of $11.7 million accounts payable-affiliates balance and the Partnership was released from such obligation.
	Revenues and cost of revenues
	Prior to the IPO on July 31, 2013, the Partnership provided processing services for a subsidiary of SEV, whereby the Partnership gathered natural gas from third parties, extracted NGLs, and redelivered the processed natural gas to the subsidiary of SEV. Under certain third-party contracts, the Partnership transfered all natural gas purchased to the subsidiary of SEV at market price. The Partnership also replaced energy used in processing due to the extraction of liquids, compression and transportation of natural gas, and fuel by purchasing natural gas from a subsidiary of SEV at the same market price. The Partnership used the MMBtu volume to measure how much energy is used in processing. Cost of natural gas, NGLs and condensate revenue—affiliates included in the Partnership’s results of operations for the three and nine months ended September 30, 2013 and 2012 from these agreements were $0.1 million and $2.3 million and $3.0 million and $5.4 million, respectively.
	Additionally, the Partnership has entered into a gas transportation agreement with a subsidiary of SEV. The Partnership receives the higher of (i) a minimum monthly payment or (ii) a transportation fee per MMBtu times actual volumes delivered. The current transportation agreement was set to expire on February 28, 2013, but was extended for three additional years at a fixed rate per MMBtu without a minimum monthly payment. Included in the Partnership’s results of operations for the three and nine months ended September 30, 2013 and 2012 are gathering, processing and other revenue—affiliates of less than $0.1 million and $0.1 million and approximately $0.1 million and $0.2 million, respectively, related to these transactions.
	In connection with the IPO, the Partnership entered into a three-year fee-based commercial agreement with a subsidiary of SEV, requiring a minimum monthly volume commitment of 80 MMcf/d. This agreement became effective August 1, 2013. Included in the Partnership's results of operations for the three and nine months ended September 30, 2013 are gathering, processing, transloading and other revenue—affiliates of $2.3 million and $2.3 million, respectively, related to this agreement. Cost of natural gas, NGLs and condensate revenue - affiliates included in the Partnership’s results of operations for the three and nine months ended September 30, 2013 related to this agreement were $1.3 million and $1.3 million, respectively.
	In connection with the IPO, the Partnership entered into three-year transloading services agreements with a subsidiary of SEV, requiring minimum monthly volume commitments for crude oil transloading services. Included in the Partnership's results of operations for the three and nine months ended September 30, 2013 are gathering, processing, transloading and other revenue—affiliates of $2.3 million and $2.3 million, respectively, related to these agreements.
	Cost allocations
	Prior to the IPO, SEV and its affiliates had paid certain expenses on behalf of the Partnership, such as insurance, professional fees, and financing fees. These expenses were reimbursed by the Partnership to SEV and its affiliates and are included in operation and maintenance—affiliates and general and administrative—affiliates in the condensed consolidated and combined Statements of Operations. In addition, SEV and its affiliates have allocated certain overhead costs associated with general and administrative services, including facilities, information services, human resources and other support departments to the Partnership. Where costs incurred on the Partnership’s behalf could not be determined by specific identification, the costs were primarily allocated to the Partnership based on percentage of departmental usage, wages or headcount. The Partnership believes these allocations were a reasonable reflection of the utilization of services provided. However, the allocations may not fully reflect the expenses that would have been incurred had the Partnership been a stand-alone company during the periods presented.
	At the closing of the IPO, the Partnership entered into an omnibus agreement with NuDevco and its affiliates which addresses the management and administrative and overhead services to be provided by NuDevco to the Partnership and the corresponding fees and expense reimbursements to be paid to NuDevco in connection therewith. Under the omnibus agreement, the Partnership pays an annual fee, initially in the amount of $0.6 million, for executive management services.
	The total amount charged to the Partnership for direct reimbursement of operating and overhead cost allocations, which is recorded in operation and maintenance—affiliates, for the three months ended September 30, 2013 and 2012 was $1.3 million and $0.2 million, respectively, and for the nine months ended September 30, 2013 and 2012 was $1.8 million and $0.5 million, respectively. The total amount charged to the Partnership for direct reimbursement of administrative and overhead cost allocations, which is recorded in general and administrative—affiliates, for the three months ended September 30, 2013 and 2012 was $1.6 million and $0.2 million, respectively, and for the nine months ended September 30, 2013 and 2012, was $2.3 million and $0.8 million, respectively.
	Equipment purchase
	In 2012, the Partnership purchased a field office facility, vehicles and computer equipment from an affiliate of SEV for $0.3 million. The purchased assets were bought by the Partnership at SEV’s historical cost basis at the time of sale, as the transactions were between entities under common control.
	Capital Contributions
	During the seven months prior to the IPO on July 31, 2013, the Partnership received capital contributions of $3.6 million from its sole member, who is also the sole member of SEV and NuDevco.

EQUITY BASED COMPENSATION	EQUITY BASED COMPENSATION
	In connection with the IPO, the board of directors of the Partnership’s general partner adopted the Marlin Midstream Partners, LP 2013 Long-Term Incentive Plan (LTIP). Individuals who are eligible to receive awards under the LTIP including (1) employees of the Partnership and NuDevco Midstream Development and its affiliates, (2) directors of the Partnership’s general partner, and (3) consultants. The LTIP provides for the grant of unit options, unit appreciation awards, restricted units, phantom units, distribution equivalent rights, unit awards, profits interest units, and other unit-based awards. The maximum number of common units issuable under the LTIP is 1,750,000.
	On August 1, 2013, phantom units, with distribution equivalent rights, of 292,000 units were awarded to certain employees of NuDevco Midstream Development and its affiliates who provide direct or indirect services to the Partnership pursuant to affiliate agreements and 20,000 units were awarded to certain board members of the Partnership’s general partner. All of the phantom unit awards granted to-date are considered non-employee equity based awards and are required to be remeasured at fair market value at each reporting period and amortized to compensation expense on a straight-line basis over the vesting period of the phantom units with a corresponding increase in partners’ capital as management intends to settle the awards by issuing common units upon vesting and the phantom unit awards were awarded to individuals who are not deemed to be employees of the Partnership. Distribution equivalent rights are accrued for each phantom unit award as the Partnership declares cash distributions and is recorded a decrease in partners’ capital with a corresponding liability in accordance with the vesting period of the underlying phantom unit, which will be settled in cash when the underlying phantom units vest. As of September 30, 2013 no liability has been recorded as the Partnership had not declared any distribution.
	The phantom units awarded to employees of NuDevco Midstream Development and its affiliates will vest in five equal annual installments with the first installment vesting on June 30, 2014, provided that for any individual who has attained a total of five or more years of service with NuDevco Midstream Development or its affiliates at the grant date of award the phantom unit awards will fully vest on February 15, 2014. The phantom unit awards to board members of the Partnership’s general partner will fully vest on February 15, 2014.
	For the three and nine month periods ended September 30, 2013, approximately $0.9 million in compensation expense was recorded in general and administrative expenses - affiliates and approximately $0.4 million in compensation expense was recorded in operation and maintenance - affiliates in the condensed consolidated and combined Statements of Operations. No compensation expense was recorded for the same periods in 2012 as there were no LTIP awards outstanding. A summary of the phantom units activity during the nine months ended September 30, 2013 is presented below:
		Number of shares	Weighted Average Grant-Date Fair Value
	Total Non-vested at January 1, 2013	—	$	—
	Granted	312,000	20
	Exercised	—	—
	Forfeited or canceled	—	—
	Total Outstanding at September 30, 2013	312,000	$	20
	Unrecognized compensation expense associated with the unvested phantom units at September 30, 2013 was approximately $4.3 million and is expected to be recognized over a weighted average period of five years.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	In preparing financial statements in accordance with GAAP, management makes informed judgments and estimates that affect the reported amounts of assets, liabilities, revenues, and expenses. Management evaluates its estimates and related assumptions regularly, utilizing historical experience and other methods considered reasonable under the particular circumstances. Changes in facts and circumstances or additional information may result in revised estimates and actual results may differ from these estimates. Effects on the business, financial condition and results of operations resulting from revisions to estimates are recognized when the facts that give rise to the revision become known.
Consolidation	The condensed consolidated and combined financial statements include the accounts of the Partnership and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.
	Certain information and note disclosures commonly included in annual financial statements have been condensed or omitted pursuant to the rules and regulations of the SEC. Accordingly, the accompanying condensed consolidated and combined financial statements and notes should be read in conjunction with the Partnership’s prospectus relating to the IPO, as filed with the SEC on July 29, 2013. Management believes that the disclosures made are adequate to make the information not misleading.
	The accompanying condensed consolidated and combined financial statements have been prepared in accordance with Regulation S-X, Article 3, General Instructions as to Financial Statements and Staff Accounting Bulletin ("SAB") Topic 1-B, Allocations of Expenses and Related Disclosures in Financial Statements of Subsidiaries, Divisions or Lesser Business Components of Another Entity. Certain expenses incurred by SEV are only indirectly attributable to its ownership of Marlin Midstream prior to the IPO. As a result, certain assumptions and estimates are made in order to allocate a reasonable share of such expenses to the Partnership, so that the accompanying condensed consolidated and combined financial statements reflect substantially all costs of doing business. The allocations and related estimates and assumptions are described more fully in Note 11 ("Transactions with Affiliates"), which the Partnership believes are reasonable.
	SEV has allocated various corporate overhead expenses to the Partnership based on percentage of departmental usage, wages or headcount. These allocations are not necessarily indicative of the cost that the Partnership would have incurred had it operated as an independent stand-alone entity. As such, the condensed consolidated and combined financial statements do not fully reflect what the Partnership's financial position, results of operations and cash flows would have been had the Partnership operated as a stand-alone company during the periods presented.
	At the closing of the IPO, the Partnership entered into an omnibus agreement with NuDevco and its affiliates which addresses the management and administrative services to be provided by NuDevco to the Partnership and the corresponding fees and expense reimbursements to be paid to NuDevco in connection therewith. Under the omnibus agreement, the Partnership pays an annual fee, initially in the amount of $0.6 million, for executive management services and is allocated general and administrative and operating expenses that are directly attributable to the Partnership.
	Marlin Midstream has also historically relied upon SEV and its affiliates as a participant in SEV's credit facility. As a result, historical combined financial information is not necessarily indicative of what the Partnership's results of operations, financial position and cash flows will be in the future.
Subsequent Events	Subsequent Events
	Subsequent events have been evaluated through the date these financial statements are issued. Any material subsequent events that occurred prior to such date have been properly recognized or disclosed in the condensed consolidated and combined financial statements.
Segment Reporting	The Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 280, Segment Reporting, established standards for entities to report information about the operating segments and geographic areas in which they operate. The Partnership operates two segments: the gathering and processing segment and the crude oil logistics segment. All of the Partnership's operations are located in the United States.
Net Income Per Unit	The Partnership has omitted net income per unit for all historical periods prior to the IPO because the Partnership operated under a sole member equity structure for the prior years presented, which is different than the capital structure resulting from the consummation of the IPO and, as a result, the per unit data for periods prior to the IPO would not be meaningful to investors
Recent Accounting Pronouncements	In December 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-11, Disclosures about Offsetting Assets and Liabilities ("ASU 2011-11"). ASU 2011-11 retains the existing offsetting requirements and enhances the disclosure requirements to allow investors to better compare financial statements prepared under GAAP with those prepared under International Financial Reporting Standards ("IRFS"). On January 31, 2013, the FASB issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities ("ASU 2013-01"). ASU 2013-01 limits the scope of the new balance sheet offsetting disclosure to derivatives, repurchase agreements and securities lending transactions. Both standards are effective for interim and annual periods beginning January 1, 2013 and should be applied retrospectively. The Partnership adopted both standards on January 1, 2013. The standards did not have an effect on the Partnership's condensed financial statement footnotes, as the Partnership's derivative financial instruments are not presented on a net basis in the Partnership' s condensed consolidated and combined Balance Sheets.
	In February 2013, the FASB issued ASU No. 2013-02, Reporting Amounts Reclassified Out of Accumulated Comprehensive Income ("ASU 2013-02"), related to the reporting of amounts reclassified out of accumulated other comprehensive income.This guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the related notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period .For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The guidance is effective for annual reporting periods, and interim period s within those years, beginning after December 15, 2012. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. As such, the Partnership can delay the adoption of certain accounting standards until these standards would otherwise apply to private companies. The Partnership has elected to delay such adoption of new or revised accounting standards, and as a result, the Partnership will not adopt ASU 2013-02 until interim periods in 2014 as required by nonpublic entities.
