On December 8, 2016, USA Compression Partners, LP (the “Partnership”) and USA Compression GP, LLC (the “General Partner,” and together with the Partnership, the “Partnership Parties”) entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, UBS Securities LLC and Wells Fargo Securities, LLC, for themselves and as representatives of the other underwriters named therein (the “Underwriters”), providing for the offer and sale (the “Offering”) by the Partnership of 4,500,000 common units representing limited partner interests in the Partnership (“Common Units”), at a price to the public of $16.25 per Common Unit ($15.6812 per Common Unit, net of underwriting discounts and commissions). Pursuant to the Underwriting Agreement, the Partnership also granted the Underwriters an option for a period of 30 days to purchase up to an additional 675,000 Common Units on the same terms. On December 9, 2016, the Underwriters exercised in full their option to purchase an additional 675,000 Common Units. The Offering is expected to close on December 14, 2016.

The material terms of the Offering are described in a prospectus (the “Prospectus”), filed by the Partnership with the Securities and Exchange Commission (the “Commission”), pursuant to Rule 424(b)(5) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is registered with the Commission pursuant to a Registration Statement on Form S-3, as amended (File No. 333-193724), which was declared effective by the Commission on June 4, 2015.

The Underwriting Agreement contains customary representations, warranties and agreements of the Partnership Parties, and customary conditions to closing, obligations of the parties and termination provisions. The Partnership Parties have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Underwriters may be required to make because of any of those liabilities.

The Partnership will receive net proceeds (after deducting underwriting discounts and commissions, but before paying offering expenses payable by the Partnership) from the Offering of approximately $81,150,210. As described in the Prospectus, the Partnership will use the net proceeds of the sale of the Common Units to reduce the indebtedness outstanding under its revolving credit facility and for general partnership purposes.

As described in the Prospectus, affiliates of certain of the Underwriters are lenders under the Partnership’s revolving credit facility and will receive a substantial portion of the proceeds from this offering pursuant to the repayment of a portion of the borrowings thereunder. In addition, certain of the Underwriters have in the past provided and may from time to time in the future provide commercial banking, investment banking and advisory services in the ordinary course of their business for the Partnership Parties and their respective affiliates, as applicable, for which they have received, and in the future will be entitled to receive, customary fees and reimbursement of expenses.

The foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is attached as Exhibit 1.1 to this report and incorporated in this Item 8.01 by reference.

(c)                                        Information in Issuer Free Writing Prospectus.  Each of the Partnership Parties represents and agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus, or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, to give prompt notice thereof to the Representatives and, if requested by the Representatives, to prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Partnership by an Underwriter through the Representatives expressly for use therein.

7.                                      Expenses.  Each of the Partnership Parties covenants and agrees with the several Underwriters that the Partnership will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Partnership’s counsel and accountants in connection with the registration of the Units under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing the Blue Sky Memorandum and closing documents (including any compilations thereof) in connection with the offering, purchase, sale and delivery of the Units; (iii) all expenses in connection with the qualification of the Units for offering and sale under state securities laws as provided in Section 5(b) hereof, including the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) all fees and expenses in connection with listing the Units on the NYSE; (v) the filing fees incident to any required review by the Financial Industry Regulatory Authority, Inc. (“FINRA”) of the terms of the sale of the Units; (vi) the cost of preparing certificates for the Units; (vii) the cost and charges of any transfer agent or registrar; (viii) the transportation and other expenses incurred by or on behalf of Partnership representatives in connection with presentations to prospective purchasers of the Units; and (ix) all other costs and expenses incident to the performance of the obligation of the Partnership hereunder that are not otherwise specifically provided for in this Section 7.  It is understood, however, that, except as provided in this Section 7 and Sections 9 and 12 hereof, the Underwriters will pay all of their own

costs and expenses, including the fees of their counsel, stock transfer taxes on resale of any of the Units by them and any advertising expenses connected with any offers they may make.

8.                                      Conditions of Underwriters’ Obligations.  The obligations of the Underwriters hereunder, as to the Units to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties of the Partnership Parties herein are, at and as of such Time of Delivery, true and correct, the condition that the Partnership Parties shall have performed all of their obligations hereunder theretofore to be performed, and the following additional conditions:

(a)                                       The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 5(a) hereof; all material required to be filed pursuant to Rule 433(d) under the Act shall have been filed with the Commission within the applicable time period prescribed for such filing by Rule 433 under the Act; if the Partnership has elected to rely upon Rule 462(b) under the Act, the Rule 462(b) Registration Statement shall have become effective by 10:00 p.m., Washington, D.C. time, on the date of this Agreement; no stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceeding for that purpose shall have been initiated or threatened by the Commission; no stop order suspending or preventing the use of a Prospectus or any Issuer Free Writing Prospectus shall have been initiated or threatened by the Commission; and all requests for additional information on the part of the Commission shall have been complied with to your reasonable satisfaction;

(b)                                       The Representatives shall have received the opinion of Vinson & Elkins L.L.P., counsel for the Partnership, to the effect set forth on Exhibit B addressed to them and dated such Time of Delivery, in form and substance reasonably satisfactory to the Representatives;

(c)                                        The Representatives shall have received the opinion of J. Gregory Holloway, Vice President, General Counsel and Corporate Secretary of the General Partner, addressed to them and dated such Time of Delivery, in form and substance reasonably satisfactory to the Representatives, to the effect set forth on Exhibit C hereto;

(d)                                       The Representatives shall have received from Latham & Watkins LLP, counsel to the Underwriters, such opinion or opinions, dated such Time of Delivery with respect to such matters as the Representatives may reasonably require; and the Partnership Parties shall have furnished to such counsel such documents as they reasonably request for the purposes of enabling them to review or pass on the matters referred to in this Section 8 and in order to evidence the accuracy, completeness and satisfaction of the representations, warranties and conditions herein contained;

(e)                                        On the date of the Prospectus at the time of the execution of this Agreement, at 8:30 p.m., New York City time, and also at each Time of Delivery, KPMG LLP shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you;

(f)                                         (i) None of the Partnership Entities shall have sustained since the date of the latest audited financial statements included in the Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, other than as set forth or contemplated in the Prospectus, and (ii) since the respective dates as of which information is given in the Prospectus there shall not have been any change in the capitalization or long-term debt of any of the Partnership Entities or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, members’ equity, partners’ equity or results of operations of any of the Partnership Entities other than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus;

(g)                                        On or after the Applicable Time, there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the NYSE; (ii) a suspension or material limitation in trading in the Partnership’s securities on the NYSE; (iii) a general moratorium on commercial banking activities declared by Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Representatives makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered at such Time of Delivery on the terms and in the manner contemplated in the Prospectus;

(h)                                       The Units to be sold at such Time of Delivery shall have been duly admitted for trading and quotation on the NYSE;

(j)                                          The Partnership shall have furnished or caused to be furnished to the Representatives at such Time of Delivery certificates of officers of the Partnership Parties satisfactory to the Representatives as to the accuracy of the representations and warranties of the Partnership Parties herein at and as of such Time of Delivery, as to the performance by the Partnership Parties of all of their obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in Sections 8(a) and 8(f) hereof and any such further information, opinions, certificates and documents as the Representatives may have reasonably requested.

9.                                      Indemnification.

(a)                                       The Partnership Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter, its directors, officers and employees, each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and any “affiliate” (within the meaning of Rule 405 under the Act) of such Underwriter participating in the offering of the Units, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter, affiliate, director, officer, employee, controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto, any “road show” (as defined in Rule 433 under the Act) not constituting an Issuer Free Writing Prospectus (“Marketing Materials”) or “any issuer information” (as defined in Rule 405 under the Act) used or referred to by such Underwriter with the prior consent of the Partnership (any such issuer information with respect to whose use the Partnership has given its consent, the “Permitted Issuer Information”), or arise out of or are based upon the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto, any Marketing Materials or any Permitted Issuer Information, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, and will reimburse each Underwriter and each such affiliate, director, officer, employee or controlling person for any legal or other expenses reasonably incurred by such Underwriter and each such affiliate, director, officer, employee or controlling person in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Partnership Parties shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto, any Marketing Materials or any Permitted Issuer Information, in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through the Representatives expressly for use therein.

(b)                                       Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Partnership Parties, their respective directors, officers and employees and each person, if any, who controls any Partnership Party within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which such Partnership Party, director, officer, employee or controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials, or arise out of or are based upon the omission or alleged omission to state in the Registration Statement, any

Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representatives expressly for use therein; and will reimburse the Partnership Parties for any legal or other expenses reasonably incurred by the Partnership Parties in connection with investigating or defending any such action or claim as such expenses are incurred. The Underwriters severally confirm and the Partnership acknowledges and agrees that the statements set forth on the cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for use in the Registration Statement, any Preliminary Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication and/or any Issuer Free Writing Prospectus.

(c)                                        Promptly after receipt by an indemnified party under Sections 9(a) or 9(b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability it may have to any indemnified party under such Section, except to the extent that the indemnifying party suffers actual prejudice as a result of such failure and shall not relieve the indemnifying party from any liability it may have other than under such Section.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party.  After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such Section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 9 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees or controlling persons shall have reasonably concluded that there may be legal

defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party.  No indemnifying party shall, (x) without the written consent of the indemnified party (which consent shall not be unreasonably withheld), effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the third sentence of this Section 9(c), then the indemnifying party agrees that it shall be liable for any settlement of any such proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle.

(d)                                       If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under this Section 9 in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, from the offering of the Units.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits referred to in the immediately preceding sentence, but also the relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations.  The relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover

page of the Prospectus.  The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  Each of the Partnership Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 9(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this Section 9(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 9(d), each affiliate of an Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director and officer of the Partnership Parties, and each person, if any, who controls the Partnership Parties within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Partnership Parties.  The Underwriters’ obligations in this Section 9(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

10.                               Underwriters.

(a)                                       If any Underwriter shall default in its obligation to purchase the Units which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Units on the terms contained herein.  If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Units, then the Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Units on such terms.  In the event that, within the respective prescribed periods, you notify the Partnership that you have so arranged for the purchase of such Units, or the Partnership notifies you that it has so arranged for the purchase of such Units, you or the Partnership shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Partnership agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary.  The term “Underwriter” as used in this Agreement shall include any person substituted under this

Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Units.

(b)                                       If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in Section 10(a) above, the aggregate number of such Units which remains unpurchased does not exceed one eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the number of Units which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)                                        If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in Section 10(a) above, the aggregate number of such Units which remains unpurchased exceeds one eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, or if the Partnership shall not exercise the right described in Section 10(b) above to require non-defaulting Underwriters to purchase Units of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to an Optional Unit Time of Delivery, the obligations of the Underwriters to purchase and of the Partnership to sell the Optional Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Partnership, except for the expenses to be borne by the Partnership and the Underwriters as provided in Sections 7 and 12 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11.                               The respective indemnities, agreements, representations, warranties and other statements of the Partnership and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any of them, or any officer or director or controlling person of any of them, and shall survive delivery of and payment for the Units.

12.                               If this Agreement shall be terminated pursuant to Section 8(g) or Section 10 hereof, the Partnership shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, any Units are not delivered by or on behalf of the Partnership as provided herein, the Partnership will reimburse the Underwriters through you for all out of pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Units not so delivered, but the Partnership Parties shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13.                               No Fiduciary Duty.  The Partnership acknowledges and agrees that (i) the purchase and sale of the Units pursuant to this Agreement is an arm’s-length commercial

transaction between the Partnership, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Partnership Parties, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Partnership Parties with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Partnership Parties on other matters) or any other obligation to the Partnership Parties except the obligations expressly set forth in this Agreement and (iv) each of the Partnership Parties has consulted its own legal and financial advisors to the extent it deemed appropriate.  Each of the Partnership Parties agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Partnership Parties, in connection with such transaction or the process leading thereto.

14.                               In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly.

All statements, requests, notices and agreements hereunder shall be in writing and, if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of J. P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179 (fax: (212) 622-8358); Attention Equity Syndicate Desk; and if to the Partnership Parties shall be delivered or sent by mail, telex or facsimile transmission to the address of the Partnership set forth in the Registration Statement, Attention: J. Gregory Holloway; provided, however, that notices under Section 9(c) shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Partnership by you upon request; provided, however, that notices under Section 5(f) shall be in writing, and, if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of J. P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179 (fax: (212) 622-8358); Attention Equity Syndicate Desk.  Any such statements, requests, notices or agreements shall take effect upon receipt thereof.  In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

15.                               This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters and the Partnership Parties, and, to the extent provided in Sections 9 and 11 hereof, the officers, directors and affiliates of any Partnership Party and Underwriter, and each person who controls such Partnership Party or Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement.  No purchaser of any of the Units from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

16.                               Time shall be of the essence of this Agreement.  As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

17.                               This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Partnership Parties and the Underwriters, or any of them, with respect to the subject matter hereof.

18.                               THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK.  Each of the parties agrees that any suit or proceeding arising in respect of this agreement or the Underwriters’ engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in the City and County of New York, and each of the parties agrees to submit to the jurisdiction of, and to venue in, such courts.

19.                               Each of the Partnership Parties and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20.                               This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

21.                               Notwithstanding anything herein to the contrary, the Partnership is authorized, subject to applicable law, to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) relating to such treatment and structure, without the Underwriters imposing any limitation of any kind.  However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with applicable securities laws.  For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

22.                               If the foregoing is in accordance with your understanding, please sign and return to the Partnership, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters and each of the Partnership Parties.

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with USA Compression Partners, LP (the “Partnership”), and USA Compression GP, LLC, providing for a public offering of common units representing limited partner interests (the “Common Units”) in the Partnership pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “Commission”).

In consideration of the agreement by the Underwriters to offer and sell the Units (as defined in the Underwriting Agreement), and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not, directly or indirectly, (1) offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise hedge or dispose of (or enter into any transaction or device that is designed to, or could reasonably be expected to, result in the disposition at any time in the future of) any Common Units (as defined in the First Amended and Restated Agreement of Limited Partnership of the Partnership, as the same may be amended or restated at or prior to the Initial Time of Delivery, as defined in the Underwriting Agreement), or any securities of the Partnership that are substantially similar to the Common Units, including, but not limited to, any options or warrants to purchase any Common Units, or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Units or any such substantially similar securities, whether now owned or hereinafter acquired, owned directly by the undersigned (including

Exhibit A - 1

holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Commission (collectively the “Undersigned’s Units”), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of any Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Units or securities convertible into or exercisable or exchangeable for Common Units or any other securities of the Partnership, or (4) publicly disclose the intention to do any of the foregoing.  The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Units even if the Undersigned’s Units would be disposed of by someone other than the undersigned.  Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Units or with respect to any security that includes, relates to, or derives any significant part of its value from the Undersigned’s Units.

The initial Lock-Up Period will commence on the date of this Lock-Up Letter and continue for 45 days after the date of the Prospectus (as defined in the Underwriting Agreement).

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Units (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of J.P. Morgan Securities LLC; provided, however, that in the case of (i) or (ii), any such transfer shall not involve a disposition for value and no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with such transfer other than a filing on Form 5 of the Exchange Act.  For purposes of this Lock-Up Letter, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.  The undersigned also agrees and consents to the entry of stop transfer instructions with the Partnership’s transfer agent and registrar against the transfer of the Undersigned’s Units except in compliance with the foregoing restrictions.

It is understood that, if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, the undersigned shall be automatically released from the obligations under this Lock-up Letter Agreement.

Exhibit A - 2

The undersigned understands that the Partnership and the Underwriters are relying upon this Lock-Up Letter in proceeding toward consummation of the offering.  The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

In connection with this opinion, we have assumed that all Units will be issued and sold in the manner stated in the Prospectus Supplement, the Base Prospectus and the Underwriting Agreement.

Based upon the foregoing and subject to the assumptions, exceptions, limitations and qualifications set forth below, we are of the opinion that, except as described in the Registration Statement, the Prospectus Supplement and the Base Prospectus, when the Units

have been issued and delivered in accordance with the terms of the Underwriting Agreement, then the Units will be validly issued, fully paid and non-assessable.

The opinions expressed herein are qualified in the following respects:

We are expressing no opinion as to the effect of the laws of any other jurisdiction.

We hereby consent to the filing of this opinion of counsel as Exhibit 5.1 to the Current Report on Form 8-K of the Partnership dated on or about the date hereof, to the incorporation by reference of this opinion of counsel into the Registration Statement and to the reference to our Firm under the heading “Validity of the Common Units” and “Legal Matters” in the Prospectus Supplement and the Base Prospectus, respectively.

Ladies and Gentlemen:

We have acted as counsel for USA Compression Partners, LP (the “Partnership”), a Delaware limited partnership, with respect to certain legal matters in connection with the preparation of a Prospectus Supplement dated on or about the date hereof (the “Prospectus Supplement”) and the Prospectus with an effective date of June 4, 2015 (“Prospectus”), each forming part of the Registration Statement on Form S-3 (the “Registration Statement”).  The Registration Statement relates to the registration under the Securities Act of 1933, as amended, (the “Securities Act”) of common units representing limited partner interests in the Partnership.

This opinion is based on various facts and assumptions, and is conditioned upon certain representations made by the Partnership as to factual matters through certificates of officers of the Partnership (the “Officer’s Certificates”). In addition, this opinion is based upon the factual representations of the Partnership concerning its business, properties and governing documents as set forth in the Registration Statement.

In our capacity as counsel to the Partnership, we have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and other instruments, as we have deemed necessary or appropriate for purposes of this opinion. In our examination, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures thereon, the legal capacity of natural persons executing such documents and the conformity to authentic original documents of all documents submitted to us as copies. For the purpose of our opinion, we have not made an independent investigation or audit of the facts set forth in the above-referenced documents or in the Officer’s Certificates. In addition, in rendering this opinion we have assumed the truth and accuracy of all representations and statements made to us which are qualified as to knowledge or belief, without regard to such qualification.

We hereby confirm that all statements of legal conclusions contained in the discussion in the Prospectus under the caption “Material U.S. Federal Income Tax Consequences,” as updated in the Prospectus Supplement under the caption  “Additional Material U.S. Federal Tax Consequences,” constitute the opinion of Vinson & Elkins L.L.P. with respect to the matters set forth therein as of the effective date of the Registration Statement, subject to the assumptions, qualifications, and limitations set forth therein. This opinion is based on various statutory provisions, regulations promulgated thereunder and interpretations thereof by the Internal Revenue Service and the courts having jurisdiction over such matters, all of which are subject to change either prospectively or retroactively. Also, any variation or difference in the facts from those set forth in the representations described

above, including in the Registration Statement and the Officer’s Certificates, may affect the conclusions stated herein.

No opinion is expressed as to any matter not discussed in the Prospectus under the caption “Material U.S. Federal Income Tax Consequences” or in the Prospectus Supplement under the caption “Additional Material U.S. Federal Tax Consequences.”  We are opining herein only as to the U.S. federal income tax matters described above, and we express no opinion with respect to the applicability to, or the effect on, any transaction of other federal laws, foreign laws, the laws of any state or any other jurisdiction or as to any matters of municipal law or the laws of any other local agencies within any state.

This opinion is rendered to you as of the effective date of the Registration Statement, and we undertake no obligation to update this opinion subsequent to the date hereof. This opinion is furnished to you, and is for your use in connection with the transactions set forth in the Registration Statement. This opinion may not be relied upon by you for any other purpose or furnished to, assigned to, quoted to or relied upon by any other person, firm or other entity, for any purpose, without our prior written consent. However, this opinion may be relied upon by you and by persons entitled to rely on it pursuant to applicable provisions of federal securities law, including persons purchasing common units pursuant to the Registration Statement.

We hereby consent to the filing of this opinion of counsel as Exhibit 8.1 to the Current Report on Form 8-K of the Partnership dated on or about the date hereof, to the incorporation by reference of this opinion of counsel into the Registration Statement and to the reference to our firm in the Prospectus Supplement. In giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act.
