Ladies and Gentlemen:

This opinion is provided in connection with the Registration Statement on Form S-4 (the “Registration Statement”) filed on the date hereof with the Securities and Exchange Commission (the “Commission”) by Pioneer Energy Services Corporation, a Texas corporation (the “Company”), Pioneer Drilling Services, Ltd., a Texas corporation (“Pioneer Drilling”), Pioneer Production Services, Inc., a Delaware corporation (“Pioneer Production”), Pioneer Well Services, LLC, a Delaware limited liability company (“Pioneer Well”), Pioneer Wireline Services Holdings, Inc., a Delaware corporation (“Wireline Holdings”), Pioneer Wireline Services, LLC, a Delaware limited liability company (“Wireline Services”), Pioneer Fishing & Rental Services, LLC, a Delaware limited liability company (“Pioneer Fishing” and together with Pioneer Drilling, Pioneer Production, Pioneer Well, Wireline Holdings, Wireline Services and Pioneer Fishing, the “Delaware/Texas Guarantors”) and Pioneer Coiled Tubing Services, LLC, a Louisiana limited liability company (“Pioneer Coiled Tubing” and, together with the Delaware/Texas Guarantors the “Subsidiary Guarantors”), under the Securities Act of 1933, as amended (the “Act”), relating to the registration under the Act of the offering and issuance of $300,000,000 aggregate principal amount of the Company’s 6.125% Senior Notes due 2022 (the “Exchange Notes”), together with the guarantees of the Subsidiary Guarantors of the Exchange Notes, in exchange for a like principal amount of the Company’s issued and outstanding 6.125% Senior Notes due 2022, issued March 18, 2014 (the “Outstanding Notes”) and the guarantees of the Subsidiary Guarantors of

the Outstanding Notes. The Exchange Notes and the guarantees are to be issued under an Indenture, dated as of March 18, 2014 (the “Indenture”), by and among the Company, the Subsidiary Guarantors, and Wells Fargo Bank, National Association, as trustee (the “Trustee”). At your request, this opinion is being furnished to you for filing as Exhibit 5.2 to the Registration Statement.

We are acting as special counsel solely for Pioneer Coiled Tubing in the State of Louisiana and not for the other parties to the aforedescribed transaction.

All documents executed or to be executed in connection with the filing of the Registration Statement and the issuance of the Exchange Notes together with all other documents executed March 18^th in connection with the issuance of the Rule 144A Global Note (which we did not review) are referred to as the “Transaction Documents”).

We have reviewed copies of the Indenture and the exhibits attached thereto, the Amended and Restated Operating Agreement of Go Coil, LLC dated January 31, 2012 (the “Operating Agreement”) (Go Coil’s name was subsequently changed to Pioneer Coiled Tubing Services, LLC but the Operating Agreement has not yet been amended to reflect same) as ratified by a Ratification of the Operating Agreement dated March 17, 2014, and of the Articles of Organization of Pioneer Coiled Tubing (including the amendment changing the name of the company from Go Coil, LLC to Pioneer Coiled Tubing Services, LLC dated July 9, 2012, filed and effective August 1, 2012) and resolutions and/or manager or officer certificates of Pioneer Coiled Tubing dated January 21, 2012, July 9, 2012, January 21, 2012, March 3, 2014, March 18, 2014, August 28, 2014 and September 26, 2014, presented to us by Pioneer Coiled Tubing (collectively, the “Pioneer Entity Records”). In rendering the opinions expressed herein, we have relied, without independent investigation or verification, with respect to matters of fact upon certificates of officers of the Company and upon the Pioneer Entity Records. We have not reviewed any documents other than the Pioneer Entity Records. We have not reviewed the Form S-4 Registration Statement to be executed by the Company. We have not interviewed officials of any party to the Transaction Documents or examined the records of any courts in any state with respect to any party to the Transaction Documents. We assume that the performance of any obligations referred to in the documents which are incorporated by reference into the Transaction Documents (and which are not also Transaction Documents) will not violate Louisiana law or the organizational documents of Pioneer Coiled Tubing.

ASSUMPTIONS

In rendering the opinions set forth below, we have assumed without any independent investigation or verification:

A. All signatures on the Transaction Documents and the Pioneer Entity Records and any other document presented to us by any party to this transaction or their counsel are genuine.

B. All natural persons, including all persons acting on behalf of a firm or other business entity, are legally competent, and have not been fraudulently induced to become a party to the Transaction Documents or the Pioneer Entity Records and had the legal capacity to execute such documents at the time of execution thereof.

C. All documents submitted to us as originals are authentic. All documents submitted to us as copies conform to the original document. All public records reviewed are accurate and complete.

There are no other Members of Pioneer Coiled Tubing other than as set forth in the Operating Agreement. All authorizing resolutions, consents and certificates presented to us have not been and will not be revoked on or prior to the consummation of the transactions such documents authorize.

Upon your receipt of this letter, you will have automatically and unconditionally accepted and agreed to all of the assumptions, limitations, qualifications, and exceptions set forth in this letter, without any affirmative action on your part, and said acceptance may not be terminated, qualified, limited, made conditional, amended, altered, or modified in any manner or in any respect.

We hereby consent to the reference to this firm under the caption “Legal Matters” in the prospectus forming a part of the Registration Statement, and to the filing of this opinion as an exhibit to the Registration Statement.
