 Exhibit 4.1 
 SUPPLEMENTAL INDENTURE 
 SUPPLEMENTAL INDENTURE (this “Supplemental
Indenture”), dated as of May 7, 2012, by and among CES Mid-Continent Hamm, LLC, a Delaware limited liability company, CES Rockies, Inc., a Delaware corporation, Complete Energy, LLC, a Delaware limited liability company, Stride Well
Service Company, Inc., a Delaware corporation, and Turner Energy Services, LLC, a Delaware limited liability company (the “Guaranteeing Subsidiaries”), all of which are subsidiaries of SESI, L.L.C., a Delaware limited liability
company (the “Company”), the Company, Superior Energy Services, Inc., a Delaware corporation, the other Guarantors (as defined in the Indenture referred to herein) and The Bank of New York Mellon Trust Company, N.A., as trustee
under the Indenture referred to below (the “Trustee”). 
 W I T N E S S E T H 

WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of
May 22, 2006 providing for the issuance of 6.875% Senior Notes due 2014 (the “Notes”); 
 WHEREAS, the
Indenture provides that under certain circumstances the Guaranteeing Subsidiaries shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiaries shall unconditionally guarantee all of the
Company’s Obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and 
 WHEREAS, pursuant to Sections 4.18 and 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby
acknowledged, the Guaranteeing Subsidiaries and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. Each Guaranteeing Subsidiary hereby agrees, jointly and severally, to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note
Guarantee and in the Indenture, including, but not limited to, Article 10 thereof. 
 3. NO RECOURSE AGAINST OTHERS. No past,
present or future director, officer, organizer, employee, manager, incorporator, stockholder, member or agent of each Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under
the Notes, any Note Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such 

  
 1 

 
obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 
 4. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO
THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
 5. COUNTERPARTS. The parties
may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. 
 6. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof. 
 7. THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained
herein, all of which recitals are made solely by the Guaranteeing Subsidiaries and the Company.
