Exhibit 10.11

AGREEMENT FOR SERVICES

AS INDEPENDENT CONTRACTOR

This Agreement (the “Agreement”) is entered into as of the date set forth on the signature page below between BJ SERVICES, LLC, a Delaware limited liability company (the “Company”), and ERIC SNELL (“Consultant”).

1. CONSULTANT’S SERVICES. Consultant wishes to provide advice, consultation, assistance and other services to the Company as an independent contractor, and the Company wishes to engage Consultant as an independent contractor. In performing services under this Agreement, Consultant shall comply with all applicable laws, regulations, ordinances, codes and regulations. Consultant agrees that with respect to each project/assignment accepted, he will meet all applicable project deadlines. Consultant will provide services to the Company with a focus on the tasks and responsibilities as set forth on Exhibit A (the “Services”), and as such exhibit and Services may be supplemented upon mutual agreement of the Company and Consultant from time to time.

2. CONSULTANT’S INDEPENDENT CONTRACTOR STATUS. The Company and Consultant mutually intend that this Agreement establish between them an independent contractor relationship. All of the terms and conditions of this Agreement will be interpreted in light of that relationship. There is no intention to create by this Agreement an employer-employee relationship. Consultant will have no authority to bind the Company to any obligation or liability. The Company agrees that it will have no right to control or direct the details, manner or means by which Consultant accomplishes the results of the Services he performs under this Agreement. Consultant will use his own means and methods to perform the Services covered by this Agreement. However, on the projects accepted by Consultant, Consultant agrees to perform services according to the format that may be prescribed by regulations applicable to the project and according to ordinary business customs in the oil and gas/oilfield services industries. Subject to the restrictions in Section 9 of this Agreement, the Company does not have the exclusive right to Consultant’s services. Subject to the restrictions in Section 9 of this Agreement, Consultant may accept assignments from other companies or persons during the time Consultant is performing the Services for the Company, provided that such assignments do not represent a conflict of interest as to Consultant’s duties to the Company and would not create a situation in which it would be likely to breach Consultant’s obligations to protect the Company’s Confidential Information (as defined below), and as long as Consultant informs the Company of any assignments undertaken in the same general business area as that engaged in by the Company.

3. CONSULTANT’S FEE. For satisfactory performance of the Services described in this Agreement, the Company shall pay to Consultant an aggregate fee of $1,000,000.00 (the “Fee”). The Fee shall be paid as follows: (a) $333,333.33 USD shall be paid on the date of execution of this Agreement, (b) $333,333.33 USD shall be paid on or before, in the sole discretion of the Company, July 3, 2017, and (c) $333,333.34 USD shall be paid on or before, in the sole discretion of the Company, December 31, 2017. The foregoing Fee shall include compensation for all labor costs incurred by Consultant in connection with the performance of the Services hereunder and the Company shall not be responsible for the salaries or expense of any secretaries, clerks, or assistants of any type employed by Consultant, and, except as

expressly stated elsewhere in this Agreement, shall not be responsible to Consultant for any additional remuneration whatsoever. Consultant shall not be entitled, based on the Services he performs under this Agreement, to any employee benefits of the types provided by the Company to its employees. Consultant will be responsible for all expenses related to Consultant’s vehicle, mileage, tolls and parking (within a fifty (50) mile radius of Consultant’s principal place of business), home computer, society memberships, weekly activity reports and similar expenses. Consultant will not receive any additional fee, benefits or compensation for the Services except as expressly set forth herein. Consultant will not be paid for sick days, vacation days, or any other days other than those Consultant actually works. As a condition of the Company’s agreement to retain Consultant’s Services, Consultant, on his own behalf and on behalf of his heirs, executors, administrators and assigns, hereby waives, releases, forever renounces, and covenants not to sue concerning any alleged rights he might otherwise have to receive benefits from any benefit plan for Company employees, including but not limited to retirement plans, 401(k) plans, stock purchase or stock option plans, and plans providing any type of insurance benefit. Consultant understands that the Company is relying on this paragraph in agreeing to pay Consultant the rate set forth in this Agreement.

4. REIMBURSEMENT OF CONSULTANT’S EXPENSES. Unless otherwise set forth herein, the Company will reimburse Consultant for reasonable and necessary expenses directly incurred by Consultant in performing the Services in accordance with this Agreement, such as transportation, lodging, meals, entertainment, telephone, trade show participation costs, and postage. All such expenses shall be substantiated and submitted in accordance with the policies and regulations established from time to time by the Company (“Company Policies”). Consultant shall look to the Company for all requests and approvals required or permitted by this Agreement. The Company will also reimburse expenses as approved in its sole discretion.

5. NO WITHHOLDING OF TAXES. Because Consultant is an independent contractor, the Company shall not withhold taxes of any sort from the consulting fees, and Consultant shall be responsible for payment of all FICA or Medicare taxes due on the consulting fees. Consultant hereby indemnifies the Company for any taxes, penalties, interest, and any accounting or attorneys’ fees incurred by the Company due to Consultant’s failure to pay taxes (including 100% of FICA and Medicare taxes) due on the consulting fees. The Company shall furnish Consultant, on a timely basis, with an IRS form 1099.

6. TERMINATION. The term of this Agreement shall begin on the date hereof and shall expire on December 31, 2017. Notwithstanding the foregoing, the Company may terminate this Agreement at any time, without cause; provided that, in the event of such termination without cause, the Company must pay Consultant the remainder of the unpaid Fee. In the event of a breach of this Agreement by Consultant, the Company shall also have the discretion to terminate this Agreement immediately. In the event that the Company terminates this Agreement for breach, the Company shall, within thirty (30) days after the conclusion of the term of this Agreement, pay to Consultant all fees and expenses owed by the Company as of the date that the Company provided Consultant written notice of termination.

7. PROTECTION OF COMPANY’S CONFIDENTIAL INFORMATION. Consultant acknowledges that it shall have access to the Company’s trade secrets and other nonpublic information belonging to the Company, its affiliated companies, partners, joint

ventures, or clients in connection with the performance of this Agreement, including, without limitation, trade secrets, know-how, business plans, information and knowledge pertaining to products, services, inventions, discoveries, improvements, innovations, designs, ideas, manufacturing, advertising, marketing, vendors, distribution and sales methods, sales and profit figures, pricing, cost structure, customer and client lists and relationships between the Company and dealers, distributors, sales representatives, customers, clients, suppliers and others who have business dealings with them (collectively, “Confidential Information”). Consultant shall at all times maintain such Confidential Information in strict confidence and shall not divulge it to third parties and shall not use it for purposes outside the scope of this Agreement without the prior written consent of the Company. Under no circumstances will Consultant convert Confidential Information for personal use, gain, or benefit or to the personal use, gain or benefit of any third party unless the Company has expressly authorized Consultant in writing to do so. This paragraph shall not apply to Confidential Information if: (a) the information was in Consultant’s possession, as shown by written records, prior to the time that the Company disclosed it to Consultant and was not obtained directly or indirectly from the Company, (b) the information is or later becomes a part of the public domain through no act or omission on the part of Consultant, or (c) the information is obtained by Consultant from a third party who did not receive the same, directly or indirectly, from the Company. Consultant further agrees that Consultant will not, without the prior written consent of the Company, disclose to any third party or use for purposes outside of the scope of this Agreement any information conceived, developed or prepared by Consultant in the performance of this Agreement, except to the extent that said information falls within one of the categories described in (b) or (c) above. At any time that the Company requests Consultant to do so, Consultant shall immediately return to the Company all documents containing Confidential. Information and shall not retain any copies of same, either in hard copy, in electronic form, or in any other form. Consultant’s obligations under this paragraph shall supersede and replace Consultant’s obligations under any nondisclosure or confidentiality agreement previously executed by the parties hereto and shall survive the termination or expiration of this Agreement.

8. COMPANY’S RIGHT TO CONSULTANT’S WORK PRODUCT PREPARED UNDER THIS AGREEMENT. All materials prepared or developed by Consultant in rendering the Services under this Agreement, including documents, notes and reports, shall become the property of the Company when prepared, whether delivered to the Company or not, and shall, together with any materials furnished to Consultant by the Company under this Agreement and all copies thereof, be delivered to the Company upon request and, in any event, upon termination of this Agreement. Consultant hereby assigns to the Company all right, title and interest in and to any and all developments, improvements and inventions conceived or first reduced to practice by Consultant during the period of performance of this Agreement and for a period of six (6) months following the conclusion of the term, to the extent that such developments, improvements or inventions are based upon the technology or business of the Company, its affiliated companies, customers or licensors. Consultant shall promptly disclose such developments, improvements and inventions to the Company and execute all documents and perform all other activities reasonably requested by the Company to file, prosecute, maintain and defend patents on and otherwise protect the proprietary character of such developments, improvements and inventions throughout the world as the Company directs. Notwithstanding the foregoing, any materials prepared or developed by Consultant prior to the term of this Agreement shall remain property of Consultant and shall not, unless otherwise agreed in writing by Consultant, become property of the Company as a result of the Services provided under this Agreement.
