COURSE OVERVIEW:

Workover Operations Planning and Execution is a high-level course designed to manage the most complex and expensive phase of well maintenance. Unlike rigless interventions, workovers involve a heavy rig to pull the completion, repair the casing, or sidetrack the well. This program provides the project management and engineering framework required to execute these operations while maintaining strict control over well barriers, costs, and environmental impact.

The scope of this training involves the entire workover workflow, from initial well killing and "bullheading" to the installation of a new completion string. Participants will explore the mechanics of "pulling a well," including the management of stuck packers, tubing retrieval, and casing repair. The curriculum emphasizes the "Decision Gates" involved in workovers, helping engineers decide when a well is worth repairing and when it should be permanently abandoned.

Coverage also focuses on the execution phase at the wellsite. Attendees will learn how to supervise rig crews, manage mud systems during workovers, and ensure the integrity of the primary cement bond during remedial operations. By focusing on the integration of engineering design with rig-site reality, this course enables participants to deliver successful workover projects that restore production, secure the wellbore, and optimize the asset’s recovery factor.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Develop a comprehensive "Workover Program" including risk assessment.
• Calculate kill fluid weights and manage well-kill operations (Bullheading/Circulation).
• Supervise the safe retrieval of the completion string (Tubing and Packers).
• Manage the milling of stuck packers and permanent obstructions.
• Design remedial cementing (squeeze) jobs for zonal isolation repair.
• Identify and repair casing leaks using patches or liners.
• Select and supervise the installation of a new completion BHA.
• Monitor well costs (AFE) and minimize Non-Productive Time (NPT).
• Ensure well control and barrier integrity during all phases of the workover.
• Manage the cleanup and flow-back of the well post-workover.
• Apply Root Cause Analysis (RCA) to premature completion failures.
• Coordinate with third-party service providers for specialized tasks.
• Document the "As-Built" completion for future asset management.

TARGET AUDIENCE:

Workover Engineers, Rig Supervisors, Well Site Leaders, and Production Engineers responsible for well lifecycle management.

TRAINING COURSE METHODOLOGY: 

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
