Course Overview
This comprehensive 5-day training program is designed to equip Workover Supervisors and related professionals with the essential knowledge and skills required for effective planning, execution, and supervision of workover operations. The course covers key aspects of well intervention, including wellbore diagnostics, rig selection, well control, completion reconfigurations, and post-workover evaluations. Participants will gain hands-on insights into best practices, risk management, and operational efficiency to ensure safe and successful workover campaigns.
Course Objectives
By the end of this course, participants will be able to:
- Understand the fundamentals of workover operations and their significance in well integrity and production enhancement.
- Develop a structured approach to workover planning, including well diagnostics, candidate selection, and job design.
- Identify and mitigate risks associated with workover operations, including well control and HSE considerations.
- Supervise and optimize workover execution, including rig operations, fluid systems, and completion techniques.
- Evaluate post-workover performance and implement lessons learned for continuous improvement.
