Course Overview
This comprehensive 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 practical insights into best practices, risk management, and operational efficiency to ensure safe and successful workover campaigns.
