Workover and Completion: well intervention

This 5-day course emphasizes the role of engineers and field operators in planning and executing the Intervention Operations to maintain and increase field production and thus add to the profitability and recoverable reserves. It also emphasizes the significance of the team concept as a factor in optimizing operations success. The course is highlighted with open discussions and problem solving shared by the instructor and participants.

By the end of this course, attendees will have an understanding of the industry’s advanced technologies in field of designing and executing Intervention jobs in their respective operations. They will have knowledge of selecting the appropriate method for the particular operation and perform the task in a safe and efficient manner.

To provide an in-depth knowledge of the theoretical and practical aspects of Well Intervention operations. At the end of the course delegates will learn about the many processes involved Well Intervention operations, about Well Intervention equipment, how to plan a Well Intervention, and how to execute a Well Intervention operation.

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
