Advanced Workover Operations

About the Course

As fields mature and well conditions become more unpredictable, intervention activities grow in complexity and demand greater technical precision. Executing successful workovers now requires a well-coordinated combination of engineering judgment, field experience, and adherence to safety protocols. Common challenges such as mechanical failures, declining flow rates, or sand production often call for targeted interventions to restore well performance. In many cases, optimising completions or adjusting artificial lift systems becomes necessary to maximise output. Workover operations must be carefully designed and executed with increasing pressure to reduce costs, minimise environmental impact, and avoid production interruptions. As a result, advanced workover planning has become a strategic priority for upstream teams seeking to safeguard asset integrity and sustain long-term field performance.

This 5-day comprehensive Advanced Workover Operations training course is designed to give delegates an in-depth understanding of advanced workover operations from planning through post-job evaluation. It emphasizes practical, field-proven techniques that support decision-making across a wide range of well conditions and intervention scenarios. Delegates will strengthen their ability to assess candidate wells, coordinate intervention tools, manage surface and subsurface risk, and align operational objectives with technical solutions that bridge disciplines such as well services, completions, and production operations—giving them the knowledge to lead workover campaigns with greater confidence, safety, and efficiency. It delivers a structured framework for improving performance and minimising downtime in active well environments.

Core Objectives

The delegates will achieve the following objectives:

• Define the operational significance of workovers in extending well life and improving production output
• Distinguish between key criteria used to select wells for intervention based on technical and economic factors
• Classify tools, equipment, and methods commonly applied in advanced workover operations
• Interpret well performance data to support the design of appropriate workover strategies
• Evaluate the effectiveness of selected intervention techniques in resolving downhole complications
• Demonstrate best practices in managing well control, safety protocols, and operational barriers
• Formulate recommendations based on post-job evaluations to optimise future workover planning and execution

Training Approach

This training course follows an instructor-led format combining technical presentations, interactive discussions, and structured problem-solving exercises. Delegates will engage in scenario-based learning to reinforce decision-making across complex workover operations. Designed for practical application, the sessions assist them in connecting engineering concepts with real-world field execution and safety-critical practices.
