Downhole Remediation Practices
for Mature Oil and Gas Wells

Downhole remediation practices for mature oil and gas wells is a technically demanding discipline requiring a structured approach to diagnosis, treatment, and long-term performance recovery.

This course covers the full remediation lifecycle from identifying the causes of wellbore damage through to designing, executing, and evaluating remediation programs.

Delegates work through chemical treatments for scale, corrosion, and organic deposits, mechanical remediation methods, and the safety protocols governing program execution.

Real-world case studies and hands-on exercises run across all five days, including a final practical session in remediation program design and execution.

The course also addresses post-remediation monitoring and long-term strategy optimisation giving delegates the tools to sustain well performance beyond the immediate intervention.

This downhole remediation practices for mature oil and gas wells course is designed to build delegate capability across every stage of the remediation process from initial diagnostics through to post-intervention performance evaluation.

By the end of this course, delegates will be able to:

• Identify causes of wellbore damage — Analyse the effects of damage mechanisms common in mature wells and select appropriate remediation strategies.
• Apply chemical treatment methods — Use chemical treatments to address scale, corrosion, and organic deposits effectively.
• Execute mechanical remediation techniques — Select and apply mechanical methods suited to specific downhole conditions.
• Design remediation programs — Build programs using wellbore data, success metrics, and structured planning frameworks.
• Implement programs safely — Apply safety best practices and monitoring protocols during live remediation execution.
• Evaluate post-remediation performance — Monitor well performance after intervention and optimise strategies for long-term success.

This downhole remediation practices for mature oil and gas wells course is designed for professionals working directly with mature well assets who need structured technical training across diagnosis, treatment, and program management.

This course is suitable for:

• Petroleum Engineers — Those responsible for maintaining and restoring production performance in mature well environments.
• Well Intervention Specialists — Professionals planning and executing downhole remediation and workover operations.
• Production Engineers — Those monitoring well performance and identifying when remediation intervention is required.
• Reservoir Engineers — Specialists integrating wellbore diagnostics and remediation outcomes into broader reservoir management strategies.
• Drilling Engineers — Engineers involved in wellbore integrity and damage assessment across mature assets.
• HSE Professionals — Personnel with oversight of safety protocols and best practices during remediation program execution.

This downhole remediation practices for mature oil and gas wells course is delivered through a structured combination of technical instruction, case study analysis, and hands-on practical exercises ensuring delegates can apply remediation methods with confidence in real operational settings.

Delivery methods include:

• Instructor-Led Sessions — Expert instruction covers wellbore damage mechanisms, chemical and mechanical remediation techniques, and program design frameworks.
• Case Study Analysis — Real-world remediation examples are examined to develop practical judgement across a range of downhole conditions and treatment scenarios.
• Hands-On Program Design Exercises — Delegates complete structured exercises in remediation program design across Days 3 and 5, working through planning decisions directly.
• Program Execution Practice — A practical execution exercise on Day 4 puts safety protocols and monitoring procedures into applied context.
• Post-Remediation Evaluation Sessions — Day 5 focuses on performance monitoring and long-term strategy optimisation following intervention.

• AZTech Certificate of Completion for delegates who attend and complete the training course
