COURSE OVERVIEW:

This course provides a comprehensive understanding of corrosion mechanisms affecting downhole tubing, completion strings, and associated subsurface equipment in oil and gas wells. Participants will study corrosion drivers such as CO₂, H₂S, oxygen ingress, microbiologically influenced corrosion (MIC), galvanic interactions, erosion–corrosion, and stress-related degradation mechanisms. The course examines how completion design, wellbore fluids, temperature, pressure, salinity, and flow regimes contribute to metal loss and tubing failure.

Detailed focus is given to corrosion monitoring systems, failure analysis, material selection, chemical inhibition, coatings, and mitigation strategies that help optimise well integrity and extend equipment lifecycle. Case studies illustrate real-world downhole corrosion failures, diagnostic techniques, and best practices in managing high-risk wells across various reservoir environments. By the end of the course, participants will have a clear understanding of how to evaluate corrosion risk, implement effective prevention measures, and support safe and economical well operations.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Explain the fundamentals of corrosion and its impact on downhole tubing integrity.
• Identify corrosion mechanisms commonly encountered in oil and gas wells.
• Evaluate environmental and operational factors that accelerate corrosion.
• Distinguish between CO₂, H₂S, oxygen-related, and MIC corrosion.
• Understand galvanic, pitting, localised, and uniform corrosion processes.
• Interpret corrosion failure modes in tubing and completion components.
• Assess material selection criteria, including carbon steel and corrosion-resistant alloys (CRAs).
• Implement corrosion monitoring techniques such as coupons, ER probes, and downhole sensors.
• Evaluate chemical inhibition strategies and select appropriate corrosion inhibitors.
• Understand protective coatings, linings, and tubing design considerations.
• Apply corrosion modelling techniques to predict tubing life and risk severity.
• Develop corrosion mitigation and control plans for specific well conditions.
• Perform basic failure analysis workflows to determine root causes.
• Review industry case studies to apply lessons learned to operational environments.

TARGET AUDIENCE:

• Completion Engineers
• Production Engineers
• Well Integrity Engineers
• Corrosion and Materials Engineers
• Field Operators and Supervisors
• Asset Integrity and Operations Personnel
• Laboratory and Inspection Specialists

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
