By the end of the training, attendees will be equipped to contribute to safer, more reliable, and cost-effective oil and gas operations.

Introduction

Corrosion is a major threat to the integrity and longevity of oil and gas infrastructure, leading to costly repairs, production losses, and potential environmental hazards. Cathodic Protection (CP) is a widely used method for mitigating corrosion by turning a metallic surface into the cathode of an electrochemical cell. This course aims to equip professionals in the oil and gas exploration industry with the knowledge and skills necessary to design, implement, monitor, and maintain effective CP systems. The training covers the fundamental principles of corrosion and CP, various CP techniques, relevant industry standards, and best practices. Participants will gain a deep understanding of how CP systems work, how to select the appropriate CP method for a given application, and how to troubleshoot common CP problems. Through a combination of theoretical instruction, practical exercises, and real-world case studies, this course ensures that participants can immediately apply their new knowledge to their daily work.
