CO2 Corrosion and Erosion Modelling and Rate Prediction

This 3-day course provides a comprehensive overview of CO2 corrosion and erosion mechanisms, modeling, and mitigation strategies for the oil and gas industry. Participants will gain an in-depth understanding of CO2 and CO2/H2S corrosion and their impact on materials selection and asset integrity. The course covers bottom-of-line, top-of-line, and localized corrosion and examines industry best practices for predicting and managing CO2 corrosion rates. Practical case studies are used throughout to reinforce key learnings. The course also introduces various erosion mechanisms and principles for erosion rate modeling and control. Participants will learn to apply corrosion and erosion rate models to make informed decisions that optimize asset life cycle costs. Both onshore and offshore operations will be addressed.

Who Should Attend:

This course provides value to corrosion engineers, materials engineers, and integrity engineers from both design and EPCI companies who are involved in materials selection for oil and gas assets. It is also beneficial for operators who are responsible for verifying design premises and utilizing corrosion rate models as part of overall corrosion and asset integrity management where the models can be used for determination of remaining life predictions and definition of risk-based inspection workscopes.
