 Course Overview


CO2 corrosion model validation

Carbon dioxide (CO2) corrosion is a recognized integrity threat worldwide. CO2 corrosion modeling has been used at both the design and operation phases of oil and gas pipelines and production tubing for the prediction of internal corrosion growth rates. Considerable gap exists between the prediction and the reality.


Since the classic carbon dioxide corrosion model published by C. DE WAARD and D. E. MILLIAMS in 1970s, more than a dozen of CO2 corrosion models have been developed over the past 40 years. Each of the model developers has incorporated their own laboratory and field data to produce a CO2 corrosion model.


CO2 corrosion modeling and CO2 corrosion prediction

The figure above shows a comparison of the measured corrosion growth rate and the corrosion growth rates predicted from twelve CO2 corrosion prediction models under a specific field condition.


None of the CO2 corrosion prediction models produced corrosion growth rate with reasonable accuracy. Without validation, facility owners and casual users of CO2 corrosion modeling programs have no way of knowing the accuracy or the reliability of the predicted corrosion growth rates.  The models differ in how it handles the calculation of pH, the treatment of fugacity, flow rate, scaling, oil wetting, effect of glycol, organic acids, NaCl and dissolved oxygen. Each model has its own limits, errors and uncertainties associated with the model. The user must evaluate the design and stream parameters and consider if any particular model can really be believed. In CO2 corrosion modeling, there is no such thing that one model fits all pipeline conditions. It is simply wrong for a contractor/consultant to use one (1) modeling software for all clients and under all pipeline conditions. Using CO2 corrosion modeling software is not like running an excel spreadsheet. The "all-in-all-out" approach in CO2 corrosion modeling is a formula for failure. The user of a CO2 corrosion modeling software must assess the input parameters, select suitable CO2 corrosion models, validate the selected model against the users' own or any 3rd party independent field/lab data before starting a CO2 modeling project.


It is always easier and better to validate the CO2 corrosion modeling software before commencing a modeling project than trying to validate the modeled results afterwards.


This 5-day specialized practical course covers fundamentals of corrosion, key factors influencing CO2 corrosion, and all the details on CO2 corrosion modeling for the prediction of internal corrosion in oil and gas pipelines. Specifically, the course will cover the overview of a dozen of empirical and mechanistic carbon dioxide corrosion models, CO2 corrosion model comparison, CO2 corrosion model selection, CO2 corrosion model validation and extensive hands-on modeling exercises.  A practical guide for CO2 corrosion modeling strategy is also presented.


This specialized practical course is available for in-house training, online and distance learning worldwide. It can also be customized to meet the specific needs of your organization.

 PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors


If you are involved in teaching or training, you may wish to purchase a complete set of the trainer's package for this training course. The trainer's package comes complete with ready-to-use PowerPoint slides (fully editable) and test bank (with answer keys). These ready-to-use PowerPoint slides contain high quality color photographs, illustrations, animations, audio and video clips. The test bank contains questions conveniently grouped into four categories: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions. The trainer's package is suitable for in-house training and university teaching (30 lecture hours). This is exactly the same package that WebCorr uses to deliver our current training course.

The one-time lump sum fee allows your organization to use the training package and also modify it. For example, your organization may modify the course contents and re-name/re-brand the course under your organizationís name.
