Several prediction models for CO2 corrosion of oil and gas pipelines have been developed. Some of the models are based on mechanistic modeling of the different processes involved in CO2 corrosion of carbon steel, while other models are mainly based on empirical correlations with laboratory or field data. The models differ considerably in how they predict the effect of protective corrosion films and the effect of oil wetting on CO2 corrosion, and these two factors account for the most pronounced differences between the various models. The paper gives an overview of prediction models used in the oil and gas industry for evaluation of CO2 corrosion of carbon steel.
