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.

- Modeling of uniform CO2 corrosion of mild steel in gas transportation systems: A review (2016, methodology): “…functions used in these models may originate from rudimentary approximations of the fundamental physicochemical processes underlying the corrosion phenomena, however, the more elaborate aspects are accounted for by introducing correction factors in the model (Ne si c et al., 1997; Nyborg, 2002).”
- Film former corrosion inhibitors for oil and gas pipelines - A technical review (2018, background): “It causes higher corrosion rates than what was expected from corrosion in strong acids in the same pH. CO2 dissolves in water and forms carbonic acid, which is weaker in comparison to mineral acids (Nyborg, 2002; Pots, 1995).”
