Carbon dioxide corrosion models, including empirical, semi-empirical, and mechanistic ones, have been developed to predict corrosion of carbon steel for the past several decades. Although the mechanisms of carbon dioxide corrosion are well understood through laboratory investigations, it is still challenging to apply corrosion models to predict corrosion in actual oil and gas fields. This paper will discuss the applications of corrosion models in oil and gas production, which include calculating corrosion allowance and making prediction of facilities life in the design phase, providing guidance in corrosion management in the production phase, understanding the results obtained from in-line pipeline inspection tools, determining inspection frequency, and serving as a tool for improvement, trouble-shooting, and failure analysis.
