Applications of Corrosion Models to the Oil and Gas Production

Carbon dioxide corrosion models, including empirical models, semi-empirical models, and mechanistic models, 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, determining inspection frequency, and understanding the results obtained from in-line pipeline inspection tools.
