A comprehensive corrosion prediction model for multiphase oil and gas production and transmission systems was enhanced by incorporating a Top-of-Line corrosion capabilities. Key issues in development of the enhancements are discussed, including evaluation of an improved flow model implemented to facilitate accurate flow predictions. The model was evaluated with parameters commonly encountered in oil and gas production environments as well as transmission systems, and effects of various parameters on corrosion rates are described. Corrosion rates obtained from the enhanced model are compared with actual field and lab testing data as a basis to quantify accuracy and efficacy of the model.
