Significant advances have been made in the study of CO2H2S corrosion prediction and assessment in oil and gas production / transmission systems. A number of corrosion prediction models have been developed to predict corrosion rate in carbon steel. However, there is wide variability in these models. Many have successfully predicted the worst case corrosion rate but have not successfully addressed all the relevant and critical parametric effects. A Joint Industry Project (JIP) was conducted between 1997 and 2001 to characterize and gain insight into key parametric effects of H2S and wall shear stress in multiphase flowing systems.

This paper, Part I in the series, provides a review of the key issues in development of CO2/H2S corrosion prediction models in oil and gas systems, including a critical evaluation of electrochemistry, water chemistry, flow modeling, temperature, scaling, water/gas/oil ratios and elemental sulfur/aeration in corrosion prediction. Part II will provide a description of data from the JIP and key insights consequently gleaned that have been used to characterize parametric effects of H2S and wall shear stress effects on corrosion.

The NORSOK M-506 is an empirical model based on experiments undertaken in a single phase water flow loop. The data is from experiments with low content of iron ions in the water phase, and the model is thus regarded to give a fair representation of the maximum corrosion rate in a CO2 corrosion controlled system.
