One of the most fundamental issues in current day corrosion research is assessment of corrosion rates in steels and determination of corrosivity of typical operating environments in oil and gas production. Such an assessment requires an understanding of the role of primary environmental and metallurgical variables and underlying mechanisms of corrosion. A corrosion prediction computer model that assesses corrosivity of oil and gas systems in terms of pH, CO2, H2S, temperature and flow has been developed. This paper describes further research undertaken by the authors in refining the corrosion prediction model and in assessing the role of H2S scale formation and growth, role of hydrocarbons in promoting/inhibiting corrosion and the role of steel metallurgy in corrosion assessment.
