Abstract: This paper continues a series of publications dedicated to lab assessment of efficiency of carbon dioxide corrosion inhibitors at the oilfield pipelines of West Siberia region. It reviews the results of tests performed on “rotating cylinder” and “rotating cage” facilities. The article reviews the effect of temperature, specimen surface condition, flow velocity, presence of a hydrocarbon phase and inhibitor concentration on corrosion rate and protective properties of a wide range of commercial inhibitors. Recommendations on specific inhibitor test conditions are given to assess their applicability for protection of water lines, oil pipelines with low watercut and oil pipelines with high product watercut.

Keywords: corrosion inhibitors, test methods, oilfield pipelines
