Abstract: This paper is a continuation of a series of publications related to laboratory assessment of the performance of carbon dioxide corrosion inhibitors for oilfield pipelines in the West Siberian region. The test results obtained in U-shaped glass cells are considered. The effects of temperature, carbon dioxide content, test duration, specimen surface condition, presence and volume of a hydrocarbon phase, and inhibitor concentration on the corrosion kinetics and protective properties of a wide range of industrial inhibitors are analyzed. Recommendations are given on specific inhibitor test conditions to be used for assessment of inhibitor suitability for the protection of water pipelines and oil pipelines with low watercut.

Keywords: corrosion inhibitors, corrosion tests, oilfield pipelines
