Risk-oriented approach to the selection of corrosion inhibitors for industrial applications based on field and laboratory tests

Authors: S.E. Zdolnik , S.N. Vagaytsev (Bashneft JSOC, RF, Ufa) , I.S. Sivokon (Transenergostroy OOO, RF, Moscow), A.T. Faritov , L.P. Khudyakova (IPTER GUP, RF, Ufa)

Key words: corrosion inhibitors, test methods, oil-field pipelines, the risk, conditions of corrosion.

Based on the analysis results of experimental-field and complex laboratory tests of 11 corrosion inhibitors their ranking is carried out and the areas of their effective application in real piping systems are determined. A comparison of the conditions of corrosion behavior in various laboratory tests and in the most risky parts of pipeline is executed. The risk-oriented approach to the selection of corrosion inhibitors for industrial applications and the main stages of its implementation are formulated.
