An empirical model was previously developed to predict internal pitting corrosion of oil
and gas pipelines. This model is based on experiments carried out in the laboratory at high
pressure and high temperature under the operating conditions of the oil and gas pipelines.
The inputs are of two kinds: construction (pipe diameter, pipe wall thickness, and pipe
inclination) and operational (production rates of oil, water, gas, and solid, temperature, total
pressure, partial pressures of H2S and CO2, concentrations of sulphate, bicarbonate, and
chloride).
In this paper this model is further validated using field data obtained from seven
operating pipelines.
