Laboratory experiments and observation of pit growth rates in six operating fields have yielded a model to predict internal pitting corrosion of oil and gas pipelines. The experiments occured in a simulated high-pressure, high-temperature environment, while field observations took place for 4 years. The model works for transmission pipelines and sour or sweet production lines. This first part of two articles examines the pitting corrosion mechanism as well as problems in predicting internal pitting corrosion of oil and gas pipelines, before beginning an assessment of the parameters that influence internal pitting corrosion. The second, concluding article will continue this assessment and discuss both the predicting model and its validating observations.
