Developing computer-based problem solving models that predict corrosion in oil and gas systems is a complex task, requiring integration of multiple scientific and engineering disciplines. In addition to capturing and characterizing the role of primary environmental, fluid flow and metallurgical variables contributing to the mechanisms of corrosion, it is necessary to validate the performance of the model within the context of field experience. This paper describes the evolution of a corrosion prediction computer model for oil and gas systems in terms of critical parameters such as system pH, CO2, H2S, temperature and fluid dynamics factors and details a methodology wherein the model is applied to assessing corrosion for a real life field application.
