Data related to tubing corrosion in an oil field have been compiled and analysed in terms of angle of well tubing deviation, watercut and fluid velocity. Using a semi-empirical formula for C02 corrosion prediction, it was possible to model the effect on corrosion of the light crude oil produced from a field in the Middle East by means of a multiplier for the corrosion rate, the oil factor. A good level of correlation was achieved between field measured corrosion rates and calculated values using the model established for this specific field. The model was incorporated in a user-friendly computer programme suitable for analysing ongoing corrosion risks and anticipating future field developments.
