Paper Number: SPE-205056-MS
... Generally, when a corrosion rate is predicted using a prediction model (regardless it is mechanistic, empirical or semi-empirical) it is assumed that the corrosion is of uniform/general corrosion (which is not the case for field failures as they are due to localized CO 2 corrosion...
