Claim One:
1. A method for predicting downhole casing leaks of hotspots, comprising: obtaining, by a data processing apparatus and from corrosion logs generated by an electromagnetic (EM) logging tool, raw EM corrosion data for a hotspot, wherein the raw EM corrosion data includes a metal thickness loss value for the hotspot; determining, by the data processing apparatus, a corrosion parameter based on the raw EM corrosion data, wherein the corrosion parameter includes a corrosion rate that is calculated based on an original thickness value, a remaining thickness value, and a number of years; generating, by the data processing apparatus, a probability distribution curve for the corrosion parameter; generating, by the data processing apparatus, a corrosion severity classification matrix based on the probability distribution curve, wherein the corrosion severity classification matrix includes a plurality of corrosion severity classes and cutoff values for each of the plurality of corrosion severity classes; assigning, by the data processing apparatus, the hotspot into one of the plurality of corrosion severity classes based on a comparison of the cutoff values for the plurality of corrosion severity classes in the corrosion severity classification matrix and the corrosion parameter of the hotspot; and generating, by the data processing apparatus, a service alert for the hotspot based on the assigned corrosion severity class.
