1. A method for performing a maintenance operation of a well in an oil/gas field, the method comprising:
identifying, based on a measured sequence of internal diameters of a tubular in the well with respect to longitudinal distances along the well, an extent of corrosion deposit in the tubular;
predicting, using a descaling model of the oil/gas field and based on the extent of corrosion deposit, expected descaling metal loss in the tubular of the well, wherein the descaling model correlates measured descaling metal loss in a reference tubular in a reference well with respect to a difference between a measured sequence of internal diameters of the reference tubular and an original internal diameter of the reference tubular, wherein the reference well is separate from the well;
calculating, based on the expected descaling metal loss, a tubular burst/collapse pressure for a predicted thickness of the tubular;
comparing the tubular burst/collapse pressure against a well operating pressure to generate a comparison result; and
performing the maintenance operation of the well based on the comparison result.
