Abstract

A method for performing a maintenance operation of a well in an oil/gas field. The method includes identifying an extent of corrosion deposit of the well, predicting, using a descaling model of the oil/gas field and based on the extent of corrosion deposit, expected descaling metal loss in a tubular of 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.
