Abstract
A method for evaluating the extent of deterioration of pipes whereby an inspection instrument is passed through a length of casing to determine the extent of corrosive deterioration. The resulting measurements generated by the inspection instrument are processed to exclude those responses caused by the structural configuration of the casing length under inspection. The remaining responses are then analyzed to compile a detailed interpretation of the measurements including specific information regarding the state of deterioration of the length of casing under inspection.
