Abstract
A method for determining the type of corrosion present in deteriorating pipes. 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 of one of the measurements are then analyzed to provide useful information regarding the type of corrosion present at defects in the casing length under inspection and to further provide information necessary to make a detailed analysis of the defects present in the casing length under inspection.
