Abstract
A method and system for estimating a thickness of at least one casing string in a cased hole may comprise obtaining a plurality of induction measurements from a plurality of channels using a casing inspection tool, computing a quality vector for the plurality of channels, wherein each element of the quality vector is a numeric output, identifying the plurality of channels is a high-quality or a low-quality based at least in part on an evaluation of the quality vector to obtain a high-quality subset of the plurality of channels and a low-quality subset of the plurality of channels, and estimating the thickness of the at least one casing with an inversion using a high-quality subset of the plurality of channels. A system may comprise a multi-channel induction tool and an information handling system. The multi-channel induction tool may comprise at least one transmitter and at least one receiver.
