A method and system comprising disposing an electromagnetic (EM) logging tool in a wellbore, wherein the EM logging tool comprises: one or more transmitters disposed on the EM logging tool; and one or more receivers disposed on the EM logging tool. They system and method may further comprise an information handling system configured for transmitting an electromagnetic field from the transmitter into one or more tubulars to energize the one or more tubulars with the electromagnetic field thereby producing an eddy current that emanates from the one or more tubulars; measuring the eddy current in the one or more tubulars with the receiver on at least one channel to obtain a plurality of measurements. Finally, forming an EM log from the plurality of measurements; extracting an eccentricity pattern from the EM log, and inspecting at least the eccentricity pattern and EM log to identify defects in tubulars.
