Processing of azimuthal electromagnetic pipe inspection data

A system comprising:

• an EM logging tool comprising:
• one or more transmitters disposed on the EM logging tool configured to transmit 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;
• and
• one or more receivers disposed on the EM logging tool configured to measure the eddy current in the one or more tubulars with the receiver on at least one channel to obtain a plurality of measurements;
• an information handling system configured to:
• measure the eddy current in the one or more tubulars with the receiver on at least one channel to obtain a plurality of measurements;
• form an EM log from the plurality of measurements;
• extract an eccentricity pattern from the EM log;
• and
• inspect at least the eccentricity pattern and EM log to identify defects in tubulars, wherein inspecting at least the eccentricity pattern further comprises estimating an eccentricity ratio at least on rearranging an order of sensors.
