1. An apparatus for determining an azimuthal stress variation in a tubular within a borehole, the apparatus comprising:

  • a logging tool including at least one transducer configured to generate a wave in the tubular;

    a plurality of receivers azimuthally distributed in the logging tool, each of the receivers configured to produce a signal responsive to the generated wave and an azimuthal stress distribution in the tubular; and

    at least one processor configured to determine from the signal from each of the plurality of receivers an indication of the azimuthal stress distribution in the tubular.
