Claim 13:
14. The method of claim 13 wherein:
the guided wave comprises an extensional wave and a flexural wave;
determining Vguided comprises determining, at each of the at least two of the frequencies, at least one of:
acoustic velocity of the extensional wave in the casing metal (Vextensional) utilizing the recorded data and geometric parameters of the module; and
acoustic velocity of the flexural wave in the casing metal (Vflexural) utilizing the recorded data and geometric parameters of the module; and

the method further comprises determining at least one of a compressional velocity of the casing and a shear velocity of the casing utilizing:
at least one of the at least one of Vextensional and Vflexural at each of the at least two of the frequencies; and
a predetermined dispersion curve.
