Claim 0:
1. A method for determining properties of a downhole media on an exterior of a casing, comprising:
storing a set of division boundary values associated with downhole media located on an exterior of a casing in a computer readable medium, wherein the set of division boundary values consists of a divisional boundary for each of gas, low density liquid, high density liquid, micro-annulus materials, light-weight solids materials, and solids bonded to the casing;
conveying a logging tool through the casing in a downhole formation;
stimulating shear waves and flexural waves in the casing using the downhole logging tool;
obtaining a shear attenuation rate measurement and a flexural attenuation rate measurement within the casing responsive to the downhole media on the exterior of the casing;
comparing the measured shear attenuation rate and the measured flexural attenuation rate against the set of division boundary values;
determining one or more properties of the downhole media on the exterior of the casing based on the comparison of the measured shear attenuation rate and the measured flexural attenuation rate against the set of division boundary values, wherein the one or more properties comprise at least one of the measured shear attenuation rate and the measured flexural attenuation rate; and
determining the downhole media on the exterior of the casing based on the determined one or more properties.
