... The dissipation factors (1/Q) of three Biot waves, S-waves, fast P-wave and slow P-wave are derived as the concise and explicit expressions which enable to investigate the dependence of the waves characteristics on the degree of wave inhomogeneity. It is found that if the inhomogeneity parameter...

.... To overcome this problem, we propose an alternative easy-touse expression that is solely based on the signal-to-noise ratio and the period corresponding to the dominant frequency in the data. The new expression yields comparable results with that of CRB. The numerical example demonstrates that the new...

... is Gaussian shape, which leads to the errors of CFS method; The PFS method is based on the Ricker shape assumption but the peak frequency is susceptible to noises, which causes instability. Combining the two methods, we modified the expression of Q based on the two methods and applied it to the oil and gas...
