WebThe inverted pore-aspect-ratio spectrum is input into the wave theory to predict the velocity dispersion of the rock in the full frequency range. The predicted dispersion and its variation trend with pressure agree with the data measured in the (2–200, 10 6 ) Hz range at various differential pressures, whereas the modeling using a single ... WebQ-estimation methods, the spectrum ratio (SR) method is the basis for many other similar ones, e.g., the energy ratio method (Wang et al., 2015). SR assumes that the logarithm of the ratio of the amplitude spectra of two waves is a linear function of frequency, and the slope of this function is related to the reciprocal Q.
