... velocity can be directly measured from the quadrupole data in the 5-to 12-kHz frequency range without dispersion correction. Formation azimuthal shear-wave anisotropy introduces additional complexity to the quadrupole data interpretation. The anisotropy, when large, produces fast and slow quadrupole waves...

... field measurements have been made for various fast and slow formations. In a frequency range of 2–10 kHz, the monopole acoustic data consist primarily of a collar (extensional) wave and Stoneley waves. The dipole data consist of both collar and formation flexural waves. The quadrupole data are least...

..., acoustic logging is performed in a very broad frequency range, from 200 Hz up to 35 kHz (Homby et al., 1989; Paillet, 1980). Because the fracture fluid motion excited by logging acoustic waves is dynamic in nature (Johnson et al., 1987; Tang and Cheng, 1988), it is expected that the model that accounts...
