- The knowledge of elastic parameters, especially of P-wave and S-wave velocities as a function of depth, is important for interpretation of seismic waves and well log data. Information on velocities of P and S waves is obtained from quantitative interpretation of acoustic full waveforms recorded in a borehole in addition to standard PA measurements. When acoustic full-waveform data are not acquired in boreholes, one of methods for calculating P-wave and S-wave velocities is their estimation with the use of theoretical models of porous media. This requires introduction of several lithological and reservoir parameters of rocks that are obtained from interpretation of well log data. Other methods of S-wave velocity calculation is based on statistical relationships between velocities of both types of waves obtained on the basis of laboratory studies. In this paper, the theoretical Biot-Gassmann's and the Kuster-Toksöz's models are briefly described and results of calculations of P-wave and S-wave velocities are given. The empirical relationships between VP and VS, which are applied in many computer programs used by major geophysical companies, were also analysed.
