In this study, based on the results obtained from laboratory measurements of compressional
and shear-wave velocities on 39 limestone rock samples in both dry and saturated states, a few
relationships have b<;,en found between physical properties of the rocks.
The data demonstrates simple systematic relationships between compressional and shear wave
velocities for both dry and saturated states. Also a few model theories have been used to predict
saturated velocities from dry velocities among those are Gassmann (1951) and Biot (1956)
theories and wyllie et al. (1956) and Raymer et al. (1980) relationships. The measurements also
show that the dry and saturated moduli decrease with increasing porosity. Our data show
excellent linear relationships between bulk and shear moduli normalised by density and V
