This study examined two laboratory methods used to determine dynamic elastic constants: (1) the ultrasonic pulse method and (2) the resonance method. A limited numer of carbonate rock core samples were taken from several different wells located in the Foresudetic Monocline in Western Poland and seven sandstone samples were collected from outcrops in southern Poland. The date trends indicate that the values of elasticity are strongly dependent on the lithology, porosity and water saturation of rocks. The module values in carbonate rocks are larger than the module values in sandstone by an order of two in all samples with small porosity. Thus, in order to estimate the relationship between elasticity and the petrophysical parameters of rock we must study rocks taken from the same lithological group.
