    The paper presents an analysis of the acoustic wave forms obtained for the four holes located within the Przedkarpackie foredeep. In order to process and interpret the results of measurement GeoWin system was used (FWS Wave 2 application). Obtained value of compressional and shear waves velocity together with the velocity of Stoneley waves as well as the calculated Vp / Vs ratio allowed for the interpretation of the geological structure of the given rock centers. Designated interval times of the P and S waves with density profiling also enabled the determination of dynamic elastic modulus of rock. A juxtaposition of the dependency of velocity and bulk modules on the value of the Vp/Vs ratio, porosity and clay volume was made. On the basis of the results of the research the conclusions about the lithology, porosity and fracturing, as well as elastic and reservoir properties of rocks were drawn.
