• P-wave slowness
• S-wave slowness
• acoustic full wave forms
• FalaFWS application
• Estymacja program
• acoustic wave frequency
• seismic wave frequency

Three different methods of building de tailed velocity models for seismic interpretation are explained and discussed in terms of their advantages and limitations. All of the pro posed methods are based on the analysis of acoustic well logs. An application of acoustic full wave form measurements, as well as the FalaFWS and Estymacja software, is presented as a tool for determining P-wave and S-wave slowness (transit time interval, velocity reciprocal). Well log data from several wells, located near the special re search seismic transect in the Polish Low land, were processed using the methods proposed. The results of data analysis are presented for a depth section of up to 3623 m for the lithostratigraphic units, recorded from the Sroda Wielkopolska 5 (SW5) well. The results of P-wave and S-wave slowness filtering, used to up scale well log data to a seismic scale of resolution, are shown for the en tire geological profile of the SW5 well.
