Results of the computer program FalaFWS for processing and interpretation of acoustic full waveforms in deep and shallow rock formations are presented. The goal of the paper is to show a possibility of obtaining correct values of elastic properties of shallow formations on the basis of acoustic waveforms recorded with standard device. Results of measurements with a device constructed for deep wells and results of data interpretation using computer program written for that device provide an interpreter with correct values of dynamic elastic parameters in shallow, poorly consolidated rocks. Field examples are given to confirm the presented analysis.
