Evaluation of full wave sonic (FWS) data for rock properties such as fractures and dipping boundaries. often requires qualitative analysis of visually distinct wave patterns. Conventional waveform plots do not reveal all the information available in FWS data. With the application of a complex waveform analytical method called "Instantaneous Waveform Characteristics" (IWC) analysis and with the use of color encoded displays called "colorgrams", additional FWS characteristics, helpful to formation description, can be observed and interrelated.
