METHODS AND SYSTEMS FOR PROCESSING BOREHOLE DISPERSIVE WAVES WITH A PHYSICS-BASED MACHINE LEARNING ANALYSIS

摘要

Systems and methods are provided for determining a formation body wave slowness from an acoustic wave. Waveform data is determined by logging tool measuring the acoustic wave. Wave features are determined from the waveform data and a model is applied to the wave features to determine data-driven scale factors The data-driven scale factors can be used to determine a body wave slowness within a surrounding borehole environment and the body wave slowness can be used to determine formation characteristics of the borehole environment.
