Abstract
A method for estimating a borehole condition using a Stoneley measurement is provided. The method comprises recording acoustic waveforms obtained from one or more receivers, applying a time window to the acoustic waveforms to extract Stoneley components, computing energies of the Stoneley components within a frequency band, and obtaining at least one of borehole conditions based on the energies of Stoneley components.
