Homomorphic Processing Of Acoustic Logging Data

Abstract

A new processing method, which we developed for the guided waves generated during acoustic logging, accurately estimates the wavenumber when only a few seismograms are available or when the seismograms are irregularly spaced. The estimates of the attenuation coefficient are seemingly accurate when many seismograms are available but are inaccurate when only a few seismograms are available. The new method does not generate any spurious estimates as the Prony-based method does.
