Abstract
Apparatus and methods for identifying drilling cuttings downhole by extracting an echo from a pulse-echo waveform acquired utilizing a downhole ultrasonic tool having an acoustic device. An energy before echo profile preceding the extracted echo is determined, and then the energy before echo profile is processed to remove effects associated with the acoustic device. A cutting is then identified from the processed energy before echo profile.
