METHOD AND DEVICE FOR BOREHOLE ACOUSTIC SIGNAL PROCESSING Russian patent published in 2008 - IPC G01V1/48 

Abstract RU 2334252 C2

FIELD: physics.

SUBSTANCE: method of extraction and/or removal of the concerned signal, including: initiation of acoustic waves using well-logging system having, at least, one transmitting device and, at least, one receiver; automatic filtering of the concerned signal from acoustic signal data received with, at least, one receiver, through calculation of the first coherence measure, including the concerned signal, and displaying of the first coherence measure to time domain, and self-filtered acoustic signal data processing based on coherence measure. Specified method is realised in number of versions using corresponding devices.

EFFECT: improved quality of registered signal interpretation.
