ABSTRACT:
A sonic transmitter and receiver are employed to locate and evaluate zones of significant porosity in the proximity of a borehole. Continuous wave and pulse techniques are used to locate the zones and to determine the void dimensions by means of frequency domain signatures. Both through-transmission and reflection methods are employed. The technique is considered especially useful for locating fluid-filled vugular zones.
