Abstract

A logging tool having opposed paired transducers located on opposite sides of the borehole in both the source and the detector and vnethods for its use. One source transducer expands while the opposed transducer contracts and one detector transducer emits a positive electrical signal in response to inward pressure, while the other emits a negative electrical signal in response to inward pressure. The tool thus exploits flexural waves along a borehole and minimizes interference by the faster-traveling compressional waves.
