ABSTRACT:
Vertical shear acoustic energy anisotropy of a subterranean formation is measured from a core sample of such formation. The core sample is shaped by having its outer surface cut to provide a pair of flat or planar surfaces along parallel spaced-apart planes. A pair of planar shear transducers are placed in contact with the pair of planar outer surfaces, one of the transducers being a transmitting transducer and the other being a receiving transducer. Shear acoustic energy is transmitted through the core sample in a basically elliptical pattern having an azimuthal direction within a plane parallel to the planar outer surfaces of the core sample. Any differences in travel time, attenuation, waveform or other acoustic properties for the acoustic energy transmissions in a plurality of differing azimuthal directions are a measure of the shear acoustic energy anisotropy of the subsurface formation.
