ABSTRACT:
An acoustic well logging method and apparatus utilizes a rare earth acoustic transducer to provide low frequency acoustic energy within the borehole, and characteristics of a subsurface geological formation, such as the formation dip, may be obtained by measuring the amplitude of the shear wave and combining that amplitude with known data comprising a graph of shear wave amplitude plotted against incidence angle at known frequencies.
