ABSTRACT

Transient wave forms are present for a proposed logging tool which is capable of exploiting flexural and torsional waves, as well as more familiar axisymmetric wave types. Torsional waves appear especially promising for investigation invaded zones and other inhomogeneities. The design of a transducer capable of generating and detecting the various waves is described briefly.
