A study of sonic logging in a cased borehole

Shu-Hong Chang, A. H. Everhart

Abstract

A study was undertaken to investigate the feasibility of sonic logging in a cased borehole. Results were obtained from a scaled-model laboratory experiment and from computer simulations. The waveforms from the computer model indicate that sonic logging can be successful in bonded and unbonded cased holes. A slowness-time semblance signal processing technique is used to obtain wave velocities from waveforms.
