Abstract
Traditional borehole sonic measurements identify arrival of the refracted wavefield along the borehole to determine acoustic slowness close to the borehole. Evolution of this technology to arrayed receivers and downhole digitization of the wavefield has allowed evaluation of both compressional and shear slownesses through coherence semblance techniques.
