INTRODUCTION

Quantitative calibration of amplitude variation with offset data by seismic modeling requires S-wave velocity information. The purpose of this paper is to review the means of acquiring S-wave velocities in boreholes by: (1) laboratory measurements on core samples, (2) pseudo-shear velocity logs derived from empirical trends and conventional well log data, (3) conventional full-waveform sonic logs, (4) direct S-wave sonic logs, and (5) multicomponent vertical seismic profiles with “point” or horizontal sources.
