Vertical seismic profiling (VSP) technology is increasingly being used in the fields of earthquake seismology and tectonics. This is motivated in part by the growing number of oil field microseismic monitoring surveys, but more so by projects that in

First break times (FBT) of P-wave and S-waves picked from three-component (3C) VSP data were used to produce tomographic velocity profiles and Vp/Vs ratio distribution. 3C Eigenvalue rotation is critical for correctly identifying and accurately picki

Two types of shear waves have been recorded from a land VSP survey at zero and far offset locations with a vertical Vibroseis source. The two shear waves polarized normal to the compressional waves and traveled at different velocities, indicative of

This paper presents an application of seismic tomography to determine the velocity field on the flanks of a steep, deeply-buried salt body, enabling us to determine the configuration of the flank of the salt body. The method is applied to the Anadark
