The Study of the Physical Properties of Rocks Surrounding the Borehole which is essential for determining the geologic section, and particularly hydrocarbon and solid mineral deposits, as well as establishing physical foundations for assessing the section from surface observations. To this end, it is first of all necessary to study the effect of various heterogeneitie

The Polarization of Seismic Waves and its Potential for Studying the Rocks Surrounding the BoreholeAcademy of Sciences of the USSR, who in the fifties had already initiated studies of polarization, which resulted in the creation of the azimuthal method of seismic studies [9]. Strong distortion introduced by the low-velocity zone and by the upper portion of the geologic section, however, made the

Conclusionnt of the method of Vertical Seismic Profiling based on down-hole observations. Methodologically, the method is based on the correlational tracking along the vertical profile not only of the first arrivals, but of all the subsequent events on the seismogram as well.

The VSP Method for Refracted Wavese energy source, so that they cannot be used to identify the wave type reliably. Accordingly, it was presumed that the end could well be served by VSP. Down-hole observations at large offset distances from the shot-point have the following advantages over surface observations [14]:
