Microseismic sounding method observations by Rayleigh waves in the territory of the Astrakhan gas condensate field are carried out. The spatial variations of intensity of natural microseismic background in the frequency range from 0.03 Hz to 1 Hz are analyzed. Estimates of three-dimensional distribution of relative velocities of S-waves to depths of several tens of kilometers are obtained. New data on the structure of Astrakhan gas condensate field as a result of research, carried out by the microseismic sounding method, are obtained.
