Abstract
The wave tomography method is a finite difference analog of the classical seismic ray tomography. The computational investigation is reported in the article. The proposed approach allows identification of velocity anomalies in jointed rock zones of methane accumulations if the sizes of these zones are comparable with the dominant wavelength of seismic sounding.
