Abstract: A mathematical model of a homogeneous geological medium with methane cavities was developed. Based on the results of the calculations, wave patterns of the distribution of the velocity modulus in the models and seismograms of the recording of various velocity components on the receivers of reflected signals were obtained. The simulation results demonstrated the possibility of identifying the number of methane cavities by the waves reflected from them.

Keywords: seismic prospecting, methane cavities, grid-characteristic method
