The purpose of the present research is to experimentally confirm the seismoelectric effects of the second type on the physical model, which is represented by a tank filled with sand (2.1 x 1.32 x 3.2 m). Analysis of the current state in the field of hydrocarbon search using seismoelectric effects was carried out. Physical modeling of microseismic and natural electromagnetic field was performed applying acoustic emitter and grounded electrodes at the tank edges; registration was carried out with the help of three axial seismic receivers manufactured by GS and grounded dipole using non-polarizing electrodes of VIRG design. The results show that the maximum of the cross-correlation function is highly noisy, and recording seismoelectric effects on physical models of such sizes using the existing element base is not possible, thus, it is necessary to either increase the sensitivity of the receiving equipment along with an increase in the size of physical models or increase the signal accumulation time from 20 minutes or more.
