“…More recent theoretical studies have included the pioneering approach of solving the fully coupled mechanical-electrodynamical problem [ 4 ], and recognition of the importance of slow Biot waves in SE conversion [ 5 ]. The modern state of the method, with many details on theory, modeling, and applications, has been described in comprehensive reviews [ 6 , 7 , 8 ]. Less common SE applications include planetary-scale analysis of electrokinetic fields caused by lunar tides [ 9 ].…”

The article is devoted to the study of the potential possibilities of using molecular-electronic sensors of seismic waves for field work using the seismoelectric method to explore the hydrocarbon deposits. The introduction provides an analytical review of the current state of research based on data from science magazines and patents. It is shown that at present, seismoelectric effects are at the stage of experimental implementation into the practice of field work for oil and gas geophysical prospecting. Further in the article, theoretical estimates and results of mathematical modeling of the manifestation of seismoelectric (SE) phenomena in the regions of hydrocarbon anomalies are presented, numerical estimates of the values of the seismic and secondary electromagnetic fields are given. The analysis of the results (on a tank and real gas condensate field) showed that the use of molecular-electronic geophones, which have a higher sensitivity and operate in a wider frequency range (up to 0.1 Hz), allows one to obtain higher signal-to-noise ratio. Thus, it has been experimentally established that the use of molecular sensors for recording seismic electric effects when searching for deposits is more preferable when carrying out field work.

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.
