The main aim of this work is physical interpretation and experimental verification of the method based on a recording of seismoelectric effect in natural Earth's seismic and electromagnetic fields. In this case, a deposit is described by a model of the flat condenser in which ion-conducting medium (deposit waters) serve as plates and deposited hydrocarbons serve as a dielectric layer. The considered frequencies of both types of fields are in the range of 0.1-20 Hz. The calculated curve of electric field distribution on Earth's surface generated by deposit seam induced by natural electric and seismic fields of the Earth's crust is given. Experimental data of observations of seismoelectric effect in passive fields are presented obtained in 2014-2017 at Bystryansky gas condensate field (Krasnoyarsk Krai, Minusinsk district) by the recording of passive electric and seismic fields as well as measurement of their cross-correlation.
