Abstract
The first experimental measurements of the cross-correlation function (CCF) of the Earth’s seismic and electrical noise were carried out in two areas of the Minusinskoe gas condensate field in 2014 and 2015, using a VPEMPZ-M1 (Shum-6) two-channel geophysical device developed at Siberian Federal University. The Earth’s seismic noise and electrical noise in the frequency range 0.1-20 Hz were received by a geophone and an electric dipole, respectively. In both cases, a productive pool at depths of 1800-2000 m had a maximum CCF value five to seven times greater than the normal background. This phenomenon indicates the occurrence of the seismoelectric effect in passive fields.
