Observation of the seismoelectric effect in a gas condensate field in the Earth’s natural electromagnetic and seismic noise of 0.1–20 Hz

Abstract

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 higher than the normal background, indicating the occurrence of the seismoelectric effect in passive fields.
