S U M M A R Y The electrical current density generated by the propagation of a seismic wave at the interface characterized by a drop in electrical, hydraulic or mechanical properties produces an electrical field of electrokinetic nature. This field can be measured remotely with a signal-to-noise ratio depending on the background noise and signal attenuation. The seismoelectric beamforming appro...

The seismoelectric effect of porous media is the main basis for logging. At present, most studies on in unsaturated adopt model pores with continuous distribution gas and liquid. There a lack theoretical research micro mechanism discrete phase, existing do not consider electric double layer at gas–liquid interface effect. Based capillary model, this work adopted phase combined theory seepage pr...

Abstract We present an analytical model to compute frequency-dependent relative permeability functions for partially saturated porous media accounting viscous coupling effects. For this, we consider the oscillatory motion of two immiscible fluid phases and solve Navier–Stokes equations at pore scale using suitable interface conditions between fluids. These calculations are combined with general...
