The coupling between seismic and electromagnetic waves in a fluid-saturated porous medium is essentially controlled by the electrokinetic effect. The inverse effect of the seismoelectric conversion, the electroseismic conversion, is investigated experimentally in the laboratory. The electric field induces movement of the ions in a pore fluid relative to the solid matrix. The interaction between...

Seismic to electromagnetic wave conversion has been proposed as a possible exploration method. We present laboratory measurements of the conversion of an acoustic wave into electric potential, which occurs at a fluid/porous-medium interface. The conversion is measured for artificial porous media and Berea sandstone. Recorded electric potentials are smaller for largegrain samples. We also show v...

Seismoelectric phenomena in sediments arise from acoustic wave-induced fluid motion in the pore space, which perturbs the electrostatic equilibrium of the electric double layer on the grain surfaces. Experimental techniques and the apparatus built to study the conductivity dependence of the electrokinetic (EK) effect are described and outcomes for studies in loose glass microspheres and medium-...
