Beskrivelse
Summary: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 large grain samples. We also show variability of the conversion over a time span of 120 hours.
