Abstract
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.
