SUMMARY
We present laboratory measurements of dynamic permeability on samples consisting of capillary tubes.
The dynamic permeability is a measure of the fluid flow response to an applied external oscillating
pressure gradient such as exists in seismic waves. Existing theoretical models are validated. Moreover, in
our laboratory set-up, also the Electrokinetic coupling is investigated. This coupling describes the fluid
flow response to an external electric field such as exists in recent field tests where a high-voltage sources induces seismic responses recorded by geophones. In our set-up, the pressure field is externally applied and the induced electric field is measured.
