P018 Electrokinetic Capillary Measurements F. Schoemaker* (Delft University of Technology) D.M.J. Smeulders (Delft University of Technology) & E.C. Slob (Delft University of Technology) 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
