Laboratory Study of Electrokinetic Phenomena

P013 LABORATORY STUDY OF ELECTROKINETIC PHENOMENA Summary 1 When acoustic waves propagate through a fluid-saturated porous formation relative motion between the pore fluid and the solid matrix is generated and cation motion in the fluid is formed. The resulting fluid flow relative to the matrix produces an electric dipole - this is called the electrokinetic phenomena (or electrokinetic effect). To understand properties of electrokinetic (EK) phenomena EK signals and acoustic waves were measured on six kinds of fluid-saturated porous samples with different formation permeabilities. In the first experiment the time behavior of EK signal was measured at two different points
