摘要: In a porous medium the fluid flux and electric current density are coupled, so that streaming potentials generated by fluids moving through media fractures. These electrokinetic phenomena induced relative motion between rock because of presence ions within water. Both steady-state transient flow can induce electrokinetics phenomena. It has been proposed to use this coupling detect preferential paths, faults contrast in permeabilities crust, deduce hydraulic conductivity. This chapter proposes comprehensive review rocks sediments different approaches properties various contexts.
