Method for effecting fluid flow in porous materials

摘要

A method of effecting fluid movement in porous geological media is provided. The method applies a sequence of voltage pulses between spaced apart first and second electrodes having a region of porous geological medium there between. A first portion of the voltage pulse provides an electro-osmotically active first potential difference to effect fluid movement. A second portion of the voltage pulse provides a potential difference opposite polarity to the first.
