Abstract
A method of enhancing oil production from an oil bearing formation includes the steps of providing a first borehole in a first region of the formation and a second borehole in a second region of the formation. A first electrode is positioned in the first borehole in the first region, and a second electrode is positioned in proximity to the second borehole in the second region. A voltage difference is established between the first and second electrodes to create an electric field across the plugging materials. The electric field is applied to destabilize the plugging materials and improve oil flow through the formation.
