**2.6 Electrokinetics potential**

Passing direct current (DC) through an oil reservoir generates an electrokinetics potential which causes electrophoresis, electromigration, electrochemical reaction, electro-osmosis and Joule heating [22]. The collective actions of these mechanisms improve formation rock permeability and porosity through the dislodgement and removal of pore linings in the form of colloids, thereby increasing pore sizes and creating new flow paths [22].
