摘要： Method of using direct current (DC) electrokinetics to enhance oil production from carbonate reservoirs The method comprising the steps of selecting an underground formation comprising an Oil-bearing carbonate reservoir, positioning two or more electrically conductive elements at spaced apart locations in proximity to said formation, at least one of said conductive elements being disposed in or adjacent to a bore hole affording fluid communication between the interior of said bore hole and said formation, passing a controlled amount of electric current along an electrically conductive path through said formation, said electric current being produced by a DC source including a cathode connected to one of said conductive elements and an anode connected to another of said conductive elements, said electrically conductive path comprising at least one of connate formation water and an aqueous electrolyte introduced into said formation, and withdrawing oil from at least one of said bore holes.
