Abstract

A method of electrochemically treating a hydrocarbon-bearing formation is provided. The method includes electrochemically treating an aqueous fluid to provide a first fluid having a first electrochemical potential and a second fluid having a second electrochemical potential. The first electrochemical potential the second electrochemical potential have opposite signs. The method then includes introducing an amount of the first fluid into the hydrocarbon bearing formation, and then an amount of a spacer fluid is introduced into the hydrocarbon-bearing formation. An amount of the second fluid may be optionally introduced into the formation. The steps of introducing the fluids are repeated until an end point is reached. A system for electrochemically a hydrocarbon-bearing formation is also provided.
