Abstract
A method includes alternating between (a) applying an electric current to a subterranean formation and (b) flowing an enhanced oil recovery (EOR) treatment fluid into a wellbore formed in the subterranean formation. The method includes flowing an aqueous salt solution into the wellbore to mobilize hydrocarbons within the subterranean formation after alternating between (a) and (b).
