Abstract
A method of fracture fluid clean-up from a fracture by assisting Darcy flow with electro-osmotic effects is provided. Proppants having suitable surface potential, and fracture fluids having suitable electrical conductivity are employed. A suitable electric field is imposed, using electrodes placed on the surface or in adjacent wells. The current creates an electro-osmotic flow that carries fluid to the wellbore.
