Abstract
According to the present invention, the production of petroleum from a petroleum-bearing subterranean formation penetrated by a wellbore is accomplished by (a) fracturing the subterranean formation and injecting a conductive proppant into the fracture, the conductive proppant comprising particles which are at least partially coated with a heat hardenable, conductive resin to create a fluidly and electrically conductive fracture in the formation; (b) passing an electrical current into the formation through the wellbore to heat the formation and harden the conductive resin thereby at least partially aggregating the particles and retaining the particles in the fracture and heating the fracture and the subterranean formation in the vicinity of the fracture.
