An apparatus and method are disclosed for producing thick tar sand deposits by electrically preheating paths of increased injectivity between an injection well and production walls, wherein the horizontal sections of the injections and the production wells are arranged in a triangular pattern with the horizontal section of the injection well located at the apex and the horizontal sections of the production wells located on the base of the triangle. These paths of increased injectivity are then steam flooded to produce the hydrocarbons.
