Abstract
An apparatus and method are disclosed for producing thick tar sand deposits by electrically preheating paths of increased injectivity between an injector and producers, wherein the injector and producers are arranged in a triangular pattern with the injector located at the apex and the producers located on the base of the triangle. These paths of increased injectivity are then steam flooded to produce the hydrocarbons.
