Abstract
The present invention provides compositions and methods for enhancing subterranean well productivity by enhancing fracture conductivity. A method of increasing the conductivity of a fracture in a portion of a subterranean formation comprising providing a slurry comprising a fracturing fluid, a degradable material, and proppant particulates coated with a tackifying agent; allowing the degradable material to become at least temporarily attached to the tackifying agent coated onto the proppant particulates so as to avoid substantial segregation of the degradable material from the proppant particulates within the slurry; introducing the slurry to the fracture and allowing the proppant particulates and degradable material to form a substantially uniform particulate pack; and, allowing the degradable material to degrade and produce a particulate pack having voids therein.
