Abstract
The present invention relates to high porosity propped fractures and methods of creating high porosity propped fractures in portions of subterranean formations. Another embodiment of the present invention provides a method of forming a high porosity propped fracture in a subterranean formation, comprising providing a slurry comprising a fracturing fluid and proppant particulates coated with an adhesive substance; introducing the slurry into a portion of a fracture within the subterranean formation; and, depositing the proppant particulates into the portion of the fracture within the subterranean formation so as to form a high porosity propped fracture. Another embodiment of the present invention provides a high porosity propped fracture comprising proppant particulates substantially coated with an adhesive substance wherein the propped fracture has a porosity of at least about 50%.
