US Patent 7334636 Methods of creating high-porosity propped fractures using reticulated foam

One embodiment of the prevent invention provides a method of creating a high porosity propped fracture comprising creating a slurry comprising a treatment fluid, proppant particulates, pieces of reticulated foam having cells, and an adhesive substance such that the adhesive substance at least partially coats the proppant particulates and such that the proppant particulates become substantially embedded within the cells of the reticulated foam; and, depositing at least a portion of the reticulated foam fragments having proppant particulates embedded therein in one or more fractures within a portion of a subterranean formation so as to form a high porosity propped fracture.
