A substance and method for treating a subterranean formation using hydraul ic fracturing. A non-metallic, substantially deformable, proppant particle is "elastically flexible" or "plastically compressible" and adapted for use at concentrations which wi ll substantially create a partial monolayer. The method for treating a formation with a non- metallic deformable proppant, includes the steps of injecting a carrier fluid into th e formation, the carrier fluid carrying an amount of the deformable proppant, wherein the carrier fluid is injected at a pressure and a flow rate sufficient to create or open an existing fracture or fracture network in the formation, and placing at least a portion of the deformable proppant in the fracture, the deformable proppant forming substantially a partial monolayer in the fracture, and reducing the pressure and/or the flow rate sufficient to allow the fracture in the formation to at least partially close, wherein at least a portion of the deformable proppant remains in the fracture to prop open at least a portion of the fracture.</SD OAB> |
