METHOD AND SYSTEM FOR FRACTURING SUBTERRANEAN FORMATIONS WITH A PROPPANT AND DRY GAS

摘要

A method and system for stimulating underground formations is disclosed . The method includes injecting pressurized gas and low concentrations of proppant material at a rate and pressure sufficient to fracture the formation and all ow for placement of the proppant in the fracture, followed by allowing the fracture to close on proppant to create a high-permeability flow channel without the use of liquid fracturing fluids or liquefied gases.
