1. A method for treating a well penetrating a subterranean formation under conditions of from 2,500 to 10,000 psi closure stress, comprising introducing into the well a proppant of a selectively configured porous particulate material, the selectively configured porous particulate material being a porous particulate material manufactured with a glazing material or treated with a penetrating layer, coating layer or glazing material, wherein the selectively configured porous particulate material exhibits crush resistance under the closure stress conditions and further wherein the strength of the selectively configured porous particulate material is greater than the strength of the porous particulate material.
