The addition of fibrous mixtures in intimate mixtures with particulates for fracturing and gravel packing decreases or eliminates the undesirable flowback of proppant or formation fines while stabilizing the sand pack and lowering the demand for high polymer loadings in the placement fluids. Fibers
The addition of fibrous mixtures in intimate mixtures with particulates for fracturing and gravel packing decreases or eliminates the undesirable flowback of proppant or formation fines while stabilizing the sand pack and lowering the demand for high polymer loadings in the placement fluids. Fibers are useful for forming a porous pack in the subterranean formation. In some cases, channels or fingers of void spaces with reduced concentrations of proppant may be introduced into the proppant pack.

A method of treating an underground formation penetrated by a wellbore using a fluid suspension, comprising the steps of: (a) providing a fluid suspension, said suspension comprised of a fluid, a particulate material, and a solid material, the solid material being selected from the group of solid materials consisting of metal, polymers, ceramics and glass; (b) pumping the fluid suspension downhole through a wellbore; (c) depositing the fluid suspension in the formation; (d) flowing back fluid from the formation, thereby forming a matrix of solid material and particulate material; and (e) reducing migration of particulate material from the matrix into the wellbore. A method of reducing the production of proppant from a well after fracturing a subterranean formation penetrated by the well, comprising: (a) pumping a fluid from the surface of the ground through a wellbore and into a subterranean formation, the fluid comprising a viscous liquid, proppant, and shavings or discs of polymer material, (b) forming a matrix within the subterranean formation, the matrix comprising the proppant and polymer material in close association with each other, and (c) reducing production of the proppant from the well.
