Abstract
The addition of a thermoplastic material in intimate mixture with particulates for fracturing, gravel packing or other formation treatments decreases or substantially eliminates the flowback of particulates whether proppants or formation fines while stabilizing the particulate within the formation. Preferred thermoplastic materials include polyolefins, polyamides, polyvinyls and cellulose derivatives in the form of particles, ribbons or flakes.
