ABSTRACT:
The present invention provides improved methods of placing proppant in fractures formed in a subterranean zone to prevent the subsequent flow-back of the proppant with fluids produced from the zone. The methods are basically comprised of the steps of depositing a mixture of hardenable resin composition coated proppant and uncoated proppant in the fractures and then causing the resin composition to harden into stationary permeable masses in the fractures.
