Abstract
Improved methods of propping a fracture in a subterranean zone whereby the subsequent flow-back of the proppant is prevented are provided. The methods basically comprise the steps of placing proppant and a magnetized material in said fracture while maintaining the fracture open and then allowing the fracture to close on the proppant and magnetized material whereby the magnetized material clusters in voids and channels in the proppant bed formed.
