Abstract: A method for fracturing a subterranean formation, the method comprising injecting a fracturing fluid into a wellbore through the subterranean formation, thereby creating a fracture network in the subterranean formation, the fracturing fluid comprising a proppant and a plurality of polymer fibers having a deflection temperature ranging from about 70° C. to about 150° C. dispersed in a carrier fluid.

Abstract: A method to improve fluid flow in a hydraulic fracture from a subterranean formation which includes the steps of (1) formulating a slurry which comprises (a) proppant particles, (b) a carrier fluid, and (c) low density particles, wherein the fluid is capable of undergoing a transformation to cause an agglomeration of two or more proppant particles and/or low density particles; and (2) injecting the slurry into the formation; and (3) the agglomeration of the proppant particles and/or low density particles, is provided.
