FRACTURING FLUIDS COMPRISING FIBERS TREATED WITH CROSSLINKABLE, HYDRATABLE POLYMERS AND RELATED METHODS

摘要

A low-polymer-load fracturing fluid may include an aqueous carrier fluid, proppant, and polymer-treated degradable fibers. The polymer-treated degradable fibers may include degradable fibers that have been at least partially treated with a crosslinkable, hydratable polymer. In some instances, a method may involve placing a low-polymer-load fracturing fluid having an initial viscosity into a subterranean formation penetrated by a wellbore at a rate to generate pressure above fracture gradient to form or enhance at least one fracture in the formation matrix surrounding a designated portion of the wellbore; placing the low-polymer-load fracturing fluid into the fracture and allowing the polymer to crosslink and increase the initial viscosity to a gelled viscosity; and allowing the polymer-treated degradable fibers to degrade and reduce the gelled viscosity to a broken viscosity.
