    摘要： The method disclosed herein includes the introduction of proppant-free stage and a proppant laden stage into the wellbore and/or subterranean formation. The method increases the effective fracture width and enhances fracture conductivity within the formation. Either the proppant-free stage or the proppant laden stage contains a breaker. At least one of the proppant-free stage or proppant laden stage contains a viscosifying agent to which the breaker has affinity. The viscosifying agent may be a superabsorbent, a viscosifying polymer (other than a superabsorbent) or a viscoelastic surfactant. The breaker has greater affinity for the viscosifying agent not present in the same stage as the breaker. Either the proppant-free stage or the proppant laden stage may be foamed.

    摘要： Disclosed herein is a foamed fracturing fluid comprising a carrier fluid; a polymer that is soluble in the carrier fluid; the polymer being a synthetic polymer, wherein the synthetic polymer comprises a labile group that is operative to facilitate decomposition of the synthetic polymer upon activation of the labile group; a foaming agent; and a gas constituent, the synthetic polymer, foaming agent and gas constituent being operative to increase the viscosity of the carrier fluid to about 50 centipoise or greater at 100 s−1, the foamed fracturing fluid being operative to reduce friction during a downhole fracturing operation and to transport a proppant during the downhole fracturing operation. A method for treating a hydrocarbon-bearing formation is also disclosed herein.
