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.
