    摘要: Methods of fracturing a subterranean formation containing a hydrocarbon include introducing a first fracturing fluid that includes natural gas into the formation at a rate and pressure sufficient to create a complex fracture in the formation; introducing a second fracturing fluid into the formation, wherein the second fracturing fluid comprises water, a gelling agent, a foaming agent, natural gas, and proppant particulates; and allowing the second fracturing fluid to transport a portion of the proppant particulates into the complex fracture.

    摘要: Methods of treating a subterranean formation. A pad fluid is introduced into a wellbore penetrating the subterranean formation to create or enhance one or more fractures in the subterranean formation. A fracturing fluid is introduced into the wellbore. The fracturing fluid includes a polymer having a hydrophobic monomer and a hydrophilic monomer. The fracturing fluid further includes a proppant and a second aqueous base fluid. The fracturing fluid does not include a crosslinker or an oxidative breaker. The fracturing fluid is broken thereby settling the proppant in the fracture.
