  • Breaking a fracturing fluid to prop a fracture in a subterranean formation
    Patent number: 11236266
    Abstract: 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.
    Type: Grant
