FLUIDO TENSOATIVO VISCOELÁSTICO MULTICOMPONENTE E MÉTODO DE UTILIZAÇÃO COMO UM FLUIDO DE FRATURAMENTO |
摘要 |
There is a viscoelastic fluid. The fluid has one or more cationic surfactants selected from the group consisting of certain quaternary salts, certain amines, and combinations thereof; one or more anionic polymers/anionic surfactants; one or more of certain zwitterionic/amphoteric surfactants; and water. There is also a method of fracturing a subterranean formation. The viscoelastic fluid is pumped through a wellbore and into a subterranean formation at a pressure sufficient to fracture the formation. There is also a method for gravel packing a subterranean formation. |
