In one aspect, the present technology provides polycationic quaternary ammonium compounds that comprise bis-quaternary compound. The bis-quaternary compounds of the present technology can be symmetric or dissymmetric. In another aspect, the present technology provides viscoelastic well bore treatment fluids comprising water, and at least one polycationic quaternary ammonium compound that comprises a bis-quaternary compound. In another aspect, the present technology provides polycationic carboxylates. Preferred viscoelastic compositions of the present technology maintain viscoelasticity at a temperature greater than about 80° C, preferably greater than about 100° C or 110° C when the amount of the one or polycationic quaternary compounds is less than about 10% by weight based on the total weight of the composition.

摘要： Provided are treatment fluids that comprise an aqueous base fluid, an acid, and a methyl ester sulfonate surfactant, and associated methods of use. In one embodiment, the present invention provides a method of acidizing a subterranean formation comprising: providing a treatment fluid comprising an aqueous base fluid, an acid, and a methyl ester sulfonate surfactant; introducing the treatment fluid into a well bore that penetrates the subterranean formation; and allowing at least a portion of the treatment fluid to react with at least a portion of the subterranean formation so that at least one void is formed in the subterranean formation. In some instances, the treatment fluids exhibit viscoelastic behavior which may be due, at least in part, to the association of at least a portion of the methyl ester sulfonate surfactant into a plurality of micellar structures.

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.

摘要： Embodiments of the Present Invention relate to a reversibly thickenable non-polymeric fluid that has low viscosity in strong acid, gels when the acid concentration is reduced by only a small amount, and is subsequently decomposed by the acid. In particular it relates to an aqueous mixture of zwitterionic surfactants, inorganic acids, and organic acids Most particularly it relates to the use of this fluid as a diverting agent for easily-damaged sandstones, for example prior to matrix acidizing.

摘要： Viscoelastic surfactant based aqueous fluid systems useful as thickening agents in various applications, e.g. to suspend particles produced during the excavation of geologic formations. The surfactants are zwitterionic/amphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylamino mono- or di-propionates derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water-soluble salt or organic additive such as phthalic acid, salicylic acid or their salts.
