    摘要: Internal breakers are given that break fluids viscosified with non-polymeric viscosifiers such as viscoelastic surfactants, inside formation pores. The breakers are polyols, for example natural and synthetic sugars, monoalcohols, and mixtures of the two. The sugars may be ketones and aldehydes. The sugars are also breaker aides for oxidizing agents used as breakers. Methods of using the breakers and breaker aides in oilfield treatment fluids are given.

    摘要: A method of decreasing the viscosity of a gelled organic-based fluid is disclosed. The method comprises combining an organic solvent, a gelling agent, and a metal crosslinker; forming the gelled organic-based fluid; and adding a chelating agent forming a complex with the metal to decrease the viscosity of the gelled organic-based fluid. The chelating agent may be chosen within nitrilotriacetic acid (NTA), citric acid; ascorbic acid, hydroxyethylethylenediaminetriacetic acid (HEDTA) or its salts, ethylenediaminetetraacetic acid (EDTA) or its salts, diethylenetriaminepentaacetic acid (DTPA) or its salts, phosphinopolyacrylate, thioglycolates, or a combination thereof.

    摘要: Disclosed are methods of treating subterranean formations with rapidly hydratable treatment fluids based upon heteropolysaccharides. In particular, the invention relates to treatment methods with fluids containing a heteropolysaccharide, aqueous medium, and an electrolyte, wherein the fluids may further include a gas component, a surfactant and/or an organoamino compound. The fluids exhibit good rheological properties at elevated temperatures, and unusually rapid hydration rates which allows utilizing such fluids without the need of hydration tanks.
