摘要： Emulsion or microemulsion for treating an oil or gas well having a wellbore are provided, and related methods. In some embodiments, the emulsion or microemulsion comprises an aqueous phase; a surfactant; and a non-aqueous phase comprising a first type of solvent and a second type of solvent. In some embodiments, the first type of solvent is a long chain hydrocarbon. In some embodiments, the second type of solvent is an oxygenated solvent. The emulsion or microemulsion may comprise additional components (e.g., at least one type of co-solvent).

摘要： An oxidative breaker system for use in reducing the viscosity of a polysaccharide-based or derivatized polysaccharide-based suspension includes a silicone carrier fluid, an oxidizer, and a suspension aid. The suspension aid is preferably fumed silica. The oxidizer may be selected from the group consisting of alkali metal peroxide, transition metal peroxide, persulfate compound, bromide compound, and bromate compound. In highly preferred embodiments, the oxidizer is magnesium peroxide or calcium peroxide. Alternative carrier fluids and suspension agents are also included in the art. Also disclosed is a method for breaking a polysaccharide-based suspension with the inventive oxidative breaker system.

摘要： A well treatment additive includes a siloxane surfactant, a solvent and an aqueous phase. The solvent is preferably a terpene hydrocarbon. Also disclosed is a method for using the well treatment additive to form and enhance the properties of terpene solvent based additives useful for the treatment of oil and gas wells. Methods of using the novel well treatment additives include using the additives in a variety of well treatment processes including, but not limited to, acidizing operations, hydraulic fracturing operations, well remediation operations and water removal operations.
