摘要： A breaker composition for use in a fracturing fluid comprises water, at least one peroxide (e.g., tert-butyl hydroperoxide), and optionally at least one alcohol (e.g., propylene glycol and/or a butyl alcohol). The peroxide(s) and optional alcohol(s) are present in amounts effective to reduce the viscosity of a fracturing fluid at a temperature of 90-300 F. (the “breaking temperature”), and to prevent rehealing of the fracturing fluid, i.e., to maintain the reduced viscosity for a period of time after the temperature is reduced from the breaking temperature to a temperature below the breaking temperature (e.g., after the temperature is reduced from the breaking temperature to room temperature).

摘要： The addition of at least one promoter selected from the group consisting of thiosulfate salts, sulfite salts, bisulfite salts, erythorbate salts, isoascorbate salts, and combinations thereof to an aqueous treatment fluid containing a viscosifying polymer and a peroxide helps to promote the activity of the peroxide as a breaker, thus facilitating a reduction in viscosity of the aqueous treatment fluid at lower temperatures than are possible in the absence of the promoter. The promoted aqueous treatment fluid is useful as a fracture fluid to fracture subterranean formations in oil and gas recovery.

摘要： Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).

摘要： A breaker composition for use in a fracturing fluid comprises at least one organic peroxide (e.g., tert-butyl hydroperoxide), at least one dye (e.g., an FD&C dye), and at least one alcohol (e.g., propylene glycol). A promoter composition for use in a fracturing fluid comprises at least one promoter (e.g., sodium thiosulfate), at least one dye (e.g., an FD&C dye). According to certain embodiments, the dye increases the efficiency of the promoter and/or the organic peroxide, so that the break time and the peak viscosity of the aqueous treatment fluid are reduced.

摘要： The present invention relates to an improved modified polyamide having increased molecular weight and substantially the same or marginally increased viscosity versus shear weight as the unmodified polyamide. A method for modifying polyamides to provide these improved properties also is disclosed wherein a polyamide having an initial molecular weight is contacted with at least one organic peroxide, at least one coagent and/or one free-radical trap to form an improved polyamide having an increased molecular weight and substantially the same viscosity versus shear rate. The present disclosure also relates to polyamide compositions comprising organic peroxides and articles made from the modified polyamide.
