  • Colored organic peroxide compositions and methods for breaking fluids
    Patent number: 10787604
    Abstract: 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.
    Type: Grant

  • Colored organic peroxide compositions
    Patent number: 10358559
    Abstract: Stable organic peroxide compositions include 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, tert-butanol, and/or glycerin).

  • Compositions and methods for breaking hydraulic fracturing fluids
    Patent number: 10294414
    Abstract: 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).
