  • USE OF PERACETIC ACID/HYDROGEN PEROXIDE AND PEROXIDE-REDUCING AGENTS FOR TREATMENT OF DRILLING FLUIDS, FRAC FLUIDS, FLOWBACK WATER AND DISPOSAL WATER
    Publication number: 20130264059
    Abstract: Methods for the use of peracid compositions having decreased hydrogen peroxide concentration and a UV-blocking agent for various water treatments, including oil- and gas-field operations, and/or other aseptic treatments are disclosed. In numerous aspects, peracetic acid is the preferred peracid and is treated with a peroxide-reducing agent to substantially reduce the hydrogen peroxide content.

  • USE OF PERACETIC ACID/HYDROGEN PEROXIDE AND PEROXIDE-REDUCING ENZYMES FOR TREATMENT OF DRILLING FLUIDS, FRAC FLUIDS, FLOWBACK WATER AND DISPOSAL WATER
    Publication number: 20130259743
    Abstract: Compositions and methods for the use of peracid compositions having low to substantially no hydrogen peroxide for various water treatments, including oil- and gas-field operations, and/or other aseptic treatments are disclosed. In numerous aspects, peracetic acid is the preferred peracid and is treated with a peroxide-reducing agent to substantially reduce the hydrogen peroxide content.
