Abstract: A method of treating wastewater resulting from hydrocarbon production operations is provided, for repurposing as a disinfectant. The method includes a) providing wastewater resulting from hydrocarbon production operations containing greater than 3 ppm bromide ion; and b) adding a sufficient amount of an oxidizing agent to convert the bromide ion to hypobromous acid used in the formation of a disinfectant solution. At least one of chloramine, bromamine, and hypobromous acid is present in the disinfectant solution to provide disinfecting properties. A source of ammonia may also be added to the wastewater, and the disinfectant solution may be blended with other water to provide blended water for use as a fracturing fluid.

Abstract: Novel formulations containing a non-oxidative biocide, such as DBNPA, and a source of an in situ produced active biocide, such as a concentrated aqueous solution of an inorganic halide salt, are disclosed. These novel formulations are particularly effective in the treatment of water, and are characterized by high stability, desirable rheological properties and an excellent biocidal activity.

Abstract: A method of reusing waste-water resulting from hydrocarbon production operations as a disinfectant. The method includes a) providing waste-water resulting from hydrocarbon production operations containing greater than 3 ppm bromide ion; b) adjusting the pH of the waste-water to a pH that renders the fracturing fluid non-scaling, while maximizing the production of hypobromous acid and c) adding a sufficient amount of an oxidizing agent to convert the bromide ion to hypobromous acid to provide a disinfectant solution.
