Abstract:
A system and method of treating a fluid to be used for hydraulic fracturing adds an effective amount of chlorine dioxide to the fluid to act as a biocide that kills harmful bacteria. A system for adding chlorine dioxide to the fluid can continuously add chlorine dioxide to an incoming flow of the fluid to produce a continuous flow of treated fluid.

Claim (Index 1):
A method of treating a fluid used for hydraulic fracturing, comprising:\n obtaining chlorine dioxide; adding an amount of the obtained chlorine dioxide to a continuously supplied fluid which is to be used for hydraulic fracturing such that the chlorine dioxide acts as a biocide, wherein a prescribed amount of the chlorine dioxide is added per unit volume of the continuously supplied fluid; periodically testing the continuously supplied fluid after the chlorine dioxide has been added and after at least some of the chlorine dioxide has been consumed in reactions with bacteria and/or biological contaminants that were originally present in the fluid to determine a concentration of the chlorine dioxide in the supplied fluid; and selectively adjusting the prescribed amount of chlorine dioxide that is added per unit volume of the continuously supplied fluid based on the result of the testing step such that a residual concentration of chlorine dioxide remaining in the fluid after the chlorine dioxide has had an opportunity to react with bacteria and/or biological contaminants is in the range of 0.1 to 25 parts per million.
