A New Approach to Biocide Application Provides Improved Efficiency in Fracturing Fluids

Hydraulic fracturing of oil and gas wells requires high volumes of water. Often these waters originate from rivers, lakes, ponds, and recovered water from previous fracturing treatments. The waters are often infested with aerobic and anaerobic bacteria that can cause multiple problems. The include degradation of fracturing chemicals, down-hole corrosion, biological-based H2S generation, and down-hole flow-impairment due to slime producing bacteria.
