Biocides in Hydraulic Fracturing Fluids: A Critical Review ...
Biocides in Hydraulic Fracturing Fluids: A Critical Review ...

Biocides are critical components of hydraulic ,fracturing, (“fracking”) fluids used for unconventional shale gas development. Bacteria may cause bioclogging and inhibit gas extraction, produce toxic hydrogen sulfide, and induce corrosion leading to downhole equipment failure. The use of biocides such as glutaraldehyde and quaternary ammonium compounds has spurred a public concern and debate ...
