Slickwater

From Wikimarcellus

Slickwater or slick water fracturing is a method of hydro-fracturing which reportedly involves injecting friction reducers, biocides, surfactants and scale inhibitors. For example methanol and naphthalene can be used for biocides. Hydrochloric acid and ethylene glycol may be utilized as scale inhibitors. Butanol and ethylene glycol monobutyl ether (2-BE) are used in surfactants. It typically uses more water than earlier fracturing methods--between one and five million gallons per fracing operation.
