Slickwater is water with a limited amount of sand, friction reducers and other chemical additives to improve the efficiency of hydraulic fracturing. It works well in shale gas reservoirs because ts low viscosity allows the fracturing fluid to leak slowly out of the hydraulic fracture into many small, naturally-occurring fractures in the shale. During the process of hydraulic fracturing, slickwater can be pumped down the wellbore as fast as 100 bbl/min. to fracture the shale -- as opposed to the typical 60 bbl/min. rate of typical fracturing fluids[1] Slickwater is typically used in highly-pressurized, deeper shales, while fracturing fluids using nitrogen foam are more common in shallower shales and those that have lower reservoir pressure.[2]
