Hydraulic ,fracturing, (HF) is a well stimulation process used to maximize the extraction of underground resources – oil, natural gas and geothermal energy. The HF process includes the acquisition of water/mixing of chemicals, production zone ,fracturing,, and HF ,flowback, disposal. In the United States, HF has been used since the 1940’s.

Flowback refers to fluid returning to the surface after hydraulic fracturing has occurred, but before the well is placed into production. After the well has been placed into production, the fluid returned to the surface is called produced water. Collectively, these fluids are termed hydraulic fracturing wastewater.
