Hydraulic ,fracturing, is ,fracturing, of stone by pressurization. This procedure by which oil and natural gas can be forced from the Earth. The hydraulic ,fracturing, procedure takes 1000000s of gallons of clean H2O. sand. chemicals and pumps them underground at high force per unit area to interrupt isolated stone to let go of gas and or oil.
