Hydraulic fracturing is a technique in which water is mixed with sand

Hydraulic fracturing is a technique in which water is mixed with sand or ceramic proppants and chemicals to make the “fracturing fluid” which is injected at high pressure into a wellbore to create fractures in a hydrocarbon formation. The fractures, supported by proppants, act as conduits along which fluids such as gas and oil can migrate to the wellbore and then up to the surface.
The two main purposes of fracturing fluid are 1) to extend fractures while under high pressure and 2) to carry proppant into the formation and leave it there without damaging the formation or production of the well.
