What is Frac Sand? A Crush-Resistant Sand for Oil and Gas Wells
"Frac sand" is a high-purity
quartz sand with very durable and very round grains. It is a crush-resistant material produced for use by the petroleum industry. It is used in the
hydraulic fracturing process (known as "fracking") to produce petroleum fluids, such as oil, natural gas and natural gas liquids from rock units that lack adequate pore space for these fluids to flow to a well. Most frac sand is a natural material made from high purity
sandstone. An alternative product is ceramic beads made from sintered
bauxite or small metal beads made from aluminum
