What is Frac Sand? A Durable Sand for Hydraulic Fracturing

What Is Frac Sand? "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 ...
