Frequently Asked Questions
- icon Composition: Sand usually contains many different rock types; however, silica sand consists of nearly 95% quartz.
- icon Strength: Quartz is a very hard mineral and able to withstand high pressures produced during the hydraulic fracturing process without breaking.
- icon Shape: The sand grains are shaped like little ball bearings allowing for oil and gas to flow between individual grains without clogging the fractured rock. It is very important that the round, unbroken grain shape is preserved throughout mining, processing, and transportation.
- icon Size: The sand grains are fairly uniform in size. When washed and screened, the sands meet a precise grain-size distribution required for frac sand
