The Ordovician St. Peter Sandstone in the Midwest is a primary source of silica sand for many end uses and is a major source of frac sand as well. Mined in five States, frac sand from the St. Peter Sandstone is within reasonable transport distance to numerous underground shale formations producing natural gas.
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays. The resource is also used in industrial processing to make everyday
