Frac sand is the key ingredient in the hydraulic fracturing process, in which oil and gas drillers pump frac sand and other materials into wells to break up shale rock, through which natural gas and petroleum will flow more easily. So easily, it has helped propel the US towards energy independance and insultation from global volitality. What’s helped drill that home is the process known as fracking. So shale to the king, baby. On today’s freight all kind we’re talking frac sand.
