DetailsHydraulic fracturing, or fracking, is the procedure of creating fractures in shale, coalbed and tight-sand formations by injecting fluid (such as water, oil, or propane) into cracks to force them further open. This enlarges fissures which allow more oil and gas (methane) to flow out of the rock and
DetailsSand is critical to fracking. After workers drill down into rock, they create fractures by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand.
