Fracking

Fracking

Hydraulic 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 into the wellbore. From there, the oil and gas can be extracted.
