Hydraulic ,fracturing, or “fracking” injects a mixture of ,water,, sand and chemicals under high pressure into dense shale rock formations to crack the rock and release natural ,gas,. Conventional fracking has been around for decades, but the techniques, technologies and chemicals used to reach new, remote ,gas, reserves are far more intensive and risky than conventional ,gas, drilling.
