Hydraulic fracturing, (fracking) is a process used to recover commercial quantities of oil and gas from low permeability unconventional reservoirs such as shale. Pressurised ,fluid,, usually consisting of water, chemical additives, and a proppant (e.g., sand) is injected via a borehole into low permeability rock to induce hydraulic fractures.
