Induced Hydraulic Fracturing Hydrofracturing Poster

Author: Mikenorton. Induced hydraulic fracturing (hydrofracturing, also commonly known as fracking or fraccing) is a mining technique in which a liquid (in most cases water) is mixed with sand and chemicals and the resultant mixture injected at high pressure into a wellbore. This creates small fractures in the deep rock formations, typically less than 1mm wide, along which gas, petroleum and brine may migrate to the well. Hydraulic pressure is removed from the well, then small grains of proppant (sand or aluminium oxide) hold these fractures open once the rock achieves equilibrium.
