Two Pennsylvania children have been banned from talking about shale gas drilling, or fracking, for what appears to be the rest of their lives by the terms of a legal settlement reached between their parents, Chris and Stephanie Hallowich, and three oil and gas companies who lead drilling operations at the state’s Marcellus Shale.
Hydraulic fracturing is the fracturing of rock by a pressurized liquid. Some hydraulic fractures form naturally—certain veins or dikes are examples. Induced hydraulic fracturing or hydrofracturing, commonly known as fracking, is a technique in which typically water is mixed with sand and chemicals, and the mixture is injected at high pressure into a wellbore to create small fractures (typically less than 1mm), along which fluids such as gas, petroleum, uranium, and brine water may migrate to the well. The radial distance of influence of the process from the well bore is typically 150 yards. 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. The technique is very common in wells for shale gas, tight gas, tight oil, and coal seam gas and hard rock wells. This well stimulation is only conducted once in the life of the well and greatly enhances fluid removal and well productivity. A different technique where only acid is injected is referred to as acidizing.
