Which type of gas is obtained by the controversial process of hydraulic fracturing or 'fracking'?
Hydraulic fracturing and radionuclides water, this doesn't always happen. Radioactive tracers are not yet listed on FracFocus, a website indicating chemical composition of fracking fluid of individual wells, but federal and state nuclear regulatory agencies keep records of their use. Hydraulic fracturing and radionuclides Hydraulic fracturing is the propagation of fractures in a rock layer by pressurized fluid. Induced hydraulic fracturing or hydrofracking, commonly known as fracking, is a technique used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction. Radionuclides are associated with hydraulic fracturing in two main ways. Injection of man-made radioactive
Hydraulic fracturing Hydraulic fracturing Hydraulic fracturing (also fracking, fraccing, frac'ing, hydrofracturing or hydrofracking) is a well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open. Hydraulic fracturing began as an experiment in
