Fracking is big in Texas. I saw the documentary GasLand and that is about the first time that I learned about fracking. I had seen some stories about problems here in Texas with fracking and with the corporations refusing to tell about the stuff they were pumping into the ground. There was also reports of it being done next to schools and parks. So little pipes were sticking up from the ground and no one knew there were even there.
But I learned a lot from the GasLand documentary. Now I am not a Republican so I don’t take anything I see as fact until I hear other points of view and do some research on my own.
I guess the right and the fracking people are going to put out their own documentary called FrackNation soon.
“Hydraulic fracturing is the propagation of fractures in a rock layer caused by the presence of a pressurized fluid. Hydraulic fractures form naturally, as in the case of veins or dikes, and is one means by which gas and petroleum from source rocks may migrate to reservoir rocks.
However oil and gas companies may attempt to accelerate this process in order to release petroleum, natural gas, coal seam gas, or other substances for extraction, where the technique is often called fracking[a] or hydrofracking.[1] This type of fracturing, known colloquially as a frack job (or frac job),[2][3] is done from a wellbore drilled into reservoir rock formations. The energy from the injection of a highly-pressurized fracking fluid[4] creates new channels in the rock which can increase the extraction rates and ultimate recovery of fossil fuels. When done in already highly-permeable reservoirs such as sandstone-based wells, the technique is known as well stimulation. Operators typically try to maintain fracture width or slow its decline following treatment by introducing aproppant[5] into the injected fluid, a material, such as grains of sand, ceramic, or other particulates, that prevent the fractures from closing when the injection is stopped. Consideration of proppant strengths and prevention of proppant failure becomes more important at deeper depths where pressure and stresses on fractures are higher.
Distinction can be made between low-volume hydraulic fracturing used to stimulate high-permeability reservoirs, which may consume typically 20,000 to 80,000 gallons of fluid per well, with high-volume hydraulic fracturing, used in the completion of tight gas and shale gas wells; high-volume hydraulic fracturing can use as much as two to three million gallons of fluid per well.[6] This latter practice has come under scrutiny internationally due to concerns about theenvironmental impact, health and safety, and has been suspended or banned in some countries.[7]…”
