    Hydraulic fracturing‚ as known as fracking‚ is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside (Dong). According to many recent research studies fracking is very harmful to the environment and shouldn’t be done here in Coppell‚ but how so? You need to understand the fracturing fluid that is used for fracking. The fluid from the hydraulic fracturing process is nearly 99.5% water and sand‚ which makes

    say it’s not the extraction of oil or gas that is causing the earthquakes. It’s when waste fracking fluid is injected back into earth that they believe lubricates faults‚ causing tectonic plates to slip more easily. As the number of franking increase in Oklahoma so do the numbers of earthquakes. It has become so severe that it sky rocketed from being a dozen in 2008 to over a thousand in 2010. As franking causes earthquakes from putting fluids into the earth‚ groundwater extraction can also cause an
