The Truth About Fracking



Fracking, a new and interesting way to drill for oil, will it have devastating effects on the environment?

What is Hydraulic Fracturing? Geologists have known for a long time that deposits of oil are trapped in “shale reservoirs” but recently fracking fluid has made it possible to extract trapped oil.

The first step is to drill 10,000 feet below the surface while installing metal casing and cement. After drilling vertically, it turns and drills horizontally till reaching the destination, at this point the drilling rig is removed.

In the next step, a “perforating gun” is installed at the end of the pipe. This gun is equipped with shaped explosive charges. When the gun is fired it creates holes in the pipe, the cement, and into the rock. After the gun is removed, the fracking mixture is pumped into the pipe. The mixture contains water, sand, and chemicals.

They take many steps to keep the environment clean; drillers drill 10000 feet below the surface (far below any water source at 900 feet.)

Secondly, they install still pipes with cement to prevent any leakage of the fracking fluid. With Fracking only one drilling pad is necessary to drill many wells. This helps save the surface environment (more than any other method could). 15 to 50 percent of all the fracturing fluid is removed and disposed of according to government regulations. This is the process that is considered to be environmentally unfriendly.
