A well is fracked by sand, water and lube that is sent into the well under high pressure to release gas from the gas formations in the ground, explains Shale Stuff. Fracking horizontal wells increases production as much as 20 times more than a vertical well, according to Rig Zone.
To frack a gas well, the hole must first be drilled, encased with surface casing and surrounded with cement to prevent ground and water contamination. Then, a perforating gun is used to put holes in the casing in the horizontal section of a well. After the perforating gun is removed, the well is fracked to release the gas.
Fracking is used for horizontal wells and not for vertical wells. A horizontal well is drilled vertically until the desired depth is reached, also known as a kick off point. Then, a curve is drilled from this kick off point until the well reaches 90 degrees, and then the horizontal portion of the well is drilled. Once the well is fully drilled, a temporary well head is installed into the ground until the fracking process begins. After the fracking process is completed, a permanent well head is installed, states Shale Stuff.
Energy From Shale, a website of the American Petroleum Institute, claims that the fracking industry supplies jobs to many Americans. An estimated 2.1 million jobs were a result of the industry in 2012, and the industry provided lower energy costs to U.S. households in 2012 as a result of the fracking and energy boom.
