What is more important, the cost of oil and gas, or the health of the human race? Horizontal Hydraulic Fracturing, more commonly known as “fracking” remains a relatively uncommon drilling technology. There was only one in fourteen wells drilled in the United States and Canada horizontally in 2002 (Gold). In 2012, six of every ten wells were horizontal. It is a process in which sand, water, and chemicals are used to blast open shale rock to release the gases that are trapped inside. After the vertical

on the Environment and Public Health People are now recognizing some serious concerns to the public health and the drinking water becoming contaminated, because the fracturing of shale in our communities and what can be done to stop it all. The hydraulic fracturing of shale needs to be, banned until further investigations are completed to determine how safe it is to people and the environment surrounding the drilling site. It all started with a few cases of illness, which everyone assumed was a virus

Hydraulic fracturing, otherwise known as “fracking,” by definition, means the process of drilling and injecting fluid into the ground thousands of feet deep, at a high pressure; in order to fracture shale rocks to release the natural gases inside (Schrope n.d.). A more adequate explanation on to why we perform the method of “fracking” is that it is an easier process to obtain the natural gases inside the rocks. These natural gases are used for many sources of energy throughout the world. Natural

development of hydraulic fracturing regulation saw significant changes in the late 20th century. There had been state regulations throughout the 1940’s, but these were mostly concerned with surface water contamination. By the 1950s, however, landowners were complaining of contamination of drinking water, and state oil agencies discovered contaminated acquifers in the 1960’s. These complaints and the subsequent lawsuits in the 1960’s led to the beginning of state regulations on hydraulic fracturing.

Hydraulic fracturing -- otherwise known as fracking -- is a process which allows us to retrieve oil and natural gas from shale. The process consists of a mixture of water and sand -- with the addition of a few chemicals to help carry the sand, keep bacteria from forming, and for lubrication -- being pumped down the wellbore and into the deep underground reservoir formations. The wellbore is the hole drilled beforehand, implemented with steel casing vertically and horizontally, creating the well.

Hydraulic fracturing, or fracking, is a well stimulation process used to obtain natural resources from underground geological formations. Although used in several different applications, including the extraction of oil and geothermal energy, hydraulic fracturing in natural gas production from shale formations has recently taken center stage. It is estimated that shale gas will comprise over 20% of the total U.S. gas supply by 2020 (Energy Information Administration, 2009). As hydraulic fracturing
