GNatural gas plays a key role in our nation’s clean energy future. it can use to drill about 500 feet under the ground. The U.S. has vast reserves of natural gas that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies enabling greater access to gas in shale formations. Responsible development of America’s shale gas resources offers important economic, energy security, and environmental benefits.

Slick water hydraulic fracturing, also known as hydrofracking, is a new development in natural gas extraction. The process was created by Halliburton Inc. (well known for its work in Iraq and elsewhere), Schlumberger Inc., and Messina Inc. This process makes mining for natural gas in dense shale more economically possible, where before it was not.

Slick water hydrofracking is different from conventional natural gas drilling in a couple of ways.

First, slick water hydrofracking uses significantly more water than conventional drilling, as well as a “slick water” mixture that is pumped into the shale to fracture the rock and release the gas. Second, there is an increased potential for toxicity and its long-term impacts. Finally, there is the environmental impacts of the drilling: surface and subterranean damage including forestland loss, multiple well sites, groundwater and surface water contamination, habitat and species disturbance, and likely an increased number of access roads to the well sites.
