Barnett Shale

wells drilled through the shale formation. Hydraulic fracturing works by creating fractures in the rock formation that stimulate the flow of natural gas. Wells are drilled vertically hundreds to thousands of feet below the land surface and include horizontal or directional sections extending thousands of feet. Fractures are created by pumping large quantities of fluids at high pressure…

Sullivan, Susquehanna, and Tioga County, Pennsylvania. The Lock Haven Formation underlies the Catskill Formation composed of primarily of gray to red sandstone and overlies the Brallier Formation composed of olive gray to dark thick laminated marine shale. Also the Lock Haven Formation is composed of Devonian aged (480 million years old)…

Natural gas drilling is becoming a major profit maker for a multitude of companies. In response to being offered one hundred thousand dollars to sell his land for hydraulic fracturing, Josh Fox, a native Pennsylvania documentary filmmaker, begins to do his own research into the drilling industry. With the help of people from across the county, Fox is able to obtain first hand repercussions of the natural gas drilling on water supplies, overall health, animals, life after fracking, and the lack…

"Economic and environmental aspects of Fracking - Fracking is an economically beneficial and essential process for oil companies. Fracking is a process of drilling and injecting fluid into ground at a high pressure to fracture shale rocks to release Hydrocarbons, but it has raised certain environmental concerns that that have burdened oil companies to overlook at the processes they are using to extract hydrocarbons. Certain concerns about Fracking are: Hydraulic fracking is quenching the water…

Hydraulic fracturing, also known as fracking, is the process of drilling and injecting fluid into the earth’s surface at high pressures in order to fracture the clastic sedimentary rock or shale rock surface. Fracturing the shale rock releases the natural gas, petroleum, or water that could be trapped inside these underground natural reservoirs. The wells are drilled vertically into the earth’s surface for hundreds or thousands of feet and include horizontal or directional extensions to allow…

safer ways to complete the process. Toxicological Science can lessen the casualties of or effects to human health and the environment, but only by furthering the science and technology of it. “Advances in the technology of hydraulic fracturing of shale to produce natural gas and oil offers the United States welcome opportunities to enhance domestic energy options and promote energy independence” (Goldstein 1). The research gathered from Toxicological science shows and characterizes the chances…

of drilling that gas been used commercially for 65 years. Fracking is so dangerous and it has created very serious circumstances. Chemical used in fracking are toxic. According to nature international journal of science (2011) Extracting gas from shale increases the visibility of this resource. But the health and environment risks may be too high. There are approximately 8 most dangerous side effects of fracking that the industry doesn’t want us to heat about. 40,000 gallons (1 US gallon # 3.75…

Hydraulic fracturing started as an experiment in 1947 by Floyd Farris. The success of fracking caused it to be used worldwide to create new oil and gas wells. Fracking is used differently in each state, depending on the sentiment for example, the Barnett shale…

It became commercially practicable to extract natural gas from shale when Mitchell Energy developed a technique known as slickwater fracturing. The process of slickwater fracturing begins by drilling a vertical well to the natural gas layer. Next, they drill up to 10,000 feet horizontally. Finally, a water and chemical…

earth’s crust and injecting water, sand and chemicals under immense pressure in order to obtain natural gas. With this process there are benefits and also disadvantages. There are many risks to groundwater from surface spills that are associated with shale energy development, they can be managed or mitigated by following certain precautions and steps. Groundwater is present throughout the atmosphere. There is surface water, atmospheric water and groundwater. It is something both humans and…
