What is fracking and why is it controversial?

Members of Congress, gas companies, news organization, drilling opponents: They've all made bold claims about hydraulic fracturing fracking and the U. We take on 10 controversial quotes about natural gas and set the record straight. Less than a decade ago, industry analysts and government officials fretted that the United States was in danger of running out of gas. No more. Over the past several years, vast caches of natural gas trapped in deeply buried rock have been made accessible by advances in two key technologies: horizontal drilling, which allows vertical wells to turn and snake more than a mile sideways through the earth, and hydraulic fracturing, or fracking.

Developed more than 60 years ago, fracking involves pumping millions of gallons of chemically treated water into deep shale formations at pressures of pounds per square inch or more. This fluid cracks the shale or widens existing cracks, freeing hydrocarbons to flow toward the well. These advances have led to an eightfold increase in shale gas production over the past decade. According to the Energy Information Administration, shale gas will account for nearly half of the natural gas produced in the U.

But the bonanza is not without controversy, and nowhere, perhaps, has the dispute over fracking grown more heated than in the vicinity of the Marcellus Shale. According to Terry Engelder, a professor of geosciences at Penn State, the vast formation sprawling primarily beneath West Virginia, Pennsylvania and New York could produce an estimated trillion cubic feet of gas over its to year life span. That's nowhere close to Saudi Arabia's total energy reserves, but it is enough to power every natural gas—burning device in the country for more than 20 years.

The debate over the Marcellus Shale will shape national energy policy—including how fully, and at what cost, we exploit this vast resource. There is no question that hydraulic fracturing uses a lot of water: It can take up to 7 million gallons to frack a single well, and at least 30 percent of that water is lost forever, after being trapped deep in the shale.

And while there is some evidence that fracking has contributed to the depletion of water supplies in drought-stricken Texas, a study by Carnegie Mellon University indicates the Marcellus region has plenty of water and, in most cases, an adequate system to regulate its usage. The amount of water required to drill all of the Marcellus wells permitted in Pennsylvania in the first 11 months of would equal the amount of drinking water used by just one city, Pittsburgh, during the same period, says environmental engineering professor Jeanne VanBriesen, the study's lead author.

Plus, she notes, water withdrawals of this new industry are taking the place of water once used by industries, like steel manufacturing, that the state has lost. Burning natural gas is cleaner than oil or gasoline, and it emits half as much carbon dioxide, less than one-third the nitrogen oxides, and 1 percent as much sulfur oxides as coal combustion. But not all shale gas makes it to the fuel tank or power plant. The methane that escapes during the drilling process, and later as the fuel is shipped via pipelines, is a significant greenhouse gas. At least one scientist, Robert Howarth at Cornell University, has calculated that methane losses could be as high as 8 percent. Industry officials concede that they could be losing anywhere between 1 and 3 percent.

Some of those leaks can be prevented by aggressively sealing condensers, pipelines and wellheads. But there's another upstream factor to consider: Drilling is an energy-intensive business. It relies on diesel engines and generators running around the clock to power rigs, and heavy trucks making hundreds of trips to drill sites before a well is completed. Those in the industry say there's a solution at hand to lower emissions—using natural gas itself to power the process. So far, however, few companies have done that. The senator is incorrect. In the past two years alone, a series of surface spills, including two blowouts at wells operated by Chesapeake Energy and EOG Resources and a spill of gallons of fracking fluid at a site in Dimock, Pa. But the idea stressed by fracking critics that deep-injected fluids will migrate into groundwater is mostly false.

Basic geology prevents such contamination from starting below ground. A fracture caused by the drilling process would have to extend through the several thousand feet of rock that separate deep shale gas deposits from freshwater aquifers. According to geologist Gary Lash of the State University of New York at Fredonia, the intervening layers of rock have distinct mechanical properties that would prevent the fissures from expanding a mile or more toward the surface.

It would be like stacking a dozen bricks on top of each other, he says, and expecting a crack in the bottom brick to extend all the way to the top one. What's more, the fracking fluid itself, thickened with additives, is too dense to ascend upward through such a channel. EPA officials are closely watching one place for evidence otherwise: tiny Pavillion, Wyo. Pavillion's aquifer sits several hundred feet above the gas cache, far closer than aquifers atop other gas fields. If the investigation documents the first case of fracking fluid seeping into groundwater directly from gas wells, drillers may be forced to abandon shallow deposits—which wouldn't affect Marcellus wells. Much of the political opposition to fracking has focused on the Catskill region, headwaters of the Delaware River and the source of most of New York City's drinking water.

But the expected boom never happened—there's not enough gas in the watershed to make drilling worthwhile. The shale is so close to the surface that it's not concentrated in large enough quantities to make recovering it economically feasible. But just to the west, natural gas development is dramatically changing the landscape. Drilling rigs are running around the clock in western Pennsylvania. Though buoyed by the economic windfall, residents fear that regulators can't keep up with the pace of development. Robert P. Casey Jr. There are several ways to minimize this crack such as in hot weather, lower the temperature of the fresh concrete by using chilled mixing water or replacing some of this water with crushed ice.

Covering the concreted area to avoid excess evaporation or proper curing can help reduce this crack formation. The main way that oil and natural gas reserves are acquired are through the means of Fracking. Also known as hydrofracking, this method utilizes a drill that drills down thousands of feet underground, which is then flushed with millions of gallons of water along with additive chemicals at high pressures to break the rocks sheltering the reserves. This method of attainment is quite risky as it comes with many unfavorable consequences that are quite unbeneficial. Like fossil fuel plants, fracking also releases greenhouse gasses like methane Potential Health and Environmental Effects of Hydrofracking in the Williston Basin, Montana , which is worse than carbon dioxide and causes air pollution.

Alongside that, pollutants like Benzene and Xylene also leak out during the fracking process, which is known to cause serious health conditions and even death in some cases due to the long exposure to the pollutants Potential Health and. This is because the rainwater travels down to the sedimentary rocks and dissolves them creating a karst region. Also, if rain can't replenish the water table, it can either increase or decrease. When it decreases, it causes drought, which leads to water becoming unstable.

Therefore, climate change and other factors trigger sinkholes to. Crump 25 September, GroundWater Contamination Groundwater comes from surface water bodies or rain water, they soak into the dirt and rocks and build up in the tiny spaces between the dirt and rocks. Groundwater pollution occurs when a hazardous substance gets mixed and dissolves in the water soaked in the soil. Groundwater becomes contaminated in multiple ways, hen rain water or surface water contaminate the soil while soaking into the ground, it becomes polluted and carries the pollution from the soil to the groundwater, it also becomes contaminated when hazardous substances soak down through the dirt or rock into the groundwater.

Some liquid hazardous substances remain steady within the soil or bedrock. These substances act as long-term sources of groundwater contamination while the groundwater moves throughout the so or rock and mixes with them. On the other side of the debate are environmental groups, who point to the harm fracking can cause to the environment. Fracking is the process of pumping different liquids into the ground at high pressure to create fractures, cracks, and fissures in the rock so oil or gas can be extracted.

The companies involved in the fracking industry are forced to stop extracting gas. This is because there has been a moratorium placed on Hydraulic Fracturing until further notice. A moratorium is a temporary prohibition of an activity. Carbon dioxide is an asphyxiant with a density greater than air which leads it to accumulate in low or enclosed spaces, and asphyxiation fatalities will occur when there is a high concentration of CO2. In the room temperature, carbon dioxide is odourless and colourless which means that we are unable to smell or see it at the elevated concentrations. With the concentration of carbon dioxide, people will have headache and loss of consciousness, and inhale high density CO2 will cause death.

Factors that could lead to leakage of carbon dioxide includes the damage to structures and equipment and improper maintenance of pipelines. Since there is a carbon dioxide compression process on site, the leakage is similar to a pressurised release and the leak of carbon dioxide is colder than the surrounding atmosphere HSE, Fracking involves drilling a hole into the ground and injecting a combination of fluids and chemicals into the shale. The fracking fluid contains upwards of different chemicals David. The pressure of the fluid is what causes the shale to fracture, then releases natural gas. That fracking fluid is what is really dangerous, as this is what poses the biggest threat, since many of those chemicals are extremely dangerous and some are completely unknown by the public.

After the fracking process is complete, the fracking water, known as flowback, which includes water, chemicals and additives, is either collected and transferred to holding-tanks or it is injected back into the ground for storage. Hydraulic Fracturing, otherwise known as fracking is the process of injecting large amounts of sand, water, and other chemicals into the shale rocks deep beneath the ground in order to flow natural gas back onto the surface of the well. This process was invented in the early s, and has been controversial ever since.

There are two sides to the debate, one being that fracking is known to be horrible for the environment. Fracking has caused families to need to be displaced, and emitted thousands of toxic chemicals into the air causing major public health issues. At the same time, fracking has reduced the reliability on coal, which is known to be horrible for the environment; it has also brought hundreds of thousands of gallons of natural gas. What is fracking? Fracking is the process of drilling into the ground and releasing a high-pressure water mixture into rocks in order to fracture them and release the natural gases inside. The water mixture consists of water, sand and chemicals. Why is fracking dangerous? During the fracking process natural gases are realized into the well where they are drilling often contaminating the nearby groundwater with methane gases and chemical toxins.

The process begins with the Why Fracking Is Controversial? of a Why Fracking Is Controversial? vertical or angled well that can extend a Why Fracking Is Controversial? or more into the Hottone Tires Dock: A Case Study. Permission has been Why Fracking Is Controversial? for Catholic Intellectual Tradition site in Lancashire, one in Nottinghamshire and Why Fracking Is Controversial? in Yorkshire.
