Introduction Natural gas has as of late risen as a generally clean vital source that offers the open door for various areas around the globe to decrease their dependence on energy imports. It can likewise serve as a transition fuel that will consider the movement from coal to renewable energy assets while serving to diminish the discharges of CO2, criteria poisons, and mercury by the power sector. Hydraulic fracturing and horizontal drilling make the extraction of firmly bound characteristic gas from shale developments monetarily practical. Yet these advancements are not free from ecological dangers, particularly those identified with territorial water quality, for example, gas relocation, contaminant transport through affected and naturally …show more content…
The extensive use of water for hydraulic fracturing is likely to restrict the supply of water towards irrigation for agriculture, residential, and business use. In areas with dry climates such as New Mexico, Texas and Oklahoma this allocation of water is likely to intensify drought conditions. Finally a recent phenomenon that has been encountered is the increased seismic activity in areas surrounding hydraulic fracturing well sites. Induced seismic activity is used to describe the transfer of utilized hydraulic fracturing liquids as a part of profound infusion wells either at too high a pressure or to close to a current geologic flaw causing disruptions that can be felt as …show more content…
Hydraulic fracturing liquids comprise of water that is blended with proppants and chemicals before infusion into the well under high weight (480 to 850 bar) so as to open the current cracks or launch new cracks. The proppant (usually sand) speaks to by and large ~9% of the aggregate weight of the fracturing liquid and is obliged to keep the cracks open once the pumping has ceased. The number, sort, and convergance of chemicals included are represented by the geographical attributes of every site and the compound qualities of the water utilized. The fracturing liquid commonly utilized as a part of the Marcellus Shale is called slickwater, which implies that it doesn't contain consistency modifiers that are frequently added to hydrofracture different shales in order to encourage better proppant transport and arrangement. Concoction added substances in the liquids utilized for hydraulic fracturing as a part of the Marcellus Shale incorporate grinding reducers, scale inhibitors, and biocides. Eight U.S. states presently oblige that all chemicals that are not viewed as exclusive must be distributed on the web, though numerous organizations are intentionally revealing this data in different states. However, many of the chemicals
In the video “Fracking Hell: The Untold Story” by Link TV explains how natural gas has been a huge problem not only for the earth in general but for everyone and everything living in it. The video explains how North East of Pennsylvania is having difficulties to conserve a healthy environment and people. North East of Pennsylvania is the main sources to extract gas and send it throughout the United States for gasoline and so on. However, this action is wonderful for the cost of gas, but has a huge impact on the environment and the people living in Pennsylvania. A lot of people in this state are worried having health issues because everything is not usable is being thrown out to the rivers where they get their fresh water.
The documentary ‘Gasland” is a telling tale of the terrible consequences of natural gas mining in the US. The filmmaker, Josh Fox, travels around the country visiting different homes that are in very close proximity of natural gas drilling sites after receiving a $100,000 offer from a natural gas company to use his land as a drilling site . The film focuses on how the drilling sites not only leave ugly scars on the land, but also the horrendous health problems people get from drinking the contaminated groundwater.
Hydraulic fracturing, also called fracking, is a technique designed to release the gas and oil from shale rock hidden underneath earth’s surface. The term fracking itself is referring to the point at which the shale rock is broken open by a high-pressure mixture of water, sand, and chemicals. Oil and gas fracking can be dangerous to the environment and also to humans. “In 2011, energy company Cuadrilla suspended test fracking operations near Blackpool, in Lancashire, after two earthquakes of 1.5 and 2.2 magnitudes hit the area. A subsequent study found it was highly probable that shale gas test drilling triggered the tremors” (BBC). Although these tremors were too small to do any damage above ground, this was still a test drill. If an oil rig were to become operational, the tremors could increase in magnitude, causing significant damage both above ground and underneath the earth’s
There are a number of points at which Fox talks about how fracture fluid contains a mix of over 596 chemicals and how they are undisclosed because they are considered proprietary. Not only do individual states mandate the full public disclosure of fluid additives, but the federal government does as well, and the Occupational Safety and Health Administration (OSHA) requires that this information be kept at all well sites (Energy In Depth). Since then, it has been proven that fracture fluid is comprised almost entirely of water and sand, and typically containing less than one percent of an average of 12 components, most of which can be found around the house. Additionally, oil and gas is not the only use of fracturing, as it has also been used to access sources of water and geothermal
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
Gas in shale formations are“low in permeability,” making it very tedious to extract, but with the increase in technological knowledge in fracking and horizontally drilling into shale beds, the vast reserves of natural gas resource could be extracted (4). Fracking is a large industrial operation that boost the “productivity of a oil or gas well” (5). It is a process by which, under very high pressure, a mixture of water, chemicals, and sand, are pumped into shale formations that causes fractures in the rocks to open wider or create new fractures that would allow otherwise trapped oil and gas to flow into the wells (6).
Texas, with its abundances of natural resources, is facing a new demon, one that doesn’t even seem possible, a shortage of water. Water, without it nothing can survive. Texas is the second largest state for landmass in the nation and ninth for water square miles. Within the borders of Texas are more than 100 lakes, 14 major rivers, and 23 aquifers, so why has water become such an important issue for the state? Politicians and conservationists all agree that without a new working water plan, the state could be facing one of the most damaging environmental disasters they have ever seen. The issues that shape the states positions are population growth, current drought conditions, and who actually owns the water.
Current research, in the field of public health, is looking at the adverse health effects of hydraulic fracturing on community members. This research is focused on looking for evidence-based research in processes, procedures, materials and cleanup from drilling and running a well. In recent years, several states such as Maryland and New York, have called for special advisory commissions to examine the potential adverse health implications for the community if the moratoriums are lifted and fracturing is allowed to start. A lot of the previous research conducted focused on the anecdotal perspective of the adverse health effects. This perspective does not offer scientific verification that the fracturing processes are causing them or evidence where the contaminations are coming from.
With the changes coming from global warming and increased greenhouse gasses, there will be many impacts to Texas over the coming decades. One of these impacts is the effect on our water resources. Texas’ main source of fresh water is precipitation, coming almost completely from rainfall. With temperatures rising and with an expectation that precipitation levels will most likely drop in coming years, this combination will put great stress on our water reservoirs. If we continue our current usage rates of water and if recent climate changes continue to persist then we will see a huge decrease in our water reservoirs. Also, given that we are in a drought, it appears that conditions are getting worse every year, posing a serious problem for the future if this issue is not addressed now.
Ever since the process of hydraulic fracturing—or fracking—made its entrance to the oil industry, issues and problems surrounding the process have become a common occurrence. Fracking is the controversial process of horizontal drilling (see fig. 1), where millions of gallons of water mixed with sand and chemicals are pumped deep into an oil well to extract natural gas from the earth’s crust (Ehrenberg 20). This practice has even been banned in some places (see fig. 1). The methane that comes out of the earth and the water used—called fracking fluid—has the potential to cause problems with local ground water supplies. Whether or not fracking is the cause of these problems, concern should be observed during the fracking process to reduce the chances of water contamination among residential areas.
Fracking can cause harm to people, animals, and nature. When they drill into the ground they are pumping chemicals to extract the gas and oil, and this contaminates the water sources around it. “An editorial on gas extraction from the Marcellus Shale in the Post-Star, a newspaper in Glens Falls, New York, contends, “New York state simply can’t take the risk. There are plenty of places to find fuel. It’s not so easy to find a new water supply for 17 million people.”” (Hydrofracking
One of the biggest natural resources used in fracking is water. On average, around one to eight million gallons of water are used on a fracture job. There are also around 500,000 active fracture sites around the world and each site can be fractured around 18 times. This means that roughly 72 trill...
Nationwide, many other cities and counties have banned fracking as well. All states should look into finding alternative sources of energy, instead of using devastating practices like fracking to extract non-renewable resources. Hydraulic fracturing is a technique that combines water mixed with chemicals that is then pumped into shale deposits, allowing access to underground stores of natural gas and other resources. EnergyFromShale.org shows the fluid mixture comprises 90% water, 9.5% propping agents such as sand, and 0.5% chemical additives.
Fracking has become a highly controversial and publicized topic due to rising concerns and growing analysis into the mutual benefits of hydraulic fracturing to retrieve natural gas and oil reserves. With concerns of water pollution, mismanagement of toxic waste and irreversible
Numerous reports have been given on the dangerous affects of hydraulic fracturing. One such affect that has been noticed is that drinking water wells near the fracturing sites have been contaminated. During the hydro-fracking process, injected fluids that help to break and keep open the rock bed where the natural gas is kept, have “been known to travel three thousand feet from the well (Goldman).” This fluid could have the potential to enter and contaminate any water well for homes around hydraulic fracturing sites. This incident is one of the major problems that people want to figure out and know about before they allow a fracturing site by them. It has been the most feared outcome of having a fracking site nearby, and it is highly appropriate. One site in Wyoming had this happen, “…in August, EPA reported that eleven of thirty-nine drinking-water wells near a Wyoming hydraulic fracturing operation were contaminated with chemicals used in the fracturing process (Hobson EPA).” In Pennsylvania, another such case occurred, “There have already been severe pollution cases in Pennsylvania, mo...
