Driftless Area

When choosing where to live, you must first consider the job opportunities. In the Coastal Plains region, you will have a diverse selection of jobs. One line of work includes oil mining. Oil discoveries from the past such as the Spindletop Oilfield in 1901, have shaped and improved the overall standards of this region. Not only are the shipping and warehousing industries involved with this occupation, but they grew up out of the

Hydraulic fracturing is also known as “fracking” is a technique which involves drilling down, then horizontally as far as 10,000 feet below the surface to release natural gasses stored in the sedimentary rock known as Shale. The channel is then encased with concrete or occasionally steel to allow millions of gallons of water to be injected into the wellbore. Most water used in fracking comes from surface water sources such as rivers, lakes, or other accessible bodies of water nearby. Not only is there water being funneled into the wellbore, but also a mixture of sand and other chemicals. When the high-pressure mixture is injected underground it fractures the Shale around the wellbore and creates fissures. The fissures are then held open with

The extraction of natural gas requires a borehole which is dug down to the deep shale formation. After the hole is dug, a steel pipe is inserted into the borehole where it is encased with cement on the outer perimeter of the pipe. A perforation gun is lowered into the cement-encased piping. Using an explosive, the perforation gun perforates the casing and puts initial fractures into the shale at targeted locations. The shale is fractured further by inserting fracking fluids, which consists of 98% water and sand, plus 2% proprietary fluids. The fracking fluids are pushed down into the wellbore and pressurized to 3000 psi causing the initial fracture to spread in the shale, along the shale natural fracture lines. The sand in the fracking fluids keeps the created fractures open which allows the gas from the shale pores to flow into the casing and then to the surface, where it is collected.

Hydraulic fracturing, better known as fracking, is the process of removing oil and natural gas from in between layers of shale and other low-permeability rocks. This is done by drilling both a well and a horizontal tunnel. Sand and chemicals are shot through the tunnel with incredible pressure, which cracks the shale allowing the oil and natural gas to travel up the well (Jackson, 2014). Fracking has caused a breadth of controversy due to the economic benefits and the geological consequences.

While families migrated toward this region, the western plains were experiencing some of the greatest droughts to ever occur. In addition to this, “the massive plowing, plus overgrazing by cattle, largely destroyed the native grasses that held the once rich soil in place” (West 1). These settlers were farming on foreign land that they were absolutely new to and maintained the unyielding perception that “land could be shaped by human will” (Black Blizzard). Their rationale was so clouded by the belief that the resources present in the moment were limitless, that they did not see the accumulating cloud of dust slowly slithering across the land. These uneducated farmers were planting soil-depleting crops, which “caused the destruction of organic matter or the loss of minerals in excess of those

Fracking is a process in which water, sand, and chemicals are injected into the ground to extract natural resources such as oil and natural gas (Boone and Robinson, 2015, p.69). The process of fracking is the vertical

Unlike traditional oil or gas drilling, hydraulic fracturing uses a combination of chemically treated water and salt to break shale rock; this releases oil or gas that would not be accessible with traditional drilling methods. The oil or gas is then displaced by the water and salt and eventually collected

It is then mixed with between 1 and 8 million gallons of water and sand. This is called Fracking fluid. In the US right now there are around 500,000 active gas wells. A well can be fracked around 18 times, so altogether to run all the wells in the US, it would take 360 billion gallons of chemicals along with 72 trillion gallons of water. Of the fracking fluid used 50 -70% of it is left in the ground and the fluid is non bio degradable causing contamination to nearby groundwater and evaporating which releases volatile organic compounds into the atmosphere contaminating the air. One of the biggest arguments that people who are for fracking say that it is better as there are less Co2 emissions. Although this is true, during the fracturing process methane gas is used and if they don’t cap the wells properly, which although quite rare can happen, the methane gas can be released into the air causing multiple environmental hazards. So although they can argue that their Co2 emissions are lower, they use methane a gas that is much worse for the environment. The methane gas is also contaminating the water near the wells with water sources near the wells reportedly having 17 times higher methane concentrations than water sources not near the wells.

Hydraulic fracking is vertical well bores are drilled thousands of feet into the earth, through sediment layers, the water table, and shale rock formations in order to reach the oil and gas. The drilling is then angled horizontally, where a cement casing is installed and will serve as a conduit for the massive volume of water, fracking fluid, chemicals and sand needed to fracture the rock and shale. In some cases, prior to the injection of fluids, small explosives are used to open up the bedrock. The fractures allow the gas and oil to be removed from the formerly impervious rock formations. Although fracking has technically been in existence for decades, the scale and type of drilling now taking place, deep fracking, is a new form of drilling

According to an article in The New York Times, hydraulic fracturing is best described as the technique used to drill down into the earth using a high pressure water mixture to fracture the rocks and extract the natural gas and oil. Approximately one million wells have been fracked since the 1940’s, most of these are vertical wells that drill into porous sandstone or limestone. New technology has allowed for horizontal drilling to capture gas from shale rock. Water, sand and other chemicals are injected into the rock at a high pressure to create the fractures that release the gas. The chemicals added to the water dissolve minerals, kill bacteria that may plug up the well and

Before starting the process of fracking the drilling site must be suitable. The site must be four to six acres, cleared from large equipment, and have plastic lines placed for drilling waste . In addition, their must be a water impoundment with about 4 million gallons of water that is collected and stored in order to be pumped into the well. This water is transferred by tanks, trucks, or plastic-lined ponds . Hydraulic fracturing processes begins by drilling a vertical well. The drilling goes through aquifers and dozens of geological layers before it reaches desired location of shale rocked believed to contain natural gas. The drill begins drilling horizontally and a production casing is then inserted into the borehole which is surrounded by cement to case it. Next, a perforating gun is fired to make the shale rock more penetrable. A mixture of water, sand, and various undisclosed chemicals are then pumped in at high pressure in order to fracture/break the shale for the gas to escape. After the fissures in the shale rock occur the natural gas is released through the fissures and is taken up the well to the surface. Last, the water byproduct, also referred to as flow back water or produced water is released and travels back to the surface. The gas that is collected is then processed, refined, and shipped to distributors

Hydraulic fracturing also known as fracking is a process used to release natural gasses from the shale rocks. Shale rock is a type of that is found underneath the earth’s surface. It consists of mud, clay, and other minerals. In order to release these gasses companies must drill up to 10,000 feet into the ground, where high-powered fracking fluid or water mixed with sand and chemicals are put into a metal pipe that is put into place to ensure the stability of the hole that is being drilled. “There are approximately 40,000 gallons of chemicals used per fracturing. There are 600 chemicals used in the fracking fluid, some of which are lead, uranium, mercury,…” On average it takes anywhere from one to eight million gallons of water to complete

First let me explain what this process involves and how it works. Fracking involves using a 99.5% sand, water, and special chemical additive to help bore through rock to release the natural gas so it can be harvested (Loki (2015)). It is this

Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the inner gas. Water, sand, and many chemicals are injected into the rock

Before fracking starts a fluid is made to pump underground and recover the natural gas. The fracking fluid mixture is made up of lots of water, sand and chemicals, which cracks the rock layer and helps retrieve the natural gas. Once they have all the gas the fluid
