Fracking And Fracture Stimulation Techniques Essay

Hydraulic fracturing is the propagation of fractures in a rock layer caused by the presence of a pressurized fluid. (wiki 2011). This occurs naturally in nature, but the Hydraulic fracturing that I will speak of in this paper is a process being used by gas companies nationwide. Fracking is currently regulated by the EPA under the clean water act of 2005 (EPA.gov). However, this only partially governs the methods of injecting fluids and the retrieval of such fluids into the earth. It does not govern the types of chemicals that

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.

Fracking is a shorter form of Hydraulic Fracturing which is the extraction process of both natural gas and oil. The process involves drilling deep into the Earth’s surface. Fractures are then created by “pumping large quantities of fluids at high pressure down a welfare and into the target rock formation” (EPA, 2016). After making these openings for the gas or oil to come up (known as “flowback”) the materials can be stored. The reason the fracking process occurs is because “more usual methods of extraction may not be able to fully reach the deposits of shale gas and oil” (2015).

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

The list of ingredients used in fracking fluid is long and varied. Some are common, such as salt and citric acid, some are unexpected like coffee and walnut hulls, while others are toxic. A list released by a Congressional committee states

During the mid 2000s hydraulic fracking was starting to grow because ‘It was a good way to meet energy needs.”(source 5). Hydraulic fracking has been said to release chemicals and pollute drinking water.

One major issue with fracking is the lack of transparency of chemicals used. There has been some movement toward public awareness of the specific chemical which are pumped into the ground. It is certainly not definitive the so called halliburton loophole exempts corporations from disclosing the chemicals

With the age of constant industrial and technological growth has come the necessity for not only cost effective and efficient methods for industry, but also the need for obtaining fuel for the machines that make the modern world possible. Oil has become as precious a commodity as gold, if not more so; its attainments constantly driving the world's largest businesses and governments across the world into action. Naturally, a "quick-fix" solution to this problem is constantly sought after by oil companies wishing to provide oil on a massive scale. One of these drilling methods is known as induced hydraulic fracturing (also known as fracking).

Hydraulic fracturing is a process of collecting natural gas by pressurizing shale beds. Fracking consists of two components: a drill and fracturing fluids [4]. Well shafts are drilled into a bed of shale less than two thousand feet deep to form a horizontal fracture because less force is required to make the rock strata buckle perpendicularly to the drill [2]. After the primary shaft has been drilled, cement is poured into the surrounding area to keep the fracturing fluids from backtracking up the shaft [2]. Once the drill is placed into the pay zone, where the reservoir of oil is located, fracturing fluids are forced into the surrounding

Hydraulic fracturing, commonly known as “fracking” is a cost-efficient and innovative process to obtain natural gases from underground. Greengarbageblog.org describes

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

Modern fracking was first introduced in 1947, but it has not commercialized until 1990s (Manfreda, 2015). After almost seventy years of development, fracking technology has developed rapidly and become more efficient. But question about its safety has yet to be answer.

Unlike straight drilling for oil or gas, that uses little space, hydraulic fracturing is drilled vertically

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
