Coal Seam Gas : Coal Gas Essay

Coal and natural gas are the United States’ main fossil fuels used as energy sources. These fossil fuels both contain mixtures of hydrocarbons, which is a chemical compound of carbon and hydrogen (Olah, 2005). Currently, fossil fuels provide eighty-five percent of commercial energy, such as businesses, worldwide and this eighty-five percent does not even account for residential use. Imagine if the residential energy use was accounted for in that eighty-five percent (Davison, 2007). According to Goodell (2006), “Between 1950 and 2000, the world population increased by 140 percent and fossil fuel consumption increased by 400 percent. By 2030, the world’s demand for energy is expected to more than double,” with most of the electricity

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).

4. Coal Seam Gas is a naturally occurring gas found in coal seams hundreds of metres below the surface of the Earth. Like conventional gas, CSG is comprised mostly of methane and is a type of petroleum. Coal Seam Gas is extracted via different methods including

Hydraulic fracturing, or fracking, has been a hot topic in recent times due to its controversial ways. Many people argue that it is a way for the United States to become less dependent on foreign oil, while others argue that the environmental cons outweigh the pros of fracking. Fracking is the process of extracting natural gas from underground by drilling into the earth. This is done by injecting water, sand, and chemicals into a bedrock formation by a well (“Hydraulic Fracking”). By doing this, the process creates new fractures in the rock, as well as making previously made fractures bigger and easier to access (“Hydraulic Fracking”). Fracking is mostly done is areas that have low-permeability rocks like tight sandstone, shale, and some coal beds to increase the flow of oil and/or gas to a well (“Hydraulic Fracking”). The fracking process can take up to a month; the drilling team going more than a mile into the earth to extract the natural gases or oil. After the job is done, the well is cemented up (“What is Fracking”).

It implies that it is possible to make coal a fuel source that is free of (or very low in) carbon dioxide emissions and other pollutant emissions. Some of the techniques that would be used to accomplish this include chemically washing minerals and impurities from the coal, gasification (see also IGCC), treating the flue gases with steam to remove sulfur dioxide, carbon capture and storage technologies to capture the carbon dioxide from the flue gas and dewatering lower rank coals (brown coals) to improve the calorific value, and thus the efficiency of the conversion into electricity.

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

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).

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.

Hydraulic fracturing, or fracking, is the process used to excavate oil and gas trapped in shale rock.

‘Hydraulic fracturing/fracking is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc. to force open existing fissures and extract oil or gas’ (Oxford dictionaries, 2015).

First of all, what is fracking? Hydraulic fracturing is the process of drilling and injecting fluid into the ground at high

Fracking is a term that is used as a shorthand term referring to hydraulic fracturing. This is a type of drilling used for oil and natural gas within the Earth. Fracking has been used commercially for the last 65 years in the U.S... With the new technology advances in the field along with advanced hydraulic fracturing and horizontal drilling is responsible for the U.S. surging in the oil and gas production.

The American Heritage Dictionary defines hydraulic fracturing as,” the process of extracting oil or natural gas by injecting a mixture of water, sand or gravel and certain chemicals under high pressure into well holes in dense rock to create fractures that the sand or gravel holds open, allowing the oil or gas to escape. Also called fracking.”

Overview: Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release oil and natural gas trapped there. The name fracking refers to how the rock is fractured apart by the high-pressure mixture. The process can be performed vertically, but most commonly it is carried out by drilling the rock layer horizontally. Fracking has become an energy revolution in the United States as most energy experts thought that domestic energy supplies in the United States were declining. With advances in fracking, US natural gas production has climbed by as much as 25 percent in recent years.
