Coal Seam Gas Coal Gas Essay - 1162 Words

Coal Seam Gas What is coal seam gas? Coal Seam Gas (CSG) is a natural methane gas found in coal seams made by coal forming under the earth for millions of years. Countries such as the United States and China have utilised it for energy needs. Methane lines the inside of the coal cracks, pores and micro-pores and is found in the open fractures (cleats) and seams. (1) CSG is also known as Coal bed methane (CBM) and Unconventional Gas. Unlike coal itself, the gas lacks hydrogen sulphide. It is extracted by drilling a steel encased hole into the coal seam known as fracking. The gas is released from the coal as water is pumped out, the water and gas are separated and the gas then compressed into a natural gas pipeline. Where is it found in Australia? The CSG industry in Australia is around 20 years old, with the first business construction of a well occurring in Queensland in the mid 1990s. Australia has substantial identified reserves of CSG occurring in coal basins in Queensland, New South Wales, Victoria, Western Australia, South Australia and Tasmania. (2) The biggest known basin being the Surat basin: which occupies 300,000 km2 of Southern Queensland and Northern New South Wales. (1) Fig 1.0 – The major basins in Australia that hold coal seam gas. (1) What is fracking? ‘Fracking’ (Hydraulic Fracturing) is the technique of mining that extracts oil or gas from the underground via wells drilled into the seam. (3) Steel pipes are then put into the newly drilled hole andShow MoreRelatedCoal Seam Gas2081 Words   |  9 PagesWHAT IS COAL SEAM GAS (CSG)? CSG is a naturally occurring methane gas which is known as Coal Bed Methane (CBM). It is a-by product of ancient plant matter that has formed over millions of years by the same natural processes which produce coal. Not long ago this gas was identified as a major problem in the underground coal mining industry due to it’s high flammability despite this, it is now recognised as a very profitable resource. The coal seams are generally filled with water and it is theRead MoreCoal Seam Gas853 Words   |  3 PagesCoal seam gas (CSG) is mostly composed of methane and is typically attached to coal underground. This gas is released when pressure on the coal seam is reduced by removing water from the seams (Queensland Government, 2014 ). In order to obtain the gas, wells are drilled into the coal seams, bringing water from the coal seams to the surface. This process reduces pressure and allows the gas to be released (Queensland Government, 2014 ). CSG is an important energy resource in Queensland and productionRead MoreCoal Seam Gas Exploration And Development1828 Words   |  8 PagesISSUE: Coal seam gas exploration and development is rapidly increasing within Australia (Woodman and Silver, 2013). This increase has sparked significant concern within the community about the potential environmental, social and economic impacts that could result, which could possibly put a standstill to CSG mining, costing the state millions of dollars in revenue (Jaques and Galloway, 2012). BACKGROUND Coal seam gas or CSG is a naturally occurring found in coal seam deposits. Australia hasRead MoreThe Exploration And Development Of Coal Seam Gas1092 Words   |  5 PagesThe exploration and development of coal seam gas (CSG) have important strategic significance. On one hand, it improves energy structure and increases energy resources. On the other hand, the CSG indirectly protects the global environment by using the clean energy. Although the CSG has so many benefits, CSG extraction is still an industry of high input, high risk and high technology needing under the current conditions. In order to reduce its potential risk, it is essential to operate the projectRead MoreHarmful Effects On The Environment And Surrounding Agricultural Lands Are The Negative Externality Effects Associated With Coal Seam Gas1691 Words   |  7 Pagessurrounding agricultural lands are the negative externality effects associated with coal-seam gas. This stems from problems such as the exhaustion and/or contamination of clean water resources. 1b) As seen from figure one, negative externality creates a social marginal cost that is substantially higher than the actual level of coal-seam gas mining (private marginal cost). It is evident that coal seam mining has an ‘un-priced’ cost, which is not included in the private marginal costRead MoreShould Farmers Forced The Gas Exploration On Their Lands?1134 Words   |  5 PagesShould Farmers be forced to Allow Coal Seam Gas Exploration on Their lands? Introduction Coal Seam Gas which is commonly referred to as CSG is a type of natural gas found in coal deposits. Over millions of years natural gas is formed from plant matter which when under pressure forms natural gas. Coal seam gas and natural gas are used in the same form and in the same way generally for cooking and heating whilst it is commonly used for industrial purposes and electrical generation. Australia’s largestRead MoreThe Effects Of Co2 On The Permeability Of Indian Bituminous Coal1521 Words   |  7 Pagesinjection on the permeability of Indian bituminous coal at different confining and injection pressure. The major approach of the journal is to clarify about when and how would the incensement of injection pressure have impact on the permeability of coalbed methane. As a final year Civil Engineering student, I found this journal is educational and inspiring. The research shows a comprehensive explanation of how pressure and stress of permeability of coal to sub-critical CO2 is tested. Summary In orderRead MoreFracking And Fracture Stimulation Techniques Essay1081 Words   |  5 PagesFracking in CSG mining is a process where a mixture of water, sand and additives are pumped under pressure into a coal seam to open up already existent cracks in the coal strata. Fracturing fluid is 97%-99% sand and water, with a small amount of commonly used biodegradable compounds to prevent bacterial growth and turn the fluid into a gel so it can be pumped more easily (What is coal seam gas? - NSW Resources and Energy, 2016). The CSIRO suggests the components of fracturing fluid are: guar gum, sodiumRead MoreEnvironmental Awareness And Sustainability Project3152 Words   |  13 PagesFood - Coal Seam Gas or Farming Name: Abdullah-AL Junayed Chowdhury S186646 2 1. Introduction As the world’s population is increasing, the demand of the energy usage is also increasing and the direct solution is to find and implement newer energy sources. As a consequence, sometimes farming lands are exploited Mining companies are investigating and discovering different types of energy sources to meet the energy demand. One option for a different kind of energy supply is coal seam gas. Coal seam gasRead MoreFossil Fuel And Fossil Fuels1485 Words   |  6 Pagesfossil fuels were formed. Fossil fuels were converted into coal, oil, and natural gas (U.S Department of Energy, 2013). Fossil fuels are considered to be non-renewable energy. Fossil Fuels are considered to be this because they are a one-time energy source. Since it takes millions of years for fossil fuels to form, once they are all gone they are basically gone forever (Alterative Energy, 2015). One type of fossil fuel is coal. Coal is a hard, black colored, rick-like substance that is made up
