WHAT 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 the
Coal 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 production
ISSUE: 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 has
The 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 project
surrounding 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 cost
As part of that you will see load management, you will see more traditional energy efficiency program, such as rebates on air conditioners and lighting programs. All of our utilities that are subject to this act, are require to have energy audit programs for their residential customers. So, the Commission reviews those programs as well. Cayce: You mentioned policy, what Judy describe is essentially the policy that the legislature enacted in 1980 and has amended a few times through the years, and
Food - 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 gas
Should 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 largest
injection 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 order
Fracking 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, sodium
