Coal seam gas. Coal seam gas (CSG) is a type of unconventional gas. It is a natural gas, consisting primarily of methane, which is found in coal deposits. Coal seam gas collects in the coal seams by bonding to the surface of coal particles. The coal seams are generally filled with water, and it is the pressure of the water that keeps the gas as ...

Types of onshore gas Resources Victoria

Coal seam gas, also called coal bed methane, refers to naturally occurring methane in coal seams. The gas is held on coal surfaces and trapped by water pressure in the gaps and cracks in the coal seams. In order to allow the gas to flow, water is drawn away from the seams to release the gas into a gas well. The Victorian Government banned the ...

Coalbed gas content is the most important parameter for forecasting and preventing the occurrence of coal and gas outburst. However, existing methods have difficulty obtaining the coalbed gas content accurately. In this study, a numerical calculation model for the rapid estimation of coal seam gas content was established based on the characteristic values of gas desorption at specific exposure ...

Underground coal gasification Wikipedia

Underground coal gasification Wikipedia

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.

Fig. 14 shows that specific coal seams were processed depending on the price of coal. The most significant example of processing of particular coal seams at high coal prices can be seen in 2016 for seam D and E (Fig. 14 b), and to a smaller extend seam B. The mean price difference for the washing of seams D and E was in general 30/t to 40/t ...
