1-1-2018 · In practice, coal seam thickness cannot be easily derived using seismic data. In order to constrain the relationship between coal seam thickness and amplitude, we present a wedge model along with a staggered grid finite difference numerical simulation. We analyze the main factors effecting seismic wave amplitude.

Pramod Thakur, in Coal Bed Methane, 2014. 8.1.2 Reservoir Properties of Coal Seams. Coal seam degasification techniques to be used in a mine depend on the reservoir properties of the coal seams being mined. Good methane control planning depends on accurate information on the reservoir properties of the coal seam and the total gas emission space created by the mining .

What is coal seam gas? – GISERADeze pagina vertalen

Coal seam gas (CSG), also known as coal bed methane, is a form of natural gas typically extracted from coal seams at depths of 300-1,000 metres. CSG is a mixture of a number of gases, but is mostly made up of methane (generally 95-97 per cent pure methane).

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 a thin film on the surface of the coal. CSG is extracted through wells drilled into coal seams.
