Coal Seam an overview ScienceDirect Topics

The level of gas produced from a coal bed is dependent on the thickness of the coal, gas content, permeability, and the depth of the coal seam. CSG extraction can create preferential fluid flow paths. Coal seams exhibit a dual porosity system, i.e., coal contains both micropores (within the coal matrix) and macropores (fractures, coal cleats).
