DOI: 10.1016/j.fuel.2018.02.071
Abstract: Abstract Low permeability renders a significant fraction of coal seam gas (CSG) resources sub-economic. An effective permeability enhancement strategy is thereby crucial in monetising a large proportion of low permeability CSG resources. This paper introduces… read more here.
