Permeability Characteristics and Controls in Fusinite-Rich Lignite [PDF]

ACS Omega
Inertinite-rich coals are widely distributed, in which fusinite (semifusinite) constitutes the dominant maceral component of inertinite. Studying the pore characteristics of fusinite-rich lignite and their impacts on coal reservoir permeability is key to gaining an objective assessment of lignite reservoir properties.
