Coal Density - an overview | ScienceDirect Topics

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2]. The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...
