  • Coal Density - an overview | ScienceDirect Topics

    It is commonly assumed that interbedded rocks having densities greater than 1.75 g/cm 3 have negligible gas storage capacity.. Because of its organic richness, coal has a much lower bulk density than, for example, shale or sandstone, and, as a result, the gross thickness of coal-bearing intervals can be readily quantified using geophysical log data.
