  • RELATIONSHIPS BETWEEN SHALE CONTENT AND

    There is a relationship between the petrophysical properties of a reservoir rock, such as porosity and permeability, and the grain‐size distribution. Therefore, the grain‐size distribution is important in interpreting both the depositional environment and the petrophysical properties of a sedimentary rock.
