Conventional and unconventional hydrocarbon rocks have complicated pore structures with
heterogeneities distributed over various length scales (from nanometre to centimetre or even
larger scales). Effective characterization of the properties of such rocks based on their digital
twins is a challenging task. Digital rock physics (DRP) can be used to quantify the structural
and morphological parameters of rocks directly and predict flow transport properties at the
pore scale. Digital rock chemistry (DRC) or biology (DRB) applies when the changes in pore …
