DOI: 10.1016/j.apgeochem.2021.105028
Abstract: Abstract 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… read more here.
