Scholarcy highlights

  • We show how the electrical conductivity and the fluid flow permeability of a disordered random medium may be calculated from the microscopic geometry of the pore space
  • Serial sections of the pore space are used to determine an equivalent random network of cylinders, the transport coefficients of this network are related to the conductivity of an analog random resistor network, and the latter is calculated using an effective medium approximation
  • The procedure is illustrated by detailed analysis of a Massilon sandstone
  • Article views prior to December 2016 are not included
