TLDR
Mudrocks and shales contain pores within the size range of 2-100nm as discussed by the authors. Flow of supercritical gas in these pores at reservoir pressure-temperature conditions falls within the slip-flow and early transition-flow regime (0.001).About:

The limits of Navier-Stokes theory and kinetic extensions for describing small-scale gaseous hydrodynamics
TL;DR: In this paper, the authors review basic results and recent developments in the field of small-scale gaseous hydrodynamics, and present recent variance reduction ideas which address the prohibitive cost associated with the statistical sampling of macroscopic properties in low speed flows.

Multiple-relaxation-time lattice Boltzmann models in three dimensions.
TL;DR: Simulation of a diagonally lid–driven cavity flow in three dimensions clearly demonstrate the superior numerical stability of the multiple–relaxation–time lattice Boltzmann equation over the popular lattice Bhatnagar–Gross–Krook equation.
