Pore-scale simulation of shale oil flow based on pore network model
TL;DR: In this paper, a pore network model is developed based on a modified shale oil flow equation to consider those combinational effects on shale oil permeability under different organic matter contents, and then is applied to provide an order analysis of those effects on the permeability of a representative shale model.

Report: a model for flows in channels, pipes, and ducts at micro and nano scales
Ali Beskok,George Em Karniadakis +1 more
TL;DR: In this paper, a general boundary condition that accounts for the reduced momentum and heat exchange with wall surfaces is proposed and its validity is investigated and it is shown that it is applicable in the entire Knudsen range and is second-order accurate in Kn in the slip flow regime.
