Apparent Permeability Prediction of Coal Matrix with Generalized Lattice Boltzmann Model considering Non-Darcy Effect

Methane flow in coal is associated with the content of both organic matter (OM) and inorganic matter (IOM). Coal matrix contains nanopores ranging in size from a few to hundreds of nanometers, which

A novel numerical model of gas transport in multiscale shale gas reservoirs with considering surface diffusion and Langmuir slip conditions

Multiflow mechanisms coexist in shale gas reservoirs (SGRs) due to the abundant nanopores and the organic matter as a medium of gas souring and storage. The gas transport mechanisms in nanopores

PS Numerical Modeling of Adsorption and Roughness Effects on Gas Transport in Shale Using the Lattice Boltzmann Method

Advanced techniques have greatly promoted the exploitation of shale gas from shale matrix with low permeability. But the gas transport mechanism in shale is still unclear. Due to the multi-scale pore



Nanoscale simulation of shale transport properties using the lattice Boltzmann method: permeability and diffusivity

It is found that most of the values of correction factor fall in the slip and transition regime, with no Darcy flow regime observed, indicating Knudsen diffusion always plays a role on shale gas transport mechanisms in the reconstructed shales.

Multiscale Gas Transport in Shales With Local Kerogen Heterogeneities

On the basis of microand mesoscale investigations, a new mathematical formulation is introduced in detail to investigate multiscale gas-transport phenomena in organic-rich-shale core samples. The

A stochastic permeability model for the shale-gas systems

Gas flow in ultra-tight shale strata

Abstract We study the gas flow processes in ultra-tight porous media in which the matrix pore network is composed of nanometre- to micrometre-size pores. We formulate a pressure-dependent

Nonempirical apparent permeability of shale

Physics of fluid flow in shale reservoirs cannot be predicted from standard flow or mass-transfer models because of the presence of nanopores, ranging in size from one to hundreds of nanometers, in

A Lattice Boltzmann Model for Simulating Gas Flow in Kerogen Pores

Nanoscale phenomena in kerogen pores could result in complicated non-Darcy effects in shale gas production, and so classical simulation approaches based on Darcy’s law may not be appropriate for

Apparent Permeability for Gas Flow in Shale Reservoirs Coupling Effects of Gas Diffusion and Desorption

Gas transport mechanism and apparent permeability in shale reservoirs are significantly different from those in conventional gas reservoirs, which are mainly caused by the nanoscale phenomena and
