Studying the CO2–CH4 displacement process is of great importance to understand CO2-enhanced shale gas recovery technology. However, most studies have focused on behavior in reservoir during dominant stage competitive adsorption after CO2 injection, as well recovery, efficiency, and separation displacement, while less attention has been paid initial period displacement. A model that can provide a continuous pressure gradient direction stable back-pressure at pore outlet was developed based...
Carbon dioxide enhanced coalbed methane recovery (CO2-ECBM) has been proposed as a promising technology for the natural gas enhancement well mitigation of CO2 emissions into atmosphere. Adsorption and diffusion CO2/CH4 mixture play key roles in predicting performance CO2-ECBM project, i.e., production geological sequestration potential carbon dioxide. In present work, mechanism competitive adsorption CO2/CH4/H2O brown coal were investigated by employing grand canonical Monte Carlo molecular...
Understanding the adsorption mechanism of CO2/CH4 in kaolinite clay is essential for carbon dioxide geological sequestration and enhanced gas recovery shale reservoirs. In present work, grand canonical Monte Carlo simulations were employed to investigate competitive clay. The effects pore size (1–6 nm), pressure (0.1–30 MPa), temperature (298–378 K), moisture content (0–0.122 g/cm3) on behaviors pure CH4 mixture explored in-depth. Specifically, two layers, i.e., strong weak slitlike...
Surfactant flooding has been considered as a promising approach for chemically enhanced oil recovery (EOR). However, this technique encounters several limitations, such high costs, environmental concerns, and reduced efficiency under high-temperature high-salinity reservoir conditions. Recently, nanoparticles have also proposed an alternative EOR due to their superior properties compared with surfactants. This research employs molecular dynamics simulations explore the impact of modified...
In the present study, competitive adsorption behaviour of supercritical carbon dioxide and methane binary mixture in shale organic nanopores was investigated by using grand canonical Monte Carlo (GCMC) simulations. The model firstly validated comparing with experimental data a satisfactory agreement obtained. Then effects temperature (298-388 K), pressure (up to 60 MPa), pore size (1-4 nm) moisture content (0-2.4 wt%) on were examined discussed depth. It is found that capacity much higher...

This study proposes a multiscale model combining molecular simulation and the lattice Boltzmann method (LBM) to explore gas flow behaviors with multiple transport mechanisms in nanoporous media of shale matrix. The adsorption characteristics nanopores are first investigated by simulations, which then integrated upscaled into LBM through local density parameter. In order adapt high Knudsen number matrix, multiple-relaxation-time pore-scale regularization procedure is developed. combination...
