Review of CO2 injection techniques for enhanced shale gas recovery: Prospect and challenges
TL;DR: In this article, the performance of CO2 injection in a hydraulically fractured shale was reviewed based on simulations and field test studies, and it was shown that CO 2 injection can lead up to 26% more methane production after primary recovery, and sequester more than 60% of the injected CO2 for continuous CO2 injections, while for huff-n-puff higher amount of CO 2 is reproduced.

Nanoscale Gas Flow in Shale Gas Sediments
TL;DR: In this paper, a combination of a nanopore network connected to a micrometre pore network is used to model the gas flow in shale gas sediments, which is consistent with the Knudsen diffusivity which supports the slip boundary condition at the nanopore surfaces.

Selective transport of CO2, CH4, and N2 in coals: insights from modeling of experimental gas adsorption data
TL;DR: In this paper, the interaction energies of adsorbates (CO2, CH4, and N2) and micropores with various widths are investigated using a slit-shape pore model.
Journal ArticleDOI
Methane and carbon dioxide adsorption–diffusion experiments on coal: upscaling and modeling
TL;DR: In this article, a bidisperse modeling approach was proposed for the sorption kinetics of CO2 and CH4 in coal and enhanced coalbed methane (ECBM) production in dry and moisture-equilibrated states.
