Discrete fracture model with unsteady-state adsorption and water–gas flow for shale-gas reservoirs

Energy Reports, 2023
A shale-gas reservoir possesses many complex characteristics, including coexisting free and adsorbed gases, a complex distribution of fractures, and the existence of movable water in these fractures.

Gas adsorption/desorption in silica aerogels: a theoretical study of scattering properties

, 2005
We present a numerical study of the structural correlations associated to gas adsorption/desorption in silica aerogels in order to provide a theoretical interpretation of scattering experiments. Following our earlier work, we use a coarse-grained lattice-

A method for measuring surface diffusion coefficient of coal-adsorbed gas using a differential pressure permeation method

Meitan xuebao
The surface diffusion behavior of coal-adsorbed gas is difficult to measure and quantitatively characterize, which has always been a problem or difficulty in the study of the migration law of coalbed methane (coal mine gas).

Limited storage and recovery of adsorbed gas in shale reservoirs - Insights from experiments and production modeling

Fuel Communications, 2022
Gas in thermally mature shale reservoirs is considered to exist as adsorbed volume in organic matter and free gas within pores and voids in natural fractures. Gas in-place is derived from summation of aforementioned volumes. Although industry has adopted

Computational Lattice-Gas Modeling of the Electrosorption of Small Molecules and Ions

, 1994
We present two recent applications of lattice-gas modeling techniques to electrochemical adsorption on catalytically active metal substrates: urea on Pt(100) and (bi)sulfate on Rh(111).

Quantum virial expansion approach to thermodynamics of $^4$He adsorbates in carbon nanotube materials: Interacting Bose gas in one dimension

, 2003
I demonstrate that $^4$He adsorbates in carbon nanotube materials can be treated as one-dimensional interacting gas of spinless bosons for temperatures below 8 K and for coverages such that all the adsorbates are in the groove positions of the carbon ...

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions

Advanced Engineering Materials, EarlyView.
This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.
