Study on the Swelling Characteristics of the Offshore Natural Gas Hydrate Reservoir

Entropy, 2023
The swelling characteristics of porous media in the offshore natural gas hydrate reservoir have an important effect on the stability of the reservoir. In this work, the physical property and the swelling of porous media in the offshore natural gas hydrate reservoir were measured.

The Effects of Viscosity and Capillarity on Nonequilibrium Distribution of Gas Bubbles in Swelling Liquid–Gas Solution

Colloids and Interfaces, 2023
A detailed statistical description of the evolution of supersaturated-by-gas solution at degassing has been presented on the basis of finding the time-dependent distribution in radii of overcritical gas bubbles. The influence of solution viscosity and capillarity via internal pressure in the bubbles on this distribution has been considered until the ...

Permeability evolution and gas flow in wet coal under non-equilibrium state: Considering both water swelling and process-based gas swelling

International Journal of Mining Science and Technology, 2023
Accurate knowledge of gas flow within the reservoir and related controlling factors will be important for enhancing the production of coal bed methane. At present, most studies focused on the permeability evolution of dry coal under gas adsorption equilibrium, gas flow and gas diffusion within wet coal under the generally non-equilibrium state are ...

Swelling of Na-montmorillonite in the presence of dissolved gas molecules [PDF]

Applied Clay Science
Various dissolved gases, such as CO2, H2, and CH4, may be present in the near-field geological repository due to metal corrosion or the degradation of organic waste. However, the influence of dissolved gases on the swelling behavior of bentonites, commonly used as backfill material, is still poorly understood.

Insight into the Adsorption of Methane on Gas Shales and the Induced Shale Swelling [PDF]

ACS Omega, 2020
Abstract Shale gas resources are highly abundant in the world. They can provide sustainable energy supply and have the potential to reduce energy prices. Therefore, shale gas has become one of the most important resources for oil and gas exploration and production, especially in North America today.

Saturated hydraulic conductivity of compacted bentonite–sand mixtures before and after gas migration in artificial seawater

Journal of Rock Mechanics and Geotechnical Engineering, 2023
To understand the self-healing property of an engineered barrier for radioactive waste disposal, the hydraulic conductivity of compacted bentonite–sand mixtures saturated with artificial seawater (SW) before and after gas migration was examined.
