Coalbed methane reservoir dynamic simulation comparisons using the actual steeply inclined model and ideal steeply inclined model

Frontiers in Earth Science, 2022
Numerical simulation is an efficient method to quantitatively describe the reservoir dynamics of coalbed methane (CBM) reservoirs. The ideal steeply inclined model (ISIM), assumed to be a steeply inclined plate, has been widely applied in steep coalbed ...

Effect of gas content on cavitation nuclei

Journal of Fluid Mechanics
Cavitation inception originates from nuclei in a liquid. This paper proposes a Gibbs free energy approach that provides a smooth transition from homogeneous to heterogeneous nucleation when gas is present.

TheThreeHundred Project: ram pressure and gas content of haloes and subhaloes in the phase-space plane [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We use TheThreeHundred project, a suite of 324 resimulated massive galaxy clusters embedded in a broad range of environments, to investigate (i) how the gas content of surrounding haloes correlates with phase-space position at $z=0$, and (ii) to ...

On the nature of a large anticlinal fold in the Upper Kama salt deposit, its geomechanical and gas-geochemical zonality

Учёные записки Казанского университета: Серия Естественные науки, 2021
Large (more than 10 m in height) folds complicate the longwall mining of potash salts and are accompanied with the formation of foci of gas-dynamic phenomena. In this study, to identify the folding nature, changes in the physical properties of its rocks,

Gas Content and Gas Occurrence Mechanism of Deep Coal Seams in the Shenfu-Linxing Block

Energies
The Shenfu-Linxing block in the Ordos Basin holds abundant deep coalbed methane (CBM) resources, which can alleviate gas shortages and aid dual carbon target achievement. Considering isothermal adsorption traits and parameters like vitrinite reflectance,
