Research on the Occurrence State of Methane Molecules in Postmature Marine shales—A Case Analysis of the Lower Silurian Longmaxi Formation Shales of the Upper Yangtze Region in Southern China

Frontiers in Earth Science, 2022
The Yangtze region in southern China is endowed with abundant marine shale gas. Methane molecules exist in either adsorption state or free state in postmature marine shales, depending on the components of shales.

Occurrence of Irreducible Water and Its Influences on Gas-Bearing Property of Gas Shales From Shallow Longmaxi Formation in the Xishui Area, Guizhou, Southern China

Frontiers in Earth Science, 2021
Systematic studies are quite rare on the gas-bearing property and its controlling factors of the shallow Longmaxi shale outside the Sichuan Basin. In a previous study, the gas in place contents of a suit of Longmaxi shale samples with a depth range of ...

Quantum states and specific heat of low-density He gas adsorbed within the carbon nanotube interstitial channels: Band structure effects and potential dependence [PDF]

, 2002
We calculate the energy-band structure of a He atom trapped within the interstitial channel between close-packed nanotubes within a bundle and its influence on the specific heat of the adsorbed gas.

Insights into the Process of Gas Release from Organic-Rich Shale: Release Characteristics and Controlling Factors

Geofluids, 2023
Shale gas release in canister can significantly enrich our understanding in gas-in-place characteristics. However, studies on shale gas release characteristics and its controlling factors are rare.

Thermal compression of atomic hydrogen on helium surface [PDF]

, 2006
We describe experiments with spin-polarized atomic hydrogen gas adsorbed on liquid $^{4}$He surface. The surface gas density is increased locally by thermal compression up to $5.5\times10^{12}$ cm$^{-2}$ at 110 mK.

Observation of micropores in hard-carbon using Xe-129 NMR porosimetry [PDF]

, 2008
The existence of micropores and the change of surface structure in pitch-based hard-carbon in xenon atmosphere were demonstrated using Xe-129 NMR. For high-pressure (4.0 MPa) Xe-129 NMR measurements, the hard-carbon samples in Xe gas showed three peaks ...

The structure of adsorbed gas monolayers [PDF]

Accounts of Chemical Research, 1976
Some recent work aimed at understanding the structure of adsorbed monolayers and its role in determining the chemical reactivity of a surface is reviewed. The phenomenon of ordered adsorption is discussed with the object of determining what the study of the structure of adsorbed monolayers reveals about the basic interaction at a surface.

Adsorption preference reversal phenomenon from multisite-occupancy theory fortwo-dimensional lattices [PDF]

, 2014
The statistical thermodynamics of polyatomic species mixtures adsorbed on two-dimensional substrates was developed on a generalization in the spirit of the lattice-gas model and the classical Guggenheim-DiMarzio approximation.

A Model for Surface Diffusion of Adsorbed Gas in Nanopores of Shale Gas Reservoirs [PDF]

Offshore Technology Conference, 2015
Abstract Surface diffusion plays a key role in gas mass transfer due to the majority of adsorbed gas with abundant nanopores of organic matter in shale gas reservoirs. Surface diffusion simulation is very complex as a result of high reservoir pressure, surface heterogeneity and non-isothermal desorption in shale gas reservoirs.
