A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory, in order to investigate the molecular characterization of Enhanced Gas Recovery (EGR) ...
Adsorption of CO2 on Cu/SiO2 nano-catalyst: Experimental and theoretical study
(
Elsevier B.V.
, 2022 , Article)
Copper-based silica is a promising catalyst for several reaction pathways for CO2 conversion to hydrocarbons. The activity of this catalyst in terms of conversion and product selectivity is affected by CO2 adsorption, ...
Impact of clays on CO2 adsorption and enhanced gas recovery in sandstone reservoirs
(
Elsevier Ltd
, 2021 , Article)
Carbon dioxide enhanced gas recovery (EGR) is a promising technique to sequester CO2 and boost natural gas recovery from conventional depleted and unconventional tight gas reservoirs. Clay minerals are usually present in ...
Influence of natural gas composition on adsorption in calcite Nanopores: A DFT study
(
Elsevier B.V.
, 2021 , Article)
Density functional theory is used to study the adsorption of natural gas components in calcite (10.4) cylindrical nanopores with 1–4 nm diameters. The change of adsorption energy with the diameter of the nanopores is studied ...
Large CO2 uptake on a monolayer of CaO
(
Royal Society of Chemistry
, 2017 , Article)
Density functional theory calculations are used to study gas adsorption properties of a recently synthesized CaO monolayer, which is found to be thermodynamically stable in its buckled form. Due to its topology and strong ...
Carbon dioxide EGR and sequestration in mature and immature shale: Adsorption study
(
Elsevier B.V.
, 2020 , Article)
Recently, CO2 sequestration in different shale formations has become an attractive option owing to the abundance of shale basins. However, these formations have different maturity levels and contain a variety of minerals ...
Effect of CO2 content on the natural gas production from tight gas sandstone reservoirs
(
Society of Petroleum Engineers (SPE)
, 2017 , Conference Paper)
The simulation of the gas flow in tight sandstone reservoir is a very complicated process. Several mechanisms contributed to the natural gas production in tight sandstone reservoirs. One of the main mechanisms is the gas ...
Ab-Initio Molecular Dynamics investigation of gas adsorption on α-quartz (001) for CO2 enhanced natural gas recovery
(
Elsevier B.V.
, 2021 , Article)
In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...
