A theoretical study of gas adsorption on calcite for CO2 enhanced natural gas recovery

Carchini G.; Hussein I.; Al-Marri M.J.; Shawabkeh R.; Mahmoud M.; ... more authors ... less authors ( Elsevier B.V. , 2020 , Article)

The adsorption of gas molecules (CO2, CH4, H2O, H2S and N2) on calcite (104) has been studied by means of Density Functional Theory for molecular characterization of Enhanced Gas Recovery (EGR) CO2 injection. Results show ...

Effect of surface morphology on methane interaction with calcite: a DFT study

Onawole A.T.; Hussein I.A.; Carchini G.; Sakhaee-Pour A.; Berdiyorov G.R. ( Royal Society of Chemistry , 2020 , Article)

Natural gas, consisting primarily of methane, is found in carbonate reservoirs of which calcite is major component. However, the complexity and heterogeneity of carbonate reservoirs remain a major challenge in estimating ...
