Competitive adsorption and diffusion of CH4/CO2 binary mixture within shale organic nanochannels
Liu, Bing; Qi, Chao; Mai, Tingyi; Zhang, Jun; zhan, kaiyun; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2018)Molecular dynamics simulations were performed to study adsorption and dynamics properties of pure CO2, pure CH4, and their mixtures confined to a graphene nanochannel with width of 3.25 nm at different loadings, temperature ... -
Displacement mechanism of oil in shale inorganic nanopores by supercritical carbon dioxide from molecular dynamics simulations
Liu, Bing; Wang, Chao; Zhang, Jun; Xiao, Senbo; Zhang, Zhiliang; Shen, Yue; sun, baojiang; He, Jianying (Journal article; Peer reviewed, 2017)Supercritical CO2 (scCO2), as an effective displacing agent and clean fracturing fluid, exhibits a great potential in enhanced oil recovery (EOR) from unconventional reservoirs. However, the microscopic translocation ... -
Insight into the Pressure-induced Displacement Mechanism for Selecting Efficient Nanofluids in Various Capillaries
Wang, Xiao; Zhang, Zhiliang; Zhang, Jun; He, Jianying (Journal article; Peer reviewed, 2020)Designing fluids to regulate two-phase displacement has been of great interest because of its roles in groundwater remediation, oil recovery and water desalination. Currently, the displacement efficiency of fluids is ... -
Molecular dynamics study of di-CF4 based reverse micelles in supercritical CO2
Liu, Bing; Tang, Xinpeng; Fang, Wenjing; Li, Xiaoqi; Zhang, Jun; Zhang, Zhiliang; Shen, Yue; Yan, Youguo; Sun, Xiao-Li; He, Jianying (Journal article; Peer reviewed, 2016)The reverse micelles (RMs) in supercritical CO2 (scCO2) are promising alternatives for organic solvents, especially for both polar and non-polar components are involved. Fluorinated surfactants, particularly the double-chain ...
