Review of Experimental Sorption Studies of CO2 and CH4 in Shales
(Journal article; Peer reviewed, 2019-10)In recent years CO2 injection in shale has been investigated with aim to enhance shale gas recovery (ESGR) and permanently sequester CO2. This paper reviews the state of research on CH4 and CO2 sorption in shale. We present ... -
A Hierarchy of Non-Equilibrium Two-Phase Flow Models
(Journal article; Peer reviewed, 2019-10)We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. ... -
Effect of Salts on Interfacial Tension and CO2 Mass Transfer in Carbonated Water Injection
(Journal article; Peer reviewed, 2019-02)Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) and CO2 sequestration method, which overcomes the problems associated with CO2 EOR. CO2 mass transfer and interfacial tension (IFT) are important ... -
Analytical solutions for forced and spontaneous imbibition accounting for viscous coupling
(Journal article; Peer reviewed, 2019-11-22)Fluid-fluid momentum transfer can cause higher flow resistance when fluids flow in opposite directions as compared to the same direction. Conventional modelling of flow in porous media using simple, saturation dependent relative ... -
Influence of Individual Ions on Silica Nanoparticles Interaction with Berea Sandstone Minerals
