... on bitumen movbilization at the pore level. The pore-scale simulator was then used to model several scenarios for bitumen recovery using conventional and warm VAPEX, as well as SAGD and solvent-aided SAGD (SA-SAGD) processes to investigate the impact of solvent and heat on pore-scale temperature distribution...
