(Faculty of Graduate Studies and Research, University of Regina, 2012-07)
Tremendous resources of heavy oil are located in Western Canada, i.e., Alberta and Saskatchewan, most of which are contained in thin payzones. Thermal-based techniques have conventionally been utilized to enhance heavy ...
Phase Behaviour and Mass Transfer of Solvent(s)-CO2-Heavy Oil Systems Under Reservoir Conditions
(Faculty of Graduate Studies and Research, University of Regina, 2013-05)
CO2 has been found to be an efficient agent for recovering heavy oil resources worldwide through an immiscible displacement process. One major disadvantage of CO2 immiscible process is the limited solubility of CO2 in ...
