Effects of Waterflooding, Solvent Injection, and Solvent Convective Dispersion on Vapour Extraction (VAPEX) Heavy Oil Recovery
(Faculty of Graduate Studies and Research, University of Regina, 2012-04)
In this study, the detailed effects of waterflooding and solvent injection on vapour
extraction (VAPEX) heavy oil recovery are studied by using a visual rectangular sandpacked
high-pressure VAPEX physical model with a ...
Numerical Investigation of Solvent and Thermal Hybrid Processes for Thin Heavy Oil Reservoirs
(Faculty of Graduate Studies and Research, University of Regina, 2012-12)
Western Canada has the second largest oil resources in the world. Over 90%
is heavy oil and bitumen. Vapour Extraction (VAPEX), similar to Steam Assisted
Gravity Drainage (SAGD) but using solvent to reduce the oil ...
Automatic History Match and Upscaling Study of Vapex Process and Its Uncertainty Analysis
(Faculty of Graduate Studies and Research, University of Regina, 2012-09)
Vapour Extraction (VAPEX) is a process to recover heavy oil by injecting vapourized
solvent into a reservoir. In order to ensure successful commercial application of a
VAPEX process, reliable prediction of VAPEX performance ...
An Improved Vapour Solvent Injection Technique for Enhanced Heavy Oil Recovery
(Faculty of Graduate Studies and Research, University of Regina, 2013-07)
There are tremendous heavy oil and bitumen resources in Canada, and most of them are located in the Western Canadian Sedimentary Basin. Thermal-based recovery techniques, such as steam flooding, cyclic steam stimulation ...
Coupling of Hydrocarbon Solvents of Hot Water for Enhanced Heavy Oil Recovery
(Faculty of Graduate Studies and Research, University of Regina, 2012-12-20)
Abundant heavy oil reserves and increasing demands for energy have encouraged
more and more interest in the exploitation of heavy oil. The recovery of heavy oil is
challenging due to its high viscosity. The thermal ...
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 ...
