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 ...
Utilization of co2 for pressure maintenance and improving oil recovery in heavy oil reservoirs.
(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 ...
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 ...
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 ...
