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 ...
Study on Wormhole Coverage, Foamy Oil Phenomenon, and Well Interference of Cold Heavy Oil Production with Sand Wells
(Faculty of Graduate Studies and Research, University of Regina, 2012-12)
In Cold Heavy Oil Production with Sand (CHOPS) wells, the presence of wormholes
is considered to be one of the most important factors that contribute to enhanced
production rate. Quantitative detection of wormholes can ...
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 ...
Motion and Mobilization of Oil Slugs in a Capillary Model Under Stationary Conditions
(Faculty of Graduate Studies and Research, University of Regina, 2012-12)
In this research, both experimental and numerical investigations are
conducted to study the mechanism behind slug flow in a capillary tube. A 1.2 mm
inner diameter capillary model is employed to represent the pore structure ...
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 ...
