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 ...
Ultrasound Testing System for the Detecting of the Shape and Growth of a Vapor Chamber in the VAPEX Process
(Faculty of Graduate Studies and Research, University of Regina, 2011-08)
Acoustic wave detection systems are designed to estimate distances based on the
measurement of the time of arrival (TOA) of an ultrasonic wave. It has been used in
diagnoses and treatments in areas such as medicine, ...
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 ...
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 ...
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 ...
A Numerical Approach for Oil Slug Mobilization in a Capillary Tube Under Absence and Presence of External Excitations
(Faculty of Graduate Studies and Research, University of Regina, 2013-07)
This research attempts to study the mobilization of an oil drop, also known as a \slug", via the aid of a water film. This differs from other work in this area wherein the oil drop is forced through the throat of a pore ...
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 ...
Economic Evaluation of Capturing CO2 From Natural Gas Power Plant and Injecting CO2 for Enhanced Oil Recovery as an Integrated System
(Faculty of Graduate Studies and Research, University of Regina, 2013-01)
CO2 is said to be one of the most important greenhouse gas that causes global warming.
The most common sources of CO2 emission into the atmosphere are fossil fueled power
plants. With the increasing demand of energy in ...
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 ...
