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 ...
Oil Recovery Mechanisms and Asphaltene Precipitation Phenomenon in CO2 Flooding Processes
(Faculty of Graduate Studies and Research, University of Regina, 2012-12-17)
In this thesis, the mutual interactions between a light crude oil and CO2 at the reservoir temperature were experimentally studied. The oil recovery mechanisms and asphaltene precipitation phenomenon in tight sandstone ...
