Study on Wormhole Coverage, Foamy Oil Phenomenon, and Well Interference of Cold Heavy Oil Production with Sand Wells

Xiao, Lei (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

Zhu, Zuojing (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.

Zheng, Sixu (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 ...

Coupling of Hydrocarbon Solvents of Hot Water for Enhanced Heavy Oil Recovery

Luo, Weiguo (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 ...
