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 ...

Recently, one of the non-thermal oil recovery techniques, polymer flooding, has shown its potential for improving heavy oil recovery. This study investigated the potential of combining solvent-based processes and polymer ...

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 ...

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 ...

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 ...
