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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
