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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

CO2 has been found to be an efficient agent for recovering heavy oil resources worldwide through an immiscible displacement process. One major disadvantage of CO2 immiscible process is the limited solubility of CO2 in ...
