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 ...

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 ...
