... an important role in obtaining position information of a singularity in an acoustic signal record. In this study, acoustic signals were applied to the vapor extraction process in an effort to locate and monitor the vapor chamber shape change. Abstract The acoustic wave detection system is considered...

... to that obtained by heating in some cases. In this paper, the vapor extraction (VAPEX) process is experimentally investigated to examine the effect of injecting different solvents and drainage heights on the heavy oil recovery. For this purpose, two large visual rectangular sand-packed VAPEX models...

... Abstract Hydrocarbon solvent-based enhanced oil recovery techniques, such as vapor extraction (VAPEX) and cyclic solvent injection (CSI), have showed great potential to recover heavy oil reserves. However, VAPEX suffers from low production rates because of the slow mass transfer...

... Abstract The application of VAPEX process was carried out in sintered homogeneous and vuggy porosity media with different matrix permeability and porosity, to investigate the behavior of vapor extraction process in vuggy media as a potential recovery process. The VAPEX experiments were...

... trials abandoned further research in this area. The technological breakthrough of horizontal well drilling revitalized the idea of using solvent for the recovery of heavy oil and bitumen. In 1989, Butler and Mokrys introduced Vapor Extraction Process (VAPEX) as a solvent analogue of the well-established...
