Simulation Study of Warm VAPEX Process Using Water-soluble Solvent
Vapor extraction (VAPEX) is considered a promising alternative to the SAGD process to recover Alberta's heavy oil and bitumen resources. In the past, researchers have found that the main drawback of the VAPEX process is its slow oil production rate due to the inherent mechanism of relatively slower …

Effect of Temperature on Performance of Vapex Process for Heavy Oil
… option for improving the oil drainage rate of Vapex (Vapor Extraction) in extra-heavy oil formations. This study was aimed at quantifying the upper limit of oil rates achievable with heated solvent injection. Results of the performed research can also be used to assess the applicability of …

Estudo paramétrico do processo de extração com solvente (VAPEX) como método de recuperação de óleo pesado
… may be explored with new concepts. The VAPEX process is a promising recovery method since its invention in 1991 by Dr. Roger Butler. The process consists in two horizontal wells, parallel between themselves, producer and injector, where vaporized solvent is injected with the objective of …

Ultrasound Testing System for the Detecting of the Shape and Growth of a Vapor Chamber in the VAPEX Process
… media during vapor chamber expansion in the VAPEX process. Vapor extraction is a potential nonthermal recovery process used to improve the recovery factor from heavy oil and bitumen reservoirs. In this process, a mixture of light hydrocarbon vapors close to its dew-point, such as propane or …

A Numerical Simulation Study of the N-SolvTM Process
… are a potential alternative. Vapor Extraction (VAPEX) and N-SolvTM are two potentially competing solvent recovery processes that offer water-free operation. Although VAPEX has demonstrated success in laboratory experiments, it has not been demonstrated to be technically or commercially …

An Improved Vapour Solvent Injection Technique for Enhanced Heavy Oil Recovery
… injection processes, such as vapour extraction (VAPEX), and cyclic injection processes, such as cyclic solvent injection (CSI). The low production rates of VAPEX are observed in field tests. CSI does not show exciting results due to the quick pressure depletion and the sudden reservoir energy …

Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
Vapour extraction (VAPEX) process has a low production rate and is not suitable for thin reservoirs due to lack of efficient gravity drainage. Cyclic solvent process (CSP) has been proposed to improve the production rate of solvent processes. A major problem of CSP is that during production, the …

Mass transfer studies in heavy oil recovery using solvents
… of bitumen. One such method, vapor extraction (VAPEX) process uses gaseous solvents like hydrocarbon solvents and CO<sub>2</sub> to reduce bitumen viscosity. Vaporized solvents is introduced laterally to bitumen to reduce its viscosity and the less viscous bitumen drains under gravity. …

Dynamic and Static CO2 Mass Transfer Processes in Bulk Heavy Oil and Heavy Oil Saturated Porous Media
… and tertiary methods. Vapour extraction (VAPEX), CO2 flooding, CO2 Huff-and-Puff are some of the solvent based approaches used in the industry to enhance oil recovery performance. These methods involve the injection of a vaporized solvent into the reservoir in order to reduce the viscosity …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… gravity drainage (SAGD) and vapour extraction (VAPEX) often do not work for recovering heavy oil in such thin reservoirs. The enhanced cyclic solvent process (ECSP) experimentally shows its potential to increase heavy oil recovery in such thin formations by using methane (CH4) and propane (C3H8) …
