  1. Simulation Study of Warm VAPEX Process Using Water-soluble Solvent

    Qi, RundongSchulich School of Engineering2020

    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 …

    Zhou, WenjinFaculty of Graduate Studies and Research, University of Regina2011

    … 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 …

  5. Estudo paramétrico do processo de extração com solvente (VAPEX) como método de recuperação de óleo pesado

    Oliveira, Michel FernandesUniversidade Federal do Rio Grande do Norte2008

    … 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 …

    … to 1cp, which can now be drained out. This process requires large amount of water to make steam, the used water cannot be reused due to presence of high levels of bitumen in it and is currently leading to pollution. The recovered bitumen being highly viscous needs a diluent like naphtha for …

  7. Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs

    Yadali Jamaloei, Benyamin (Ben)Graduate Studies2013

    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 …
