Fractures discontinuity effect has been also scrutinized in the presence of parallelepiped networked fractures which confirmed the results in the case...

... Abstract The vapor extraction (VAPEX) process, as a non-thermal process, may be suitable for the recovery of heavy oil and bitumen. In this process, the injected solvent diffuses into the heavy oil/bitumen, reduces its viscosity, and drains it to the producing well. The VAPEX process is more...

... Abstract Vapor Extraction (Vapex) process is a viable and environmentally friendly alternative to currently used thermal methods. It involves injection of vaporized hydrocarbon solvents into the reservoir to decrease the heavy oil viscosity by dilution and de-asphalting. In high pressure...

... Abstract Vapour Extraction (VAPEX) process has been an intense research topic in recent years as an alternative technology to thermal recovery method for heavy oil and bitumen resources. In the past, most two-dimensional (2-D) transparent modelsstudies have only simulated the vapour chamber...

... Abstract Heavy oil occurring in carbonate reservoir, mostly fractured, is an important resource which accounts for one third of the total heavy oil world-wide. However production from such reservoir is challenging, due to very high oil viscosity. The Vapor Extraction (Vapex) process, a newly...

... Abstract Vapex (vapor extraction) is a promising technique for the recovery of heavy oil and bitumen reservoirs, especially for cases where steam-assisted gravity drainage and other thermal recovery methods are not economical. In the Vapex process, a solvent is injected into the reservoir...

... Abstract Vapor extraction (VAPEX) process warrants the oil industry attention because of its applicability to recover viscous oil in the cases when Steam Assisted Gravity Drainage (SAGD) fails due to the presence of bottom water aquifer, low heat conductivity, thin pay zone and excessive heat...

... Abstract Warm VAPEX, as one of the variations of vapor extraction process, is investigated in the current research which incorporates heat in a VAPEX process. The idea behind it is to heat the solvent above the dew point temperature of solvent vapors at reservoir conditions and inject...

... Abstract Vapour Extraction process is one of the newest emerging technology for heavy oil reservoirs which is based on the injection of hydrocarbon solvents into viscous oil. Despite the fact that no promising field results have been reported so far about the successfulness of VAPEX process...

... Abstract Vapour extraction (VAPEX) process is an effective heavy oil recovery technology because of its significant viscosity reduction through sufficient solvent dissolution and possible asphaltene precipitation. In the past, several researchers have studied the specific effect...

... Abstract The objective of this work was to study the effect of connate water in the progression of the Vapor Extraction (VAPEX) process for heavy oil recovery. A large fraction of the physical model tests of the VAPEX process reported in the literature have been conducted without any connate...

... Abstract The VAPEX process has attracted much attention as a potential recovery process for heavy oil, yet VAPEX mechanisms are still poorly quantified. The laboratory work described here was undertaken to explain the roles of different mechanisms in VAPEX, and to test the relative magnitudes...

... Abstract Vapour extraction (VAPEX) process is a promising heavy oil recovery technology because it can cause significant viscosity reduction through sufficient solvent dissolution and possible asphaltene precipitation. Although the VAPEX process has been extensively studied in the past two...

The first experiment tested a 3-component mixture (C 1 -C 2 -C 3 ) that was used in an earlier non-thermal dead oil Vapex test. The second...

... Abstract The Vapour Extraction (VAPEX) process is a promising technique directed towards heavy oil reservoirs that are typically thin and underlain with water, and cannot be exploited economically or technically by conventional thermal recovery methods. The VAPEX technique was developed...

... proposed mechanisms for Vapex[1]. Different from hydrocarbon gases, dissolving of CO 2 in oil results in an increase in the density of the oil phase. If CO 2 is used as a solvent in Vapex process, the density increase in oil phase near the CO 2 -oil contact region can induce a natural convection, which...
