The vapour extraction process, or ءVAPEX̕ has attracted a great deal of attention in recent years as a new method of heavy oil or bitumen recovery. The VAPEX (vapour extraction) can be visualized as energy efficient recovery process for unlocking the potential of high viscosity resources trapped in bituminous and heavy oil reservoirs. A total of 20 VAPEX experiments performed with Hele-Shaw cell utilizing three different Turkish crude oils. Two different VAPEX solvents (propane and butane) were used with three different injection rates (20, 40 and 80 ml/min). Garzan, Raman and Bati Raman crude oils were used as light, medium and heavy oil. Apart from normal Dry VAPEX experiments one experiment was conducted with CO2 and another one with butane + steam as Wet VAPEX experiment. All experiments were recorded by normal video camera in order to analyze visually also. For both VAPEX solvents, oil production rates increased with injection rates for all crude oils. Instantaneous asphaltene rate for Garzan oil, showed fluctuated performance with propane solvent. Butane showed almost constant degree of asphaltene precipitation. Instantaneous asphaltene rate for Raman and Bati Raman oils gave straight line results with the injection rate of 20 ml/min for both solvent. When the injection rate increased graphs showed the same performance with Garzan oil and started to fluctuate for both solvent. For asphaltene precipitation, propane gave better results than butane in almost all injection rates for Garzan and Raman oil. In the experiments with Bati Raman oil, butane made better upgrading than propane with the injection rate 80 ml/min. With the other two rates, both solvents showed almost same performace.

Application of Vapor Extraction (VAPEX) Process on Carbonate Reservoirs Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2009-01-01) The vapor extraction process, or VAPEX has attracted a great deal of attention in recent years as a new method of heavy oil or bitumen recovery. The VAPEX (vapor extraction) can be visualized as an energy efficient recovery process for unlocking the potential of high viscosity resources trapped in bituminous and heavy oil reservoirs.

Application of vapour extraction VAPEX process for light crude oil Kök, Mustafa Verşan; Akın, Serhat (2008-01-01) The objective of this study is to investigate the applicability of Vapex process on Garzan crude oil. Experiments were performed with Hele-Shaw cell using two different solvents (propane and butane) at three different injection rates (20, 40, and 80 ml/min). For both Vapex solvents, oil production rates increased with injection rates for Garzan crude oil. Instantaneous asphaltene rate for Garzan oil showed fluctuated performance with propane solvent. Butane showed almost constant degree of asphaltene precip...
Application of predictive Enhanced Oil Recovery models on a very heavy oil field Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2001-12-01) In this study, several predictive enhanced oil recovery (EOR) techniques are used to evaluate potential thermal oil recovery techniques that could be applied on a very heavy oil (10-12°API) field located in Southeast Turkey. Two of the EOR techniques were found to be applicable after the screening process: in situ combustion and steam injection. Sensitivity of the processes to several operating parameters, such as steam injection rate, air injection rate, and steam quality, were established. It was observed...
Development of a screening tool to assess the feasibility of solar-to-steam application for the purpose of enhanced oil recovery Abukubu, Alfred Ejiro; Artun, Emre; Sustainable Environment and Energy Systems (2020-9) Enhanced oil recovery (EOR) involves the implementation of various techniques for increasing oil recovery, which typically involves injection of an agent that help to increase the oil flow. Steam injection is a common method to increase the recovery from heavy-oil reservoirs, which contain oil that has very high viscosity that may not be produced at economic rates due to inability to flow by viscous forces. Using concentrating solar power (CSP) as a renewable-energy system is one means to attain this object...
An experimental study on single well steam assisted gravity drainage Akın, Serhat (2000-01-01) Steam assisted gravity drainage (SAGD) is one of the more popular enhanced oil recovery method of producing heavy oil and bitumen. In conventional SAGD approach, steam is injected into a horizontal well located above a horizontal producer. A steam chamber grows around the injection well and displaces heated oil toward the production well. There are several variations of this process: vertical injector-horizontal producer and singlewell (SW) SAGD where only one horizontal well is used by injecting steam from...
