... the Arrhenius energy published by Strausz and his co-workers at the University of Alberta. An examination of field results for carbon dioxide production in Athabasca projects shows that the predictability of carbon dioxide is less simple. The carbon dioxide production is not erratic but goes through a distinct...

... Abstract Water content of carbon dioxide (CO 2 ) is an important parameter in engineering applications, such as CO 2 storage in deep saline aquifers and enhanced oil recovery processes. Large numbers of experimental data have been reported on the solubility of CO 2 in brine. However...

...) . However, mixtures of carbon dioxide and propane may be a more viable option. Currently, carbon dioxide is expensive but costs are expected to decrease if environmental incentives to sequester carbon dioxide are introduced. Carbon dioxide may also be a better Vapex solvent than methane because it is more...

... Abstract CO 2 -sequestration in deep geological formations has been suggested as an option to reduce greenhouse gas emissions. Saline aquifers are one of the most promising options for carbon dioxide storage. It has been investigated that if the layer of aquifer is deep enough, at depths more...

... that the largest effect on silica production in SAGD is the steam zone pressure. Silica levels in produced water tend to increase with temperature. However, a significant suppressive effect of silica dissolution from quartz sands is provided by the presence of carbon dioxide dissolved in steam condensate. Lesser...

... extraction employs a substance above its critical temperature and pressure as a solvent; in this state the substance has both liquid- and gas-like properties that can be controlled by the pressure and temperature of the extraction process. In this paper, results of studies using supercritical carbon dioxide...

The optimized solvent composition thus identified was then used in Vapex experiment in a physical model packed with crushed reservoir rock. It was seen that the chosen solvent mixture (containing carbon dioxide...

..., making them essentially immobile at reservoir temperatures. However, the viscosity of bitumens and heavy oils can be decreased dramatically by mixing them with solvents or light gases at high pressures. The decrease in bitumen viscosity is related to the gas solubility. 2 For example, carbon dioxide...

... Abstract This paper presents the results of an investigation on the application of gel placement in an attempt to reduce the permeability of a carbonate porous medium to water and supercritical carbon dioxide, as encountered in the CO 2 flooding of carbonate reservoirs. A 7500 ppm high...

... dioxide, generally referred to by the name "aquathermolysis", are in fact solvolytic reactions by their nature. The results of this work suggest strongly that the production of the acid gas gases, hydrogen sulphide and carbon dioxide, will be suppressed in SAGD operations if a solvent is coinjected...

... the virgin pressure of the reservoir is low. In such cases, the amount of solution gas is limited, and the bitumen at steam zone pressure is often undersaturated with respect to the available methane. The polar gases, hydrogen sulphide and carbon dioxide, on the other hand, are almost entirely produced via...

... for Vapex process using a scaled sand packed model. CO2 based Vapex Carbon dioxide (CO2), has been of interest to the oil industry for over 25 years. Originally, the interest was in its potential for enhanced oil recovery (EOR). More recently, that interest has been eclipsed by its perceived role in global...

... Abstract The addition of certain amounts of non-condensable gas to the steam assisted gravity drainage (SAGD) process has been known to reduce the steam consumption. The addition of small amounts of such gases (i.e. carbon dioxide) may improve oil recovery as the gas accumulates at the upper...

The comparison indicates the superiority of the new method over the other methods used to calculate viscosity of natural gases...

... to the commercialization of the CT process at Suncor, carbon dioxide was also investigated as a CT process aid. With the concerns over carbon dioxide related to the Kyoto protocol, the extent to which carbon dioxide is trapped and chemically sequestered in the CT process has been investigated. The mechanism by which...

Comparison of the three cases shows that case (b) and (c) are accompanied...

Although methane is produced in part via bitumen, there is a significant contribution from methane dissolved in water as well. Other gases, such as carbon dioxide and hydrogen sulphide, are primarily produced by virtue...
