Abstract Important modelling techniques for CO2 storage in saline aquifers are discussed, in particular solubility trapping...

... particles. Colloidal asphaltenes may be naturally or artificially precipitated from oil if the resin molecules are removed from the surface of asphaltene panicles. Resins are normally classified as the fraction of crude oil which is soluble in normal alkane solvents such as normal heptane and normal hexane...

...% and the propane concentration should be about 35%. Now let s consider the composition of the produced fluid. This produced fluid will be a mixture of mobilized bitumen, and injected fluid. Figure 3 from Butler5, shows that the solubility of methane in bitumen at 10ºC is about 1.9 m3/m3 per MPaA. Thus...

.... Intuitively, nature of resulting distribution depends upon pressurization, solubility, diffusion coefficients, heterogeneity, and flow/saturation distributions. Upon flow back (production); many of the above factors are not fully reversed, leading to significant gas retention. It is surmised that generalized...

... better than nitrogen and yielding a higher methane recovery is likely due to its significantly higher solubility in water than that of nitrogen under the test conditions. A significant amount of CO2 was removed from the leading edge of the displacement front due to dissolution in the connate water...

However, at typical heavy oil reservoir conditions (pressure of ∼1.2 MPa and temperature of ∼10 ° C) , propane and butane have higher solubility and provide greater viscosity reduction than carbon dioxide. mehrotra correlation enhanced...

... to correction. Abstract Water content of carbon dioxide (CO2) is an important parameter in engineering applications, such as CO2 storage in deep saline aquifers and enhanced oil recovery processes. Large numbers of experimental data have been reported on the solubility of CO2 in brine. However, experimental...

Therefore, the solubility of solvent into bitumen under the ES-SAGD process operating condition are important parameter, as well as the viscosity reduction of the bitumen/solvent mixture under different solvent loading. These data should be obtained by careful experimental measurement...
