In this paper, techniques have been developed to examine the enhanced swelling effect and
viscosity reduction of CO 2-saturated heavy oil with the addition of either solvent C 3 H 8 or …

Experimental data for the diffusivity of carbon dioxide, methane, ethane and nitrogen in
Athabasca bitumen are presented in the range 25–90° C at 4 and 8 MPa. The diffusivity of …

New data for the effect of pressure and temperature on Athabasca bitumen viscosity are
presented. The viscosity data cover a temperature range of 43–120° C and pressures up to …

In this paper, the so-called pressure decay method is applied to measure the molecular
diffusivities of carbon dioxide, methane, and propane in heavy oil. In the experiment, a …

In this paper, a newly developed dynamic pendant drop volume analysis (DPDVA) method
is applied to measure the diffusion coefficients and oil swelling factors of four pure solvents …

A new technique is developed to measure the diffusivity of gas in bitumen as a function of
composition. Results are presented for a carbon dioxide− bitumen system, which is of …

This paper presents an artificial intelligence-based numerical investigation on the CO 2
solubility in live and dead oils for possible CO 2-enhanced oil recovery (EOR). A thorough …

A gravity drainage concept has been proposed and tested for in‐situ recovery of bitumen by
mobilization with soluble gases at ambient reservoir temperature conditions. Experiments …

Complex viscosity and phase-angle measurements for Athabasca bitumen and Maya crude
oil were performed with a rotational rheometer using parallel plates and a double gap …

This paper presents new data for the viscosity, density and gas solubility of Cold Lake
bitumen saturated with light gases and gas mixtures over a temperature range of 15 to 103° …
