This paper shows that gravity drainage processes that inject blended fluids such as propane-methane or a steam-solvent tend to have an inherently unstable material balance due to the difference between dew point and bubble point...

Results and Discussions The numerical model is designed based on the two- dimensional scaled physical experiment published by Mokrys and Butler (1993). It used propane as solvent, and the operating pressure was around...

... of propane and CO 2 with Athabasca bitumen are considered. Saturation pressures were measured in a PVT cell and the density and viscosity of the saturated liquid phase were determined at temperatures between 0 and 90 °C and pressures up to 5 MPa. Data are reported for CO 2 -bitumen, propane-bitumen...

... of bitumen using excess amount of low-molecular-weight paraffinic solvent at ambient temperatures. The paraffinic solvents separate the bitumen into de-asphalted oil and an asphaltene fraction. Zhao4 conducted an experimental study of the solubility of propane (at 2.2 MPa and 40 -180 C) in the heavy oil from...

The VAPEX process may be augmented by adding heat. Heating of a horizontal wellbore will reduce bitumen viscosity sufficiently to produce a large increase...
