This paper presents the measurements of bitumen thermophysical properties (density and
viscosity) over a wide range of temperatures (ambient to 200 C) and pressures (atmospheric …

Dimethyl ether (DME) was investigated as a potential additive to steam to improve steam‐
assisted gravity drainage (SAGD) in a previous simulation study. The main objective of this …

The expanded fluid (EF) viscosity model was recently developed for petroleum applications.
While petroleum fluids can be modeled as a single-component fluid, process calculations …

The development of solvent-based and hybrid (solvent+ steam) processes is hampered by
limited data and modeling methodologies for bitumen/solvent systems. The economics of …

The gravity drainage as a result of viscosity reduction is the main governing mechanism of
the solvent‐aided thermal bitumen recovery processes. Therefore, the density and viscosity …

Unconventional oils are very viscous and immobile at reservoir conditions; hence, recovery
techniques that are used in conventional reserves are not applicable and practical for heavy …

Experimental data have shown that the solubility of water in the oleic (L) phase (x wL) can
be significant at elevated temperatures. However, x wL was not properly considered in prior …

The phase-behavior and thermophysical properties of bitumen/solvent systems are of crucial
importance for heavy-oil and bitumen in-situ recovery methods. The viscosity reduction as a …

Conventional production methods in heavy oil reservoirs are not efficient primarily due to the
high viscosity of the oil. Several methods such as VAPEX and ES-SAGD have been …

Steam/solvent coinjection has been studied as a potential method to improve the efficiency
of conventional steam-assisted gravity drainage (SAGD) for bitumen recovery. This research …
