Viscosity is the resistance of a material to continuous deformation exerted by shear force.
High viscosity, which is sometimes greater than 1 million mPa s, at the initial reservoir …

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 …

Conventional techniques for extracting and transporting bitumen, such as steam-assisted
gravity drainage (SAGD), are associated with significant environmental drawbacks and …

In this study, a new and pragmatic methodology has been developed to accurately predict
the viscosity for light solvents (ie, methane, ethane, propane, n-butane, n-pentane, N2, and …

The resources of heavy oil and bitumen are more than those of conventional light crude oil
in the world. Diluting the bitumen with liquid solvent can decrease viscosity and increase the …

The steam-and/or solvent-based recovery processes are efficient methods for recovery of
heavy and extraheavy oils. The performance of these techniques depends on the amount 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 …

The amount of oil that is contained in the Canadian oil sands represent the third largest oil
accumulation in the world. Approximately half of the daily oil production from the oil sands …
