Solvent-assisted heavy oil recovery methods have gained significance in recent years. The
injected solvents can be of hydrocarbon and non-hydrocarbon chemicals or a mixture of …

Various fluid phase equilibria happen in solvent-aided steam-assisted gravity drainage (SA-
SAGD). An appropriate fluid model is a prerequisite for reservoir simulation, SA-SAGD …

Solubility of light n‐alkanes in bitumen as well as density and viscosity of the bitumen‐rich
phase are the necessary data for simulation and study of the solvent‐aided thermal recovery …

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 …

Multiphase equilibrium calculations are important in primary and enhanced oil recovery
production mechanisms such as natural depletion, gas injection, and steam injection …

One of the important mechanisms in solvent-aided thermal recovery processes is viscosity
reduction due to dissolution of solvent in the bitumen. This dissolution occurs either with 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 …

Accurate quantification of phase behavior of solvent/heavy-oil/bitumen/water systems at high
pressures and elevated temperatures is of high significance for the design of vapor …

The hybrid steam-solvent injection has been considered as a promising technique for
enhancing heavy oil/bitumen recovery, while its main mechanisms including the heat …
