Results of the continuation of a review series covering the period 2009 to 2012 on high-
pressure phase equilibria are given, including a compilation of systems investigated, recent …

Steam/solvent coinjection has been studied and pilot tested as a potential method to
improve steam-assisted gravity drainage (SAGD) for bitumen recovery. Reliable design of …

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 …

A novel experimental procedure was proposed to investigate the phase behavior of a
solvent mixture (SM)(64 mol% CH 4, 8 mol% CO 2, and 28 mol% C 3 H 8) with heavy oil …

The viscosity of bitumen is extremely high at ambient temperature and in order to produce
and transport the bitumen, it is necessary to reduce its viscosity. One of the methods to …

In the steam-based recovery processes, the coinjected gas can dissolve and diffuse into
bitumen or heavy oil for viscosity reduction. The equilibrium concentration and solubility of …

The main recovery mechanism in the solvent-based bitumen recovery processes is gravity
drainage. The density of heated bitumen or diluted bitumen at operational conditions is …

A new experimental apparatus was used to accurately measure the density and viscosity of
aromatic solvents (toluene and xylenes), of Athabasca bitumen, and of their mixtures at …

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 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 …
