This paper aims to investigate the impact of water salinity on fines migration and permeability reduction. A large-scale pre-packed Sand Retention Tests (SRT) facility...

... and Lloydminster reservoirs were selected to investigate the effect of viscosity. Results divulged great recovery of bitumen and reasonable amount of steam-oil ratio (SOR) for both processes. Applying solvent co-injection with steam reduced the amount of steam required and consequently decreased SOR, while higher...
