Steam-solvent coinjection, if properly implemented, can improve the bitumen recovery efficiency of steam-only injection methods, such as steam-assisted gravity drainage (SAGD). Previous studies have shown that steam-solvent coinjection can reduce residual oil saturation lower than that of SAGD....
The effect of slurry conditioning on bitumen recovery and bitumen froth quality has been studied by using three oil sands ores tested with a laboratory hydrotransport extraction system (LHES) and a Denver flotation cell. Tests with the LHES show that an increase in slurry conditioning time...
Mass transfer at an organic solid – organic liquid interface within reservoir rock under creeping flow conditionsDownload
There is a growing recognition that knowledge gaps related to the molecular and phase state complexity of hydrocarbon resources, and their interactions within production and processing environments have begun impeding development of new or improved processes that protect the natural environment...
Recently, a commercially available biodegradable polymer, ethyl cellulose (EC) has been found to be effective in destabilizing water-in-diluted bitumen emulsions. In this study, the role of hydroxyl content and molecular weight of ECs and the effect of mixing and operating temperature in...
Viscosity, as a fundamental physical property of bitumen, has been studied extensively for the past several decades. By and large, nearly all the bitumen samples used in viscosity measurement were from hot water extraction processes that were further cleaned by solvents. A drawback of this...
