... Abstract Steam alternating solvent (SAS) process is a thermal heavy oil recovery technique, where steam and solvent (e.g., propane) are injected alternatively through the same well configuration as in the steam-assisted gravity drainage (SAGD) process. The SAS process is deemed to be more...

... of surface tension, contact angle, pore radius, and temperature on vapour pressures. The deviation of propane vapour and condensation pressures from this equation was determined experimentally by measuring them on capillary/porous media with various sizes and types, namely Hele-Shaw glass cells, silica-glass...

... and solvent utilized. This study investigates propane-SAGD (P-SAGD) and propane-steam flooding (P-SF) performance for the recovery of a Canadian bitumen from Alberta with 9.6 API gravity, 290,500 cP viscosity (at 25 °C), and 21.7 wt% asphaltenes (n-pentane insoluble) content. Three two-dimensional SAGD...

... the liquid-liquid system or in situ upgrading. In the present study, the in situ upgrading of heavy oil using propane was experimentally determined at different temperatures and pressures. The effect of the solvent-to-oil ratio on equilibrium compositions and saturated phase properties were measured...

... Abstract In our earlier works ( Pathak et al., 2010 ; 2011 ), we presented the initial results for heavy oil and bitumen recovery using heated solvent vapours. The heavy oil and bitumen saturated sand pack samples of different heights were exposed to heated vapours of butane or propane...

... as well as the integration and poor definition of gas responses (peak spreading). Colder air temperatures may also cause the heavier hydrocarbons (certainly pentanes, often butanes, and, sometimes, even propane) to condense in the gas sample line and subsequently be trapped by filters. Thus...
