... Abstract Cost and thermal stability are the major obstacles in using chemical additives for enhanced heavy-oil applications. Visual analysis of biodiesel in water emulsions obtained from the bitumen recovery tests from previous studies demonstrated that high pressure steam can lead to formation...

..., propane, or combination of these) and application conditions (soaking time on cyclic solvent injection durations, depletion rate) are critical. The cornerstone of the foamy oil behavior relies on its stability, which depends on parameters such as oil viscosity, temperature, dissolved gas ratio, pressure...

... carbonate core sample, were selected for the core-flood study. Static stability results revealed slower liquid drainage and collapse rates for PEF compared to that of foam even in the presence of heavy crude oil. The addition of polymer significantly improved the performance of CO 2 foam flooding during...

... Abstract This study, aims to investigate the effect of nanoparticles/polymer on CO 2 -foam stability and foamability of Alpha Olefin Sulfonate, AOS at high temperature and salinity conditions. Moreover, the effect of extra hydrocarbon phase on foam stability at high temperature and salinity...
