... developed to evaluate high temperature foam half-life obtained with standard and enhanced viscosity formulations. We couple these measurements with rheology and mobility reduction evaluation in sandpack experiments. Based on these various parameters, we try to extract correlations between bulk steam foam...

... injection. We begin with CSS experiments on heavy-oil saturated sandpacks studying and clarifying the influence of the nanoparticle presence on the efficiency of the process. It is confirmed that the use of nanoparticle in the first place increases the oil recovery factor along with a higher water...

... foam (preformed foam) and a study of gel-enhanced foam on oil recovery and high permeability zone blocking for a Saskatchewan heavy oil. A series of sandpack tests with different slug sizes are conducted to investigate the oil recovery performance of polymer enhanced foam flood. The experimental...

.... Finally, sandpack flooding tests were conducted to examine the effectiveness of enhanced oil recovery by compound chemical system containing polymer, betaine and alkali lignin. The results showed that the IFT reduced to 0.001 mN/m or less at a betaine concentration range of 0.01wt% to 0.1wt% without...

... of concentration of HPMC, sodium chloride and urea on the gelation temperature, gel strength and degree of syneresis observed in gel samples were studied. The long-term thermal stability of the thermoreversible gel was evaluated. Sandpack flow experiments were conducted to evaluate the reversibility of plugging...
