... that is required to improve recovery and pressure drop (mobility). In Ren et al. (2018) , the effect of foam generation starts to appear after injection of 1.5 PVI foam solution. The amount of displacing fluid for mobility improvement is significantly less in direct viscosification and the mobility control...

... with a slug of 0.5 wt% SAS for 0.5 pore-volumes injected (PVI). Although these two SAS species gave comparable IFT values, their oil-displacement characteristics were quite different. The oil recovery factor at 1.0 PVI was 65% with 4-15 and 67% with 7-25. At 5.0 PVI, it was 74% with 4-15 and 84% with 7-25...
