TL;DR: The mechanisms and theories suggested in the literature to explain the impact of oil on foam stability in the bulk and porous media are reviewed and various ideas on an improvement of foam stability and longevity in the presence of oil are presented.

Abstract: A revision of the 1989 classic, Enhanced Oil Recovery by Larry Lake, this text, Fundamentals of Enhanced Oil Recovery, retains the original work's emphasis on fractional ow theory and phase behavior to explain enhanced oil recovery (EOR) processes. There is additional coverage on cutting edge (or current) topics, such as low-salinity EOR, steam-assisted gravity drainage, and expanded coverage on thermodynamics and foam EOR. With its frequent reinforcement of two fundamental EOR principles, lowering the mobility ratio and increasing the capillary number, it is an excellent resource for undergraduate classes.

TL;DR: In this paper, the authors explored the mechanism leading to improved oil recovery in carbonate rock and showed that brine composition and (somewhat reduced) salinity can have a positive impact on oil recovery.

TL;DR: In this paper, the authors extended the theory of foam mobilization at a critical pressure gradient to a variety of porous media, including bead and sandpacks, and showed that foam generation can be accelerated by a critical injection velocity or pressure gradient in homogeneous porous media with surfactant present.
