Enhanced foam stability by adding comb polymer gel for in-depth profile control in high temperature reservoirs
TLDR
In this paper, a long-term stability of gel enhanced foam as an in-depth profile control agent in high temperature reservoirs was successfully prepared by adding comb polymer gel, which can enhance the thickness and strength of foam film.About:

Fire prevention and control using gel-stabilization foam to inhibit spontaneous combustion of coal: Characteristics and engineering applications
TL;DR: Li et al. as mentioned in this paper proposed gel-stabilized foam (GSF) that can prevent and control fires in coal mines by forming silica gel structure in the bubble film using compound foaming agent (CFA), modified polyethoxylated silicone (MPS), water glass (WG) and coagulant (NaHCO3), which can nicely cover the surface of burning coal, significantly reduce the fire source temperature, thermal radiation and emission of CO, and realize stable fire extinguishing without re-burning.

Assessing the effects of nanoparticle type and concentration on the stability of CO2 foams and the performance in enhanced oil recovery
TL;DR: In this paper, the authors compared the effects of three hydrophilic metal oxide NPs, namely aluminium oxide (Al 2 O 3 ), titanium dioxide (TiO 2 ), copper oxide (CuO) as well as the effect of SiO 2 on the stability of CO 2 -foams.

The role of particles in stabilising foams and emulsions
TL;DR: Much research in emulsions can be applied to foam systems, however evidence would suggest foam systems are under a number of additional constraints, and the stability 'window' for particles is smaller, in terms of size and contact angle ranges.

Field Applications of Steam Foam for Mobility Improvement and Profile Control
TL;DR: Foams are used to control and improve the injection profile in secondary or tertiary gas-injection processes and reduce gas mobility far from the injectors as discussed by the authors, and they have shown that early, transient and usually small oil production responses to surfactant injection are real, and depend critically on the reservoir architecture and gas flood implementation.
