“… 21 The interaction effects associated with the surface charge of NPs and the net charge of surfactants are widely studied. For example, Zhao et al 22 used polydimethyl-siloxy (PDMS) coated with SiO 2 NPs to test aerosol-OT (AOT; or sodium bis(2-ethylhexyl) sulfosuccinate), which is an anionic surfactant. The surface charge and the net charge interactions between NPs and surfactants improve the stability of foam through different mechanisms, and a longer foam half-life has been reported between NPs and oppositely charged surfactants.…”

Carbon dioxide (CO 2 ) in enhanced oil recovery (EOR) has received significant attention due to its potential to increase ultimate recovery from mature conventional oil reserves. CO 2 -enhanced oil recovery (CO 2 -EOR) helps to reduce global greenhouse gas emissions by sequestering CO 2 in subterranean geological formations. CO 2 -EOR has been exploited commercially over recent decades to improve recovery from light and medium gravity oil reservoirs in their later stages of development. CO 2 tends to be used in either continuous flooding or alternated flooding with water injection. Problems can arise in CO 2 -flooded heterogeneous reservoirs, due to differential mobility of the fluid phases, causing viscous fingering and early CO 2 penetration to develop. This study reviews the advantages and disadvantages of the techniques used for injecting CO 2 into subsurface reservoirs and the methods adopted in attempts to control CO 2 mobility. Recently developed methods are leading to improvements in CO 2 -EOR results. In particular, the involvement of nanoparticles combined with surfactants can act to stabilize CO 2 foam, making it more effective in the reservoir from an EOR perspective. The potential to improve CO 2 flooding techniques and the challenges and uncertainties associated with achieving that objective are addressed.

“…Aqueous foam is a disperse form of gas in a continuous liquid [ 1 ]. Foam is widely used in food [ 2 ], foam flotation [ 3 ], firefighting [ 4 , 5 ], and petroleum industries [ 6 , 7 , 8 ] because of its high fluidity, excellent rheology, low water consumption, and reduced formation damage [ 9 , 10 , 11 ]. Aqueous film-forming foam (AFFF) is currently recognized as the most widely used extinguishing agent in liquid fuel fires, as it has excellent foam stability and film-forming ability provided by fluorocarbon surfactants and hydrocarbon surfactants [ 12 , 13 , 14 , 15 , 16 ].…”

The combination of nanoparticles (NP) and surfactant has been intensively studied to improve the thermal stability and optimize the performance of foams. This study focuses on the influence of silica NPs with different concentration on the thermal stability of gel foams based on a mixture of fluorocarbon (FS-50) and hydrocarbon (APG0810) surfactants. The surface activity, conductivity, viscosity, and foaming ability of the APG0810/FS-50/NPs dispersions are characterized. The effects of NP concentration on coarsening, drainage, and decay, as well as of the gel foams under thermal action, are systematically studied. Results show that NP concentration has a significant effect on the molecular interactions of the APG0810/FS-50/NP dispersions. The surface tension and conductivity of the dispersions decrease but the viscosity increases with the increase in NP concentration. The foaming ability of APG0810/FS-50 solution is reduced by the addition of NPs and decreases with the increase in NP concentration. The coarsening, drainage, and decay of the gel foams under thermal action slow down significantly with increasing NP concentration. The thermal stability of the gel foams increases with the addition of NPs and further increases with the increase in NP concentration. This study provides a theoretical guidance for the application for gel foams containing NPs and surfactants in fire-extinguishing agents.

“…The research on foam stabilization of silica particles mostly focused on the interaction between cationic surfactants and hydrophilic particles ( Hurtado et al, 2018 ; Ren et al, 2022 ), but in the application of foam oil displacement in oil fields, due to the existence of bentonite in the geological formation ( Zhao et al, 2020 ), the application of cationic surfactants was limited.…”

The world is rich in heavy oil resources, however, the recovery difficulty and cost are both higher than that of conventional crude oil. To date, the most common method of recovering heavy oil is steam flooding. However, once the steam breaks through the geological formation, gas channeling readily occurs, which leads to a rapid decrease of the steam drive efficiency. To improve the swept volume of steam in the geological formation, a series of hydrophobic silica particles for stabilizing foam was synthesized. This kind of particles used hydrophilic nano silica particles as reactant. Hydrophobic groups with cationic long carbon chains were grafted onto the surface of hydrophilic silica particles by synthetic silane quaternary ammonium salt. When the quantity of silane quaternary ammonium salt used in the modification reaction is different, the product had various degrees of wettability. The hydrophobic particles with the contact angle closest to 90° had the best foam stabilization effect on the betaine zwitterionic surfactant LAB. For LAB solution with mass fraction of 0.3%, the half-life of foam was extended into 160% when the mass fraction of particles was 0.5%. The higher the gas-liquid ratio, the better the plugging effect of foam agent with hydrophobic particles presented in porous media. The adsorption test of hydrophobic particles indicated that hydrophobic particles improved the stability of foam liquid membrane by improving the adsorption capacity of surfactant molecules. The thermal stability of hydrophobic silica particles exceeded 200°C, and the good foam stability made it a potential additive for foam oil displacement in high-temperature geological formation.
