“…The thinning of liquid lamellae and motion in the foam structure due to gravity drainage may lead to the sudden rupture of foam films (Schramm and Wassmuth, 1994) In general, any factor that reduces the rate of film drainage may also increase the lifetime of the foam. Reduced drainage and improved foam stability have been reported for several polymer/gel-surfactant combinations (Aarra et al, 1997;Azdarpour et al, 2013;Cohen-Addad et al, 1994;Phillips et al, 1987;Rohani et al, 2014;Zhu et al, 1998Zhu et al, , 2004. In addition, some mixtures of different types of surfactants enhance foam stability, possible due to the formation of a viscous surface layer (Langevin, 2000;Ross and Morrison, 1988;Schmidt, 1996).…”

The last ~4.5 years have been the most exciting and challenging period in my life so far. I want to use this opportunity to thank at least some of the people who have supported me in one way or another during this period. I wish to express my gratitude to my supervisor Dr. Morten G. Aarra; thank you for sharing your knowledge with me, for your personal encouragement, and for the many good discussions. My co-supervisor, Professor Arne Skauge, deserves a special thank as well; thank you for scientific advice and assistance throughout the work, for giving me the opportunity to participate as a Master and PhD student at Uni CIPR, and for offering me a permanent position thereafter. Acknowledge goes to Hege Ommedal for her support as PhD-coordinator at the department of Chemistry. I am also thankful to other past and present colleagues at Uni CIPR who have made this time

“…It is reasonable to expect that there is a threshold SDS concentration above which no significant increase in apparent viscosity could be observed. 37,38 Unlike the anionic SDS, the μ a of the CO 2 foam was not affected much by either the nonionic Ecosurf or the cationic DTAB. As the concentration of the surfactant increased up to 0.03%, the μ a of the CO 2 foam slightly increased from 5.8cp to around 6.5cp, displaying a sharp contrast with the case of the negatively charged SDS.…”

The goal of this study is to experimentally investigate the stability and rheological behavior of supercritical CO2 foam in the presence of nanosilica, a surfactant, and a polymer. First, three types of surfactants with different charges were used to generate CO2 foam together with nanosilica under supercritical conditions. The anionic, cationic, and nonionic surfactants each interacted differently with the negatively charged silica nanoparticles (NPs). Owing to its yielding the highest apparent viscosity with nanosilica, the anionic sodium dodecyl sulfate (SDS) surfactant was selected to generate nanosilica-stabilized foam with a polymer to further enhance its apparent viscosity. Second, the thermal resistance of nanosilica-SDS-stabilized CO2 foam was assessed in terms of foam apparent viscosity and stability under reservoir conditions with higher temperatures. Finally, supercritical CO2 foams were generated with a combination of nanosilica, SDS, and 2-hydroxyethyl cellulose (HEC) polymer with various concentrations at different temperatures. Results show that the anionic SDS surfactant yielded higher apparent viscosity and foam stability with nanosilica. An optimal SDS concentration was expected, beyond which no significant improvement on foam apparent viscosity could be found judging from the trend of the experiment result. The cationic surfactant dodecyl trimethylammonium bromide (DTAB) and nonionic Ecosurf EH-9 surfactants performed similarly and did not yield any significant improvement in foam apparent viscosity. The addition of the polymer not only yielded higher apparent viscosity but also improved the thermal resistance of the NP-SDS-HEC-stabilized CO2 foam. For each combination of additives, higher temperatures have consistently shown its undermining effect on foam apparent viscosity and stability. However, the combination of the NP-SDS-HEC CO2 foam system has shown great improvement in foam performance compared to the case of foam stabilized with nanosilica alone. The results of this research suggest a compatibility check among additives within the fluid before further optimization work to ensure synergy among these additives. An interactive mechanism among these additives was proposed, which can explain the experimental results consistently. The results of this research can be used as guidance toward the performance optimization of nanosilica-stabilized CO2 foam for fracturing applications.

“…They discovered that BSA reduced the foaming ability of surfactant solutions but increased the foam stability. The effect of the water-soluble polymer partially hydrolyzed polyacrylamide (HPAM) on the foaming ability or the foam stability of different surfactant solutions was reported by Ahmed et al, Azdarpour et al, and Xu et al [36][37][38]. Experimental results showed that HPAM could improve the foaming ability and foam stability of surfactant solutions.…”

Aqueous foam is widely used in fire extinguishing and dust suppression technologies. Improving the foaming ability is the key to reducing the added concentration of foaming agents as well as the economic cost. In this work, the effect of a water-soluble polymer (polyvinyl alcohol, PVA) on the foaming ability of anionic surfactant (sodium dodecyl ether sulfate, SDES) was studied by an experiment and molecular dynamics simulation. The experimental results showed that PVA greatly improves the foaming ability of SDES solutions when the surfactant concentration is less than 0.1%, which is attributed to the fact that the polymer can enhance the stability of bubble films and reduce the bubble rupture rate during the foam generation process. The simulation results indicate that PVA can enhance the hydration of surfactant head groups and contribute to the formation of a three-dimensional hydrogen bond network between surfactants, polymers, and water molecules, thus greatly improving the stability of bubble liquid films. The above results suggest that water-soluble polymers can be used to improve the foaming ability of surfactant solutions by enhancing the bubble film stability, which is beneficial as it reduces the added concentration of foaming agents in aqueous foam applications.
