“…Despite these favourable properties, foam is not thermodynamically stable and its physical structure can break down easily when two bubbles approach each other. This collapse in the structure of foam happens as liquid film between adjacent bubbles undergoes thinning, and as a result liquid film can rupture [25][26][27]. Various methods have been proposed to improve foam stability, such as increasing surfactant concentration, mixing different types of surfactants, and addition of co-surfactants and polymers to foaming agents.…”

Gas injection and especially CO2 flooding has been applied in many oil reservoirs globally to increase oil recovery factor in addition to its environmental friendly aspects. However, difference between fluid viscosities and densities, can cause interface instability where gas override and fingering may expedite gas breakthrough. Different types of foam have been proposed to improve interface stability. Yet, a major uncertainty is interaction of foam with natural reservoir particles which may improve or downgrade the performance and stability of foam. In this study we examined foam stability through solid-fluids interactions between solid particles of hydrocarbon reservoirs and aqueous foam. We tested five common reservoir particles of calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate and iron oxide with different surfactant and particle concentrations. It is found that stability of foam in the presence solid particles is a function of density, shape, size, and wettability of particles where monolayer, bilayer of network or particles stabilise foam lamella or rupture foam structure. Results show that solid particles of calcium carbonate, barium sulfate and strontium sulfate enhance the thermodynamic stability of foam. This is due to the distribution of semihydrophilic solid particles, which form mono-and multi-layers of particle chains in foam lamellae and plateau borders. On the other hand, solid particles of iron oxide and calcium sulfate destabilise foam where particle swelling, adsorbed surfactant solution and settlement into liquid phase due to their high densities were observed. The results suggest that a comprehensive study of liquid and solid interaction is critical in design of any foam for enhanced oil recovery processes.

“…This region could be seen as the outcome of the combination of two phenomena. The first one was the decrease of the liquid volume due to foam drainage under the gravity and capillary effects, and the second one was that the increase of bubble size due to coarsening and coalescence accelerated foam drainage (Lioumbas et al, ), which can also be found in Fig. 6.…”

“…In recent years, a large number of studies concerning foam properties have dealt with single‐surfactant systems (Bournival et al, ; Carey and Stubenrauch, ; Gupta et al, ; Lioumbas et al, ) and mixed systems such as alcohol–surfactant mixtures (Erol et al, ; Karakashev and Nguyen, ), surfactant–surfactant mixtures (Carey and Stubenrauch, ), polymer–surfactant mixtures (Dey et al, ; Mitrinova et al, ; Ropers et al, ), and protein–surfactant mixtures (Alahverdjieva et al, ; Maldonado‐Valderrama and Langevin, ). Many studies have shown that free drainage and bubble size variations due to coarsening are closely connected.…”

Although foams stabilized by surfactants have been the subject of massive investigations and great achievements were made over the past few years, many questions concerning their properties are still not well understood. The aim of this study is to examine the effect of the cetyltrimethylammonium bromide (CTAB) concentration on the foam properties and illustrate the interaction between liquid drainage and bubble size evolution. Experiments were carried out at varying CTAB concentrations ranging from 0.1 to 5.0 times the critical micelle concentration (CMC), where the variation of the liquid content of foam and bubble size was simultaneously determined using a commercially available FoamScan device. The results showed that the foam properties (both foamability and foam stability) of CTAB were largely dependent on the surfactant concentration when concentrations c < CMC but this effect did not scale linearly with concentration. When c ≥ CMC, both foamablity and foam stability were nearly concentration independent, while the latter showed a small decrease due to the formation of micelles. In addition, the correlation between free drainage and bubble size evolution indicated that the increase of bubble size could indeed enhance the foam drainage.

“…As shown in Fig. a, the foam decayed quickly at the initial stage, which originated from the collective factors of drainage, coarsening, and coalescence of foam (Lioumbas et al, ; Wang et al, ). After a certain time, the foam volume reached a plateau as the above‐mentioned process slowed down in the sealed container.…”

“…The acceleration of the foam size enlargement might be because of foam coarsening or coalescence. It was hard to distinguish the two factors (Lioumbas et al, 2015;Wang et al, 2016a), but both were related to the interfacial film intensity (Emile et al, 2009;Małysa, 1992). To explore the variation in foam film elasticity, the texture analyzer measurement was taken (Deng et al, 2016;Hu et al, 2012;Qi et al, 2018) as shown in Fig.…”

In the wide application of foam products, the effect of oil additive on foam property is a critical issue that has gained increasing attention; the effect on foam induced by various flavor oils is still a puzzling question, and relative study is rare. In this article, a series of typical flavor oils were studied for their effects on the foam properties of sodium dodecylsulfate. Measurements of foamability, foam stability, foam elasticity, and surface activity were taken; meanwhile, molecular dispersion and interfacial arrangement behavior of surfactant and oil molecules were explored by molecular dynamics simulation. Through a combination of macroscopic phenomenon and microscopic information, how flavor oils with different chemical structures affected the foaming properties of surfactants was demonstrated, and an evaluation scheme for predicting the level of influence on foam properties by different flavor oils was constructed. This investigation may help better understand the role of flavor oils in foam systems and provide a theoretical foundation for optimizing the application of flavor oils in relevant industries.
