“…Extensive studies have been conducted on the stability of foam, and effective stability factors include gravity, Marangoni effect, disjoining pressure, capillary pressure, and the presence of oil. [1][2][3][4][5][6] Gravity: One of the most influential factors in foam stability is liquid film drainage, which ensues from gravity force. The liquid flows from the film to the plateau border during this phenomenon.…”

The effect of the existence of nanoparticles on foam stability, foamability, and the oil recovery factor (RF) has been studied experimentally, and influential phenomena and mechanisms have been examined. A sequence of experiments, including, ‘foam bulk‐static experiments’, ‘surface tension (ST) measurements,’ and ‘micromodel foam flood,’ were designed and then implemented to study the foam behaviour in two foam systems: (1) anionic‐nanoparticles + cationic‐surfactant and (2) anionic‐nanoparticles + anionic‐surfactant. This study provides a comprehensive insight into the mechanisms affecting the stability of nanoparticle‐stabilized foam. Also, despite previous studies, the effect of Marangoni flow on nanoparticle‐stabilized foam has been discussed briefly. Results show that the interactions of effective mechanisms work differently in the two series. In the like‐charge system, surfactant molecules accumulate in the interface of lamellas due to repulsive forces; therefore, stability and foamability improve as surface tension and molecular diffusion reduce. Additionally, Marangoni flow restitutes the negative impact of gravity drainage. In the unlike‐charge system, observations illustrate that nanoparticles reach the interface. The presence of nanoparticles at the interface increases detachment energy significantly, and as a result, the stability is boosted. The accumulation of nanoparticles in the interface changes it to a solid‐like surface with limited diffusibility and viscosity. Although Marangoni flow is lost, reducing molecular diffusion improves foam stability. Flooding tests show that foam stability increment improves sweep efficiency at near‐wellbore areas even when foamability is weak. Finally, it can be claimed that in the unlike‐charge system, the sweep efficiency and foam stability increase to a greater extent.

“…Although both mechanisms are within the mechanism of capillary pressure, capillary adsorption utterly depends on the surfactant formulation in comparison to the capillary snap-off. Two-dimensional presentation of foam system are being graphically depicted in Figure 1 (Jones et al, 2016a(Jones et al, , 2016bKapetas et al, 2016Kapetas et al, , 2017Khoshnevis et al, 2017;Li et al, 2006;Razmjoo et al, 2017).…”

Foam flooding is considered as one of the beneficial chemical enhanced oil recovery techniques to increase the value of gas viscosity and thereby, the efficiency of the produced oil would be improved dramatically rather than other methodologies. The objective of this extensive study is to determine a suitable injectivity model for one of the heterogeneous sandstone reservoir in which hydrolyzed polyacrylamide concentration in the solution foam has the most recovery factor. To do this, the results of laboratory investigation and simulation analysis are taken into consideration in different injectivity scenarios to obtain the more efficient scenario. Consequently, higher concentration of hydrolyzed polyacrylamide in the foaming agent, the high volume of oil has been produced after 10 years of producing. Furthermore, by selecting three cores from the three wells in this field, it is clarified that, owing to the increasing the volume of foam in the injectivity fluid, the pressure drop increased dramatically and subsequently has leaded to produced more oil volume.
