“…Zhu et al 17 pointed out that stimulusresponsive WLM-CO 2 foam systems have the advantages of reversibility and controllability with outstanding application in plugging systems that could strive for increased production for oilfield development. Xu et al 18 combined molecular dynamics simulations to investigate the effect of different structures of surfactant (made in the laboratory from 1-bromopropane and 3-chloro-1-propanol) on responses to CO 2 and maximize the potential of stimulus-responsive WLM-CO 2 foam. Their results revealed that the number of hydroxyl groups possessed by the CO 2 -triggered surfactants could severely affect the interfacial tension.…”

Foam flooding is an important tool for reservoir development. This study aims to further investigate the interaction between stimulus-responsive wormlike micelle (WLM)-CO2 foams and crude oil. We performed micromorphology experiments as our major studies and used molecular dynamics simulations as an auxiliary tool for interfacial analysis. We utilized foam generation, liquid separation, and defoaming as the entry points of experimental research and energy as the quantitative assessment index to investigate the dynamic process of the action of different oil contents and oil phase types in a DOAPA@NaSal-H+ foam system. We also examined the role of NaSal in the generation and development of the foam system. Results indicated that the law of crude oil’s effect on foam could be summarized as “low contents are beneficial and high contents are harmful.” In addition, although the DOAPA@NaSal-H+ foam system has high compatibility for saturated and aromatic hydrocarbons, it is highly suitable for application in reservoir environments with relatively high asphaltene and resin contents. Through combined experimental and simulation approaches, we clarified the law governing the stability of the DOAPA@NaSal-H+ foam system in different oil-containing environments, identified the key role of NaSal, and provided a reference for the targeted application of the DOAPA@NaSal-H+ foam system in different oil reservoirs.

“…10 Among them, CO 2 response stands out from many methods because of its unique advantages. 11 The research work on WLM-CO 2 foams is gradually being carried out. Su et al 12 used two foam systems such as sodium octadecyl sulfate (C 18 SNa) to study the smart worm micelles that can be triggered by CO 2 and found that the viscosity of the WLM foam system under CO 2 stimulation is reversible.…”

The reservoir environment is complex and variable, and the foam itself is a thermodynamically metastable system. Therefore, the influence of a high-temperature and high-salt reservoir environment on the stability of foams has not been extensively studied in the field of foam flooding. In this study, the influence of high-temperature and high-salt oil reservoir conditions on the stability and stability mechanism of wormlike micelle (WLM)-CO 2 foam systems was explored using foam volume, foam half-life, liquid separation half-life, and foam coarsening behavior as the performance indexes. This goal was achieved by characterizing the foam stability, setting a series of temperatures and salinity in the environment where the foam system is located, and applying statistical methods to intuitively recognize the foam and evaluate the foam effect. In addition, the theory of rheology was used to measure WLM-CO 2 foam system's apparent viscosity and the modulus of energy storage and modulus of loss of foams, and the foam effect was evaluated indirectly. The results showed that the higher the temperature of the WLM-CO 2 foam in the experimental temperature range, the worse the foam stability was. The effect of salinity on the stability of WLM-CO 2 foams is "slightly synergistic, excessively antagonistic". This paper systematically explored the stability law of WLM-CO 2 foams under high-temperature and highsalt reservoir conditions from the microcosmic level and analyzed the attenuation mechanism of the foam by innovative use of rheological theory as to provide a more comprehensive theoretical guidance for the practical application of the WLM-CO 2 foam system in enhanced oil recovery.
