Foam is one of the most cost-effective means of solving the drawbacks associated with the process of gas injection. The presented work is focused on probing the impact of oil saturation on CO2 foam generation and its stability in the presence of high temperature and high salinity conditions. In this work, initially a texture-implicit local equilibrium model is used for parametric matching of a core flooding experiment conducted in the absence of oil. Once the foam parameters are calculated and tuned, the designed model is later up-scaled and studied with the inclusion of oil. The key objective is to study the effect of miscibility on the foam displacement front and the degenerating effect instilled by the residual oil saturation on the stability of foam. Different field scale models are designed and compared to validate the observed effect and hypothesis. The results of this work suggests that during CO2 foam flooding the oil saturation has a profound effect on oil recovery especially when CO2 is in an immiscible state with oil when compared with the miscible state.

“…159 Furthermore, foam formation generally increases up to a certain concentration, called the CMC, and after that, there is very little effect on foam formation. 160,161 The concentration of the foaming agent also has an influence on the viscosity of the produced foam. 159 According to studies, the coefficient of viscosity of foam increases as the surfactant content increases.…”

Global demand for energy is increasing day by day rapidly as a result of the population, industrial, and economic growth of developing countries, especially in emerging market economies. Hence, to meet this growing and continuing global crude oil demand, innovative enhanced oil recovery (EOR) techniques are required to emerge, and currently, implemented techniques need to be revisited and optimized to recover more residual oil trapped in the reservoirs. Among different chemicals, foam has good mobility control in the oil recovery method. Nowadays, the study on the stability of foam is an utmost interest for petroleum engineers to find a way to obtain stable foam for application in EOR. In this review, the basics of foam and its preparations, properties, application, and some special applications mainly in the oil industry have been depicted to convey an idea of the degree of foam research in EOR. Basically, this review will provide a detailed discussion on the applications of foam in oil recovery and some short ideas that can be applied in the near future for nanoparticle (NP)-assisted stable CO2 foam flooding in EOR. Increasing the NP concentration initially improved foam stability because a higher number of NPs participated in strengthening the gas bubble and initially increased oil recovery as a result of the formation of more stable foam. The polymer-coated, nanoclay–surfactant-stabilized foam and surface-modified silica nanoparticles have exceptional foaming ability and foam stability at high temperatures, making them suitable for the production from heavy oil reservoirs. Some other nanoparticles, like Al2O3, ZrO2, TiO2, Fe2O3, and NiO, have also been used for enhancing foam stability by preventing liquid drainage from lamella. Also, NP-stabilized CO2 foam flooding can enhance oil recovery by 10–15% after secondary recovery by creating a more homogeneous gas front for better mobility control.

Recent studies on oil-foam interaction using different types of oil were limited to the aspect of alkane chain length, density and viscosity of crude oil. However, oil polarity toward foam stability to predict the significant variable of the foam half-life and its evaluation in macroscopic oil displacement is still elusive in literature. In this study, the effect of oil polarity on foam properties at bulk and macroscopic scales was investigated. The effect of electrolytes on surfactant foam stability was studied. Subsequently, the foam stability in the presence of polar and non-polar oil was determined. Thereafter, the macroscopic oil displacement efficiency of surfactant foam was evaluated. Finally, a multivariate linear regression analysis was used to predict the significant variable of the foam half-life. The results indicate that cocamidopropyl betaine (CAPB) foam had better stability under the influence of oil polarity, with a half-life decrease of 8% in hexane oil compared to 86% by sodium dodecyl sulfate (SDS). Moreover, SDS foam flooding recovered 10% additional oil compared to 5% CAPB foam. However, oil recovery in the presence of pyridine decreased oil recovery of SDS and CAPB foam flooding to 6% and 3%, respectively. Likewise, mobility reduction factor (MRF) of SDS foam decreased by 74% compared to 39% by CAPB foam. However, both MRF of SDS and CAPB foam drop drastically by 81% and 90%, respectively in the presence of pyridine compared to hexadecane. Finally, the multivariate regression analysis indicates that surfactant is the most significant variable with a P value below 0.0001. The R2 proportion of variation in the response attributed to this model was 0.81, with a root mean square estimation of 5.2386.
