“…Another study has been done on the validity of walnut leaf extract in EOR. The result showed that the extract could reduce IFT from 11.18 mN/m to 2.54 mN/m . In other research, natural surfactant was derived from Eichhornia Crassipes and applied to check the product validity in EOR.…”

“…The common sources of this type of natural surfactant are mostly extracts of plants that contain saponin in their composition. Extracts from different plants have been reported in cEOR as natural surfactant, such as walnut leaf, Seidlitzia Rosmarinus, and mulberry leaf extract . However, the extracts of some plants have been reported to act as nonionic surfactants but the existing large amount of alkali metal such as Na + and Ka + in Rosmarinus extract and RNH 3 + Cl – radical in henna leaf extract forces them to behave as cationic surfactants. , Cationic surfactants from different natural plants have been reported that satisfy the EOR requirement with reasonable properties and acceptable CMC value.…”

Injecting surfactant by means of chemical enhanced oil recovery (cEOR) has acquired predominant attention in improving oil recovery by changing either fluid/rock and/or fluid/fluid interaction due to ion-pair forming and/or surfactant adsorption on the rock surface. As the main surfactant role in EOR, IFT reduction refers to adsorbing of surfactant molecules on the residual oil/water interface, which causes an increase in capillary number; as a result, trapped oil drops in porous media get free and start to move through the pore space toward the production well. The toxic nature, excessive cost, and environmental issues are the obvious limitations in applying the chemical surfactants in EOR, hence, looking for a less-expensive and eco-friendly type of surfactant has become a significant task to researchers to study the natural surfactant as an alternative to chemical surfactants. A deep understanding about the classification of natural surfactants, fabrication methods, and the difference between each class is crucial to propose a new plant-derived natural surfactant. This study tried to review up-to-date published studies related to the natural surfactant types and prepare a comprehensive catalog respective to natural surfactant that helps researchers with regard to future work in natural surfactant application in EOR. In addition, comparisons of each class performance and the impact of nanoparticles and the salinity on them in reducing IFT, altering wettability, and improving the recovery factor have been investigated. It had been concluded that natural surfactant can be produced from different plant parts (leaf, root, steam, fruit, and seed) based on the fabrication method. Natural surfactants synthesized from seed oil are stronger, compared with those extracted from the plant part (i.e., IFT reduction by 98%). Generally, injecting natural surfactants expressed low to high performance in improving the ultimate oil recovery from 2% to 40% original oil in place (OOIP).

Review on Potential Application of Saponin-Based Natural Surfactants for Green Chemical Enhanced Oil Recovery: Perspectives and Progresses

et al. 2023

Synthetic chemical surfactants deployed in the petroleum industry to improve oil recovery to meet growing global energy demand are described to have detrimental environmental impacts and are expensive. In recent times, the exploration of saponin-rich plants as a substitute for environmentally threatening synthetic surfactants has garnered significant interest from researchers. Saponin-based natural surfactants (SBNSs) are nontoxic, biodegradable, and possess desirable properties for use in the oil and gas industry. This paper reviews the potential application of saponin-based natural surfactants in enhanced oil recovery processes that coincide with the interests of the United Nations' Sustainable Development Goal 7 for Affordable and Clean Energy. We reviewed the mechanisms of saponin-based natural surfactants in enhanced oil recovery (EOR), surfactant adsorption, and the recent advances in utilizing saponin-based natural surfactants for EOR purposes. We also provided a comprehensive analysis of the impact of salinity and temperature on the performance of SBNSs. Moreover, the study also presented the economic feasibility and limitations of SBNSs for field enhanced oil recovery applications. We identified that a good number of SBNSs can withstand harsh reservoir conditions, optimize interfacial tension by as high as 95.82% (although not to ultralow levels), and alter rock wettability from hydrophobicity to hydrophilicity, thereby reducing the contact angle by 3.64% to 87.5%. SBNSs also successfully yielded a high incremental oil recovery factor of up to 36% in the postsecondary recovery stage. The advent of techniques, such as alkali incorporation and nanotechnology, support the achievement of ultralow interfacial tension, mitigation of surfactant adsorption, and oil recovery improvement. Future studies can adopt the recommendations outlined in this study to minimize uncertainty in the utilization of SBNSs and enhance their design for "green" chemical enhanced oil recovery applications.
