Comparative study of natural chemical for enhanced oil recovery: Focus on extraction and adsorption at quartz sand surface. Petroleum. https://doi.org/10.1016/j.petlm.2022.01.007http://nur.nu.edu.kz/handle/123456789/6157In chemical enhanced oil recovery (CEOR), it is very important to utilize the excessive usage of chemicals. A great opportunity lies in adopting natural surfactants, since it is cheaper, ecosystem friendly, and less toxic than their counterpart synthetic surfactants. Despite the availability of natural surfactant sources, it is yet very early to decide on their applicability. Therefore, this research focuses on natural-saponin extracted from different raw materials available in the Middle East and their interaction with quartz-sand. A special focus was given to the adsorption isotherm models to describe the interaction with the reservoir rocks.enAttribution-NonCommercial-ShareAlike 3.0 United StatesType of access: Open Accessoil recoveryArticle
