Novel synthesized anionic gemini and monomeric surfactants bearing sulphonate group as petro-dispersing/collecting agents: Design, characterization and surface-active properties

Preparation and properties of new anion-active and non-ionogenic gemini SAM based on oxypropylated ethylenediamine and carbonic acids (stearic and olein)

“…Bu isə öz növbəsində su-hava sərhədində həmişə ciddi problemlər yaradır. Belə nazik neft təbəqələrini yalnız neftyığıcı və neftdispersləyici reagentlərin köməyi ilə kolloid-kimyəvi metodlardan istifadə edərək ləğv etmək olar [8]. Neftyığıcı reagentlərin köməyi ilə neft bir ləkə şəklinə salındıqdan sonra mexaniki yolla kənarlaşdırıla bilər.…”

Experimental and Computational Fluid Dynamics Investigation of Mechanisms of Enhanced Oil Recovery via Nanoparticle-Surfactant Solutions

“…Surfactant flooding is a popular enhanced oil recovery (EOR) method 4 to achieve lower residual oil saturation in a hydrocarbon reservoir by increasing the capillary number and the dominance of viscous forces over the capillary forces. 5 Surfactant molecules are surface-active agents that adsorb at the oil−water interfaces to decrease the interfacial tension (IFT) between fluids in the rock pores and alter the rockwetting state from a hydrophobic condition to a hydrophilic state. 6,7 However, surfactant molecules are easily lost on the rock surfaces, especially when the charges of the surfactants and rock surfaces are different, resulting in the increased cost of trapped oil mobilization via surfactant flooding.…”
