Bulk foam stability and rheological behavior of aqueous foams prepared by clay particles and alpha olefin sulfonate
TL;DR: In this article, the authors examined the properties of the aqueous foams prepared by alpha olefin sulfonate (AOS) and clay particle dispersions using foam stability and rheological behavior analysis and found that the AOS/clay dispersions have a synergistic effect on the stability of foam and the foam stability increases with the clay particle concentration.

Systematic investigation of the physicochemical properties of eco-friendly biobased anionic-nonionic surfactants for enhanced oil recovery
TL;DR: In this article, a series of biobased anionic-nonionic surfactants were used to evaluate their physicochemical properties for predicting the effectiveness in chemical enhanced oil recovery (EOR) applications and the results indicated that the hydrophobic carbon chain length and oxyethyl groups in surfactant molecular structure effected on the surface tension, salt tolerance, adsorption amount on the quartz sand and interfacial tension of the lignin polyether sulfonates.

Synthesis of Surfactants from Alkali Lignin for Enhanced Oil Recovery
TL;DR: In this paper, the effects of amination conditions, including the ratio of raw materials, amination reagent, temperature, and reaction time, on nitrogen contents and surface tension of the surfactants were investigated.

Synthesis and Physicochemical Investigation of Anionic–Nonionic Surfactants Based on Lignin for Application in Enhanced Oil Recovery
TL;DR: A series of eco-friendly anionic-nonionic surfactant lignin polyether sulfonates (LPES) based on alkali Lignin from the paper-making industry was prepared through alkoxylation, allylation and sulfonation as mentioned in this paper.
