“…After the surfactant concentration reaches the critical entanglement concentration, the flexible wormlike micelles are entangled, adhered, and even fused under the action of the applied shearing force and molecular thermal motion, forming a kind of supramolecular three-dimensional network structure. The viscosity and viscoelasticity of the solution become more and more obvious, forming the viscoelastic fluid (Dreiss, 2007;Moore et al, 2018;Pal et al, 2018b;van Santvoort and Golombok, 2015;. From this perspective, the viscoelastic surfactant wormlike micelle solution behaves similarly to the polymer solution.…”

Although new energy has been widely used in our lives, oil is still one of the main energy sources in the world. After the application of traditional oil recovery methods, there are still a large number of oil layers that have not been exploited, and there is still a need to further increase oil recovery to meet the urgent need for oil in the world economic development. Chemically enhanced oil recovery (CEOR) is considered to be a kind of effective enhanced oil recovery technology, which has achieved good results in the field, but these technologies cannot simultaneously effectively improve oil sweep efficiency, oil washing efficiency, good injectability, and reservoir environment adaptability. Viscoelastic surfactants (VES) have unique micelle structure and aggregation behavior, high efficiency in reducing the interfacial tension of oil and water, and the most important and unique viscoelasticity, etc., which has attracted the attention of academics and field experts and introduced into the technical research of enhanced oil recovery. In this paper, the mechanism and research status of viscoelastic surfactant flooding are discussed in detail and focused, and the results of viscoelastic surfactant flooding experiments under different conditions are summarized. Finally, the problems to be solved by viscoelastic surfactant flooding are introduced, and the countermeasures to solve the problems are put forward. This overview presents extensive information about viscoelastic surfactant flooding used for EOR, and is intended to help researchers and professionals in this field understand the current situation.

“…Previous studies have shown that analysis of the low-Q upturn can readily report on the structural characteristics of the solution. [64][65][66] Here, a I p Q b power law was fitted to the low-Q region to extract the relatively large-scale structural features of the solution. At all temperatures tested here, the b exponent systematically changes with increasing Na 2 SO 4 concentration as shown in Fig.…”

“…It was shown that for both surfactant systems, the samples that did not contain any HA were low viscosity, Newtonian systems. This is understandable given that HA has the ability to help build viscosity and the surfactants alone typically have lower viscosities at a concentration of 10%, confirmed by Pingali, Benhur and Amin, as well as Moore et al [17,18]. As the concentration of HA increased in both systems, they become non-Newtonian, shear-thinning and high viscosity samples.…”

“…When chitosan is added to the system, the repulsive interactions allow for entanglements to occur and cause the viscosity to increase. The rheological properties of APG were observed by Moore et al and it was discovered that both longer APG chains and higher concentrations were able to produce higher-viscosity samples [18]. It is also important to note, even if original samples do not demonstrate high viscosities, the ability to build viscosity in systems is a desirable property.…”

Recently, consumers have become invested in more natural and sustainable ingredients contained in personal care products. Unfortunately, cationic surfactants are still heavily relied on as primary conditioning agents in products such as conditioning shampoos because of their ability to cling well to the negatively charged surface of hair follicles. Additionally, sulfates are utilized as cleansing agents because they are highly effective and low cost. The objective of this study is to find a more sustainable formulation for a conditioning shampoo without compromising the desired wet combing, rheological, and surface activity properties. The systems which were investigated contained hyaluronic acid (HA) at a variety of molecular weights and concentrations, in combination with a surfactant, either acidic sophorolipid (ASL) or alkyl polyglucoside (APG), and varying the presence of sodium chloride. A Dia-stron was utilized to test the wet combing force, a rheometer recorded the viscosity at various shear rates, and a tensiometer measured the surface tension of the samples before a visual foaming study was conducted. Molecular weight and concentration seemed to have a large impact on wet combing force, as well as rheology, with the largest molecular weight and concentration producing the lowest friction coefficient and desired rheological profile. The addition of a surfactant significantly aids in the reduction in surface tension and increased foamability. Therefore, the optimal system to achieve the largest reduction in wet combing force, large viscosity with shear-thinning behavior, and relatively low surface tension with decent foaming is composed of 1% HA at 800 kDa, 10% ASL and 1% NaCl. This system shows a viable sulfate-free and silicone-free option that can achieve both conditioning and cleansing.
