“…The viscosities of the homogeneous mixtures of the developed fluid in the presence of water at any definite mixing proportion are summarized in Table , which suggests low viscosity values. The reduction in viscosity value can be correlated to the transformation of the highly viscous lamellar structures into low viscosity spherical micelles . The increase in temperature at any mixing proportion caused a further decrease in viscosity, which facilitated the formation of spherical micelles.…”

A detailed study has been done on the phase behavior and rheologic al properties of Viscoelastic Surfactant (VES) bas ed fracturing fluids bearing lamellar liquid crystal structures that are developed from two surfactants (S DS and NaOA ) and three c o-surfactants (propan-2-ol, iso-amyl alcohol and 2-ethyl hexanol) in t he presence of clove oil as the organic phase and water as the aqueous phase. Lamellar liquid c rystals prepared from NaOA/2-ethyl hex anol/clove oil/water system demonstrated the best viscoelastic properties among all the developed fluids as it exhibited resistance to high temperature and shear conditions. Addition of alkali and nano-particles enhanced t he viscoelastic properties which were observed from static and dynamic rheological tests.

“…The viscosity and elasticity of the system increase due to the formation of ordered structures, which is influenced by surfactant properties and the presence of counterions. 63 VES fluids can be used for hydraulic fracturing at temperatures up to 200 °F, but the VES fluids that work at high temperatures are so expensive. Unlike polymer-based fluids, VES fluids do not create a filter cake on the formation face.…”

In the past decade, there has been significant attention given to the use of viscoelastic surfactants (VESs) as fracturing fluids in the stimulation of oil and gas reservoirs. One key challenge in VES utilization is improving the rheological performance of the fracturing fluid, ensuring stability and high performance under reservoir conditions characterized by high temperature and pressure. This enhancement aims to increase the wormhole propagation in underground reservoir porous media. To address this, different categories of additives have been employed to improve the performance of the fracturing fluid due to the formation of a filter cake and residual sediment particles after VES application. Nanoparticles have emerged as a particularly interesting additive with unique mechanical and chemical properties and characteristics. Studies have shown that the addition of nanoparticles improves the rheological properties of VES fluids, enhancing their stability and viscosity. Furthermore, nanoparticles have been found to increase the carrying capacity of the VES fluids for particles, making them more effective in different medium. This review provides a comprehensive investigation into the various factors influencing the performance improvement and rheological behavior of VESs by nanoparticles. These factors include surfactants, particle shape and size, temperature, salt concentration, pH, and effects of internal and external breakers. The study also includes a thorough review of the previous research on the use of nanoparticles to enhance the behavioral performance of the VESs. Finally, some fundamental recommendations have been proposed to fill the gap in the related research subject. This work is helpful to the oil and gas industries in applications of VES fluids to different fields, especially in the field of fluid dynamics in reservoir engineering.
