Abstract: Abstract In this study, a gemini zwitterionic viscoelastic surfactant with a sulfonic group, named VES-S, was synthesized. The surface activity properties of VES-S were found to show an ultra-low sensitivity to the salt concentration compared…

Abstract: HYPOTHESIS The relaxation time in viscoelastic surfactant solutions is a function of temperature, salt/surfactant concentrations, resting conditions, as well as shear frequency. The simplistic assumption of a single and constant relaxation time is not representative…

Abstract: Abstract A novel fracturing fluid (NAF) comprising of self-synthesized β-cyclodextrin-functionalized hydrophobically associative polymer (HMPAM) and viscoelastic surfactant (VES) was developed. The apparent viscosity of NAF was several times more than that of HMPAM and VES…
