Published in 2019 at "Chemical Engineering Science"

DOI: 10.1016/j.ces.2019.06.061

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… read more here.

Published in 2020 at "Chemical Engineering Science"

DOI: 10.1016/j.ces.2019.115370

Abstract: Abstract Recently, viscoelastic surfactant (VES) fracturing fluids have attracted wide attention because they are highly viscoelastic and environmentally benign. To optimize fracturing fluid formulations for coal reservoir conditions, 135 groups of VES fracturing fluids were… read more here.

Published in 2018 at "Journal of colloid and interface science"

DOI: 10.1016/j.jcis.2018.01.078

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… read more here.

Published in 2018 at "Journal of Petroleum Science and Engineering"

DOI: 10.1016/j.petrol.2018.04.032

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… read more here.
