Abstract

L'invention concerne un liquide de fracturation renfermant un tensio-actif, plus précisément un tensio-actif cationique et un sel organique dans un milieu aqueux. Ce liquide peut être soumis à un moussage pour être utilisé dans des applications de fracturation, l'utilisation d'un tensio-actif moussant supplémentaire n'étant alors pas nécessaire.
