Common chemical additives in ,fracturing fluid, are often surfactants [7,34,36,37,38]. Generally, they are intended to increase the viscosity of ,fracturing fluid, to allow it to propagate within the target formation. An anionic surfactant that is added in ,fracturing fluid, mixture is Internal Olefin Sulfate (IOS) [34].
