👉 The Sherman fluid, also known as the Sherman's red fluid, is a viscous, non-Newtonian fluid developed by American chemist William Sherman in the 1930s. It is a complex mixture of polymers and other additives that exhibit shear-thinning behavior, meaning its viscosity decreases under shear stress, making it easier to flow when agitated or poured. This property is particularly useful in industrial applications such as drilling fluids, where it helps reduce friction and carry cuttings from the wellbore while maintaining sufficient viscosity to prevent settling. The fluid's unique rheological properties make it an effective solution for optimizing drilling performance and efficiency in challenging geological conditions.
