Fluid Suspension: It aids in suspending solid particles, such as cuttings, in the drilling mud. This prevents settling and blockages in the wellbore, ensuring efficient drilling operations.

Shear-Thinning Properties: Xanthan gum exhibits shear-thinning behavior, meaning it becomes less viscous under shear forces, like when pumped through the drill pipe. This property allows for easier pumping and circulation of the drilling fluid while maintaining viscosity when static.

Temperature Stability: It offers good temperature stability, making it suitable for drilling in various environmental conditions, including high-temperature reservoirs.

Fluid Loss Control: Xanthan gum helps reduce fluid loss to the formation, minimizing damage and maintaining well integrity during drilling.

Rheological Properties: It imparts desirable rheological properties to the drilling fluid, ensuring that it flows consistently and behaves predictably downhole.
