Drillvis L Premium is a high viscosity Xanthan gum biopolymer suspended in liquid Ester. It could be used in most type of water-based fluids as rheology modifier. Comparing with powder Xanthan gum, it's easy to handle ,it can be solve in water easily even without high speed stirring,won't be disturbed with dust . It is well known for  it's ability of high viscosity build at low shear rates, excellent carrying and suspending characteristics. This type of polymer is unique when compared to most other polymers in oilfield drilling,workover and completion applications.
