BORZAN® is a true biopolymer designed for use in vertical and horizontal drilling applications where conventional bentonite based drilling fluids may not be desirable. BORZAN®’s highly concentrated xanthan gum formulation allows for less material to be used than most other bio-polymers. Normal application rates are only 3 to 3½ pounds per 100 gallons to achieve a 45 second Marsh Funnel viscosity.
