A liquid polymer that controls fluid loss, prevents clays from swelling and keeps tools clean by preventing bit balling. Wyo-Ben UNI-DRILL® is a unique proprietary liquid polymer designed for use in rotary drilling and horizontal directional drilling operations. It conditions drilling fluids to control fluid loss, prevent formation clays from swelling, and will keep tools clean by preventing bit balling. Unlike many commonly used polymers, UNI DRILL ® actually aids in the effective operation of solids control equipment by dropping silts and sands from the fluid. Similarly it is tolerant of brackish and harsh water conditions which adversely affect many other polymers. UNI-DRILL® is environmentally safe and non-fermenting.
