    POLY-BORE™ stabilizing agent is a free flowing, water-soluble, easy mixing, 100% active, dry granular polymer. POLY-BORE™ stabilizing agent is a very high molecular weight partially hydrolyzed polyacrylamide (PHPA) polymer. When mixed with fresh water, a small quantity of POLY-BORE™ stabilizing agent can provide a clear, solid-free, viscous borehole stabilizing fluid for use in drilled shaft, auger drilling, horizontal directional boring, trenching excavation and reverse circulation (RC) rotary drilling. POLY-BORE™ stabilizing agent is not designed to be used in conjunction with bentonite based fluids.

    Available in 14 lb. or 20 lb. pail.


    Build a clay-free boring fluid. Stabilize reactive clay and shale formations. Enhance core recovery in continous wireline coring operations.


    Can disperse easily with minimal shear. Efficient shale/clay stabilizer and viscosifier. Does not require solids control unit to clean the slurry. Helps maintain a stable and gauge borehole.

    It is recommended that Soda Ash (sodium carbonate) be added to the make-up water prior to the addition of POLY-BORE™ borehole stabilizing agent for reduction of excess calcium and pH adjustment.

    The above are generalized concentrations of POLY-BORE™ borehole stabilizing agent to be added to water-based drilling fluids. The ultimate usage concentration will be based on local geology, application and mixing efficiency. In the event that further information is needed, please refer to the Product Data Sheet or contact your local Baroid IDP representative.
