INHIBIDRILL is a cationic multivalent clay/shale inhibitor. INHIBIDRILL is primarily used as a clay/shale inhibitor in water-based fluids. It is also used in water flood clay stabilization.
NOTE: Additions to a bentonite system will cause flocculation; bentonite must be prehydrated prior to addition. Using bentonite with INHIBIDRILL will cause product
depletion. The use of INHIBIDRILL in bentonite-based fluids is not recommended. Highly
reactive clays/shale will require higher maintenance treatment, again due depletion.
pH should be maintained at below 10.5.

It is recommended to conduct Capillary Suction or Core Flow Testing to determine the
optimum INHIBIDRILL concentrations.
