INHIBISAL ULTRA® CS-135
DESCRIPTION

Inhibisal Ultra CS-135 is a water miscible liquid additive containing choline chloride, which is used as a substitute for potassium chloride in drilling, workover, completion, and fracturing fluid applications.   Inhibisal Ultra CS-135 is typically used in amounts ranging from 0.5 to 10.0 gal per 1,000 gal (0.5 to 10.0 L/m3) depending on the amount of potassium chloride being replaced, the quantities of shale and clay present in the well bore, and the operation being performed.  A concentration of 1.0 gal per 1,000 gal (1.0 L/m3) of Inhibisal Ultra CS-135 will provide an equivalent to 2.0% potassium chloride.  Inhibisal Ultra CS-135 packaging can be customized to meet specific requirements.
