POTASSIUM BROMIDE

Molecular Formula: KBr

CAS No: 7758-02-3

Description:

Potassium Chloride is a soluble salt that is an extremely efficient shale stabilizer when drilling hydro sensitive clays and shales. Inhibition is produced through exchange; the potassium ion enters between the individual clay platelets in the shale so that they are held together , thus eliminating entry of water from the drilling fluid.
