HYDROXY ETHYL CELLULOSE
(EXTRA HIGH VISCOSITY, HEC-EHV)
Description:
HEC (EHV) is a nonionic, water soluble hydroxy-ethyl-cellulose, Extra High Viscosity and is used as viscosifier in colloidal base for ultra-low solids polymer mud.
Due to the nonionic character, it remains stable at high calcium chloride concentrations. It is also prevents dispersion of drill cuttings and stabilizes water-sensitive shale.
