Hydro Ethyl Cellulose
It is a non ionic, acid soluble, modified starch
Application & Uses
Commonly used as a brine viscosifier for completion and workover fluids where suspension (gelation) character is less important, HEC functions in various brines, including calcium, zinc chlorides, bromides, and monovalent analogues.HEC is used for gravel-packing, spacers, and pills. The
polymer exhibits negligible effects on producing formations, and various chemical agents can break the polymeric structure to facilitate complete removal.
