1. n. [Drilling Fluids]
A cellulose polymer that contains anionic carboxymethyl and nonionic hydroxyethyl groups added by ether linkages to the OHs on the cellulose backbone. This polymer has seen limited use in drilling mud, but more use in brines and completion fluids.
Alternate Form: carboxymethyl hydroxyethylcellulose, CMHEC
