CMC, a modified cellulose polymer used in drilling fluids.

abbr: carboxymethylcellulose.

carboxy methyl cellulose.

materials that reduce the fluid loss from a wellbore fluid. May include Bentonite clays, lignite, CMC, etc.

n: the CMC product with high degree of polymerization ,high molecular weight and viscosity ,mainly used as adhesion promoter

n: the derivant of cmc

n: no colour, clear liquid,soluble to water,ethanol and aether,the main solvent that produces CMC or HEC.

an uncrosslinked polymer gel. Typical polymers are guar, HPG, CMC, HEC, etc.

n: a degignation given to any type of mud where high performing additives e.g.,cmc, have been partially or wholly substituted for commercial or natural clays. For comparable viscosity and densities (weighted with barite),a low-solids mud will have a lower v

n: CMC strain that made of short fibre, it has low viscous and degree of polymerization(D.P).

n: CMC strains that its degree of polymerization is medium, and made of wood pulp.
