CMC
CMC — Carboxymethyl Cellulose
Cellulose ether used as a fluid-loss additive and viscosifier in water-based drilling fluids, available in LV and HV grades.
Application
Freshwater and low-to-medium salinity water-based muds. Grade selection depends on required viscosity, filtration control and salt tolerance.
Technical characteristics (quality certificate)
Typical values as stated on a mill quality certificate (passport) for a standard commercial grade. Actual lot values are confirmed in the COA / TDS for the selected manufacturer.
API fluid loss (max)
Per functional class / grade
API RP 13B-2 / API 13A
Viscosity grade
LV / MV / HV per TDS
API RP 13I
Loss on drying
≤ 10%
API 13A / Manufacturer TDS
Reference profile for orientation. For each supply we confirm grade, origin and certificate data against your specification, well conditions and delivery requirements.
Typical functions
- Fluid-loss reduction
- Rheology modification
- Filtration cake improvement
Product information
- Chemical name
- Carboxymethyl Cellulose
- Formula / class
- CMC
- Appearance
- White to off-white powder or granules, depending on grade and producer.
- Packaging
- Industrial bags, typically 25 kg. Confirm packing with the selected manufacturer.
CMC and PAC are related but not identical. Substitution should be based on mud formulation, salinity and required API fluid loss, not on name similarity.
