Sodium Carboxymethyl Cellulose (CMC) for Oil Drilling

Sodium carboxymethyl cellulose (CMC) is a highly purified and refined cellulose ether that is derived from natural cellulosic materials. CMC is free-flowing powder available in white or yellowish color, it features high water solubility and light transmittance after being dissolved therefore resulting in better rheological property and stronger thixotropic behavior. CMC also has high degree of substitution (DS), excellent acid resistance and salt tolerance.


Advantages
  • Cost-effective fluid loss control polymer
  • Effective filtration control additive in most water-based drilling fluids
  • Effective in low concentrations
  • Non-toxic, and not exposed to bacterial fermentation and calcium contamination
  • Can be used in most water-based fluid systems

Landoil CMC-HV

Landoil CMC-HV is a high molecular weight, high viscosity dispersible carboxymethyl cellulose fluid loss additive, it is intended to increase viscosity and reduce API filtration rate in water-based drilling fluids.

Applications

CMC-HV is a high viscosity and cost-effective additive that can be added in all types of water-based drilling fluids, from fresh water to saturated salt water, to reduce the API filtration rate. It is also appropriate for fluid loss and rheological control in low-solid content mud, as well as increasing viscosity in any types of mud.

Landoil CMC-LV

Landoil CMC-LV is a low viscosity technical grade dispersible fluid-loss reducing additive used for reducing API filtration rate in water-based drilling fluids, while causing the least amount of viscosity increase possible.

Landoil CMC-LV Specifications
Appearance Yellowish free-flowing powder
Nature of Polymer Sodium Carboxymethyl Cellulose
Moisture Content Max.10%.
In accordance with API 13A CMC-LV specification
Viscometer Dial Reading at 600 r/min Max.90
Filtrate Volume Max.10cm3
Applications

Landoil CMC-LV is a cost-effective additive used in fresh water and brackish water systems for fluid loss control. It is an ideal fluid loss reducer for both dispersed and non-dispersed drilling fluids.
