Viscosity and Filtration Control Aid for Water Based Drilling Fluids.

CMC- LV Carboxy methyl cellulose is an effective additive for reducing the A.P.I. filtration rate in most water based drilling fluids. CMC- LV provides no appreciable increase in mud viscosity and provides a cost effective means of improving water based drilling fluid performance.

Applicable Fluid Types:

CMC-LV is applicable in the following general types of fluid systems.

  • Freshwater Muds
  • Seawater Muds
  • Saltwater Muds (up to and including saturation)
  • KCL Muds
  • Solids Free Brine (NACL and KCL)
  • Native Muds

Functions:

CMC-LV may be used efficiently in the indicated types of fluid to:

  • Reduce the filtration rate of the fluid
  • Increase and improve the fluid rheology (including suspension and hole cleaning)
  • Stabilize fluid rheology in the presence of contaminants
  • Coat and encapsulate cutting and solids in the drilling fluid, thereby inhibiting the swelling and disintegration of water sensitive solids.
  • Improve the character and consistency of wallcake, thereby reducing the potential for stuck pipe.
