Carboxymethyl Cellulose (CMC)

The drilling fluid has good rheological and suspension stability and has strong resistance to various soluble salt pollution;

Product Details

Carboxymethyl cellulose, as a drilling fluid treatment agent can form thin, tough, and low permeability filter cakes on the wellbore, maintaining a low filtration rate of the drilling fluid.

Advantages

  • Control fluid loss
  • Inhibits hydratable, swelling shales
  • Increases resistance of clay muds to contamination
  • Good thermal stability to ≥ 130℃
  • Produces thin, slick, tough filter cake
  • Environmental compatible
  • Retards drilled solids build-up by inhibiting cutting disintegration
  • Works well at any salinity
