EZ-Mud Plus


EZMUD_PLUSEZ-MUD PLUS liquid polymer emulsion contains partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer and is used primarily as a viscosifier and borehole stabilizer to prevent reactive shales and clays from swelling and sloughing. EZ-MUD PLUS is also added to low-solids drilling fluids to increase lubricity and to improve the carrying capacity of air/foam injection fluids.EZ-MUD PLUS polymer emulsion is a high molecular weight version of EZ-MUD polymer emulsion with improved properties.

  • Liquid form – mixes easily with minimum shear in fresh water
  • Efficient shale/clay stabilizer and viscosifier
  • Non-fermenting
  • Cost-effective – small amounts produce desired results
  • Breaks down chemically with bleach (sodium hypochlorite)
  • NSF/ANSI Standard 60 Certified



The use of EZ-MUD PLUS polymer assists or promotes the following:

  • Stabilize reactive shale and clay formations
  • Improve borehole and excavation stability
  • Enhance slurry rheological properties
  • Alleviate mud rings, bit balling and booting-off in clay formations
  • Reduce drill pipe torque and pumping pressure
  • Minimize rod chatter in diamond core drilling
  • Create “stiff-foam” and maintain foam integrity
  • Flocculate non-reactive solids in reserve pit at low concentrations

  • It is recommended that Soda Ash (sodium carbonate) be added to the make-up water prior to the addition of EZ-MUD PLUS high molecular weight liquid polymer emulsion for reduction of excess calcium and pH adjustment.
  • The above are generalized concentrations of EZ-MUD PLUS high molecular weight liquid polymer emulsion to be added to water-based drilling fluids. The ultimate usage concentration will be based on local geology, application and mixing efficiency.
