EZ-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. 

Applications and Functions

  • 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 


  • NSF/ANSI/CAN Standard 60 certified 
  • 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)
