Baroid EZ-MUD®

EZ-MUD® liquid polymer emulsion contains partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer and is used primarily as a borehole stabilizer to prevent reactive shale and clay from swelling and sloughing. EZ-MUD polymer emulsion is also added to low-solids drilling fluids to increase lubricity, fluid viscosity, and to improve carrying capacity of air/foam injection fluids.

Applications/Functions

    The use of EZ-MUD liquid polymer assists or promotes the following:
  • Stabilize reactive shale and clay formations
  • Improve borehole 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

Advantages

  • Mixes easily with minimum shear in fresh water
  • Helps provide effective clay and shale stabilization with lower viscosity
  • Helps impart high degree of lubricity
  • Non-fermenting
  • Breaks down chemically with household bleach (sodium hypochlorite)
  • NSF/ANSI Standard 60 Certified
