Baroid EZ-MUD® DP

EZ-MUD® DP borehole stabilizing dry synthetic polymer contains high molecular weight partially hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer.

EZ-MUD DP water-soluble polymer, when mixed with fresh water, hydrates quickly and forms a clear, viscous fluid. EZ-MUD DP dry polymer provides excellent borehole stability through a coating mechanism (encapsulation).

    The use of EZ-MUD DP dry polymer assists and promotes the following:
  • Stabilize reactive clay and shale formations
  • Keep trench excavation open during the construction
  • Produce high viscosity solids-free slurry
  • Enhance rheological properties of a low-solids drilling mud
  • Enhance core recovery in continous wireline coring operations
  • Flocculate non-reactive solids in reserve pit at low concentrations
  • Reduce torque and drag


  • Can disperse easily with minimal shear
  • Efficient shale/clay stabilizer and viscosifier
  • Helps impart high degree of lubricity
  • Compatible with other drilling fluid additives when added in proper sequence
  • Non-fermenting
  • No petroleum distillates involved
  • Breaks down chemically with bleach (sodium hypochlorite)
  • NSF/ANSI Standard 60 Certified
