S e c t i on 1 5 - P a ge2 May 2013 EZ-MUD ® DP Bor ehole Stabilizing Dry Polymer Description EZ-MUD DP is a fr ee-owing, dry granular synthetic polymer containing partially hydr olyzed polyacrylamide/ polyacrylate (PHP A) copolymer . EZ-MUD DP , a water -soluble polymer , disperses and dissolves in fr esh water rapidly . When mixed with fr esh water , EZ-MUD DP hydrates quickly and forms a clear , viscous uid. With its high molecular weight and optimum char ge density , EZ-MUD DP pr ovides excellent bor ehole stability thr ough a coating mechanism (encapsulation). Applications/Functions • Stabilize r eactive clay and shale formations • Keep tr ench excavation open during the construction • Pr oduce high viscosity solids-fr ee slurry • Enhances rheological pr operties of a low-solids drilling mud • Enhance cor e r ecovery in continuous wir eline coring operations • Flocculate non-r eactive solids in r eserve pit at low concentrations • Reduces tor que and drag Advantages • Disperses easily with minimal shear • Ef fcient shale/clay stabilizer and viscosifer • Imparts high degr ee of lubricity • Compatible with other drilling fuid additives when added in pr oper sequence • Non-fermenting • No petr oleum distillates involved • Br eaks down chemically with bleach (sodium hypochlorite) • NSF/ANSI Standar d 60 Certifed www .dsiundergr ound.com
