Chrome-Free Desco® Deflocculant

Chrome-Free Desco® Deflocculant is a proprietary tannin-based product used for rheology control in water-based muds. It is very effective for rheology control in areas with the strictest environmental regulations. It is effective in low concentrations without requiring the use of caustic soda.

Advantages

  • Environmentally compatible
  • Maximum deflocculation at low concentrations
  • Soluble in systems of high-salinity, high-hardness and at any pH
  • 4 to 8 times more effective than Chrome Free lignosulfonates, depending on conditions
  • Temperature tolerance in excess of 300ºF (149ºC)
  • Solution pH is 8.5± - no caustic needed to activate 
Application Material Needed
Low solids, semi-dispersed muds .1 to .5 ppb
(.3 to 2 kg/m3)
Supplement lignosulfonate, lignite muds Ratio of 4 Chrome Free lignosulfonate to 1 Chrome Free Desco® Deflocculant
Deep, hot drilling where lignosulfonate starts to degrade Ratio of 2-4 Chrome Free lignosulfonate to 1 Chrome Free Desco® Deflocculant
Conditioning drilling muds for packer fluids (any density) .5 to 3 ppb
(2 to 9 kg/m3)
for shear strength control
Inhibited KCl, lime or GYP muds .5 to 3 ppb
(2 to 9 kg/m3)
Cement preflush 2 to 3 ppb
(6 to 9 kg/m3)
 Cost

Total well costs are often lower as a result of higher product efficiency, fewer mud problems and less rig time. Chrome Free Desco® Deflocculant’s high potency results in lower costs for trucking, inventory, and handling.
