Desco® Deflocculant
Desco® Deflocculant is a proprietary tannin-based product used for rheology control in water-based muds. It is readily soluble over a wide range of temperatures and is effective in low concentrations without requiring the use of caustic soda.

Advantages

  • Maximum deflocculation and shear strength reduction at low concentrations

  • 4 to 8 times more effective than lignosulfonates, depending on conditions

  • Soluble in systems of high salinity, high hardness and at any pH

  • Scavenges oxygen and inhibits corrosion

  • High-temperature rheology control; proven effective in excess of 400ºF (204ºC)

  • Solution pH is 8.5± - no caustic needed to activate

  • Reduces the effects of cement contamination

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.

Mud Types

Most water-based mud formulations

Mixing Requirements

Mix through hopper

Handling

For specific instructions on handling, refer to the MSDS.
