- Drillpac® Polymer
Drillpac® Polymer
Drillpac® Polymer is a polyanionic cellulose that is available in both an ultra high-viscosity (HV) grade as well as a medium-viscosity (LV) grade in all of our locations throughout the world. Advantages of Drillpac® Polymer include:
  • Works well at any salinity
  • Controls fluid loss
  • Reduces clay invasion
  • Retards build-up of drilled solids
  • Increases penetration rates
  • Improves mud stability
  • Promotes thin, slick, tough filter cake
  • Reduces friction and frequency of differential sticking
  • Increases resistance of clay muds to contamination
  • Requires no preservative
  • Is non-polluting and safe to use in all locations
  • Emulsifies oil in water-based muds
  • Increases carrying capacity
Application Material Needed
Fluid-loss control .1 to 2 ppb
Inhibition / encapsulation .75 to 2 ppb
Improved filter cake .5 ppb
Improved and stabilized rheology .5 to 1 ppb
Reduced stuck pipe frequency .5 to .75 ppb
Emulsifier .1 to .5 ppb
Special Uses  
Semi-nondispersed muds .5 to 2 ppb
Workover / completion fluids .75 to 2 ppb
 Cost

Mud cost for interval drilled can range from less to more, depending upon system comparisons. Total well cost for interval drilled is usually less.

Mud Types

Water-based drilling muds, work over fluids and completion fluids of any salinity. Hardness below 500 ppm.

Mixing Requirements

Mix slowly through conventional jet-type hopper

Desired Solids Control Equipment

Unweighted systems: rig shale shaker, desander and desilter.
Weighted systems: fine screen shaker, centrifuge, and cleaner

Handling

For specific instructions on handling, refer to the MSDS.

Packaging 

50-pound multi-wall paper bags
