BorDrill™ FLW

Fluid Loss Additive for Drilling Mud



Hexion’s BorDrill™ FLW fluid loss additive is designed specifically for high pressure/high temperature (HP/HT) fluid loss control, clay particle inhibition, and borehole stabilization. It is formulated for superior performance in highly contaminated mud systems at elevated temperatures up to 204°C [400°F].

It is a water-soluble, extremely high molecular weight, powder resin.



  • Effective in a wide range of fresh water, seawater, saltwater, and contaminated systems
  • Temperature stability up to 204°C [400°F]
  • Does not increase the rheology of drilling fluid system
  • Cost effective in a wide range of applications


Our BorDrill FLW fluid loss additive performs exceptionally well and tolerates various water-soluble salts used in oilfield applications. The monovalent salts like sodium and potassium have been found to be compatible at concentrations of 100,000 mg/L (NaCI). Divalent salts such as calcium and magnesium are tolerated (Ca++ 1,000 mg/L) as well. This tolerance and resistance provides the foundation for excellent API and HP/HT fluid loss control.
