High temperature Fluid Loss Additive and Rheology Modifier Aid for  Water Based Drilling Fluids

Partially Hydrolyzed Polyacrylamide (Liquid) is a liquid emulsion of acrylic co-polymers designed to improve performance of all types water based mud systems (WBM), which imparts shale and bore-hole stability, viscosity modification, lubricity, selective flocculation and assists with fluid loss control.

Partially Hydrolyzed Polyacrylamide (Liquid) provides a cost effective means of controlling drilling fluid characteristics and improving performance in a wide variety of fluid environments.

Applicable Fluid Types:

  • Freshwater mud
  • Seawater and saltwater mud ( up to and including saturation)
  • KCL and Muds with divalent ions
  • Solids free brine (NaCL, KCL and CaCL2) 


  • Provides effeceive control and modification of important drilling fluid properties with immediate effect and with low toxicity.
  • Enhances the removalp of drilled solids and improves penetration rates by reducing friction characteristics of the treated drilling fluid.
  • Excellent foam stabilizers for air drilling, while improving carrying capacity.
  • Improve the character and consistency of wall cake, thereby reducing the potential for stuck pipe.
  • Maintains performance at down-hole temperatures in access of 200 degree.

Recommended Treatment:

Concentration in the range of 0.5 – 5.0 lb/bbl are recommended. The quantity used would be dependent on the drilling fluid system, drilling depth and equipment.

It is recommended to be added directly via centrifugal mixers or pre-mixed. Bentonite should be added to system prior to adding Hydrolyzed Polyacrylamide.  Keep mud density below PH 11.


Packaged in 25  and 208 liter HDPE drums.
