Use of bentonite clay with drilling fluids is a serious issue for oil well drilling and creates major mess ups like uneven flocculation, rheological loss and exorbitant erosion. To mitigate such undesirable circumstances, Partially Hydrolyzed Polyacrylamide (PHPA) polymers are utilized as additives to bentonite water based liquids for shale stabilization and also in High Temperature - High Pressure applications due to its better heat stability. Moreover, it also forms a protective layer on cuttings so as to forestall agglomeration and limiting fluid loss.

Key Features and Benefits

  • Stabilize reactive shale and clay formations
  • Improve borehole stability
  • Enhance slurry rheological properties
  • Alleviate mud rings, bit balling and booting-off in clay formations
  • Reduce drill pipe torque and pumping pressure
  • Minimize rod chatter in diamond core drilling
  • Create ""stiff-foam"" and maintain foam integrity
  • Flocculate non-reactive solids in reserve pit at low concentrations
  • Mixes easily with minimum shear in fresh water
  • Helps provide effective clay and shale stabilization with lower viscosity
  • Helps impart high degree of lubricity
  • Non-fermenting
  • Breaks down chemically with household bleach (sodium hypochlorite)

Handling Measures
and Precautions

Proper human safety products such as splash goggles, lab coat, vapor respirator, NIOSH approved gloves and boots should be worn while handling and applying chemicals. Splashes on the skin should be washed off with water immediately. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. Should not be injected.


Should be stored in original vented containers, away from heat, direct sunlight and combustibles. Store in cool, dry well ventilated area in tightly closed, plainly labeled containers. Keep away from incompatible materials.
