PHPA Powder

A partially hydrolyzed polyacrylamide polymer used as a cuttings encapsulator, shale stabilizer and friction-reducing additive in water-based drilling fluids. The polymer coats drilled solids and reactive shale surfaces, helping control dispersion while improving hole cleaning and wellbore condition.

Used in: Freshwater muds; calcium/sodium brines; KCl mud systems.

Why it is used: To encapsulate cuttings, reduce shale dispersion, improve wellbore stability and provide friction-reduction benefits.

Key functions / benefits

• Cuttings encapsulation
• Shale and wellbore stabilization
• Viscosity and friction-management support

Typical form: Free-flowing powder

Suggested packing*: 25 kg moisture-resistant bags; palletized supply on request
