  • Why does PHPA have a high viscosifying power?
  • PHPA has high viscosifying power due to its high molecular weight and the electrostatic repulsion of the carboxylate groups present in its structure, which provide a higher hydrodynamic volume in solution, increasing the viscosity of the polymeric solution ( Kamal et al., 2015a; Leblanc et al., 2015; Li et al., 2017 ).
  • Why is PHPA used in drilling fluids?
  • For instance, PHPA is commonly used in drilling fluids as a viscosifier, fluid loss control agent, and shale inhibitor. It is highly effective in improving the rheological properties of drilling fluids, such as increasing their viscosity and improving their fluid loss characteristics ( Wang J. et al., 2025 ).
  • What is CMC & PHPA polymer?
  • Both CMC and PHPA polymer act as fluid loss-reducing agents and viscosifiers for normal bentonite water-based mud. The mud is further enhanced to counter certain swelling formations such as shale through the addition of NaCl and KCl.
  • Can hydrophobically modified associative polymers be used as viscosifying agents?
  • In general, hydrophobically modified associative polymers and thermo-viscosifying polymers are promising alternatives for application as viscosifying agents for enhanced oil recovery, especially in harsh reservoir conditions (high salinity and temperature).
