Pexothin 733

Deflocculant and thinner for water-based drilling fluids

Chemistry Type: Synthetic copolymer

Function(s): Drilling Fluid Additives

Pexothin 733 deflocculant and thinner for water based drilling fluids provides a cost-efficient prevention of mud gelation under static, high temperature downhole conditions. Showing a high salt tolerance, it is effective in all water based drilling fluids.

Key Advantages

  • Superior deflocculation of bentonite at temperatures exceeding 150 °C (300 °F)
  • Cost-efficient prevention of mud gelation under static, high temperature downhole conditions
  • Improves filtration control (American Petroleum Institute (API), high temperature high pressure (HTHP))
  • Assures stable rheology in heavily weighted/high-solids muds
  • Effective in all water-based drilling fluids
  • High salt tolerance
  • Readily soluble in low-pH muds
  • Non-toxic and environmentally safe
