Pexoseal 731

Bio-based copolymer latex for aqueous drilling fluids

Chemistry Type: Styrene butadiene copolymer (SB)

Function(s): Drilling Fluid Additives, Fluid Loss Control Additives

Pexoseal 731 latex provides fluid loss control and wellbore stability for high performance water-based drilling fluids in fresh or salt water with application temperature range up to 177 °C (350 °F). Designed for use in high temperature, high pressure (HTHP) environments.

Previously sold as GenCeal DF 8900.

Key Advantages

  • Organic colloidal soft nanoparticles, deformable and compressible, reduce non-productive time
  • High tolerance to salts and multivalent ions and acids
  • Plug nanosized pores to reduce permeability of filtercake in tight formations
  • Sealing additive for wellbore stability
  • Over time, the emulsion can form a film in the filtercake at high temperatures, strengthening the wellbore
  • For high performance water-based drilling fluids in fresh or salt water at bottomhole temperatures up to 177 °C (350 °F)
