Pexotrol 952

Environmentally preferred copolymer fluid loss control additive for XHTHP drilling fluids

Chemistry Type: Synthetic copolymer

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

Pexotrol 952 acts as a fluid loss control additive for diesel, ester, low toxicity mineral oil (LTMO), iso-olefin and paraffin-based extremely high temperature, high pressure (xHTHP) drilling fluid formulations. Application temperature range greater than 260 °C (500 °F).

Previously sold under the Pliolite DF08 name.

Key Advantages

  • Capable of giving tight fluid loss control at low dosages
  • Produces deformable soft colloidal micro-gel particles in organic fluids
  • Has been shown, both in laboratory testing and in the field, to not damage the formation
  • Contributes to low shear viscosity (even at high temperatures), reinforcing the suspension properties of the fluid
  • Recoverable in recycled drilling fluids
  • Safe for marine life when used as intended
