oil and gas offshore drilling rig

Pexotrol 552L

Environmentally preferred liquid copolymer fluid loss control additive for drilling fluids

Chemistry Type: Synthetic copolymer

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

Pexotrol 552L acts as a fluid loss control additive for diesel, ester, low toxicity mineral oil (LTMO), and iso-olefin based high temperature, high pressure (HTHP) drilling fluid formulations. Application temperature range from 149 - 204 °C (300 - 400 °F).

Product previously sold under the Pliolite DF01L name.

Key Advantages

  • Provides tight fluid loss control
  • Better dispersibility than powders in organic fluids, activating at low temperatures and with weak base oils
  • Contributes to low shear viscosity (even at high temperatures), reinforcing the suspension properties of the mud
  • Recoverable in recycled drilling fluids
  • Safe for marine life when used as intended
