Copolymer fluid loss control additive for oil based drilling fluids up to 149 °C (300 °F)

Chemistry Type: Synthetic copolymer

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

Pexotrol 332 provides fluid loss control for diesel, ester, LTMO and iso-olefin based drilling systems. It offers better performance at a concentration of up to 75% as compared to mined hydrocarbon resins such as asphaltite or black powders.

Previously sold under the name Verus DF101.

Key Advantages

  • Can deliver up to 50% less filtercake than other asphaltic resins
  • Easily activated; does not require several circulations to ensure product is properly dispersed
  • Produces soft and deformable particles with minimal formation damage
  • Effective at range of temperatures from top to bottom section
  • Lower impact on electric stability than black powders, potentially requiring fewer emulsifier additions
  • Does not interfere with logging measurements
