Filtration-control additive for DRILPLEX drilling fluid system


FLO‐PLEX is a polysaccharide derivative used to control filtration in the DRILPLEX MMO drilling fluid system. Unlike conventional anionic fluid‐loss‐control agents, FLO‐PLEX additive will not destroy the low‐end rheology of DRILPLEX.

FLO‐PLEX is effective in seawater fluids, but all hardness should be treated out before the product is added. However, FLO‐PLEX additive may be used in any other type of drilling fluid where starches and cellulosic additives are permitted. The temperature stability of FLO‐PLEX is about 250°F (120°C), but may be extended to 300°F (149°C) with the addition of a thermal stability agent. FLO‐PLEX additive is resistant to bacterial degradation.


  • Specially designed as fluid‐loss‐control agent for the DRILPLEX system, but is effective in other water‐base systems
  • Resistant to bacterial attack
  • Temperature limits may be increased to 300°F (149°C) with the use of thermal extension additives
