FLO-PLEX fluid-loss-control additive is a polysaccharide derivative used to control filtration in the DRILPLEX system at recommended concentrations.
FLO-PLEX additive will not destroy the low-end rheology of the DRILPLEX system as observed with conventional anionic fluid-loss-control agents. The additive is effective in seawater fluids, but all hardness should be treated out before the FLO-PLEX additive is added. It can be used in any other type of fluid where starches and cellulosic additives are permitted. The temperature stability of FLO-PLEX additive is about 250 degF [120 degC] but may be extended to 300 degF [149 degC] by the addition of a thermal stability agent. FLO-PLEX additive is resistant to bacterial degradation.
