Tapioca starch

Description

Specifically designed modified starch-based fluid loss reducer. It is used to minimize fluid loss in mineralized muds and initial penetration drilling muds. The reagent has a special feature of synergistic interaction with biopolymers (xanthan gum) and an ability to reach uniquely high viscosity values at low shear rates.

Range of applications

The reagent is used for fluid loss control. Unlike other fluid loss reducers, it provides maximum LSRV (low shear rate viscosity) values in combination with biopolymers. It is used in initial penetration drilling muds for the creation of thin, dense, elastic and tight filter cake which is easily removed at a minimum drawdown value. It is used for conditioning of water-based fresh and mineralized drilling muds, production of kill units and conditioning of well-completion fluids.
