 |
BARANEX, modified lignin powder, provides filtration control in water-based drilling fluids.
It is compatible with lignosulfonates and lignites and is capable of handling common mud contaminants, particularly calcium and chloride.
BARANEX does not require additions of caustic soda/potash to solubilize and functions at a wide range of pH conditions.
*Applications/Functions: Provide filtration control at temperatures approaching 400'F(205'C) in waterbased drilling fluids, Replace basic filtration polymers that lose their ability to control HTHP filtration rates at elevated bottomhole temperatures.
*Advantages: Reduces fluid loss at temperatures approaching 400'F(205'C), Does not increase viscosity, Functions in most water-based drilling fluids, Solubilizes readily in water, Maintains filtration control in the presence of contaminants of calcium, magnesium, and solids. |
