BARACHEK, a high molecular weight substituted cellulosic polymer, provides filtration control and supplementary viscosity in water-based drilling fluids that contain moderate to high levels of divalent cations.
*Applications/Functions: Control filtration ratesk, Retard shale swelling and disintegration, Provide supplementary viscosity in fresh water, sea water and brine-based fluids containing moderate to high levels of divalent cations.
*Advantages: Effective in fresh water, salt water and brine-based fluids, Effective in small concentrations for viscosity and filtration control, Stable at temperatures up to 300'F(1 49'C), Effective in moderate to high pH systems, Effective in moderate to high levels of divalent cations, Non-toxic, Does not require a bactericide. |
