BARITES 4.2 SG (ASHA BAR 2000)
BARITES 4.2 SG (ASHA BAR 2000) BARITE is ground barium sulphate that meets API Specification 13A, Section 20. BARITE is used to increase the density of drilling fluids when required to control formation pressures. BARITE has a minimum specific gravity of 4.2 and can be used to increase density in water and oil-based systems up to 2516 kg/m³.
M-I BAR barite
M-I BAR barite is also excellent in formulating special kill fluids and barite plugs that often reach 22 lbm/galUS [2.64 sg] for well control procedures. An increase in volume of approximately 1.4 bbl/tonUS (0.25 m 3 /tonUK) can be expected from M-I BAR barite additions. Density increases can require water or base liquid dilution sufficient to ...
