Barite powder API is used in all drilling fluids for the purpose of increasing density. Increase mud density up to 21 lb/gal (2.5 g/cm3) in order to control formation pressure and stabilize the borehole. It is also soft, non-abrasive, contains few impurities and does not interact with other drilling fluid components.


Physical and chemical properties:

  • Appearance: Fine, beige coloured powder
  • Solubility: Insoluble in oil and water
  • pH in water: Neutral
  • Specific Gravity, g/cm3: 4.2 – 4.25
  • Bulk Density, kg/m3: 1,920 – 2,400


Environmental and safety handling recommendations:

  • Utilize  normal  precautions for  employee protection  when  handling  chemical  products. Use  of appropriate respirator gloves, goggles and apron is recommended for employee comfort and protection.
  • Barite powder API with content of Cd (≤ 0.06ppm), Hg (< 0.01ppm) is non-toxic and is considered to be harmless in the marine ecosystem.
