M-I WATE High-Quality Barite | Schlumberger

M-I WATE

High-quality barite

M-I WATE barite is a high-quality, drilling-grade barium sulfate used to increase the density of drilling fluids. This high-specific-gravity mineral is the most widely used weight barite, has application in all drilling fluid systems, and meets all API specifications for barite except density.

Typical Physical Properties  
Physical appearance Powder in various colors: gray, pink, or tan

Specifications  
Density Min. 4.1 g/cm3
Soluble hardness (as calcium) Max. 250 mg/kg
Particles >75 um (wet screen) Max. 3 wt%
Particles <6 um (sedimentation) Max. 30 wt%

Applications

M-I WATE barite can be used to increase the density of any mud system. Mud weights up to 19.6 lbm/galUS [2.35 sg] can be achieved in most drilling fluids while still maintaining good flow properties. M-I WATE barite is also excellent in formulating special kill fluids and barite plugs that often reach 21.5 lbm/galUS [2.58 sg] for well control procedures.

Advantages

  • Essentially chemically inert and insoluble, functions only in a physical manner
  • Does not react with other drilling fluid additives or interfere with their function
  • Minimally abrasive

Toxicity and handling

Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.

Packaging and storage

M-I WATE barite is packaged in 100-lbm [45.4-kg] multiwall paper sacks; 40-kg sacks; and big bags available in bulk. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
