Barite Heavyweight Additive

Barite heavyweight additive is a barium sulfate material used to weight drilling muds and cement slurries.  Typically, 85 to 90% of barite additive will pass through a 325-mesh sieve.

Barite additive is effective at bottomhole temperatures (BHTs) between 80°F and 500°F (27°C and 260°C). A barite additive concentration of 135 lb/sk of cement will provide a maximum slurry weight of 19 lb/gal.

Barite additive can provide the following benefits:

  • By increasing slurry density, it helps restrain high formation pressures and improve mud displacement.
  • It is applicable in deep, high-temperature wells.
  • The Environmental Protection Agency (EPA) does not classify barite additive as a hazardous waste.
