The high specific gravity of the NewBar weighting agent provides the necessary hydrostatic pressure to balance formation pressures while minimizing the input of lowgravity solids into the fluid system.


NewBar weighting agent is used to:

  • Increase the density of drilling fluids up to approximately 22 lb/gal (2.6 kg/L)
  • Control underground kicks and lost circulation with barite plugs

Treatment Recommendation

NewBar weighting agent is mixed directly into the drilling fluid system through the hopper or through the bulk tank hoppers.
