Barite (20.4μ) has two major functions in cementing operations:

Weighting Agent - Used where high pore pressures, unstable wellbores and deformable plastic formations are controlled by high hydrostatic pressures. Slurries with densities of up to 2280 kg/m³ (19.0 lbs/gal) can be prepared with Barite to control such wells.

Plugs - A Barite plug will seal the wellbore due to the high hydrostatic head pressure of the slurry. In addition the Barite slurry has a high filtrate loss causing it to dehydrate rapidly forming a plug. The viscosity and yield point of the Barite slurry must be kept low if the Barite is to settle and form a plug.

Barite can be mixed through the mud hopper as rapidly as needed. When large quantities are added to a mud system it may be necessary to add water to prevent mud dehydration. Additional water is required when blending Barite slurries (Barite Water Requirement = 0.04 L H₂O/kg Barite).
