Use Of Barite In Drilling Mud

Mud weights up to 20 lbmgalUS 2.40 sg can be achieved in most drilling fluids while still maintaining good rheological properties. MI BAR barite is also excellent in formulating special kill fluids and barite plugs that often reach 22 lbmgalUS 2.64 sg for well control procedures.
