Barite Plugs Applications, Formulation & Operation
A Barite plug is a barite slurry pumped down the drill pipe and placed at the bottom of the wellbore. A successful Barite plug should accomplish two things: Initially, the weight of the barite slurry should kill the well. After some time, the settled barite plug should mechanically block any flow up the wellbore.
