Solids control is a closed loop system which used to separate the solids in the drilling fluids that are crushed by the drill bits during drilling and carried out of the well surface. A solid control system contains sevaral stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge.
The shale shaker is used to separate big solids with diameter above 75μm, the desander addresses solids from 45-74μm, and the desilter segregates solids between 15-44μm..A vacuum degasser is used to separate the air from the drilling fluids. After separating the solids, the clean mud can be pumped into the borehole again.
