What Is Solids Control with picture wiseGEEK

May 14 2020 · Solids control refers to a well drilling technique used to provide drilling fluid to deep well drilling rigs and to clean this fluid for further use The technique is often called mud drilling because it uses a flow of water and mud to bring solids out of bore holes and cool the drilling rig equipment This drilling fluid also facilitates the necessary hydrostatic pressure to prevent the
