This video shows how these solids control equipment (shale shaker, desander, desilter, mud cleaner, centrifuge and pumps) works.
Two Aplication Of Solids Remove For Drilling Optimization to Overcome High Torque
Fine solids result
From drilling fluid properties point of view, it is beneficial to minimize drilled solids content. This can be achieved by mechanical treatment, chemical treatment, dilution, and/or mixing new mud. All the above methods, will lead to additional cost impact. Thus, utilization of proper solids removal was required to balance between mechanical treatment and dilution method to reduce solids at acceptable cost.

Drilling Fluid Cleaner
Drilling fluid cleaners were equipment of solids control, also called mud cleaner or mud conditioner, etc.. Drilling fluid cleaner was evolved in the early 1970s to remove fine drilled solids from medium weighted mud without excessive loss of barite and fluid. It is also proved valuable tools in drilling loop closed systems and other applications (dispersed weighted). Drilling fluid cleaner use a combination of desander and/or desilter hydrocyclones and very fine mesh vibrating screens (120~400 mesh) to remove fine drilled solids while returning valuable mud additives and liquids back to the active mud system.
Drilling Cuttings Separation
Mineralogy of Cuttings
Drill cuttings are particles of crushed rock produced by the grinding action of the drill bit as it penetrates into the earth. Drill cuttings range in size from clay-sized particles (~ 2 μm) to coarse gravel (> 30 mm) and have an angular configuration. Their chemistry and mineralogy reflect that of the sedimentary strata being penetrated by the drill.
