Solids Control

Definition - What does Solids Control mean?

Solids control is a technique used in the drilling rigs to separate the solids crushed by the drill bits that are brought to the well surface. When unwanted solids are efficiently removed from the circulation system, the fluids in the wells are of highest quality. Efficient Solids Control results into less replacement of fluids, less waste and few additives that are needed to be removed and disposed. This also significantly decreases the risk of downhole related problems due to excessive solid contents in the drilling fluid.

Petropedia explains Solids Control

When proper Solids Control techniques are used, they can reduce the drilling fluid clean up, maintenance cost, and the disposal cost. The Solids Control system is divided into five stages:

  • Shale shaker.
  • Mud tank.
  • Desander.
  • Vacuum degasser.
  • Centrifuge.
  • Desilter.

The desander separates sand and silt from drilling fluids, the shale shaker separates big solids and the desilter is used to segregate solids. The desilter and desander can be combined to form one high efficiency mud cleaner. Vacuum degasser is used to separate air when air enters the drilling fluids. When the fluids are air free, the degasser can be used as a big agitator. All these stages are carried out on the top of the mud tank. After solids are separated, the clean mud is again pumped into the wellbore.
