Solids control is an important part in drilling that it uses combined equipment for drilling rigs to separate the solids in the drilling fluids which are crushed by the drill bits and carried out of the well to the surface.

Normally, solids control system is consisted of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner. When air enters the drilling fluids, vacuum degasser is used to separate the air. If no air is found in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank.
 

After separating the solids, the clean mud would be pumped into the borehole again. Each of these items plays a major role on the drilling rig as a filtration system to extract solids from the mud and return cleaner mud to the active system. It controls mud weight and allows the rig to drill faster and keep the properties of the well-bore hole consistent so that producing formations are protected, it helps prevent blowouts and is environmentally friendly. There is a demand for the services of solids control due to the rise in the price of oil and gas prices, domestic and developing countries supply and need for petroleum products, the explosion of shell well development due to new technologies like solids control sweeping across the country.
