Drilling fluids maintenance, clean up & disposal cost as well as the overall cost of boring, can be reduced dramatically when proper solids control techniques are utilized. These facts were recognized in the oil industry in the late 1800’s. When open earthen pits we used to separate the cuttings from the borehole. This was accomplished by a series of weirs and settling pits that allowed the solids to naturally settle out by using gravity. The clean mud then flowed into a suction pit to be re-pumped down hole. This was the first solids control technique ever used.

Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well 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 will work as a mud agitator. All these equipment are mounted on the top of the mud tank. After separating the solids, the clean mud will be pumped into the borehole again.

Solids control system is an indispensable part for every drilling rig. But many newcomers of drilling industry have no idea of the functions of solids control equipment. The mobile solids control system has the advantage of safety, efficiency and environmental protection, greatly increase the automation of the solids control system. It is proved that the drilling not only has a simple structure, a safe, reliable and compact design, but it also has unparalleled advantage of movement convenience and a wide range of application.

KOSUN Mobile Solids Control System is a complete self-contained, high-performance solids control unit. The advanced design utilizes proprietary technology to ensure the very highest processing efficiencies over a wide range of oil, synthetic, and water-based muds. The entire operation is process-controlled and continuously adjusted based on the mud rheology. These adjustments ensure optimal solids removal and maximize fluid recovery while minimizing fluids loss and environmental impact. Providing the safe operation is of the utmost importance. KOSUN’s system is designed and managed to ensure the safety of personnel, equipment, and surrounding environment.
