According to our (Global Info Research) latest study, the global Drilling Solids Control System market size was valued at USD million in 2022 and is forecast to a readjusted size of USD million by 2029 with a CAGR of % during review period. The influence of COVID-19 and the Russia-Ukraine War were considered while estimating market sizes.
Solids control is a technique used in a 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, a solid control system contains five stages: the mud tank, oilfield shale shaker, vacuum degasser, desander, desilter, and centrifuge. The drilling solids control system will separate unuseful drilling cuttings and other solids among drilling fluids. It will correct drilling mud property and keep the drilling fluids performance good. Solid control effect to well drilling also includes holding proper gravity, density, weight, etc. Good solids control to well drilling will produce good quality drilling fluids during whole well drilling. The good drilling fluids will influence good drilling greatly. Use good drilling fluids, the well drilling will be fast and efficient, the drilling cost will be less than those bad solids control well drilling.
