Oilfield Solids Control

Drilling fluid solids control
1) Solids control mainly control drilling fluid used in oilfield. The details are drilling fluid is a fluid used to drill boreholes into the earth.. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes.
2) The three main categories of drilling fluids are water based muds (which can be dispersed and non dispersed), non aqueous muds, usually called oil based mud, and gaseous drilling fluid, in which a wide range of gases can be used.
3) The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore,
keeping the drill bit cool and clean during drilling, carrying out drill cuttings and suspending the drill cuttings while drilling is paused and the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage and to limit corrosion.
So the
solids control to drilling fluid is rather important in whole project of drilling rig
