Just as the nature of drilling-fluid solids affects the efficiency of solids control equipment(GN Solids Control ), the nature of the solids also plays an integral role in the properties of drilling fluids, which in turn affect the properties of the solids and the performance of the equipment.This intricate and very complex dynamic relationship among the solids, drilling fluid, and solids-control equipment is represented in the Figure below.

Any change made to one of these affects the other two, and those in turn affect all three, and so on. To optimize a drilling operation, it is important to understand how the solids affect bulk mud properties, particularly rheology, hole cleaning, filtration, drilling rate (rate of penetration [ROP]), along with surface properties such as shale inhibition potential, lubricity, and wetting characteristics.
