The 4%vol drilled-solids concentration before drilling means that the drilling fluid contained 0.041000 bbl, or 40 bbl of drilled solids when drilling started. After drilling, these 40 bbl plus the 100 bbl of new drilled solids would be in the 1100-bbl drillingfluid system, or (140 bbl / 1100 bbl)100, or 12.7%vol drilled solids.

Fine solids, generally less than five microns, cannot be removed by the solids control equipment. Dictated by economic analysis, either partial drilling fluid system dilution or total system replacement needs to take place. The efficient use of solids control equipment minimizes the build-up of the undesirable drilled formation solids.
