A whole Solids Control method shall incorporates shale shaker, vacuum degasser, desander, desilter, decanter centrifuge, mud agitator, mud gun, mud tanks. Etc. You could find that the largest consumed power is generated from desander and desilter. Because it required significant horse power centrifugal pump for feeding the desander cones & desilter cones to reach proper working performance with certain feeding pressure. It generally require 55kw/75kw centrifugal pump.
With more and more attention on environmental protection and energy saving, the solids control service company now are trying to by pass the desander & deilster. But how ?
Firstly, significant treating capacity shale shaker is needed with high mesh/API shaker screen. Thus, about 30 to 59 microns particles can be removed.
Secondly, huge treating capacity decanter centrifuge is needed. The is the last treating step of the mud to cut mud weight or recovery barite.
Consequently, only 2 phase solids control equipment is enough for the drilling. For this kind of new try, professional solids control engineer and mud engineer is required. If this design become successful and proof to be more efficient, a new generation will come for solids manage equipment manufacturer or solids manage service company.
