No rig can drill without generating waste. The types of waste generated include drill cuttings, waste water, spent drilling fluids, completion fluids and filtration wastes. Mostly, drilling waste from well head recovered while through solids control system and waste management system. Recovered fluids returned to well head for drilling. Dryed cuttings moved away by trucks for construction or paving.

But while the well finished or rig stop, drilling fluids from well head cannot discharge directly to environment. Drilling cuttings can be treated by solids control and waste management system:shale shaker, desander, desilter, centrifuge,high G., vertical cutting dryer,etc…

Great amount or fluid-phase waste generated, which is formerly recycling to wellhead for drilling. In this case, liquid-mud plant need be used.

A common type of liquid-mud plant is actually a series of VFD decanting centrifuge and feeding pump. Before go into decanting centrifuge, the useful drilling fluid go through flocculation system for treatment. Fine solids can be polymerized into larger size for an easy separation.


GN Solids Control as the only one Chinese company specialized both for solids control and waste management, has rich experience for international cooperation.

GN will presenting ADIPEC with the decanter centrifuge or shale shaker.If you are interested for the solids control equipments for sale after ths ADIPEC.Please contact us.
