One set water based mud (WBM) drilling waste centrifuge system is ready for delivery at GN Solids Control factory. The buyer is Beijing famous oil Service Company with rich experience in solids control service & waste management service. The end user is subsidiary company from China National Petroleum Corporation (CNPC).

The WBM drilling waste centrifuge system is used for not falling to the ground project, to dry the cuttings from shale shaker discharge. Generally working flow: shaker discharge → Hi-G dryer shaker with high API number shaker screen → NEMO pump → High Speed decanter centrifuge → active tank (usable drilling fluids).

The Hi G dryer & centrifuge system including below parts:

1 X Hi G dryer shaker: GNZS594HGE-LD Hi G dryer shaker with 4 pcs shaker screen is popular because of the large capacity 600gpm and Hi G force for better performance. After treated by Hi G dryer, the Oil on cuttings / water on cuttings can reach to about 10%.
1 X Decanter Centrifuge: GNLW363CG-VFD high speed decanter centrifuge can be working for solids control, drilling waste management, dewatering centrifuge etc, as the big variable speed range from 0 to 3200rpm. The positive pressurized control panel is installed on the side skid for compact design and convenient use.
2 X screw pump: GNG30A-075 screw pump is for transferring drilling mud and another pump feeding drilling fluids to centrifuge.
This drilling waste centrifuge system with Hi G dryer shaker can also be used for oil based mud drilling waste management. Even, the OOC after Hi G dryer is about 10%, which is much higher than result (OOC is about 3%-5%) from Vertical cuttings dryer, some customer still like Hi G dryer in some job cases. There are two advantages of Hi G dryer: lower renting cost / purchase cost and lower energy consumption. The Hi G dryer shaker with 2 vibration motor only consumes less than 4kw; however, the vertical cuttings dryer will consume at least 55kw. On the rig, the power distribution on drilling waste management sometime is strictly limited. In this case, the user may consider about Hi G dryer instead of vertical cuttings dryer.

After treated by on line drilling waste management system, the usable drilling fluids is recovered and the solids waste,
If oil based mud, may go to Thermal desorption unit (TDU) for final stage treatment.
If water based mud, may go to solidification / stabilization for final treatment.
GN Solids Control can offer the whole process equipment from solids control mud system, drilling waste management system, Thermal desorption unit (TDU) and solidification / stabilization equipment.
