Two weeks ago, GN Solids Control completed one set 40 feet water based drilling waste treatment system that is used for oilfield waste management service. Water based drilling waste is coming from the drilling projects where
use the water based drilling fluids to cool down the drill bit, protect the drilling well wall and take out the drilling cuttings.

The main equipment included in this 40 feet water based drilling waste treatment system are as follows:

1) High G force dryer shakers used to further drying the cuttings discharged from the primary solids control equipment, wide open deck design allows the feeding of waste easily
2) Dosing System for mixing chemicals that will fed to the centrifuge for flocculation process
3) High speed Decanter Centrifuge for liquid and solids separation
4) Mud Tank unit under the shaker to collect the liquid going through the shaker screens
5) Screw Pump transfer the fluids to decanter centrifuge for polishing

Drilling Waste Management System

Working diagram of the 40 feet water based drilling waste management system

The drilling waste, always coarse drilling cuttings, was fed to dryer shaker for further drying, and then the screw pump will transfer the drilling fluids with ultra fine solids to the decanter centrifuge (It is also dewatering centrifuge). In the meanwhile, the chemical dosing system mixes polymer, once the polymer solution is cured. The diaphragm pump transfers the polymer to the dewatering centrifuge. The ultra fine solids will get together once meet with the polymer, which will help the centrifuge to separate the solids. The drilling waste management system for separating the ultra solids in waster based drilling fluids is also called dewatering system.

Equipment features of the 40 feet water based drilling waste management system

GN’s high G force dryer shaker has up to 8 G force. with 4 panels composite material screen, the Dryer shaker has an excellent separation and drying performance.
GN high speed decanter centrifuge and feeding screw pump are VFD driven and controlled by PLC. The operators could set the suitable parameters to treat different kinds of drilling fluids.
Besides the drilling waste management system for water based mud, GN also developed the equipment for oil based mud. Even the oily sludge treatment solution is one of GN’s main businesses. GN’s system for drilling waste management has many performance cases that will prove GN equipment quality and availability. This is why customers choose GN Solids Control.
