Vertical cuttings dryer is an ideal equipment to treat the oil based drilling cuttings and SOBM, when used for water based drilling cuttings, high G drying shaker can work better and with higher cost performance ratio. The cuttings discharged from vertical cuttings dryer with oil content in the cuttings is below 5%, in some countries, it is permitted to be disposal directly or for landfill. In some other countries, it needs further treatment such as burning, TDU, Biodegradation or injection. The treated fluids will flow to an intermediate tank, then decanter centrifuge feeding pump will transfer the fluids to VFD decanter centrifuge to separate more fine solids from the fluids, the treated fluids will be collected by an centrifuge tank and transfer to active mud tank system for reuse or chemical mixing tank to prepare for new drilling fluids. The drilling waste management system is environmental friendly system to reduce the drilling waste and reduce the harmful to the earth, also can recycle more useful drilling fluids for the customer and save the drilling cost, especially in some countries the zero discharge system is compulsory, otherwise they cannot get permit for drilling project.

Drilling Waste Management Equipments for Pitless Solution

Drilling waste management equipments for pitless solution including vertical cuttings dryer, high G drying shaker, VFD decanter centrifuge, screw conveyor, sludge vacuum pump, screw pump, etc. Recently GN solids control shipped one batch of drilling waste management equipments to International oilfield service company. The client collect the drilling waste from onshore and offshore rig site and dump the drilling waste together, with both water based mud and oil based mud drilling waste. The operator need one drilling waste management system which can treat both water based mud and oil based mud.

The working principal is as below:
The sludge vacuum pump pick up the drilling waste to the collection hopper of screw conveyor, which will transfer the drilling waste to high G drying shaker and vertical cuttings dryer. If there is no vacuum pump, an auger system to collect all the drilling waste from the rig solids control system is necessary. The cuttings are separated out by high G drying shaker and vertical cuttings dryer and collected by skips, the fluids are dropped into the mud tank, the centrifuge feeding pump transfer the clean fluids to decanter centrifuge to separate the fine solids, the cut point is 2~5 microns. The clean fluids cn be reused for drilling rig and prepare for new fluids. By using proper chemicals, the separation cut point is up to 1 microns, most of the solids can be separated out.


The pitless solution or zero discharge system is consist of solids control system and drilling waste management system, the solids control system is working to reduce the discharged drilling waste, which will be collected by screw conveyor system and transferred to drilling cuttings treatment system. The discharged solids can be collected by waste container for land fill or injection. The whole process is environmental friendly design without needing a waste pit on the ground.
