Corrugated screen have up to 125 percent more surfafce area than conventional flat screens. Gravity forces the solids into the corrugated screen’s troughs, thus allowing more fluid to pass through the top of the screen. With conventional flat screens, conductance is reduced as solids form a continuous bed that impedes fluid flow.
GN finished one drilling cuttings tratment system to Australia and will be ready for delivery soon. It contains:
1) Hi G Dryer
2) Centrifuge
3) Auger
4) Mud Tank
The VCCS offers a safe and efficient means for containing drill cuttings after drilling mud recycling at a rigsite. The movement of air through the system allows the collection of drill cuttings and other drilling wastes, such as centrifuge waste and pit cleaning operations.
The system can collect wastes fromthe shakers and centrifuges or it can be configured to collect waste from pit cleaning operations.
CBM drilling mud normaly water base mud, a decanter centrifuge will help to separate fine solids 2-5 microns. Main purpose to separe fine solids:
1) Keep good mud weight
2) Keet mud densitity
3) Avoid mud get weighter and weigher which desilter can’t separate

Cuttings blowing pump ( CBP ) blows drill cuttings and centrifuge waste from a collection point on the rig to a temporary bulk storage tank on the rig. Benefits of CBP
1) High capacity in excess of 35MT per hour
2) Allows cuttings to be blown straight to a boat
3) Reduces exposure to drilling wastes on the rig
4) Carane lifts are minimised, reducing the risks associated with lifting numerous drilling waste containers from the rig to a boat
