Many customer wondering the difference of the 2 kinds of dryr and do not know how to choose the suitable one.
High G shale shaker (H-G) VS Vertical G cuttings dryer (V-G)
GNZS594 High G shaker dryer
1) Price of Vertical G cuttings dryer (V-G) is much more higher than High G shale shaker (H-G)
2) Their application field is different. High G shale shaker (H-G) is mainly used to treat water based mud drilling cuttings. While Vertical G cuttings dryer (V-G) mainly used to treat oil based mud drilling cuttings
3) High G shale shaker (H-G) can be used to separate oil based mud drilling cuttings, while Vertical G cuttings dryer (V-G) cannot used to treat water based mud drilling cuttings
Vertical G Cuttings Dryer
Difference of High G shale shaker (H-G) & Vertical G cuttings dryer (V-G) for oil based mud (OBM)
Both High G shale shaker (H-G) & Vertical G cuttings dryer (V-G) can be used for oil based mud, but there is difference on performance.
High G shale shaker (H-G) can reduce the oil on cuttings (OOC) to 15~20% after treatment. For many customer, it is not dry enough. Other treatment process is necessary. But the Vertical G cuttings dryer (V-G) can reduce the oil on cuttings (OOC) to 3~5%. The discharge from Vertical G cuttings dryer (V-G) can take away directly for road construction or other function. Or Feed to Thermal Desorption Unit for further treatment.

There are rubber ring for sealing on most shaker screen model, like Derrick503 screen, Derrick48-30 shaker screen, Brandt Cobra shaker screen, GN Solids shaker screen, and many other shaker screen models.
Functions of the sealing rubber:
1) Sealing between screens and shaker deck. To avoid un-treated dirty mud seep into mud system, and damage the mud system machine.
shaker screen sealing rubber
2) To reduce the bad effect of vibrating to the shaker screen. Protect screen from strong vibrating.
What will happen if the sealing rubber not workable
1) The screen frame will touch directly with shaker deck, and damaged within a very short time
2) The worst result is, if the screen rubber damaged, the dirty mud from well head will flow into mud system directly with much solids. It requires a higher capacity on downstream equipment processing, or even make damage to the downstream machine, like desander, desilter or vacuum degasser
If the material of the sealing rubber not strong enough and not very good at anti-corrosive, the high temperature drilling mud with heavy sand will damage the rubber very soon. The shaker screen will be broken very soon. Dirty mud flow into the mud system from the shale shaker deck with heavy sand and solids. It will have bad effect to the mud system.
GN Solids Control utilzie high quality material for sealing rubber. They can offer high quality shaker screen with reasonable price.
GN Solids Control has already developed the 20 foot containerized dewatering unit for drilling mud recovery, as without the chemically enhanced technology, operators would be left with the accumulation of colloidal and ultra-fine drilled solids in the drilling mud circulating system. Ultimately leading to excessive mud densities, pipe torque/drag, mud loss, disposal fees, and overall well cost.
GN 20 foot Containerized Dewatering Unit
GN 20 foot containerized dewatering unit including all the components for adding chemicals, dewatering polymers,and mixing systems. The dewatering unit control system is organized by the PLC system to allow automatically operation. The customter mostly use the dewatering unit for water based mud.The result is a polymer-enhanced flocculation of colloidal and ultra-fine drilled solids that can be efficiently removed by a GN high Speed decanter centrifuge.
The customer can choose to have the decanter centrifuge on a separate skid or included in the dewatering unit container, in such case the container should be 40 foot size to have enough space for setting up the centrifuges and the feeding pumps.
Dewatering Unit
Some case studies for the drilling mud dewatering unit
The Dewatering unit application at the well allowed reduction of the liquid-waste volume by 32% for the first two sections and by 27% for the entire well. Around 350 m3 of water was returned to the system for fresh drilling fluid mixing thus reducing the cost of water delivery. All drilling fluid left after the last section was also processed through the Dewatering unit and the returned water was used for completion operations. Although application of the Dewatering unit added additional upfront cost to the well construction, the waste-volume reduction allowed a 20% waste disposal saving as compared to offset wells.
