It may looks similar to some other products, but GN invent this unit, and now applying our own patent. GN is only able to provide the ViST vacuum shaker screen system to fit on GN won shale shaker, but also on clients’ existing shale shaker.

As the name implies, the ViST vacuum shaker screen system is including a ViST vacuum unit connecting with a collecting pan that is installed under the last panel shaker screen at the solids discharge port.

The plan is use a hopper with an opening at the bottom where connect to the vacuum unit via a hose. When the drilling cuttings pass through the last panel screen, the remaining large quantity fluids on the cutting would be sucked and get through the shaker screen mesh to the hopper then to the vacuum unit. A buffer tank will be needed.

Why Choose GN ViST?

1. The Vist vacuum shaker screen system is suitable for OBM, WBM and SBM.
2. Recovered drilling fluids increased by 30%~50%, greatly reduces the discharge of drilling fluids. Per the drilling speed, the recovered drilling fluid is around 3 cubic meters per day. And the cost in transporting the waste will be greatly reduced.
3. Saving the cost in placing a High G force drying shaker on site, as the ViST vacuum shaker screen can make the discharged cuttings much dryer. The installation design will not need any extra area onsite.
4. By using the ViST vacuum shaker screen system, the mud engineer can put finer screen on the shaker which and separate the much finer cuttings.

Sorry can not reveal all the principle details, or release a handbook, now it is operating in a few sites, hopefully will be more and more. If you wanna join,  please feel free to contact with GN.

GNZS703E is a 3-panel single deck shale shaker with linear motion. The shaker model is designed and made by GN leading solids control manufacturer – GN Solids Control. GNZS703E is the latest design of GN 3 panel single deck shaker.

Applications of GNZS703E shale shaker

1) The shaker can be used for oil and gas drilling, used as the first step solids control equipment.

2) The shaker model can be used in compact mud recycling system for horizontal directional drilling (short name: HDD), water well drilling, coal bead methane (also called CBM drilling).

It can also be used in other underground construction system as pre-separation, to remove the solids.

GN shale shaker

Extended models of GNZS703E shale shaker per different feeding type

Option 1 is top feeder; relative shaker model is GNZS703E-DZ.

It is designed for oil and gas drilling field. As in oil and gas drilling field, the dirty mud from well head will be transferred by pumps through pipelines. They do not use mud pit for storage. And mud pumped from well head will flow to the shale shaker feeding box through the pipelines and fall down directly to shale shaker under the gravity.

In this case, the back feeding type can reduce the height for feeding.

Option 2 is back feeder. It is specially designed for HDD and water well drilling.

As in HDD, CBM or water welling drilling, the system is compact and mud tank will not be big side. Top type feeding shaker is with a smaller footprint. East for layout.

In this kind of drilling, there is commonly a mud pit around the drilling rig. The dirty mud from well head will be pumped to mud pit first , and then transferred to mud system shale shaker by a slurry pump.

Other application of GNZS703E shale shaker

The shale shaker can be combined with desander cone assembly and/or desilter cone assembly to used as desander separator, desilter separator or mud cleaner.

GN Solids Control centrifuge is high quality with reasonable price, centrifuge operation is also very important. And it require operator with many years experience or with training certificate from professional centrifuge supplier. In many cases, centrifuge problem is because of non-professional operation, not centrifuge itself.

For example, one centrifuge is used for treating the mud after vertical cuttings dryer. The mud discharged from vertical cuttings dryer is very heavy mud with high density, viscosity and not good flowability. In this case, if you feed the centrifuge directly, the feed pump will not work well and the centrifuge is easy to trip off. Our suggestion is the client can design one holding tank between the vertical cuttings dryer & the centrifuge, install one agitator in the mud tank to suspend the drilling mud and adding water if necessary to lower down the density of the mud. The centrifuge will surely working very fine under professional operations.

Another, vertical cuttings dryer block and trip off sometime, why?  This is self protection of the vertical cuttings dryer when faced with wrong operation. We recommend the engineers to select the proper material for dryer. For example, it is not good to use vertical dryer to treat the mud waste discharged from mud cleaners & centrifuge. Because the separation point of the vertical dryer is about 0.5mm; however, the particles discharged from mud cleaner & centrifuge is much smaller than 0.5mm, around some hundred microns or even smaller than 100microns. In this case, the vertical dryer screen basket is easy to block, not good performance. The vertical cuttings dryer is very picky, it can only treat the drilling cuttings discharged from shale shaker.

Except for centrifuge and dryer, other equipment like shale shaker, mud cleaner, agitator, centrifugal pump is much easier operation. The shaker have to use proper deck angle and replace the shaker screens when necessary, mud agitator need to add gear oil for the gearbox, the centrifugal pump also need lubrication oil. Pls follow the instructions on label or user manual to do correct oil lubrication.

Generally speaking , the shaker screen on the shaker will separate solids the that larger than it’s screen opening size and retain the drilling mud and smaller solids .When 50 percent of solids size being found in the underflow of the shaker screen and 50 percent of the solids of that size found in the over flow , that size is call D50 or 50% cut point . The cut point is a graphical representation of the actual measured separation of drilling solids made by the shaker screen . For example , a D20 cut point will be the size where 80% of the solids particalsiin that size that returned to the drilling mud through shaker screen and 20% of the size solids separated by shaker screen .

Shale Shaker for UAE

There are several reasons that may cause a shaker screen performance failure . Most of the failure result from the improper shaker screen installation or damage on the shale shaker . The crack or warp shaker bed may result from to long time of continuous use or improper maintenance which will cause poor vibration patterns . To achieve max screen life , all the tension bolts must be operating properly . If early screen failure occurs , please check and make sure that one or more of the tension bolts are not missing and keep sure they are tightened correctly as per manufacturers recommendation .

Another possible cause of the improper solids conveyance , and then , screen wear is the linear motion vibrators running in the same directions , which will cause an improper vibration pattern , the result in massive amounts of solids accumulating on the first screen ,causing them to wear quickly . This can easily be remedied by reversing the electric wiring to the motors and vibrators of the shale shaker should be tested before spudding the well .


GN Solids Control sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , screw pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge.etc. Welcome you contact GN group freely.
