A lot of clients are asking for ViST Vacuum Shale Shaker Screen Technology to GN solids control, now the technology is already available to sell, pls contact with GN sales engineer to get more information, and understand more from the video : http://www.gnsolidscontrol.com/vist-vacuum-screen

The basic technical specification is as below:

Applicable Mud OBM,SBM,WBM
Recovery efficiency 30%-50%
Mud Temperature -15 +85°C
Control System Air operated Automatic control
Time for Suction Adjustable per drilling conditions
Dimension (Weight) 840x640x1050mm ( 400KG )
Electrical Power No required, only need Air supply

Based on different site schedule, the installation of Vist vacuum shaker screen unit have 2 ways: 1) it is installed externally of the shale shaker, there is one pipe to connect to the last shaker screen of the shale shaker; 2) it is installed under the last shaker screen of the shale shaker when there is enough room.

The purpose to install the vacuum is to reduce drilling waste:
1) Reduce the volume of drilling waste, the drilling cuttings will be much drier, the fluids on the cuttings is reduced 30% to 50%, so the further drilling waste treatment cost is much cheaper, or the transportation cost of drilling cuttings is cheaper
2) Increase the drilling fluids recovery efficiency, save the cost to prepare new drilling fluids
3) Save the cost of the client to buy more equipments, such as drying shaker, shaker screens, vertical cuttings dryer, etc, also save the space to install these equipments
4) Save the power consumption of electricity, it can operate with the air compressor which is provided by the rig
5) Increase the shale shaker separation efficiency, also increase the solids control system efficiency, it can be used for all kinds of drilling fluids like OBM, WBM, SOBM
