ViST is Vacuum Screen Technology is to work with shale shakers to reduce drilling waste and recycle drilling fluids.
ViST was pending a patent design developed by GN Solids Control. GN tested ViST with drilling fluids. It proved to be very efficient for recycling drilling fluids.
The ViST Pan is installed under the last screen or mounted externally. And a suction hose is connected to ViST vacuum unit. The compressed air from the air compressor or the rig air supply is required to create suction on the last screen surface, pulling additional fluid off the cuttings. It can reduce the liquid on the cuttings by 30-50%.
As a result,ViST maximizes the volume of recovered and reused fluids and it provides dryer cuttings. Dryer cuttings mean less drilling waste and more recovery drilling fluids. So ViST can save money for operators on drilling fluids and waste management.
Features & Benefits
Widely application for OBM, SBM, and WBM.
Both onshore and offshore applications reduce waste and recovery fluids.
To replace High G drying shaker without any extra consumption of shaker screens.
Less footprint and easy installation without welding.
Reduce waste by 30% to 50%
A finer screen can be used to improve the solids control efficiency.
Less cost for drilling cuttings transportation
No electric power is required, suitable for work in Hazardous areas.
The suction and discharge time is adjustable according to different drilling conditions.
One ViST can be connected to 2 – 3 shakers with only one air supply
