ViST vacuum shale shaker

Recently GN solids control shipped one batch of the shale shaker, decanter centrifuges to Russia drilling rig. The client will produce the mud tank locally to save freight cost, import tax and save delivery time, and buy the major equipments from GN.


Shale shaker is the most important equipments and first phase cleaning equipment for oil drilling rig solids control equipments, the lastest model shale shaker is F version shale shaker. Compared with the previous version shale shaker, the features of F version shale shaker is as below:
1) Composite material frame shaker screen for longer working life, the screen mesh over API 60 all use 3 layers wire mesh for reliable quality.


2) The screen deck bottom is made of stainless steel 304 material for better Corrosion resistant, with 3 layers costing and painting with Japan Kansai brand or US PPG brand Marine anticorrosive painting.
3) Italy Oil brand vibrator or Itavibras or US Martin brand vibrator to meet client’s different explosion proof requirement。

Decanter centrifuge with 3200rpm high speed to separate the low gravity solids, after long period drilling, more and more fine solids will accumulate in the drilling fluids, which can not be separated by desilter cone and low speed decanter centrifuge, then the recovered the drilling fluids can not be reused to prepare for new drilling fluids, the user need the high speed centrifuge to reduce the solids content and separate the fine solids out. Normally they will use the low speed centrifuge before the high speed centrifuge for barite recovery, or they can use a VFD decanter centrifuge to use for both barite recovery and LGS if there is not enough space to install 2 centrifuges.
If you need major shale shaker, mud cleaner, decanter centrifuge for oil drilling rig, pls contact with GN solids control.

GN ViST vacuum shale shaker is a shaker unit with a vacuum suction hopper installed under the last shaker screen. The purpose to use the ViST vacuum unit under the shale shaker is for more recovery of the drilling fluids in the same conditions compared with shale shaker without ViST system, and the discharged drilling cuttings will be much drier, so the user can save cost to treat and disposal the drilling cuttings. Normally it is very difficult for the offshore drilling cuttings collection, treatment and disposal, sometimes client will ship them back to drilling waste management facility in land, the collection and shipment cost is very high, other clients use cuttings re-injection technology, some clients use Thermal desorption unit, some clients installed drilling waste management on the offshore rig floor, but normally the area for offshore drilling rig is very limit, it is hard to install a complete vertical cuttings dryer system. Because of these reasons, ViST vacuum shale shaker became very important for offshore.


As a professional solids control and drilling waste management system manufacturer in China, GN solids control, GN solids control keep developing new and advanced technology for oil & gas industry and provide the best solution for our clients.
Features of ViST Vacuum Shale Shaker


1. GN ViST vacuum shale shaker is suitable for oil based mud, water based mud and Synthetic oil based mud.
2. By using the ViST vacuum shale shaker, the drilling fluids recycling will be increased by 30%~50%, It greatly reduces the volume of drilling waste and the cost to transport the drilling waste.


3. By using this ViST vacuum shale shaker, no need extra high G drying shaker again; The compact design did not take much area at site.
