high G drying shaker

GN solids control just come back from CIPPE 2019 oil exhibition in Beijing, China. We showed our advanced technology and equipments at the CIPPE oil show. Below is the photos taken in our stand.


1) Sludge Vacuum pump: it is the ideal pump to transfer the waste cuttings, waste sludge, oil sludge, drilling mud, cement, powder material and other industrial waste.
2) High G force drying shaker with 4 panel composite material shaker screens. The screen dimension 585x1165mm, we can install the shaker screen with API mesh size from API 20 to API 325 comply with API RP13C. The G force is up to 8.0G.
3) 14 inch bowl decanter centrifuge
4) 22 inch bowl decanter centrifuge for waste water treatment and waste sludge treatment and dewatering unit, the bowl diameter is 550mm, the bowl length is 2310mm, different with the normal drilling fluids treatment centrifuge, the GNLW554 series centrifuge can treat the discharged water much cleaner, it is ideal centrifuge for the project required very clear water.
5) Oil sludge separation system : The configuration is as below:
The Premixing tank, coarse solids separation shale shaker, decanter centrifuge, three phase centrifuge, chemical dosing unit, fluids buffer tank, shaker fluids collection tank, oil tank, water tank and complete skid. The mud agitator and heating lines installed on the premixing tank.
6) Vertical cuttings dryer for oil based drilling cuttings treatment.
7) Screw conveyor to transfer drilling cuttings to vertical cuttings dryer drilling waste management system
We got a lot of inquiries and positive interests for the oil sludge treatment unit. The working video for the oil sludge treatment is as below: By using proper chemicals, we can design the customized system for different requirement. If you need to know more information, pls get the brochure from our sales engineer.

Recently GN solids control shipped vertical cuttings dryer, decanter centrifuge system to Russia drilling companies, they are installed inside the 40ft container to keep them warm and avoid frozen of the drilling cuttings when working in Winter.


The client use the vertical cuttings dryer system for oil based drilling cuttings, when they use water based drilling cuttings, we will use different system design with high G drying shaker and decanter centrifuge, and we have standard design of pitless system for both water based mud and oil based mud ( also for SOBM), the client only need to buy one system and use them in different rig site.
The VFD decanter centrifuge GNLW363C-VFD is the most popular decanter centrifuge used for solids control system and drilling waste management system, oil sludge treatment system, dewatering system, solids water separation system and waste water treatment system. The VFD control panel is positive pressurized VFD control panel with PLC smart control and HMI interface, the inverter for main motor, back drive motor and feeding pump motor are made of ABB or Siemens brand or Schneider brand for global outsourcing.


The bearing is SKF brand, the screw  is made of stainless steel with heat treatment up to 1000 degree, the impeller is protected by tungsten carbide tiles for longer working life and easily replacement. The mud distribution port and solids discharge port are all protected by tungsten alloy and interchangebale. The bowl material is duplex stainless steel 2205 or 2304 by centrifugal casting, it is much better than SS304 and SS316.

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.
If you are interested in GN ViST vacuum shale shaker, pls contact with GN solids control.

GN solids control shipped one unit of hydrovac excavation waste slurry treatment system to Canada this week. The configuration is as below:
1) Dewatering centrifuge modular:


One unit of 22 inch bowl decanter centrifuge with feeding pump, telescopic skid as dewatering centrifuge unit, it can work together with chemical dosing system by adding flocculant or chemicals. A fluids catching tank with pump is installed under the centrifuge fluids discharge port to collect the fluids discharged from the dewatering centrifuge.
2) Fine Solids Hydro cycling Separation Module


GN mud cleaner ( desilter cone with bottom shale shaker) separate the ultra fine solids by desilter cone with feeding pump, the cut point is 25 microns. The washing tank under the mud cleaner collect the clean slurry discharged from desilter, and the drying shaker recover more useful fluids and make the discharged solids much drier.
3) Waste Collecting and Washing Module


Firstly the waste ( composed of water, soil, large size trash and other mass) is delivered to the site by hydrovac truck and discharged to the large collection hopper, a bottom screen separate the large size trash from the waste slurry. After separation, the waste is collected by the mud tank under the coarse screen. The waste slurry is pumped to GN high G drying shaker to separate fine solids and reduce the solids content. The high pressure jetting device is used to flushing the screens to avoid the blocking of shaker screens and wash the slurry.GN own made composite material shaker screens for longer working life is installed on the shale shaker.
