shale shaker

This week GN shipped one set of workover rig solids control system to Australia. The configuration is as below:
1) Shaker tank with 2 units of shale shaker to clean the drilling mud


2) Mixing tank with mixing hopper, 2 units of centrifugal pump to prepare for new drilling fluids
3) Mud agitator, mud gun, pipelines, valves all equipped with both mud tanks
The difference for this solids control system between normal solids control system:
1) All the electric control system include cables, glands, electric components, and the design should be comply with Australia explosion proof standard
2) The lifting pad, walkway, handrail, the distance between adjacent components, etc should be comply with Australia safety regulations
3) The welding and painting standard is also very strict in Australia, the tank top surface is fixed with high strength glass fiber reinforced plastics.


4) The clean gate is with high position gate valve type clean gate for convenient operation and cleaning of the accumulated solids
GN design and manufacture the workover rig solid control system as per the client’s special requirement and Australia standard. This is not the first unit of solids control system shipped to Australia, we had sold over 30 units of mud recycling system for HDD industry.

One unit of 1m3/h oil sludge treatment system testing unit is shipped to Europe recently, this is for client’s urgent requirement, later the 15m3/h oil sludge separation system will be shipped next month for the same client.


The client has visited GN factory in Beijing twice, after factory inspection and business negotiation, they placed order for the 15 m3 oil sludge treatment system, and also the 1 m3/h oil sludge separation system for urgent purpose.
To check the working video of the 1m3/h oil sludge separation unit, pls check our website:

The main components of the system including:
1) 2 panel shale shaker to separate coarse solids from the oil sludge in case of any coarse solids will damage the decanter centrifuge
2) 2 phase mini decanter centrifuge to separate the fine solids maximumly from the oil sludge by mixing with chemicals, with fluids collection box
3) 3 phase disc centrifuge to separate the oil from water to get pure oil and pure water
4) Oil storage tank and water storage tank
5) Pre mixing tank with mud agitator, heating lines
6) Chemical dosing system
7) Shale shaker fluids storage tank with heating lines
8) Shale shaker feeding pump
9) Decanter centrifuge feeding pump
10) Tank skid for the all equipments

The system is originally produced to show at CIPPE oil exhibition, after the exhibition, we shipped the testing unit to a domestic client for testing their oil sludge treatment, they use the proper chemical jetting and get the satisfied result, then we shipped the unit back to our factory for cleaning, and prepare to test in other client’s jobsite.

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:
Item Specs
Supply Air Pressure 0.7-1.0Mpa (100-150PSI)
Air capacity required 4.5 m³/min (160 CFM)
Operation Shaker For 2 -3 Shakers
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

Recently GN solids control shipped 8 sets of shale shaker without vibration motor shipped to our clients, the client will install the vibration motors by themselves who had installation capability. This is not the first order from this client, they repeat orders because they are satisfied with the working performance of GN shale shakers which they ordered before.


Shaker deck is the most esscential components for a shale shaker, the bottom material treatment before painting, we owns our ball blasting machine, the ball blasting degree is 2.5 with working life 10 years more, we can control the bottom treatment quality better, unlike other solids control manufacturer in China, they use sand blasting which is provided by third party supplier. 3 layers painting and coating by choosing Japan Kansai or US ppg brand painting, to promise the shaker deck not to get rusty and abrasion during the operation. In some tenders, it required the complete the shaker deck( all the vibration and non vibration components) are made of stainless steel material, it will increase the shaker production cost a lot and the the client has to pay more money.


The deck bottom of GN shaker is made of stainless steel material, and the unique rubber sealing technology to ensure the reliable performance of the rubber sealings, we also use GN own made composite material shaker screens, the working life is 2 times compared with the traditional steel frame shaker screens.

ADIPEC 2017 will be held in Abu Dhabi next week, this year as the oil price is recovering gradually and today the WTI price has reached up to USD 57 per barrel, we believe ADIPEC 2017 will be more successful than last year’s and will attract more and more attendees and exhibitors to attend the show, exchanging the ideas and share the latest technology in the oil and gas industry.


GN Solid Control is the advanced manufacturer for the solid control and waste management equipment and system. GN has been consistently attending the ADIPEC show for many years, and each year the customers will see GN’s growth and development. Now GN has become the one stop shop for all the solid control equipment, from shale shaker, decanter centrifuge, cutting dryer, to the various kind of pumps, such as centrifugal pump, screw pump, to the agitator, mud gas separator. GN not only make some new in equipment, but also make the great upgrade on the shale shaker screen. From the beginning of this year, GN has fully upgraded its shaker screen from the old steel frame screen, this will make much better performance and longevity that ever before. Also the new composite frame screen has larger non blank area and the processing capacity has been improved dramatically. And most of the screens are 3 layers, the wire mesh suppliers are the same as the other famous brand screens, such as the MI SWACO, DERRICK. If you are interested in this product, you could come to GN’s booth and take a look at it. We believe you will be impressed by the screen when you finally see it.
