The one mud tank design is to meet the client’s requirement to replace the old shaker tank, and the remained part of the existing solids control system is still in usage. All the necessary connection dimensions can fit with each other through good communication with clients. The explosion proof electric control system is equipped to control all the electric motors in the system and the big motors are controlled in the MCC at client’s rig site.
Features of the solids control system:

This week GN solids control shipped three containers of shaker screens to America warehouse, every month GN will ship thousands of shaker screens to Houston, USA to sell to our clients in North America and South America.


GN solids America is the branch company of GN solids control in Houston, USA, we have various models shaker screens stock in the warehouse, including:


Composite material frame replacement shaker screens of Mongoose shaker, dimension is 585x1165mm, all the API size higher than API 60 use 3 layers SS 316 wire mesh, the composite frame last longer than traditional steel frame screens, not easy to get rusty, it can be storage up to 5 years, and the effective screen area is 20% larger than steel frame screens.


Composite material replacement shaker screens of Brandt Cobra family screens, Venom screens, VSM 300 primary screens, VSM 300 secondary screens
Composite material replacement shaker screens of FSI shaker
Except for shaker screens, GN solids America also have linear motion shale shaker, linear motion mud cleaner, decanter centrifuge, vertical cuttings dryer, centrifugal pump, and spare parts in stock there for immediate shipment. All the equipments motor and control panel with IEC explosion proof certificate, which is acceptable in America.


If the client need a customized solution for HDD mud recycling system, oil sludge separation system, drilling waste management system, solids control system, vac hydro slurry treatment solution, pls contact with GN sales engineer. We can provide solution for all the applications for liquid and solids separation.

This week GN solids control shipped one unit of HDD mud recycling system and dewatering unit to Sinopec project. HDD is one of our major applications, GN equipments 4 major applications including oil & gas industry solids control system and drilling waste management system and oil sludge separation system, HDD & CBM industry mud recycling system, Piling & TBM desander unit, Industry waste water treatment.


The technical configuration is as below:
1) 3 phase cleaning mud recycling system mud tank, with containerized frame for convenient transportation, the user can put the mud tank and the frame with equipments on the trailer and move to another site from one site.
2) 1 unit of GNZS703F shale shaker as the first phase cleaning equipment, equipped with 3pcs of durable composite material shaker screens with customized API mesh screen. We produce OEM composite material shaker screens from API 20 to API 325 as per client’s requirement.


3) 1 unit of GNZJ703F-1S8N mud cleaner, with under flow shaker, desander cone and desilter cone combination unit. Equipped with 2 units of centrifugal pumps as feeding pump of desilter cone and desander cone.
When the drilling fluids temperature is over 70 degree, we will use special material hydrocyclones for longer working life.
4) Dewatering system with same dimension mud tank
5) Decanter centrifuge GNLW363C-VFD is the 4th stage cleaning to separate fine solids smaller than 15 microns. After several years working, more and more fine solids are accumulated in the tank bottom, these fine solids can not be separated by the desilter cone, then high speed decanter centrifuge is required to clean the drilling fluids, otherwise it can not be reused for drilling again.

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.

As the leading company in the solid control industry, GN solid control can manufacture not only the good quality solid control equipment, but also can make great mud recycling systems. This system is with full stages of solid control equipment and large liquid storage tanks. Since its establishment in 2007, GN has already started manufacturing the solid control equipment for the oil and gas industry. After 10 years development, GN has already accumulated much experience and can be customer’s one stop shop for solid control system. Now its product range spanning from mud cleaner, cutting dryer, shale shakers, decanter centrifuge, vacuum degasser, various kinds of pumps and so on.


The mud recycling system is mainly composed of the following elements: there are 14 tanks in total used for mud recycling, storage and mixing and for water and fuel storage. There are 3 units of shale shakers which will be connected to the mud distributors that will distribute the drilling mud coming through the pipeline from the wellbore. There is also a mud gas separator to eliminate the flammable gas for safety purpose. And after the shale shaker, there is one vacuum degasser which will be used to remove the cut in gas in the mud to improve the efficiency of the centrifugal pump. After that is one mud cleaner which is composed of desander, desilter and underlying shale shaker. One decanter centrifuge is also equipped in the system for barite recovery. This can save the operator a lot of money as barite is very useful and expensive. There are also various pumps installed in the system to perform their function, such as the centrifugal pump which is used to transfer the drilling mud in the system. And there are also about 30 units of agitators and mud guns which will be used to clean the corners of the tank and mixing the mud in the tank to keep the mud property at good level.


That’s the brief introduction about the mud recycling system. Hopefully it will be useful to you. GN has many types of configuration for different mud recycling system for different HP drilling rigs.  Welcome to visit www.gnsolidsamerica.com and please send your inquiries to sales@gnsolidscontrol.com
