Water well drilling rigs are widely used for oil and gas drilling field, for normal lifetime and for industries.
Take the oil and gas drilling for example, water is the necessary material for drilling activities. Water is request to for drilling fluids mixing, for tank cleaning, for flush, for equalizing well pressure, etc… There will be different people involved for drilling activities; Water is also the essential material for the rig peoples. The rig sites are normally far away from human area. Well well drilling is the most fast and most convenient way for the water supply.
GN Solids Control engineer just came back from a middle east job site. He finished the first time commissioning and training of 1 set GNMS-500G water well drilling mud system. The 500GPM mud system is design and made for their oil rigs.
The system is composed of a single deck linear motion shale shaker, a hydro cyclone desilter separator, a drilling fluids mixing system, feeding pump, mixing pump, the explosion proof electric control system, trailer skid mud tank and electrical lighting systems.
For a compact design, GN put the feeding pump for hydro cyclone desilter, and the mud mixing pump on the skid.
In order to get a bigger usable capacity, GN designed the mud tank with 3 m width. Not only in China, but also in many other countries, 3 m is the normal width limitation for inland shipment. GN make all the sand gates build-in type. In this case, it will not over the tank width scope.
Clients request a mobile unit for fast movement. In order to save the cost of clients, GN Solids Control recommend client to source trailer skid locally and buy complete mud system from GN. GN Solids Control customize the system suitable for trailer skid. There are container corner blocks at each tank corner. The tank can be out and locked on the trailer skid like a container.

Decanter centrifuge and vertical cuttings dryer are the main equipment for drilling waste management. After many years’ running in different jobsites, GN Solids Control has good understanding on the drilling waste decanter centrifuge and vertical cuttings dryer.
Big bowl decanter centrifuge is widely used to treat the drilling mud and drilling cuttings. GNLW553C-VFD is a big bowl decanter centrifuge with 22’’ bowl diameter. As one of the main equipment from GN Solids Control company, it is designed and made per the latest technology. GN company can offer the big bowl decanter centrifuge with good price and top quality.
Features of 22’’ decanter centrifuge, model GNLW553C-VFD
The GNLW553C-VFD high-performance centrifuge is supplied with a 18 inch diameter bowl. The centrifuge model is with a length over diameter ratio of 3.4 : 1.
The centrifuge is fitted with a 75hp main drive motor and a direct coupled 30hp back-drive motor. The main drive motor and back drive motor are mounted at one end of the centrifuge. This design can minimize the centrifuge footprint.
The explosion proof motors and control panel can be certified to use in ATEX Zone 1 / Zone 2 hazardous locations, IECEx Zone 1 / zone 2 hazardous locations, CNEx Zone 1 / Zone 2 hazardous locations. For different EX certificate, price and leading time are much different. Clients can choose the suitable EX standard per the jobsite request.
The GNLW553C-VFD decanter centrifuge is fitted with main bearing temperature and vibration sensors which give the GNLW553C-VFD improved levels of safety and performance monitoring features.
Usage of 22’’ decanter centrifuge, model GNLW553C-VFD
The big bowl centrifuge is for removal of low gravity solids from the fluid system at reduced operating costs.
1) The big bowl centrifuge can be used to treat water base mud and drilling cuttings

Diamond drilling is an important division for GN Solids Control. GN Solids Removal Unit is specially designed with compact tank system for mobilization.
The Solids Removal Unit includes a mini GNZS752 Shale shaker, and a baby size decanter centrifuge GNLW223 (9 inch) centrifuge, and the decanter centrifuge feed screw pump, as well as the mud tank and mud mixing pump and shearing hoppers.
The GNZS752 shale shaker is made for removing coarse particles in the drilling fluids and, the GNLW223 decanter centrifuge is for cleaning fine solids in the drilling fluids. After treatment, the drilling fluids can be used for drilling again. This saves money for preparing new drilling fluids, and also it gives an environmental friendly jobsite.
Diamond drilling is different from other drilling, the diamond core drilling needs a small handling capacity solids removal unit, but also it needs to be very compact for transportation, and small foot print for set up.
The mud tank is for storage of drilling fluids, and the mud mixing pump and hopper is for adding chemicals to the drilling fluids.
The GN Solids Removal Unit can be put into a 20FT container for international shipping, and GN solids control provide commissioning service and training for the clients to operate the equipment. What we offer the clients is a turn-key solutions for handling the drilling mud.
With our worldwide partners and USA, China, Russia branch, we support our solids removal unit all around the world. Besides the solids removal unit, GN also have the oil gas drilling solids control system, No dig mud recycling system, TBM and bored Piling desander plants. GN Solids Control focuses on the liquid and solids separation solutions.
As the first API certified solids control company in China, GN Solids Control is your reliable supplier for Solids Removal Unit.

As more and more governments issued more and more strict regulations on the envornment protection, drilling waste management equipment becomes more and more necessary at drilling rig site, especially at oil and gas drilling rig site. As the drilling fluids contents various kind of chemicals, if discharged directly. it will have very bad pollution to the environment.
GN Solids Control latest design drilling waste management equipment drill cuttings solidification unit are welcomed at jobsite.
1) The drill cuttings solidification unit can be used to treat drilling cuttings discharged from the high G drying shaker. When the cuttings from solids control shale shaker, desander, desilter treated by high G drying shaker, the fluids will go to drying shaker catch tank for further treatment, the solids from high G drying shaker can be treated by drill cuttings solidification unit.
2) The drill cuttings solidification unit can be used to treat drilling cuttings discharged from decanter centrifuge. The liquid phase will be covered by further treatment, like dewatering unit. while the solids phase can be treated by drill cuttings solidification unit.
3) The solids discharged from vertical cuttings dryer can be further treated by drill cuttings solidification unit. It can reduce the water content in the waste.
Many clients may wonder, what is the water content after the drillings treated by drill cuttings solidification unit? It is not easy to see what the water content is. As it is flexiable. It is controlled by the operators. If you want to make the cuttings dryer, you add more chemicals, if you do not need very dryer, you can reduce the quality of chemical.
Features of GN latest design drill cuttings solidification unit
1) Small footprint with high efficiency of GN latest design drill cuttings solidification unit.
2) Automatically control of GN latest design drill cuttings solidification unit.
3) All the screw conveyers of GN latest design drill cuttings solidification unit are variable speed control.
