c. The shale shaker deck of GNZS703E shaker is made from stainless steel material for a better performance of anti-abrasive and longer lifetime.
d. The dumpling spring of the shaker is steel material internal for more stronger and better performance of vibration desorption. The spring external is protected with rubber sleeve to prevent fingers involved in during operation.    
e. The vibration model is chose from worldwide famous brand: Italy Oil or Martin.
2) GNZJ703E-8S desilter mud cleaner
It is the combination of a shale shaker GNZS703E and 8 ea 4’’ desilter cone assembly. The 4’’ desitler cone is made from PU material for long lifetime.
And the cone assembly is removable. In case needed, the Operator can bolt off the desilter cone assembly and mounted a feeder box and use it as a separator shale shaker.
3) Slurry pump 1 ea. In case mud maybe stocked in mud pit, a slurry pump is used as backup.
3) Mud tank 1 ea. The mud tank is equipped with container block for easy mounted and clocked on the trailer.

Oilfield screen shaker separator normally called oilfield shale shaker or screen separator. It is the first step solids control equipment used in oil field and other drilling activities. It is the necessary solids control equipment for mud systems, no matter for oil and gas drilling, HDD, CBM, TBM, or piling.

Per the motion type of screen shaker separator, there are linear motion screen shaker separator and balance elliptical motion screen shaker separator.  
Oilfield screen shaker separator is normally linear motion type. And linear motion screen shaker separator is the most popular and long history type. Linear motion is more reliable. It can suits more kinds of jobsite condition.
While Balance elliptical screen shaker separator is very limited with jobsite and mud condition. When there are big load of mud, or the mud fall onto screen shaker deck unequally, the motion will be damaged and the BEM shaker cannot be working well. Mud will be over flow.

Per shaker deck quantity, there are single deck screen shaker separator and double deck screen shaker separator. Double deck screen shaker separator can be used for scalping shaker separator. The top deck use coarse mesh screen for pre-separation, while the bottom deck use normal mesh wire screen per jobsite condition.

Per the difference of applications and G force, screen shaker separator can be divided into solids control screen shaker separator and drilling waste management high G screen shaker separator. Beside the application G force is different, for solids control screen shaker separator and drilling waste high G force screen shaker separator, the feeding type of the 2 screen shaker separator is also different.
Solids control screen shaker separator is normally use top type or back type weir feeder, or box feeder, while drilling waste screen shaker separator is use hopper feeding.
Solids Control screen shaker separator can be fed by slurry pump or fed directly from the rig manifold under gravity. While drilling waste screen shaker separator can be fed by screw conveyer or cuttings transfer pump.  

TBM is Tunnel boring machine, it is similar to piling. It is widely used for municipal construction, like subway, tunnel, etc… There are high content coarse rock particles generated during the process. It does not have high standard for mud quantity. No need separate to very small size. It request big capacity for a rough separation, like 120m3/h or 240m3/h mud systm.

Mud plant for TBM Tunnel boring machine

It is compact mud system with double deck shale shaker, and desander hydra cyclone above the shale shaker to used as a combination of mud cleaner. 10’’ Desander cone quantity varies from 1 ~2 for different capacity (120 CBM or 240 CBM). TBM mud system use steel frame screen (e.g. 0.3mm, 0.5mm, etc…) and desander cone. Desilter normally is not used in TBM drilling mud system.

TBM Tunnel boring machine supplier:

1) Akkerman Inc  for Trenchless Tunneling Equipment 

2) Alvenius Industrier AB (Sweden)

3) Associated Polymer Services Ltd Geotechnical and Tunneling Supplies 

CBM (Coal Bed Methane) is more and more widely used. As natural gas as a clean energy type become more and more polular.

CBM (Coal Bed Methane) mud system is similar to HDD (Horizontal Directional Drilling). Compared with TBM and piling, it has a higher request on mud quality.

Mud cleaning system used for CBM drilling:

1) Per different capacity, Shale shaker is single deck or double deck, and utilize shaker screen 2 panels, 3 panels or 4 panels.

2) Desander cleaner

3) Desander cleaner

4) Mixing machine

CBM (Coal Bed Methane) machine supplier:

1) Atlas Copco (America)

2) SCHRAMM (America)

3) Sany Heavy Industry (China)

Desanding plant for TBM and mud cleaning system for CBM us different. They are not changeable. Customer should specify the rig type before order. For any questions on compact mud system, you can contact GN group for solution.

GN Solids Control is world famous manufacturer for mud recycling system for HDD, CBM, piling, underground instruction, trenchless, dredge slurry separation, etc…
GN Solids Control also offers customized solution per customer’s condition. A customer request 500GPM mud system for HDD rig. Below are their requirements on equipment for the 500GPM mud system. GN Solids Control gives solution relatively to optimize the mud system for HDD rig:
1) Customer request on 500GPM mud tank dimension: Mud tank to same as 20 ft standard O.T. container.( Standard frame with container corners for transport on containers vessels and for quick lifting)
GN Solution on the 500GPM mud system tank dimension: It is no problem for exactly same dimension with 20ft container. But GN recommends the tank with a smaller width: 2000mm in order to put into container for shipment.
2) Tank compartment for the 500GPM mud system: Divide the 20 ft mud tank to three chambers – (1) Shale shaker chamber, (2) De-sander chamber, (3) Desilter chamber
GN confirms the 3 chamber of the 500gpm mud tank system
3) Customer request to install bigger shale shaker model GNZS594E with 616 GPM.
GN team confirms the big shaker for 500GPM mud system.
4) Furthermore, customer request install 2 Nos. of big power pump 6×5 centrifugal pump with 45 Kw motor.

And install big capacity mud cleaner (shaker + 2 nos. of de-sander + 12 Nos. of desilter) model GNZJ594E-2S12N with 1056 GPM capacity.
Per the big centrifugal pump and big capacity mud cleaner, GN engineer give solution that: connection shale shaker with mud cleaner shaker with distribution box, controlled by valve, customer can choose to use 1 shaker or 2 shakers. In this case, the mud system can extend to be with 500GPM capacity or 1000GPM capacity.
During 500GPM capacity, the user blocks half of desander cone and half of desilter cone for a better hydraucyclone separation.
5) Regarding mixing system, as customer already have some mud tanks locally, GN offers a separate jet mud mixer for option. Customer can chose it to match with its local mud mixing tank. Or connect the shale shaker tank with its original mud tanks.
The system is easy to shift between 500gpm and 1000gpm capacity. Customer is very happy with professional engineering team of GN Solids Control.
If you have interest on above 500 / 1000 GPM HDD mud system, or you have any special request on no-dig compact mud recycling system, you can contact GN group freely for more information.

Drill pipe is an industrial tubular used to drill into the ground. There are three major industries that use drill pipe. The most common application of drill pipe is in the oil and gas drilling. Another industry that uses drill pipe is the underground construction industry, or more specifically, the Horizontal Directional Drilling (HDD) industry. And finally, the water well drilling industry also uses drill pipe.

The oil and gas industry is where drill pipe is used the most. Another industry that uses drill pipe is the underground construction industry, or more specifically, the Horizontal Directional Drilling (HDD) industry. This industry utilizes drill pipe to bore tunnels underneath waterways, major roadways, and generally any place where trenching is not acceptable. The resulting bore is used for various utility pipelines such as: fiber optic, water, electricity, and oil and gas. HDD drilling rigs are very different from oilfield drilling rigs in that they are almost completely laying flat or horizontal. Most of the larger (Maxi) HDD rigs use exactly the same drill pipe that the oilfield uses.

HDD drill pipe have a variety of models. Different brand HDD machine have different drill pipe standard.  Usually, the length and thickness of the dill pipe are similar, but the thread of the connector are different.

Vermeer and Ditch Witch are the most 2 famous manufacturer for HDD drill pipe, while GN Solids Control is the most professional for HDD mud recycling system.
