GN Solids America LLC is one of the top machinery manufacture in China for drilling mud solids control and drilling waste management of the drilling cutting waste.  The shale shaker screen is most consumable part on whole drilling mud solids control process.  GN solids America’s shale shaker screen combine with exceed industry standard and aggressive sale price, it becomes most selling item among operators in the drilling field that perform drilling and/or waste management for environment protections.

GN Solids America LLC manufacture replacement screen for popular brands like Derrick, M I Swaco, NOV and Fluid System.  GN Solids America LLC also accept custom design order for screen as well among other brands and operators that have special need for operation.  While price and spec is exceed expectations of operators, GN Solids America LLC offer 2 type of frame materials for the shale shaker screen to satisfy operator’s operation objective.  Steel frame shale shaker screen is for price awareness operator while composite material frame shale shaker screen is for operation-effectiveness operator.  Both type of screen will filter the same index of solids that is in the drilling mud and/or other wastes.  . Composite material screen has better separating performance due to the shaker screen area is larger than metal frame screens. The steel frame shaker screens are very heavier while the price is lower than composite material screen.

GN solids America LLC’s main replacement shale shaker screen is for GN Solids America’s own shale shaker and mud cleaner and for M I Swaco’s Mongoose shale shaker.  The screen has offer both metal frame and composite material. Generally speaking, the using life of composite screen also last longer than the metal frame screens. GN’s replacement for NOV King Cobra series and  VSM-300 series screens also has those two materials can be chose. All shale shaker screen comply with the manufacturing standard of API RP13C, which the common standard for separating measurement.

As one of the most professional solids control and drilling waste management equipment for oil & gas drilling, we use a lot of electric control panels for our equipments, also for the drilling solids control system and HDD & CBM mud recycling system, even for the pressurized VFD control panel for the decanter centrifuge and vertical cuttings dryer. The delivery time, quality and design from the precious supplier( the top explosion proof control panel manufacturer in China )can not meet our high standard for our international client which should comply with our advanced equipments’ design, so we start a new workshop to produce our own electric control enclosures which with higher standard, better material, faster delivery time and user friendly design, especially for the electric components inside the explosion proof enclosures, we use world famous brand like ABB, Siemens, Schneider.

Actually we start to produce GN solids control own brand electric control panel and positive pressurized VFD control panel several years ago, GN produced VFD control panel for decanter centrifuge and vertical G dryer with the features below:
1) 100% stainless steel material cabinet with 3 motor VFD( main motor, back drive motor and pump motor), sometimes we produce carbon steel material VFD control panel when the client required a cheaper unit because of their budget
2) World famous electric components, the client can replace the part locally, like
ABB, Siemens, Schneider.
3) Pressurized VFD control panel instead of normal Chinese explosion proof control panel for better cooling and performance under high temperature, air conditioner is for option for extremely hot area as the client’s special request
4) PLC smart control with touch screen, HIM automatically control the frequency, speed, differential speed, etc.

5) Compact design, container shipment, telescopic skid is available to install the VFD control panel with the centrifuge in the same skid for convenient transportation.

All drilling functions are similar in some aspect such as drilling when one is re-decorating the house and laying the actual pipelines for the water along with electricity inside home, we all use a drill and utilize water as media. The particular function of the water the following is to protect the drill bet and when the water is out, the particular some particles from the wall structure come out with the water. Of course , all of us don’t need to reuse the little amount of water and just remove the dirt away.
To get other drilling projects resemble, just a little bit or more complicated. As the earth’s composition is more complex than the wall and much more hazardous, so when drilling for the gas and oil wells to a certain depth, there has to be professional engineers to make the drilling mud as drilling growing media according to the earth condition plus the mud must be treated well, as well as economically after use in in an attempt to be ready for reuse.

GN Solids Control focuses on providing for those drilling projects the mud cleaning systems including:
one Oil and gas drilling mud systems including all 5 various phases separation, 4 actions solids control, with major equipment like shake shaker, desander, desilter, vacuum degasser, centrifugal pumps, submersible slurry pumps, shear pumps and also mixing hoppers, and also the decanter centrifuge and vertical cuttings dryer. In all, the complete brand for oil and gas solids control.
2 . Mud recycling devices for HDD and CBM. HDD and CBM drillings are also drilling works, the functional principal is similar. Comparing together with oil and gas drilling, HDD jobs need less equipment although comparing with other drillings, HDD need more. GN has typical designs for HDD drillings for different treating capacities.
a few. Other drillings and building works like TBM, h2o well drillings and mining or prospecting.
May you need more information or even need some suggestion for selecting suitable mud recycling system, pls contact GN to find out more.

As we all know, GN decanter centrifuge mainly used for drilling fluids/ mud treatment in the past years, we are developing our centrifuge for other different applications, the new applications are as below:

Dewatering sludges / mud and suspensions
Thickening sludges or mud
Clarifying different type liquids
Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase
Classifying solids in a wet suspension by grain size
Separation of solids according to various densities
Our decanter centrifuges can be used for both oil & gas drilling mud and none oil drilling mud, the function is to separate solids from the liquids, to keep the drilling fluids balanced, and reuse the drilling fluids to prepare for new drilling mud.
According to client’s feedback at oilfield rigsite for drilling waste management, GN decanter centrifuge can help them to reduce the water content efficiently from the drilling cuttings discharge, and reduce the fine solids from the drilling fluids ( mixed with water and oil), the next treatment step is oil water separator. The separation cut point is up to 2 microns, and after using the dewatering unit together, the cut point is up to 1 microns. Our decanter centrifuge is also used to barite recovery at low speed 1800~ 2200rpm, and low gravity drilling fluids at high speed 2700 rpm~ 3200rpm, and dewatering unit at 3200 rpm ~3900rpm.

GNLW series horizontal screw type decanter centrifuge is a leading design of function of decanting centrifuge.   GN Solids America LLC’s decanter centrifuge is the final process steps equipment in drilling mud cleaning system for solids control and drilling mud cleaning. The superiority function of decanting centrifuge is embodied in the solids size processing. GN Solids America LLC’s decanter centrifuge could remove the solid particles with size 2-7 microns using the principle of centrifugal force produced by the decanter centrifuge.

The choice of horizontal screw decanter centrifuge is important because it related to the whole mud cleaning work efficiency and operation cost of the drilling rig.  The facts need to be considering are list in below:

1 .The RPM of the decanter centrifuge for separation.   General horizontal screw decanter centrifuge can rotating RPM is 1800 to 4000 depends on the size of the Bowl. The higher the RPM speed, which leads to higher the separation of solids

2. Centrifuge parts materials: Different kind of material have its wear-resisting, corrosion resistance and other physicochemical indexes. GN Solids America LLC’s decanter centrifuge general minimum material is made of 316L of steel. The abrasive elements must use ceramic composites.
3. The controlling difference of the centrifuge: Difference in control effect accuracy of the differential, and the life and maintenance costs of decanter centrifuge. The higher the differential speed, the better the adaptability of the material, it is appropriate to use the device with high accuracy and high speed.
4. Diameter length ratio: the diameter/length ratio of horizontal screw centrifuge means the greater the processing capacity, the smaller the moisture content.
5. Control system: whether it is VFD programming control or fixed speed control, the decanter centrifuge manufacturers have basically produce the full VFD automation control of the machinery or fixed speed machinery.
6. Processing of the drilling mud: the horizontal screw decanter centrifuge is a high precision machining requirements of the solids separation equipment, not with the ability to produce high product maintenance, processing capacity is limited.

Hebei GN Solids Control Co., Ltd is leading manufacturer for drilling mud solids control & drilling waste management equipment and shale shaker screens. Besides as the top one in solids control field for oil and gas drilling, Hebei GN Solids Control Co., Ltd is also the top one in mud cleaning and mud recycling systems for Bored Piling, Horizontal Directional Drilling, Tunneling and so on. Take GN 500 gpm mud system as an example, GN has 4 standard models with different equipment for different kinds of drilling activities.

Recently GN delivered a new designed solidification unit to our domestic client, it has been improved based on the previous design with the bigger storage capacity for solidification agent, flushing system, stronger mixing unit for heavy duty operation.

According to the feedback from the client’s rigsite, the storage capacity of chemicals is not big enough for drilling waste with more fluids, so the solidification agent storage box is bigger in the new design, so the new solidification unit could be used for multi drilling waste status- with more fluids content or with less.
Another change on the new solidification unit is the feeding hopper skid, the feeding hopper is much bigger than the previous stabilization unit, we consider the international container shipment cost, the auger could be disassembly during shipment and the whole solidification unit could be shipped by a 40 ft container.
Solidification unit is an economic way for drilling cuttings disposal when the fluids content is not too much, if the environmental laws is permit, but in some countries, solidification unit is not acceptable for environmental laws. Too much solidification agent cement and calc will be wasted and the cost will be higher compared with the performance.
Except for solidification unit, GN solids control also provided drilling waste management system, Thermal Desorption Unit, dewatering unit, vacuum unit, Screw conveyor, decanter centrifuge, vertical cuttings dryer, high G dryer shaker, Mono pump, etc. Solidification unit and dewatering unit, decanter centrifuge and high G dryer is normally used for water based drilling cuttings, vertical cuttings dryer system is normally used for oil based drilling cuttings.
We will keep improving our solidification unit according to the feedback of our clients, user friendly and the performance is our target to make our client satisfied.  For more information of drilling cuttings disposal, pls contact with GN solids control.
