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.

Unfortunately most of the HDD machines in India did not have a mud recycling system to reuse the drilling fluids, it is a huge loss of the HDD contractors that who never realized the importance of mud recycling system for HDD machines. You may own HDD rig made in USA, or you have HDD machines coming from China, whatever type machine you have, the mud recycling/ cleaning/mixing system can help you in the points below:

1) Reuse the drilling fluids or use the recycled mud to prepare for new mud, reduce the drilling cost
2) Lubricating the HDD rig
3) Cooling function
4) Reduce the drilling waste and only a small mud pit is required in the site, especially for some countries which have strict low for the drilling wells and drilling waste disposal, a mud recycling system can reduce the waste volume and make it easier to treat the waste properly.
5) Reduce the damage of the HDD machine and you can use it for longer time
At the beginning it is hard to convince the client who never used such mud recycling system for HDD projects to use it, he may ask why I should invest so much money for the mud recycling system. I can just leave it in the mud pit, it will be useless for me, etc. We have to show the client the successful case study of their competitors who began to use mud recycling system, they did job perfectly and fastly, the investment will be changed to profits in the future.

GN solids control provide mud recycling system for HDD machines Vermeer, drillto, America Auger, etc. We have different treating capacity design for options, 200gpm, 300gpm, 500gpm, 800gpm, 1000gpm, each mud recycling system with different storage capacity. The mud mixer could be included.
