It is just another set of solids control equipment to Russia, but also not quite, collecting feedback, improving details, or do small customisations, that is what we always do.

After a whole day packing and marking labels, GN just shipped out one batch shale shakers and decanter centrifuges to equip the oil well drilling rigs in Russia. Shale shaker and decanter centrifuge are two of the key equipment in drilling mud recycling system. The shale shaker separates the cuttings by using the wire mesh screen opening size to block the coarse cuttings, while the decanter centrifuge is separate ultrafine solids by using centrifugal force.

GN shale shaker could be used in drilling mudsolids control system as the primary shaker unit and also as the high G force drying shaker in waste cuttings management system.
Below features make GN shale shaker the reliable performance in using
1. Shaker vibrating deck is completely heat treatment for higher vibration G force
2. Shaker is installed with GN self-produced composite frameshaker screen with longer working time.
3. Patented rubber sealing installation method make the replacement of rubber strip much easier and better sealing performance.

GN decanter centrifuge could be used in drilling mud solids control system for fine solids separation like the suspending barite recovery and useless cuttings removing. In the waste cuttings management system, the high speed decanter centrifuge could be used to treat the effluence discharged from the cuttings dryer. Besides the petroleum industry, the decanter centrifuge is also widely used in mining and environmental protection industry.

The decanter centrifuge shipped to Russia in this order is the popular 14 inch model with designed maximum speed up to 3900RPM. It could be control as fixed speed or variable frequency. 
Below features make GN decanter centrifuge excellent performance.
1. Bowl material is from duplex stainless steel 2305 with good machinability. 
2. Centrifugal casting technology makes the bowl material distribution evenly for a good dynamic balance. 
3. Tungsten material tile or bushing protection at abrasive part for longer working time and less maintenance. 
4. PLC control panel is available, and the sensors could be put on the centrifuge unit to monitor the status of the machine.

It has been a scar for lots of Chinese people, as it is bad reputation for made-in-china, and the pity part is there were actually lots of profiteer actually manufacturing bad quality products, so about 10years ago, when my client told me, they have never known a door handle is a draft iron ball, Im very embarassed, when an Chinese engineer from our client’s company emailed us to warn us to take care of the quality, we know we should make it right. So we did it, we focus on top quality products, and keep improving.

This year in Bauma, saw lots of hydraulic parts, gear supplier, which reminds me years ago, another client told me they can not find even one good hydraulic parts in China, I hope they do find one now. If not, I doubt they did not try hard enough, or did not pay reasonable enough.

There are many Chinese machine brands like Zoonline, Sany etc are doing pretty well, have their name internationally. You know when your clients, your friends tell you that they are proudly telling you they are using a Chinese brand, you know that is a comfort, that is a proud.

Also it is very good to find that more and more oversea companies are cooperating with local partners here to do local business, which means now it is not just admiringly use a good foreign brand, but also cooperating & competing.

For being quite a long time, the HDD mud recyling is just screening, or add some cyclones; though it is common sense for everyone sometimes that corroct sized combination of equipment can ideally targets drilled solid of different particle sizes from large drilled solids through to sand silt, clay and colloids; the decanter centrifuge cost money. While it get rid of 5~10 micron solids.

Decanter centrifuge have been approved for oil gas and lots of big HDD projects, that it works, save downhole tools life, and reduce the disposal costs. Then the topic comes to after the desilter cyclones, is it still worth to have a decanter centrifuge. Real conflict thing is until you use a decanter centrifuge, you can find out the real value in it.

Very recently GN have delivered a mud recycling system to Sinopec projects, with a decanter centrifuge. Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifuge is fixed on a collecting tank with 4 supporting legs. Liquid is flow into the tank and solids will be collected by the screw conveyor and transferred out of the system.

If you would like to know more info about the decanter centrifuge for HDD projects, pls let us know.

HDD Mud system is also one of the main business from GN Solids Control, for quite a while, that is how we made ourselves different, we make compact HDD mud systems for different clients, flexible to customize, and with more and more experience, now we got several standard systems meet most of the requirements. Recently we sent out 3sets of HDD mud recycling systems.

Two Sets 500GPM Trenchless Mud Recycler for HDD Company in India, and 1 HDD Mud Recycling and Dewatering Unit for Sinopec. A standard self-contained trenchless mud recycler is consisting of mud recycling equipment, mud mixing equipment and mud collection tank. Different from the mud recycler in oil gas drilling industry, the trenchless drilling will discharge the dirty mud back to mud pit on the ground firstly, then use a vertical installed submersible slurry pump to transfer the mud to mud recycler system.

1. Shale shaker GNZS703F is the first stage separation equipment to remove the coarse solids. GNZS03F is the latest version shale shaker in GN production line. This model shale shaker is with 3 panel composite frame shaker screen that is fastened by using ratchet spanner, easily and fast.

2. GNZJ703F-1S8N mud cleaner is combination unit of desander and desilter. The mud cleaner under shaker is the same model GNZS703F. Normally, GN use same model shale shaker for easy future maintenance. 2 units centrifugal pump are equipped in the system for feeding the drilling mud to the hydrocyclone units for smaller sand and silt separation.

Most of the driller will use Three-stage separation procedure as shale shaker, de-sander, de-silter to remove the cuttings and waste solids step by step. This is a cost saving configuration. If higher separation request is needed, the driller will bring a decanter centrifuge into the trenchless mud recycler

Decanter centrifuge GNLW363C-VFD is last stage separation equipment for fine solids separation. After several time recycling, there will be much fine solids in the drilling mud. The centrifuge is used to remove the fine solids to ensure the property of the drilling mud. Decanter centrifugeis fixed on a collecting tank with 4 supporting legs.

ViST have been a new product, with GN patent, and tested on site, comparing with similar products, now more orders on the way. This time the client purchased 6sets for an offshore project.

Due to the limited area, the mud recycling equipment on offshore platform is always with compact structure and high efficiency. The used drilling mud and waste cuttings coming from offshore platform normally will be barged to land for treatment. Thus, to maximally recover the drilling fluids will greatly reduce the time and fund cost in treating the waste cuttings. GN VIST vacuum shale shaker can greatly increase the volume of recovered drilling fluids.

Though so far GN ViST is only designed for GN shakers, and integrately with our own shaker in a very good way, we keep the flexiblity of putting this into all other shakers. The hopper design and connection of hopper to the vacuum unit is quite flexible.

GN ViST vacuum shale shaker is a shaker unit with a vacuum suction hopper installed under the last shaker screen. Shale shaker is the beginning of the mud recycling system, and drilling cuttings discharged from the shale shaker are always very wet with large content of drilling fluids. High recovery rate of the drilling fluids will greatly reduce the cost on cuttings treatment and new drilling fluids making. The ViST vacuum unit connects the shaker via a collecting pan under the last panel shaker screen at the cuttings discharge port. When the drilling fluids passes through the shaker screen, the vacuum unit will make a negative pressure to suck the liquid into the collecting pan, and then to the vacuum unit.

Benefit from ViST + GN Shaker

1. GN Screens compliant with API 13C, only supplier here in China certified by 3rd party

2. Hopper equiped onto shaker before it leave factory

3. Waranty & guarantee is for the whole unit. When if needed, shaker need to be modified to fit the hopper, someone may question the shaker waranty. If all from OEM manufacturer, no such problems.

Been a long time this site only introduce GN products, new projects, what GN have been R&D, have been upto. Well as time goes, when we reach more and more people, we realize it is also very important to know the culture, the custom etc. People think and live in a different way.

Falling on the 15th day of the 8th month according to the Chinese lunar calendar, the Mid-Autumn Festival is the second grandest festival in China after the Chinese New Year. It takes its name from the fact that it is always celebrated in the middle of the autumn season. The day is also known as the Moon Festival, as at that time of the year the moon is at its roundest and brightest.

Mid-Autumn Festival is an inherited custom of moon sacrificial ceremonies. The ancient Chinese observed that the movement of the moon had a close relationship with changes of the seasons and agricultural production. Hence, to express their thanks to the moon and celebrate the harvest, they offered a sacrifice to the moon on autumn days.
Nowadays, more and more people talking about stories, when you are selling your products, your service you are not selling these themselves, when you tell your client good stories, they understand what they will do what they will live or live with in future lives.

Actually all Chinese festival also based on stories, Chang E is the main charactor in this Mid Autumn festival.

As for GN Solids Control, our main goal is with our equipment, help people on drilling industry & environmental protection industry to improve the environment. With our name on all the relative equipment, live better life.

Also, to improve the perception of people about made in China, to know when you pay properly, you get very good product here in China.

Mud agitators is one of the most important equipment in the mud system, it does not matter if it is big or small, when you want to make sure the mud in the tank is active, mud agitator would be the right choice. Though still can use mud gun, in many different design, agitators are the most efficient option. Mud agitator and mud gun normally are used together, as mud agitator will agitate most of the tank volume, still the corner maybe missed, then mud gun will do its work, jetting the corner, and active them to the whole circulation.
Recently, GN finished the fabrication of almost 60 unit mud agitators and several unit vacuum pumps for a domestic client.
GN mud agitator is flanged connection type with compact structure. It is cost competitive and mostly used in the mud recycling system for mud mixing. In the mud system, mud agitator is installed in mud tank with stirring function to prevent the solid particles settlement down to the tank bottom. Another function is mixing to accelerate the dissolution of the mud materials. The mud agitator is mainly consisting of motor, gearbox, stirring shaft and impeller.
Vacuum pump is quite a new product, whist it actually was widely used in offshore projects, to transfer mud, sand, and doing tank sendiment transfer etc., nearly no restriction except the demand for air to drive it. GN has vacuum pump with flow rate of 40, 20 and 10 cubic meter per hour for client to select. For easy and continuous operation, GN vacuum pump can work under automatically mode.
GN keep doing R&D on different products, different applications also keep investing on the existing market, to make better and more user friendly products, freely to get in touch.
