Mud treatment is required in many different industries.  For GN Solids, the most popular mud treatment is oil drilling mud treatment, or HDD mud treatment.  In recent years, we have more and more project from other industry mud treatment, like piling mud, TBM mud treatment, or construction mud treatment. One batch of mud separation equipment for US client, ready for delivery. The client will use the equipment to treat the construction mud.

1) High G drying shaker with catch tank

The mud will be collected by one big hopper with wide opening, and then transfer to high G drying shaker, to separate the big solids particles.

GN high G drying shaker is equipped with 4 panel composite material shaker screen or coarse steel screen per client’s request. The longer shaker deck can give better separation, and make the solids discharge as dry as possible. The super G force also very important to the dryness of discharge solids.

The high G drying shaker is seated on the catch tank with submersible slurry pump. The slurry pump can suck the mud and feeding to next unit for further treatment.

GN has various model centrifuges for option with different bowl size and different capacity, with different speed to separate different size particles.
1) GN 9inch baby centrifuge with only 9inch bowl size, and treating capacity will be 3-5m3/h. Normally, mining project / diamond drilling will require the small centrifuge to give better performance of mud treatment. What’s more, the cost of small centrifuge is very cheap.
2) GN 14inch bowl centrifuge with 14inch bowl size, and ration of length to diameter is over 3, to guarantee on the separation performance. The treating capacity for drilling mud can reach to 15m3/h to 25m3/h per the mud weight, viscosity etc. This model decanter centrifuge is equivalent to Swaco 518 centrifuge, Swaco 414 centrifuge, Derrick DE1000 centrifuge etc.
Many drilling contractor stop centrifuge renting service of Swaco branch or centrifuge renting service of Derrick company, they come to GN to buy their own centrifuges, and GN can offer training on centrifuge operation and maintenance. In long term, the drilling contractor can save lots of cost on mud treatment.

3) GN 18inch bowl centrifuge with 18inch bowl size and there are two options:
GNLW452 with 1800RPM bowl speed, which is specialized for barite recovery; the price is much better.
GNLW453-VFD with 0-2500RPM bowl speed, which is specialized for fast mud weight cutting, the centrifuge is controlled by VFD control panel & AC for cooling. The price is relatively higher.

4) GN 22inch bowl centrifuge and GN 30inch bowl centrifuge.
The big bowl big volume centrifuge is generally used for construction, TBM machine, Subway construction etc. In the mentioned project, large volume of mud will be engaged, and big capacity centrifuge is necessary to guarantee on the project period.

As the drilling operation going on, more and more solids will come into the mud, lead to the arising of mud weight. The change of mud weight is not good for drilling operation. Decanter centrifuge is required to remove the solids, and control the mud weight.

GN industry centrifuges

GN Solids Control is China leading brand for oil drilling mud decanter centrifuge. We have different model centrifuge for option, including:

9 inch bowl baby centrifuge, this is popular for mining/ waste water treatment.

14inch bowl high speed centrifuge, this model centrifuge is equivalent to SWACO 518 centrifuge / Derrick DE1000 centrifuge. Fixed speed centrifuge and variable speed is available per the client’s request

18inch bowl big volume centrifuge, this model centrifuge has two options: GNLW452 and GNLW453. The two option centrifuge is used differently. GNLW452 is very popular for HDD drilling, or for barite recovery; GNLW453 variable speed can be used for fast drilling

22inch bowl big capacity centrifuge, this is only GNLW553-VFD centrifuge for tunneling or other field fast drilling.

30inch bowl centrifuge is designed for industry application.

For oil drilling application mud weight control, we recommend fixed speed GNLW363CG 14inch bowl centrifuge for better option.

  • Firstly, fixed speed centrifuge is much easier for operation than variable speed centrifuge.
  • Secondly, we can offer 2700RPM bowl speed centrifuge, 3200RPM pulley with belt as backup.
  • Lastly, the fixed speed centrifuge is much better price than variable speed centrifuge.

Centrifuge feed pump, we recommend screw pump, positive displacement pump. The pump motor is controlled by the centrifuge control panel.

Telescopic skid is for option. The client can compare the price from GN, and local fabrication price.

Except for centrifuge, vertical cuttings dryer is another popular item for oil drilling waste management. The client needs it to recover the valuable oil based mud and return it back for drilling operation. We have two options: GNCD930 series cuttings dryer and GNCD730 series cuttings dryer. The client can choose the proper model per request.

Centrifuge tank works as second phase separation in mud cleaning system. This part is necessary for oil & gas drilling, for deep and complex geological structure drilling operations. Centrifuge tank generally have below options for drilling company:

14-inch-decanter-centrifuge

Option 1: rent centrifuge from solids control service / centrifuge rental company

Compared with other solids control equipment, centrifuge price is higher, as well as the higher cost on maintenance and manpower cost. As the centrifuge is not working during all drilling operations, some drilling company only rent the centrifuge when they need it.  For short terms, the rental service is helpful to drilling contractors, saving cost, time and saving works.

But from long terms, rental centrifuge will lead to higher cost, not as cost-effective as having it’s own equipment.

Option 2: buying centrifuge and train the workers to do the job

If the drilling company have many drilling rigs, and the drilling operations will last for many years. Having their own centrifuge will be much better.

GN Solids Control is China leading centrifuge manufacturer, can sell centrifuge to client or rent centrifuge to client in some area with GN office.

GN can offer middle speed centrifuge, high speed centrifuge, fixed speed centrifuge or variable speed centrifuge, motor drive centrifuge, hydraulic centrifuge etc.

If the client have enough budget, we recommend 2ea VFD centrifuge for each rigsite.  The VFD centrifuge can work flexible at any bowl speed, conveyor speed or differential speed, to achieve the best performance.

If the client budget in tight, we recommend 1ea VFD centrifuge & 1ea fixed speed centrifuge. The VFD centrifuge can work as flexible role and the fixed speed centrifuge can lower down the total cost.

Even the fixed speed centrifuge can change speed, by replacing pulley with belt, just taking more time and more manpower than VFD centrifuge.

If you need more information about decanter centrifuge, pls contact us freely.

Many China drilling contractor or oil service company have business in Africa, they bring the high technology there, help the economy development of the local market, and improve the lift of local people.

201611-22-high-g-drying-shaker

Recently,  one China government company CNPC have get some project in Africa, and give purchase order to buy drilling waste management package from GN Solids Control.  The package including below items:

1) Mud tanks with High G drying shaker

GN High G drying shaker is very popular to treat the water based mud drilling cuttings discharged from shale shaker. The patent 4 panel shaker is replacement for Swaco Mongoose.

If for oil based mud, vertical cuttings dryer will give much better working performance. However, the purchase cost and maintenance cost of Vertical cuttings dryer will be much higher than High G drying shaker. The client can make decision based on the Mud condition, budget and the special requirement from the owner.

2) Mud tanks with decanter centrifuge & flocculent unit

The WBM drilling cuttings, after treatment of High G drying shaker, the separated liquid should be transfer to decanter centrifuge for 2nd step treatment. GN decanter centrifuge have different model for option. The most popular model is 14inch bowl centrifuge GNLW363.

This decanter centrifuge is equivalent to Derrick DE1000/ Swaco 518. And we have fixed speed type and variable speed type for option.

If ultra fine solids in liquid cannot be separated by centrifuge, flocculent unit is required to coagulate the ultra fine solids to big particles, then separated by centrifuge.

3) Auxiliary equipment, including screw conveyor, transfer pumps, feeding pumps, is included for the package.

Except above part, GN can offer different model shaker screens to replace the expensive screens from original seller. The screens including:

  • GN replacement screen for Derrick FLC500 shaker, Derrick FLC2000 shaker;
