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;
  • GN replacement screen for Swaco Mongoose shaker

Even the oil drilling market is very down, we still can receive some purchase orders from old clients. Recently, we finish production for waste management system, and is exporting to Uganda, Africa now. China Oilfield Services Limited (COSL) bought the equipment and doing drilling operations there.  The project including below items:

201611-22-high-g-drying-shaker

1) High G dryer with collection tank beneath.

The High G dryer is GN 4 panel shale shaker with up to 8G vibration motor, and 4pcs composite material shaker screen. The high G force and longer deck can make the solids discharge much dryer, which is easier for transportation.  The clean mud will drop down to the beneath catch tank.

2) High speed decanter centrifuge with mud catch tank

The decanter centrifuge is GN 14inch high speed centrifuge, which is the most popular model for oil & gas drilling. The 14inch centrifuge is equivalent to Swaco 518 centrifuge or Derrick DE1000 centrifuge. Many client used Swaco/Derrick centrifuge before, and shift to GN after knowing GN strength and high quality of GN centrifuge.

The high speed centrifuge can be set to 3200RPM, which can separate 2-5microns fine solids. The clean drilling mud drop down to the catch tank below. Then, the screw pump will transfer the clean mud back to drilling active tanks for reuse.

Above equipment system is more proper for water based mud treatment. For oil based mud cuttings treatment, Vertical cuttings dryer will give much better performance. GN vertical cuttings dryer have been put into market for over 3 years. The separation  point is mainly depends on the screen basket, 0.25mm/0.35mm/0.5mm opening for options.

As China & USA leading brand for solids control / drilling waste management, GN Solids Control have various product to meet the different needs, including vertical cuttings dryer, high G dryer, decanter centrifuge, solidification unit, thermal desorption unit etc.

GN decanter centrifuge with tungsten alloy tiles screw conveyor can have a much longer lifetime with good working performance. The Ex-proof control panel with positive pressurized air can keep inside lower temperature, and keep it clean without dust and keep it dry; all the features make the centrifuge & VFD control panel good performance and less maintenance.

One client from Africa, they bought 2 batches decanter centrifuge from us in past 3 years. The client is local land rig drilling contractor with 7 land rigs. They use the centrifuge for solids control, each rig need two sets centrifuge, the client have their own centrifuge from us, and they also rent some centrifuges locally.

14-inch-decanter-centrifuge-2

Recently, we have got news from the clients that they are doing some maintenance for the VFD control panel and are faced with some challenges.

  • Challenge 1: the centrifuge cannot separate anything
  • Challenge 2: the PLC control panel don’t display correct rotation speed value as reset
  • Challenge 3: The centrifuge motor don’t rotate in correct direction

After several times discussion by email and by phones, we are clear that all the disorder is because of the electrical components in the VFD control panel which have been replaced by client is not working in correct mode. After we give instruction on how to adjust the Omren module components in the Control box, the centrifuge can work in correct mode as before.

The centrifuge motor rotation direction is also very important to the centrifuge performance. If the rotation direction is not correct, it will not remove solids and will not work normally. We have direction arrow in red stick on the motor end, it is much necessary for client to check the rotation direction before test the centrifuge.

Except for centrifuge, GN Solids Control also provide all line of solids control equipment, like shale shaker, mud cleaner, mud agitator, mud gun, shear pump, screw pump, slurry pump, mud tanks etc.

For drilling waste management, the products line including: vertical cuttings dryer, thermal desorption unit, fixation unit, screw conveyor etc.

GN Solids Control solids liquid separation decanter centrifuge have been working for oil drilling many years. The stable working performance and reliable life time win good reputation for GN Solids Control. And now we just published three phase  centrifuge for solids, water and oil three phase separation.

3-Phase-Decanter-Centrifuge

14-inch-decanter-centrifuge

Except for decanter centrifuge and three phase centrifuge, GN main market is still in drilling waste management and solids control equipment.

GN drilling waste management equipment including: vertical cuttings dryer, waste centrifuge, solidification unit, fixation unit, thermal desorption unit, etc. Drilling Waste management equipment is used to treat the solids mixture discharged from shaker, recover valuable drilling fluids for reuse and reduce the waste need to be treated in following stages.

For water based mud, client normal choose High G drying shaker, decanter centrifuge and solidification unit. After treatment of solidification unit, the solids can be buried in cement ponds as final step. For oil based mud, client need to use vertical cuttings dryer, decanter centrifuge, thermal desorption unit. Thermal desorption unit can get cuttings solids with oil below 0.3%, this standard can meet the requirement of most country’s government protection policy. Compared with water based mud, OBM cuttings treatment cost is much higher both in equipment expense and operation cost.

GN Solids Control equipment including: shale shaker, mud cleaner, shaker screens, desander, desilter, decanter centrifuges, mud agitator, centrifugal pump, screw pump, mud tanks etc. GN Solids Control mud system can form a close loop mud circulation with drilling rig and mud pumps. After the mud ready for drilling, the mud pump will suck from the mud system and feeding for drilling rig. The mud from drilling rig flowline will go back to mud tank system for cleaning, adjusting and go back to mud pump. The mud tank system generally include four stage mud treatment and will remove particles in different size by different stage, shale shaker stage, desander stage, desilter stage and decanter centrifuge stage. Two phase separation centrifuge is mostly used in solids control system, very few clients choose three phase centrifuge.
