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:

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.

GN Solids Control has been working for oil & gas drilling field for about 10 years. In past years, we accumulate rich experience in mud system manufacturing, sales, operation, and maintenance. Recently, we have inquiry from Africa about 1000bbl mud system for oil drilling rig, and we give below proposal:

1) shale shaker tank

The first tank, shaker tank is equipped with 2 sets shale shaker, 1 set mud cleaner, agitators, centrifugal pumps etc.

Mud tank: 1 set, tank size 11000 X 2100 X 2150mm. The mud tank is oilfield skid mounted tank, the most popular tank type for oil drilling.

Shale shaker: we recommend GNZS594 shale shaker for better working performance, longer shaker deck and composite material screen with long lifetime.  GN composite material screen is replacement for Swaco Mongoose

Mud cleaner: we recommend mud cleaner with 2ea desander cyclones and 12ea desilter cyclones. The deck shaker is same as GNZS594 shaker, thus same type shaker screen is required, no need backup different type screens.

Centrifugal pump is equipped to feeding the mud cleaner cyclones.

The third compartment in mud tank is clean mud after treatment; mud agitator is equipped to suspending the mud.

2) Decanter centrifuge tank

The second tank, centrifuge tank is equipped with 1ea middle speed centrifuge, jet mud hopper and mixing pump.

The centrifuge GNLW452 middle speed centrifuge is used to remove the barite in the mud or other big solids particles.

The mud hopper and mixing pump is used to mixing chemicals into the drilling mud, to adjust the mud weight and mud viscosity.

Mud tank: 1 set, tank size 11000 X 2100 X 2150mm. The mud tank is oilfield skid mounted tank, the most popular tank type for oil drilling.

3) Mud storage tanks

There are another two mud tanks for mud storage, same tank size to shaker tank. The tank is equipped with necessary mud agitators, mud guns and necessary pipelines and other spares.

If you need any solids control equipment or mud system, pls contact GN 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.

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 2^nd 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
• GN replacement screen for NOV brandt king cobra shaker /VSM 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:

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.

GN mud cleaner have the same prepare module. We also have good stock for desander cones and desilter cones.

2) GN decanter centrifuge in stock

Decanter centrifuge is the most expensive item in solids control equipment line. Many overseas client rent centrifuge from centrifuge Rental Company, one time price better and very fast delivery. However, GN stock centrifuge may contribute to the purchase from clients. As for price, the cost of one set centrifuge may equal to about 3 times rental cost, it is better clients buy their own centrifuge for long term application, at least 3-5 years. As for delivery, GN stock centrifuge can give very fast delivery.

3) GN vertical cuttings dryer in stock

As the much lower oil price, the drilling waste management market should be pretty cold for long time. Anyway, we will give good service when have requirement from clients.

Russia oil drilling market prefers to buy more and more solids control equipment from China as the strained relationship between Russia and US. Since 2014, The sales amount to Russia have a big percentage for our exporting business.

1)Mud Cleaner:

GN Mud cleaner is combination of shale shaker, desander cones and desilter cones. Three units in one make the footprint much smaller, save lots of space for the surface of mud tank system.

GN have different type shale shaker, with 2 panel, 3 panel or 4 panel. Thus, the mud cleaner is also different which can be 2 panel, 3 panel or 4 panel deck shaker.

The mud cleaner treating capacity also decided by the desander cones qty or  desilter cones qty, which can be 200gpm, 500gpm, 800gpm,1000gpm or  1500gpm. We can control the treating capacity by the quantity of desander or desilter.

2) Decanter centrifuge

GN Decanter centrifuge have different options. For oil drilling, the most popular centrifuge model is GNLW363 and GNLW452. GNLW363 is high speed centrifuge with 14inch bowl size and can be used with fixed speed control panel or variable speed control panel; GNLW452 is middle speed centrifuge which is specialized for barite recovery or big solids separation.

Except for above two model centrifuge, we also have another model centrifuge in different bowl size. Pls check more from GN website:  GN Decanter centrifuge

As the crude oil price is lower, many drilling company stop drilling operation and are busy with oily sludge. They want to treat the oily sludge, recover valuable oil, and reduce the impact on the environment. Government in every country also has related regulations on environmental protection.

After about half year communication with different oily sludge client, we promote oily sludge treatment system with shaker, centrifuge, chemical dosing system, and O/W separator. The system includes 4 parts.

Part 1: Mixing tank with shaker and agitators

The shaker on the tank is long deck shale shaker with hot line inlet water/steam, which can help to improve the separation performance of shaker screen. We also advise coarse mesh screen for longer working life, and to avoid sludge stick on the screen.

After separation of shaker, the liquid go down to the mixing tank, the agitator will suspending it. Meanwhile, the chemical will coming from chemical dosing system. Here, the oily sludge will be diluted and have better separation.

Part 2: Chemical dosing system

The chemical dosing system including PAM three tank dosing system, acid tank etc.

Part 3: Centrifuge on telescopic skid

After the mixing tank, the oily sludge will be transfer to centrifuge system. High speed centrifuge can separate the fine solids, discharge down to skips, and the clean liquid go to slant plate clarifier.

We recommend most popular centrifuge model GNLW363 series. The 14inch centrifuge is equivalent to Swaco 518 centrifuge or Derrick DE1000 centrifuges. We have lots of client shift from Swaco/Derrick to GN for centrifuge requirements.

Big bowl big capacity centrifuge is also available, GNLW553 centrifuge is 22inch centrifuge with big volume.

Part 4: slant plate clarifier and O/W separator

Via slant plate clarifier, the solids will be removed. Then, the liquid go to O/W separator, here the liquid will be separated into oil and water. Oil pump to oil tank; water pump to water tank.
