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.

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 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
  • 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:

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.

OBM waste management is necessary for drilling rigsite environmental protection. It may revolved in vertical cuttings dryer, decanter centrifuge, thermal desorption unit etc. We have provided over 20 sets OBM waste management system to overseas market and domestic market. The working performance of GN OBM waste management system win high praise from clients and they give repeat order to GN Solids Control.

In some countries, there is policy for no pit drilling. Even Water based mud, the drilling company cannot dispose it directly into mud pit. Our company design WBM waste management total solution for no pit drilling company. The equipment may but not limited to below items:

GN high G shaker for water based mud drilling cuttings treatment, have two models for choose. One model is only High G shaker without beneath tank.  In this case, the operator should design one cement pit or separate mud tank to hold the liquid part after High G shaker.  The other model is High G shaker with beneath tank for fast use.

After High G shaker, high speed and variable speed centrifuge will be used for fine solids separation. GN Solids Control design decanter centrifuge with height adjustable skid for convenient use.

Recently, we have one drilling waste management service customer who buys 1 sets high G shaker with beneath tank and 1 set variable speed centrifuge with high skid. The detailed technical specifications as below:

1) High G shaker with beneath tank: The shaker is GNZS594HGE-LD shaker with 4 panel shaker screen (composite material frame screen and steel frame screen both available). The drying time should be longer than 2 panel or 3 panel shaker, and the performance should be much better. The shaker with hopper type feeding, total height is much lower than weir type feeding or box type feeding, match better with drilling cuttings treatment job.

On oil drilling rig site, Hi-G dryer shaker and double deck shaker is widely used for drilling cuttings treatment and recycling. They are both linear motion shale shaker. Some customer do not know the difference of Double deck shale shaker and High-G dryer shaker. As world top solids control and waste management equipment manufacturer, GN Solids can tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Hi-G Dryer Shaker ( recommended model GNZS594, linear motion)

Compared with traditional shale shaker, this model with a Higher G force, can get better vibration screen separation. This model with 4 panel Mongoose shaker screen, can get bigger treating capacity. And the shaker screen is interchangeable with Swaco Mongoose screen, you can get the shaker screen from local Swaco distributor easily.

As it is single deck, relative easy to change shaker screen compared with double deck shale shaker.
