The persons who know solids control equipment may know well on the shale shaker and mud cleaner unit. These 2 machines are very common in solids control system that do solids separation job from the first to forth stage. The shale shaker is located at the very beginning of the mud recycling system for primary solids control; the coarse cuttings could be removed by the shale shaker. While after treated by the shale shaker, the drilling fluids would be transferred to the mud cleaner for further treatment.
For the purpose of easy maintenance, in the same solids control system, the mud cleaner is equipped with under drying shaker that is same model as the primary shale shaker. Mud cleaner is just a machine on which the cyclone frame was fixed above. The mud cleaner unit is only able to be used to separate the solids via the hydrocyclone units. Why the mud cleaner unit cannot be used as a shale shaker even if it has the under drying shaker? This is really a good question. GN’s engineer equipped a logging tank to the mud cleaner unit and the mud cleaner unit becomes a shale and mud cleaner composition unit.

GN Shaker & Mud Cleaner Composition Unit

Normally, GN’s shaker unit has back type logging tank that is used to collect the drilling fluids coming out from the drilling hole. The drilling fluids accumulated in the logging box firstly and then overflow into the shaker deck, thus the shaker screen will not be damaged by the high pressure drilling fluids. This unit could be used as a shale shaker unit.
De-sanding and de-silting cyclone are installed on the mud cleaner for finer solids separation. The solid discharged out from the bottom nozzle of the cyclone also has high pressure that will shorten the screen life if directly dropped onto the screen surface. To avoid this situation, there is a hopper collection box that is used as buffer between the cyclone and screen. To make this machine compact, GN’s engineer designed to insert the buffer box into the logging box, which means the logging box is also used as second buffer box for the cyclone unit. This is the function of mud cleaner.
One thing need to be noted is this shaker and cleaner machine can only be used for one function one time: either shaker or mud cleaner. This is a cost saving unit with small footprint, for some project not very urgent, this unit could be a very ideal choice. GN ever showed this unit at Beijing CIPPE, much attention was attracted there.

De-sander is very popular equipment used in solids and liquid separation processing. It always contains cyclone unit and steel frame. With different diameter of the cone body, this cyclone unit could separate the solid particles with different sizes. GN’s de-sander is using 10 inch cyclones which could remove the solids size down to around 45 microns.
GN’s de-sander unit is used in drilling industry to separate the drilling cuttings from the drilling fluids. Traditional de-sander units don’t have the under drying shaker for maximum recovery of the drilling fluids liquid, thus a large amount of valuable drilling fluids was lost. However, this type de-sander and even the de- silter unit are very simple structure and cost effective.

To make the discharged solids much dryer, GN prefer to suggest choosing the de-sander unit with a under drying shaker which could recycle much more drilling fluids. This could reduce the waste discharges to environment and the cost on drilling fluids materials. GN has a de-sander model with under drying shaker of 2 layers screens panel. This unit is functioning as both primary shale shaker and de-sander unit. The drilling fluids gets into this de-sander unit via the mud distributor pipe and then flow on the bottom layer screen firstly for primary solids control. Liquid gets through the screen mesh and falls down to the under located mud tank. Large size particles will be discharged out of the shaker. And then the liquid will be transferred by a centrifugal pump unit to the de-sander cyclone unit for fine solids separation. The mixture of liquid and solids discharged from the cyclone will come to the upper layers screen for drying processing. Here, to prevent the damage of screen mesh resulted by the strong impact force of solids discharged out from the cyclone unit, GN designs small buffer box to cover the outlet of the cyclone. This buffer box is small enough to make the unit more compact.
GN’s double-layer screen panel shale shaker can also be used as only primary shaker for much fine solids separation. Besides de-sander unit, de-silter unit can also use this type shaker as drying shaker.

Shaker screen users may know that there are flat type screen and pyramid type screen used very often on the shale shakers to separate the cuttings from the used drilling fluids.
The flat type shaker screen are very common in screen application, with 3 layers wire mesh stacked and closely connected with the steel back frame. Always there are hook strip type and steel tube frame type screen. Different from the flat type screen with a flat shape screen panel, the pyramid type screen is designed three dimensions screen panel like a wave. This pyramid screen design firstly issued by the world No. 1 solids control equipment manufacturer of Derrick Equipment. And they do have patent for this design.

GN replacment pyramid creen

Comparing with flat type screen, the pyramid type screen has below several advantages.
1. Make a larger effective screen area. Due to the wave type with top and troughs, in fact, the screen panel has a larger screen area than the flat type if the screen panels have same width and length. The pyramid screen let more drilling fluids distribute on the screen and more fluids will with solids less than the mesh will go through the screen.
2. Under the G force and gravity, the solids will accumulate at the troughs of the screen. Comparing with the flat type screen with solids distribute uniformly on the whole screen panel which will impede the go though the screen, the pyramid screen has the wave top and slopes at both sides will let drilling fluids come through.
3. The pyramid screen will make the fluids distribute as a much thinner layers which also helps to increase the flow rate and make the solids much dryer. And it can also separate solids around 3 meshes finer than the flat type screens.
These advantages pyramid screen will especially appear more clear when fed with larger volume drilling fluids that can submerge the screen panel. Thus the full screen effective area will be fully used.

Shaker Screen is one of the very often uses wear parts for drilling process. When starting the drilling process, the shaker screen is installed on the shale shaker unit to separate the solid particles in drilling fluids. The fine holes on screen panel could block the solids larger than the hole size, while the liquid could go through easily. On oil field, most of the shale shaker unit is using 3 or 4 panel screens. According to different condition of the drilling fluids and usage, the driller need make some inventory of the spare shaker screen.

Double deck shale shaker and High G shale shaker is widely used for oil and gas drilling rigs site.They can be used for both mud solids control or drilling cuttings waste management.

They are both linear motion shale shaker. Many customer do not know the difference of Double deck shale shaker and High G shale shaker. Below is the explanation from world top solids control and waste management equipment manufacturer – GN Solids Control. Let GN tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Double deck shale shaker, linear motion: GNZS703D

double deck shale shaker linear motion

double deck shale shaker linear motion

GNZS703D is the typical double deck shale shaker. It utilized 2 each shaker screen for top deck and 3 each shaker screens for bottom deck.

Advantages of GNZS703D double deck shale shaker

1). For the same API size and the same area bottom shaker screen. double deck shale shaker can treat a bigger capacity. The wide-meshed shaker screen on top deck can separate most big size solids before the mud enter into the bottom deck. It greatly reduce the load of bottom shaker screen.

2). For the same API size and the same screen area shaker screen. double deck shale shaker can separate the drilling mud or drilling cuttings more dryer. As there are 2 times shale shaker separation.

Disadvantage of double deck shale shaker

The double deck shale shaker have advantages of bigger advantage and dryer separation result, but it has some difficult to change shaker screen. And the cost of replacement shaker screen also higher, as there are 5 each screen for a shale shaker.

High G shale shaker, linear motion: GNZS594

linear motion high G shale shaker

linear motion high G shale shaker

GNZS594 is a high G shale shaker model, with linear motion. It uses 4 panel shaker screen. And the shaker screen interchangeable with Swaco Mongoose shale shaker, composite material. It is single deck, relative easy to change shaker screen compared with double deck shale shaker.

Conclusion

So the user can choose shaker type per your drilling rig conditions and per your applications (for solids control or for waste management). If you have a higher solids content, or want bigger capacity, and take more time for screen changing is not problem, you can choose double deck shale shaker. If you prefer fast screen changing, high G shale shaker single deck is better.

Functions of solids control equipment- shale shaker

Solids Control shale shaker is the first stage separation equipment for oilfield drilling mud cleaning system. It utilizes vibrating motor to generate vibrating strength. The vibrating strength drive the drilling mud going through the shale shaker. When the drilling mud go through the shaker screen, clean mud will filter into mud tank. Not allowable bigger solids will pass the screen surface and been discharged.

Types of solids control equipment – shale shaker

Per different motion design. There are mainly 2 types of shale shaker:

1) Linear motion shale shaker. It is the most common shaker model for oil and gas drilling solids control system

2) Balanced Elliptical motion shale shaker. It is not recommended for oil and gas drilling, as the flow capacity is big. The BEM shaker, while mud flow not equal, the motion of the shaker will be changed. And performance not good. Mostly, professional users prefer linear motion for a wide use.

Separation size of solids control equipment – shale shaker

The separation size of the shale shaker equipment depends on shaker screen size. We call it API size or mesh size. The API defers from API 20 to API 325 per API RP13 standard.

Through changing different API size shaker screen, the solids control shale shaker can separate solids size min. above 40 microns (at API 325 shaker screen)

If you do not need to separate so fine solids, you can choose more fine shaker screen, Like 800 microns @ API 20.

The common screen API size for solids control shale shaker is API60, API80, API100, API140,API160. Customer can choose the suitable size per drilling mud condition.
