An oil field shale shaker is a vital piece of equipment used in the oil and gas industry during the drilling process. It is a vibrating shaker screen that helps separate drilling cuttings, solids, and other debris from drilling fluids or mud. The shale shaker plays a crucial role in maintaining the drilling fluid’s properties and removing unwanted solids to ensure efficient and safe drilling operations.

The efficiency of an oil field shale shaker depends on several factors, including the shaker screen mesh size, vibration intensity, and the characteristics of the drilling fluid. Proper selection and maintenance of the shaker screens are crucial for achieving effective solids control and maximizing drilling fluid performance.

Overall, the shale shaker is an essential component of the drilling process in the oil and gas industry, helping to remove solids and maintain the quality of drilling fluids, which is vital for efficient and safe drilling operations.

Oil field shaker screens must be stocked indoors for several reasons. Firstly, storing them indoors protects them from exposure to harsh weather conditions such as rain, extreme temperatures, and direct sunlight, which can deteriorate the screens and reduce their effectiveness.

Secondly, indoor storage helps prevent contamination of the screens. Oil field operations involve various types of drilling fluids and chemicals, which can potentially damage the screens if they come into contact with them. Storing the screens indoors minimizes the risk of contamination and ensures their integrity.

Thirdly, indoor storage provides a controlled environment that helps maintain the quality and performance of the screens. Factors such as humidity, dust, and airborne particles can negatively impact the screens’ efficiency and lifespan. By keeping them indoors, these factors can be better regulated, prolonging the screens’ usability and effectiveness.

Overall, storing oil field shaker screens indoors is essential to preserve their quality, protect them from damage, and ensure optimal performance during oil field operations.

Shale shaker screen is the most important and necessary wearing spare parts for oilfield shale shaker and mud cleaner. The function of a shale shaker screen is to remove the particles bigger than the screen opening, and recover the usable drilling fluids which will go through the screen openings and get back to the drilling mud recycling system.

There are many brands shale shaker and mud cleaner, and every brand has his own design and own sizes shale shaker screens. In order to control the mud weight accurately, how do the mud engineers choose the right screens openings from different shale shaker and shale shaker screen suppliers?

In order to solve the problem, a general standard is necessary for design shale shaker screens. API RP 13C is an international popular standard to define the shale shaker screen specifications. A authorized lab will test a shaker screen by using a specific test procedure (as described in API RP 13C), the lab test will define a series of specifications of the screen, like D100 cut point, screen conductance, non-blanked area. After these specifications are confirmed, the API Screen Number is determined. It ensures that, all Shale shaker screens confirmed to API RP13C standard, if the API No. is the same, the screen cut point will be the same. Same model screens from different screen suppliers if with the same API NO., the screens are interchangeable.

Below definitions are some important parameters of shale shaker screens to help you know more about API screens:
API screen NO.: After testing a screen by using a specific test procedure (as described in API RP 13C), the API screen no. is determined.
Mesh: it relates to a piece of screen wirecloth, is a measure of the number of holes in a linear inch (such as 100 mesh) or in a linear inch in each direction (such as 100 x 60 mesh).
D100 Cut Point: The D100 cut point of a screen is the largest particle size which will pass through the screen opening. D100 means 100% percent separation.
Screen Conductance: It measured in kilodarcies per millimeter (kD/mm), defines a Newtonian fluid’s ability to flow through a unit area of screen in a laminar flow regime under prescribed test conditions. All other factors being equal the screen with the higher conductance number should process more flow.
Non-Blanked Area: The non-blanked area of a screen describes the net unblocked area in square feet (ft²) or square meters (m²) available to permit the passage of fluid.

GN Solids Control makes API RP13 shale shaker screens for different shaker brand. May you have any questions, welcome you contact GN Solids Control for inquire.

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.

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.
