The separation size of drilling fluids shale shaker

Drilling fluids shale shaker, the new development of OGEM Solids Control, is an ideal primary solids control equipment for drilling mud circulating system and is characteristic by high performance and easy maintenance.Oil field drilling mud shale shaker mainly consists of explosion-proof vibrating motor, screens, explosion-proof controller, feeder and mechanical lifting system.

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 since the flow capacity is big. If the mud flow is not equal, the motion of shaker will be changed. And performance will not be good. Mostly, professional users prefer linear motion for wide application.

Separation Size of Solids Control Equipment – Shale Shaker
The separation size of shale shaker 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 shale shaker can separate solids size min. above 40μm (at API 325 shaker screen).
If you do not need to separate so fine solids, you can choose more fine shaker screen, like 800μm.
The common screen API size for shale shaker is API60, API80, API100, API140, API160. Customer can choose the suitable size per drilling mud condition.

Drilling fluid shale shaker

Do you know the double shale shaker ?

Shale shaker is the first stage solids control equipment in drilling fluids processing system,also known as key solids control equipment in drilling mud solids control system. The drilling fluids shale shaker can remove cuttings above 75μm brought from the drilling well to leave the liquid with smaller particles into the drilling fluid circulation mud tanks, which will flow into next stage drilling fluids solids control equipment to be treated.

Double shale shakers
Oilfield shale shakers like derrick shaker and brandt shaker are ordinarily consist of skid, vibration isolation fellow member, screen, screen basket, back again tank ( or referred to as mud feeder), vibration engine, and many others. No issue it is linear movement shale shaker, or ellipse shaker. ?The drilling fluids flows straight into the back tank via the flow line right after the mud arrives out of the surface area of the properly. The solids that precipitates in the back again tank would be discharged via the bottom hole, and drilling fluids would flow onto the screen surface area. The solids that are larger than the meshes would be divided and threw out of the shale shaker via other finish of screen. And the fluids with scaled-down component would go via the meshes and key in the mud tank for even more separation.

Shale shaker framework

The screen of shale shaker can be pieces of panels, or a single integrated panel. The angle of the screen can be horizontal, or with a specific angle, or adjustable inside of an angle variety, like -1° ~ +5° or -3° ~ +6°. The screen can be a single layer, or double layers. The engineer should select the correct kind of shale shakers in accordance to the geological and drilling fluids needs. When the drilling fluids amount is big, double or triple shale shakers could be operated, this kind of the purification capability of the linear motion shale shaker would be far better enhanced.

OGEM Solids Control can manufacture types of drilling fluid solids control systems according to the requirements of different drilling conditions. OGEM Solids Control is well-know as a professional manufacturer and decanter centrifuge supplier of oil drilling solids control equipment in China.

Do you know of origin of Shale Shaker


In the 1930s, the early system of solids control was used. It started with the shale shaker. As the primary stage,drilling shale shaker  removes solids from drilling fluid with gravity and vibrating working principle. Shale shakers are set with durable steel screens to filter unwanted materials from drilling fluids.

The modern solids control process has had many machines, systems and other parts. The most essential solids control machines include shale shaker, mud desander, oilfield desilter and decanter centrifuge. Due to solids control measure, bore drilling has become far more economical as the drilling solution is reused.

Drilling fluid shale shaker

OGEM Solids Control highly promotes linear motion shale shaker, which is regarded to be effective to deal with heavy and high-volume solids from drilling mud. Shale shaker is the solids control equipment with feeders, which can be weir feeders or box feeders. OGEM Solids Control shale shaker feeders come in weir type, box type and bucket type. The weir type and box type feeders are mainly used to buffer the flow rate of drilling fluids, and evenly distribute the fluids onto the screens to reduce the impact of drilling fluids, as well as extend the service life of screen so as to improve the treatment effect.

In order to ensure the process, drilling mud shale shaker can generate powerful G-force, maximum to 7.4G. Such shale shaker has effective vibrating motion and could quickly remove the dense solids from screens and particles from wells.


Shale Shaker for Petroleum Drilling Solids Control

Shale shaker is utilized in many different industries, such as coal cleaning plant, mining,

petroleum drilling, and natural gas exploitation, etc. and the shakers that are currently

used in petroleum drilling were initially introduced from the coal cleaning industry. It can

remove the solids that is over 75μm diameter. As solids over this diameter is much

harmful on the drilling fluids property. They must be removed from the drilling mud at the

first stage of solids control system. And shale shaker with API 200 mesh (75μm) is

designed and manufacutured basing on this principle.

Drilling fluid shale shaker

I.  The Importance of Shale Shaker.

Shale shaker plays an important role in solids control system, and it is the most important

and earliest equipment that are used to separate the solids in the drilling fluids. It is the first

purification stage after drilling fluids return to the surface of the well, and has very strong

effect on the drilling fluids property, specially on the cost of drilling. If the shaker screen

that is to be used on the shaker is not correct, or worn, or even worse, the drilling fluids

enter into the mud tank directly, but not through the screen, the equipments at subsequent

purification stages may not work normally. This would definitely effect the drilling speed

and the cost. So the drilling team must place and utilize the shale shaker in a right way

according to the drilling mud property.

II. The Formation of Shale Shaker.

Shale shaker is consist of weled base, screen basket, screen, vibration motor, angle

adjust device, feeder, explosion-proof switch, etc. Sometime in order to treat relative big

volume drilling fluids, double or triple shale shakers are used, which two or three shakers

are combined to work together. Drilling fluids first flow into the feeder, and then flow onto

the screen. While the angle of screen basket can be adjusted -1° ~ +5° through the angle

adjust device while drilling, no need to stop the drilling process. and the vibration motor,

through driving its two pcs eccentric blocks retating, generates the vibration force on

screen basket. So according to the diference of solids vibration tracks, shale shakers are

divided into elliptical shaker, linear-motion shaker, and circular shaker.

III. The Nomenclature of Screen.

Before the new ISO standard was issued, shaker screens were named according to the

screen mesh sizes.  The screen mesh sizes means the number of mesh per one inch

length of the screen edge. At that time, most meshs are square, so this is advisable. After

the new ISO standard nomenclature was issued, the British unit was not available any

more. And also new complecated shale shakers were invented, these required the change

of the shale shaker nomentacure. Normally API 20 meshes ~ 50 meshes is considered to

be the cribble screen, and API 150 meshes ~325 meshes to be the fine screen.

Drilling mud cleaner for solids control

History of mud cleaner

Although US Patent No.3,766,997 covering Mud Cleaner was issued on October 23, 1973 granted to J.K. Heilhecker and L.H. Robinson and assigned to Exxon Production Research Company, it was found invalid and efforts for re-issue was unsuccessful because of the existence of prior art filed at the British Patent Office by a German Inventor in the late 1800s.

Nowadays, mud cleaner used in oilfield means the equipment processing drilling mud. It is combined with desander cone and desilter cone as well as bottom shaker. It is called 2nd and 3rd phase solids control equipments.


Description of mud cleaner

A mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where in particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters.

Process flow of mud cleaner

The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite size particles to pass through the screen returning and recovering then the clean mud.

Purpose of mud cleaner

The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids larger than 74-105 micrometres can be removed by the mud cleaner before the viscosity builds up.


Mud Cleaner is the second class and the third class solids control equipment which is the newest type to treat the drilling fluid. OGEM drilling mud cleaners are combined from Desander, Desilter and an Underflow Screen, at the same time

Mud cleaner has the higher cleaning function compared with separated desander and desilter. In addition to the reasonable design process, it equals another shale shaker. OGEM mud cleaner structure is compact, it occupies small space and the function is powerful. Mud cleaner is the ideal device of the second class and the third class solid control to treat the drilling mud.


Drilling mud Cleaners for drilling fluids solids control:

 Drilling mud cleaner is also called Desander and Desilter assembly, which is the combination of desander, desilter and an underflow screen. Namely, mud cleaners consist of a two-stage separation process using a combination of hydrocyclones mounted over a shale shaker to operate as a single unit.

Designed to handle the entire circulating volume, Drilling cuttings cleaners are effective on both weighted and unweighted drilling-fluid systems in removing and drying solids while retaining the expensive liquid. The hydrocyclones (desanders and desilters) make the primary separation with underflow directed onto the shaker’s vibrating screen. Used correctly, the drilling mud cleaner lower both drilling-fluid and disposal costs.
In oilfield solids control, drilling mud cleaners are very efficient for oil gas well drilling mud purification system. Mud Cleaners are one of the important equipments for solids liquid separation system.


We are an exporter of drilling mud cleaner for companies all around the world. Our  company is Quality Management System ISO 9001-2008 certified. OGEM Solids Control operates waste mud management international sales, service, manufacturing, distribution service.

Buy drilling mud cleaners from China manufacturer, good quality, best price, OGEM is your best choice of drilling mud cleaner.
