GNZS703 shale shaker produced by GN solids control has been widely used in oil & gas drilling. GNZS853 shale shaker is normally used for drilling cuttings treatment.
Below is the photo taken in South America oilfield drilling site. They use GN shale shaker to separate the large solids from the drilling fluids and get clean mud for reuse. Also they user GN shale shaker as a underflow shaker to help the performance of desander cone & desilter cone.

To know how to operate GN shale shaker is much more important, also the maintenance. Only if you operate and maintain it according to the manual, you will use it same with Derrick, SWACO shale shakers.
1 Angle adjustment
The angle can be adjusted both under running and off condition.When delivered ,the deck is horizontal(0°) 。While operating with the same shaker screen, according to the worksite mud property, and feeding capacity ,by adjusting the deck angle in order to improve the treatment result .When the drilling mud run off, enlarge the deck angle to solve the problem. Angle adjustment range -1°~+5°，rated angle 0°~3°。
2 Pool configuration
A better pool configuration can maximize the screen area and such achieve better result. It is hard to set the deck angle at one time ,it needs the operation personnel adjusting several times according to the flow of the mud .The best pool configuration is when the mud covers the first and second shaker screen.

Drill cuttings are separated by shale shaker, decander, desiler, decanter centrifuge, and collected by screw conveyor or vacuum unit , for further separation of vertical cutting dryer & decanter centrifuge.
drill cuttings separation
In an ideal situation, all drill solids are removed from a drilling fluid by solids control equipment on a drilling operation. The two primary sources of solids are chemical additives and formation drill cuttings. Drill cuttings are contaminants that degrade the performance of the drilling fluid. If the drill cuttings are not separated, they will be ground into smaller and smaller particles that become more difficult to remove from the drilling fluid.
Most formation solids can be removed by mechanical means at the surface. Small particles are more difficult to remove and have a greater effect on drilling fluid properties than large particles. The particle size of drilled solids incorporated into drilling fluid can range from 1 to 250 microns (1 micron equals 1/25, 400 of an inch of 1/1000 of a millimetre).

Simply speaking, mud cleaner is shale shaker, desander, desilter assy, it is also called 3 in 1. GNZJ703 & GNZJ853 is the best choice for large treating capacity, large screen area mud cleaner, most of our clients use GN made mud cleaner before GN decanter centrifuge, this action can improve the performance of GN decanting centrifuge.
Mud cleaner maintenance including
(1)Clean dust on shell regularly
(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker
(3)Inspect the cable, whether there is wear, hold down, crushing, etc.
(4)the vibration motor should be under good lubrication during operation:
Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃
(1)Before every shut off, the shaker should run without any load for 5-10 minutes, at the same time, use clean water to flush screen clean
(2)Every time finish operation, the shaker frame and screen should be flushed by water. Pls replace new screen or repair the damaged screen once it is found damage, otherwise large cutting may dropped into the clean mud and influence the following process.

Drilling engineering is a subset of petroleum engineering. Drilling engineers design and implement procedures to drill wells as safely and economically as possible.
Exploration and petroleum engineering are the oil and gas industry’s two main sections. Petroleum engineering is a field of engineering related to the production of crude oil or natural gas.
Drilling engineers are in charge of the process of planning and drilling the wells. Their responsibilities include:
- Designing well programs to prevent blowouts
- Designing casing strings and cementing plans, directional drilling plans, drilling fluids programs, and drill string and drill bit programs.
- Specifying equipment, material and ratings and grades to be used in the drilling process.
- Providing technical support and audit during the drilling process.
- Performing cost estimates and analysis.
- Developing contracts with vendors.
Solids Control is one of the most important phases of the drilling process. The primary reason for using mechanical solids control equipment is to remove detrimental drilled solids from the mud system. Mechanical separation of drilled solids is achieved via screen separation(shale shaker, mud cleaner, desander, desilter) or accelerated g-force（decanter centrifuge）. Continue reading »
Mud cleaner is a combination of shale shaker, desander, desilter for oilfield drilling mud system, NOV Brandt also called it mud conditioner. There are many suppliers for mud cleaners, Derrick, MI-SWACO, Brandt, GN Solids Control, here we will make a comparison of the 4 model of mud cleaners. Take 1000gpm unit for example:
1 Derrick Mud Cleaner Features:
A round desilter manifold and/or a desander manifold is mounted in a cone discharge collection pan installed over the vibrating screen.Underflow from the hydrocyclones is received by the collection pan, which may feed directly to discharge or onto the vibrating screens for additional processing.
Derrick’s standard desander cone and desilter cone is 10” & 4”
2 MI-SWACO Mud Cleaner features:
Low profile through
Vertical installation method of desilter cone
MI-SWACO’s standard desander cone and desilter cone is 12” and 4”
Patented pin-and-hole screen securing system
Brandt’s standard desander cone and desilter cone is 10” or 12” and 4”
Small footprint, compact design; desilter cone is installed vertical but inclined, GN standard desander cone and desilter cone is also 10 inch and 4 inch, which is same with Derrick’s.
But compared with GN mud cleaner, the mud cleaner produced by Derrick, MI-SWACO, Brandt are Continue reading »

Decanter centrifuge can be used as 2 functions: one is to used in drilling mud solids control system, to recycle drilling fluids and get barite. The other one is to used in drilling waste management system, to treat the drilling waste and recycle drilling fluids. GN decanter centrifuges are working in many sites in Brazil for such purpose.
Other related equipments with centrifuge:
decanter centrifuge rental in Brazil
In drilling fluids solids control system, centrifuge is used after desander and desilter, when they need to separate fine solids.
In drilling waste management system, centrifuge is used after cutting dryer, when they need to recycle the clean drilling fluids and drain off the cuttings. Sometimes it is used after hi-G shaker, it depends on the drilling mud type.
GN can provide both equipments related to the centrifuge.
People rent centrifuge because of the high cost of US centrifuge, also because of the maintenance cost, sometimes clients only want to use the centrifuge for a short while, so centrifuge rental is economic for them. But most of the clients rent centrifuge because they have Continue reading »
