  1. Variable Speed Decanter Centrifuge

The variable speed decanter centrifuge is controlled by VFD control cabinet. All the parameters can be changed easily in the control panel, such as rotating speed of the bowl, different speed. The feeding speed of positive displacement pump can also be changed by using the VFD control cabinet.

  1. Fix speed Decanter Centrifuge

GN fix speed decanter centrifuge is using a fluid coupling to increase the rotating speed of the bowl and screw propeller little by little. It can protect the motor from damage effectively.

No matter the variable speed decanter centrifuge or the fix speed decanter centrifuge, the mechanical parts of GN decanter centrifuge are the same. Now the third version centrifuge, such as GNLW363CG, it is using the good quality material SS 205 by centrifugal casting without any welding or bending. The drilling fluids feed into the large end of the rotating bowl can help to improve the treating capacity largely.

GN engineers also apply cutting edge technologies to upgrade the decanter centrifuges by using ceramic inserts to protect the effluent port and solid port.

GN decanter centrifuges in Houston warehouse are always available, welcome to have a look and more information about GN other products click this link ,

Points that need to consider when choosing mud system

Zero-discharge mud recycle system is loop system that use the drilling mud continually  while performing filtering for solids that contain in the mud.  The function is similar human’s blood system.  To treat the mud properly through solids control, the mud system need to consider in points below:

  • Drilling rig type and spec
  • Speed of the drilling process
  • Solids that will be filter
  • bore length
  • The gallon per minute (GPM) of the pumps
  • Volume and amount of tanks that are needed
  • How many and what size of hydrocyclone
  • The filter screen size for shale shaker and mesh number

These factors determine your mud system that is adequate enough to clean the mud and protect the components and the drill bit of the rig, pumps and mud cleaners.

Treating Capacity:  Rule of thumb, double the actual treating capacity.

The mounting of system; trailer or skid.  Trailer mount is need mount on trailer and it becomes part of the system.  Skid mount is detachable from the flat transportation method.

Shale shaker screen area: Larger the treating area, treating volume is larger. if project needs.

Mesh selection:  In reference the solids that need to be filtered.  The mesh# (API#) is number of opening per square inch.  Depend the solids size and density of the mud will determine choice of the screen.

Shale Shakers: There are three different kind of shale shakers (orbital, elliptical and linear). Orbital is a circular motion and elliptical isn’t perfectly circular — it’s an ellipse or oval. Linear has vibration that is induced by a pair of eccentric (or eccentrically weighted) shafts turning in opposite directions. This type of arrangement allows for the development of straight line or linear motion that can also be produced in a positive (uphill) incline.
While each kind of shale shaker has a specific place that it will stand-out from other choices such as unit selling price, the ability to process heavy clays and rock or fines and ultra-fines, our overall preference of choice is the linear.

Hydrocyclones:  desander, desilter and mud cleaner combo machinery are all use various size of hydrocycles to filter the solids from the drilling mud. Each cone size has a micron cut point, which is the size of the smallest particle that the cone can pull out. The 4 inch cones have a micron cut of 20 microns and the 10 inch. have a 74 micron cut.

GN Drill Cuttings Solidification Equipment


GN Solids Control Co., Ltd has been upgrading solids control and drilling waste management systems since the establishment. Many types of cutting-edge equipment to treat drilling cuttings are provided to drill company in over 60 countries.

GN Solidification or GN Stabilization equipments are mainly used to treat drill cuttings or drill waste that discharged from GN Cuttings Dryer and GN Decanter Centrifuge or GN Hi-G Shaker.

GN Solidification Unit:

  1. The cost of treating OBM or WBM is relatively low. No further chemical waste generated in the solidification process.
  2. GN Solidification Unit is pretty convenient to operate and maintenance. Treating capacity can be adjusted easily by using variable speed screw conveyor.
  3. After solidified the OBM or WBM is changed into solid, which can be reused for approved farming.
  4. These solidified waste can be transported conveniently without any spill or leak.

The main component of GN Solidification Unit:

  1. Drill Cuttings Collection Hopper

Drill cuttings are sent to the collection hopper by a screw conveyor, which collect all the cuttings from centrifuge, cuttings dryer and drying shaker. One 10HP screw conveyor is fixed under the hopper to transfer these cuttings to High-shear mixer.

  1. Storage Box

There are two storage boxes: one is to storage absorber, the other is storage cements. Each storage box has one underneath screw conveyor; these two conveyors feed these materials into the high shear mixer.

  1. High-Shear Mixer

The high-shear mixer has a large force to mix all the OBM, WBM or SBM together with absorber and cements. After mixing thoroughly, it discharges the waste in solid. A catching tank can be used to storage and transport them to other places.

GN solidification units are largely used in drill cuttings management. The treating process is continually in worksite. By using different chemicals or absorbers, GN solidification unit can treat different OBM, WBM or SBM.

Do you know what is a mud gun ?

GN drilling fluid mud gun is a device used to agitate drilling mud on a drilling rig. More of a nozzle than a gun, a mud gun is connected to a pump to circulate the drilling mud and prevent the solids from settling in the mud tank. also depending on the number being used and the pit size. They are best used in tank corners to keep solids from settling and a mud agitator is placed in the tank center.

Mud Gun

GN premium quality mud gun is considered to be one of the longest lasting on the market today.Drilling mud is a wet substance that resembles a thick clay and is used to cool the drill head and carry the remnants of drilling to the surface in water well drilling and oil or gas drilling operations.

GNDC-40A Waste Management System for Russia

GN Solids Control is the first manufacturer for waste management systems which are accepted by Russian market. Just a few days ago, GN has delivered a complete set of waste management system to Russia. Now, GN’s vertical cuttings dryer and its waste management systems are most popular among the end users. Although it is a tough year for all the oil relating industries, GN also sells lots of waste management systems to the clients and receives good feedback.

GNDC-40A Waste Management System

GNDC-40A is one of the 2 standard drilling cuttings waste management systems GN designed for different jobsite requests. GNDC-40A is more suitable for the waste management jobsites which are alongside with the drilling rigs, in this system, there is no tank for containing the liquid phase from the centrifuge, and the centrifuge is hosted at a certain height so that the liquid discharged from the centrifuge flows directly to the active tank of solids control system easily. And when matching with an effective set of solids control system, this drilling waste management system could work continuously.

GNDC-40B is another standard design of drilling waste management system designed by GN Solids Control. It is more suitable for the mud companies or somewhere specially for treating the drilling waste cuttings. In some countries, there is no need for a drilling jobsite to have a waste management system, and the drilling cuttings are transported and collected in a special place for further treating. In this case, we use GNDC-40B, which has a tank for the liquid discharged from vertical cuttings dryer and another tank for the liquid finally discharged from the centrifuge.

Besides above mentioned 2 kinds of standard drilling cuttings waste management systems, GN also has the individual modules for waste management equipments, vertical cuttings dryer, high-G drying shaker and high speed decanter centrifuge, each one could be regarded and used separately. In the coming CIPPE Shanghai, GN will show such modules, welcome to come and see.
