Mud plant is very important application in solids control industry for oil and gas drilling industry. It is used to further treat and to storage the drilling mud back from the solids control system of rig site and get the drilling mud to be ready for next time use.

drilling mud system

What equipment is used for a mud plant?

Normally, the mud plants’ main application is for storage the drilling mud, and adding some necessary chemicals into the mud. So the commonly used equipment is:

  1. Mud agitators. Where there’s mud, there’s agitator. Because if the mud is still for a while, the heavy components in the mud would settle down to the bottom and as long as they settle down, it is difficult or even impossible to re-stir them. So mud agitator is a continuously working equipment in a mud plant. GNJBQ series mud agitators covers all necessary models for oil and gas use mud agitators, it is compact in structure and with a powerful strength. Based on your tank depth, GN could recommend you with suitable model of mud agitator.
  2. Mud guns. Normally, the mud gun and mud agitator are used in pairs, like besides each mud agitator, there’s a mud gun. As the mud agitator is working in the middle of the tank, the mud gun is used to stir the mud in the tank corner. GN mud gun is suitable for high pressure up to 6.4 Mpa, and there are fixed nozzle models and rotary nozzle models for option. In addition to the main application as stirring the drilling mud at tank corner, the mud gun could also be used for transporting the mud from one tank to another.
  3. Jet mixing system. It is combined by a jet mixing hopper and a feeding pump for the hopper. For making the old mud to be suitable for future use, we need to add some chemicals into the mud. GNSLS series hoppers are made of stainless steel, with same or even better material than USA brands and with a longer service life. GNSB series centrifugal pumps are interchangeable with MISSION pump with spare parts. It could be used as feeding pump for hopper and desander or desilter’s feeding pump.

Recycle the drilling mud that lubricate the drilling bits.

The drilling mud solids control system is for filter away danger solids phase that contain in the drilling mud and reuse the needed solid phase.  The task is to keep drilling fluids in stable performance status.  There are several machinery that will need to perform the tasks.

The result of consist performance of drilling mud is avoid the blocking and damage of the oil and gas channel. It reduce the well drilling torque and friction drag and reduce the pressure oscillation of the annular air suction.  It also increase the velocity of the well drilling, extend life of the drill bit, reduce wear of the equipment.

drilling mud system

There are  five steps of filtering process that require five solids control machinery that will do  filter screening, degassing the mud, desanding the mud, desilting the mud, centrifuge force separation and demand of weighting up mud. The consist work flow between every solids control equipment use in the whole system is very important.   Level one to five level of output of the mud should be matched each other and the interval of separation size should be appropriate and have a certain overlap.  The result of the smaller solids which are not filter by the upper can be filter in the next controlled level.

With the development of well drilling technology, mud mixing system plays an important role in drilling operation. The various kinds of solids control systems function at the same time. Regardless the different kind of the solids control system, it’s basic function will not changed. It is depend on organic combination of mechanical removal equipments, drilling fluid mud tanks and other auxiliary equipments to accomplish the basic function:  Recycle the drilling mud that lubricate the drilling bits

GN Solids Control just received another order of 2 pieces decanter centrifuges lately. This kind of two variable speed decanter centrifuges will be used in Of india oil and gas drilling worksites.
GN Solids Control had implemented this centrifuge project because this May although the oil value has been fluctuated since the ending of last year. The end consumer had been carefully compared GN decanter centrifuges with some additional world famous decanter centrifuges manufacturers, but at last they are sure by the excellent working efficiency and good quality of GN centrifuges. This Indian customer also sent some planners to inspect GN decanter centrifuges before they make the final judgement to purchase. While they’re fairly satisfied with the hundreds of profitable decanter centrifuges are working inside over 60 countries. GN Solids Control showed parts of the former video clips or pictures to this buyer, which helped to promote the actual win-win cooperation.


GN decanter centrifuges are effectively utilised in the oil and gas area with regard to drilling waste management. Diverse cuttings can be separated out there when using appropriate rotating velocity. Barite can be recovered when you use rotating speed 1800rpm; energetic drilling fluids can be used again when set the centrifuge to the speed of 3000rpm. Sometimes, GN recommends applying 2500 rpm rotating rate to dilute the going mud.
Besides these two decanter centrifuges, this Indian customer also purchased four attach pumps (positive displacement pumps): 2 sets are used since the feeding pumps while there are usually another 2 sets to get backup. Some spare parts for that two decanter centrifuges and also 4 screw pumps can also be purchased in case they’re busted.
Until now, GN Solids control Co, Ltd has provided centrifuges to most of the drilling worksites in over 60 international locations. GN has been manufacturing solids manage and drilling waste management systems since the year connected with 2007. Although GN is actually a young company, GN gets known by more and more worldwide clients.

Not long ago, GN solids control finished the manufacture for several units de-sanding product used for bored piling job. These de-sanding units usually are separately for the customer received from Saudi Arabia, Singapore, Myanmar and a China domestic client. Besides the bored piling assignments, this small footprint along with cost effective machine can also be traditionally used in TBM and HARD DISK DRIVE projects.

GN’s de-sanding device is a composition unit such as the primary shale shaker and cyclone unit with 2 development solids separation function. The significant principle of GN De-sanding unit is as follow:
1 ) A Pit pump will certainly suck the drilling body fluids from the mud pit and also transfer to the de-sanding product shale shaker for coarse hues separation. Please note that the opening pump is an extra system which the customer can choose to have from GN solids conrol or obtain locally.
2 . The liquefied goes through the mesh display screen of 20/40 mesh will probably temporally stored in the below located mud catching fish tank waiting to be transferred to often the cyclone unit for further separating.
3. The self-contained centrifugal pump transfers the water mud to the de-sander/de-silter cyclone for finer solids parting. After separated by the cyclone units, the clean liquefied would overflow to any where customer prefer.
bored pile desander
GN’s de-sanding unit is classified because 200GPM, 500GPM and 1000GPM with different model as GNMS-200D, GNMS-500D and GNMS-1000D.

About consideration of cost conserving and flexibility, this de-sanding system is not equipped with mud storage space tank. The operator might get the mud tank in your area and connect with GN’s de-sanding unit easily with pipe. The operator even can obtain a separate skid mounted airliner mud mixer to connect having mud tank to amalgamated a complete mud recycling program. Thus the user could get a new self-contained mud system which may be used for horizontal directional going which will request for both soil recycling and mud mixing.
Considerably better solution for your piling job mud recycling, for more information, make sure you no hesitate to contact along with GN Solids Control.

In olive oil industry, decanter centrifuge is actually widely used equipment for drilling mud recycling and waste slurry separation. The centrifuge with bowl diameter bigger than 16 inch is always named as big bowl. Evaluating with the small bowl centrifuge involving 14 inch, the big dish has larger capacity. With regards to GN solids control, the bowl is with 22 ” bowl diameter, model GNLW553C-VFD.

Features of GN Big Bowl decanter Centrifuge
GN’s big dish material is using duplex stainless-steel of 2205, processed simply by centrifugal casting to ensure the considerably better bowl balance. Also this fabric has a better performance on corrosion-resistance.
The protection of the attach propeller is tungsten carbide tiles to enhance the anti-wear features. Long lifetime will save the cost for repairing repairs and maintanance.
GN’s big bowl has VFD control panel to achieve stepless speed change for different performing requirements.
GN’s centrifuge, irrespective of big bowl or normal size bowl, is driven by 3 motors. This 22 ” big bowl is powered by a 120 HP principal motor and a 50HP again motor. Via the planetary gearbox, the back motor might drive the screw propeller to rotate same path as the bowl but diverse speed, so that the solids may be pushed out from the inside the pan.

2015.11.05 Big Bowl Big Volume decanter centrifuge shipping to Australia
Application of GN Big Dish Centrifuge
GN’s big bowl centrifuge could be used in most important solids control system regarding barite recovery. When it do that job, it always extends at a low speed, hence slurry would be fed within the big bowl at more substantial flow rate. Running from high speed of 2500 rpm, it could produce G pressure nearly 2000. It could be employed as find solids spliting up equipment.
Besides, GN solids control has already successfully introduced this big bowl directly into dewatering system which is used to clear out the accumulated ultra locate solids in the drilling off-road after several times recycling. In a of GN’s dewatering technique to a Southeast Asia consumer, this big bowl is usually adopted as a separator to get fine solids and normal water. Including the flocculation agent combining system, this dewatering technique are designed to be packed within a container for easy travelling and indoor operation.
