Shale shaker (linear motion) shale shaker, desander and desilter are composite of the complete line solids control system together with decanter centrifuge, vacuum degasser and poor boy degasser. Their main function is to remove the big solids step by step in the drilling fluids, to reduce the mud weight and make the drilling fluids qualified for the drilling function.
Recently, another 3 sets 4-class drilling fluids cleaning system have been finished and ready for dispatch. The 3 sets mud cleaning systems are composed of 4-class mud cleaning equipment as following:
1) A double deck shale shaker desander with 2 ea 10 inch desander cone.
2) A double deck shale shaker desilter with 12 ea 4 inch desilter cone.
3) 2 ea middle speed decanter centrifuge with variable speed control to reduce the mud weight.
Many people may be wondering, where is the shale shaker? Exactly, there is no separate shale shaker machine seen on the system. Why we say it is a full 4-class mud solids control cleaning system? The reason is that, the bottom shaker deck on the double deck desander and double deck desilter will be used as shale shaker. It means, the system includes 2 ea solids control shale shaker, 1 ea desander and 1 ea desilter, and then 2 ea decanter centrifuge. It is a high standard drilling fluids mud cleaning system, it can meet the requirement of big depth drilling activities.
It is not the first time CNPC bought this kind of design drilling fluids cleaning systems from GN. At the end of year 2015, CNPC order 3 sets the system design mud system and send their engineering team and management team come and check. They are very happy with GN design and happy with GN quality. Good quality and reliable services, as well as the competitive price compared with the quality. It is the reason why CNPC choose GN through so many Chinese suppliers. It is also the reason why GN brand expanded so fast.

Decanter centrifuge is widely used in oil and gas drilling field. They have many applications.
The main application of decanter centrifuge for oil and gas drilling field
1) Middle speed centrifuge is widely used in solids mud system to for the recovery of barite. It can reduce the mud weight.
2) Decanter centrifuge can be used in drilling waste management system to treat water based mud and cuttings, oil based mud and cuttings.
3) Decanter centrifuge can be used for waste water treatment.
4) Decanter centrifuge can also be used together with chemical dosing system as a dewatering unit.
For different applications the layout of the decanter centrifuge is different.
1) When used in the solids control system for barite recovery, it is usually put on the tank top after other solids control equipment, like shale shaker, desander, desilter, vacuum degasser, etc…
2) When used together with chemical dosing system as a dewatering unit, it is normally put insides the chemical system container, or on the top of the container. Also it may be put outside.
3) The most normal way is to put on a telescopic skid. The skid will be higher than the mud tanks. In this case, the clean mud from decanter centrifuge will be flow to mud tanks or next process under gravity. It can save a transfer pump and storage tank.
GN portable design telescopic skid is welcomed by the oil and gas drilling field. It is compact design with small footprint. It is accordance with HSE requirement, and contains ladders, guardrails, walkways. The positive pressurized VFD control and the screw feeding pump for the decanter centrifuge can both be mounted on the skid under the centrifuge. They do not need to be removed during shipment.
When the telescopic skid need to be shipped from one side to another, you only need to reduce the height by pin, other accessories can all be mounted on the skid. And the walkways are designed to suits both high height and the low height.

The rig sites are normally far away from human area. Well well drilling is the most fast and most convenient way for the water supply.
GN Solids Control engineer just came back from a middle east job site. He finished the first time commissioning and training of 1 set GNMS-500G water well drilling mud system. The 500GPM mud system is design and made for their oil rigs.
The system is composed of a single deck linear motion shale shaker, a hydro cyclone desilter separator, a drilling fluids mixing system, feeding pump, mixing pump, the explosion proof electric control system, trailer skid mud tank and electrical lighting systems.
For a compact design, GN put the feeding pump for hydro cyclone desilter, and the mud mixing pump on the skid.
In order to get a bigger usable capacity, GN designed the mud tank with 3 m width. Not only in China, but also in many other countries, 3 m is the normal width limitation for inland shipment. GN make all the sand gates build-in type. In this case, it will not over the tank width scope.
Clients request a mobile unit for fast movement. In order to save the cost of clients, GN Solids Control recommend client to source trailer skid locally and buy complete mud system from GN. GN Solids Control customize the system suitable for trailer skid. There are container corner blocks at each tank corner. The tank can be out and locked on the trailer skid like a container.
