About 5 years ago, one old client from India bought 2sets complete mud tank system for their oil drilling rigs. During the past years, we continuously support the client with timely after sales service, and offer requested spare parts in shortest time. The client knows GN many years, and IS satisfy with the past experience with GN. Recently, the client get new project and want to renew the mud tank system. New order of several sets shale shaker & mud cleaner issued to GN, including some centrifugal pump, shear pump, mud hopper, mud agitators etc.

Main features of GN shale shaker

Mud treatment is required in many different industries.  For GN Solids, the most popular mud treatment is oil drilling mud treatment, or HDD mud treatment.  In recent years, we have more and more project from other industry mud treatment, like piling mud, TBM mud treatment, or construction mud treatment. One batch of mud separation equipment for US client, ready for delivery. The client will use the equipment to treat the construction mud.

1) High G drying shaker with catch tank

The mud will be collected by one big hopper with wide opening, and then transfer to high G drying shaker, to separate the big solids particles.

GN high G drying shaker is equipped with 4 panel composite material shaker screen or coarse steel screen per client’s request. The longer shaker deck can give better separation, and make the solids discharge as dry as possible. The super G force also very important to the dryness of discharge solids.

The high G drying shaker is seated on the catch tank with submersible slurry pump. The slurry pump can suck the mud and feeding to next unit for further treatment.

Most of client will choose skid mounted mud system, to put the mud system on the truck for transportation from site to site. Some client will prefer to trailer mounted mud system with single axle or double axles. The trailer mounted mud system allow client to move it by truck head, to hook the mud system and pull it from site to site, which will be much convenient from the close project. Recently, we have one client from North Africa. The client need mud system for water well drilling and we already discuss the inquiry for about one year, finally the client give us order for one set 500gpm trailer mounted mud system. We source the trailer from trailer company, and weld the tank upside by ourselves, and then match the proper model shale shaker, mud cleaner, pumps, hopper etc. to complete the mud system.

Oily sludge is difficult to reuse because it is mixture of waste solids, oil and water. If not treatment, Oily sludge is hazardous to environment, may contaminate the soil, water and air. The oily sludge can be from refinery, drilling waste or tank cleaning etc. From technology, if the oily sludge can be separated to oil, water and solids, the separated oil can be reused or resell, the separated water can be used for green or project.  After well separation, the oily sludge can be effectively become useful material.

We just finish the tourist trip to Thailand and back to China yesterday. As the leader manufacturer for solids control equipment & mud system, we are always available even when we were for Tourist in Thailand. We took our computer and other data, and ready to give fast response once request by clients.

During the tourism, we got inquiry from West Africa, requiring big mud system for HDD project. The client use America brand mud system before, and use American Augers HDD rig. They cooperate with Government, and do lots of HDD project in local country and subsidiaries.

GN has many different model decanter centrifuge for different application. For now, GN have below bowl size centrifuge for option, including:

• 9 inch baby centrifuge with only 220mm bowl diameter; It can only be used for diamond drilling, mining, area with request small capacity treatment. The treating capacity can be only 3-5m3/h.
• 14inch bowl centrifuge with 360mm bowl diameter; it can be used for oil drilling mud system, to cut down the mud weight or recover barite. The treating capacity can reach up to 15-25m3/h.
• 18inch bowl centrifuge with 450mm bowl diameter; it can be used for fast drilling, the treating capacity can reach up to 30-40m3/h.
• 22inch bowl centrifuge with 550mm bowl diameter, similar function to 18inch bowl centrifuge.
• 30inch bowl centrifuge with 760mm bowl diameter. This is used for TBM big project, need large treating capacity for mud. The treating capacity can reach up to about 100m3/h.

The client can choose different model centrifuge as per the project request, engineer recommendation, budget etc. Pls contact us and let us know your project requirement, then we can offer your proper model.

As sales for Africa region, we follow the Africa clients who have potential requirement for solids control equipment, mud system, shaker screen, or other related spare parts. One Africa Drilling Company send inquiry to us from early of 2016. From then, we continuously follow the client, to offer quotation, mud system drawing, answers for many questions. After about one year communication, we finally got the purchase order. It is one 500gpm trailer mounted mud system with shaker; mud cleaner and other necessary solids control parts.

Details of the system configuration as below:

1) GNZS703 shale shaker, with composite material shaker screen to ensure the longer working time and better separation performance.  The shaker is equipped with Italy OLI brand motor, much reliable than other brand. The shaker screen is locked by wedge, which is easy to install and dismounting, save time when replace the shaker screen.

2) GNZJ703 Mud Cleaner. The mud cleaner is combination of three unit, including down deck shale shaker, desander and desilter assembly. The down deck shaker is same as GNZS703 shale shaker, but with higher API size screen (API 120, API 140 etc.).  The desander and desilter are made of PU material, much anti-corrosive material. The raw material and design are almost same, just the size is different. The desander is 10inch and desilter is 4inch.

3) Other necessary solids control equipment including mud agitator, mud gun, centrifugal pump etc. The mud agitator is used to suspend the heavy solids in mud to avoid settlement, and the mud gun can be used to flush the tank when finish work. The centrifugal pump is used to suck mud and feed to desander cones and desilter cones.  The two sets centrifugal pump will consume most power in the system.

4) All above mud equipment will be installing on trailer mounted mud tank. The mud tank is building and welding on the lower trailer chassis, easy for short distance movement.

If you are in need of any trailer mounted mud tank system, pls contact GN freely.

Desander and desilter are the second phase separation and third phase separation in oil drilling solids control system. There are different type desander and desilter for option, we may firstly to know the difference and advantages of each type, then we can know how to make choice for project.

 First type: Desander/Desilter without downstream drying shale shaker

1) Small footprint, economic choice, no consumable screens

2) For oil gas drilling un-weighted drilling mud

3) Only for wet cuttings, not recommended for weighted mud and drying solids

Second type: Desander/Desilter with Mini 2panel Shale Shaker

1) Small footprint, economic choice, acceptable drying solids

Third type: Desander/Desilter with 3panel Shale Shaker

1) Big capacity, drying solids
