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

High speed gravity separation technology help GN Solids to produce high quality decanter centrifuge, to serve domestic and overseas clients, by offering solids control and drilling waste management solutions, to develop GN into China high end technology company.
GN has various model centrifuges for option with different bowl size and different capacity, with different speed to separate different size particles.
1) GN 9inch baby centrifuge with only 9inch bowl size, and treating capacity will be 3-5m3/h. Normally, mining project / diamond drilling will require the small centrifuge to give better performance of mud treatment. What’s more, the cost of small centrifuge is very cheap.
2) GN 14inch bowl centrifuge with 14inch bowl size, and ration of length to diameter is over 3, to guarantee on the separation performance. The treating capacity for drilling mud can reach to 15m3/h to 25m3/h per the mud weight, viscosity etc. This model decanter centrifuge is equivalent to Swaco 518 centrifuge, Swaco 414 centrifuge, Derrick DE1000 centrifuge etc.
Many drilling contractor stop centrifuge renting service of Swaco branch or centrifuge renting service of Derrick company, they come to GN to buy their own centrifuges, and GN can offer training on centrifuge operation and maintenance. In long term, the drilling contractor can save lots of cost on mud treatment.
3) GN 18inch bowl centrifuge with 18inch bowl size and there are two options:
GNLW452 with 1800RPM bowl speed, which is specialized for barite recovery; the price is much better.
GNLW453-VFD with 0-2500RPM bowl speed, which is specialized for fast mud weight cutting, the centrifuge is controlled by VFD control panel & AC for cooling. The price is relatively higher.
4) GN 22inch bowl centrifuge and GN 30inch bowl centrifuge.
The big bowl big volume centrifuge is generally used for construction, TBM machine, Subway construction etc. In the mentioned project, large volume of mud will be engaged, and big capacity centrifuge is necessary to guarantee on the project period.

Chinese Spring Festival of New Year is coming very soon. GN Solids Control will shut down the factory during the holiday for about two weeks. After 4th of Feb, we shall come back to office. No worry, GN sales will be reachable any time, even in the holiday.
It is the time to see the New Year in and see the old year out. At this point, we want thanks for all people who help the growth and development of GN Solids, especially for GN partners and clients. With the purchaser order and support from partners and clients, GN can grow into China leading solids control brand, to serve more company and service for more projects.
About solids control equipment tender
When there is a tender, at least three solids control brand will compete to win the tender. What is the GN advantages when competing with US brand or other China brand ?
1) The first advantage of GN is on solids control equipment tender. Our sales people have strong reading ability to thick documents with quite a few pages, picking out the important parts, discuss about it and offer correspondence.
But GN generally doesn’t bid for overseas tender directly. We can support local company and the client can bid for tender in name of local company, but with technical support / commercial support from GN Solids Control.
2) GN can offer the most higher cost-effective solids control equipment from China. GN marketing position is only focus on high end client, with international standard products. Compared with US brand, GN can offer similar performance equipment with much better price. Compared with other China supplier, GN solids control product surely can work much better, no compares.
About registration to big companies
In the past years, GN Solids already successfully registered to many big drilling companies/ oil service companies. GN is registration supplier for CNOOC, PDVSA, NIDC, PDO, EDC, BAKER HUGHES, BAROID, etc.
In the New Year, we will be ready to register into supplier for more companies.
Shaker and mud cleaner is the most common item in solids control system. With high reliable shaker and mud cleaner, the mud system can work in higher efficiency, less maintenance, longer lifetime. GN shale shaker and mud cleaner, have been working for oil and gas drilling almost 10 years. With rich production experience combining with jobsite commissioning experience, GN have optimize the shaker and mud cleaner, make them much user friendly and high efficiency.
GN Solids Shale Shaker
GN Solids shaker have different models for option, including
2 panel shale shaker for mining/diamond drilling/ other small well drilling
3 panel shale shaker for CBM drilling/HDD drilling/Workover rig / Oil drilling etc.
4 panel shale shaker for oil and gas drilling, usually for deep well drilling rigs. This model GNZS594E-HB screen size is same as Swaco Mongoose screen. We can offer both composite material shaker screen and carbon steel frame shaker screen. After some years jobsite experience, composite material shaker screen can work better performance, and longer lifetime. Price of composite material screen is little higher than steel frame screen, but more cost-effective.
GN Solids Mud Cleaner
Mud cleaner is assembly of shakers, frameworks with desander cones and desilter cones, smaller footprint, and same function. Some client may not need the deck shaker, and we can offer the frameworks with desander cones and desilter cones. This is totally can be customized according to client’s need.
GN Solids mud cleaner model is decided by the model of shale shakers. We also have three models:
- Option 1: no shaker mud cleaner. Desander, desilter or assembly of desander and desilter
- Option 2: Mud cleaner with 3 panel shaker
- Option 3: Mud cleaner with 4 panel shaker
Sometimes, the selection of shaker is depending on the tender requirements. If the client buy and use it for themselves, they can choose better and lower cost models.
Welcome to GN Solids Control for any consultant for Solids Control questions.
Good news ! We are awarded another purchase order from Middle East HDD client. The client is local biggest horizontal directional drilling private company, and just wins contracts from government gas dept. They need more HDD rigs, HDD mud equipment to continue the project.
We have offered several times quotation in last year, including:
1) Double deck shale shaker with coarse steel screen.
The client need double deck shaker, up deck 2mm shaker screen to remove all stones, down deck 0.5mm shaker screen to remove fine solids. The client don’t like carbon steel screen, and require PU material screen for longer lifetime.
We have rich experience in double deck linear motion shale shaker manufacturing, as well as PU material shaker screen. We have confidence the client give issue repeated order if they need more.
2) Assembly unit with desander cones and desilter cones
The client don’t need the mud cleaner, three in one unit which include desander cones, desilter cones and down deck shaker. Instead, he require assembly unit with desander and desilter cones. This is good to save footprint in mud tanks, and also lower down the unit price, spare parts cost.
We customize the assembly unit as per the request from client.
3) 3ea centrifugal pump
2ea centrifugal pump feed to the assembly unit of desander cones and desilter cones. 1ea centrifugal pump as backup. Or will be used in other application.
4) Economic standard mud system
As the client have different project, and they also need one compact mud system, economic standard, GNMS-500D. This unit is generally used for piling project, 2 stage separation with screen / desander cones, to remove the big solids.
We also have other capacity for option, including 200gpm GNMS-200D, 500gpm GNMS-500D, 1000gpm GNMS-1000D.If the client project require better fine solids removal, may require higher standard mud system with 4 phase separation. We can offer the turnkey solution per client’s request.
As the drilling operation going on, more and more solids will come into the mud, lead to the arising of mud weight. The change of mud weight is not good for drilling operation. Decanter centrifuge is required to remove the solids, and control the mud weight.
GN Solids Control is China leading brand for oil drilling mud decanter centrifuge. We have different model centrifuge for option, including:
9 inch bowl baby centrifuge, this is popular for mining/ waste water treatment.
14inch bowl high speed centrifuge, this model centrifuge is equivalent to SWACO 518 centrifuge / Derrick DE1000 centrifuge. Fixed speed centrifuge and variable speed is available per the client’s request
18inch bowl big volume centrifuge, this model centrifuge has two options: GNLW452 and GNLW453. The two option centrifuge is used differently. GNLW452 is very popular for HDD drilling, or for barite recovery; GNLW453 variable speed can be used for fast drilling
22inch bowl big capacity centrifuge, this is only GNLW553-VFD centrifuge for tunneling or other field fast drilling.
30inch bowl centrifuge is designed for industry application.
For oil drilling application mud weight control, we recommend fixed speed GNLW363CG 14inch bowl centrifuge for better option.
- Firstly, fixed speed centrifuge is much easier for operation than variable speed centrifuge.
- Secondly, we can offer 2700RPM bowl speed centrifuge, 3200RPM pulley with belt as backup.
- Lastly, the fixed speed centrifuge is much better price than variable speed centrifuge.
Centrifuge feed pump, we recommend screw pump, positive displacement pump. The pump motor is controlled by the centrifuge control panel.
Telescopic skid is for option. The client can compare the price from GN, and local fabrication price.
Except for centrifuge, vertical cuttings dryer is another popular item for oil drilling waste management. The client needs it to recover the valuable oil based mud and return it back for drilling operation. We have two options: GNCD930 series cuttings dryer and GNCD730 series cuttings dryer. The client can choose the proper model per request.
