GN mud system have been exporting to over 60 countries and areas. The mud system can be used for oil & gas drilling, HDD, water well drilling, geothermal drilling, etc.

Recently, I am busy with two projects for Africa. They are both water well drilling companies. But as the drilling rig size is different, and they have different requirement and budget for the mud system. We offer different configurations.

500gpm mud system for first client. The water well drilling depth will not deep, and the client need simple mud system, and we offer mud system with below equipment list:

• 1) 1ea shale shaker, equipped with 3panel shaker screen, treating capacity 120m3/h for light mud or water treatment.
• 2) 2ea mud agitator, to mixing the mud and suspending the heavy mud to avoid settlement.
• 3) 1ea mixing hopper, to mixing bentonite or barite
• 4) 1ea centrifugal pump, to give mixing power for the mixing hopper. Can also work to transfer the mud out when the mixing hopper stop work.
• 5) 1ea mud tank with 9m in length, 2.2m in width and 2.2m in height. This design mud tank can be put into container for shipment, easier transportation and much better sea freight cost.

All above item is installed on the mud tank, and the mud system can working well for drilling rigs & mud pumps.

500gpm mud system for another client. The water well drilling depth is deeper to 1000m. The client rig is from Drillmec, and he need 3 stage treatment mud system. And we offer mud system with equipment list below:

• 1) 1ea shale shaker, equipped with 3panel shaker screen, treating capacity 120m3/h for light mud or water treatment.

• 3) Mixing hopper, mixing pump, trailer mounted tanks is equipped for the system.

We normally customize mud system for client, if you need any support, pls contact GN Solids Control.

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.

GN Solids Control main business is in oil drilling & HDD field, for drilling mud system and waste management. For smaller percentage business, GN get it from piling, mining and road construction which require compact and small mud system to clean and recycle the mud. GN offer desanding plant to achieve the target for client.

Recently, we just ship 3 sets desanding plant to one piling client to Southeast Asia. The client issue the PO in the beginning of November and come to GN factory for the inspection. The purchased desanding plant model is GNMS-1000D, with 2ea 10inch desanding cyclones to reach up to 1000gpm treating capacity.

Actually, we attended Bauma exhibition last month, bring the desanding plant there for show. Many clients with piling projects, mining slurry water project, road construction etc. came to GN Solids booth for consulting.

One client from Mexico, they have Derrick desanding plant for the mining slurry process for now. The performance is very good, price is also very higher. The client is trying to find equivalent equipment with lower cost. After we have short meeting to discuss on the working flow, the client is very satisfied with GN desanding plant and also price. He promised to buy one set very soon for test.

Another client from Australia is doing HDD project, he want to find HDD rig and mud system from the show. After he knows GN, we recommend good brand HDD rig company and GN mud system. With quite a lot HDD project list brochure for China and Australia market, the client is convinced that GN can supply good product and high quality service to him. Very soon, the client bought one sets 500gpm mud system for project.

One client from Marocco are needing separation machines to treat the slurry from mining operation. And we quote to them in the show directly. Technical evaluation is under process, and we are waiting for positive feedback from client.

Centrifuge tank works as second phase separation in mud cleaning system. This part is necessary for oil & gas drilling, for deep and complex geological structure drilling operations. Centrifuge tank generally have below options for drilling company:

Option 1: rent centrifuge from solids control service / centrifuge rental company

Compared with other solids control equipment, centrifuge price is higher, as well as the higher cost on maintenance and manpower cost. As the centrifuge is not working during all drilling operations, some drilling company only rent the centrifuge when they need it.  For short terms, the rental service is helpful to drilling contractors, saving cost, time and saving works.

But from long terms, rental centrifuge will lead to higher cost, not as cost-effective as having it’s own equipment.

Option 2: buying centrifuge and train the workers to do the job

If the drilling company have many drilling rigs, and the drilling operations will last for many years. Having their own centrifuge will be much better.

GN Solids Control is China leading centrifuge manufacturer, can sell centrifuge to client or rent centrifuge to client in some area with GN office.

GN can offer middle speed centrifuge, high speed centrifuge, fixed speed centrifuge or variable speed centrifuge, motor drive centrifuge, hydraulic centrifuge etc.

If the client have enough budget, we recommend 2ea VFD centrifuge for each rigsite.  The VFD centrifuge can work flexible at any bowl speed, conveyor speed or differential speed, to achieve the best performance.

If the client budget in tight, we recommend 1ea VFD centrifuge & 1ea fixed speed centrifuge. The VFD centrifuge can work as flexible role and the fixed speed centrifuge can lower down the total cost.

Even the fixed speed centrifuge can change speed, by replacing pulley with belt, just taking more time and more manpower than VFD centrifuge.

If you need more information about decanter centrifuge, pls contact us freely.

GN Solids Control has been working for oil & gas drilling field for about 10 years. In past years, we accumulate rich experience in mud system manufacturing, sales, operation, and maintenance. Recently, we have inquiry from Africa about 1000bbl mud system for oil drilling rig, and we give below proposal:

1) shale shaker tank

The first tank, shaker tank is equipped with 2 sets shale shaker, 1 set mud cleaner, agitators, centrifugal pumps etc.

Mud tank: 1 set, tank size 11000 X 2100 X 2150mm. The mud tank is oilfield skid mounted tank, the most popular tank type for oil drilling.

Shale shaker: we recommend GNZS594 shale shaker for better working performance, longer shaker deck and composite material screen with long lifetime.  GN composite material screen is replacement for Swaco Mongoose

Mud cleaner: we recommend mud cleaner with 2ea desander cyclones and 12ea desilter cyclones. The deck shaker is same as GNZS594 shaker, thus same type shaker screen is required, no need backup different type screens.

Centrifugal pump is equipped to feeding the mud cleaner cyclones.

The third compartment in mud tank is clean mud after treatment; mud agitator is equipped to suspending the mud.

2) Decanter centrifuge tank

The second tank, centrifuge tank is equipped with 1ea middle speed centrifuge, jet mud hopper and mixing pump.

The centrifuge GNLW452 middle speed centrifuge is used to remove the barite in the mud or other big solids particles.

The mud hopper and mixing pump is used to mixing chemicals into the drilling mud, to adjust the mud weight and mud viscosity.

Mud tank: 1 set, tank size 11000 X 2100 X 2150mm. The mud tank is oilfield skid mounted tank, the most popular tank type for oil drilling.

3) Mud storage tanks

There are another two mud tanks for mud storage, same tank size to shaker tank. The tank is equipped with necessary mud agitators, mud guns and necessary pipelines and other spares.

If you need any solids control equipment or mud system, pls contact GN freely.

Many China drilling contractor or oil service company have business in Africa, they bring the high technology there, help the economy development of the local market, and improve the lift of local people.

Recently,  one China government company CNPC have get some project in Africa, and give purchase order to buy drilling waste management package from GN Solids Control.  The package including below items:

1) Mud tanks with High G drying shaker

GN High G drying shaker is very popular to treat the water based mud drilling cuttings discharged from shale shaker. The patent 4 panel shaker is replacement for Swaco Mongoose.

If for oil based mud, vertical cuttings dryer will give much better working performance. However, the purchase cost and maintenance cost of Vertical cuttings dryer will be much higher than High G drying shaker. The client can make decision based on the Mud condition, budget and the special requirement from the owner.

2) Mud tanks with decanter centrifuge & flocculent unit

The WBM drilling cuttings, after treatment of High G drying shaker, the separated liquid should be transfer to decanter centrifuge for 2^nd step treatment. GN decanter centrifuge have different model for option. The most popular model is 14inch bowl centrifuge GNLW363.

This decanter centrifuge is equivalent to Derrick DE1000/ Swaco 518. And we have fixed speed type and variable speed type for option.

If ultra fine solids in liquid cannot be separated by centrifuge, flocculent unit is required to coagulate the ultra fine solids to big particles, then separated by centrifuge.

3) Auxiliary equipment, including screw conveyor, transfer pumps, feeding pumps, is included for the package.

Except above part, GN can offer different model shaker screens to replace the expensive screens from original seller. The screens including:

• GN replacement screen for Derrick FLC500 shaker, Derrick FLC2000 shaker;
• GN replacement screen for Swaco Mongoose shaker
• GN replacement screen for NOV brandt king cobra shaker /VSM shaker

……

Even the oil drilling market is very down, we still can receive some purchase orders from old clients. Recently, we finish production for waste management system, and is exporting to Uganda, Africa now. China Oilfield Services Limited (COSL) bought the equipment and doing drilling operations there.  The project including below items:

1) High G dryer with collection tank beneath.

The High G dryer is GN 4 panel shale shaker with up to 8G vibration motor, and 4pcs composite material shaker screen. The high G force and longer deck can make the solids discharge much dryer, which is easier for transportation.  The clean mud will drop down to the beneath catch tank.

2) High speed decanter centrifuge with mud catch tank

The decanter centrifuge is GN 14inch high speed centrifuge, which is the most popular model for oil & gas drilling. The 14inch centrifuge is equivalent to Swaco 518 centrifuge or Derrick DE1000 centrifuge. Many client used Swaco/Derrick centrifuge before, and shift to GN after knowing GN strength and high quality of GN centrifuge.

The high speed centrifuge can be set to 3200RPM, which can separate 2-5microns fine solids. The clean drilling mud drop down to the catch tank below. Then, the screw pump will transfer the clean mud back to drilling active tanks for reuse.

Above equipment system is more proper for water based mud treatment. For oil based mud cuttings treatment, Vertical cuttings dryer will give much better performance. GN vertical cuttings dryer have been put into market for over 3 years. The separation  point is mainly depends on the screen basket, 0.25mm/0.35mm/0.5mm opening for options.

As China & USA leading brand for solids control / drilling waste management, GN Solids Control have various product to meet the different needs, including vertical cuttings dryer, high G dryer, decanter centrifuge, solidification unit, thermal desorption unit etc.
