As we all know drilling mud is one of the most important middle material in the drilling program. As usually ,The solid control system refers to the degasser, shale shaker, desander, desilter, micro desilter, desanding and cleaning device, desilting cleaner, centrifuge and mud tank. That is a whole set of system according to the requirements of solid control. The selection of solid control system is mainly based on the following principles
1 ,Type and size of particles to be removed or suppressed
2,Cost of drilling fluid
3, Liquid solid cost ratio of drilling fluid
4. The quality of drilling fluid that needs to be maintained during drilling is poor, and environmental factors are taught
5, freight and other miscellaneous expenses;
6 ,density of drilling fluid used;
7, mechanical ROP, solid removal rate and circulation rate.
Select the suitable solids control equipment will help to reduce the drilling cost and improve working efficiency.
There are seven basic systems for solid phase control. The first system is the most basic, which is suitable for non weighted drilling fluid. The system largely rely on desander and desilter. During fast drilling, the desilter should be started continuously. It should be noted that if we can concentrate the drill and make it more concentrated than the diluent, we can use “low-density drilling fluid” for the desilter. The second system added Decanter centrifuge based on the first solids control system. Decanter centrifuge are used to remove out the tiny particle. It can clean mud and also reduce mud gravity. The 2 system are used in most drilling project. However , in some special project, the system will require several units hydrocyclone and Decanter centrifuge to teat expensive drilling mud to recycle the mud as much as possible.
However, shale shaker, degasser, desander, desilter, decanter centrifuge are the basic solids control equipment. GN can provide all these equipment and customized produce the system according to client requirement. If you have demanded, welcome to contact us.

Solid control is very critical during the oil and gas drilling process
Solid control is very critical during the oil and gas drilling process, it will maintain the required property of the drilling mud and remove the low gravity solids from the liquid, and finally can make the drilling mud which could be reused and recycled in the drilling mud system. A good solid control process could increase the rate of penetration, reduce the wear and tear of the drilling equipment, such as the pistons, liners of the mud pump and allow for better hole cleaning.
GN’s solid control equipment can perform very well during the drilling process, and most of them are specially designed as compact, skid mounted and very mobile. One consumable part for the solid control equipment is the shale shaker screen. This year GN made a lot of effort in the improvement for the screens. GN launched its second facility specially for making the shaker screens of composite frame. Now GN has composite frame replacement screens available for MONGOOSE, KING COBRA/ VENOM, FLUID SYSTEM.
Now GN plans to promote its composite screens aggressively in North America, and it’s looking for new distributors. The ideal candidate will be an experienced one who has been in the solid control business for years, and has pretty mature distribution channel. So once combined GN’s composite screens with the distributor’s channel strength, it will quickly generate great revenues, and it will be a win-win situation. Better the candidate has many warehouses in different locations, especially in the key oil and gas basins. That will make us serve the local customers better. Once qualified, GN will give the candidate distributor great support, in terms of payment term, pricing, packaging, branding and so on. GN’s goal is going together with a great company to achieve great success.
That’s the brief introduction about GN’s screen strategy. GN would like to hear from you. Welcome to visit www.gnsolidsamerica.com and please send your ideas to USA@gnsolidscontrol.com .
GN Solids America LLC’s solids control machinery meet the goal of environment protection.
While Oil rig perform the drilling into the earth core, it needs to break soil and rocks apart. Some layers often is harder than other so drilling operation will use additive to strength the drill bit to break the layer. The additive that uses combine the rock sometimes will cause the harm of environment.
Underground of earth is not totally solid and sometime it contains the layer of water like underground river. When water mix with the drilling process, it contains several of heavy metal ion and anion. Such content in water will change the stability of the drilling fluid that affect the performance of the fluid. When water is in the drilling fluid increasing, the various additives will be added into the drilling fluid. The mixture of drilling fluid and additive is harmful to the environment if reach to surface and not properly treated.
The calcium, gypsum. Salt to name a few that mixing with additive is common and needed but harmful to environment. The mud treating system is serving the purpose to contain, filter and recondition the drilling mud for continuous usage.
GN Solids America LLC’s advantage is we are the solids control manufacture that made the whole solids control machinery which is custom made the whole mud recycle system to meet specific project’s need for our customers. Our customer are ensure we provide the solids control machinery to meet local environmental standard around the world and dealing with manufacture them self to ensure the best possible price to keep overall cost of rig operation as consist as possible. We provide consist stocks of parts and tech personals ready at the request of customers by moment’s notice. There are lots of manufactures in China who can make less-costly machinery and system but adding other facts for operation consideration, GN Solids America is the choice of obvious.
GN Solids America LLC’s machinery use in solids control system
Drilling fluid serve as lubricant for the drilling bit and it needs filter the solids that produce while the drill bit drilling into earth. While drilling into the earth, broken solids from the underground mix into the drilling fluid will decrease the lubricant performance and will cost damages of the drill bit that will also result drilling operation on hold that leads increase of operation cost. The solids control machinery ensure the solids separation to ensure the continues operation of the drilling rig to achieve consist operation cost and time efficiency. Shale shaker, Vacuum degasser, mud cleaner and centrifuge are the basic machinery to achieve the filtrations of solids for the drilling fluid.
Shale shaker is the first step solids control machinery to filter the drilling fluid that filter the large solids by continue shaking force by motors and various API numbers of shale shaker screen. While it is the first step of filtrations, the result will determine following machineries’ filtering process.
Vacuum degasser is use pumps that create suction of pressure in the vacuum tank. The bubble in the drilling fluid need to remove cause the harmful gas that might cause explosion and need the balance of chemical compound of the drilling fluid.
Mud cleaner is continue process of the filtration after the shale shaker by eliminating smaller solids that pass through shale shaker screen. The desander, desilter and shale shaker combine as mud cleaner and use different of API number screen to achieve mid level of filtration solids fluids.
Centrifuge is machinery use centrifugal force by rotating in rpm force to achieve remove finest solid, recovering barite and controlling the density and viscosity of the drilling fluid to make sure the drilling fluid is debris free as much as possible so the drilling fluid can be return back to the rig.

Shearing mixing hopper and jet Mud Mixing System for drilling mud system
Jet mud mixing system is a normal and necessary part of most kind of drilling mud systems and liquid mud plant (LMP). It is used to prepare new mud and qualified mud, and service for drilling activities. The mud mixing system can be used to mix oil based mud (OBM), water based mud (WBM), as well as synthetic based mud (SBM).
Jet mud mixing system is actually a combination of mixing pump, mixing hopper and control panel. All of them connected by pipelines, they can be mounted on the tank separately per tank layout. They can also be mounted on the same skid as a complete unit.
The jet mixing hopper is also called shearing hopper. It can be mounted on different position of the mud cleaning system for different purpose.
Centrifugal pump is the most popular pump model for jet mud mixing system. Another pump model is shearing hopper. Clients can choose motor drive mixing pump, or diesel engine drive mixing pump, to meet for different demands.
Different position of jet mixing hopper for mixing system
1) The jet mixing hopper can be mounted on the top of the mud tank. Advantage of the tank top hopper is easy for mixing chemical as the gravity. But you should to consider lifting of the chemicals. Sometimes, it is even 1 ton big bag. you should consider the necessary device to help for the chemical lifting. Operation table and crane cradle is the popular way to service for it.
2) The normal way is to put the shearing mixing hopper on the tank skid, next to centrifugal mixing pump. The mixing performance may not as good as on the tank top, but also acceptable. And it is easier for the chemical lifting.
3) Another way for the shearing hopper is on a separate skid with centrifugal mixing pump and control system. The complete is in a separate skid. It is more flexible for application. Users is easy to more the mixing unit from one jobsite to another jobsite, or move it from one tank for another.
Trenchless Mud Recycling System of 120 CBM Delivered to Jobsite
Although when talking about the products provided by GN Solids Control, in the oil and gas industry, a lot of people’s first image is the line of high quality decanter centrifuges, but in fact, the traditional products of GN Solids Control is solids control equipment like shale shaker, desander, desilter, shear pumps and shaker screens.

- Oil and gas drilling solids control system including 4 phase of solids control and 5 phase cleaning equipment, the shale shaker, desander cones, desilter cones, decanter centrifuge and the various feeding pumps for those equipment, like centrifugal pumps, submersible slurry pumps, mono pumps and shearing pumps. And also, the vacuum degasser is within GN’s product range.
- Mud cleaning system for HDD projects. The main equipment used for HDD mud recycling systems are similar as the oil and gas solids control systems, especially recently, more and more centrifuges are used for HDD projects after the desilter A slight different is that, in case of oil and gas solids control system, the mud falls directly from the well mouth to the shale shaker, while in HDD project, there is a submersible slurry pump used for transporting the mud from the mud pit to the shale shaker. GN shale shakers are designed differently on the buffer box accordingly.
- Desander plant or slurry plant for Trenchless projects or TBM projects. The mud system or so called desander plant are similar with the HDD projects’ mud recycling systems. And the separation equipment to be used are chosen by clients’ respect. In some cases, the TBM Mud recycling system even use a decanter centrifuge or a dewatering system.

GN Solids Control working for oil drilling field
Recently, we just export one batch of solids control equipment to Middle East. The equipment including some sets shale shaker, some sets mud gun, some sets mud agitator, some sets of centrifugal pump etc. The entire product is going to Middle East for land rig operation mud system.
Except above equipment, GN Solids Control also have other super star equipment to give high efficiency working performance, and with very lower price.
Decanter centrifuge is necessary equipment working for oil drilling mud system. Most of client will need 2 sets centrifuge for operation. The dual centrifuge system including one set high speed centrifuge for lower gravity solids removal; one set lower speed or middle speed centrifuge for high gravity solids removal; screw pump for feeding the dual centrifuge will be also concluded, as well as telescopic high skid for installation.
2) Vertical cuttings dryer
Vertical cuttings dryer is to deal with the waste discharge from shale shaker, recycle the valuable drilling fluids and dry the solids. This vertical dryer is very good use for oil based mud drilling cuttings. The OOC can reduce down to below 5%, much convenient for following transportation or next stage treatment.
3) High G drying shaker
If for water based mud, most of client choose High G drying shaker. The performance of High G drying shaker is not that good as vertical cuttings dryer, but much lower purchase cost and maintenance cost. GNZS594HGE-LD HIGH G drying shaker is used in many different drilling rig site. And the high working efficiency performance and less maintenance give good reputation for GN Solids Control. The shaker screen is replacement for SWACO mongoose shaker, composite material. If the client have GN this model shaker and need shaker screen urgently, the client can buy Mongoose shaker screen to mount it on GN shale shaker.
However, we recommend clients to buy some shaker screen in stock for use in advance. Because the price of original Mongoose shaker screen is much higher cost.
