Drilling waste management is one of the core system GN Solids Control produces, it includes the drilling cuttings separation and also the drilling fluids separation. Dewatering unit, which is also called chemical dosing unit is one of the important components of the drilling fluid treatment systems.

In some countries and regions, it is a must that a drilling rig must be accompanied with a dewatering unit and a dewatering centrifuge, for one thing, more drilling mud could be recycled, which means to reduce the cost and save money. For another thing, it is reducing the harmful components to be discharged to the soil or environment, it helps to protect the surroundings.

GN Solids Control has been providing the dewatering unit for many years, and the dewatering unit now are more and more widely used for different applications, such as:

1. Oil and gas drilling fluids separation. After being used for a certain time, there are more and more extra fine particles in the drilling fluids, even too fine to be separated out by a centrifuge. By adding some chemicals into the fluid, the extra fine particles flocculate into bigger ones to be separated out by centrifuge.

2. In TBM, Piling and other projects, when the slurry is of higher viscosity or need to be added with some chemicals, the dewatering unit is playing an important role, just as shown in the picture, the treatment was successful.

3. In oily sludge separation projects, the added chemicals helps to separate the oil from the cuttings, which greatly increase the efficiency of centrifuge and oil water separator.

GNLW Series decanter centrifuge, especially GNLW363G-VFD, GNLW553-VFD centrifuges are always ideal choice for working together with dewatering unit. Besides those models, GN also has centrifuges with bigger length-diameter ratio for clearer separation.

GN Solids Control is a famous brand who started from solids control equipment manufacturing, and now also professional in separation solution provider in nearly all fields including the oil gas drilling projects, HDD projects, TBM works, piling, water well drilling, drilling cuttings treatment, drilling fluids treatment and other industrial separation works.

GN EQUIPMENT WORKING VIDEOS
But still, among all the applications GN Solids Control’s products are used for, the traditional solids control system and equipment still occupies a large ratio among all GN’s products of each year, especially for the high standard clients, GN Solids Control is still their favorite and reliable supplier. For example, the Asian and Parcific market, like in Australia, New Zealand and India, where their standards are even higher than the USA and Europe.
In Australia, there are some special and difficult to reach standards, including the electric cable connections and layout, the tank surface treatment, the material choosing and even stair positioning. But GN Solids Control has rich experiences in working with Australia and New Zealand and also is well known by those clients. That’s why, during the past years, GN Solids Control has sold to Australia more than 30 sets of mud systems, not including the single equipment like decanter centrifuges and vertical cuttings dryers.

GN RECENT PROJECT NEWS
India is also a special market, India has talent management team and also brilliant engineers, they set up a high standard for their equipment, especially in oil and gas industries. For example, the shale shaker material, they always request the stainless steel as the material of the shaker frame. Although there are local solids control manufacturers in local India, still, clients are coming to GN for the suitable models and solutions. Even in Middle East, the management from big Middle East countries who are Indians prefer to choose GN Solids Control as manufacturer.

This is the first order that company signed with GN, the chef engineer from the client say that this slurry plant is a test and beginning, if it is suitable for their projects, new orders will come soon, not only for slurry plant used for piling, but also HDD mud recycling systems.
In fact HDD is one of the 3 main majors, which include:

1 Drilling Waste Management Systems for oil and gas,

2 Oil and Gas Solids Control system and equipments,

3 HDD mud recycling systems and mud unit for TBM and piling and etc.

 

For such systems like mud recycling systems and slurry plants, GN Solids Control has following benefits:

1. GN Solids Control is most professional manufacturer for Solids Control Systems and Mud recycling systems, as is recognized by many end users in this field. For example, CPP, China Petroleum Pipeline, choose GN Solids Control as a long term and stable supplier for HDD mud recycling systems.

2. Australian market is regarded as the most difficult market in the world to enter, with the world’s highest standard. GN Solids Control is the only China manufacturer whose systems entered Australian market, cause GN’s systems are not only certified by API, ISO, but also DNV CE, and also some certificate from Russia.

3. Many world famous HDD Rig companies like Vermeer, use GN Solids Control’s systems into their packages and using them in jobsites.

 

May you need any such systems or have any question about it, pls don’t hesitate, just call us or send us email, we’re glad to help you find most suitable solution for your projects.

Urban tunneling is one kind of TBM projects. When we mention the TBM, Tunnel Boring Machine, one must think of some in-city constructions like the subway, cross-mountain tunnel and etc. Exactly correct! In history of TBM, the tunnel diameter can range from as small as I meter by micro-TBM, to as large as 19.25 meters.

In TBM projects, there is special requirement that the surface of the working ground is better not disturbed or damaged. In this condition, the operator must pay enough attention to keep the soil pressures during and after construction of the tunnels. And also, pre-planning is vital to these projects, existing pipelines, and existing infrastructures must be taken into consideration.

GN has various optional capacity of mud systems

Just as all the drilling related to, no matter it is hard rock TBM or soft ground TBM, there must be a drilling mud cleaning system related to. Depends on the various capacity requirements, TBM mud recycling systems varies.

GN Solids Control is top manufacturer in China and also wellknown manufacturer in the world for mud systems for oil and gas drilling, TBM, HDD, PILING and etc. Lots of HDD companies, like CPP in China, HDD Rig manufacturers like Vermeer, TBM contractors and Piling contractors stably order their mud systems from GN Solids Control. CPP, for instance, purchases from GN around 10 sets for systems each year.

In order to provide with customers more suitable and quick mud recycling solutions, GN has standard configuration designs for different typical capacities at hand. In this way, a customer can easily choose what is needed, save time for customers. Sometimes, GN even has in-stock systems for customers’ convenience.

GN Solids Control is the first API certified solids control manufacturer in China, and also an ISO certified company. It got HSE certificates last year and its solids control systems has got CE Mark by DNV. It has exported systems and equipments to Russia and has got TP &TC certificate to Russian market.

Besides Oil&Gas drilling, HDD and Piling are both important drilling works, which of course need drilling mud recycling systems. Although all drilling mud systems shares same principals, they have different characters per the different standards of mud.

  1. Finer screens for HDD than Piling

In piling projects, the requirements of fineness of drilling mud are not so high. So the shaker screens used in mud recycling system for piling is not as fine as is used in HDD. Usually grating screens are ok in piling projects, while in HDD, shaker screens are similar with Oil & Gas drilling.

  1. More further treatment for HDD than Piling

In most cases, desander as last treatment for Piling drilling mud is OK. After treated by desander cyclones, the drilling mud can be returned to the system. But for HDD drilling, there is always desilter cyclones adopted.

  1. Larger storage capacity for HDD than Piling

  2. Some cases, mixing hopper is necessary in HDD drilling projects

 

GN Solids Control is famous brand for designing and manufacturing closed loop mud recycling system for oil & gas drilling, HDD drilling and Piling. For HDD mud systems, lots of customers all over world use GN Mud recycling system in their drilling package with Ditch Witch or Vermeer drilling machines. Also, as simple configuration, GN Solids Control has very cost-effective GND series mud system for Piling and Micro Tunnel.
