Last week, another landmark of GN Solids Control was achieved, that GN started the construction of new office building which located in Yutian New Factory.


Yutian is also located in Hebei Province and it is not far from the existing 2 factories GN owns now. GN Solids Control chose it as the location of GN’s 3rd factory to enable the company to reach a new level with most advanced producing facilities.
Precisely spoken, it should be GN Solids Control’s 4th factory ever since its establish in year 2007 in Tangshan City of Hebei. At first, just like all other private owned companies, it was not so big, having only a small yard for fabrication and 2 offices. But even though, GN Solids Control had set eyes on the international standards, and has devoted itself to making the high quality equipment to meet the international markets.
Five years later, in year 2012, GN moved from the old factory to where its headquarter location now. And from year 2007 to year 2012, GN has become the 1st API Certified solids control company in China and developed its first vertical cuttings dryer.
In year 2015, GN started the 2nd factory in the same industry zone as the headquarter, and expended the production ability by starting a separate workshop for rotating equipment like decanter centrifuge, vertical cuttings dryer and centrifugal pumps, and also another workshop with welding and cuttings robots for shaker screens.
Now the 3rd factory is under built and the area of the 3rd factory is even bigger than the 2’s sum-up. In the 3rd factory, GN will have all the workshops to be developed into a new level and a most advanced painting line added.
A new start, a new level, GN will make it.

Recently, GN has delivered a batch of shale shakers to an international drilling company. Those shale shakers are especially designed with dual motional function to be adapted to different drilling stages.
In the shale shaker market, the most popular 2 shaker motions are linear motion and elliptical motion. Each of those has its own characters:

  1. Linear motional shakers: such shakers have larger G force and large conductance, with bigger treating capacity. Those shakers can give a direct force on cuttings. Cuttings won’t stay on screen for long. In a word, the linear motional shakers are suitable for drilling mud with low viscosity, large capacity, large solids content, containing big and hard particles.
  2. Elliptical motional shakers: those shakers are softer to the cuttings, and cuttings will stay on screens for a comparably longer time. Screen holes are unlikely to be blocked. Cuttings are more likely to stay unbroken during working. Those shakers are more suitable for mud with high viscosity, low capacity, high solids content and easy to be broken.
    In practical at the first and second stages during drilling work, the operators prefer a linear motional shaker, while in the third and fourth stages, the operators would like to use an elliptical motional shaker because of different mud condition and land constitutions.
    GN dual motional shale shaker could be used for both conditions by shifting from one motional mode into another. In this way, even for deep well drilling projects with drilling mud to be changed from WBM to OBM, the operators could get the satisfactory performance without changing to another set of shakers. Besides the dual motional shakers, GN also has linear motional shakers with 2 or 3 or 4 pcs of shaker screens.
    Shaker screens are also one of the core products GN could provide. For more information, welcome to contact GN freely.

Middle East is a mysterious and special place in the world, which contains the largest crude oil reservation. The importance of crude oil in modern industries brought Middle East countries wealth and high welfare. Like Dubai, it has developed from a desert port into one of financial centers of the world.
For the equipment related to the oil drilling and oil services, middle east companies only focus on the best quality ones. In field of oil and gas drilling solids control and drilling fluids separation, GN Solids Control is the 1st Chinese brand accepted by this market and also the No. 1 from China. Just recently, GN Solids Control just delivered a batch of equipment including following:

  1. vacuum degassers. Before the drilling fluids being treated by the desander and desilter cones, it still has lots of gas in it. This gas would reduce the efficiency of the centrifugal pump, and also cause some damage to the pump. A vacuum degasser could remove the gas from the drilling fluids, and unless the degasser from US or European manufacturers, GN Vacuum degasser is in no need of a large power pump. Meanwhile, it also services as a big agitator.
  2. Mud cleaners. Mud cleaner is a combination of desander cones, desilter cones and a underflow drying shaker. 2 centrifugal pumps are used for feeding for desander and desilter cones, the 10 inch desander cones are used for separating out particles larger than 40 microns, and 4 inch desilter cones are used for separating out particles larger than 20 microns. The solids discharged from cones fall onto the underflow shaker for drying.
  3. Centrifugal pumps are also one of GN’s core products. GN has full range of centrifugal pump models for solids control applications. All spare parts are interchangeable with Mission Magnum pumps, and pump impeller and casing are made of hard alloy.
    Welcome to contact GN for more information.

As the professional turn-key solution provider, GN Solids Control has provided mud recycling system and slurry separation system to many different applications including oil and gas solids control, drilling mud waste management, oily sludge separation, HDD, CBM and TBM.
All drilling or boring works are based on similar working procedure, as they all use a media for drilling, which is called drilling mud. And when the mud is out, it brings out a lot of drilling cuttings like sand and soil. An efficient mud separation unit can help to remove the cuttings to the most and save as much as drilling mud for future reuse. In order to achieve good goal for different applications, GN has designed and applied to different industries.

  1. For piling: for the piling works in cities, GN Solids Control has a series of compact desanding units for option. Those desanding unit are mainly equipped with a double deck shaker, with 2 steps separation: a lower deck shaker and a desander or desilter. And the optional capacities are 200GPM, 350GPM, 500GPM and 1000GPM. With a catch tank on below, it can be used continuously at piling site.
  2. For HDD: for the horizontal directional drillings, which are mostly for the pipeline laying work, GN has provided to market self-contained mud recycling units, fitted with shake shaker, desander and/or desilter and mud mixing unit and mud tanks with necessary storage volume.
  3. For TBM. For the big TBM projects, normally they need 3 steps separation: the shale shaker, desander cones and desilter cones. Recently, GN Solids Control designed a series of quite suitable system for such TBM projects, and before the shaker, for choosing out the big rocks and particles, GN designed a coarse shaker before the normal shakers, and in layout, it is quite compact for both transportation and operation.

What is a solidification unit? As its name, a solidification unit’s function is to reduce the moisture of some material, to get it dryer, or change it from liquid to solid. A GN Solidification unit is designed originally for the final treatment of drilling cuttings discharged from the vertical cuttings dryers and decanter centrifuges which are used for drilling cuttings separation.
Normally, the OBM drilling cuttings from a drilling cuttings vertical cuttings dryer is already quite dry, with oil on cutting only 0.5%. But still, it is not clean enough to be disposed, cause the cuttings then are still a little bit wet and with lots of active agent in it. A solidification unit’s function is to get the active agent into inactive, in order to allow the cuttings to be safely disposed. GN Solids Control has put the solidification unit into market for several years, and has sold it to both inside China and abroad.
GN Solidification Unit has following features:

  1. GN Solidification Unit is suitable for both oil based mud and water based mud cuttings.
  2. GN Solidification unit is easily operated by VFD controlled, easily to adjust the input capacity and chemical usage capacity.
  3. GN Solidification unit could work automatically and continuously.
  4. By using the solidification unit, the cuttings could be buried directly in most of jobsite, or being made into bricks for roads.
  5. Comparing with other solutions, the solidification unit is less expensive.
    Talking about other solutions, GN Solids Control, as a professional separation solution provider, has other solutions available, for example, the thermal desorption unit. And all above mentioned equipment used for such separation, as the shale shaker, mud cleaner, and solids control decanter centrifuge, and in a waste management system, for both cuttings treatment and fluids, there are vertical cuttings dryer, chemical dosing, oil water separation and inclined clarifier.
