In order to help preventing the drilling cuttings from polluting the land and water, and also to match the clients’ requests to minimum the cost, GN has successfully designed and manufactured several solutions of waste management systems for safely and economically discharge the drilling cuttings, and those designs have won the acceptances and good feedbacks from the clients.


Per different conditions, GN has designed 2 optional standard solutions:

  1. GNDC40A. it combines the vertical cuttings dryer GNCD930 and high speed decanter centrifuge GNLW363CG, or GNLW363CG-VFD, it fits for both OBM and WBM drilling cuttings. It has a compact structure but there is no storage tank for receiving the clean drilling fluids from the centrifuge. Because this design is suitable for being used alongside the drilling rig, the liquid goes directly from the high positioned centrifuge to the solids control’s storage tank.
  2. GNCD40B is another standard solution for the complete drilling cuttings waste management systems. If the equipment is disassembled from the tanks, the whole system could be transported in a container and easily shipped by sea. Comparing with GNDC40A, this 40B system has a larger storage tank and always used for treating the drilling cuttings separately from the drilling rig jobsite.


If per your jobsite layout or requested functions, they are not so satisfying for you, you could choose GN waste management modules, including GNZS594HGE-LD drying shaker, GNCD930 vertical cuttings dryer and GNLW363CG-VFD decanter centrifuge, and several equipments for optional for transporting the drilling cuttings including the screw conveyor, the submersible slurry pump, the vacuum pump or the diagram pump. In this way, you can choose your own equipments and position them at any place for your project. During the procedure, you can easily choose to stop or start any of them.

In early this year, GN has delivered a slurry unit to a well know middle east company which has business and projects covering many sections of oil and gas industry, including the construction and pipeline laying projects, and also the refinery of oil.
In most persons’ mind, the best equipments and most advanced equipments are from USA or European companies. But GN Solids Control has changed their mind with good quality equipments and reliable service. This is the first time this company chooses a Chinese supplier, before that, they purchase only from USA, like the Vermeer rigs and Derrick shakers.
The first deal with GN is like a trial deal. The operation manager say, it is their first time to use a desanding plant, and it is also the first time they buy from China. If this mud system works well, the second order will come soon.
GN Solids Control didn’t fail in satisfying the clients, within the first 10 days of working on jobsite, the middle east client sent the second order, of the same desanding plant from GN. And this mud system for the second order, was delivered to the loading port last week and soon, within 30 days, it will arrive to the new owner.
mud system
More information about this slurry system:
1. treating capacity: 1000GPM
2. equipments contained in the slurry unit: double deck shale shaker with 2 sets of 10 inch diameter desander cones, the lower deck shaker is first separation procedure and the desander cones are the second procedure, while the upper deck shaker plays as a drying shaker for the ones, with finer screens than the lower deck. Slurry pump or centrifugal pump for feeding the desander cones.
3. compact design, with a dimension suitable for transportation in a 40ft container.
Besides the economic solutions with only separating equipments, GN also have high configuration solutions more suitable for big capacity HDD projects.

For oil and gas drilling work in many jobsites, especially for deep oil and gas wells, there are many different material and chemicals or other additions used during work. Some cheap ones could be discharged or re-treated if they are harm for environment. While some expensive materials should be recovered for future re-use. Barite is one of them. So the barite recovery centrifuge is an important equipment.

GNLW452 Decanter centrifuge is an ideal choice for this application, in all the solids control systems GN made, most of them use this model GNLW452 for the barite recovery and it was proved efficient.

Main Specifications of GNLW452 Decanter Centrifuge:

Bowl diameter: 18 inch or 450mm

Bowl length: 43 inch or 1105mm

Effective capacity: 176 GPM

Max capacity: 250GPM

Max bowl speed: 1800RPM.

G Force: 815

Gear box torch: 57:1


GNLW452 Decanter Centriufge, big bowl large capacity

GNLW452 Decanter Centrifuge is designed to be a middle speed centrifuge, in order to separate the low gravity material like the barite recovery, in some jobsites, per customer feedback, GNLW452 is even having better performance than the US made and European brands.

What features does GNLW452 have?

  1. For this model, GN has improved it to the 3rd generation, with a lot of improvements, with better solids discharge and effectively avoids the blocking of material.
  2. Instead of spray welding on the impeller, GN use special ceramic tiles to ensure a easier future maintenance without re-adjusting the dynamic balancing and enables a longer service life.
  3. World famous brand bearings to get a stable performance and a longer service life.
  4. Patent solution for bearing protection during transportation which greatly helps to prevent damage to bearings.
  5. Big bowl, 18 inch bowl diameter to have a large capacity.

Other options for the GNLW452C decanter centrifuge.

The standard GNLW452C decanter centrifuge is a fixed speeded one, but for the same model, we also have VFD available. In some high standard HDD mud recycling units, end users prefer this centrifuge in VFD control panel after the hydrocyclones for further treatment.
