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.

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.

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.

Does a HDD mud recycling system need a decanter centrifuge? How to use the decanter centrifuge for HDD?

In most cases, there is no need to use a decanter centrifuge in a HDD mud recycling system. One thing is because the drilling mud for HDD project is not as complicated as the mud for the oil and gas solids control, and even in some oil and gas solids control systems, there is no centrifuge. The second is because that the cost for a decanter centrifuge is high, the centrifuge itself is more expensive than other equipment, and the centrifuge need professional staff to operate it and need more careful maintenance.

But according to the newly established laws and registrations in a lot of countries, the treating result is of higher standard than before, and now it is quite necessary to employ a decanter centrifuge for HDD mud recycling system. Like in China, the leading HDD contractor CPP added into their new mud recycling system a decanter centrifuge.
GNLW452C is a quite suitable model as a HDD decanter centrifuge, it is used after the desilter cones and the middle speed centrifuge is to separate out the particles from 5 to 7 microns. The big bowl design enables GNLW452 to have a large capacity.

If we have an existing HDD mud recycling system, how can we add a GNLW452 into it?

GN has solutions and the design was well tested at jobsite. The GNLW452 could be mounted on a skid and a screw pump and the control panel ( as a VFD control panel) is mounted on skid, below the centrifuge. The screw pump is used to feed the centrifuge from desilter cone. Solids discharge are collected and liquid flows back to desilter tank. This circle also helps to reduce the mud weight.

For more information, welcome to contact GN.

GNMS series mud recycling system is high standard configuration of GN mud recycling systems, they are perfect solution for HDD projects because:

  1. 1. GNZS703E-DZ shale shaker is a mature design of GN Solids Control, it use 3 pcs of shaker screens and the screen area is 2.63 cbm. Same as all the GN Shale Shakers, GNZS703E-DZ shale shaker uses the patented technology for the deck sealing in order to prevent leaking of liquid. Shaker deck frame is Stainless steel to have stronger structure for a longer service life. Unless its peer model GNZS703E-HB which is designed for oil and gas solids control system, this model of shale shaker is suitable for get fed via a submersible slurry pump from a mud pit. It is designed especially for the HDD projects.
  2. GNZS-703E 1S8N mud cleaner is a combination of the 2nd and 3rd separation steps with desander cone and desilter cones, and the shaker below is used as a under shaker for both desander and desilter cones. GN choose polyurethane cyclones as the desander and desilter cones, more wear proof and longer service life than the metal material ones.
  3. As high configuration of GN mud recycling systems, GNMS 500 GL has mixing hopper and mixing pumps for adding new chemicals into the well cleaned drilling mud after recycled. And this 500 GPM system has a larger storage capacity comparing with the standard GNMS 500G system.

HDD is short for Horizontal Directional Drilling, in city constructions, like the laying of pipeline, the water pipes, subway projects and etc, any underground work, there is HDD project. The benefit of this kind of project is, during the drilling, there is no harm to the existing buildings or anything, no need to move any residents or buildings.

Some HDD works are connected with Oil and Gas, because any oil and gas to be explored need to be transported to the conserving place or to the oil companies to be produced into consumable petrol or anything else. Some pipelines are very long, even cross the borders between countries. Some are under sea pipeline. During drilling of such long or wide pipe lines, not only a  professional drilling rig is requested, but also a good performance HDD mud recycling unit

in Australia

to treat the mud.

Because, if the mud after drilling is disposed directly, the mud containing so many cuttings will pollute the soil or water, depending on where you want to dispose it. So it must be treated before discharge to outside. Secondly, it helps to save cost for the drilling procedure. Although most cases, the drilling mud is water based mud, less expensive than the oil and gas drilling, it still costly. After deleting the cuttings from the mud and adding necessary chemicals into it, the drilling mud become possible to be reused.

GN Solids Control is world famous HDD mud recycling unit manufacturer, and has been working in this industry for nearly 10 years. Focusing makes professional, it is very expertise in designing and making it. Now not only for HDD systems, but also for Piling, CBM and TBM, GN Solids Control has standard design to save time for customer and also greatly reduced the cost by large lot of production.

From GN Solids Control, customer could always find good solutions with least money paid.
