The negative affect from the oil crash has spread to many industries related including the HDD projects. But as the leading and well known HDD mud system manufacturer, GN Solids Control still have orders and repeated orders from the old clients.
By end of last year, GN Solids Control has just delivered a high configuration of mud systems for a HDD project. Now the end user is laying a repeated order for the same mud system, and it is scheduled to be ready early after Chinese New Year.
Not only for the oversea market, but in domestic China, 500GPM mud recycling system is still the most popular option for HDD projects. CPP, the largest HDD contract in China, purchase around 10 sets of mud recycling systems from GN Solids Control each year, and most of those are of 500GPM capacity.

500GPM Mud System

Main Equipments for Standard Configuration GNMS 500 Mud System:
Shale shaker: GNZS703E-DZ, 1 set
Mud Cleaner: GNZJ703E-D1S8N, 1 set
Mud Cleaner Feeding Pump: GNSB6*5A-37KW, 2 sets, used respectively for desander cones and desilter cones
Mixing Hopper: GNSLS35A, 1 set
Mixing Pump: GNSB6*5A-37KW, 1 set, same specification as mud cleaner feeding pump.
Mud Agitator: GNJBQ 075D, single layer impeller with 7.5KW motor, 1 set
Mud Gun: GNNJQ50A, 2 inch mud gun, 1 set

Besides this standard configuration of mud recycling system, GN also has GNMS-500GL mud recycling system, the main equipment for treating are exactly same, but the storage capacity of GNMS-500GL is larger.
And for HDD mud recycling systems, GN has other treating capacity solutions for option, like 200GPM and 1000 GPM.
In case of piling or so called TBM projects, there are simpler solutions for option. Because for piling projects, the drilling media is mostly water, there is no need to add more chemicals into it, and the treating result is not so strict.

Because of the special characters of HDD drilling projects, many end users, the HDD drilling operators prefer a portable mud recycling system to be movable from one jobsite to another easily. In order to better serve the need of clients, GN Solids Control has designed and put into practice some solutions per different jobsites condition.

What mud units does GN Solids Control have available?

GN standard designs of mud system could be divided into 2 catalogues:

  1. premium configuration of mud systems, which is suitable for applications including trenchless HDD drillings, CBM drilling or geothermal well drilling, TBM drilling and Bored piling and also water well drilling works. In the higher configuration systems, there are normally 3 steps for separation, including the shale shaker, desander of 10 inch hydrocyclones, and desilter of 4 inch hydrocyclones and a mud mixing system for adding new material into the drilling mud. Because of the function and efficiency of such mud systems, these systems are also called self contained mud recycling system.
  2. economic configuration systems for mud recycling are always used for bored pile drilling, micron TBM, some HDD drilling or small capacity or lower standard, water well drilling and some mining drillings. These mud recycling systems are also called desander plant, because they have 2 steps of separations, the shale shaker and desander cones. In GN’s design, they always us a double deck shaker, the lower deck shaker plays as shale shaker, the upper deck shaker is the drying shaker of desander cones.

1500 GPM Drilling Mud Recycling System

We can see clearly, the two kinds of mud systems serve similar applications, in fact, in practices, the end users are different when choosing their solutions. Some systems are more likely somehow customized. For both configurations of mud recycling units, GN has 200 GPM, 350 GPM, 500 GPM and 1000GPM available.

In order to serve the portable requests of end users, GN also designed for hydraulic hoisting systems used for Australia market, the containerized corner of mud recycling systems used in Singapore, and trailer mounted systems used for middle east and Africa.

Mud Mixing & recycling unit is indispensable in almost all of trenchless applications.From HDD, to Microtunneling and pipe jacking.GN Solids Control is a professional manufacture for drilling mud recycling unit.GN’s Mud mixing & Recycling system is widely used for HDD, CBM drilling, Pipe jacking, etc. GN mud recycling system can effectively recirculating drilling fluids ,remove solids, and mixing and blending additives into water and deliver it to the drill rig to be pumped downhole.

Basic Components of  Mud Mixing & recycling units consist of: mud tanks, separated into compartments; one or more shale shaker,desander,desilter and centrifugal pump,hopper, mixing pump, mud agitator,etc. an efficient recycling system must mix,clean,recirculate and pump fluids to the drill rig all at the same time.

Removing solids is done in stages. Depending on screen size, first stage using shale shaker removes solids larger than about 250 microns in size. Second stage using desanding hydrocyclones with underflow shaker combinations to remove solids down to about 100 microns, Third stage using 4-inch desilter hydrocyclone can remove solids as small as 10 to 15 microns .Mud Recycling units usually are rated by the gallons per minute a system can pump and clean. GN Solids Control is an professional Solids Control Equipments manufacturer in China. we can offer mud recycling unit which  available in a broad range of sizes with ratings from 50 gpm to as high as 1,000 and 1,500 gpm.

Drilling fluid, also called drilling mud, is a fluid used for lubricating drill rigs, cooling drill bits and carrying off chippings while drilling.

Drilling fluid is widely used in fields like: oil & gas drilling, HDD, CSG, water well drilling, workover, etc.…

The three main categories of drilling fluids are water-based muds (which can be dispersed and non-dispersed), non-aqueous muds, usually called oil-based mud, and gaseous drilling fluid, in which a wide range of gases can be used.

The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage and to limit corrosion.

Drilling fluid is an expensive apparatus for drilling works. Reach an effective recycling of drilling fluid can save the drilling cost greatly.GN Solids Control can manufacture and supply whole line solids control equioments with high quality.
