desander

GN’s mud system is not only used in oil gas drilling but also in some other drilling projects. Therefore, GN developed the drilling mud recycling system for non-oil drilling like HDD, CBM and water well drilling.
One type of water well drilling is for the drilling water, while the other one type of water well drilling is for water re-injection to underground for keeping the pressure of oil layer for continuous oil producing.
Working principle of the mud recycling system for water well drilling is same as the mud system for oil gas drilling. Removing the cuttings, sand and silt in the drilling fluids to make the drilling fluids reusable is the purpose of the mud recycling system.

Compact Mud System

Shale shaker is always the first stage equipment for solids control; it could remove the coarse cuttings in the drilling fluids. Shale shaker is the only one equipment by separating the solids hundred percent by the size of the particles. The screen could remove out the solid particles larger than the wire mesh openings. By adjusting the G force and the shaker deck angle, the operator could adjust the dryness of the discharged solids.
De-sander and de-silter could be called hydrocyclone unit. Same as the decanter centrifuge, hydrocyclone separates solid and liquid by using centrifugal force. Density difference is the main factor should be considered if the hydrocyclone unit would be applied.
Mud system for water well drilling is designed compact structure. As per the treating capacity, the corresponding equipment with same capacity would be installed in the system. For different drilling depth, the nos. of the mud tanks are various in different mud system.
Not all the shale shaker, de-sander or de-silter would be used in one mud system. GN ever made a mud recycling for a water well drilling project. The main equipment includes shale shaker and de-silter unit, no de-sander involved as the de-silter cyclone could fully hold function of the de-sander unit.
Besides mud recycling system for water well drilling, GN also developed other separation solutions. Any question, please contact with GN freely.

As a drilling mud desander manufacturer, our desander and desilter machinery can be used in separating hydraulic mining slurry into different particle sizes.

Particle size separation machinery:

hydraulic slurry plant

>0.7 mm solids – slurry shale shaker

>0.07mm solids – slurry 10’ desander

>25 microns solids – slurry 4’ desilter

>7 microns solids –slurry centrifuges

>5 microns solids- high speed decanter centrifuge.

Description of Hydraulic Mining Method: The Hillendale Mine hydraulic mining method consists of a series of water monitors which are used to direct a continuous high pressure (up to 40 bar at the Hillendale mine) water jet onto the face to undermine it, thus causing it to collapse. When sand from the face falls in blocks, the water is used to break up the material into a slurry which then gravitates into a satellite pump station situated at an elevation well below the lowest planned mining elevation.

Slurry separation plant

GN Solids control slurry separation plant

GN Drilling Mud Processing equipments and system hold slurry separation plant. Slurry separation plant including shale shaker, desander, desilter, mud cleaner, tanks, etc. GN provides you qualified items insure cost-effective drilling slurry separation with advanced technology.

A multi-stage re-circulating separation plant consisting of inclined vibrating screens to remove the larger solids, desander hydro-cyclones and centrifuges to remove fine material.

Other related slurry separation info

The slurry separation plant utilizes multiple processing steps, each designed to remove successively smaller solids. Critical steps within the process provide solids removal capacities equal to the maximum tunneling rate of the Tunnel boring machine.

A client inquiry us for providing them a  GN Mud cleaner for  MI Swaco 2-12/6T4 Mud Cleaner replacement

GN Mud Cleaner

GN Mud Cleaner

  • Environmentally Efficient – The 2-12/6T4 MUD CLEANER provides efficient removal of sand and silt particles larger than 20 microns, and some as small as 15 microns. Removing and drying drilled solids helps meet environmental regulations by minimizing waste generated and reducing disposal cost.
  • High Performance – Processing capacity of 1,000 gpm with the 2-12 D-SANDER and 900 gpm with the 6T4 D-SILTER concentrates solids onto a classification shaker
  • Versatile – The MUD CLEANER can be operated with the 2-12 D-SANDER, 6T4 D-SILTER or both to process weighted or unweighted fluid systems.
  • Extends Equipment Life – The 2-12/6T4 MUD CLEANER helps minimize maintenance, repair and replacement of downstream equipment.
  • Reduces Operating Cost – The 2-12/6T4 MUD CLEANER reduces sand and silt-size particles and saves liquid, thus reducing mud cost, chances of stuck pipe and lost circulation and improving rate of penetration.
  • Reduces Disposal Cost – The 2-12/6T4 MUD CLEANER minimizes waste generated thus reducing disposal cost.
