GN CBM Drilling Mud System

Character of high G shaker

High G shaker is a kind of shale shaker utilize high G force used in waste management field. It is adapt high G force from 7.5 to 8.0 G.

Upstream equipment of drilling waste of high G shaker

A set of screw conveyor system collect drilling solids separated from shale shaker, desander, desilter and centrifuge,and then transfer and dump to high G shaker for separation.

During this process, clean mud falls into slurry tank under high G shaker, drilling cuttings dump to cutting box and move away by track for further treatment.

Down stream equipment drilling waste of high G shaker

Clean fluids from high G shaker transferred to a waste management high speed centrifuge, fine solids above 2~5 micros will be moved away after centrifuge process.

Swaco mongoose shale shaker is a dual motion shale shaker, adapt composite shale shaker screen.

What is composite shale shaker screen (Swaco Mongoose, GNZS703, ETC):

It is a kind of shaker screen with special mateiral and processing tochnology, it usually has matel inside and rubber outside. 

Advantages of composite shale shaker screen:

Under the same working situation, composite screen have over double lifetime compaired with same model steel screen.

GNZS703 shale shaker is a hot sale model as the replacement of Mongoose shale shaker, they both adapt composite shaker screen.

You can visit GN website for more information of GNZS703 shale shaker and its high quality replacement shaker screen.

Before treating the drilling cuttings by thermal unit, normally, the drilling cuttign will be drying by High G shaker or Vertical Cutting Dryers.

The current thermal treatment product line is based on the Porcupine Processor. This thermal process is designed to treat NADF Drill Cuttings (base oil can be diesel, low toxicity, or synthetic), which reduces the oil on the solids exitthe process to < 1% dry weight, and recovers the valuable base oil in a statesuitable for reuse.

GN Solids Control provides complete line equipment for solids control and drilling cuttings treament.

Cuttings Re-Injection (CRI) is an in situ method for the disposal of drill
cuttings and other drilling wastes into a sub-surface stratum.
Drill cuttings are slurrifi ed with water (fresh or sea water) and ground
down to a pre-determined particle size. The particle size is achieved by
passing through a shaker screen. Slurry of the correct particle size and
physical properties is injected via a pump, which is typically of a triplex
design, into the well head at a given pressure and down into the predetermined

sub-surface injection zone. Oversize particles from the shaker
are re-circulated for further grinding.
Features and Benefi ts:
ƒ Features
ƒ An effi cient method for disposing of NADF drill cuttings
ƒ ARCO licensed slurrifi cation system
ƒ Modular concept
ƒ Venturi feed system

Mud recovery desander and desilter is the 2nd and 3rd stage solids control equipment used for drilling field.

Desander used followed with shale shaker. It usually use 1~3 eah desander cone sizing from 6’’ ~ 20’’ , depends on different applications.Desander can separate solids over 40 micrones.

Desilter used followed with desander. It usually mount 4~20 each desilter cone side from 2~5 inch. But 4’’ mostly used. It can be used to removed solids over 27 micrones.

A big or small shale shaker can be used under desander & desilter, then worked as mud cleaner. It can inscrease the separation performance of the whole machine.
