cuttings

China traditional new year will come in Feb. 2016. In order to thanks all GN clients’ support in the past year, GN Solids Control offered big discount for sale for GN drilling waste management equipment. The big discount for sale activity will last for the whole Jan.
Drilling waste equipment GN company offer big discount for sale in Jan. 2016:
1) Vertical cuttings dryer GNCD930C and GNCD930C-VFD. It is mainly used to treat the oil based drilling cuttings (OBM). Performance is very good. The Vertical cuttings dryer can reduce the oil on cuttings to 3% ~ 5%. After VG dryer, the solid discharged is very dry. It is easy for movement by truck. In some countries, it can be discharged directly with such low OOC. If not, it can be removed to treat by thermal desorption unit. 

2) High G dryer (also called high G drying shaker). It utilizes high G force reach to 8.0G to dryer the cuttings. High G drying shaker is mainly used to separate water base mud cuttings. Water base mud is more difficult for separation. The main problem to treat WBM with VG dryer is that, the mud will block the screen basket, then it cannot separate any mud any more. High G dryer shaker can also be used to treat oil base mud. But it can only reduce oil on cuttings to 10 ~ 15%, it is not enough.
3) High speed decanter centrifuge GNLW363C and GNLW363C-VFD. It is 14 inch decanter centrifuge. 14’’ is the most popular size centrifuge used in oil and gas drilling field. Client can choose fixed speed control or variable frequency control. For the VFD control, GN offers PLC touch screen for smart control.
4) Big bowl decanter centrifuge GNLW553C-VFD. It is a big bowl big volume decanter centrifuge. It is with a 22 inch bowl. It is the biggest size from GN Solids Control. It can be used for waste management, for mud solids control, as well as chemical dosing system (dewatering unit).
5) Screw conveyer. GN offers different diameter and different length screw conveyer for drilling cuttings transfer. The auger diameter do GN Solids Control offer: 10’’, 12’’, 14’’, 16’’, and 18’’. GN make 12 ft as standard design for each section. Clients can choose 1 ~ 4 sections for 12 ft, 24 ft, 36 ft, and 48 ft. Clients can reduce or extend the length at jobsite when need.

Oilfield screen shaker separator normally called oilfield shale shaker or screen separator. It is the first step solids control equipment used in oil field and other drilling activities. It is the necessary solids control equipment for mud systems, no matter for oil and gas drilling, HDD, CBM, TBM, or piling.

Per the motion type of screen shaker separator, there are linear motion screen shaker separator and balance elliptical motion screen shaker separator.  
Oilfield screen shaker separator is normally linear motion type. And linear motion screen shaker separator is the most popular and long history type. Linear motion is more reliable. It can suits more kinds of jobsite condition.
While Balance elliptical screen shaker separator is very limited with jobsite and mud condition. When there are big load of mud, or the mud fall onto screen shaker deck unequally, the motion will be damaged and the BEM shaker cannot be working well. Mud will be over flow.

Per shaker deck quantity, there are single deck screen shaker separator and double deck screen shaker separator. Double deck screen shaker separator can be used for scalping shaker separator. The top deck use coarse mesh screen for pre-separation, while the bottom deck use normal mesh wire screen per jobsite condition.

Per the difference of applications and G force, screen shaker separator can be divided into solids control screen shaker separator and drilling waste management high G screen shaker separator. Beside the application G force is different, for solids control screen shaker separator and drilling waste high G force screen shaker separator, the feeding type of the 2 screen shaker separator is also different.
Solids control screen shaker separator is normally use top type or back type weir feeder, or box feeder, while drilling waste screen shaker separator is use hopper feeding.
Solids Control screen shaker separator can be fed by slurry pump or fed directly from the rig manifold under gravity. While drilling waste screen shaker separator can be fed by screw conveyer or cuttings transfer pump.  

High G drying shaker, also named high G dryer, it is a kind of shale shaker utilize high G force to reduce the water contend in water based drilling cuttings.

Applications of High G drying shaker for water base mud

Unlike solids control shale shaker, high G drying shaker is used to treat drilling cuttings comes from solids control shale shaker, desander or desilter. There is noamally 4-panel shaker screens for high G drying shaker. More shaker screen enable a longer route of mud going through the screen machine.

High G shale shaker cannot be used in solids control system directly. The high G force will destroy the mud contend of the drilling fluids. If it is really need to use high G shale shaker in solids control system, the G force should be reduced.

High G drying shaker is used to treat water base mud drilling cuttings, while vertical cuttings dryer used to treat oil base mud drilling cuttings.

Features of GN brand high G drying shaker

GNZS594HGE-LD is a typical model high G drying shaker. It is a 4-panel shaker utilizing composite material shaker screen 1165×585mm. It is common side shaker screen easy to be interchangeable with other brand shakers.    

Unlike other brand, GN brand high G drying shaker utilizing stainless steel material for shaker deck for long lifetime.

Synchronous shaker deck angle adjustment device. It is GN patent design. Both the shaker deck angle can be changed equally when you adjust from either side.

Other equipment used together with high G drying shale shaker

When drilling cuttings discharged from solids control shale shaker, desander and desilter, a screw conveyer will be used to transfer the cuttings and feed to high G drying shaker. After high G drying shaker, the clean fluids will be transferred to high speed decanter centrifuge to separate the fine solids inside.

If there are high content fine solids over centrifuge separation scope, dewater unit should be used.

A customer contact GN with their inquire that, they want to carry out the reclamation (Treatment and disposal) of the drilling cutting waste which collected and storage in the lined pit by utilizing the routine process as well as this process shall be proceeded when the drilling operation is finalized and the rig moved to other location. Therefore, by researching and studying, they have find out new methodology of treatment and disposal these waste by new technology that was utilized in various global oil and gas industries, instead of the old treatment and disposal process.  

The customer would like to get and utilize this Drilling waste management unit for carrying out the treatment and disposal process of the collected drilling cutting waste in the lined pit. They want to know, if there is available alternative equipment (Unit) in our firm or if GN-Solid Control  Company can provide such equipment (Unit).
