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.  

GN Solids America, it is the branch company of GN Solids Control Company Limited. It is located in Houston Texas. With its own office building and warehouse.

GN Solids Control and GN Solids America took part in 2015 OTC oil show with great success. The head company GN Solids Control takes its latest design drilling waste management equipment (high speed decanter centrifuge, vertical cuttings dryer) for the show. And GN Solids America show the mud cleaner separator machine for the OTC oil show. Mud cleaner is a 3-in-1 machine, with the function of desander, desilter, and a under flow shale shaker.

GN solids control mud cleaner for oil and gas drilling showing on OTC
1) Mud cleaner model: GNZJ594E-2S12N
It is the combination of under flow shale shaker GNZS594E, a 2-cone desander, and 12-cone desilter.
2) Capacity of the mud cleaner: 240m3/h (max.)
The capacity of mud cleaner depends on the desander cone and desilter cone capacity. The smaller one is the treating capacity of the whole treating capacity.
Desander cone and desilter cone is on D100 separation machine. There will be some amount of useful mud discharged together with dirty mud. So the function of underflow shale shaker is to further treat and recovery mud and dry the solids discharge.
Some jobsite may use desander or desilter with not under flow shale shaker to save cost. But the performance is surely not as good as the combined one.
3) Feeding pipe size of the mud cleaner is 6’’ and the output size if 8’’. GNSB8*6 centrifugal pump is mostly used to feeding for the desander and desilter.
4) Shaker screen of the GNZJ594E-2S12N mud cleaner: the under flow shale shaker is a 4-panel shaker with long shaker deck. It can make the solids more dryer. The shaker screen is pretention type, and mounted with wedge for fast screen changing.
5) GN patent design for Synchronous adjusting of the deck angle. When the operator adjust shaker angle at any side, both sides will be up or down with exactly the same angle. It saves time of jobsite people and easy for operation.

For normal design shale shaker, the clean
fluids discharged from the bottom of shale shaker. Fluids side discharge shale
shaker is a kind of shale shaker that the clean fluids after separation will be
discharged from both side of the shale shaker. It is widely used in many
countries, like Iran, UAE, Nigeria, Brazil, Argentina, etc…

Features of Fluids side discharge shale
shaker

For normal shale shaker, the fluids can only
be discharged to the tank under the shale shaker. Customs should use pump if
they want to transfer mud from shaker tank to other tanks. In case there are
heavy mud settle at the tank bottom, the shaker should be stop for tank
cleaning.

With side discharge shale shaker, the fluids
can be discharged from both side of the shaker deck, jobsite people can use
trough to lead the fluids to other tanks or other place, no need extra pump.

why need Fluids side discharge shale shaker

For example, during well cementation jobs,
operators will inject cement to the rig hole to reinforce the well wall, new
drilling fluids in need in this process, but there are still drilling fluids in
the well hole. With Fluids side discharge shale shaker, fluids from shaker can
be leaded to other place or other systems for treatment, rather than fall down
to the shaker tank.  

Other solids control equipment used together
with Fluids side discharge shale shaker

Desander & Desilter mud cleaner: Shale
shaker is the 1rst stage solids control equipment. After shale shaker, the
fluids will be transfer to desander or desilter separation by centrifugal pump.

Barite recovery decanter centrifuge: it is
the application of middle speed decanter centrifuge to recovery barite from
solids control system, and the recovered barite can be reused in the system.

Jet mud mixing system: it is used to mixing
new drilling mud. And barite recovered from decanter centrifuge also added to
the hopper of jet mud mixer and come to the system again.

Pumps: Different feeding pumps for desander,
desilter and decanter centrifugal, mixing pump, trip pump, charging pump, etc…

Shear pump is a kind of centrifugal pump no need safety valve at outlet. Below is reasons explained from function and pressure source.

Explain on Functions to confirm shear pump no need safety valve

Shear pump is a kind of centrifugal pump. Drilling mud get a certain amount of kinetic energy while leaving impeller under the impeller rotating centrifugal force. Mud also get some certain of pressure in the pump housing, the pressure does not vary with the change of time, pump outlet size, but only depends on impeller structure, size, and rotating speed. As the pressure at shear pump outlet is not vary per pump flow or working condition. It is no need to match safety valve.

Explain on pressure to confirm shear pump no need safety valve

Driving motor and shear pump connected directly with belt. Design speed of impeller is 2200RPM (max.). Under normal working situation, like for 60hz motor, max. speed of shear pump impeller is 1800rpm, much smaller than the design speed. The maximum pressure generated from high speed rotating of impeller centrifugal force is constant. The max. shear pump pressure is 0.47MPa. The outlet pipeline and pump casing can surely withstand the pressure. In this case, it is no need to match safety valve.

Even in the case of the outlet is blacked or the valve is closed, pressure generated from the impeller rotating is larger than pump outlet, drilling mud cannot be discharged, and circulated within pump housing under the rotating force of impeller. If the outlet is blacked or the valve is closed, and mud circulated within the pump housing for a long time, the worst condition is to increase the temperature of pump housing in some degree. The pump pressure will not increase. Therefore, it is no need for mounting safety valve in shear pump outlet pipe.
