After the shale shaker and centrifuge separation, the dry solids waste is with little water content, the volume is much smaller than the original waste. And it is easy for transport. And the solids waste can be used as construction material. The recovered liquid phase is with less solids, it can be reused for drilling and mud mixing.

Besides the shale shaker and decanter centrifuge separation, GN Solids Control equipped a small size mixing hopper with a mixing pump to prepare qualified new drilling mud to support a continue diamond drilling and mining activity.

The dirty drilling mud from drilling collar is first collected in a mud storage tank. There is a submersible slurry pump allocated on the storage tank to feed the dirty mud to shale shaker for coarse solids separation. The shale shaker is the 1st stage separation. GNZS752 shale shaker is used in the process. It is a min size shale shaker with single deck and 2 screen panels.

The coarse solids will be screened and discharged from the small shale shaker, the liquid phase will pass the screens and fall down into the #1 sand trap of the mud tank. And then there is a screw pump will suck the liquid from sand trap and feed to high speed decanter centrifuge for fine solids separation.

The replacement screens on the mini size shale shaker GNZS752 is fine in order to remove more solids phase, and to maximum reduce the mud weight. And it is to ensure that, after the shale shaker separation, the recovered liquid phase is qualified for decanter centrifuge separation. After centrifuge separation, the clean liquid will flow to the 2# centrifuge tank.
The mixing pump is capacity to suck the drilling mud from #1 sand trap and #2 centrifuge tank, with the power adding from the mixing hopper, the qualified new drilling mud will be send back to the tank compartment and waiting for sending back to rig via s supercharge pump.

Besides the 9 inch mini size decanter centrifuge, GN Solids Control is capacity to make other big sizes for various application, it includes but not limited to drilling mud solids control system, waste water dewatering system, oil sludge separation system, and drilling waste management system, etc…

A customized drilling mud processing system is is ready for shipment at GN Solids Control Beijing factory. It mud cleaning system is composted of a mud cleaner, a mixing hopper, and a centrifugal pump for mud mixing and transfer.
The drilling mud cleaning and mixing system is designed and made by client’s request to suit his drilling mud situation. Normally, mud cleaner is equipped after a pre-seperation shale shaker. But in this mud cleaning system, the first separation equipment is mud cleaner.

Drilling Mud Cleaner

The reason why the client do not use shale shaker is that, they said the solids content in the mud is not much high. And mostly are fine solids. In this case, the drilling mud can be separated by mud cleaner directly. It is to save cost. As once the shale shaker is running, clients need to replace shaker screen periodically. It is a continue cost for operation. While delete the shale shaker, the system can meet client’s request. It can save the cost of shale shaker, and furthermore, the can reduce wearing spare parts shaker screen cost.

But if the solids content is high, or the particle side is big, which is over the hydracyclone separation point and its mud handing capacity, it is better to use a shale shaker before the mud cleaner. At one hand, the shale shaker can reduce the flow rate which feed to the mud cleaner. At another hand, after the shale shaker separation, the solids content will be reduced, and the big size particle are total removed based on the shaker screen API size and cut point. It can increase the hydraucyclone separation efficient, and also to avoid the fast wear out the hydraucyclones. 10 inch desander cone and 4 inch desilter cone are the most popular cyclone sizes used for drilling fluids separation system. Operator can choose the to use only desander cone or desilter cone, or both based on the mud condition and their budgetary. Desander and / or desilter cone quality depends on the handling capacity of the whole system.

Drilling Mud Centrifuge

Feeding pump for mud cleaner is centrifugal pump. The centrifugal feed pump is located on tank slope for compact design and for maximize the total tank usable volume.

After the mud recycling and mixing system, a drilling mud decanter centrifuge is used for fine solids separation. As there will be more and more fine and ultra fine solids after some circulation of the system. Decanter centrifuge will be used to reduce the mud weight.

500GPM and 1000GPM are the most popular size drilling rig mud recycling system for Horizontal directional drilling, water well drilling, Coal bed methane drilling, and other trenchless drilling rigs.
500GPM mud recycling system is mostly a compact 1-tank system complete with separation equipment and mixing unit for compact design and easy movement.

Regarding 1000GPM mud system system, clients can choose 1-tank system or 2-tank system. 3-shaker mud recycling system and 4-shaker mud recycling system are the most popular proposal. 3-shake mud recycling system means 2 shale shakers plus a mud cleaner (3-1 mud cleaner, desander mud cleaner, or desilter mud cleaner).

Equipment list for 1000GPM mud system is normally as below:

1) At least 2 sets shale shaker. 4-panel or 3-panel shale shaker model are both fine. Single shale shaker model is min. 500GPM capacity. So for 2 shale shakers the handling capacity can reach to 1000GPM minimize.

2) 1 set of mud cleaner c/w shale shaker, desander and desilter, mud capacity is at least 1000GPM. It is the full functional and with compact design. As a 3-1 mud cleaner can save footprint. If clients want to reach a better separation performance, they can also choose a separate desander mud cleaner, or a desilter mud cleaner. Regarding the desander mud cleaner and desilter mud cleaner, clients can choose to equip with the same under flow shale shaker as the first stage shale shaker, or a mini size shale shaker with 2 screen panels. Clients can also choose a small desander or desander without shale shaker.

3) Feeding centrifugal pump for mud cleaner is 45kw or 55kw. The feeding pump can be located on tank skid or tank slope.

4) Mixing unit is C/W 6 inch mixing hopper. Mixing pump can be 45kw or 55kw. It is better to be the same model with mud cleaner feeding pump.

For 3-shaker system, all separation equipment and the mixing unit can be located on the same mud tank for company design. But if it is 4-shaker mud system, the first tank is recycling tank with separation equipment, the next tank is mixing tank.

GN Solids Control is focusing on the full package of drilling mud processing system. As GN Solids Control makes full line drilling mud processing equipment. They know well about the equipment. GN Solids Control can offer professional proposal of drilling mud treatment system and mud mixing unit. All processing equipment and the tank volume should be match to each other.

For example, if the total shale capacity is max. 160m3/4 or 200m3/h, but the desilter and desilter capacity is 240m3/h. And feeding centrifugal pump and mixing pump are 55kw or above. The system is not reasonable. As the 1rst stage separation equipment, the shale shaker capacity should be bigger than the next step separation equipment. Otherwise, if the mud flow is big, the shale shaker will overflow. Or if the mud flow is small for the shale shaker to handle, but the desander and desilter pump are too big, it will cause pump suction air. And the hydrocyclone separation performance is not good in condition the feed flow is too small. The client need to increase shale shaker capacity, or decrease pump and mud cleaner capacity to suit for the mud pump capacity.

Every jobsite is different. Every client has his preferable. In order to offer a suitable mud system design to suit for the job site situation, as well as client’s special requirements. Below are some questions to let GN Solids Control knows more about clients request.

1) what is the rig horse power of the system for, or what is the mud pump horse power or capacity? The whole mud system handle capacity should suit to the mud pump capacity.
2) What is the total tank volume the client prefer?
3) How many tanks the client prefer?
4) What is the max. Tank size (L × W × H) the client can accept to suit for their local shipping regulations?
5) What processing equipment they prefer to equip inside the system? Shale shaker, mud cleaner, desilter, desilter, mud cleaner, vacuum degasser, decanter centrifuge, etc..Which processing equipment they want?
6) What is the Voltage and hz for the mud system?
7) What is the explosion proof standard, CNEX, ATEX, or international IECEx standard?
8) Additional requirement and any special requirements if there, like do they want trip tank, pill tank, water tank, etc…
