If you have over 30 years experience for drilling, you will know, what is real required and what is not for close loop mud system. Sometimes people just seek for unrealistic specifications, which did not mean good for the operation. GN solids control would like to share your new idea about the drilling solids control, and put your idea into realization. We have the ability to design as your layout, no matter you choose us as the complete system manufacturer or not.
 close loop mud system Recently drilling has been changed a lot, the old experience did not work, people has their own new design. “Zero discharge mud systems” are urgently required because of the environment protection. Auger box, screw conveyor can be used to collect the drilling cuttings from shale shaker, desander, desilter, mud cleaner, dewatering unit and centrifuge, then transfer them to a catch pit for later processing. In some development company where the government did not have strict regulation on environment protection, they even do not use any mud system, and let the drilling fluids discharged directly. They may face big problem in the future.
Dewatering unit is required to work together with the system, it can make further process of the fluids after processed by centrifuge after the well is finished.
The mud tank is designed similar to 40 feet standard container, it is more convenient to transport in any countries in the world. All the lifting device, dimension, skid is same with container, and we put GN solids control equipments on top of it.
If you required Close Loop mud System for oil & gas drilling, pls contact GN solids control, our service including design, consultant, manufacture and shipment.

GN solids control choose Italy Oli brand vibrating motor for all our shale shakers. Vibration motor is important components for shale shaker, I will introduce briefly about vibrating motor installation & maintenance.
1 How to install vibrating motor ?
 shale shaker vibrator (1). Before installing vibrator, turn off and lock out/tag out all energy sources to mounting structure according to ANSI standards。
(2). If using a cutting torch or welding, test atmosphere for gas level or dust content.
(3). Make sure mounting surface is strong and flat, 0.25 mm acros vibrator feet. (This will minimize internal stress to vibrator casting when tightening mount bolts.
(4) Make sure mounting surface and vibrator are clean and free of debris, paint, and oxidation.
(5) Before installing vibrator onto mount, apply thread sealing compound to all bolts.
(6) After the vibrator has been operated for 10 to 20 minutes, check bolt torque. Tighten if necessary
2 How to maintain vibrating motor?
(1)Clean dust on shell regularly
(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker
(3) Inspect the cable, whether there is wear, hold down, crushing, etc.
(4) the vibration motor should be under good lubrication during operation:
Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃
During running, every 2000 working hours user should makeup LGHP2 lubricate grease once. Every bearing can not be filled over 25.8g.

GNZS703 shale shaker is widely used for oil and gas drilling and directional drilling in the world.
1 shaker deck adjustment
LMSS
A spring-loaded plunger and reversible pawl provide a ratcheting action during movement of the operating handle. A full 180 degrees of movement is possible in both directions. Depending on pawl setting, moving the handle in one direction turns the jack screw to raise or lower the screen frame, while in the other direction the jack screw remains stationary during handle movement. The spring-loaded pawl permits the operator to switch the direction to either raise or lower the screen frame, as required.The angle of the discharge end of the screen frame is infinitely adjustable within the equipment’s available range.
(1)Inspect discharge duct connection on side of hopper for leaks. Tighten connection and/or add silicone sealant to prevent leakage.
(2)Inspect cover on unused hopper discharge connection for leaks. Tighten connection and/or add silicone sealant to prevent leakage.
(3)Using a water hose, wash off accumulated process material from screen frame, interior of hopper and AWD angle adjustment components.
(4)Excess process material in these areas may impede angle adjustment of screen frame and can reduce screen frame vibration if the frame bottoms out on the buildup.
(5)Check for and remove any accumulation of process material or other obstruction in feeder interior. Feeder blockage may cause excessive splashing and uneven distribution of slurry onto the screen bed.

Last month GN shipped 2 sets of 800gpm mud cleaner to a China Government Company for HDD project. They checked our complete mud system taken to CIPPE, and would like to request 2 sets similar one with small changes.
Now we have standard HDD mud system( mud cleaner) with standard equipments and specs for 150gpm, 350gpm, 500gpm, 800gpm, 1000gpm. Clients can make smaller changes according to his separate requirement.
 800gpm mud cleaner for HDD To make some changes, such system can be used for water well drilling, coal bed methane, geothermal well drilling, diamond drilling, core drilling etc projects. So sometimes clients ask us to make a system with 2 functions( can be used for 2 different projects, and can meet the flow rate requirement for each project). So they can save cost for another set mud cleaner.
How to design the mud tank for the mud cleaner?
１ confirm type of the mud tank, trailer mounted, skid mounted or Hydraulic lift type.
2 confirm the dimension of the mud tank
You need to consider 3aspects, 1 required storage capacity 2 transportation limit in Client’s country 3 international shipments limit, by container, by bulk cargo or by flat rack container.
3 confirm the qty of the mud tank(according to required mud storage capacity and equipments required place)
4 how many compartments for each tank( according to equipments and function of each compartment)
5 layout of the equipments on the tank

What is Sand Control?
By Oilfield glossary, sand control is one of the process of well completions. “The installation of equipment or application of techniques to prevent migration of reservoir sand into the wellbore or near-wellbore area. In weak formations, sand control may be necessary to maintain the structure of the reservoir around the wellbore. In other formation types, the migration of sand and fines into the near wellbore area may severely restrict production. Each of these conditions requires different treatments. The principal sand-control techniques include gravel packing and sand consolidation.”
 sand control Sand control focusing on gravel packing, the most popular choice.
Gravel packing involves the complete placement of selected gravel across the production interval to prevent the production of formation fines or sand. Any gap or interruption in the pack coverage will enable undesirable sand or fines to enter the producing system.
It includes the following components:
1 production tubing
2 production casing
3 Gravel-pack packer
4 Gravel placed in casing and perforations
5 Gravel pack screen
6 Sump packer
Sand control has always played an important role in oil production, but solids control plays an important role in oil well drilling. They are utilized in different area.
Solids control is a technique used for well drilling to provide prepared drilling fluids for drilling rigs. Drilling fluid maintenance cost, clean up, and disposal cost as well as the overall cost of boring can be reduced dramatically when proper solids control techniques are utilized.

GN solids control exported several sets of drilling mud system to Amazon region, including Ecuador. We can produce the complete drilling mud separation system, including shale shaker, vacuum degasser, desander, desilter, decanter centrifuge, vertical cutting dryer, mud tank, etc.
Ecuador produces more oil than it needs for domestic consumption and thus it is one of the country’s leading exports. Therefore, any new drilling for oil is not intended to meet local demand but is intended for export overseas, most likely to Japan and the United States.
 drilling mud separation system Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.
Drilling mud separation system
As the drill bit grinds rocks into drill cuttings, these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over shale shakers.
The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.

GN 2-WAY Flow Divider is designed to maximize the solids removal capabilities of shale shaker. It is mainly used for GNZS703 tandem shale shaker, GNZS852 triple shale shaker.
Function of flow divider for LMSS
 flow divider
- Ensures even distribution of liquid and solids to downstream shakers
- Eliminates need for back tanks and shaker bypasses
- Minimizes the effect of pitch and heave
Solids removal efficiencies are dramatically increased by the Flow divider, which distributes fluids/solids equally to multiple downstream shale shakers. Positive sealing weir gates are removable, allowing flow per selected shaker or installed omitting flow. The Flow divider eliminates the need for back tanks and shaker bypasses and minimizes the effect of pitch and heave. The unit is available in four sizes: 2,3, 4, 5, and 6 way.
Mud from the flow line enters the rear of the Flow divider (1) where it contacts a baffle (2) allowing the flow to pass under and sometimes over before it flows over the weirs (3), and divides the liquid and solids equally between the desired number of shaker feed ports (4). Positive-sealing weir gates permit flow to the downstream shakers .
1 Eliminates the need for a back tank and shaker by-pass
2 Minimize the effect of pitch and heave
3 Reduce overall space requirement
4 Fit easily onto most rigs
5 It is applicable for all GN shakers
