The drilling operator might know that after several times reuse of the drilling mud, there will accumulate more and more ultra fine solids in the mud that cannot be separated out with physical method even by using high speed decanter centrifuge unit.
The accumulated solids will rise up the mud specific gravity that will greatly affect the mud performance. While, in order to keep the normal density of the mud, under this circumstance, the flocculation no doubt is the most popular method to be used.

The flocculation process is produced in a type of machine called polymer mixing unit. This unit is used to mix the polymer that will be fed into the centrifuge to gather the fine solids in the mud. This polymer mixing unit is always connected with the centrifuge unit in the solids control system. After the separation by primary solids control equipment like shale shaker and cyclone unit, most of the solids larger than 5 microns could be removed out. The centrifuge unit plays an important role in this flocculation process. Sometimes, this centrifuge is called dewatering centrifuge.
GN’s polymer mixing unit is designed as 3 compartments mixing tank with automatic dosing conveyor and agitating device. Dry chemicals and water are fed into the first compartment for mixing, and then overflow into the second compartment for maturing process. The third compartment is used to store the solutions waiting for use.

The material of this machine body is PP. At each compartment, there is installed one automatic agitator with stainless steel made agitating shaft and impeller. The chemicals feed hopper is also made of SS304.

In order to realize the continuously mixing, the tank compartments are installed with liquid level control device. The mixing, maturing and storing process continuously transfer with low labor cost. The PLC design makes the operator adjust the solution concentration as per request, high automatic degree, and no need human watch over.
GN could provide the polymer mixing unit with dewatering centrifuge containerized for weather proof. For more information, welcome click to see GN Dewatering System.

Shale shaker is a most popular equipment uses in drilling mud primary solids control system. According to different processing result and mud condition, the operator may choose the shale shakers with different vibration motions. Nowadays, the most often heard of the shale shaker vibration motion are the linear motion and elliptical motion. GN now has a new development shaker could realize the vibration motion changing during running between linear motion and progressive elliptical motion.

Below the Dual Vibration Motion Shale Shaker Parameters:

GN’s dual motion shale shaker has 2 units vibrators, comparing with other brand dual motion shaker with 3 units vibrators, GN’s shaker is more cost competitive. The changing of the vibration is realized by operation on the control panel, no need to adjust the eccentric block of the vibration motors.

GN’s dual motion shale shaker is based on the shaker model GNZS594E with 4-panel screens that the material of which would be both steel frame and composite material available. Under the screen, there are patented design rubber sealing strips are inlayed into the screen frame which could ensure a better sealing performance. With the high G force up to 8, this dual motion shale shaker could also be used as a cuttings dryer shaker by replacing the weir feeder with a hopper feeder so that the auger could deliver the cuttings into the hopper feeder conveniently.

The advantages of GN’s shale shaker are structure simple, easy for operation and maintenance, one shaker for various applications by changing different type’s hopper. The cost is also competitive.

Shale shaker is one of the main equipment in GN’s production line. GN also developed the own latest version decanter centrifuge and cuttings dryer unit. Please feel free to contact with us for more information.

The modular waste cuttings drying units are meaning the separate equipment used for drilling waste cuttings drying processing. Equipment with frame, skid, beneath installed tank, these equipments could be used both independently and worked as an assembled drilling waste cuttings management system.

The reason that GN solids control made this kind of design is to provide more customized solution and save the customers with great funds. According to the feedback from the customers who are always working on the oilfield, GN firstly launched the skid mounted drilling waste cuttings management system with the key equipment vertical cuttings dryer and waste decanter centrifuge mounted on the same skid. This complete skid could be moved by only 1 trailer, which is the customers’ preference. While some other customers came to GN and ask whether they could get single equipment and connecting with their existing waste cuttings drying equipment. Or due to the limited space on site, they cannot put a 40 ft skid on the site, they are seeking some units could be located more freely. The modular waste cuttings units are exactly what they are looking for.
GN’s modular waste cuttings drying unit series includes telescopic skid vertical cuttings dryer and decanter centrifuge, High G force drying shaker with under located catching tank, the intermediary tank specially for effluence storage, waste cuttings transferring unit and the waste collection container unit.
According to the base of the drilling mud, the user could choose to use the cutting dryer or high G drying shaker as the critical equipment to make a complete waste cuttings drying system. Comparing with the 40ft size design, the modular unit has the advantages of freely located onsite and the connecting is more customized. The user also could choose several units of the complete line according to their budget.
GN’s modular waste cuttings drying units have been used onsite and the feedback is returned good. Keeping providing the customer with good solution and bringing benefit for the customer is always GN’s purpose.

As a leading drilling mud recycling equipments manufacturer, GN solids control is keeping design new products that can be applied on the oil field. With more and more new products launched, GN’s products line is getting much wider. Besides the normal solids control equipment and system drilling waste cuttings management system, GN solids control has developed the waste cuttings solidification system for disposal of the waste materials.

The waste cuttings solidification system could also be called as curing system. It always includes 3 parts: waste cuttings collection unit, curing agent storage unit and solidification and mixing unit. GN’s solidification unit is also design like this, the picture shown how does it look like.
The waste cuttings collection part of this unit is a big opening hopper which can collect the waste cuttings conveyed from the primary solids control system. In case the screw conveyor onsite broken down, the operator could use an excavator to put the cuttings into the hopper.
Under the hopper, there is also a screw conveyor could transfer the cutting to the mixing bowl unit.
GN’s solidification system has 2 stainless steel material tanks that used for storing the curing agent. One tank is for cement powder, the other one is for other curing agent. According to different site condition, the operator could add the different curing agent into the mixing bowl. The curing agent is also transferred to the mixing unit by separate screw conveyors.
The waste cuttings solidification and mixing unit is also made from stainless steel with 2 inlet ports controlled by valves. This 2 inlet ports is used to feed the water and other acid or alkali liquid that helpful for curing processing into the mixing bowl. The stainless steel material would have a better anti-corrosive feature for these liquids. The feed rate into the mixing bowl of the waste cuttings and curing agent are all adjustable.
After fully mixed, the hazardous material in the waste cuttings would be closed and will not leak into the nature. The cured material could be buried directly or used for road paving.
GN’s waste cuttings solidification system could be connected with the normal solids control system and drilling waste cuttings management system. After drying firstly by the cuttings drying system, a better solidification effect would be got. According to different site condition, the operators choose to use screw conveyor or cutting pump to transfer the cuttings. And the layout of the equipment will be little different. For more information on GN’s solidification system and waste cuttings drying system, please contact with GN sales team for an elegant brochure.

Still feel difficult to find a good solution to dispose the drilling waste cuttings? GN solids control now has developed the complete treating system for to drying the drilling cuttings and recover the drilling liquid stick on the cuttings maximally.

As per the market feedback and customer’s requirements, GN has independently designed 2 series waste cuttings management system with the Model No. of GNCM-40A and GNCM-40B.

The Configuration of GN Drilling Waste Cuttings Drying System

First Stage separation: GN’s drilling waste cuttings drying system mainly includes 2 modules, in which the first module is the vertical cuttings dryer system. The cuttings dryer model of GNCD930 is designed with fixed speed and variable speed. The cuttings with size larger than 250 microns could be removed by the screen located inside the dryer bowl. By using the material of stainless steel, the screen would have better features of anti-corrosion. With the air knife and flushing system on the cover of the dryer, the dryer could consistently for longer time without blocking on the screen. The super high speed of 1200RPM could produce the G-force of 750. If application for the oil based drilling cuttings, the oil content could be reduced down to 3-5 percent.

Second Stage Separation: The fluid going through the screen opening of the cutting dryer would be fed into the high speed decanter centrifuge series of GNLW363CG with working RPM of 3200. Here, the solids down to 2 microns could be separated out.

In this system, both the cuttings dryer and decanter centrifuge have fixed speed and variable speed models for option which could meet the customer’s request for different drilling mud conditions. GN’s VFD control panel is PLC smart design with visual and touchable screen for easier operation.

For this system, we also provide the feeding pump system. And as per customer’s option, GN could also provide the cuttings delivery system screw conveyor for feeding and discharge.

The customer could choose to locate the decanter centrifuge on the telescopic frame or catching tank. That is also the difference between the model of GNCM40-A and GNCM-40B. The GNCM-40A is to put the centrifuge on the telescopic frame with the height adjustable, the discharged clean liquid would pipeline manifold guiding to other catching tank. While the GNCM-40B is self with the catching tank beneath the decanter centrifuge, the liquid could be stored in the catching tank and wait for pumped to reuse.

GN drilling waste cuttings drying system is an excellent solution to make the cuttings dry so as suitable for transportation. And it maximally recovers the drilling liquid to reduce the drilling cost.
