Drilling cuttings drying system is the main part of closed-loop system for drilling fluid treatment. It recovers as much drilling fluid as possible by processing drilling cuttings with high humidity. This week, GN Solid Control completed the manufacture of two sets of vertical cuttings drying system. The cuttings drying system will soon be shipped to customers in China domestic market.

Vertical cuttings drying system is mostly used to treat oil base mud and oil base mud drilling cuttings. The whole system is mainly composed of cuttings drying module and fine particle removal module. Each module has a key core separation device to treat the drill cuttings.

1) Vertical Cuttings drying module

Vertical cuttings dryer is the key equipment of cuttings drying module. Usually, drill cuttings are fed into the drill cuttings drying device by vacuum pump or screw conveyer. Under the action of centrifugal force, the oil will be separated from the drilling cuttings, goes through the screen opening of screen basket, and enter the collecting tank. Regarding the opening sizes of the drying screen, GN Solids Control offers 3 sizes for option: 250 microns, 350 misrcons and 500 microns, which can be used to dry cuttings of different sizes. GN Solids Control advanced design vertical cuttings dryer is equipped with a flushing system and an air knife system for cleaning the mud collecting trough and screen to avoid blockage.

2) Fine Particle Removal Module
High speed decanter centrifuge is the key equipment of this module. The liquid effluent discharged by the dryer will be pumped to a high speed decanter centrifuge for further treatment to remove fine particles in drilling fluid. In order to ensure the performance of centrifuge, the high-speed operation, the protection of vulnerable parts and the use of materials are considered in the manufacturing process of crown solid control. Long time operation and less maintenance ensure the efficiency and economic benefits of the equipment.

In the cuttings drying system, mud tanks are used to hold equipment and collect and store drilling fluids. Cuttings discharged from the drying device and centrifuge into the dryer can be conveyed through the screw conveyor device, which is widely used to transport solid materials.

GN Solids Control makes high quality composite material replacement shaker screen for most of the popular shale shaker models.

Many customers do not know the difference of composite material screen, so they do not why the composite screen performance and lifetime is better than the traditional metal frame screens. They are wondering about the manufacturing process of composite screen. They want to understand and know more exactly what’s involved in making the composite screens so they better positioned to make decision about purchasing.

Below is some basic information on what’s involved in the process of composite material shaker screen manufacturing. It is just a high level overview of the operation to help clients understand a little more about composite screens.

What is the A to Z process to make one screen? (i.e. which machine is used first in the process, what does it do, what machine is used next, what does it do……. And so on)?

The main process for making composite material shaker screen include following steps:
Step A: Metal or steel cutting and Metal frame welding by robot and machine.
Step B: Plastic mixing, heating and cuttings ( It’s also done by GN Solids Control) It’s automatic production to produce the required plasitic ball.
Step C: Put the metal frame into the mould and use the plastic injection machine to do the injection to make composite frame.
Step D: Cut the wiremesh into correct size by wiremesh cuttings machine which is original in rolls.
Step E: Heat Press the wiremesh to the composite frame. The key is tension of the wiremsh. GN Solids Control owns patent technology for the pretension treatment of shaker screen making.
Step F: Cutting the edge of the screen to cut off the redundant wiremesh at the edge.
Step G: If the screen is equipped with rubber, GN Solids Control workers will glue the rubber on screen frames.
Step H: Label and Marking
Step I: Packing the screen into carton box.

Cuttings dryer (Vertical cuttings dryer and high G force cuttings dryer) and decanter centrifuge is the major equipment for drilling waste management separation. Cuttings dryer machine is used to remove the big sizes solids from the drill cuttings. Decanter centrifuge is used after cuttings dryer to treat the liquid recovered from cuttings dryer.

Below is the major models cuttings dryer and decanter centrifuge supplied by GN Solids Control for oil and gas drilling field:

1) GN Vertical Cuttings dryer: Model # GNCD930E. It is designed to treat oil based mud and cuttings. In some cases, it can also be used to treat water based mud. While treating oil based mud, it can reduce OOC to ≤5. And per different jobsite reports, less than 5% OOC is achievable.

2) GN high G force cuttings dryer. It is a kind of shale shaker with high G force to treat water based mud and cuttings.

3) GN High Configuration high speed Decanter Centrifuges. Model GNLW363C. GN Solids Control does offer fixed speed control, variable frequency control, and full hydraulic drive for optional for the popular size 14 inch decanter centrifuge.

4) Normal speed big bowl decanter centrifuge, model GNLW452C. It is a economic standard fixed speed centrifuge.

It is a middle speed decanter centrifuge for barite recovery. GN Solids Control also make big bowl high speed decanter centrifuge for waste management fine solids separation.

GN Solids Control is normally recommend client to choose VFD. As the hydraulic system FHD delivery time is much longer. And the hydraulic system is complex for maintenance. While VFD panel are mostly standard components, it is easy for maintenance and the cost is lower.

Besides cuttings dryers and decanter centrifuge, GN Solids Control is also offer other waste management equipment, like screw conveyor, drilling cuttings solidification unit, dewatering unit, cuttings skips, solids vacuum pump, etc…

Recently, a full set of vertical cuttings dryer system is finished and under running testing. After running test in the factory, the system will be packed and shipped to a Chinese domestic market to treat oil base mud and cuttings.

GN Solids Control is specialized in drilling waste management equipment. All GN drilling waste management equipment are specially design with higher material standard for anti-abrasive and reliable servicers. GN cost higher than other solids control companies, so GN equipment price is higher than other Chinese suppliers, who mostly used the same standard solids control equipment for waste management.

The system the client choosing is GN portable1-skid cuttings drying system for oil based mud and cuttings. The system can be used on rig site or off rig site.

GN 1-skid vertical cuttings dryer system includes below processing units:
1) A set of vertical cuttings dryer GNCD930C is used to dry the cuttings. The vertical cuttings dryer is complete with flush screw pump and telescopic skid. After the VG dryer separation, the oil on cuttings can be reduced to 5% less.
2) A set of decanter centrifuge unit. It is complete with screw feeding pump and a small holding tank. The decanter centrifuge can remove ultrafine solids less than 2 ~ 5 microns.

The flow line processing line of the vertical cuttings dryer unit is normally as below:
1) While the cuttings drying system used at rig site, screw conveyors are used under shale shakers and mud cleaner to collect drill cuttings and transfer to vertical cuttings dryer.
2) After separated by the vertical cuttings dryer, the dryer solids discharged fall down to an inclined screw conveyor and transferred out. The recovered drilling fluids is too heavy to be reused for drilling, so decanter centrifuge is used after it to remove the ultrafine solids and reduce the mud weight.

GN Solids Control oil sludge treatment system is mainly used to recover valuable oil in the sludge, and the sludge treatment process can generate greater economic benefits. At the same time, the emission of harmful substances has been greatly reduced. Recently, GN Solid Control completed the manufacture of a full set sludge treatment system. The system is currently undergoing final assembly and factory testing and will be shipped to a waste management customer in Asia.

The working principle of the sludge treatment system is oil, water and solids three-phase separation. Therefore, GN Solids Control sludge treatment system is mainly composed of three parts: coarse particle separation unit, fine particle separation unit and oil-water separation unit.
The coarse shaker screen is used to remove large particulate solids from the sludge. Before feeding the shale shaker, the operator needs to dilute the sludge with solids content less than 20% for pump transfer.

GN Solids Control oily sludge treatment system has a sludge vacuum pump, which is ideal for sludge transport. The shale shaker is located on a canister that collects liquid through the vibrating screen. A mud agitator is installed in the tank to prevent solid precipitation.

A decanter centrifuge is used for fine particle separation. GN Solid Control is capable of providing 9 to 30 inch decanter centrifuges. The feed pump draws sludge from the tank under the shaker screen and feeds it to the centrifuge. During the separation process, the fine solids are removed, and the oil-water mixture is discharged to further separate the three phases.

GN Solid Control uses a disc centrifuge for oil, water and very little solids separation. Disc centrifuges can operate at higher speeds, allowing oil and water to be separated. Depending on the customer’s working conditions and use, a chemical dosing device is required to help remove oil from the solids.
According to different material handling requirements, GN Solid Control has designed three types of sludge treatment systems: GNOST-01A, GNOST-05A and GNOST-15A. For more information on sludge handling systems, please feel free to contact GN Solids Control.
