Drilling waste management is one of the core system GN Solids Control produces, it includes the drilling cuttings separation and also the drilling fluids separation. Dewatering unit, which is also called chemical dosing unit is one of the important components of the drilling fluid treatment systems.

In some countries and regions, it is a must that a drilling rig must be accompanied with a dewatering unit and a dewatering centrifuge, for one thing, more drilling mud could be recycled, which means to reduce the cost and save money. For another thing, it is reducing the harmful components to be discharged to the soil or environment, it helps to protect the surroundings.

GN Solids Control has been providing the dewatering unit for many years, and the dewatering unit now are more and more widely used for different applications, such as:

1. Oil and gas drilling fluids separation. After being used for a certain time, there are more and more extra fine particles in the drilling fluids, even too fine to be separated out by a centrifuge. By adding some chemicals into the fluid, the extra fine particles flocculate into bigger ones to be separated out by centrifuge.

2. In TBM, Piling and other projects, when the slurry is of higher viscosity or need to be added with some chemicals, the dewatering unit is playing an important role, just as shown in the picture, the treatment was successful.

3. In oily sludge separation projects, the added chemicals helps to separate the oil from the cuttings, which greatly increase the efficiency of centrifuge and oil water separator.

GNLW Series decanter centrifuge, especially GNLW363G-VFD, GNLW553-VFD centrifuges are always ideal choice for working together with dewatering unit. Besides those models, GN also has centrifuges with bigger length-diameter ratio for clearer separation.

Recently, GN has produced for 2 different clients who worked for similar projects, with following equipment and solutions:
1. GN big bowl 22 inch diameter decanter centrifuges.
2. GN chemical dosing unit
3. GN standard containers.

GN CONTAINERIZED CENTRIFUGE AND DEWATERING

GN has been providing this design for many years, and the technology is quite mature:
1. GNDU2000 Chemical dosing unit. GN has been providing the chemical dosing unit or so called the dewatering unit for many years, since some of GN clients are using GN centrifuges as dewatering centrifuges and prefer GN to make compact design for them. A chemical dosing unit is used to treat the material by some chemical methods, for example, to add some material to reduce the viscosity of material, or to flocculate the extra fine particles into larger ones, which are suitable for centrifuge use.
2. GNLW553C-VFD decanter centrifuge is a big bowl decanter centrifuge with a treating capacity up t to 90 cbm per hour, and the rotating speed could reach 3000 rpm. It is quite suitable for drilling liquid management, especially being used together with chemical dosing system. Normally, the centrifuge treating capacity for material after flocculation would be greatly reduced, that’s why a big bowl centrifuge with a large treating capacity is always used for this application.
3. 20 ft containers for housing the centrifuge and chemical dosing system, which is quite popular design. For one thing, it is more convenient and easy to transport the system when the main equipment are in standard containers. Secondly, the containers give a shield to the equipment, providing a suitable temperature and clean condition. Thirdly, the 2 sets of 20 ft containers could be put one under another, in this way, less room to be occupied.
In this design, GN engineers designed the round shaped ladders for the upper located container with the big bowl decanter centrifuge, when transporting, the ladder could be put into the container.

Per experiences and calculated data, the drilling liquid occupies in any well drilling is between 4 percentage to 10 percentages, no matter in onshore drillings or offshore drillings. Considering its effects on the drilling operation performance, which occupies nearly 50 percentages, the drilling fluid is quite vital to the drilling.

GN Waste Management Equipment

That’s why, a professional drilling manager has to have a professional team for the drilling mud services, or find a qualified drilling fluid service company. In practice, drilling companies or drilling contractors always focus on drilling work, and employing a subcontractor for the solids control system. Each drilling rig has eight systems connected to each other, among which, the solids control system is comparably independent. An expertized drilling fluid company has the right personnel and suitable equipment, and more important, they know how to treat the fluid well.

A professional oil service companies provide following services:
1. Solids control equipment and services. The solids control systems help to treat the drilling fluid directly from the well mouth. It contains three or four phases for separation, including the shale shaker as the first phase, the desander cones as the second phase, the desilter cones as the third. Some include the decanter centrifuge as the forth one. In most solids control systems, there are mixing unit for adding more chemicals into the fluid when necessary.
2. Drilling cuttings waste management systems, in some countries, this part is also regarded as a part of solids control, because this is also for treating the solids from the drilling fluid. Those systems always contains the vertical cuttings dryer, the high G drying shaker and the decanter centrifuge.
3. Drilling fluid waste management, it is the further treatment for the drilling fluid. As the fluid has been used for a long time, this system uses some chemicals to flocculate the extra fine particles into larger ones before being separated out by a decanter centrifuge.
As one of the leading manufacturers of solids control and waste management, GN Solids Control has been providing lots of oil service companies in the world for all above mentioned systems and equipment. For more information or a formal quotation, welcome to contact GN directly.

Hebei GN Solids Control company was established in Year 2007, ever since it was established, GN has developed rapidly but stably. It soon became one of the most famous brands of solids control industry for oil and gas drilling. During the years of development and also in order to meet the new demands of this industry, GN has expended the product line, now GN core products cover the complete solids control system and the waste management systems.
GN 2nd factory

GN 2nd factory, for decanter centrifuges

Decanter centrifuge is the most important and most widely used equipment in the solids control system and waste management system, it could cover such following roles:
1. middle speed decanter centrifuge for solids control system, for recovering the barite from the drilling mud. Normally, for this application we need a big bowl centrifuge to work at 1800RMP and the ideal length-diameter ratio of the bowl is 2. So GNLW 452 with 18 inch bowl diameter is an ideal choice.
2. high speed decanter centrifuge for the fine particles with diameter ranging from 2 to 5 microns. In most cases GN clients use GNLW363 with 14 inch bowl diameter for this use. For solids control high speed decanter centrifuge, an economic configuration GNLW363 with fixed speed is OK.
3. drilling fluids waste management and drilling cuttings waste management systems, we suggest you to use GNLW363 high configurations for option, it uses the best material and serves as VFD controlled control panels, to achieve different speeds per jobsite condition.
Besides GNLW363 and GNLW452, which are most popular models, GN has different centrifuges with different sizes, like the GNLW223, with 9 inch diameter bowl as baby centrifuge, GNLW453 big bowl centrifuge, with 18 inch bowl diameter as GNLW452 but the length-diameter ratio as 3, and also GNLW553 with 22 inch diameter bowl as super big bowl decanter centrifuge.
Since the previous producing yard is not enough to meet the requests from clients, GN constructed the 2nd factory especially for decanter centrifuges.
