It is a common knowledge that in the solids control system for a drilling rig, no matter for the land rigs or for the offshores, the shale shaker plays the most important role for separating out the solids waste from the mud recycling unit, and it is also the shale shaker which waste the most of the liquid on the cuttings discharged from the shaker. That’s why, in many countries, there is a must to equip another drilling cuttings treatment system alongside the rig.
A drilling cuttings waste management system is used for further separation of the drilling waste discharged from the shale shaker and mud cleaner, most of which are from the shakers. For one thing, the drilling cuttings waste management system helps to dry the cuttings for later transportation, on the other hand, it increased the drilling liquid amount to be recycled. Both are saving money. In case of OBM mud, the operators always need a vertical cuttings dryer and a high speed decanter centrifuge, while for WBM mud, operators always use a high G drying shaker and a decanter centrifuge.
In some cases, the ViST Shaker screen device could replace the drilling cuttings waste management system, or at least to some degree, reduced the work for the cuttings separation works. Generally speaking, the ViST shaker screen device has following advantages:

ViST shaker device

1. It is suitable for both WBM and OBM mud in a solids control system.
2. It is a compact structure, and only use an air compressor as power source, and one set of ViST could serve up to 3 sets of shale shakers.
3. It is designed to be suitable for different shaker models.
4. In practice, it helps to save the liquid amount by 30% to 50%.
Now for GNZS703 and GNZS594 series shale shakers, there are ViST device for option.

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.

GN Solids Control is one of the leading brands for solids control and waste management system, and second to none ranks among Chinese manufacturers in this industry. A lot of worldwide famous oil companies and oil drilling companies are using GN equipment and comprehensive solutions, including SINOPEC, CNPC and COSL. Recently, GN delivered main equipment for 2 sets of drilling cuttings waste management systems for CNPC.

GN BIG BOWL CENTRIFUGE FOR CNPC

Drilling cuttings are solids discharge from the drilling rig solids controls system, from the shakers, desander and desilters. After the solids control system’s first 3 phases separating, the drilling fluids are returned back to the system without the solids particle. But the separated-out particles are still too wet. For one thing, it is a waste for valuable drilling fluid. Secondly, it could damage to the environment if disposed directly. That’s why it is not only necessary but also mandatory to do some further treatment for the drilling cuttings.
GN Solids Control has zero discharge solutions for both WBM and OBM. And this order, combining the vertical cuttings dryer and decanter centrifuge, is for the oil based mud. A vertical cuttings dryer is specially designed for the oil based mud separation. GNCD930 series vertical cuttings dryers could dry the drilling cuttings to reach OOC value to 5%. The vertical cuttings dryer is running as the drying step of a washing machine. The vertical cuttings dryer is equipped with a screen basket with certain mesh number. Fluids pass the mesh and collected, while cuttings are stopped by mesh and falls down.
GNLW series decanter centrifuges with VFD control panels are used after the vertical cuttings dryer to remove the particles from 2 to 5 microns from the liquid. Most common model is GNLW363CG-VFD, a medium sized centrifuge with a high rotating speed. But for bigger treating capacity, GN has GNLW453C-VFD and GNLW553-VFD available, both of high rotating speed while bowl sizes are respectively 18 inch and 22 inch. In this project, clients chose GNLW453C-VFD.
Pls contact GN for more information.

Does a HDD mud recycling system need a decanter centrifuge? How to use the decanter centrifuge for HDD?

In most cases, there is no need to use a decanter centrifuge in a HDD mud recycling system. One thing is because the drilling mud for HDD project is not as complicated as the mud for the oil and gas solids control, and even in some oil and gas solids control systems, there is no centrifuge. The second is because that the cost for a decanter centrifuge is high, the centrifuge itself is more expensive than other equipment, and the centrifuge need professional staff to operate it and need more careful maintenance.

Centrifuge for HDD

GN Centrifuge used for HDD and CBM

GN Mud Recycling Systems for HDD, CBM and other drillings.

But according to the newly established laws and registrations in a lot of countries, the treating result is of higher standard than before, and now it is quite necessary to employ a decanter centrifuge for HDD mud recycling system. Like in China, the leading HDD contractor CPP added into their new mud recycling system a decanter centrifuge.
GNLW452C is a quite suitable model as a HDD decanter centrifuge, it is used after the desilter cones and the middle speed centrifuge is to separate out the particles from 5 to 7 microns. The big bowl design enables GNLW452 to have a large capacity.

If we have an existing HDD mud recycling system, how can we add a GNLW452 into it?

GN has solutions and the design was well tested at jobsite. The GNLW452 could be mounted on a skid and a screw pump and the control panel ( as a VFD control panel) is mounted on skid, below the centrifuge. The screw pump is used to feed the centrifuge from desilter cone. Solids discharge are collected and liquid flows back to desilter tank. This circle also helps to reduce the mud weight.

For more information, welcome to contact GN.

Since 2007, GN Solids America LLC has been dedicated to research and development of solids control in various drilling industry to provide efficient and cost effective machineries to the industries.  Within everyone in the company’s involvement toward to the same goal, we have been leading exporter in China on solids control machinery manufacture.  As time goes by, we have been export over sixty plus countries around the world and become first machinery provider who got certify by API in China and become standard vendor to both domestic China projects and international projects alike.  Within years of direct feedback from the field of drilling operation, we have expended the product line future on reuse the treated cutting from the oil field to achieve zero-discharge goal. Now we present the GN series solidification Unit.

gn solids china

To achieve zero-discharge goal for treated drill cutting, the GN series solidification unit’s function is to added proper ratio of bounding material to the treated drilling cutting and mixing them together for bounding and hardening.  The finished bounding drilling cutting with other chemical mixing together will avoid soil penetrating that outcome the soil pollution.  The hardening agents should be well mixed with the drilling cuttings for a certain time, than by means of physical and chemical transformation, the harmful and toxic components are transformed, sealed and fixed into safe materials and become some other solids without pollution and to be used as construction materials. GN Solidification Unit is the optional treatment for the drilling cuttings.  Our company’s prospect not only drilling contractors who like to take the zero-discharge task future, but also waste treating company who have waste treating contracted with drilling company.  GN series solidification unit can improve the drilling waste management project capacity and possible increase the revenue by selling treated solids control cutting for materials of civil construction
